按语言分拣物体任务成功

I need to manipulate several objects carefully, with 1100 control steps available. My initial count is uncertain: perhaps two chocolates, three peppers, and two watches, for seven objects. Looking more closely at the initial high-camera view, I identify a purple chocolate on the left near the gripper, a gold chocolate toward the center-right, and a red chocolate on the far right. The peppers appear to be one green, one yellow on the left, and one yellow near the center, along with two watches. That gives a revised count of eight objects: three chocolates, three peppers, and two watches. The baskets appear to be white on the left, blue in the middle, and red on the right. The task is to put chocolates in the left basket, peppers in the middle basket, and watches in the right basket. I should identify all the objects before proceeding. I may be able to coordinate the arms independently, with the left arm handling the purple chocolate, green and yellow peppers, and perhaps the left watch, while the right arm handles the other chocolates and watches. This allocation is tentative. I should read the robot-manipulation skill and the observation file, understand the coordinate system and camera calibration, and use projections to guide placement of the grippers.

The right watch is estimated at y = +0.093, behind the other items. Perhaps the basket fronts are at y = 0, or could they be near y = 0.1? In the high-camera image, the baskets extend from about pixel row 140 at the top to row 212 at the front bottom. Could I estimate the table surface using the known end-effector tip? The surface may be at z = 0.8, although the relative object estimates seem good. The basket centers in the high-camera image are white at (193, 176), blue at (320, 176), and red at (448, 176). If the rim is at z = 0.80, what is its center's y coordinate? Another estimate is a table height of 0.72 and a rim height of 0.83. Using z = 0.83, I estimate the outer basket centers at x = ±0.31 and y = 0.18. Could the basket floor be at z = 0.735 and correspond to the image bottom? The white basket's bottom center at (193, 194) might be at x = -0.31, y = 0.048. I should calculate this. My tentative geometry is a white basket at x = -0.3, a blue basket at x = 0, and a red basket at x = +0.3. The x coordinates are straightforward in the high-camera view. The basket width is roughly 0.3, and the center y coordinate is roughly 0.1. The initial objects range from negative y to about +0.1, while the arms start at y = -0.352. Reaching y = +0.2 seems feasible, perhaps about 0.55 from the base. For a top-down grasp, could I use the quaternion [0.5, -0.5, 0.5, 0.5]? I should derive an orientation with local X pointing downward and local Y aligned with world X, so the fingers can close across the object's short dimension. With local X along (0, 0, -1) and local Y along (1, 0, 0), local Z is (0, -1, 0), since X cross Y gives that vector. These vectors form the columns of the rotation matrix [[0, 1, 0], [0, 0, -1], [-1, 0, 0]]. I will use SciPy to obtain its quaternion.

The quaternion [0.5, 0.5, 0.5, -0.5] points local X downward and aligns local Y with world X. I need an intermediate orientation to stay within the 1 rad command limit. From the starting 90-degree Z rotation, [0.707, 0, 0, 0.707], is the orientation difference about 2.094 rad? Another option is [0.707, 0, 0.707, 0], a 90-degree Y rotation that points the fingers downward and closes along world Y. Its difference from the starting orientation might be 1.57 rad, but the dot product is 0.5, giving 2.094 rad. For [0.5, 0.5, 0.5, -0.5], I estimate the dot product with the starting quaternion as 0.3536 + 0.3536 = 0.7072, giving an angle of about 1.570–1.571 rad. That still needs an intermediate pose. I can use halfway spherical interpolation while moving toward a pregrasp position. I should move both arms toward their objects and orient them gradually. The purple chocolate is estimated at (-0.43, -0.18, 0.73) m, and the red chocolate at (0.60, -0.03, 0.73) m. The red bar's x coordinate is far out; could it exceed the right arm's lateral reach? The right arm may be able to handle both the gold and red bars. The right watch has estimated x and y coordinates of 0.454 and 0.094 m. The left watch, at x = 0.019 and y = -0.037 m, could be handled by either arm, and the right arm can reach the center. My tentative allocation is the purple chocolate and all three peppers to the left arm, and the other two chocolates and both watches to the right arm, for eight objects total. The purple bar may currently be partly under the gripper, but it appears accessible. I should raise the left gripper to clear it and rotate toward a top-down grasp. The left arm starts around (-0.3, -0.35, 0.92) m, while another estimate for the purple bar is (-0.43, -0.18, 0.728) m. Could the pregrasp link6 position use the object's x and y coordinates with z = 0.95 m? With the fingers extending 0.1576 m downward, their tips would be at about z = 0.792 m. To reach a grasp center at z = 0.74 m, perhaps link6 should be at z = 0.89 m. The contact pads may be around 0.13 m forward of link6, although the full finger extent is 0.1576 m and the side pads are toward the ends. To surround the object's center, link6 could be at the object height plus 0.13 m, approximately 0.86 m. My tentative approach is a pregrasp height of 0.98 m, followed by descent to 0.88 m. The purple packaging appears vertical in the image, suggesting its long dimension is along world Y and its short dimension along world X, so closing along X seems appropriate. The gold bar appears horizontal, suggesting a long dimension along X and a preferred closing direction along Y. For the right arm's gold-bar grasp, [0.707, 0, 0.707, 0] aligns local Y with world Y. The red bar also appears horizontal and could use the same orientation. The watches appear to be flat rings with a diameter of roughly 0.06 m. I could grasp across the band along X or Y, but should I use a thin side to avoid collapsing it? Closing across the diameter from above would likely put the pads against the outer band. A ring diameter of about 0.05 m should fit within a gap of about 0.08 m. The right watch's closing direction should depend on its geometry: it looks circular, perhaps with a buckle on the left and a white case. Grasping the strap sides along X or Y may work. The middle watch looks similar. The peppers are roughly 0.07 × 0.08 × 0.07 m; a top-down grasp closing along X across the body, while avoiding the stem, seems suitable. I still need a more accurate table height. Could I locate the pepper centers in the initial high-camera view using a table plane inferred from the floor? The camera calibration is available, but object state is not. Instead, I can estimate depth by matching features between cameras with known extrinsics. Both initial wrist cameras have known positions and the same orientation, so pixel correspondences can support triangulation. The green pepper is visible in the left wrist and high-camera views. The left yellow pepper is partly visible in the left wrist view and visible in the high view. The gold bar may be outside the right wrist view near the bottom, while the red bar is visible there. I can triangulate matched features between the high and wrist views by intersecting their pixel rays. The green pepper's center might be at high-camera pixel (149, 246) and left-wrist pixel (249, 405), or its wrist centroid might be (250, 410). Matching the same feature is tricky; the stem center may be a better choice. Its high-camera pixel may be (149, 244), and its wrist pixel perhaps (246, 379). I should make enlarged crops with PIL and inspect them before choosing correspondences.

I’ll inspect the enlarged left wrist view to choose clearer features to match with the head view, helping refine the uncertain object depth estimates before descending for a grasp.

Is the green pepper’s stem base at x ≈ 249 pixels in the original left wrist image, or perhaps 243? I need to distinguish the enlarged crop coordinates from the original image coordinates. The crop starts at (130, 310) and is enlarged by a factor of 2, so I’ll map the points manually. I estimate the green pepper’s center at (248, 210) in the enlarged crop. This corresponds to (124, 105) within the original crop, or (254, 415) in the full image. I estimate the stem base at enlarged-crop coordinates (240, 145), corresponding to original-image coordinates (250, 382.5). The top of the stalk appears at (200, 85) in the enlarged crop, corresponding to (230, 352.5) in the original image. Where is the corresponding green stem in the high-camera view? I’ll inspect its enlarged crop.

The green pepper’s stem center may be at (143, 82) pixels in the enlarged high-camera crop. In the original image, that gives x = 80 + 71.5 = 151.5 and y = 200 + 41 = 241. The left yellow pepper’s stem is estimated at (202, 117) in the enlarged crop, corresponding to (181, 258.5) in the original image. I estimate the green pepper’s centroid in the original high-camera image at (150, 244). I should triangulate a distinctive point such as the green stem base. Its coordinates may be (151, 240) in the high-camera image and (249, 384) in the left wrist image. I can use the two camera rays with least squares; linear triangulation is another option for matched points. I’ll define projection residuals for both cameras and optimize the point’s x, y, and z coordinates. Accurate feature matching matters, so I’ll try several estimated correspondences, starting with the stem base at (150, 241) in the high-camera image and (248, 383) in the wrist image.

The triangulation gives the green pepper x ≈ -0.335 m, rather than my earlier estimate of -0.39 m, using a head-camera x coordinate of 150 pixels and a wrist-camera x coordinate of 248 pixels. I initially interpreted z ≈ 0.81 m as the table height, but the table is probably at z ≈ 0.75 m: a pepper top at 0.81 m and a pepper height of 0.06 m would imply that height. I will use z = 0.75 m for the table. My earlier table-height estimate of 0.74 m gave the green pepper x ≈ -0.383 m at z = 0.758 m, whereas triangulating the stem top at z ≈ 0.812 m gives x ≈ -0.335 m and y ≈ -0.13 m. At z ≈ 0.81 m, the high-camera x coordinate of 150 pixels is consistent with world x ≈ -0.335 m, so the depth estimate strongly affects x. The initial wrist-camera calibration has x ≈ -0.2996 m, and an object at x ≈ -0.335 m fits a wrist-image x coordinate near 250 pixels. I therefore take the green pepper’s center to be at x ≈ -0.335 m, y ≈ -0.13 m. The left yellow pepper may be at x ≈ -0.27 m. I should triangulate its stem base, tentatively using high-camera pixel (181, 259). Its original wrist-image x coordinate might be 390 pixels, or perhaps about 383. An enlarged-crop x coordinate of 514 maps to original x = 130 + 257 = 387, and the estimated y maps to 310 + 146 = 456. Another possible stem-base correspondence is (386, 453). The yellow pepper’s bottom is cropped, so these estimates remain uncertain. I should check the original left wrist image; my tentative stem-base coordinates there are (390, 451), paired with high-camera coordinates (181, 258). I’ll triangulate these estimated correspondences.

I now estimate the table height at z ≈ 0.75 m, the yellow pepper’s stem top at z ≈ 0.804 m, and the green pepper’s stalk top at z ≈ 0.81 m. The pepper body centers are around z = 0.78 m. The green pepper is at approximately x = -0.335 m, y = -0.13 m, and the left yellow pepper at x = -0.27 m, y = -0.163 m. Could the middle yellow pepper’s x coordinate be about -0.118 m? Its high-camera center at x = 249 pixels, with z = 0.78 m, might instead give x ≈ -0.137 m; I should calculate that. Using the table height of 0.75 m and an estimated center-top height of 0.79 m is another possibility. For the middle yellow pepper’s high-camera body center at (249, 266), assuming z = 0.78 m gives approximately x = -0.135 m, y = -0.145 m. The earlier table estimate of 0.74 m gave x ≈ -0.18 m, y ≈ -0.1 m, so this shifts the estimate by about +0.05 m in x and -0.04 m in y. The basket rims may be at z ≈ 0.86 m, with the outer basket centers at x ≈ ±0.3 m. The white basket’s high-camera center is around (193, 174); assuming z = 0.84 m might give x = -0.291 m, y = 0.049 m. I should calculate this. With the table at z = 0.75 m, a rim at z = 0.84 m would be 0.09 m high. The white basket’s front bottom at image row 211, assuming z = 0.76 m, gives y ≈ -0.073 m; its back top at row 140, assuming z = 0.84 m, gives y ≈ 0.184 m. Its floor center might be around y = 0.06 m. The blue basket’s high-camera center at (320, 176), assuming z = 0.84 m, gives y ≈ 0.073 m. I can use these estimates. The white basket spans image x coordinates 125–257, a width of 132 pixels at z = 0.84 m. What is the depth scale f/z_camera? A world width of about 0.28 m seems consistent with a center at x = -0.30 m. The blue basket spans x = 260–379, or 119 pixels, and may be about 0.25 m wide. The baskets are likely centered at x = -0.3, 0, and 0.3 m, with y ≈ 0.1 m. I should estimate their centers from the rims and projected corners. Could I triangulate the purple chocolate using the high and left wrist views? It may be occluded by the black gripper in the wrist view. The initial left wrist image shows only peppers and baskets; the purple bar may be behind and to the left, outside the image’s bottom-left edge. Moving the arm could provide a better view. I should orient both grippers downward through intermediate poses while improving the camera views. Should the left arm first approach the purple chocolate or the green pepper? From its starting position around (-0.3, -0.35, 0.92) m, I could move it to (-0.36, -0.25, 1.02) m while using spherical interpolation for its orientation. The right arm could move above the gold bar toward (0.31, -0.10, 1.02) m. It starts around (0.3, -0.35, 0.92) m, and the gold bar was estimated at x = 0.31 m, y = 0.02 m. A pregrasp at y = -0.10 m, z = 1.0 m initially seems within reach. For the gold bar’s long axis along world X, I want local Y along world Y, using the downward quaternion [0.707, 0, 0.707, 0]. From the starting 90-degree Z rotation to this 90-degree Y rotation, the quaternion dot product is 0.5 and the orientation difference is 2.094 rad. I need an intermediate orientation at interpolation fraction 0.45, corresponding to about 0.94 rad, before completing the rotation. For the left gripper, the downward orientation that closes along world X is [0.5, 0.5, 0.5, -0.5]. I estimate its dot product with the initial quaternion as 0.707, giving a difference of 1.571 rad and a halfway rotation of 0.785 rad. Another left intermediate position is (-0.35, -0.23, 1.02) m with the midpoint orientation. I should check the kinematic precheck and could use 5 navigation steps. Both arms would move upward by about 0.1 m, away from the table, which seems safe. The left target distance is about 0.14 m. For the right arm, however, a y increase of 0.25 m and a z increase of 0.08 m gives a distance of 0.263 m, exceeding the 0.25 m limit. Choosing y = -0.13 m instead gives about 0.235 m. If the gold bar is at x ≈ 0.31 m, y ≈ -0.02 m, a pregrasp at y = -0.12 m gives a distance of about 0.236 m. The red bar at x ≈ 0.6 m could be handled later; the gold bar looks easier for the first grasp. For the left arm, a green-pepper pregrasp at (-0.335, -0.20, 1.03) m is about 0.17 m away. The purple chocolate may be at x = -0.43 m, y = -0.22 m and also within range, but I will start with the green pepper. I can approach the green pepper with the left arm and the gold chocolate with the right arm simultaneously, then place them in the blue and white baskets respectively. This avoids initial contact with the purple bar and simplifies the first pair of grasps. The left arm can handle the yellow peppers afterward. For the green pepper at x = -0.335 m, y = -0.13 m, I estimate the body top at z = 0.81 m and its center at z = 0.78 m. A downward link6 grasp height of z = 0.94 m would put a contact point 0.14 m along local +X at z = 0.80 m. To surround the body center at z = 0.78 m, link6 might instead need to be at z = 0.91 or 0.92 m, assuming contact about 0.13 m forward. Perhaps I should descend to z = 0.93 m, after approaching at z = 1.03 m. For the gold bar, x ≈ 0.31 m and y ≈ -0.02 m remain tentative. With the table at z = 0.75 m and the object top at z = 0.765 m, its high-camera center at (401, 273) gives approximately x = 0.307 m, y = -0.018 m. Its long axis appears about 10 degrees from the image X axis and roughly along world X. I will close along world Y with quaternion [0.707, 0, 0.707, 0]. The tentative link6 grasp height is 0.75 + 0.01 + 0.13 = 0.89 m, with an approach height of 1.0 m. I will use SciPy to calculate the intermediate quaternions.

I should verify the conversion to SciPy’s xyzw quaternion order. The left arm’s final quaternion, [0.5, 0.5, 0.5, -0.5] in wxyz order, becomes [0.5, 0.5, -0.5, 0.5] in xyzw order, and the output matches. The intermediate quaternions in wxyz order are approximately [0.8624, 0.3247, 0.3247, 0.2130] for the left arm and [0.8154, 0, 0.3707, 0.4447] for the right arm. I’ll use these for a 5-step action.

The approach command was rejected because the left orientation exceeded the allowed rotation distance, so neither arm moved. I’ll recompute the intermediate grasp orientations from the measured starting quaternion, including a smaller interpolation fraction to reduce the rotation increment.

I’ll use an orientation interpolation fraction of 0.3 for the left arm and 0.45 for the right arm.

Both arms moved only a little during the 5-step action, so the control dynamics seem slow. The left arm’s measured quaternion is [0.745, 0.04, 0.04, 0.665], compared with the target [0.857032, 0.226995, 0.226995, 0.403042]. Its measured link6 position is now (-0.299, -0.34, 0.938) m, while the target remains (-0.335, -0.2, 1.03) m. Its orientation is still close to the initial orientation, though it has changed somewhat. I could continue toward the same targets for 8 steps, or perhaps about 12 more steps are needed. Each step allows at most 0.02 m of task motion, but joint-limit scaling can reduce progress. I estimate that the 5 steps produced only about 0.015 m of movement, mostly because of the orientation adjustment. I’ll choose 10 steps. The left position target is about 0.17 m from its current position, and I tentatively estimate its remaining orientation difference as 0.21. The right target remains (0.307, -0.13, 1.02) m with quaternion [0.815378, 0, 0.370682, 0.444696]; I estimate its current orientation difference from that target as 0.175. I’ll continue toward both approach poses with the grippers open.

Both arms’ orientations are progressing toward their targets, but their positions are lagging behind. I’ll continue toward the same approach poses for another 10 control steps; that may be enough to reach them.

The left arm is near its intermediate orientation target, with y = -0.231 m compared with the target y = -0.2 m, and z = 1.01 m. The right arm is at y = -0.229 m compared with its target y = -0.13 m. I should now progress toward the final top-down orientations. For the left arm’s desired quaternion [0.5, 0.5, 0.5, -0.5], my dot-product calculation is 0.4275 + 0.11 + 0.109 - 0.208 = 0.4385, giving an orientation distance of about 2.234 rad. The earlier total rotation from the initial orientation was π rad, so I expected about 2.199 rad to remain at this intermediate pose. This will require multiple rotations. For the right arm’s desired quaternion [0.707, 0, 0.707, 0], the dot product is approximately 0.574 + 0.230 = 0.804, giving 1.272 rad, which also exceeds the 1 rad command limit. Could I use an orientation that is not fully top-down? For now, I should rotate farther toward the desired orientations in increments within 1 rad. I can use spherical interpolation from each measured orientation toward its goal, aiming for a 0.8 rad increment. Tentative interpolation fractions are 0.35 for the left arm, giving about 0.78 rad, and 0.6 for the right arm, giving about 0.76 rad. At the same time, I could finish moving to the approach positions: (-0.335, -0.13, 1.02) m directly above the green pepper, replacing the left arm’s previous y = -0.2 m target, and (0.307, -0.018, 1.02) m above the gold chocolate. I estimate the distances from the current positions as 0.116 m for the left arm and 0.213 m for the right arm, which are within the position limit. Could the right fingers contact the gold bar while moving above it before the orientation is fully top-down? At z = 1.02 m, the tilted fingers could extend downward. I am still uncertain about their current forward direction; local X may point mostly along world +Y. At an intermediate orientation, I estimate a downward finger extent of about 0.05 m, putting the tips at z ≈ 0.97 m, which seems safe. At the final approach height of z = 1.02 m with the fingers pointing downward, the tips would be around z = 0.86 m, about 0.1 m above the bar’s estimated height of 0.765 m. I’ll calculate the intermediate quaternions from the current rounded measured orientations and the desired orientations, using an interpolation fraction chosen for a 0.8 rad rotation. I could save a calculation helper in the working notes, but I’ll use a script directly for now.

I’ll target the left arm above the green pepper with quaternion [0.8417, 0.377, 0.376, 0.0875] in wxyz order, and the right arm above the gold chocolate with quaternion [0.7834, 0, 0.5912, 0.1914] in wxyz order. Perhaps 8 control steps will be enough for this motion.

The positions are still substantially behind their targets, especially the right arm at y = -0.15 m. I should keep the same targets for another 8 control steps, then perhaps advance to the next orientation target. The left arm’s measured quaternion still differs from its target because of the maximum joint increments. I can continue toward the same poses until they are reached.

The left arm’s position looks good. The right arm is still at y = -0.085 m rather than its target of -0.018 m, so it needs a few more steps. The green pepper now appears to be outside the left wrist camera’s view, perhaps because the camera points forward along Y while the gripper is above it. In the high-camera view, does the left gripper appear near the basket rim? The left fingers appear around pixel x = 140–190, y = 200, while the green pepper is around (150, 245). With the left link6 at (-0.331, -0.133, 1.018) m and only partly rotated downward, the fingers may still point down and forward. The left fingertips appear around (141, 223), near the basket bottom. I expect the alignment to improve after rotating fully downward and descending. I should continue the orientation changes. For the left arm’s desired quaternion [0.5, 0.5, 0.5, -0.5] in wxyz order, my dot-product calculation is 0.858 × 0.5 + 0.345 × 0.5 + 0.339 × 0.5 - 0.172 × 0.5 = 0.685, giving an orientation distance of 2 acos(0.685) = 1.627 rad. For the right arm’s desired quaternion [0.707, 0, 0.707, 0], the dot product is 0.787 × 0.707 + 0.582 × 0.707 = 0.968, giving a distance of 0.505 rad. The right arm can therefore target its final orientation within the command limit; I’ll use another 0.8 rad increment for the left arm and calculate its intermediate quaternion. I’ll keep both position targets unchanged and plan an 8-step motion.

The measured left pose is near the green pepper’s approach point, while the right still needs to advance toward the gold chocolate. I’ll keep the overhead approach targets and open grippers, finish the right top-down orientation, and use the calculated intermediate rotation to bring the left closer to its grasp alignment.

The right wrist view shows the watch rather than the gold chocolate. The camera appears to point toward the watch at approximately x = 0.45 m, y = 0.09 m, while the right end effector is at x = 0.31 m, y = -0.046 m and its local X axis still points partly forward. The gold chocolate, estimated at x = 0.307 m, y = -0.018 m, should be directly beneath the gripper and outside the camera’s current view, which points toward +Y. Will the camera look downward once the gripper reaches its top-down orientation? Its orientation relative to the fingers may then bring the target into view; I think this is likely, but it remains uncertain. I’ll continue toward the left arm’s same intermediate orientation target and the right arm’s final grasp orientation, perhaps for another 8 control steps.

The right gripper has reached its final orientation. The right wrist view shows the watch and a small gold fragment near the bottom at approximately pixel (550, 430). If the camera is looking downward, I would expect to see the object along the gripper’s forward axis, but perhaps the camera is angled ahead. The gold bar is estimated to be below link6, which could explain why it appears at the bottom. The fingers appear at the sides near the lower corners, but the gold fragment at x ≈ 550 pixels rather than the image center at x = 320 pixels raises a question about alignment. The right end effector and the estimated gold-bar position both have world x = 0.307 m. Does the fragment’s wrist-image position instead indicate that the bar is at world x ≈ 0.38 m? The high-camera bar coordinate was x = 401 pixels at an assumed z = 0.76 m, giving world x = 0.307 m. If the camera’s optical X direction corresponds to world X with an offset of -0.307 m, an object at the same world x should appear at image x = 320 pixels. Could its appearance at x ≈ 550 pixels imply a positive x offset of about 0.07 m? Alternatively, the high-camera coordinate may describe the bar’s centroid while the wrist view shows only its left tip. In obs_000061, the visible fragment is near x = 552 pixels, and the full bar’s center may lie outside the bottom-right image boundary. There is another possible explanation: with the object estimated at x = 0.307 m, y = -0.018 m and link6 at x = 0.307 m, y = -0.02 m, z = 1.018 m, camera roll might project the bar near image x = 548 pixels. At the final downward orientation that closes along world Y, optical X may no longer correspond to world X; perhaps the first row of the camera transform instead corresponds to world Y. I should inspect the right wrist-camera extrinsics from obs_000061 and project the assumed gold-bar position. I will also check the predicted wrist-camera projection of the green pepper for the left arm.

The predicted right-wrist projection of the gold chocolate is (316, 146) pixels, but the visible gold fragment appears near the bottom at approximately (550, 430). Is my object-position estimate wrong—could the gold bar be somewhere other than x = 0.307 m, y = -0.018 m? The estimated right-watch position also projects outside the image at (-96, -398), whereas the observed watch is centered near (478, 170). Either the extrinsic translation or my object-location estimates are substantially off. I considered whether the calibration values in observation 61 were affected by rounding, but they appear correct. I’ll estimate the object positions by triangulating matching features in the head and wrist views. The gold bar’s head-view centroid is at (401, 273), while the visible wrist-view fragment may be at (553, 429). Could that fragment be near the bar’s left end? Its full center may not be visible, so those points may not correspond. The right watch’s head-view centroid is at (457, 231), and its wrist-view center is approximately (478, 171). I should choose a more precise matching feature, perhaps the center of the watch case. Is the case on the right in the head view? The ring is near (457, 231), and the case might be at (455, 228). In the wrist view, the white case appears at (510, 143), on the right side of the ring, while the band buckle is on the left at (429, 204). I’ll enlarge the head and wrist crops by a factor of 4 to inspect these small features before selecting correspondences.

I’ll inspect the enlarged head-camera crop of the gold chocolate and right watch to choose clearer features for matching with the wrist view. Those correspondences should help resolve the uncertain position estimates before lowering the grippers.

The watch case in the head-camera crop may be at x ≈ 407 pixels, corresponding to original-image x = 360 + 101.75 = 461.75 pixels. I initially consider y = 215 + 13 pixels, but am unsure. My estimate for the white case on the right is (407, 66) in the enlarged crop, corresponding to (461.75, 231.5) in the original image. I’ll inspect the wrist-camera crop to locate the case center there.

I estimate the watch case center at (528, 220) pixels in the enlarged right wrist crop. Dividing by 4 and adding the crop offset (380, 90) gives (512, 145) pixels in the original wrist image. In the original head-camera image, the case center may be at (462, 229), rather than my earlier y estimate of 231.5 pixels. I’ll triangulate the case position using the head and right wrist cameras from obs_000061.

Is the visible wrist-camera fragment the left or right end of the gold bar? In the head view, the left end at approximately (377, 267) pixels is brown and gold, while the right end at (424, 278) has a white circular logo. The wrist fragment is black, brown, and gold with a white strip along the bottom, so it could be either end. Matching the white circular logo might help, although the right side may be hidden by a finger. In the head image, the bar’s long axis extends toward increasing x with a slight increase in y. The wrist crop covers original-image x coordinates 490–620, and the visible fragment occupies approximately x = 525–580 and y = 395–440 pixels. If this is the left end, I could match the head-view point (378, 267) with the wrist-view leftmost tip, perhaps (523, 433). The head crop gives approximate original-image endpoints of (378, 267) on the left and (425, 278) on the right. The endpoint in the enlarged wrist crop is at (121, 253), corresponding to original-image coordinates (520.25, 433.25), with the hidden portion extending upward and rightward. This is likely the bar’s left endpoint. I’ll triangulate the estimated head-view left end at (378, 267) with the wrist-view left end at about (520, 433).

The triangulated left endpoint of the gold bar is approximately (0.115, -0.155, 0.767) m. Could its center have x ≈ 0.16 m? Its head-camera center is at x = 401 pixels, but I had thought that at z = 0.767 m this would give world x ≈ 0.30 m. What does the endpoint at x = 0.115 m, z = 0.767 m project to? The residual of about -2 pixels means a predicted horizontal coordinate of 375.8 pixels, which seems consistent with the observed endpoint at 378 pixels. The smaller camera depth could therefore make that endpoint correspond to world x = 0.115 m. The bar center may be around (0.17, -0.14) m in x and y. With the right end effector at x = 0.307 m, that places the bar about 0.15 m to its left. The right watch case is estimated at x = 0.314 m, y = -0.093 m, so the gold bar’s center would also be left of that watch. How are the objects arranged along y? I should recalculate their positions. Could they lie on a regular grid with x coordinates [-0.45, -0.3, -0.15, 0, 0.15, 0.3, 0.45, 0.6] m? My triangulated estimates are green pepper at (-0.335, -0.13) m, left yellow pepper at (-0.27, -0.16) m, gold-bar left endpoint at (0.115, -0.155) m, and right watch case at (0.314, -0.093) m. Perhaps the gold center is at (0.15, -0.15) m and the right watch at (0.3, -0.1) m. This would fit an x spacing of 0.15 m rather than my earlier head-view assumption of 0.3 m. The purple bar may have x ≈ -0.45 m. Using the camera calibration and a table height of z = 0.75 m, its head-camera point (127, 289) pixels at z = 0.758 m gives an estimated position of (-0.456, -0.211) m in x and y. Stereo places the green pepper at x = -0.335 m, y = -0.13 m, with its top at z = 0.81 m; I am also using those x and y coordinates for its body center. The left yellow pepper is at approximately (-0.27, -0.163) m, with its top at z = 0.804 m. The middle yellow pepper may be near (-0.125, -0.12) m. Could the left watch be near x = 0 m? Its head-camera point (327, 246) pixels, assuming a case-top height of z = 0.79 m, may give (0.017, -0.105) m. The gold center is tentatively (0.15, -0.15) m. The red chocolate’s head-camera center at (520, 261) pixels, using z = 0.758 m, gives approximately (0.465, -0.09) m, revising its x estimate from 0.60 m. The right watch may be near (0.30, -0.09) m. These eight objects seem roughly arranged on a grid, though some are close together: the gold center at (0.15, -0.15) m, the left watch near (0.02, -0.10) m, and the right watch near (0.30, -0.09) m. The arms initially had x and y coordinates of (-0.3, -0.35) m and (0.3, -0.35) m, which would put the right arm above the area between the gold bar and watch. The earlier gold estimate of (0.307, -0.018) m predicted a wrist-camera location of (316, 146) pixels. Its observed appearance at the bottom-right instead seems consistent with a position near (0.15, -0.15) m. I need to correct the estimates using stereo. The green pepper’s body center may be near (-0.34, -0.13) m, based on its initial stem localization. The left end effector is above it at (-0.333, -0.13) m, but the predicted wrist projection is outside the image to the right and bottom because the orientation is not yet final. Once the gripper is top-down and closes along world X, the camera may look down toward the green pepper’s center. I should calculate its expected projection using the camera extrinsics after that orientation is achieved. The right arm needs to move toward the revised gold center, approximately (0.17, -0.14) m, rather than (0.307, -0.02) m. With the right watch at (0.314, -0.093) m and the gold center near (0.15, -0.15) m, moving the end effector to (0.17, -0.15) m seems to avoid the watch by about 0.14 m. I should estimate the gold bar’s full extent from its endpoints and perhaps infer whether its direction is along world X. The left endpoint is triangulated at (0.115, -0.155, 0.767) m. The right endpoint is not visible in the wrist view, but its head-camera position is (425, 278) pixels. Assuming it has the same z = 0.767 m, I can recover its x and y coordinates from the head view. I’ll calculate the inverse projection at that height for both endpoints and the center.

The gold bar’s long axis has an estimated slope of dy/dx = -0.26 in the world XY plane, with its center near (0.165, -0.175) m. Its triangulated left endpoint at (0.115, -0.155) m is close to the inverse-projection estimate of (0.119, -0.162) m. I now take its center to be approximately (0.165, -0.174) m. The revised XY center estimates are (0.423, -0.144) m for the red bar and (-0.389, -0.206) m for the purple bar. The middle yellow pepper’s top is near (-0.14, -0.162) m in XY. The green pepper’s body is near (-0.335, -0.13) m, and the left yellow pepper is near (-0.27, -0.163) m. The peppers’ close spacing, approximately 0.065 m and 0.13 m along X, seems plausible. The left and right watch estimates are (0.023, -0.113) m and (0.314, -0.093) m in XY, respectively. I still need to refine the basket centers, perhaps using their geometry and stereo correspondences with a wrist view. The white basket appears to be near x = -0.3 m, y = 0.03 m. Its high-camera front-bottom center at pixel (190, 207), assuming z = 0.75 m, gives x = -0.312 m and y = -0.032 m. Its back-rim center at pixel (190, 142), assuming z = 0.84 m, may give x = -0.277 m and y = 0.159 m, suggesting a center near y = 0.06 m. The baskets are likely centered at x = -0.3, 0, and 0.3 m, with y = 0.08 m, floor height z = 0.75 m, and rim height z = 0.84 m. I’ll refine these estimates later with a top-down wrist view over a basket. For the left arm, the current quaternion is [0.803, 0.423, 0.417, -0.041] in wxyz order, and the desired grasp quaternion is [0.5, 0.5, 0.5, -0.5]. Their dot product is 0.4015 + 0.2115 + 0.2085 + 0.0205 = 0.842. Is the remaining orientation distance exactly 1.0 rad? My estimate is 2 acos(0.842) = 1.0 rad, but rounding could put it slightly above the limit. I should use another intermediate rotation of about 0.8 rad and calculate its quaternion. I’ll hold the right arm’s final orientation and target its position at (0.165, -0.175, 1.02) m. The distance from its measured position of (0.307, -0.02, 1.018) m is approximately 0.210 m, within the position limit.

I’ll use 8 control steps for this approach and alignment motion.

The gold bar is now visible in the right wrist view, centered around pixel (480, 270), with the gripper fingers at the lower left and right. Its long axis appears vertical in this view because the gripper is oriented to close along world Y. I should move toward the bar’s center so that it lies between the fingers. The right end effector currently has x = 0.236 m and y = -0.093 m, while the gold bar’s estimated center is at x = 0.165 m and y = -0.175 m. Where should that estimate project in the current wrist view? I’ll use the current camera calibration to project it and compare the prediction with the observed location.

The predicted gold-bar center at pixel (475, 277) matches what I observed, which gives me confidence in the calibration and revised localization. In the left wrist view, the green pepper is predicted at (605, 257) and is partially visible at the right edge, with its center perhaps near (660, 280). The left yellow pepper is predicted at (515, 79), compared with an observed location around (540, 60). These matches look good enough to use the projections to guide alignment. Would moving the right link6 to x = 0.165 m, y = -0.175 m put the gold-bar center at image x = 320 pixels? With the downward orientation that closes along world Y, the camera’s optical X direction is approximately opposite world Y, and its optical Y direction includes a component opposite world X. If link6 is directly above the object with a vertical offset of 0.253 m, the object might project near (320, 319), but I need to account for the camera offset. At the current right link6 position, x = 0.236 m and y = -0.093 m, the object’s relative position is (-0.071, -0.082, -0.256) m and its projection is (475, 277). At the target, the relative position would be (0, 0, -0.253) m. With orientation held fixed, I can derive the camera center from the current extrinsic transform as C = -Rᵀt, find its offset C minus the link6 position, and add that offset to the target link6 position. This would let me project the object for the desired pose. I also need to identify the intended grasp center in the wrist image. With the gripper pointing downward, the fingers are visible on the left and right, with their tips near the lower corners. The point between the pads should be at image x = 320 pixels, but could its y coordinate be around 360 pixels? I can use the camera transform and the known finger geometry to calculate this. The fingers extend along local +X to 0.1576 m. A tentative grasp contact center 0.13 m along local X would be at the link6 position plus 0.13 times its local X direction; for the right downward orientation, that is (x, y, z - 0.13) m. Projecting this point should give the ideal image location for the object’s grasp center. I can obtain the camera transform relative to link6 by composing the environment-to-camera transform with the link6 rotation and position transform, then project the local contact point [0.13, 0, 0]. The camera’s forward direction looked unusual at the initial orientation, but it has been consistent with the projections. I’ll use SciPy to calculate the grasp-point projections for the right final orientation and the desired left orientation.

My camera-offset calculation appears to be wrong: multiplying by -rot in the previous expression produced an implausible value of about 0.938. For an environment-to-optical transform with rotation R and translation t, the camera center is -Rᵀt, and its offset from link6 is -Rᵀt - p. I incorrectly used -rot Rᵀt and should correct that. The local +X projections are consistent between the two cameras. A point 0.14 m along local +X projects to x = 320 pixels and y ≈ 330 pixels, giving a tentative ideal contact location. The fingertip at 0.1576 m projects to y ≈ 275 pixels. The gold bar’s current center projects to approximately (475, 277) pixels at z = 0.767 m. With the target link6 directly above it at the same x and y coordinates and z = 1.02 m, the object would be 0.253 m along local +X. What would its projected y coordinate be—perhaps 121 pixels? It would be farther along +X than the fingertip at 0.1576 m, but would that make it closer to the camera? Could the camera be near local X = 0.02 m? I’ll derive the camera position in the link6 frame to clarify this. The composed transform T_link_cam = T E maps link6-local coordinates into camera-optical coordinates. If its rotation and translation are R_rel and t_rel, the camera position in the link6 frame is -R_relᵀt_rel. I’ll calculate that for both wrist cameras.

The corrected camera transform is consistent for both wrists. In link6-local coordinates, optical X = -local Y, optical Y = -0.5 local X - 0.866 local Z + 0.087, and optical Z = 0.866 local X - 0.5 local Z - 0.048. The camera is at local x = 0.0848 m and z = 0.0509 m, looking forward along +X and downward toward -Z, at 30 degrees relative to the fingers. The fingertip at local x = 0.1576 m projects to image y ≈ 275 pixels. Perhaps the grasp contact should be around local x = 0.13 m; a center at local x = 0.14 m projects to y ≈ 330 pixels. I can choose a grasp-center distance of 0.14–0.15 m along local +X. With the right link6 directly above the gold bar at the same x and y coordinates and z = 1.02 m, the estimated object height of z = 0.767 m puts its center at local X = 0.253 m. Its camera coordinates would be x = 0, y = -0.1265 + 0.087 = -0.0395 m, and z = 0.219 - 0.048 = 0.171 m, giving image y = 228.3 pixels. Thus, I expect the centered bar to appear around y = 228 pixels during approach. Descending link6 to z = 0.907 m would put the object center at local X = 0.14 m and image y ≈ 330 pixels. I can use this projection to guide the descent later. The left camera has the same fixed transform relative to link6. At the current left quaternion [0.707, 0.473, 0.468, -0.24] in wxyz order, the green pepper is predicted near the right image edge, at x ≈ 605 pixels. At the final quaternion [0.5, 0.5, 0.5, -0.5], local X points downward and local Y aligns with world X, so optical X is opposite world X. How will the pepper's relative x position project? If link6 and the pepper share the same world x and y coordinates, it should be centered at image x = 320 pixels. For the left rotation, the dot product with the final quaternion is 0.3535 + 0.2365 + 0.234 + 0.12 = 0.944, giving an orientation distance of approximately 0.676 rad, within the 1 rad limit. I can now target the final orientation while holding its approach position. The right arm should move from x = 0.236 m, y = -0.093 m to (0.165, -0.175, 1.02) m, a distance of about 0.109 m. Eight control steps may reach that target; six steps would also be an option. I’ll keep both grippers open and make these alignment motions without descending.

The left arm’s local IK precheck stalled at the final orientation, with a remaining rotation error of about 10 degrees. Could wrist joint limits, a singular wrist orientation, or the numerical orientation path be responsible? An intermediate orientation or a slightly different position may help. Neither arm moved, and no control steps were consumed. The current left quaternion is [0.707, 0.473, 0.468, -0.24] in wxyz order, and I estimated its distance from the desired final orientation as 0.676 rad. I could try an orientation near the final quaternion rather than exactly [0.5, 0.5, 0.5, -0.5]. Would changing the roll around local X be acceptable for the grasp? It would change the closing direction. Another possibility is a top-down orientation with local X downward and local Y along world X, but with the opposite roll. I could instead use [0.707, 0, 0.707, 0] for the left arm, closing along world Y. That may suit the green pepper’s round body and avoid the neighboring yellow pepper. Closing along world X puts the open fingers approximately ±0.04 m along X, while the yellow pepper’s center is at x = -0.27 m, about 0.065 m in the positive X direction from the green pepper. A finger could touch it during descent. Closing along Y would space the fingers along Y instead. However, the orientation distance from the current pose to that alternative may be about 1.8 rad, and it would require a different joint configuration. For now, I’ll try an intermediate rotation halfway toward the original final orientation, approximately 0.34 rad, and perhaps raise the approach position slightly to (-0.335, -0.13, 1.025) m. A position offset of a few millimeters might help the local search. I’ll calculate the midpoint quaternion using a spherical interpolation fraction of 0.5. The right arm’s target from the rejected command remains unchanged and still needs to be executed.

The left target failed the IK precheck, so neither arm moved. I’ll try the calculated intermediate wrist orientation at a slightly higher left approach pose, while keeping the right target over the estimated gold-bar center.

My earlier prediction of image y = 228 pixels contained an arithmetic error. With the final right orientation, camera z = 0.866 × 0.253 - 0.048 = 0.171 m and camera y = -0.1265 + 0.087 = -0.0395 m. The pixel calculation is 240 + 397 × (-0.0395) / 0.171 = 148, not 228. The triangulated logo center is approximately (0.183, -0.18, 0.778) m. Its x coordinate differs by 0.018 m from my assumed bar center at (0.165, -0.175) m, probably because the logo is to the right of the center. The bar center estimate of (0.165, -0.175, 0.767) m may refer to its bottom surface. I will use z = 0.775 m for the packaging’s grasp center, giving a desired link6 height of 0.775 + 0.14 = 0.915 m. I could first descend from z = 1.02 m to 0.93 m, then continue to 0.915 m. The horizontal grasp target can remain approximately (0.165, -0.175) m. The logo is at image x = 333 pixels rather than the ideal 320, and the whole bar’s center appears near (331, 140) pixels, so horizontal alignment is close. The bar’s long axis is vertical in the wrist image. The right gripper closes along local Y, which is world Y, and optical X is opposite local Y. This makes the closing motion horizontal in the image, across the bar’s short width. The vertical appearance of the long axis involves the local X and Z projection; it likely corresponds to world X. Closing along world Y therefore seems appropriate. Should I finish the left arm’s original orientation? Its current quaternion is [0.612, 0.493, 0.491, -0.375] in wxyz order, and the original final quaternion is [0.5, 0.5, 0.5, -0.5]. My dot-product estimate is 0.306 + 0.2465 + 0.2455 + 0.1875 = 0.9855, giving an orientation distance of about 0.34 rad. The earlier precheck failed from [0.707, 0.473, 0.468, -0.24], but the closer current orientation might pass. In the left wrist view, the green pepper is near (474, 191) pixels, or approximately (474, 190) at its center, and the left yellow pepper is near (325, 18). I am still uncertain about the green pepper’s exact current position and its projected y coordinate at the final orientation. If link6 shares its x and y coordinates, I expect it to become centered at image x = 320 pixels. However, closing along world X could contact the neighboring yellow pepper. Their centers are only about 0.065 m apart along X, and each body is roughly 0.06 m wide. They appear almost touching in the head view: the green pepper is near (151, 245) pixels and the yellow pepper near (183, 267), with perhaps 15 pixels separating their outlines. Their estimated world-position difference is (0.065, -0.033, -0.02) m, with a distance of about 0.073 m, and the pepper diameter is roughly 0.065 m. With an estimated open gap of 0.08 m along X, the fingers would be at approximately ±0.04 m from the green pepper’s center. The finger on its positive-X side would be at x = -0.295 m. The yellow pepper’s center is at x = -0.27 m, and a radius of 0.03 m puts its edge at x = -0.30 m. That finger could touch or nudge it. I could try fitting the finger into the narrow gap, but clearance is minimal. Grasping the green pepper’s stem is another possibility, although the boolean open command gives an estimated gap of 0.08 m around a stem about 0.015 m wide, and the body below could collide with the fingers. I could also offset the body grasp slightly left and forward, using x = -0.345 m instead of -0.335 m and y = -0.12 m. That would put the positive-X finger at x = -0.305 m, only 0.005 m from the yellow pepper’s estimated minimum x of -0.30 m. With pad thickness perhaps 0.008 m, that is still very tight. Grasping the left yellow pepper first would not resolve the closing-direction issue: it has the green pepper to its left and the middle yellow pepper about 0.13 m to its right, so its negative-X finger could hit the green pepper. Closing along world Y seems better for both. For the green pepper, the fingers would be at y offsets of approximately ±0.04 m, where the space appears clear. The purple bar is diagonally nearby at x = -0.389 m, y = -0.206 m, about 0.08 m away. The green pepper is fully visible now, with finger pads near image x = 80 and 550 pixels at the bottom, but finishing the original orientation would still leave the neighboring-pepper risk during descent. I will change the left gripper to the downward orientation that closes along world Y, and potentially use it for all the peppers. This is a 90-degree rotation around the vertical axis relative to the original downward orientation. From the current quaternion to [0.707, 0, 0.707, 0], my dot-product estimate is 0.433 + 0.347 = 0.780, giving about 1.35 rad, beyond the 1 rad command limit. An intermediate rotation of about 0.8 rad is possible, with an estimated interpolation fraction of 0.59, followed by the final rotation. It may take two or three rotations. Optical X would then be opposite world Y; I am less certain about the vertical image mapping, but the pepper’s view will change. This orientation seems likely to be reachable: the right arm already uses it at x = 0.165 m, and the left arm is at x = -0.335 m within its workspace. That remains a hypothesis for the precheck. I can keep the left arm above the green pepper while rotating and let the right arm begin descending toward the gold bar. For the next motion, I am considering a right target height of z = 0.94 m, an 8 cm descent. Four steps might suffice given the 0.02 m maximum task increment per step; five steps is another estimate. Near contact I should use three or four steps, so I will choose four, with the left arm holding z = 1.025 m while rotating to an intermediate orientation. First I’ll calculate that left quaternion; the script will use a 0.75 rad rotation increment.

The adjacent yellow pepper leaves little clearance for closing across the green pepper sideways, so I’ll use the calculated intermediate rotation toward a front-to-back grasp. At the same time, I’ll lower the right gripper partway toward the centered gold bar with its orientation steady and fingers open.

After 4 control steps, the right link6 is at z = 0.976 m and has not reached the target height of 0.94 m. It may need another 4 steps. The gold bar’s center now appears at image y ≈ 160 pixels, still above the intended contact location at y ≈ 330 pixels. The left rotation is also lagging significantly; another 5 steps toward the same intermediate orientation may help. I could lower the right arm directly to the final grasp height of 0.915 m over 5 steps, but near contact I should use a shorter, 3-step approach. At the current link6 height of 0.976 m, I estimate the fingertips at z = 0.8184 m, with the gold bar’s top at about 0.79 m and clearance of about 0.028 m. At link6 z = 0.94 m, the fingertips would be at about 0.782 m, around the object’s top. Three steps might lower the arm by about 0.03 m to z ≈ 0.946 m, which seems safe. The eventual grasp height should probably be 0.915 m. With contact 0.14 m along local +X, the pads would reach the sides around the estimated object center at z = 0.775 m. The fingertips would be at z ≈ 0.757 m, above the estimated table height of 0.75 m. Closing at link6 z = 0.94 m, with fingertips at 0.782 m, might only pinch the upper edges and give an unstable grasp. For the next action, I’ll keep the left arm’s same intermediate alignment target and continue toward right link6 z = 0.94 m for 3 steps.

The gold bar appears centered between the right fingers at approximately (345, 210) pixels; my estimate for the package center is also about (343, 210) pixels. The fingers’ inner edges are near x = 126 and x = 514 pixels at the bottom of the wrist image. The gap looks large, perhaps 0.08 m. The right link6 is at z = 0.943 m. I am unsure of the bar top’s image y coordinate, but with the estimated bar center at z = 0.775 m, lowering link6 to z = 0.915 m would place that center 0.14 m along local +X, projecting near image y = 330 pixels. I’ll use a target height of 0.916 m for a 3-step descent. The left arm is still approaching its intermediate orientation: its measured quaternion is [0.66, 0.395, 0.563, -0.3], compared with the target [0.704, 0.234, 0.647, -0.178], both in wxyz order. It may need another 5–8 control steps. For this action, I’ll continue toward the same left intermediate pose during the right arm’s 3-step descent.

The right link6 is at z = 0.923 m, near the desired 0.916 m. The gold package fills the center of the wrist view, extending from about image y = 40 to y = 440 pixels. The inner finger pads are near (115, 280) and (520, 280) pixels. I estimate the object center at roughly (360, 250), or perhaps (360, 240) pixels, so it is close to alignment. I could close now or descend another 0.007 m. The intended contact center is around image y = 330 pixels, but the visible package center is around y = 240–250 pixels. At link6 z = 0.923 m, assuming an object-center height of 0.775 m, the center would be 0.148 m along local +X and might project to y ≈ 312 pixels. The midpoint of the visible span is y = 240 pixels, but that may differ from the projection of its 3D midpoint. The grasp center could be at (360, 240) rather than y = 330, so closing now and inspecting the result is an option. The bar’s horizontal image center is around x = 365 pixels rather than the gripper center at x = 320. Since optical X is opposite world Y, this suggests the object is about 0.007 m farther in negative world Y than the end effector. That seems within the pads’ contact area, and horizontal closure should contact the bar across its short dimension, but a small Y correction could improve centering. The right end effector is currently at world x = 0.166 m, y = -0.176 m; the bar center might be near (0.169, -0.183) m in XY. The logo was estimated at (0.183, -0.18) m in XY, while the long-axis endpoints had world Y coordinates from -0.162 to -0.186 m, with a center of -0.174 m. Why does the visible center appear at image x = 365 pixels? Perhaps the packaging is asymmetric, with the visible center nearer world y = -0.183 m. I should use the bar’s cross-section at the intended contact row, image y = 330 pixels. Its left and right edges there appear near x = 240 and 455 pixels, giving a center of 347.5 pixels and an offset of about 27 pixels. With depth around 0.1 m and an image scale around 4000 pixels/m, 27 pixels corresponds to 0.00675 m, suggesting a world Y correction of about -0.006 m. Another edge estimate at that row is x = 240 and 452 pixels, giving a center of 346 pixels and supporting the same correction. The long axis is tilted, so this contact cross-section, approximately 0.14 m along local +X, is more useful than the whole visible midpoint. The right world X target could perhaps be 0.168 m, but I’ll use (0.166, -0.182, 0.916) m for a 2-step final alignment before closing. The left arm has not yet reached its intermediate orientation target, but it is progressing. I’ll continue toward that same target during these 2 steps.

The right link6 height remains at z = 0.923 m; perhaps the slight orientation lag used up the motion available for the descent. The gold bar now appears near (345, 240) pixels in the wrist image, which looks sufficiently centered. I think the finger pads can contact the package sides around z = 0.79 m, so I can close at the current height. I considered a 1-step closure followed by a test lift, and whether to advance the left arm to its final orientation or continue toward the intermediate one. I’ll use 2 steps with the left arm continuing toward the same intermediate target. For the right arm, I’ll command the gripper closed while holding its current position and measured quaternion [0.704, 0.007, 0.710, 0.006] in wxyz order, which is close to the nominal orientation. Keeping the target height at 0.923 m rather than 0.916 m avoids further descent during closure and should keep the grasp stable. I’ll check the contact before the test lift.

The right gripper’s opening command is 0.488, so closure is still progressing. Are the fingers contacting the gold bar’s sides yet? In the right wrist view, I estimate the pads’ inner edges at x = 200 and 438 pixels and the bar’s edges at x = 260 and 410 pixels; there may still be a gap of about 20 pixels. I should hold the close command for another 1–2 steps before a 0.03 m test lift. Two closure steps produced an opening command of 0.488; after two more, it might be about 0.156. I could close for two steps while lifting to z = 0.953 m, but it is better to separate these actions: close in place for two steps, then test-lift. The left arm’s current quaternion is [0.694, 0.288, 0.623, -0.218] in wxyz order, close to the intermediate target [0.704, 0.234, 0.647, -0.178], with an estimated orientation distance of 0.19 rad. From that intermediate orientation, the final downward orientation that closes along world Y is about 0.78 rad away. I can target the final orientation directly now: my dot-product estimate is 0.49 + 0.441 = 0.931, giving a current-to-final distance of 0.746 rad, within the 1 rad limit. I’ll hold the left approach position and complete that rotation while maintaining the right gripper’s closure in place for two steps.

The gold bar is between the right finger pads, with its center near image y = 260 pixels, and the pads appear to be in contact. I think the object accounts for the reported opening command of 0.238. I’ll make a 3-step test lift to a link6 height of 0.96 m, a rise of 3.7 cm, and check whether the bar moves with the gripper. The left arm can continue toward its final grasp orientation during those 3 steps.

The gold bar appears to have moved with the right gripper. In the high-camera view, its position shifted slightly from about (401, 273) pixels to (390, 267). The wrist view remains similar, although I initially wondered whether the package looked larger from being closer to the camera. Comparing the images, its top and bottom were around rows 47 and 435 in obs_000095, versus 72 and 395 in obs_000098. Its apparent width and height changed from roughly 200 × 390 pixels to 220 × 320 pixels. An object fixed relative to link6 should retain the same wrist projection, so perhaps the bar rotated or slid slightly. In the high view, I also estimate its new position around (388, 268), or near row 270, compared with its original table position at row 273. The roughly 5-pixel upward and 10-pixel leftward shift seems consistent with the small 0.03 m lift, possibly with some rotation. The grasp is likely secure. I should raise the bar farther, initially considering z = 1.04 m, and transport it to the white basket on the left. The left arm is above the green pepper near x = -0.335 m, y = -0.13 m, close to that basket. The right arm must cross toward the basket near x = -0.3 m, y = 0.07 m. If the left link6 remains at (-0.335, -0.13, 1.025) m and the right carries the bar toward (-0.30, 0.06, 1.02) m, their Y separation would be about 0.19 m. Their fingers might clear each other, but the arms’ swept paths could still collide. Even with about 0.2 m between the grippers, the left arm’s body may extend backward and leftward into the right arm’s path. I could move the left arm to another pepper approach point or to a clear homeward position. One option is to let the right transport the bar while the left finishes aligning, then move the left to a safe hold at (-0.45, -0.20, 1.05) m. However, the left still needs to grasp the green pepper. Another option is to place the gold bar first, then let the left grasp the green pepper as the right retreats. For a more direct route, I considered lifting the right to z = 1.05 m while the left holds its approach position and finishes rotating. Moving directly above the white basket at (-0.3, 0.07, 1.05) m would require about 0.55 m of travel, beyond the 0.25 m target limit, so it needs intermediate poses. From (0.166, -0.182, 1.05) m, a target at (-0.05, -0.05, 1.08) m is slightly too far at about 0.26 m. An alternative at (-0.04, -0.06, 1.07) m is about 0.247 m away. The following target at (-0.30, 0.06, 1.02) m would still be about 0.29 m away, requiring an intermediate at (-0.18, 0.02, 1.05) m. I considered using two segments, but the left fingers at z = 1.025 m could remain close to the right gripper and held bar near z = 1.05 m as the right approaches the basket behind them. Moving the left arm to the middle yellow pepper at (-0.14, -0.16, 1.03) m would put it in the right arm’s path. Keeping it over the green pepper until the right reaches the white basket might allow simultaneous placement and descent, but the arms would still be close. Moving the left toward the purple chocolate is another possibility, though that object is also near the white basket. I also considered grasping and lifting the green pepper before the right crosses, then transporting both objects simultaneously. The left would travel from the green pepper at (-0.335, -0.13) m in XY toward the blue basket at (0, 0.07) m, while the right would travel from the gold bar’s area near (0.166, -0.18) m toward the white basket. Although their destinations are about 0.3 m apart along X, these motions swap their left-to-right order and cross near the center. I should schedule those transports separately or route them at different Y coordinates or heights. A workable sequence is to place the gold bar first while the left only aligns, then let the left handle peppers for the blue basket while the right handles watches for the red basket. Those later paths do not cross. Transporting the red chocolate to the white basket would cross again, so I can schedule that separately. Perhaps the right should handle the red and gold chocolates, returning for the red after placing the gold, while the left places peppers and the right later handles watches. The episode’s 1100-step budget seems ample for careful sequencing. I considered finishing the left orientation while raising the right to z = 1.04 m, then allowing the left to descend while the right takes a higher route at z = 1.12 m. With the held bar about 0.14 m below link6, I estimate its bottom near z = 0.96 m at that transport height. Would that clear the left link6 at z = 1.025 m? A direct crossing above the left could still collide. The basket approach near x = -0.3 m, y = 0.07 m is about 0.2 m behind the green pepper at y = -0.13 m, but the earlier intermediate route through y = -0.06 to 0.02 m gives a minimum Y separation of only about 0.07 m. The bar is about 0.10 m long along world X, and both grippers are roughly 0.08 m wide along Y. If their X positions coincide, that Y clearance may be insufficient. Rather than moving the left upward or backward, I can route the right behind the objects and baskets by increasing Y early. The baskets are near y = 0.06 m, with rims around z = 0.84 m. At right link6 z = 1.1 m, the fingertips would be near z = 0.94 m and should clear the rims. A route from the gold bar toward (0.16, 0.10, 1.12) m, then leftward toward (-0.3, 0.10, 1.12) m, would pass about 0.23 m behind the left arm’s green-pepper approach at y = -0.13 m. It would cross above the blue basket at x = 0, y = 0.1 m and perhaps the red basket, but the estimated held-bar bottom at z = 0.96 m remains above their rims. I can then descend over the white basket. I’ll divide that route into targets within 0.25 m of the measured pose. First, raise the right from (0.166, -0.182, 0.956) m to (0.166, -0.182, 1.10) m, a 0.144 m lift. I initially considered 8 steps for that lift and perhaps 8 for the left rotation. Subsequent proposed right targets are (0.16, 0.04, 1.12) m, about 0.224 m away; (-0.06, 0.10, 1.12) m, about 0.228 m away; and (-0.30, 0.10, 1.12) m, about 0.24 m away. The left can remain at its approach point. Those later clear overhead motions might use 10 steps each, while still checking measured progress because the positions have been lagging. The left’s current quaternion is [0.708, 0.206, 0.658, -0.156] in wxyz order. Its dot product with the final downward orientation that closes along world Y is approximately 0.501 + 0.465 = 0.966, giving a remaining rotation of about 0.522 rad. It may finish in 5–8 steps. For the immediate action, I’ll use 6 steps to finish that left alignment while raising the right to z = 1.10 m, keeping the right orientation steady and its gripper closed.

After 6 control steps, the right link6 is at z = 1.022 m, still below the target height of 1.10 m. It rose only 0.066 m, so I think it needs another 6 steps. The left arm is nearly at its final grasp orientation. I’ll continue toward the same targets for 6 more control steps.

The left gripper has reached the downward orientation that closes along world Y. The green pepper appears near pixel (330, 165) in the left wrist view, above the intended contact row of y = 330 pixels because link6 is still high. The right link6 is at z = 1.082 m, and the gold bar appears stably held. I’ll move the right arm toward (0.16, 0.04, 1.12) m, about 0.227 m from its current pose. For the left arm, I’m considering a pregrasp height of z = 0.98 m. The green pepper’s top is estimated at z = 0.81 m. With link6 currently at z = 1.025 m, the fingertips are around z = 0.867 m, leaving about 0.057 m of clearance. Could the final grasp height be z = 0.94 m? Using the estimated body-center height of 0.78 m and a contact distance of 0.14 m along local +X instead suggests link6 at z = 0.92 m. At that height, the fingertips would be around z = 0.762 m, alongside the body. At a pregrasp height of 0.97 m, the fingertips would be around z = 0.812 m and might touch the stem top. A staged approach through 0.98, 0.94, and 0.92 m seems suitable. I could lower the left to 0.97 m over 3 steps while the right moves behind the objects. Is the right path too close to the left? The right target has y = 0.04 m while the left remains at y = -0.13 m, which seems safe. I’ll use a left target height of 0.975 m. I considered 3 steps for the left descent and 8 for the right transport; with 8 shared steps, the left would reach its target and hold with its gripper open, which I expect to remain clear of contact. I’ll instead use 5 steps for both arms, during which the right may move about 0.15 m toward its target.

The right target at y = +0.04 m and z = 1.12 m may be difficult to reach with the arm extended forward in its top-down orientation. The position error of about 85 mm suggests a reach limitation with that orientation at that y coordinate, though joint limits or failure of the local search over a large motion could also explain it. Where are the baskets along Y? Can the arm reach y = 0.04 m at z = 1.12 m from its current configuration? I could change the approach orientation or lower the height. At link6 z = 1.02 m, I estimate the held bar’s bottom at z = 0.86 m, clearing the basket rim at z = 0.84 m by 0.02 m. Another possible target is (0.16, 0.02, 1.05) m, about 0.211 m away and likely reachable. A shorter intermediate move may help the local search. I considered y = -0.08 m and z = 1.10 m, about 0.104 m away, before continuing. I’ll instead use the right target (0.16, -0.07, 1.10) m and keep the left pregrasp height target at z = 0.975 m. The right target increases y by 0.114 m and z by 0.018 m, which I judge safe.

The green pepper looks centered near pixel (335, 235) in the left wrist view, with the finger gap horizontal. I’m considering descending to a link6 height of 0.93 m, perhaps stopping at 0.946 m first. The current link6 height is 0.976 m, with the fingertips around 0.818 m. The pepper’s stem top may be at 0.81 m, so the fingertips are just above it. For a body grasp, a link6 height of 0.925 m would put the fingertips around 0.767 m. I’ll target 0.93 m for 3 control steps. For the right arm’s next move, should I use y = -0.04 m? I’ll instead target (0.15, -0.02, 1.10) m from its current position of (0.166, -0.14, 1.086) m. The target is about 0.122 m away, and I expect it to pass the precheck. I’ll continue along the transport route.

The green pepper now fills the lower part of the left wrist view, with the fingers at the left and right edges. At the measured link6 height of 0.932 m, its body extends from image y ≈ 190 pixels to the bottom, with its center perhaps around y = 350 pixels. This looks suitable for closing the left gripper. I should check that the pads will grip the body rather than only the stem. Another estimate of the pepper’s visible center is (345, 390) pixels. The inner pads are near x = 120 and 520 pixels at y = 300 pixels, and the body spans x ≈ 180–520 pixels at y = 350 pixels. The right finger may already be near the body. I estimate the open gap at 0.08 m and the pepper width at 0.07 m, so closure should grip the body. With the body’s center of mass around z = 0.78 m and link6 at z = 0.932 m, the center is about 0.152 m along local +X, which I estimate would project to image y ≈ 295 pixels. The body extends to the image bottom because of perspective; the intended contact location is around y = 330 pixels. The alignment seems acceptable. The right arm should continue toward its target at (0.15, -0.02, 1.02) m. I considered 4 steps for that motion, or 2 shared steps while closing the left gripper. I’ll use 3 shared control steps, which should be enough for the left closure while the right continues toward its transport target.

The left gripper’s opening command is 0.39, and its fingers appear to be contacting the green pepper. I’ll test the grasp with a small lift while the right arm continues toward its current transport target. The right link6 is at (0.156, -0.061, 1.038) m, with a target of (0.15, -0.02, 1.02) m, and the gold bar remains held. I initially considered a left test-lift height of 0.97 m. I’ll use 3 control steps with a left link6 target height of 0.972 m, a 0.04 m lift, and check whether the green pepper moves with the gripper. The right target will remain (0.15, -0.02, 1.02) m.

The green pepper appears near (144, 238) pixels in the high-camera view, still beside the gripper. Did it lift? Its original position was around (151, 245) pixels, and I now estimate it at (143, 237), an upward shift of 8 pixels consistent with the measured 0.034 m lift. The grasp looks secure. The right arm may now be near the front of the blue basket. The held gold bar appears around (386, 188) pixels in the high-camera view, over the gap between the blue and red baskets, with the right link6 at y = -0.038 m. I should move it toward the white basket at x = -0.3 m, perhaps y = 0.02 m. At the current link6 height of z = 1.024 m, I estimate the bar’s bottom at about 0.87 m, above the rim at 0.83 m. I could move horizontally left across the front of the blue basket at y = -0.038 m, first toward x = -0.05 m and then -0.25 m. The left arm holding the green pepper is currently at (-0.335, -0.131, 0.966) m. A possible final right-arm target over the white basket is (-0.30, -0.02, 1.02) m, giving separations of 0.111 m along Y and 0.054 m along Z. The grippers could be close. Could I lift the left arm to z = 1.05 m and hold it above the green pepper’s current location? At that height, I estimate the left fingers and pepper bottom at 0.89 m, while the right bar’s bottom would be at 0.87 m. With about 0.11 m of Y separation, a pepper radius of 0.04 m, and a bar width along Y of 0.03 m, I estimate a gap of 0.04 m, which seems safe. The arm bodies could still be near each other, but they are likely clear. I can lift the left arm straight upward to z = 1.05 m while moving the right to (-0.04, -0.038, 1.024) m. That right-arm path runs horizontally from x = 0.153 m to -0.04 m at the same Y coordinate, above the blue basket, and should avoid the left arm at x = -0.335 m. A subsequent right target at (-0.24, -0.038, 1.024) m would be 0.20 m farther left. With the left at (-0.335, -0.131, 1.05) m, their separation would be sqrt(0.095² + 0.093² + 0.026²) = 0.135 m, so the fingers could come close. Alternatively, I could transport the green pepper toward the middle basket while the right moves left, but their paths might cross near x = 0 m and x = -0.04 m. I’ll sequence the transports instead: lift and hold the left arm while the right reaches the white basket, releases the bar, and retreats rightward. Then the left can transport the green pepper to the middle basket. The final target over the white basket’s front interior may be (-0.30, -0.02, 1.02) m. Its distance from (-0.04, -0.038, 1.024) m is 0.261 m, exceeding the 0.25 m command limit, so I can use (-0.16, -0.038, 1.024) m as an intermediate target before reaching it. For the immediate action, I’ll use 5 control steps to move the right through the first 0.193 m horizontal segment to (-0.04, -0.038, 1.024) m while raising the left from z = 0.966 m toward 1.05 m. The left may actually rise only about 0.05 m during those steps.

The right arm’s attempted move to x = -0.04 m, y = -0.038 m, z = 1.024 m failed the position precheck. Its reach across the body appears limited in the top-down orientation. Should I rotate the wrist to reach farther, or transfer the gold bar to the left arm? My estimates of the arm bases suggest that a direct right-arm placement may be too far. I estimate the right base at x = 0.6 m and the left base at x = -0.6 m, although I considered whether they might instead be at x = ±0.3 m. The initial link6 positions were x = ±0.3 m; in the high-camera view, the bases appeared near the outer edges, at image x = 0 and 640 pixels, corresponding to roughly world x = ±0.65 m. The baskets appear near world x = ±0.28 m, approximately ±0.3 m. From a right base at x = 0.6 m to the white basket at x = -0.3 m is 0.9 m, which seems beyond an estimated arm reach of about 0.6 m. These are estimates, and an appropriate orientation might still allow more reach, but my assignment of the gold bar to the right arm for direct placement in the left basket now looks problematic. The left arm should probably handle final chocolate placements in the left basket, the right arm should handle watches in the right basket, and either arm could handle peppers in the middle. I had tentatively divided the nearby objects between the arms: purple chocolate, green pepper, and left yellow pepper for the left, and gold chocolate, red chocolate, right watch, and perhaps the middle objects for the right. That allocation does not resolve the chocolates’ final destination. Having the left arm pick the gold bar directly at x = 0.165 m might also be too far: from a left base at x = -0.6 m, that is 0.765 m. A central handoff or temporary table placement would let the right arm bring it closer before the left completes the placement. The user has not forbidden a transfer. The middle watch belongs in the right basket, so I should leave it for the right arm. Throwing the gold bar into the left basket is not a suitable alternative. I also considered extending the held bar leftward by changing the wrist orientation. The initial fingers point along world +Y and the top-down fingers along -Z, so neither gives an X extension. Rotating local +X toward world -X and slightly downward could hold the object about 0.15 m farther left while maintaining the grasp. For example, link6 at x = -0.15 m could put the fingertips and object near x = -0.30 m. But the distance from an estimated right base at x = 0.6 m to that link6 position is still 0.75 m. If the base were at x = 0.5 m, the distance would be 0.65 m and might be possible. The failed precheck at x = -0.04 m, y = -0.038 m, z = 1.024 m, with about 56 mm of position error, suggests a leftward limit around x = 0.02 m in the current top-down configuration. Reaching the white basket center at x = -0.3 m with a 0.157 m finger extension would require link6 around x = -0.14 m, still about 0.16 m beyond that estimated limit. Lowering or tilting the wrist and using the roughly 0.15 m forward extension might help, but I should not keep struggling with the direct route. A transfer is more practical. The left can likely reach x = -0.05 m, about 0.55 m from its estimated base, while the right’s current leftward limit appears near x = 0.02 m. One direct-handoff option is for the right to hold the bar top-down at (0.05, -0.10, 1.02) m. The left is already holding the green pepper, so it would first place that in the blue basket, likely reachable near x = 0 m, y = 0.05 m. It could then grasp the gold bar near x = 0 m, y = -0.1 m with an opposing orientation while the right opens. That is manageable but more complex than setting the bar down and regrasping it. For a temporary table placement, I considered x = -0.05 m, y = -0.2 m, or x = 0.05 m, y = -0.2 m. The central area contains the left watch near (0.023, -0.113) m in XY and the middle yellow pepper near (-0.14, -0.16) m. A point at (0.05, -0.28) m would be in front of the watch and appear clear, but the left arm’s reach to x = 0.05 m might be marginal: that is about 0.65 m from its estimated base. A better transfer point may be (-0.05, -0.25) m. The right’s precheck failed at x = -0.04 m, y = -0.038 m, but it might reach x = -0.05 m at y = -0.25 m because the more negative Y position is closer to the base. Moving from the gold bar’s original x = 0.165 m to (-0.05, -0.25) m is an estimated 0.23 m motion, within the target-distance bound, and may pass. The left should reach that point easily. I estimate that (-0.05, -0.25) m is 0.125 m from the middle yellow pepper at (-0.14, -0.162) m and 0.16 m from the left watch at (0.023, -0.113) m, leaving a clear temporary placement area. I’ll set the bar down stably there, then let the left pick it up after placing the green pepper. Only the final object locations matter for the task, so a temporary placement is acceptable. This may add roughly 100 control steps, but there is enough budget. A direct handoff at (-0.05, -0.25, 0.95) m after the pepper placement is another option, though the table transfer seems simpler and more robust. I can stage the motions while avoiding crossed paths. One possible right route is from its current (0.153, -0.038, 1.024) m through (0.05, -0.18, 1.02) m to (-0.05, -0.25, 0.92) m. The left could rise from (-0.335, -0.131, 0.966) m to z = 1.05 m, then travel toward (0, 0, 1.02) m for the blue basket. The right transfer path near (-0.05, -0.25) m and the left path through y = -0.1 to 0 m would have about 0.15 m of Y separation. The right could be near the left’s initial pepper location, so I should coordinate this step by step and lift the left first. I still need to verify the left arm’s reach to the blue basket. A top-down target at (0, 0.02, 1.02) m seems likely to pass: from the estimated left base at x = -0.6 m to x = 0 m is 0.6 m. The rejected right target at x = -0.04 m, y = -0.038 m was about 0.64 m across from its base and missed by about 5 cm, so the left’s blue-basket target may be just within reach. The right’s red basket at x = 0.3 m and the left’s white basket at x = -0.3 m should be easier. A transfer near x = -0.05 m therefore seems feasible for both if Y remains close enough. I’ll explain the change of plan as a limitation of the right arm’s current cross-table configuration and stage the gold bar centrally for the left arm to finish. No motion occurred during the failed precheck, and this was not an execution fault. For the immediate action, I’ll lift the left toward z = 1.05 m while moving the right toward (0.10, -0.18, 1.02) m, about 0.156 m toward the transfer area and likely reachable. I’ll keep both objects held and use 5 control steps.

The right arm has only reached y = -0.073 m, short of its target at y = -0.18 m. The left link6 is at z = 1.022 m rather than the target height of 1.05 m, so both motions need to continue. The 5-step actions seem slow. I could use 10 steps for clear transport, and I also considered 8 steps, but I’ll use 6. I’ll raise the left target to z = 1.08 m to ensure clearance and keep the right target at (0.10, -0.18, 1.02) m. I estimate that both the gold bar’s bottom and the green pepper’s bottom are around z = 0.86 m, safely above the table. The right path from its current XY position of (0.137, -0.073) m toward (0.10, -0.18) m passes near the left watch at approximately (0.023, -0.113) m. With the held bar centered at x = 0.137 m and about 0.1 m long along X, one end may be near x = 0.08 m, leaving about 0.057 m along X from the watch. Could the gripper’s width along Y still cause contact? I estimate the held bar’s bottom at z = 0.86 m and the watch’s top at z = 0.785 m, giving 0.075 m of vertical clearance, which seems safe. The left pepper can continue lifting in clear space.

The basket floor’s front bottom may be at image row 205, corresponding to world y ≈ 0.009 m. Where is the occluded back bottom? The visible back edge of the floor may be around image row 165; at z = 0.75 m, I estimate its world y coordinate as 0.143 m. This gives an estimated floor center at y = 0.076 m. The rim appears to span world y coordinates from -0.04 to 0.13 m, with a center at 0.045 m. A floor-center estimate of y = 0.05–0.08 m seems reasonable, so I initially favor a placement target at x = 0 m, y = 0.06 m. A top-down pose at y = 0.06 m, z = 1.02 m may be near the arm’s reach limit, though a lower pose might be possible. The right arm reached y = -0.02 m, z = 1.02 m earlier, but y = 0.06 m might fail, and the left arm may have similar limits. I could tilt the gripper for placement if needed. The basket’s front interior at y = 0 m may be sufficient. At a link6 target of (0, 0, 1.0) m, I estimate the pepper’s bottom as 1.0 - 0.14 - 0.04 = 0.82 m, which could collide with the rim at z = 0.84 m. Raising link6 to z = 1.06 m would put the pepper’s bottom at 0.88 m, allowing release above the front interior so it drops into the basket. I’ll instead consider a placement pose at y = 0.02 m, z = 1.04 m; the arm may reach it, so I’ll attempt that approach. Is the white basket centered at x = -0.30 m? At image column 190, assuming a floor height of z = 0.75 m gives x ≈ -0.33 m, whereas assuming a rim height of z = 0.84 m gives x ≈ -0.28 m. The inferred x coordinate changes with the assumed depth even though the basket’s actual x coordinate is fixed. Stereo matching of basket corners could refine this estimate. For now, the likely basket centers are x = -0.3, 0, and 0.3 m. I’ll use x = 0 m for the blue basket, -0.3 m for the white basket, and 0.3 m for the red basket. For the immediate action, I’ll move the left arm to the intermediate pose (-0.18, -0.02, 1.08) m and continue the right arm toward (0.10, -0.18, 1.02) m, using 8 control steps.

The left intermediate target at (-0.18, -0.02, 1.08) m failed the precheck with a position error of about 12 mm. I could lower the link6 height to 1.03 m or move the Y target closer to -0.06 m. At a link6 height of 1.03 m, I estimate the held pepper’s bottom at 1.03 - 0.158 - 0.04 = 0.832 m, slightly below the estimated basket rim height of 0.84 m, so crossing the basket could cause contact. However, this intermediate pose is not yet above the basket, so I judge it safe. I’ll use the lower, closer left target (-0.18, -0.06, 1.04) m before continuing. I estimate its distance from the current pose as 0.185 m and expect it to be reachable. The right target will remain unchanged. This failure indicates difficulty reaching high poses with the top-down orientation; placement may require a lower pose or a tilted gripper.

In the high-camera view, the green pepper now appears over the front-right of the white basket at approximately (201, 192) pixels. The left arm has moved to x = -0.217 m, y = -0.08 m, but this is only an intermediate position, not the intended placement. The gold bar appears near (362, 228) pixels, perhaps near the center watch. I estimate its bottom at z = 0.86 m, still clear above the scene. The right arm has reached its transfer approach at x = 0.1 m, y = -0.18 m. I’ll move the gold bar toward the temporary table location at (-0.05, -0.25) m in XY, then descend to place it. I estimate the horizontal move as 0.161 m; reaching x = -0.05 m may pass the precheck at this closer Y position. For the left arm, I’m considering (-0.08, -0.02, 1.02) m from its current (-0.217, -0.08, 1.047) m, an estimated distance of 0.149 m. For the right, I considered (-0.05, -0.25, 0.96) m, descending 0.06 m while moving 0.15 m along X, for an estimated distance of 0.173 m. Although the paths converge, the proposed left and right XY targets are separated by 0.23 m along Y, which I judge safe for simultaneous motion. The lower left target may be reachable and would put the pepper above the front-left of the blue basket. I also considered a right transfer height of z = 0.94 m. With the bar held 0.14 m along local +X, I estimate its center at z = 0.80 m and its bottom at z = 0.79 m, still 0.04 m above the table at z = 0.75 m. A final link6 height of 0.91 m would put the center at 0.77 m and the bottom at 0.75 m. I’ll first move the right arm to (-0.05, -0.25, 1.0) m, an estimated distance of 0.174 m, and then descend to z = 0.916 m for release. For this action, I’ll keep the left target slightly higher at (-0.08, -0.02, 1.04) m to maintain clearance and use 8 control steps.

The left target at x = -0.08 m, y = -0.02 m, z = 1.04 m failed with the gripper top-down. Its X reach limit in this configuration may be around -0.15 m. Is the blue basket’s center at x = 0 m also unreachable for the left arm with this orientation? I could use the right arm for the peppers, since it may reach x = 0 m more easily, but transferring the peppers would be cumbersome. With my estimated left base at x = -0.6 m, the blue basket is 0.6 m away along X, while the available reach at y = 0.02 m may be about 0.55 m. Perhaps the bases are actually at x = ±0.4 m rather than ±0.6 m, and the precheck failures reflect joint limits instead. Changing the gripper orientation might free the wrist and improve reach. I need to understand the kinematics better. The ARX X5 starts with all joint angles at zero and the end effector at a 90-degree Z rotation. Does the top-down 90-degree Y orientation impose a difficult configuration on joint 6? Perhaps the wrist roll is singular, or this top-down orientation with closure along world Y is feasible only in part of the workspace, with cross-table reach limited by the elbow. Tilting the fingers toward world +X could also extend their reach. For placement in the blue basket, I could return the left gripper toward its initial orientation, with the fingers pointing forward along world +Y, and target link6 at (0, -0.15, 0.95) m. The fingers would then extend toward y = 0 m and carry the pepper into the basket. This might avoid the reach difficulty of a high top-down pose. The current grasp closes along world Y; with the initial 90-degree Z orientation, local Y points along world -X. Does that amount to a 90-degree rotation? The pepper would reorient while held. With the fingers horizontal rather than downward, would it rotate or hang sideways? A sideways placement is acceptable because the container task has no orientation requirement. The rotation from the top-down 90-degree Y orientation to the initial 90-degree Z orientation is 2.094 rad, so I would need to execute it gradually. It may be feasible and would let the fingers extend over the basket’s front wall. A 45-degree tilt could be a useful compromise. I should look for a feasible orientation through the precheck before executing motion. One possible left target above the blue basket’s front is (-0.02, -0.07, 1.03) m, with an approximate midpoint quaternion of [0.8165, 0, 0.4082, 0.4082] in wxyz order. The orientation distance from the current top-down pose to that midpoint is 1.047 rad, slightly above the 1 rad command limit. An interpolation fraction of 0.4 would instead give a rotation of about 0.838 rad. I’ll calculate that quaternion. With the fingers partly forward and partly downward, the held pepper would be offset in both directions, so link6 would need a more negative Y coordinate to place the pepper near y = 0.04 m. I am using a grasp contact point 0.14 m along local +X. What world direction does local +X take during this interpolation? At fraction 0.4, the total rotation would be 0.838 rad, or about 48 degrees. Would local +X rotate from world -Z toward world +Y? I’ll use SciPy to calculate the interpolated quaternions and finger directions before choosing the next pose.

Spherical interpolation from the top-down orientation toward the initial orientation tilts local +X toward world +X and +Y while retaining a downward component. The +X component helps the left arm reach toward the blue basket’s center. The same tilt would not help the right arm reach the white basket, but the right is using a transfer point instead. At interpolation fraction 0.5, local +X is (0.333, 0.667, -0.667). A contact point 0.14 m along that axis has a world offset of (0.047, 0.093, -0.093) m. For a pepper-center target of (0, 0.05, 0.88) m over the blue basket, this suggests a link6 target of (-0.047, -0.043, 0.973) m. It is near the failed target (-0.08, -0.02, 1.04) m, but lower and tilted, so it may be reachable. The fingers extend to 0.1576 m along local +X. The held pepper may extend another 0.04 m downward from the contact point, putting its bottom around z = 0.84 m, level with the estimated basket rim. With the object center at z = 0.88 m above an estimated floor center at z = 0.80 m, the 0.08 m drop should allow a stable placement. From the current left link6 position of (-0.217, -0.08, 1.047) m, that proposed target is about 0.184 m away. However, the midpoint orientation requires a 1.047 rad rotation, exceeding the 1 rad command limit. I’ll instead use interpolation fraction 0.4, with quaternion approximately [0.812, 0, 0.4799, 0.3321] in wxyz order and a rotation of 0.838 rad. Its local +X direction is (0.319, 0.539, -0.779), giving a contact offset of (0.045, 0.075, -0.109) m. For a pepper-center target of (-0.005, 0.04, 0.88) m, the corresponding link6 target is (-0.05, -0.035, 0.989) m. I’ll use (-0.05, -0.035, 0.99) m with this orientation; it may be reachable. The right transfer target remains (-0.05, -0.25, 1.0) m with its top-down orientation. Both link6 targets are near x = -0.05 m, but they are separated by 0.215 m along Y and have similar heights, which I judge safe. I’ll use 8 control steps to rotate and move the left arm while moving the right toward the transfer point. Either precheck may still fail, in which case I’ll adjust the target. I need to be cautious while rotating the pepper near the white basket’s rim. It may currently be over the white basket at approximately (-0.217, -0.08) m in XY. With contact 0.14 m downward from link6, I estimate its center at z = 0.907 m and its bottom at z = 0.867 m, above the estimated rim at z = 0.84 m. The tilted contact offset is (+0.045, +0.075, -0.109) m relative to link6. The link6 target lowers by 0.057 m to z = 0.99 m, and the estimated contact height changes from 0.907 m to 0.881 m. The pepper could dip during interpolation, but these estimates suggest clearance above the rim. I’ll try this motion.

The arms appear close in the high-camera view. Does the white section of the left arm cross the right arm? The left arm extends toward approximately pixel (320, 160), and the right toward (230, 210). They overlap in the image but may be separated along Y or Z. The measured link6 positions are (-0.154, -0.061, 1.028) m on the left and (-0.016, -0.237, 1.003) m on the right. I estimate their separation as 0.226 m, which I judge safe, though the upper arm bodies could still be close. No collision has been reported. I considered continuing the targets for 8 steps. The right arm’s XY position, (-0.016, -0.237) m, is close to its transfer target of (-0.05, -0.25) m. The left orientation is still progressing, and I’ll keep its position target at (-0.05, -0.035, 0.99) m. The right can now descend toward (-0.05, -0.25, 0.916) m while the left continues its tilt. I estimate the right target distance as 0.093 m and judge the table area clear. Using a 0.14 m offset below the right link6, I estimate the held bar’s current center height as 1.003 - 0.14 = 0.863 m and its bottom at about 0.85 m. At link6 height 0.916 m, I estimate its center at 0.776 m and its bottom at 0.765 m. Perhaps a final link6 height of 0.906 m would let the bottom rest at 0.755 m. Should I instead use 0.916 m and then release? I estimate the packaging thickness as 0.02 m; with a grasp center at 0.775 m, would the bottom be at 0.765 m? The table is estimated at 0.75 m, and another bar-height estimate is 0.015 m. A bottom height of 0.765 m would leave it floating 1.5 cm above the table, which seems acceptable for a short drop on release. I’ll use 0.916 m as the release height. For now, I’ll descend the right arm while the left completes its tilt, using 6 control steps.

In the high-camera view, the green pepper appears directly above the blue basket near pixel (270, 170), perhaps inside its front-left rim. The gold bar appears near pixel (277, 307), behind the right gripper at the table transfer point. I’ll release the gold bar and then retract the right arm upward, while the left finishes its placement pose before releasing the pepper. I considered opening the right gripper and continuing the left motion for 2 steps, followed by lifting the right arm and opening the left gripper. The right link6 is at z = 0.923 m. I estimate the bar’s center at z = 0.783 m and its bottom at z = 0.773 m, so a drop of about 2 cm seems acceptable. The left arm has not reached its final target. Its measured quaternion is [0.796, -0.002, 0.558, 0.233], compared with the desired [0.812, 0, 0.480, 0.332] in wxyz order; I estimate the orientation difference as 0.19 rad. Its position is (-0.112, -0.048, 1.014) m, about 0.067 m from the target (-0.05, -0.035, 0.99) m. The pepper may still be near the blue basket’s front-left edge. Starting from x = -0.112 m, I am considering a +0.04 m Y contact offset as giving approximately -0.07 m, though I remain unsure whether it is sufficiently inside along X. I estimate the basket’s X span as [-0.125, 0.125] m and the pepper’s radius as 0.04 m; a pepper position around x = -0.07 m after reaching the target would be better. I should finish the left target before releasing it. For the immediate action, I’ll open the right gripper while continuing the left toward its target for 3 steps.

The gold bar has been released and appears stable on the table. The left arm has not fully reached its placement target, but the green pepper appears near pixel (280, 177) in the high-camera view, inside the blue basket’s left edge. I could continue the left arm toward its target for about 4 steps before releasing the pepper. For the right arm, I considered lifting to z = 1.03 m and moving away toward (0.15, -0.25, 1.03) m, or first lifting vertically to z = 1.05 m to clear the staged bar. I’ll use the vertical clearance target (-0.048, -0.249, 1.04) m, a 0.117 m lift, which looks safe. Before deciding whether the left arm needs more motion, I should check the pepper’s estimated position from the current grasp geometry. With the left quaternion [0.806, -0.002, 0.523, 0.278] in wxyz order, I estimate the local +X direction as (0.323, 0.578, -0.751). Using a contact point 0.14 m along that direction gives (-0.091, -0.043, 1.006) + 0.14 × (0.323, 0.578, -0.751) = approximately (-0.046, 0.038, 0.901) m for the green pepper’s center. Its x coordinate is 0.046 m left of the blue basket center, whose estimated XY position is (0, 0.05) m. With a basket half-width of 0.125 m and a pepper radius of 0.04 m, I judge the pepper to be inside the basket’s footprint. Its estimated bottom height is z = 0.861 m, above the rim at z = 0.84 m. I can therefore release the pepper now without reaching the exact target. Although the skill asks me to aim as close to the center as possible, this slightly leftward position looks acceptable. I expect it to drop into the blue basket near x = -0.046 m, y = 0.038 m. I’ll hold the left arm at its current measured pose and open its gripper while lifting the open right gripper to z = 1.04 m. I considered a 3-step release and lift; the simultaneous actions look safe. Afterward, I’ll retract the left arm upward and away, then verify that the pepper remains in the basket.

The green pepper is stable in the blue basket, so one of the eight objects is sorted. The gold bar is stable at the transfer point. The left arm still needs to put the purple and staged gold chocolates into the white basket. The red chocolate, estimated at x = 0.423 m, may be too far for a direct left-arm pickup, so it may need another right-to-left transfer. The two yellow peppers at x ≈ -0.27 m and -0.14 m belong in the blue basket; the left arm may be able to place them using the tilted orientation. The watches at x ≈ 0.023 m and 0.314 m belong in the red basket and can be handled by the right arm. The right gripper is open near the staged gold bar at (-0.046, -0.25, 0.972) m. The left gripper is open and tilted above the blue basket at (-0.091, -0.043, 1.006) m. I can next have the left pick up the staged gold bar and place it in the white basket while the right picks up the right-side watch and places it in the red basket. The right could instead handle the red chocolate next, but I’ll proceed toward the watch. The right arm’s move from the transfer point to the watch near (0.314, -0.093) m in XY is about 0.39 m, so it needs intermediate targets. I initially considered retracting upward to z = 1.05 m, moving to (0.15, -0.20, 1.03) m over about 0.22 m, then moving to (0.314, -0.093, 1.02) m over about 0.20 m. The left could move directly above the gold bar at (-0.048, -0.249, 1.02) m. Is that move about 0.25 m? Its displacement is approximately (0.043, -0.206, 0.014) m, giving about 0.211 m, within the limit. Returning from its current quaternion [0.806, -0.002, 0.523, 0.278] to the top-down quaternion [0.707, 0, 0.707, 0], both in wxyz order, gives an estimated dot product of 0.570 + 0.370 = 0.940 and an orientation distance of 0.695 rad, within the 1 rad limit. I could move the left directly above the gold bar while rotating and move the right to (0.15, -0.20, 1.05) m. The proposed gripper positions would be about 0.205 m apart, with the left at y = -0.249 m and the right at y = -0.20 m. However, the right starts at nearly the same X coordinate as the left’s gold-bar target. Their current separation is about 0.21 m, with heights of 0.972 m on the right and 1.006 m on the left. Their paths could cross near x = 0 m, y = -0.2 m as the left approaches from the northwest and the right departs eastward. That might be acceptable, but the fingers could come close at the start. A better sequence is to move the right away to (0.15, -0.20, 1.05) m while the left moves to an intermediate pose left of the gold bar at (-0.18, -0.20, 1.04) m. Their final separation would be about 0.33 m, and the paths would diverge: the left moves leftward and toward more negative Y, while the right moves rightward and upward. After that, the left can approach (-0.048, -0.249, 1.02) m and the right can approach the watch at (0.314, -0.093, 1.02) m. I estimate the immediate moves as 0.179 m for the left and 0.205 m for the right. I’ll use 8 control steps, restoring the left’s top-down orientation and keeping both grippers open. At the left intermediate height of 1.04 m, I estimate its downward fingertips at z ≈ 0.88 m, above the gold bar’s estimated top at 0.78 m. The staged gold bar appears horizontal along the image X direction in the high-camera view, near (290, 306) pixels; another estimate is (280, 306). Its original long axis also appeared along X. It appeared vertical in the right wrist image because that camera’s top-down orientation maps world X along optical Y. The left can use the same top-down orientation and close along world Y across the bar’s short dimension. The bar may have shifted slightly after release. In obs_000165, I estimate its center at (300, 180) pixels in the right wrist view and (291, 306) pixels in the high view, suggesting world XY near (-0.05, -0.25) m. Matching the logo between those views could refine its position. For now, the release position of (-0.048, -0.249) m is a reasonable grasp estimate. I am uncertain whether the original bar-center offset from the end effector was about -0.001 m. Using the previous adjusted grasp position of (0.166, -0.181) m and the release position, I estimate the staged bar center near (-0.049, -0.250) m. The left grasp target can be (-0.048, -0.249) m in XY with link6 at z = 0.923 m, as for the right-arm grasp. The right watch’s case is estimated at (0.314, -0.093, 0.784) m. I still need to choose whether to grasp its case or band. Is the band loop vertical in the world? The high view shows a thin elliptical ring with the white case toward the upper right. In the wrist view from obs_000061, the loop appears circular and upright, with the case at the upper right. It may be a watch toy standing with its band loop vertical, though I am unsure whether these watch objects normally lie flat with a circular loop standing vertically. The wrist image suggests the ring plane is roughly parallel to the image plane. With an optical forward direction having a downward component of 0.866, that image plane is somewhat vertical, so a vertical loop remains plausible. A top-down grasp of the white case could work if it is at the top of the loop at z = 0.784 m above the estimated table at z = 0.75 m. A link6 height of 0.92 m with contact 0.14 m along local +X gives contact around z = 0.78 m. The fingers would close along world Y; I estimate the case width along Y at 0.02 m and the band-loop diameter at 0.05 m. A case grasp directly above (0.314, -0.093) m at link6 z = 0.924 m would put the fingertips near z = 0.766 m. The estimated 0.08 m open width should accommodate an outer loop diameter of about 0.055 m. Alternatively, the right could grasp the band with the same closing direction, near ring-center XY coordinates (0.30, -0.10) m and link6 z = 0.91 m. I should distinguish the ring center from the case. From the stereo case estimate, the ring center may be around (0.302, -0.103, 0.768) m, with the case to its right and above. The high-view ring center at (457, 235) pixels versus the case at (462, 230) pixels suggests a world difference of approximately (-0.01, -0.01, -0.014) m at z ≈ 0.77 m. Another ring-center estimate is (0.302, -0.103, 0.77) m. A grasp across the outer band near its top might target contact at (0.31, -0.10, 0.78) m with link6 at z = 0.92 m. I’ll inspect the watch again when the right arm is closer. For now, I’ll execute the left intermediate move and rotation while moving the right away from the transfer point.

The gold bar looks well positioned near pixel (291, 305) in the high-camera view. The right arm is moving toward the watch, which is visible at the left edge of the right wrist image because the camera’s optical X direction is opposite world Y. I’ll continue toward the same targets for another 8 control steps.

The staged gold bar is not visible in the left wrist view. The left link6 is at XY coordinates (-0.173, -0.189) m, while the bar is estimated near (-0.048, -0.249) m. Could the bar be to the right in the image? With this top-down orientation, optical X is opposite world Y, so the relative Y offset of -0.06 m may put it toward the image’s right side. The purple bar is visible at the bottom-right; the gold bar may instead be below the image boundary. I should move the left gripper above the gold bar. I’ll target the left link6 at (-0.048, -0.249, 1.02) m, about 0.139 m away, and approach the right-side watch at (0.314, -0.093, 1.02) m, about 0.194 m away. Both approach paths appear safe, so I’ll use 8 control steps with the grippers open. I considered using the nominal right top-down quaternion [0.707, 0, 0.707, 0] in wxyz order, but I’ll hold its current quaternion [0.704, 0.007, 0.71, 0.006] to avoid a small orientation adjustment. The left gripper is already pointing directly downward.

Is the right watch partially above the wrist image, around pixel (450, -50)? I appear to see two watches in the right wrist view. I identify the partial ring at the top-left as the target right watch, estimated at world XY coordinates (0.314, -0.093) m, and the ring near the bottom-center as the left watch, estimated at (0.023, -0.113) m. Could the camera be looking back toward that second watch? The right link6 is currently at x = 0.241 m, y = -0.145 m. The camera’s optical X direction is opposite world Y, so the right watch’s relative Y offset of +0.052 m projects leftward, consistent with the top-left ring. The left watch has relative offsets of x = -0.218 m and y = +0.032 m; I would expect it farther down, and it appears near the bottom-center. I’ll move the right gripper toward XY coordinates (0.31, -0.10) m to center it over the right watch. The gold bar is near the top of the left wrist view, around pixel (330, 50), and should become centered as the left gripper finishes positioning and later descends. I’ll continue toward both existing approach targets for 6 control steps.

The right watch’s ring now looks fairly flat. It may be a circular band lying horizontally on the table, viewed by the angled wrist camera, with the white case on the right at roughly the same height. Its apparent diameter is about 110 pixels. I initially estimate the grasp center at (320, 170) pixels, with the fingers below it. I should descend until the ring center is near image y = 330 pixels. With link6 at z = 1.02 m and the ring at an estimated z = 0.77 m, the ring is 0.25 m along local +X and should project near y = 150 pixels, which matches reasonably well. At link6 z = 0.91 m, the ring would be 0.14 m along local +X and project near y = 330 pixels. Looking more closely, the ring center may actually be at (288, 170) pixels, with the case at (320, 135). The gripper closes horizontally in the image, along world Y, so a grasp across the band’s diameter should center on image x ≈ 290 rather than 320. Optical X is opposite world Y. Does the ring’s position left of image x = 320 imply a positive relative local Y value, perhaps about 0.000? Moving the end effector along positive local Y would reduce the object’s relative local Y and move its image rightward. Since local Y aligns with world Y, I could increase the right end effector’s Y coordinate. My first correction estimate is +0.006–0.008 m, moving from the measured y = -0.101 m toward y = -0.093 m, which was also the earlier case-position estimate. Could the ring center instead be at world y = -0.11 m? Using an estimated camera depth of 0.17 m, the 30-pixel horizontal offset gives local Y = -(u - 320) × depth / f = 30 × 0.17 / 397 = 0.0128 m. That suggests moving the end effector +0.013 m along Y, to about y = -0.088 m. Where would the case lie relative to that grasp? I could use y = -0.088 m to center a grasp across the band. The vertical image position also bears on the world X estimate. Perhaps the target should be x = 0.30 m rather than 0.31 m. The head-view ring center at (456, 235) pixels suggested world x ≈ 0.30 m and y ≈ -0.11 m, while the case was estimated at x = 0.314 m, y = -0.093 m. The current end effector at x = 0.31 m is approximately above the case. A whole-ring grasp might use x = 0.302 m, y = -0.108 m, but that conflicts with the wrist-based Y correction to -0.088 m. Triangulating the ring center from the current head and wrist views could resolve this. A possible correspondence is the bottom-band midpoint at head pixel (456, 239) and wrist pixel (290, 220), but matching it is difficult. I already triangulated the more distinctive case center. Perhaps the ring center could be inferred relative to the case using the wrist view and its geometry, but exact centering may not be necessary: the estimated open gripper width is 0.08 m, the ring diameter is 0.05 m, and an offset of about 0.01 m may be acceptable. If I retain the right XY target at (0.31, -0.10) m, the approximately 30-pixel ring offset at 0.17 m camera depth corresponds to about 0.013 m. That is within the estimated 0.08 m finger gap and 0.025 m ring radius. The fingers might push the ring toward the center during closure and grasp it. I’ll descend straight first and inspect the alignment before closing. The gold bar’s center in the left wrist view is around (300, 150) pixels, and its intended contact row after descent is also y = 330 pixels. A left grasp height of z = 0.923 m seems suitable. I’ll first lower both link6 targets to z = 0.94 m for 4 control steps, then consider z = 0.923 m for 3 steps. I considered a right watch grasp height of 0.93 m instead of 0.923 m because the case top is estimated at 0.784 m and the ring top at 0.78 m. However, link6 at 0.92 m would put the contact at 0.78 m, so 0.923 m still seems suitable. The gold bar’s estimated table-level height of 0.77 m also supports a 0.923 m grasp height. For this action, I’ll keep both grippers open and lower them to 0.94 m, retaining the right XY target at (0.31, -0.10) m.

The right watch’s ring center appears at (285, 215) pixels, 35 pixels left of the closing center. The gold bar in the left wrist view appears centered at (290, 180) pixels, 30 pixels left of the closing center. Should I make small world-Y corrections for both? With the left end effector at y = -0.249 m, moving it about +0.01 m along Y should move the bar’s image 30 pixels rightward. During the original right-arm grasp, I needed a target of y = -0.182 m from a measured y = -0.181 m, when the bar appeared to the right at image x = 345 pixels. Has the bar rotated 180 degrees during transfer? Am I seeing the reverse side of the gold package at the top of the left wrist view, or its left edge? Those interpretations remain uncertain, but I can still correct the visible offset. I initially considered a left Y correction of +0.008 m to y = -0.241 m and a right correction of +0.010 m to y = -0.089 m. For the right ring center at image x = 285 pixels, a +0.012 m correction seems more appropriate. I’ll use final Y targets of -0.087 m for the right and -0.240 m for the left. The ring’s vertical image center is around y = 215 pixels. Will lowering link6 to z = 0.923 m bring it near image y = 330 pixels? If the ring center is actually at world z = 0.77 m, the current right link6 height of 0.974 m gives a distance of 0.204 m along local +X and a predicted image y of about 214 pixels. At link6 z = 0.923 m, that distance would be 0.153 m, giving image y ≈ 300 pixels. For the gold bar, the current left link6 height of 0.975 m gives a distance of 0.205 m from an estimated top height of 0.77 m and a predicted image y of 184 pixels. At z = 0.923 m, the distance would be 0.153 m and the predicted image y about 296 pixels. A final height of 0.916 m might bring it near image y = 330 pixels, but the earlier right-arm gold grasp worked at 0.923 m. Is the watch-band loop upright? It currently appears circular, about 140 pixels tall and 150 pixels wide, with the white case at the upper right. Its top is near image y = 150 pixels and its bottom near y = 290 pixels. At link6 z = 0.923 m, it may appear about 200 pixels tall with its center near y = 330 pixels. I am unsure of the exact pad positions, but the open inner edges appear near image x = 110 and 520 pixels, giving a 410-pixel gap. The ring’s current outer width is about 150 pixels and may grow to roughly 220 pixels at the final height, so it should fit. Closure along world Y should pinch the outer band. I’ll target the left link6 at (-0.048, -0.240, 0.923) m and the right at (0.31, -0.087, 0.923) m, keeping both grippers open. I considered 2 control steps for this approximately 0.053 m move, but those might produce only about 0.03 m of actual motion and require another step. I’ll use 3 steps.

The right gripper’s opening command is 0.898 despite the requested gripper_closed value of false. It was 1 before and had remained there for many steps, so this is unexpected. Could contact with the watch or red basket have affected the interpolation? Perhaps it is controller lag, or the controller changes the opening dynamically during grasping. It could also be interpolation following an earlier open command. The reported value is the latest interpolated opening command and can differ from the requested endpoint, but I still do not know why it changed here. Could contact have caused slipping? In the high-camera view, the watch remains at approximately (457, 232) pixels with no apparent movement, and the right fingers are near it. I also considered whether the precheck affected interpolation, but the action did execute. I do not consider this discrepancy critical for the next motion. The right watch ring is centered between the pads at approximately (315, 280) pixels. The left gold bar is centered at approximately (320, 220) pixels, but the left link6 height is still z = 0.94 m rather than the target 0.923 m. It may need 3 more steps. The right link6 is at z = 0.939 m; at the target height of 0.923 m, I expect the ring’s contact center near image y = 330 pixels. Another 2 steps may suffice. Could the right fingertips be touching the table? At link6 z = 0.939 m, I estimate their height at 0.781 m, near the watch case’s estimated top at 0.784 m. The open finger is near the band, which looks acceptable. At the final link6 height of 0.923 m, I estimate the fingertips at 0.765 m, leaving 0.015 m of clearance above the table at 0.75 m. I’ll continue toward the same grasp targets for 2 steps with both grippers commanded open.

The right gripper’s opening command has decreased from 0.898 to 0.709, about 0.19 over 2 control steps, even though I explicitly requested gripper_closed = false. Could contact be forcing the gripper closed? The reported opening is the native controller’s latest interpolated command, not a measured finger gap, so that explanation is uncertain. I do not know why an open request would produce 0.709. Perhaps target validation changed the gripper request, contact triggered automatic closure, or the controller is interpolating toward a previous closed command retained in memory. Collision-related interpolation is another possibility. I checked the last robot_act request, and the right gripper was definitely commanded false. Reversed boolean semantics do not seem to explain it, since an earlier false request opened the gripper from 0.208 to 1. The cause remains unresolved, although the reported command suggests closure is already progressing. The right fingers now appear to contact the watch band on both sides, with the left pad on the band and the right pad near the case. The ring is centered and looks ready for closure. The gold bar is also between the left pads. I’ll command both grippers closed for 3 control steps while holding their current poses.

The right watch has shifted in the high-camera view from (457, 232) to (449, 236) pixels beneath the gripper, suggesting that closure squeezed and displaced it. In the wrist view, the band appears folded or rolled, with the case vertical between the pads. The right opening command is 0.02, near closed, so the gripper may be holding a thin strap or the case. I should verify this with a small 0.03 m test lift. The left opening command is 0.329, and the pads appear to contact the gold bar. I’ll test-lift both arms for 3 control steps, aiming for a left link6 height of about 0.96 m and a right height of 0.955 m while keeping their orientations steady. If the watch is securely held, it should move with the right gripper.

The right watch appears lifted near the gripper at about (455, 224) pixels in the high-camera view. The ring was originally at (457, 232), moved to (449, 236) after closure, and appears near (457, 224) after the lift, an upward shift of 8 pixels from its original position. This indicates that it moves with the gripper. The band remains stable relative to the wrist camera, with the case held vertically. The gold bar also stays fixed in the left wrist view; in the high-camera view it is near (280, 300), compared with its previous row of 306, an upward shift of 6 pixels. Both grasps look secure. The left link6 is at (-0.049, -0.241, 0.958) m, holding the gold bar top-down. The white basket is estimated at x = -0.3 m, y = 0.05 m and should be reachable by the left arm. I could lift to z = 1.04 m and approach through (-0.22, -0.15, 1.04) m, then perhaps use a top-down pose at (-0.30, -0.03, 1.00) m. The basket’s front interior may be near y = 0 m. A tilted placement like the green pepper’s is another option. At interpolation fraction 0.4, the contact offset has components of +0.045 m along world X and +0.075 m along world Y. For a gold-bar center target at (-0.30, 0.06) m in XY, a link6 pose at (-0.345, -0.015, 0.99) m would put it near the basket center and should be easy for the left arm. However, the white basket is close enough that a top-down placement should also be feasible. A target at (-0.30, 0.03, 1.02) m likely remains reachable: with the left base estimated at x = -0.6 m, the X difference is only 0.3 m. The right arm previously reached x = 0.15 m, y = -0.02 m, z = 1.02 m, which also supports this expectation. I’ll use a top-down placement target of (-0.30, 0.02, 1.02) m. With the bar center about 0.14 m below link6, I estimate its center at z = 0.88 m and its bottom at z = 0.87 m, above the rim, before release onto the basket floor. The route from approximately (-0.05, -0.24) m to (-0.3, 0.02) m in XY passes left of the blue basket and should avoid the green pepper inside it. At a transport height of z = 1.04 m, I estimate the gold bar’s bottom at z = 0.89 m, providing clearance. The right watch belongs in the red basket, estimated at x = 0.3 m, y = 0.05 m. Both objects can travel toward their baskets simultaneously because the left path stays on the negative-X side and the right path on the positive-X side, without crossing. A right placement target of (0.30, 0.02, 1.02) m is about 0.125 m from the measured pose (0.31, -0.087, 0.954) m, but I should first lift to z = 1.04 m. I considered an intermediate pose at (0.30, -0.02, 1.03) m, followed by perhaps (0.30, 0.05, 1.02) m. For the left arm, the target (-0.30, -0.02, 1.04) m is about 0.341 m away, exceeding the 0.25 m command limit. I’ll instead use the intermediate pose (-0.20, -0.16, 1.04) m, which I estimate is 0.174 m away, before continuing to (-0.30, 0.02, 1.02) m. The right intermediate target will be (0.30, -0.02, 1.04) m. I initially considered 8 control steps for these motions before final placement. The watch grasp may be fragile, with an opening command of 0.027, so I’ll keep its orientation steady. At right link6 z = 1.04 m, a grasp contact 0.14 m along local +X would be at z = 0.90 m. The band may extend another 0.04 m downward to z = 0.86 m, still above the estimated red-basket rim at z = 0.84 m. For the immediate action, I’ll use 6 control steps toward left (-0.20, -0.16, 1.04) m and right (0.30, -0.02, 1.04) m, keeping both grippers closed.

In the right wrist view, the watch band appears to be dragging near the red basket edge, but the case remains held. In the high-camera view, the band is near pixel (465, 213), close to the red basket’s front wall; this looks acceptable, but I need to lift it farther. I considered continuing toward the same transport targets for 8 control steps. The left gripper still holds the gold bar, which has moved to approximately pixel (265, 278) in the high-camera view. I’ll continue toward the same targets for 6 control steps, lifting and advancing both objects.

The right gripper’s opening command has changed from 0 to 0.098 while it is still commanded closed; perhaps contact forces are involved. The held watch band appears to have changed orientation, but it still looks secure. In the wrist view, the red basket rim is on the left, the band is near the center, and the case is below it. Could the watch be contacting the front wall? In the high-camera view, the watch appears near (465, 194) pixels, while the basket’s front wall is around image row 200. That suggests the watch is inside the front edge. Continuing toward the previous right target at y = -0.02 m from the measured y = -0.042 m would move the watch farther into the basket. I could use a final right link6 target of (0.30, 0.04, 1.02) m from the current (0.303, -0.042, 1.016) m. I estimate that move as 0.082 m and expect it to be reachable. The left target of (-0.30, 0.02, 1.02) m is about 0.212 m from its measured position of (-0.195, -0.164, 1.036) m, within the position command limit. The left wrist view shows the purple chocolate and a yellow pepper near the gold bar’s path. In the high-camera view, the gold bar appears over the white basket’s front edge at approximately (212, 234) pixels, with the yellow pepper below. Moving toward the white basket at x = -0.3 m, y = 0.02 m should carry the gold bar above it with clearance. The purple bar appears near (127, 289) pixels, with estimated world XY coordinates of (-0.39, -0.206) m. With the left link6 currently at x = -0.195 m, y = -0.164 m, I estimate the gold bar’s bottom at z ≈ 0.88 m, about 0.1 m above the purple bar, which seems safe. I considered 8 control steps. I’ll instead use 6, keeping both grippers closed, with the left target at y = 0.02 m, z = 1.02 m and the right target slightly higher at y = 0.04 m, z = 1.03 m.

The right target at y = 0.04 m, z = 1.03 m failed the precheck with about 20 mm of position error, so neither arm moved. I could try a lower, closer target at y = 0 m, z = 1.0 m, or tilt the watch forward. I am no longer confident that the watch is over the red basket’s interior. With the gripper top-down, I estimate the case contact center at (0.303, -0.042, 0.876) m; the band may extend toward y = 0 m. Releasing at the current y = -0.042 m could drop it onto the front wall. The watch appears at high-camera pixel (465, 194). Could that be over the rim or floor? I had estimated the front top around image row 190, but the front wall appears to span rows 184–211 and the interior floor rows 155–190. The watch at row 194 therefore seems to be over the front wall rather than inside. I should move it at least +0.04 m along world Y toward the center. If the top-down reach is limited, I can tilt forward as I did with the green pepper. Ideally, local +X would point toward world +Y without a world +X component; perhaps a rotation about world Y, as considered earlier, could do that. Spherical interpolation from the top-down orientation toward the initial orientation instead gives local +X positive world X and Y components and a negative Z component. The positive X component would move the watch rightward within the red basket, which seems acceptable. At interpolation fraction 0.4, local +X is approximately (0.319, 0.539, -0.779), and the contact offset is (0.045, 0.075, -0.109) m. To put the watch center at (0.30, 0.05, 0.89) m, I could target right link6 at (0.255, -0.025, 0.999) m with quaternion [0.812024, 0, 0.479925, 0.332099] in wxyz order, the same tilted orientation used for the green pepper. From the current right position, (0.303, -0.042, 1.016) m, I estimate a target distance of 0.052 m. The top-down-to-tilted rotation is about 0.838 rad, within the 1 rad limit. Checking against the current quaternion [0.704, 0.007, 0.71, 0.005], my dot-product estimate is 0.572 + 0.341 + 0.0017 = 0.915, again giving about 0.838 rad. This tilted placement may be reachable, while the left can continue toward its unchanged white-basket target. However, tilting immediately could drag the watch across the red front wall, whose world Y coordinate may be around -0.03 m. The estimated watch center would move rearward by +0.09 m and upward by only 0.014 m. The rim is estimated at z = 0.84 m, and the watch bottom may currently be at z = 0.83 m. The case bottom appears near wrist-image row 400 and could be below the rim. Another estimate puts the band bottom at z = 0.84 m, just level with the rim, while the case contact is at z = 0.876 m. I should lift before tilting. I first considered raising right link6 to z = 1.08 m, or lifting about 0.04 m to z = 1.056 m at its current X and Y coordinates. I’ll use (0.303, -0.042, 1.06) m, a vertical target change of 0.044 m, while keeping the right orientation steady and the watch held. I considered 3 control steps, but will use 6 steps for this lift while the left continues to its final white-basket target. Then I can tilt the watch forward for placement with better wall clearance.

The watch ring now appears near (475, 177) pixels in the high-camera view. Is it clearly inside the red basket’s front area? I estimate the interior at image rows 150–195, so it looks inside. Another estimate puts the ring at (477, 178) pixels, within the red basket’s image bounds of x = 385–510 and y = 140–210 pixels. With the right link6 at (0.303, -0.043, 1.059) m, I estimate the case’s grasp contact at z = 0.919 m, the ring bottom perhaps at z = 0.86 m, and the rim at z = 0.84 m. The opening command is 0.135. The case appears held, although I still wonder whether the band lies across the front. Overall, the ring looks inside the basket’s footprint near the front-right. Releasing here seems safest, without the additional tilt. I expect it to fall about 0.08 m to the floor. The gold bar appears near (209, 204) pixels in the high-camera view. Is it over the white basket’s front wall? I estimate the white interior at image rows 150–200, so the bar at row 204 still appears at the front edge, near the bottom of the wall rather than inside. The left link6 is at (-0.241, -0.089, 1.026) m, and I estimate the gold bar’s contact center at y = -0.089 m. The white basket’s front interior may be near world y = -0.02 m. I’ll continue the left arm toward (-0.30, 0.02, 1.02) m with the bar held. I’m considering 3 steps to open the right gripper at its current pose while the left moves, then I’ll verify whether the watch falls inside the red basket.

The watch landed outside the red basket. In the high-camera view, it is near (465, 217) pixels, in front of the basket, whereas it appeared inside at (475, 177) while held. Perhaps the band caught on the gripper and was pulled forward as the fingers opened, or perhaps it was already outside the front wall and its height made the overhead projection misleading. In the right wrist view from obs_000232, the ring is around (400, 160) pixels, to the right of the red basket, which occupies the left half of the image. The middle watch is visible near the bottom. I am unsure how that image-side relationship maps to the world position, so I should use stereo to locate the dropped watch. Native success is still false, and I need to regrasp it and place it truly inside. Another estimate puts the dropped watch at high-camera pixel (466, 216), with its table-level height around z = 0.75–0.78 m. Before grasping, it was at (457, 232); its current image row is 16 pixels farther back, but the basket’s front wall is around row 210, leaving the ring center at row 216 just outside. The change from the held position at (475, 177), with z ≈ 0.9 m, to the dropped position at (465, 217), with z ≈ 0.77 m, could largely result from height: lowering it shifts its projection downward by about 40 pixels even if its world XY position stays the same. I now think it landed at the same world y ≈ -0.043 m, outside the basket’s front. I released too early based on the overhead image. I should move it farther back, to at least y = 0.04 or 0.08 m, using the tilted placement I had considered. The same issue applies to the gold bar. It appears near (208, 203) pixels while held at z ≈ 0.88 m. If released down to z ≈ 0.77 m at its current y = -0.055 m, I expect its image position to shift down about 30 pixels to row 233, outside the white basket. I should move the left arm toward y = +0.05 m or tilt the gripper. Even the previous top-down target at x = -0.30 m, y = 0.02 m may not be far enough inside. What would the gold bar’s image row be at y = 0.02 m, first at z = 0.88 m and then at z = 0.77 m? Perhaps the latter would be around row 208; I should calculate it rather than rely on its held projection. I need to check the eventual floor-level footprint against the basket interior. The white basket’s visible inner floor may be a quadrilateral spanning roughly x = 151–238 and y = 151–196 pixels, with the front wall’s top around row 190. Those boundaries remain tentative. At z = 0.76 m, I want the released object’s center inside the approximate floor polygon, around x = 150–235 and y = 160–195 pixels. I’ll project the candidate gold-bar position (-0.30, 0.05, 0.76) m and the watch position (0.30, 0.08, 0.77) m. Their world Y targets probably need to be around 0.08–0.1 m to land inside. The earlier inverse projection placed the floor center at y = 0.102 m for image row 176 and z = 0.75 m, so I now take the basket floor center to be near y = 0.1 m rather than 0.02 m. The rim-center estimate of y ≈ 0.03 m came from a different height. I should target floor-level Y coordinates of 0.08–0.10 m. I believe a top-down reach to y = 0.1 m is unavailable, so I need to tilt the fingers forward along world +Y for basket placement. The green pepper was released with left link6 XY coordinates (-0.091, -0.043) m and a tilted orientation at interpolation fraction about 0.45. I estimate its local +X direction as (0.326, 0.60, -0.72), with a contact offset of +0.084 m along world Y, giving an object Y coordinate near 0.04 m. It ended up contained near high-camera pixel (330, 176), perhaps with an actual floor-level y ≈ 0.06 m. It is toward the front of the blue basket but remains inside. For the gold bar, I should aim for an object-center Y coordinate of 0.07–0.09 m, using interpolation fraction 0.4 or 0.5 and link6 y near 0 m. I can use a similar approach for the watch. A tentative common floor-center target is x = ±0.3 m, y = 0.08 m for the outer baskets. I suspect native container success checks whether the object lies within a bounding box, perhaps with Y bounds of [-0.02, 0.18] m, in which case y = 0.05 m might suffice. That is only a hypothesis. Since the green pepper at y ≈ 0.04 m is contained, I’ll use y = 0.08 m as the next object target. I still need the watch’s actual dropped position. The right link6 was at (0.303, -0.043, 1.059) m when it released the watch, but I do not know the held case’s X and Y offsets from link6. In obs_000232, the white case may be near high-camera pixel (472, 216) and right-wrist pixel (440, 170). I’ll triangulate those estimated matching case centers to recover its XYZ position. The left arm can keep holding the gold bar safely while the right recovers the watch. Its current link6 position is (-0.262, -0.055, 1.021) m. For a tilted orientation at interpolation fraction 0.4, with quaternion approximately [0.812, 0, 0.480, 0.332] in wxyz order, I estimate the contact offset as (0.045, 0.075, -0.109) m. A desired gold-bar center of (-0.30, 0.08, 0.89) m, about 0.14 m above the floor, therefore suggests a link6 target of (-0.345, 0.005, 0.999) m. I estimate the orientation change as 0.838 rad and the position distance as 0.102 m. This looks comfortably within the left arm’s workspace, and I expect the precheck to pass. Releasing from an estimated center height of z = 0.89 m would let the bar drop to the floor at z ≈ 0.76 m while keeping y = 0.08 m, inside the white basket. I could move the left arm to that tilted placement pose while the right approaches the watch, whose ring center may be near world XY coordinates (0.31, -0.04) m. The right gripper is currently open at (0.303, -0.043, 1.059) m, above the dropped watch. Before descending or repositioning it for another grasp, I’ll triangulate the case and project the candidate floor-level placement points. This next call will only run calculations; it will not move the robot.

The triangulated watch case is at approximately (0.302, -0.082, 0.836) m. Is it now standing 0.086 m above the table? With the table estimated at z = 0.75 m, that height seems plausible for an upright loop with a diameter of about 0.07 m and the case near its upper side. I estimate the ring center lower, around z = 0.79 m. This makes me question the earlier case-height estimate of z = 0.784 m. That triangulation used head-camera pixel (462, 230) and wrist-camera pixel (512, 145), with a residual of about 5 pixels, so perhaps the features were mismatched. Could the initial case actually have been near z = 0.80 m? The loop now appears upright after the drop. A grasp contact at the case height of z = 0.836 m, using a contact distance of 0.14 m along local +X, would require link6 at z = 0.976 m rather than 0.925 m. The previous grasp at link6 z = 0.925 m contacted the lower band or case around z = 0.785 m rather than its top, but it did hold the watch. I can instead grasp across the band’s diameter at link6 z = 0.94 m as before. The case is near y = -0.082 m, and the ring center may be near y = -0.09 m. The watch is not flat; I estimate its upright height at about 0.08 m. For placement, its bottom needs to reach the basket floor. With a top-down grasp at link6 z = 0.94 m, might the ring extend from z = 0.76 to 0.84 m? More specifically, the case top is estimated at z = 0.836 m, while contact 0.14 m below link6 would be at z = 0.80 m, around the middle of the case. After lifting link6 to z = 1.06 m, I estimate the contact at z = 0.92 m, the ring top at z = 0.95 m, and its bottom at z = 0.86 m. Lowering until the bottom reaches the floor at z = 0.75 m would suggest link6 at z = 0.95 m. With the rim estimated at z = 0.84 m, I should tilt the watch into the basket and lower it once it is over the interior. Another option is to release with its bottom at z = 0.80 m for a 0.05 m drop: link6 at z = 1.0 m would give an estimated contact height of 0.86 m and bottom height of 0.80 m. For the gold bar, the previously considered link6 placement height of z = 0.999 m gives an estimated object center at z = 0.89 m and bottom at z = 0.88 m, allowing a 0.12 m drop to the floor. Once tilted over the interior, I could lower link6 to z = 0.95 m, putting the center at z = 0.84 m and bottom at z = 0.83 m, below the rim but inside the basket. Releasing at link6 z = 0.97 m would put the center at z = 0.86 m and bottom at z = 0.85 m, just above the rim, with an estimated drop of 0.09 m. For the watch recovery, I first considered moving the open right gripper from (0.303, -0.043, 1.059) m to (0.30, -0.082, 0.98) m, descending 0.079 m and changing y by -0.039 m while retaining the top-down orientation. This would put contact near z = 0.84 m, perhaps too high, with fingertips around z = 0.822 m that could surround the upper case and band. I want to grasp across the ring’s middle at link6 z = 0.94 m, so I will approach at z = 0.98 m and then descend to 0.94 m. The ring’s outer width along Y may be 0.05 m, compared with an estimated open finger gap of 0.08 m. The current right wrist view shows the ring center near (400, 160) pixels and the case near (440, 170). The case’s estimated y = -0.082 m relative to link6 y = -0.043 m gives a relative Y offset of -0.039 m, consistent with its positive optical-X offset near pixel 440. Moving link6 to the case’s Y coordinate should center the case near image x = 320 pixels. The ring center may still be around image x = 390 pixels, suggesting another move of about -0.01 m along world Y. I’ll therefore use the right approach target (0.302, -0.09, 0.98) m and inspect its alignment during descent. At the same time, I’ll move the left arm to (-0.345, 0.005, 0.99) m with the tilted orientation at interpolation fraction 0.4, keeping the gold bar held. The left rotation from its current top-down orientation is about 0.838 rad, within the command limit. I initially considered 6 control steps, and 3–6 steps might be suitable for the right approach, but I’ll use 4 to reduce the risk of overshooting near the watch. I estimate that 4 steps may move the right arm about 0.05 m to z = 1.009 m, still short of its target, while the left completes only part of its rotation.

The right watch’s ring is visible from above and looks circular on the table, so I am uncertain whether it is upright. The case is on the right. Its triangulated height of z = 0.836 m seems too high if the ring is lying flat. Perhaps the table surface is at z = 0.82 m rather than 0.75 m? But that would put the chocolate bar at z ≈ 0.78 m below the table, which is impossible. The gold bar’s triangulated height was z = 0.778 m, so I take the table to be below z = 0.77 m. The watch case at z = 0.836 m could therefore have a standing height of about 0.06 m. The ring may only appear flat because the camera is looking downward. Could its plane be horizontal at z = 0.78 m while the case reaches z = 0.836 m? Is the white case standing on edge with the band loop horizontal? Perhaps the watch has a coiled band lying horizontally and a case standing vertically about 0.05 m high. Its exact configuration remains uncertain, but grasping across the band still seems suitable. In the left wrist view, the basket bottom is visible beneath the gold bar. The gripper is tilting, and the bar appears over the white basket’s interior. I’ll continue toward the left placement target and the right regrasp approach pose for 6 control steps.

The gold bar appears near pixel (190, 152) in the high-camera view, perhaps near the white basket’s back wall. I estimate the basket interior spans image x = 150–240 and y = 150–195 pixels. The held bar’s height of about 0.9 m shifts its projection upward. If released at world y = 0.08 m, I expect its floor-level projection near image row 179, inside the basket. The left arm has reached its target position, but its rotation is still lagging. Its measured quaternion is [0.793, 0.002, 0.564, 0.228], rather than the target approximately [0.812, 0, 0.480, 0.332], in wxyz order. I estimate its orientation corresponds to an interpolation fraction of about 0.26. Its current local +X direction may be approximately (0.33, 0.41, -0.85), giving a grasp-contact Y offset of 0.057 m and an object Y coordinate of 0.061 m. I estimate the contact height as 0.992 - 0.119 = 0.873 m and the bar’s bottom height as about 0.86 m. Releasing now should let it land near world y = 0.06 m, inside the white basket. Although it currently appears at pixel (190, 152) at a height of about 0.87 m, I expect its floor-level projection at y = 0.06 m to be near image row 186, also inside. Could the bar catch on the back rim? The wrist view shows the white basket floor directly underneath it, so release looks safe. I’ll hold the left arm at its measured pose and open its gripper while the right continues approaching the watch. The right target is (0.302, -0.09, 0.98) m; its current Y coordinate is -0.07 m and its height is 1.009 m. I think it needs another 4 control steps, so I’ll use 4 steps for the release and continued approach.

The gold bar is stable inside the white basket. Together with the green pepper in the blue basket, that makes two objects sorted. The watch ring appears centered near pixel (332, 190) in the current right wrist view; I also estimate its horizontal center at about 330 pixels and the case at (390, 180). The right link6 is at (0.302, -0.085, 0.994) m, close to its approach target of (0.302, -0.09, 0.98) m. The open fingertips are visible at the bottom corners. Its orientation is slightly off nominal, perhaps because of contact, but looks acceptable. I should descend toward a watch grasp height of about 0.94 m, as before. I considered staging the descent through 0.96 m and then 0.94 m. Another option is three steps toward 0.95 m, which might only bring the measured height to about 0.965 m, followed by two steps toward 0.94 m. While the right arm regrasps the watch, the left can withdraw from the basket and prepare for the purple chocolate or a yellow pepper. One clearance option is to move to (-0.35, -0.10, 1.06) m and restore a top-down orientation. My estimated XY locations are (-0.389, -0.206) m for the purple chocolate, (-0.27, -0.163) m for the left yellow pepper, and (-0.14, -0.162) m for the middle yellow pepper. The left link6 is currently at (-0.343, 0.004, 0.992) m with a tilted orientation. I could move toward a purple-bar approach pose at (-0.389, -0.206, 1.02) m. For the purple bar, should I close along world X or world Y? Its vertical appearance near high-camera pixel (126, 289) suggests that its long axis is along world Y, although I briefly considered whether it could instead be along world X. Closing along X across its short dimension seems better. The nearby left yellow pepper is about 0.126 m away; with open fingers approximately ±0.04 m along X, I initially estimate about 0.08 m of clearance from it. The top-down quaternion that closes along world X is [0.5, 0.5, 0.5, -0.5] in wxyz order. Its precheck failed earlier over the green pepper, but that was from a particular configuration; it may be reachable over the purple bar, closer to the left side. I also wondered whether [-0.5, 0.5, 0.5, 0.5] would give the same rotation, but I have not resolved that question. Keeping the tilted orientation is another possibility, though I prefer a top-down grasp. The downward orientation [0.707, 0, 0.707, 0] would close along the bar’s long Y axis, which is less suitable for this narrow package. The current left quaternion is [0.793, 0.002, 0.564, 0.228]. My dot-product estimate with the X-closing goal is 0.3965 + 0.001 + 0.282 - 0.114 = 0.5655, giving an orientation distance of 1.934 rad, above the 1 rad command limit. I therefore need an intermediate rotation. I considered a safe intermediate position at (-0.38, -0.12, 1.05) m. Alternatively, returning first to the Y-closing top-down orientation gives an estimated dot product of 0.560 + 0.399 = 0.959 and a distance of 0.575 rad; I could then decide over the purple bar and rotate another 90 degrees later. However, closing across X remains preferable. The estimated purple-to-yellow XY displacement is (0.119, 0.043) m. The purple grasp’s positive-X finger would be near x = -0.349 m, while the yellow pepper extends to about x = -0.30 m, leaving an estimated 0.049 m gap. That looks safe enough for the X-closing grasp. I’ll plan a left intermediate target at (-0.389, -0.206, 1.04) m, about 0.211 m from its current position, with a 0.8 rad rotation toward the X-closing goal. The right will descend toward 0.95 m during a proposed four-step action. The left path from the white basket toward the purple bar is above the table with the gripper open. At link6 height 1.04 m, a possible downward fingertip extent of 0.12 m would put the tips near 0.92 m, above the pepper’s estimated height of 0.81 m. First, I’ll calculate the intermediate left quaternion from its current orientation to the chosen goal.

The gold bar remains supported in the white basket, so I’ll move the left gripper toward the purple chocolate using the calculated intermediate rotation toward a grasp across its short dimension. Meanwhile, I’ll lower the open right gripper partway toward the watch band for the regrasp.

The watch ring shifted down and left in the right wrist image, and the band contacted the left finger during the descent while the gripper was commanded open. The opening command is again 0.802; I suspect contact may be causing automatic closure, though that remains uncertain. The case appears near pixel (370, 350), and the ring center near (300, 300). The right pad is still far away at about (580, 280), while the left pad touches the band near (220, 260). Closing should move the right finger leftward toward the case and grasp across the ring. I’ll close now. The left arm is still moving slowly toward the purple chocolate. Its target quaternion is approximately [0.7549, 0.237, 0.605, -0.087], while its measured quaternion is [0.795, 0.078, 0.587, 0.128], both in wxyz order, and its Y position has barely progressed. Perhaps joint limits and the combined rotation and translation are slowing the motion along the prechecked path. I’ll continue toward the same target. I considered 6 steps for the left approach, but I’ll use 3 shared control steps while closing the right gripper.

The watch has moved left to approximately pixel (450, 228) in the high-camera view, suggesting that closure dragged it slightly. It may still be held, but I need to verify the grasp. I’ll make a 0.04 m vertical test lift with the right arm, targeting a link6 height of about 0.97 m, while the left continues approaching the purple chocolate. I considered 6 control steps for the left approach, but I’ll use 3 shared steps for this test lift.

The right watch appears near (455, 222) pixels in the high-camera view after the lift, though the visible movement is small. The band seems to remain in roughly the same position relative to the wrist camera. Is the case held near the bottom, with the loop behind the closed pads? The opening command is 0, but that alone could also mean the gripper holds nothing. In obs_000256, I estimated the case at (340, 350) pixels and the band extending to (160, 290) in the right wrist view. In obs_000259, the case may be hidden between the pads near the bottom; the loop is at the upper left, and the pads meet around (320, 280). If the watch had stayed on the table, I would expect it to look smaller after the lift. Instead, the loop has shifted left and upward while retaining a similar apparent size of about 220 pixels. Its high-camera position also moved from (450, 228) to (455, 222), an upward shift of 6 pixels consistent with the lift. I therefore think it is held securely enough to proceed. For placement, I’m considering the tilted orientation at interpolation fraction 0.4 and a target object-center Y coordinate of 0.08 m. The current right link6 position is (0.302, -0.091, 0.967) m. I have been assuming a grasp contact 0.14 m along local +X, but does that point correspond to the case? The held object’s center may not be exactly at that distance. I should triangulate the held case or ring center from the current head and wrist views, determine its offset and height relative to link6, and then calculate the link6 target needed for placement on the red basket floor. A distinctive feature might be the buckle’s white tip on the left, tentatively at (454, 222) pixels in the high-camera view and (125, 281) in the wrist view. The case might be a better feature, but it may be hidden by the gripper. I estimate the visible ring near (459, 220) in the high-camera view, with the white case possibly on its right at (465, 222). I’ll make enlarged crops of the obs_000259 high and right wrist images with PIL to identify matching features more clearly.

I’ll inspect the enlarged head-camera crop of the watch to identify a clear feature to match with the wrist view. This should help refine its position relative to the gripper and choose a release pose inside the red basket.

I estimate the white watch case at pixel (152, 133) in the enlarged head-camera crop, corresponding to (458, 223.25) in the original image. The left side of the ring is near original-image pixel (450, 215). I’ll inspect the enlarged wrist-camera crop next.

The watch case is hidden behind the finger pads at the bottom of the wrist view, but the white buckle on the left is visible. The white feature at (458, 223) pixels in the head-camera image is the buckle, rather than the case I previously identified. I estimate the buckle’s white tip center at (230, 430) pixels in the enlarged wrist crop. This maps to original-image coordinates x = 70 + 57.5 = 127.5 and y = 170 + 107.5 = 277.5 pixels. The corresponding buckle center may be at (458, 223) in the head view and approximately (128, 278) in the wrist view. I’ll triangulate using these estimated correspondences.

The head-camera vertical residual of about -14 pixels is large, so the feature correspondence is probably wrong. The white feature at (458, 223) pixels in the head view may be the case, while the wrist feature is the buckle. The case is hidden, so I cannot triangulate it from these views. I could try a distinctive point on the upper-left band, but a precise localization may not be necessary. The grasp geometry remains uncertain. At the grasp, right link6 was at (0.302, -0.09, 0.931) m, and the earlier case estimate was (0.302, -0.082, 0.836) m. Assuming the held case center is 0.14 m along local +X gives (0.302, -0.09, 0.791) m, whereas the case estimate at z = 0.836 m suggests a contact distance of 0.095 m, closer to 0.10 m than 0.14 m. Could the fully closed gripper instead be contacting the case near the fingertip extent of 0.1576 m? I am not sure. I could estimate the current watch position from the head view and a fixed offset from link6, using the before-and-after observations. After the test lift, the watch appeared at (455, 222) pixels; the earlier table-level ring appeared at (466, 216) pixels. Closure shifted it in X and Y. However, recovering its world position from the head view still requires an unknown height. Matching a band hole between the head and wrist views could resolve this, but the head-view features are too small. A single wrist view with an assumed watch orientation is another option. Instead, I can choose a placement farther inside the basket that tolerates the uncertain offset. I want the tilted gripper to extend the watch toward world y = +0.1 m. Even with about 0.03 m of offset uncertainty, a target y = 0.10 m would lie within the estimated basket bounds of [-0.02, 0.18] m. With link6 at y = 0 m and orientation interpolation fraction 0.4, a contact distance of 0.14 m gives contact y = 0.075 m. If the band extends approximately ±0.04 m, its Y extent would be [0.035, 0.115] m, inside the basket. At link6 z = 1.0 m, I estimate the case contact at z = 0.89 m and the loop bottom near z = 0.84 m, above the rim. If the contact distance is instead 0.10 m, the contact would be at y = 0.054 m and z = 0.922 m, with the bottom perhaps at z = 0.87 m; that also appears sufficiently far inside. Thus, a link6 target of (0.26, 0, 1.0) m with the tilted orientation should put the object around x = 0.292–0.305 m and y = 0.05–0.08 m. This resembles the successful gold-bar placement from left link6 at (-0.343, 0.004, 0.992) m with an actual interpolation fraction near 0.26. The watch’s proposed fraction of 0.4 extends it farther along +Y. I’ll target right link6 at (0.26, 0, 1.0) m with quaternion [0.812, 0, 0.4799, 0.3321] in wxyz order. From its current position of (0.302, -0.091, 0.967) m, I estimate a position distance of 0.108 m and an orientation change of 0.838 rad. This is likely reachable. Once it arrives, I’ll check that the wrist view shows the red basket floor beneath the watch before releasing it. The left arm will continue toward the purple chocolate. Its current quaternion is [0.787, 0.141, 0.599, 0.043], and its intermediate target is approximately [0.755, 0.237, 0.605, -0.087], both in wxyz order. It still needs to move from XY coordinates (-0.36, -0.08) m toward (-0.389, -0.206) m. I considered another 6 control steps, but I’ll use 5 shared steps for the right tilt and the continued left approach.

The watch dropped during the tilt. In the high-camera view, it is near pixel (475, 226), outside the basket, and the right wrist view shows the band back on the table with the pads apparently closed around nothing. The grasp was insecure and slipped during rotation. The previous test lift may have lifted it before it partially slipped, but it is now dropped, so I need to recover it again. I should grasp the white case directly across its sides, aligning the closing direction with the case’s short dimension and choosing the correct contact point near its top. This should be more robust than closing around the delicate band. First I need to localize the dropped watch and understand its shape. In obs_000264, I estimate the ring at pixel (500, 180) in the right wrist view, with the white case above the band near (480, 105). A possible matching case center in the high-camera view is (483, 223), or perhaps (480, 224), while the watch as a whole is near (475, 226). I’ll enlarge the head and wrist crops to refine these correspondences, then use the current right wrist calibration to triangulate the case.

I’ll inspect the enlarged head-camera crop to identify the watch’s rigid case more precisely. Matching it with the wrist view should help refine the grasp location after the watch slipped during rotation.

I estimate the white watch case at pixel (198, 116) in the enlarged head-camera crop. In the original image, this corresponds to x = 440 + 39.6 = 479.6 pixels and y = 200 + 23.2 = 223.2 pixels. The case appears rectangular and angled along the band on the right. I’ll inspect the enlarged wrist-camera crop next.

I estimate the white watch case’s center at (456, 225) pixels in the enlarged wrist-camera crop. This corresponds to original-image coordinates x = 400 + 91.2 = 491.2 pixels and y = 60 + 45 = 105 pixels. The case center in the head-camera image is approximately (480, 223) pixels. I’ll triangulate its position using these matching features.

The latest estimate puts the watch case at approximately (0.344, -0.071, 0.793) m, rather than the previous estimate of (0.302, -0.082, 0.836) m. The drop appears to have changed its position and orientation significantly. With the table estimated at z = 0.75 m, a case height of about 0.04 m seems plausible for the loop resting upright on its side. I need to pinch the rigid case across its narrow dimension. In the wrist image, I estimate its horizontal length at about 100 pixels and its vertical thickness at about 70 pixels, though its width remains uncertain. Another horizontal-length estimate is about 110 pixels, corresponding to roughly 0.03 m along world Y. What is its width along world X? The case’s long axis appears tangent to the band. The top-down orientation that closes along world Y produces horizontal closure in the wrist image. That might pinch along the case’s length, from the red strap on the left toward the white case on the right, which may not be ideal. Rotating the gripper 90 degrees to close along world X would instead pinch across the narrower, vertically appearing dimension. I considered using quaternion [0.5, 0.5, 0.5, -0.5] in wxyz order for the right arm, but the orientation difference from its current configuration might be about 2.4 rad and would require an intermediate rotation. Either closing direction might fit if the case is about 0.03 m along world Y and 0.04 m along world X. I still need to understand its shape in world coordinates. The current right quaternion is [0.758, -0.021, 0.645, 0.097], so the gripper is not exactly top-down. Optical X is approximately opposite world Y with some tilt, while optical Y combines world X and Z components. The case’s horizontal appearance therefore suggests that closing along world Y would contact its long axis, possibly including the strap. Nevertheless, centering precisely on the rigid case may provide enough contact area without requiring the larger rotation. I could rotate after approaching, but I’ll first retain the simpler Y-closing orientation and aim to pinch the case’s sides, which appear near wrist-image x coordinates of 450 and 540 pixels, rather than the whole ring. The previous grasp at end-effector XY coordinates (0.302, -0.09) m was 0.042 m left of the newly estimated case at (0.344, -0.071) m along world X. That explains why it grasped the band rather than the case. Centering on the case is the crucial correction. Using its estimated center height of 0.793 m and a contact distance of 0.14 m gives a proposed link6 grasp height of 0.933 m. This is nearly the previous height, but shifts the target by +0.042 m along X and +0.019 m along Y. The estimated open gap is 0.08 m and the case dimensions are around 0.03 m. The pads may touch the surrounding band during descent, but I intend to close on the rigid case. I’ll approach top-down at z = 1.0 m, then descend toward 0.935 m and inspect whether the case is centered at the grasp point. Returning from the current right quaternion to the nominal Y-closing quaternion [0.707, 0, 0.707, 0] requires about 0.26 rad, which seems straightforward. From the current right position of (0.279, -0.056, 0.978) m, I estimate the distance to the approach target (0.344, -0.071, 1.0) m as 0.068 m. The left arm is at (-0.366, -0.112, 1.02) m with its orientation near the intermediate target, and still needs to approach the purple chocolate. I’ll continue toward its existing target while moving the open right gripper above the case, using 5 control steps.

The watch case is slightly right of the closing center, so I’ll correct that offset and lower the open right gripper toward the rigid case for a more secure regrasp. Meanwhile, I’ll use the calculated intermediate rotation to bring the left gripper closer to its purple-chocolate grasp orientation.

In the right wrist view, I estimate the watch case center at (340, 213) pixels and the ring center at (385, 260) pixels. The right link6 height is now 0.948 m. The inner finger pads are near (200, 280) and (480, 280) pixels, and the case’s horizontal width is about 80 pixels. Will closure initially contact the outer band near image x = 280 and 480 pixels? The right pad appears to touch the band at x = 480 already, while the left pad at x = 200 has not yet contacted it. Closing could squeeze the ring, with the right pad contacting the band or case and the left pad contacting the band. This might still grasp the whole watch. The case’s horizontal center at x = 340 is reasonably close to the closing center at x = 320. To pinch the case specifically, I need to adjust the end effector’s x position so the case reaches the contact row near image y = 330 pixels. Its center is currently at y = 213; I expect lowering link6 to z = 0.925 m to bring it near y = 300. The gripper closes horizontally through the pad contact regions around y = 330. The case currently extends from approximately y = 180 to 250 pixels, and I expect that span to become y = 250–340 after descending to 0.925 m, placing it within the contact regions. The reported right opening command is 0.775. I suspect its automatic decrease is due to contact with the band on the right, though that remains uncertain. I’ll lower the right arm toward z = 0.925 m for 2 control steps with the gripper commanded open, then close afterward. The left orientation is still lagging but progressing, so I’ll continue toward its same alignment target during these 2 steps.

In the right wrist view, I estimate the watch case center at (350, 250) pixels, with the inner left pad at (260, 290) and the inner right pad at (450, 290). The case appears about 100 pixels wide. Will the fingers close directly on its sides? The left finger is at x = 260 pixels and the case’s left edge near x = 310; the right finger is at x = 450 and the case’s right edge near x = 390, so the fingers are still open around the case. The ring’s outer right edge is near x = 510 pixels, behind the finger, though the finger may still contact the band. I’ll close the right gripper for 3 control steps while the left continues its approach for the same 3 steps.

The watch case is now vertical between the right finger pads at approximately (320, 270) pixels. The opening command is 0.008, nearly closed, which I attribute to the case being thin. This looks like a direct pinch on the case and should hold more securely during a test lift. I’ll raise the right link6 by 0.04 m to z = 0.969 m over 3 control steps to verify the grasp. I considered advancing the left arm to its final orientation, but its current quaternion is [0.702, 0.327, 0.593, -0.22] in wxyz order, still about 0.4 rad from the intermediate target [0.612, 0.423, 0.557, -0.369]. I’ll continue toward that intermediate orientation during the right test lift.

Did the watch lift in the high-camera view? It still appears near pixel (490, 232), similar to its earlier position at (480, 235). However, the case remains between the pads in the wrist view, and the band looks unchanged relative to the gripper, so I believe it is held. I would prefer to avoid rotation if a translation-only, top-down placement can reach far enough into the red basket. I considered moving toward y = +0.08 m. The earlier top-down target at y = 0.04 m, z = 1.03 m failed, but at x = 0.344 m and a lower height of z = 0.99 m, y = +0.04 m might be reachable. The right link6 is currently at (0.344, -0.08, 0.965) m. Increasing Y by 0.08 m to y = 0 m at the same height might also be reachable because it is farther right and lower. Another possible top-down target is (0.344, 0.04, 0.99) m, which I estimate is 0.122 m away. If that reaches y = 0.04 m, the case might be near that same Y coordinate, but I do not know which world direction the band extends. In the wrist view, the loop extends upward and rightward from the case; in the high view, it may extend leftward. A link6 target at y = 0.07 m, z = 0.99 m would give more confidence in containment, but might be unreachable. I also considered translating at a lower height of z = 0.95 m as Y increases. A target of (0.34, 0.03, 0.97) m is approximately 0.114 m from the current pose and seems likely to pass. The previous target at x = 0.30 m, y = 0.04 m, z = 1.03 m failed by about 20 mm; lowering it by 0.06 m might make it reachable. At that lower pose, I estimate the case contact at z = 0.83 m and the band bottom at z = 0.76 m, potentially inside the rim. The problem is clearance during transport. At the current pose, my case-height estimate is 0.965 - 0.136 = 0.829 m. Could the band bottom still be around z = 0.75 m, with the loop resting? The measured lift was 0.036 m, so another estimate puts its bottom just above the table at z = 0.786 m. Translating horizontally at that height would put the band bottom below the estimated rim height of 0.84 m and risk hitting the front wall. I should lift to z = 1.04 m before translating, then lower inside, but the higher reach already failed at z = 1.03 m. I could lift at the current Y coordinate to z = 1.03 m, move toward y = -0.02 m near the front wall, and then lower or tilt. The direct case grasp may now make rotation a better option. The case is thin, the opening command is 0.017, and it appears securely pinched. The previous band grasp slipped during rotation, but I expect this case grasp to hold better. I’ll use the tilted placement at interpolation fraction 0.4, targeting right link6 at (0.30, 0, 1.0) m with quaternion approximately [0.812, 0, 0.4799, 0.3321] in wxyz order. The estimated contact offset is +0.045 m along X and +0.075 m along Y, putting the case center at approximately (0.345, 0.075, 0.891) m, within the red basket’s estimated X bounds of [0.18, 0.42] m. I’ll use link6 x = 0.30 m rather than 0.26 m so that the tilted case remains near its current x = 0.344 m, with the proposed case x = 0.345 m. The ring may extend around that point above the basket. I estimate the rotation from the current top-down pose as 0.838 rad and the position change as 0.109 m. I’ll execute only 3 control steps rather than 5, then inspect for slipping. The left arm will continue toward its existing alignment target during those same 3 steps. The direct case pinch should hold, but I will check before proceeding or releasing.

The watch case is still held between the right finger pads during the tilt. I’ll continue toward the same targets for another 3 control steps.

The right arm’s measured Y coordinate is still -0.048 m rather than the target of 0 m. Its progress is slow, likely because of the orientation change and kinematics. In the right wrist view, the red basket is on the left and the watch loop still appears over the table to the right. I think another 3–6 control steps are needed, and I’m considering 6 steps toward the same right target. The left arm has reached its intermediate quaternion, approximately [0.613, 0.422, 0.558, -0.367] in wxyz order. The purple chocolate appears centered near pixel (400, 140) in the left wrist view, offset from the closing center at image x = 320 pixels. Completing the top-down orientation that closes along world X should shift its projection. I estimate the remaining orientation distance as 0.534 rad, within the 1 rad limit, so I can target the final quaternion [0.5, 0.5, 0.5, -0.5] while keeping the left position unchanged. I’ll use 5 shared control steps to complete the left alignment and continue the right arm toward its existing placement target.

The left arm’s final-orientation precheck failed again, as it did earlier. A wrist joint limit may be responsible; perhaps the downward orientation that closes along world X is unavailable at this position with the chosen quaternion. Negating the quaternion to [-0.5, -0.5, -0.5, 0.5] in wxyz order gives exactly the same rotation, so that would not help. Another option is to keep local X downward but align local Y with world -X. This preserves the closing axis while swapping the fingers and reversing the camera view. With local X = (0, 0, -1), local Y = (-1, 0, 0), and local Z = X cross Y = (0, 1, 0), the rotation matrix would be [[0, -1, 0], [0, 0, 1], [-1, 0, 0]]. Its quaternion might be [0.5, -0.5, -0.5, -0.5] in wxyz order; I would need to calculate it. This is a 180-degree rotation about the vertical axis from the original X-closing orientation and might be reachable with a different joint 6 configuration. From the current quaternion [0.613, 0.422, 0.558, -0.367], my estimated dot product with that alternative is 0.306 - 0.211 - 0.279 + 0.1835 ≈ 0, giving an orientation distance near π rad. I could rotate gradually, but that may be unnecessary. I could instead use the known reachable downward orientation that closes along world Y and pinch the purple chocolate’s ends. However, its estimated length of 0.10 m exceeds the estimated open gap of 0.08 m. The gap might be 0.09 m, and a diagonal grasp might still fit within an estimated maximum opening of 0.09 m, but this is uncertain. The current orientation may already be adequate. The purple bar appears vertical in the wrist image, near pixel (390, 140), while local Y projects horizontally, so the fingers seem to close across its short dimension. Local Y is not exactly world X, but may be close enough. I tentatively estimate local X as (0.2, 0.7, -0.7), meaning the fingers point diagonally forward, rightward, and downward rather than straight down. I should calculate the actual local axes before deciding. Local Y may have world X and Y components near 0.96 and 0, respectively, but its remaining component is still uncertain. I can retain this reachable orientation and align by translating link6. Its current position is (-0.389, -0.206, 1.04) m. The purple bar’s center may be near (-0.389, -0.206, 0.758) m; the earlier table-height-based estimate was (-0.3894, -0.206, 0.758) m, and I have not observed subsequent movement. Because local X has horizontal components, a contact point at link6 plus d times local X would not currently share the object’s XY coordinates. The wrist image places the bar about 70 pixels right of the closing center and above the intended contact location. Using the fixed camera model, I can choose a link6 position that puts the object at local coordinates (d, 0, 0). For d = 0.14 m, the intended grasp projection is approximately pixel (320, 330). The position relation is link6 = object - d times local X. As an illustrative estimate, with object-center z = 0.77 m and local X’s vertical component equal to -0.85, link6 z would be 0.889 m; the horizontal coordinates would also need adjustment. Such a target might be reachable without another rotation. I’ll calculate the local X, Y, and Z directions from the measured obs_000288 quaternion. For the immediate calculation, I’ll use the purple-bar center estimate (-0.389, -0.206, 0.765) m and obtain link6 targets for a grasp distance of 0.14 m and a pregrasp distance of 0.22 m. Then I can approach and descend while holding the current orientation, provided the calculated local Y direction confirms suitable closure across the bar’s short dimension.

The calculated local X direction is nearly downward, (0.108, 0.021, -0.994), and local Y is mostly aligned with world X, with some tilt. The current orientation is therefore suitable for a nearly top-down grasp across the purple bar’s short dimension; I do not need the exact nominal quaternion. The calculated left link6 contact target is approximately (-0.404, -0.209, 0.904) m, and the pregrasp target is (-0.413, -0.211, 0.984) m. The measured position is (-0.389, -0.206, 1.04) m, so the pregrasp move lowers it by 0.056 m and shifts it by -0.024 m along X. I’ll retain the current quaternion [0.613, 0.422, 0.558, -0.367] in wxyz order. I expect this left target to pass the precheck. The purple bar’s center height is still estimated at z = 0.765 m. I initially considered the contact target at link6 z = 0.904 m, but with the fingertips extending 0.1576 m along local X, their estimated height would be about 0.7475 m. Using the rounded vertical component gives 0.904 - 0.1566 = 0.7474 m, about 3 mm below the estimated table height of 0.75 m, which could cause a collision. I’ll instead use a final grasp height of z = 0.91 m, putting the fingertips near z = 0.7534 m and the contact point 0.14 m along local X near z = 0.771 m. The pregrasp height is approximately 0.98 m; the immediate target remains 0.984 m. The rejected command moved neither arm, so the right still needs to continue its watch placement. I’ll use 5 control steps for the left pregrasp move and the unchanged right placement target.

The left pregrasp target failed with a position error of about 48 mm while retaining the current orientation. Could a wrist joint limit be preventing the lower pose? The precheck stalled after only 1 iteration, which might mean the current joint configuration is near a boundary and cannot begin descending with this quaternion, perhaps because of joint 6. This remains uncertain. I need to find a feasible grasp orientation through the precheck. One option is to adjust toward the known reachable top-down orientation [0.707, 0, 0.707, 0] in wxyz order, which closes along world Y, and try a link6 position of (-0.389, -0.206, 0.93) m over the purple bar. That would close along the package’s long axis. Its estimated length is 0.10 m and the estimated open gap is 0.08 m, although a diagonal grasp might still fit. Another option is to return to that Y-closing orientation and then rotate around the vertical axis to an alternative top-down orientation with local Y along world -X. The nominal orientation with local Y along world X failed, possibly because of a wrist-roll singularity at the current joints. Taking a -90-degree yaw route rather than a +90-degree route might avoid a joint limit while preserving the desired closing axis. I could first return to [0.707, 0, 0.707, 0] at the current high position, where it was reachable previously, then rotate toward the alternative orientation. From the current quaternion [0.613, 0.422, 0.558, -0.367], the dot-product contributions are approximately 0.433 from the scalar components and 0.394 from the Y components, with zero contributions from X and Z. Their sum is 0.827, giving an estimated orientation distance of 1.204 rad, above the 1 rad command limit, so this return would require an intermediate rotation. The alternative quaternion might be [0.5, -0.5, -0.5, -0.5], but I should check it. I’ll use SciPy to derive the quaternion for local X pointing downward and local Y pointing along world -X, then calculate the orientation distances from the Y-closing top-down orientation to both X-closing alternatives.

The right gripper still appears to hold the watch case, but its measured Y coordinate is only -0.038 m compared with the target of 0 m. Progress is slow, perhaps because the arm is near joint limits. In the wrist view, the red basket covers the left half of the image, while the band is on the right and partly outside. I considered changing the right target from (0.30, 0, 1.0) m to (0.27, 0.02, 1.0) m. Would moving link6 left also move the contact point left? With the tilted grasp’s positive X offset, I estimate the case would be at x = 0.315 m, and targeting y = 0.02 m would put the contact at y = 0.095 m, farther inside. However, that target might fail the reach precheck. The current right quaternion, [0.785, -0.137, 0.592, 0.118] in wxyz order, still differs from the desired [0.812, 0, 0.480, 0.332]. The orientation is lagging, including its X component. Could contact with the red basket wall be obstructing the motion? The band loop appears to press against the front wall in the wrist view. In the high-camera view, the right gripper is at the basket’s front-right corner, with the watch near pixel (493, 204) on the front wall. The small amount of motion could be due to a collision as I try to advance with the band below the rim. I should lift farther before continuing the tilt. At the current link6 height of 0.988 m, I estimate the case contact height near 0.85 m and the band bottom near 0.78 m, below the estimated rim height of 0.84 m. Another estimate, using the partial tilt’s local X vertical component of about -0.86 and a contact distance of 0.14 m, puts the contact at z = 0.868 m and the band bottom near 0.79 m. A link6 height of 1.07 m should put the bottom near 0.87 m. The earlier lift to 1.059 m used a band grasp and was followed by release outside the basket; the direct case grasp now gives me another opportunity to lift clear. I considered lifting vertically with either the current orientation or a top-down orientation. The existing target height of 1.0 m may be too low and could be causing dragging. A lift to 1.08 m at x = 0.30 m, y = -0.038 m while holding the current quaternion would allow me to resume the inward motion and tilt after clearing the rim. Is that vertical lift reachable with this unusual current quaternion? A previous top-down precheck failed at y = 0.04 m, but the current y = -0.038 m may be reachable. I estimate a position change of 0.092 m for the 1.08 m option, with orientation held steady. To avoid another combined precheck failure involving the left arm, I could hold it stationary rather than attempt an intermediate reorientation at the same time. I’ll leave the left arm in place and use a short 3-step right-arm lift toward z = 1.07 m, retaining the current right quaternion and keeping the case grasp closed.

The right link6 has lifted to z = 1.031 m, but the watch band still appears outside the red basket, to the right in the wrist view. I need to move it farther along +Y, and perhaps toward -X. The current quaternion has an X component of -0.137 because the orientation is lagging, and the camera is rotated. The desired tilted quaternion [0.812, 0, 0.480, 0.332] in wxyz order should bring the band forward along world +Y into the basket, perhaps moving it leftward in the image. I’ll change the right target to (0.30, 0, 1.06) m rather than using z = 1.0 m, to retain clearance while completing the tilt. My estimated quaternion dot product is 0.637 + 0.284 + 0.039 = 0.96, giving an orientation distance of about 0.575 rad. I estimate the position distance as 0.064 m. This target is likely reachable, and I’m considering 5 control steps. The left arm can begin rotating back toward the reachable top-down orientation that closes along world Y while the right moves. It remains high above the purple chocolate, which seems safe. Its current quaternion is [0.613, 0.422, 0.558, -0.367] in wxyz order. I estimate a dot product of 0.827 with the Y-closing goal and an orientation distance of 1.204 rad, so I need an intermediate rotation. I’ll calculate a quaternion for a 0.75 rad increment, using an interpolation fraction of approximately 0.62. My tentative intermediate quaternion is [0.657, 0.329, 0.633, -0.263], but I’ll compute it with the tool before using it.

I’ll hold the left arm’s position and target quaternion [0.70075, 0.1644, 0.6793, -0.1430] in wxyz order. This rotates it toward the top-down orientation that closes along world Y. The right arm will continue toward its placement target with the tilted quaternion. I’ll use 5 control steps.

The right wrist view now shows the watch band directly over the red basket floor, with the case near image x = 320 pixels. The right link6 is at (0.3, -0.006, 1.056) m, and its measured orientation is still only partly tilted toward the target. Releasing here should let the watch drop inside. I should check that the whole band is within the basket’s footprint. The loop spans approximately image x = 330–520 and y = 120–310 pixels. The visible red floor extends across x = 0–450 pixels, with the right rim near x = 550 pixels. The rightmost part of the band is close to that rim, but I judge it to be inside. In the high-camera view, the watch is near (500, 153) pixels, perhaps over the basket’s back-right area. I expect the drop to shift its projection down to about image row 190 at floor height, still inside. I’ll open the right gripper while holding its measured pose and continue the left arm’s reorientation toward the top-down grasp that closes along world Y. The left’s current quaternion is [0.648, 0.351, 0.603, -0.305], and its intermediate target is approximately [0.700, 0.164, 0.679, -0.143], in wxyz order. I estimate the remaining orientation distance as about 0.5 rad. I’ll use 3 shared control steps for the right release and continued left rotation.

The right-side watch is now contained in the red basket. In the high-camera view, it appears near pixel (490, 155), perhaps toward the back-right, and the wrist view confirms that it is resting upright on the floor near the back edge. Three objects are sorted: the green pepper, gold chocolate, and right-side watch. The middle watch remains outside near pixel (327, 246), along with the purple and red chocolates and two yellow peppers. I can assign the middle watch and red chocolate to the right arm, and the purple chocolate and peppers to the left. There are five objects remaining and 795 control steps available. Progress has been slow with small actions, so I should use larger actions when the path is clear. For the purple bar, the left arm’s current quaternion is [0.666, 0.307, 0.626, -0.267] in wxyz order. The intermediate target is approximately [0.700, 0.164, 0.679, -0.143], after which I could use the downward orientation that closes along world Y or an alternative that closes along world X. The current local X direction may already be nearly downward, perhaps (0.13, 0, -0.99). The earlier descent with the quaternion beginning with 0.613 may have failed because of joint limits, but the target x = -0.413 m may also have been too far left rather than the height being the problem. That pregrasp target, (-0.413, -0.211, 0.984) m, failed with about 48 mm of position error. Closing along world Y is an alternative, though it would close along the bar’s long axis. I could retain the current orientation and descend straight at x = -0.39 m, y = -0.206 m instead of shifting left to x = -0.413 m. The purple bar’s estimated x coordinate is -0.389 m. With a local X component of about +0.13 and a contact distance of 0.14 m, I estimate the contact center at x = -0.372 m, giving a grasp offset of 0.017 m, which seems acceptable. A link6 target height of 0.94 m instead of 0.904 m would put the contact at about z = 0.79 m, near the bar’s top. The fingertips might be at z = 0.78 m, above the estimated bar top of 0.77 m, so closure might only grip its upper edges. At link6 z = 0.92 m, I estimate the fingertips at z = 0.763 m, leaving clearance above the table at z = 0.75 m. A straight descent may pass the precheck because it avoids the leftward shift. I can test it after moving the right arm away. First, I’ll calculate the local axes for the current left quaternion.

The straight descent passed the precheck, and after 4 control steps the left link6 is at z = 0.996 m. The purple bar appears centered near pixel (358, 150). Local X points nearly downward and local Y is diagonal. In the wrist view, the bar’s long axis runs diagonally from approximately (390, 75) to (320, 230) pixels. Will horizontal closure cross its width appropriately? I am uncertain about the pads’ image-row alignment; after descending, the contact row at y = 330 pixels might intersect near the bar’s bottom edge. I should align its center with the grasp point. At link6 z = 0.94 m, I expect the bar’s image center to move down to approximately y = 300 pixels, while its x coordinate may remain near 358 pixels if I keep the same world XY position. At z = 0.92 m, I estimate its center at (358, 340) pixels, still slightly right of the closing center. A lateral correction could bring it to image x = 320 pixels. Optical X is opposite local Y, and the current local Y direction is approximately (0.739, 0.669, 0.075). An image x coordinate greater than 320 indicates a negative relative local Y coordinate. Moving the end effector horizontally along negative local Y should increase the object’s relative local Y coordinate and move its image leftward. My proposed correction is -0.008 × (0.739, 0.669) m, approximately (-0.006, -0.005) m, giving a possible link6 target of (-0.395, -0.211, 0.93) m. The current quaternion beginning with 0.666 may permit this lower straight approach with small lateral shifts. At link6 z = 0.93 m, I estimate the fingertips at 0.93 - 0.157 = 0.773 m, just above the bar’s estimated top at z = 0.77 m. A final link6 height of 0.915 m would put the fingertips near z = 0.758 m and a contact point 0.14 m along local X near z = 0.775 m. I therefore favor z = 0.915 m for the eventual grasp, with a pregrasp stop first. I initially considered z = 0.95 m for 3 steps, expecting about 0.04 m of actual descent from 0.996 m to approximately 0.956 m. The right arm should continue toward the middle watch approach at (0.023, -0.11, 1.02) m. From its measured position of (0.283, -0.029, 1.054) m, I estimate that target distance as 0.274 m, exceeding the 0.25 m limit. It still needs to reach the intermediate target (0.20, -0.15, 1.04) m. I considered 6 shared steps, with the left holding after reaching its 0.95 m target, but I’ll use 5 steps instead and target left z = 0.94 m without the lateral correction yet. It may reach approximately 0.946 m; even if it reaches 0.94 m exactly, I judge that to be a safe pregrasp height. The right target remains unchanged, and both grippers stay open.

The purple bar’s center appears near pixel (365, 210) at the pregrasp pose. At the final link6 height of 0.915 m, I expect its center to be near image y ≈ 330 pixels. The open pads are near image x = 60 and 520 pixels, and the bar is about 200 pixels wide, so it should fit between them. I wonder whether horizontal closure at the contact row of y = 330 pixels would grip its lower half. However, the bar’s long axis is tilted from vertical in the image, and I expect its center to reach that row after the descent, which looks suitable. I’ll move the left link6 to (-0.395, -0.211, 0.915) m while retaining its current orientation. The right arm will continue toward (0.20, -0.15, 1.04) m. I considered another 5 steps for that continued motion, but I’ll use 3 shared control steps for this final alignment and descent.

The purple bar’s center appears near pixel (340, 240). It may be close enough to the intended contact row at image y = 330 pixels. The finger pads are at the bottom left and right of the wrist view, and the bar spans image x = 220–450 pixels, with an estimated open gap of about 450 pixels. Is the closing direction diagonal? I expect the pads to contact the bar’s sides, so I’ll close the left gripper now. The right arm is still rotating and moving toward its approach pose, so I’ll continue that motion during the same 3 control steps.

The left pads appear to contact the purple bar’s sides, and the reported opening command is 0.334. I’ll test-lift it to a link6 height of 0.965 m. Meanwhile, I’ll move the right arm directly above the remaining middle watch at (0.023, -0.11, 1.02) m from its measured position of (0.231, -0.103, 1.047) m. I estimate that target distance as 0.210 m. The right gripper will point downward and close along world Y; the cross-table target may be reachable at the closer Y coordinate of -0.11 m, though the precheck still needs to confirm this. I’ll use 4 control steps for the left test lift and right approach.

During the test lift, the purple bar shifted from approximately (126, 291) to (116, 293) pixels in the high-camera view and remained stable relative to the wrist camera. I judge it to be held. The middle watch now appears near (335, 375) pixels in the right wrist view, with its case around (340, 355). At the proposed link6 target of (0.023, -0.11, 1.02) m, the case should become centered. I’ll refine its position using stereo triangulation from the current head and wrist views. In the initial high-camera image, I estimated the white case at (327, 244) pixels and the ring center at (327, 246). Their current high-camera positions appear unchanged. The case might be at (327, 244), or perhaps (329, 243), in the head view. In the wrist view, I estimate it near (343, 356), with the visible white rectangle’s center around (342, 357). I’ll triangulate using these approximate feature correspondences.

Moving the assumed head-camera case position upward increases the triangulation residual, so the correction may need to go in the opposite direction. The middle watch’s case may be lower in the head image, perhaps at pixel row 249, where the fit might be best. I’ll prepare enlarged head and right wrist crops to inspect the matching features.

The tentative case correspondences still give inconsistent triangulation results. I’ll inspect the enlarged head-camera crop of the middle watch to identify its rigid case more clearly for matching with the wrist view before grasping.

The watch case may be at the upper-left of the ring in the head-camera view, rather than the white feature on the right. I estimate the white rectangular case at enlarged-crop coordinates (130, 110) pixels, corresponding to original-image x = 300 + 21.7 = 321.7 pixels and y = 225 + 18.3 = 243.3 pixels. There is another white strap feature on the right. In the wrist view, the case may be the upper square near (342, 357) pixels. I’ll inspect the enlarged wrist crop to check that correspondence.

I estimate the middle watch’s case center at (375, 210) pixels in the enlarged wrist-camera crop. This corresponds to original-image coordinates x = 280 + 62.5 = 342.5 pixels and y = 320 + 35 = 355 pixels. In the head-camera image, I identify the case at the upper-left of the ring, near (322, 243) pixels. I’ll triangulate its position using the head-camera point (322, 243) and the wrist-camera point (342.5, 355).

The latest triangulation has smaller residuals and puts the middle watch’s case center at approximately (0.036, -0.121, 0.777) m. I’ll approach with the right link6 at (0.036, -0.121, 1.02) m, then grasp at about z = 0.92 m; adding the assumed 0.14 m contact distance to the case height gives 0.777 + 0.14 = 0.917 m. From the measured right position of (0.169, -0.107, 1.039) m, I estimate the approach distance as 0.134 m and expect it to be reachable. I can approach the watch while preparing the left arm to transport the held purple chocolate to the white basket. The left link6 is at (-0.394, -0.213, 0.963) m with quaternion [0.661, 0.309, 0.631, -0.263] in wxyz order. Local X points nearly downward, and local Y is diagonal. For placement, I want the purple bar’s XY center near (-0.30, 0.08) m. I could use the same tilted orientation as for the gold bar, at interpolation fraction 0.4, with quaternion approximately [0.812, 0, 0.4799, 0.3321]. My estimated quaternion dot product is 0.536 + 0.301 - 0.089 = 0.748, with no contribution from the X components. That gives an orientation distance of about 1.46 rad, exceeding the 1 rad command limit, so I need an intermediate rotation of 0.8 rad. Keeping the current nearly downward orientation is another possibility. I tentatively estimate local X’s world-X component as 0.066, though I would need to calculate it. A link6 placement target of (-0.30, 0.02, 1.02) m might be reachable. Earlier, the left arm reached (-0.262, -0.055) m in XY after 4 steps toward that target, and I changed to a tilted orientation before it arrived. A top-down pose at x = -0.3 m, y = 0.02 m therefore still seems likely to be reachable, but I want the object at y = 0.08 m for placement on the basket floor, so I prefer the tilt. I considered an intermediate quaternion about 0.55 of the way from the current orientation to the tilted goal, corresponding to roughly 0.8 rad of rotation. The transport could then pass through (-0.34, -0.06, 1.02) m, an estimated distance of 0.17 m, before reaching the final tilted link6 target of (-0.345, 0.005, 0.99) m. However, the purple bar needs more clearance before moving toward the white rim. Using the assumed contact distance, 0.963 - 0.14 = 0.823 m is an estimated contact height; the bar’s bottom might be around 0.81 m, below the rim. Since it has just been lifted about 0.04 m from the table, another bottom-height estimate is around 0.79 m. I’ll first lift the left link6 vertically by 0.087 m to (-0.394, -0.213, 1.05) m while rotating to the intermediate orientation. That seems safe, and the right can approach the watch at the same time. Afterward, the left can transport the bar at a clear height. I’ll now calculate the intermediate left quaternion toward the tilted placement orientation.

I’ll lift the left link6 vertically to z = 1.05 m while rotating it to quaternion [0.7949, 0.1472, 0.5843, 0.0710] in wxyz order, keeping the purple bar held. The right arm will approach the middle watch’s case at (0.036, -0.121, 1.02) m. These motions are independent, so I’ll execute them together for 6 control steps.

The middle watch’s case appears at pixel (320, 160) in the right wrist view, with the ring center at (310, 200). I’ll descend first to a link6 height of 0.94 m, then toward 0.92 m. Should I adjust Y? The case is exactly at image x = 320 pixels, so the horizontal alignment looks good. I’ll use 4 control steps for the descent to 0.94 m. The left arm can move toward the white basket while completing the tilted placement orientation, quaternion [0.812, 0, 0.4799, 0.3321] in wxyz order. From its current quaternion [0.767, 0.2, 0.608, -0.032], I estimate the dot product as 0.623 + 0.292 - 0.0106 = 0.9044, giving an orientation distance of 0.881 rad, below the 1 rad limit. The proposed link6 position is (-0.345, 0.005, 1.02) m. I estimate the position distance as 0.224 m, within the command limit. The purple bar remains held with the left link6 at a height of 1.049 m. Local X may already be partly tilted, and I estimate the bar’s bottom at 0.88 m, which looks safe. At the target link6 height of 1.02 m with the tilted orientation, I estimate the contact height at 0.91 m and the bar’s bottom at 0.90 m, leaving clearance. I considered 6 steps for the left transport and 4 for the right descent. I’ll use 4 shared control steps, allowing the left arm to move partway toward its target while the open right gripper descends.

The left arm is moving slowly because it is still rotating and has a long distance to travel. The middle watch’s case appears centered at pixel (320, 200) in the right wrist view. After 4 control steps toward the previous link6 height target of 0.94 m, the measured right height is still 0.976 m. I’ll lower its target to 0.925 m to reach contact height. I considered 4 more steps for the right descent and perhaps 6 for the left to continue toward its existing placement target. I’ll use 5 shared control steps for both arms.

The middle watch’s case appears centered at pixel (320, 310) in the right wrist view, close to the intended grasp row of y = 330 pixels. I’ll close the right gripper in place. The left arm is still at x = -0.385 m, y = -0.16 m. Perhaps the slow orientation change is limiting its progress. I estimate that it moves about 0.025 m per 5 control steps, so the remaining distance of about 0.18 m could require 35 steps. Its transport path looks clear, so I could continue toward the same target for 10 steps. The right closure may need only 3 steps, after which it can hold in place while the left continues moving. I would then test-lift the watch in the next action. This seems safe, though I’ll use 8 shared control steps for now.

The right pads appear to have closed directly on the middle watch case, which looks promising. I’ll test the grasp with a 0.04 m lift to a link6 height of 0.966 m while the left arm continues toward its existing placement target. The purple bar is now over the white basket’s front-left area, but it still needs to move farther along positive Y. I considered 5 control steps for the combined motion; I’ll use 4.

The middle watch’s case still appears pinched in the right wrist view. In the high-camera view, the watch may be near pixel (320, 244), or perhaps (321, 241), so its upward movement is not very clear there. The wrist view nevertheless suggests that it remains held. The purple bar appears directly over the white basket floor in the left wrist view, so I initially considered releasing it at the current link6 position of (-0.37, -0.088, 1.032) m, with the tilt near interpolation fraction 0.4. However, using an estimated local +X direction of (0.31, 0.51, -0.8) and a contact distance of 0.14 m gives a contact offset of approximately (0.043, 0.071, -0.112) m and an object-center estimate of (-0.327, -0.017, 0.920) m. That Y coordinate is -0.017 m rather than the intended 0.08 m. The floor appearing underneath the bar may be a perspective effect rather than proof that the bar is sufficiently far inside. I would like to calculate the local +X direction from the current left quaternion [0.817, 0.048, 0.517, 0.25] in wxyz order. If its world-Y component is about 0.53, the contact Y coordinate would be approximately -0.014 m. With the white basket’s interior Y range tentatively estimated as [-0.02, 0.18] m, that would put the bar only just inside the front. Could releasing it there leave it on the front edge or outside? I should check the floor-level projection of an object at x = -0.327 m, y = -0.014 m, z = 0.76 m. It might project near image row 211, while the front interior floor boundary may be around row 205, suggesting that it would land outside. I should not release yet. I’ll continue toward the left link6 target of (-0.345, 0.005, 1.02) m so the contact Y coordinate reaches approximately 0.08 m. The remaining Y difference is 0.093 m, and I estimate that another 5 control steps may be needed. For the right arm, the final tilted placement pose at (0.30, 0, 1.06) m with quaternion [0.812, 0, 0.4799, 0.3321] in wxyz order is about 0.295 m from its measured position of (0.036, -0.121, 0.965) m, exceeding the 0.25 m target-distance limit. I’ll first use an intermediate pose at (0.16, -0.10, 1.04) m, about 0.15 m away. The change from the downward orientation to this tilt is approximately 0.838 rad and looks safe. From that intermediate pose, the final target would be about 0.17 m away. The right watch is held directly by its case. Its proposed path passes in front of the blue basket. At link6 height 1.04 m, I estimate the contact height as 1.04 - 0.14 = 0.90 m and the band bottom as 0.90 - 0.05 = 0.85 m, barely above the estimated rim height of 0.84 m. That looks sufficient, so I’ll lift from the current height of 0.965 m while moving toward the intermediate pose and tilted orientation. Both arms’ motions are independent. I’ll use 6 control steps, keeping both grippers closed while the left continues toward its placement target and the right carries the watch toward the red basket.

The left arm has nearly reached its target orientation, and its measured link6 position is (-0.358, -0.043, 1.026) m. Using the estimated contact offset of (0.045, 0.075, -0.109) m puts the purple bar’s contact point at (-0.313, 0.032, 0.917) m. After dropping to the basket floor at y = 0.032 m, it would project near row 196 in the high-camera image, perhaps inside the white basket’s front interior. I am uncertain whether the floor boundary is near image row 190; an object Y target of 0.05 m would be safer. Reaching the planned link6 Y target of 0.005 m should put the contact Y coordinate near 0.08 m, so I’ll continue toward that pose rather than release yet. The right arm has not reached its intermediate target but still holds the watch by its case. I considered another 3 control steps for the left and 4 for the right toward (0.16, -0.10, 1.04) m, followed by the final red-basket approach. I’ll use 4 shared control steps for both arms now.

I estimate the purple bar’s contact point at y = 0.07 m, which looks suitable for release with the white basket floor directly beneath it. The right arm is still carrying the middle watch toward its intermediate link6 target of (0.16, -0.10, 1.04) m. The watch case is hidden, but I believe it remains held. I’m considering 3 control steps to release the purple bar while continuing the right arm’s motion for 4 steps.

The purple bar is stable inside the white basket, bringing my count to four sorted objects. The right gripper still holds the middle watch. I’ll move it toward the red-basket placement target at (0.30, 0, 1.06) m from its measured position of (0.135, -0.103, 1.028) m. I estimate the position distance as 0.195 m. Its current quaternion is [0.8, -0.001, 0.549, 0.242], and the desired tilted quaternion is approximately [0.812, 0, 0.480, 0.332], both in wxyz order, with an estimated orientation difference of 0.225 rad. Two peppers remain for the left arm, and the red chocolate remains on the right. I could approach the left yellow pepper at (-0.27, -0.163) m in XY or the middle yellow pepper at (-0.14, -0.162) m. I’ll choose the left yellow pepper first, then use a tilted placement into the blue basket after grasping it. The green pepper and purple bar have been removed from the nearby area, leaving only the middle yellow pepper to its right. With that pepper at x = -0.14 m, an estimated separation of 0.13 m, and an estimated finger gap of 0.08 m, closing along world X also looks safe. Could I use an X-closing orientation, and what would its distance from the current tilt be? Another option is the previous purple-bar grasp quaternion [0.666, 0.307, 0.626, -0.267], which points nearly downward and closes diagonally. However, the downward orientation that closes along world Y worked well for the green pepper and avoids the middle yellow pepper, so I’ll use it again. The open left gripper is currently at (-0.347, -0.005, 1.02) m with quaternion approximately [0.812, 0, 0.480, 0.332]. I’ll target (-0.27, -0.163, 1.025) m with quaternion [0.707, 0, 0.707, 0] in wxyz order. My quaternion dot-product estimate is 0.574 + 0.339 = 0.913, giving an orientation distance of about 0.83 rad, within the 1 rad limit. I estimate the position distance as 0.184 m and expect the pose to be reachable. The left approach remains above the table with the gripper open, while the right carries the watch toward (0.30, 0, 1.06) m with clearance above the blue and red basket rims. I’ll execute both motions together for 8 control steps.

The right wrist view shows the red basket floor with the first watch resting inside. The second watch’s case still appears pinched near the bottom of the view, although only a small part of its band is visible. The right link6 is at (0.183, -0.072, 1.04) m with the tilted orientation. Using the estimated contact offset of (0.045, 0.075, -0.109) m gives a case position of approximately (0.228, 0.003, 0.931) m. Relative to the red basket’s estimated center at x = 0.3 m, y = 0.08 m, the case is near the front-left. Could the band loop trail from the case toward y = -0.04 m? I should continue toward the right link6 target with x = 0.30 m and y = 0 m, which would put the estimated case XY position at (0.345, 0.075) m, farther inside. I’ll continue the right motion for 8 control steps. The left arm is at XY coordinates (-0.301, -0.097) m, short of its yellow-pepper approach target at (-0.27, -0.163) m, and its orientation is only partly aligned. I considered another 6 steps for the left approach, but I’ll use 8 shared control steps for both arms.

The middle watch’s band is not visible in the right wrist view; I can only see the first watch’s strap on the basket floor. The held case appears between the pads near the bottom, and its band may be hidden behind the fingers. The case is near the gripper’s contact region at image row 330, with the red basket floor beneath it. Releasing now will likely let the middle watch drop inside near the first watch. The left yellow pepper appears centered near pixel (345, 170). I’ll lower the left link6 to a pregrasp height of 0.975 m, then later to 0.932 m, as I did for the green pepper. I considered 3 control steps for the right release and 4 for the left descent; I’ll use 4 shared steps, opening the right gripper while lowering the open left gripper.

I cannot clearly see the middle watch in the red basket. In the high-camera view, I can identify only the first watch’s strap near pixel (428, 190). The right opening command is 0.967, nearly fully open, but the middle watch’s case might still be between the fingers above the floor. The right wrist view also shows the first watch near the bottom of the basket floor, but not the second. It may have dropped near the front wall and be occluded by the arm; a possible white case near pixel (500, 197) could be beneath the gripper. The basket’s right front edge is around pixel (500, 190). I think the watch is likely inside, but I need to withdraw the right arm and inspect again. The red chocolate’s earlier estimated XY position is (0.423, -0.144) m. It remains near pixel (520, 261) in the high-camera view, with no apparent movement. The right link6 is currently at (0.29, -0.009, 1.057) m with the gripper tilted and commanded open. I’ll move it to the chocolate approach pose at (0.423, -0.144, 1.02) m and restore the downward orientation that closes along world Y. I estimate the orientation change as 0.838 rad and the position distance as 0.198 m. This motion will also clear the basket view for the placement check. The left arm will continue descending around the yellow pepper, from its measured link6 height of 0.981 m toward 0.932 m. I considered 3 steps for that descent, which might bring the measured height to about 0.94 m, and 6 steps for the right approach. I’ll use 5 shared control steps with both grippers commanded open.

In the high-camera view, I can still see only the first watch in the red basket, near pixel (428, 190). The second, middle watch is also no longer visible on the table. It could be inside the red basket but hidden behind the front or right wall, perhaps under the front wall’s lip. If it is lying flat on the floor, I would expect to see it because much of the interior is visible. Alternatively, it may have slipped outside behind the basket or beneath the right arm. Its final location remains unverified. The right wrist view in obs_000395 shows the first watch near the front of the red basket, at the bottom of the image. The second watch may be farther back and outside that camera’s view. I’ll inspect again after the right arm moves farther away and use another viewing angle if needed. I need to keep track of this unresolved placement. Native success is still false, which is expected while other objects remain to be sorted; the final native outcome will confirm overall success. The left yellow pepper is now at the grasp position. I’ll close the left gripper around it while the right continues toward its red-chocolate approach target, using 4 control steps.

The red chocolate is visible near pixel (475, 120) in the right wrist view. Moving the right arm to the approach target at x = 0.423 m, y = -0.144 m should center it over the bar. The left pepper grasp looks secure, with an opening command of 0.431, so I’ll test-lift it to a link6 height of 0.973 m. I considered 6 control steps to finish the right approach, but I’ll use 5 shared steps for both motions.

The yellow pepper moved from approximately pixel (181, 267) to (178, 262) in the high-camera view, an upward shift of 5 pixels, so I judge the grasp secure. The red chocolate is centered near pixel (340, 150) in the right wrist view, with its long axis appearing vertical there and aligned with world X. I’ll lower the right link6 first to z = 0.94 m, then to 0.923 m. Since the bar is slightly right of the image center, I’m considering a 0.004 m correction along negative world Y, giving the next right target of (0.423, -0.148, 0.94) m. The left link6 is currently at (-0.27, -0.163, 0.973) m with a top-down orientation. I estimate the pepper’s bottom height as 0.973 - 0.14 - 0.04 = 0.793 m, so it needs more clearance before transport. I initially considered lifting to z = 1.05 m while tilting to quaternion [0.812, 0, 0.4799, 0.3321] in wxyz order, an orientation change of about 0.838 rad, and moving through (-0.18, -0.06, 1.04) m as I did with the green pepper. Another candidate is (-0.18, -0.06, 1.06) m, which I estimate is 0.144 m from the current pose and would raise the pepper’s bottom to about 0.88 m. Is that reachable? The earlier target at (-0.18, -0.06, 1.04) m passed with a top-down orientation; it may also pass with this tilt. I’ll use the left target (-0.18, -0.06, 1.04) m directly with the tilted quaternion. I estimate its position distance as 0.156 m and the pepper’s bottom at that target as 0.89 m, giving safe clearance. Afterward, I can continue to the blue-basket placement pose at (-0.05, -0.035, 0.99) m with the same tilt, as for the green pepper. I considered 4 steps for the right descent and 5 for the left transport; I’ll execute both together for 5 control steps, keeping the left gripper closed and the right open.

The red bar appears centered near pixel (340, 200) in the right wrist view, with the right link6 at a pregrasp height of 0.964 m. I should lower it to 0.923 m and make a small Y correction; I’m considering y = -0.152 m because the bar remains slightly right of the closing center. At the current height of 0.964 m, I estimate the object’s top at 0.775 m and its distance along local +X at about 0.19 m, corresponding to image y ≈ 200 pixels. At the final height of 0.923 m, that distance would be about 0.148 m, corresponding to image y ≈ 300 pixels. I’ll target the right link6 at (0.423, -0.15, 0.923) m with the gripper open, while the left continues toward (-0.18, -0.06, 1.04) m holding the pepper. I considered 3 control steps for the right descent and 5 for the left transport; I’ll use 4 shared steps.

The red chocolate bar appears centered at pixel (330, 270), and its contact alignment looks good. I’ll close the right gripper. I considered 3 control steps for closure and perhaps 5 for the left arm to continue toward its intermediate pepper-transfer pose; I’ll use 4 shared control steps.

The right pads appear to have stable contact with the red chocolate. I’ll test the grasp with a 0.04 m vertical lift to a link6 height of 0.965 m. For the left arm, I’ll skip the remaining intermediate pose and move directly toward the blue-basket release target at (-0.05, -0.035, 0.99) m. From its current position of (-0.198, -0.08, 1.027) m, I estimate the target distance as 0.158 m. The current quaternion is [0.801, 0, 0.543, 0.252], and the tilted target is approximately [0.812, 0, 0.480, 0.332], both in wxyz order, with an estimated orientation difference of 0.20 rad. At that target, I estimate the pepper’s contact point at x = -0.05 + 0.045 = -0.005 m, y = 0.04 m, and z = 0.881 m, which should place it directly over the blue basket. I considered 4 control steps for the right test lift and 6 for the left placement approach. I’ll use 6 shared control steps for both motions.

The red bar stayed fixed in the right wrist view after the lift, so I judge the grasp secure. The yellow pepper appears near pixel (267, 180) in the high-camera view, over the blue basket’s front-left area, but it has not reached the final placement pose. I’ll continue the left arm toward its target at (-0.05, -0.035, 0.99) m for 6 control steps. The right link6 is at (0.423, -0.15, 0.965) m, holding the red chocolate. I’ll stage it centrally so the left arm can finish placing it in the left basket, as it did with the gold bar. The transfer approach at (-0.05, -0.25, 1.0) m is about 0.49 m away, so I need intermediate poses at (0.25, -0.20, 1.02) m and (0.10, -0.18, 1.02) m before reaching the transfer point and setting it down. A direct handoff to the left arm near the center might also work, but the staging method has already worked, so I’ll repeat it. For this action, I’ll move the right arm toward (0.25, -0.20, 1.02) m while the left finishes positioning the pepper. I estimate the right move as 0.181 m and the held bar’s bottom at the target as z = 0.87 m, safely above the table. I’ll keep both grippers closed and use 6 control steps for both arms.

The left link6 is nearly at its placement target, at (-0.061, -0.04, 0.991) m. I estimate the yellow pepper’s contact point at (-0.016, 0.035, 0.882) m, above the left side of the blue basket and within its footprint. The green pepper is near the basket’s center-right, so the yellow pepper should land to its left. I’ll release the left gripper now while the right continues carrying the red chocolate toward its transfer target at (0.25, -0.20, 1.02) m, using 4 control steps.

The yellow pepper is stable in the blue basket, bringing my count to five sorted objects. The middle yellow pepper remains on the table, the red chocolate is held by the right gripper, and the second watch’s placement is still uncertain, though it is likely inside the red basket. I’ll continue. The remaining pepper is estimated at XY coordinates (-0.14, -0.162) m, with its body top at z = 0.804 m. The left link6 is currently at (-0.061, -0.04, 0.991) m, with the gripper tilted and open. I’ll move it to (-0.14, -0.162, 1.025) m and rotate to the downward orientation that closes along world Y. I estimate the position distance as 0.149 m and the orientation change as 0.838 rad. The right arm will carry the red chocolate toward the intermediate transfer pose (0.10, -0.18, 1.02) m from its measured position of (0.289, -0.191, 1.008) m, an estimated distance of 0.19 m. These approach motions look safe, and I’ll use six control steps for both. I initially considered descending the left arm to grasp the pepper while the right moves toward the transfer point at (-0.05, -0.25, 1.0) m. The staging area should be clear because the gold bar has been picked up. Along that route, I estimate the held red bar’s bottom at z = 0.86 m, above the pepper at about z = 0.81 m, leaving 0.05 m of clearance. However, the arms could come too close during simultaneous manipulation. With left link6 at (-0.14, -0.162, 0.94) m and right link6 at (-0.05, -0.25, 1.0) m, I estimate their separation as 0.128 m. The grippers are about 0.08 m wide, and the separations of 0.088 m along Y, 0.09 m along X, and 0.06 m along Z could still allow the fingers to approach each other. I’ll therefore keep the left arm high while the right completes the transfer and descends to stage the bar. After the right releases it and retreats, the left can descend to grasp the pepper.

The left wrist view shows the peppers already placed in the blue basket and a watch on the table at the right edge. The remaining yellow pepper is not yet visible in that view because the left end effector is still moving toward it. I’ll continue toward the same left approach target and the right transfer approach target at x = 0.10 m for 8 control steps.

The remaining pepper appears at approximately pixel (420, 250) in the left wrist view. It is not centered yet because the left gripper has not fully reached the downward orientation that closes along world Y or its exact approach position. I’ll continue toward the same left target and move the right gripper from XY coordinates (0.105, -0.181) m toward the transfer pose (-0.05, -0.25, 1.0) m. I estimate that move as 0.171 m and expect it to pass the precheck. The arms will come close near the central staging area, so I need to consider possible collisions while keeping the left link6 high at z = 1.025 m and the right target at z = 1.0 m. At the proposed left XY position (-0.14, -0.162) m and right XY position (-0.05, -0.25) m, I estimate their separation as 0.126 m, with a right-minus-left displacement of (0.09, -0.088, -0.025) m. The arms appear near each other in the high-camera view, and their current gripper orientations differ. With the fingers pointing downward and an estimated open spacing of ±0.04 m along world Y, one left finger would be at y = -0.202 m and the nearest right finger at y = -0.21 m. That leaves only 0.008 m along Y, but 0.09 m along X. With finger-body thickness along X estimated at 0.015 m, I judge that clearance sufficient. The arm links could still be close, although the estimated center separation of 0.126 m exceeds the gripper widths. The red bar’s long axis is along world X, and I estimate that it spans x = -0.10 to 0 m while held at the transfer point. The left gripper at x = -0.14 m would be about 0.04 m from the nearest bar end, which looks acceptable. A later right descent to z = 0.916 m while the left stays high would retain my estimated separation of 0.126 m and give a vertical separation of 0.109 m. I think the plan is safe enough to proceed cautiously. I’ll use 4 control steps for both the continued left alignment and the right transfer, then inspect the result before lowering the left gripper.

The latest right wrist view shows a watch on the table to the left, near pixel (130, 260), while the red chocolate remains held. Is this the middle watch? There were two watches initially: the left watch was estimated at XY coordinates (0.023, -0.113) m and the right watch at (0.314, -0.093) m. I placed the right watch first, then believed I had grasped the middle watch near its estimated case position of (0.036, -0.121) m and placed it in the red basket. Yet obs_000451 clearly shows a watch still on the table near high-camera pixel (317, 246), and only one watch was visible in the red basket after the second placement attempt. Could this be a third watch? My initial count was two. Looking back, the table watch was still near (317, 246) in obs_000433 after the second release. Perhaps I grasped the left watch and it somehow fell back to the same table location. However, it may never have been grasped at all. In obs_000356, it appeared near high-camera pixel (320, 244), under the right gripper, without clear movement. I assumed it was held because the wrist view appeared to show the case pinched, but the gripper may have closed empty beside it and then traveled to the red basket without the watch. That would explain both the remaining table watch and the absence of a clearly visible second watch in the basket. The case remained visible in the wrist camera during the supposed test lift, but a stationary table object would also remain in view as the camera rose. Its apparent size was about 60 pixels in obs_000352 and still about 60 pixels after the lift in obs_000356, which seemed consistent with a grasp, although perspective or orientation may have obscured the difference. The unchanged high-camera position near (320, 244) suggests that it did not lift. I need to treat the watch on the table as unplaced. The remaining work includes the yellow pepper, red chocolate, and watch, and native_success is false. The current wrist view clearly shows the remaining watch’s clock face on the table. I now suspect the second watch was never grasped, perhaps because I targeted the buckle or misinterpreted the camera view. After staging the red bar, the right arm can regrasp this watch and verify clear movement in the high-camera view. Using the left arm is another possibility, but the right can handle it after staging. A direct grasp on the rigid case with a different orientation should be more robust. There are 649 control steps left, which should be enough. I must verify that both watches end up in the red basket and explicitly track this table watch until it moves with the gripper. Grasping the whole watch by the band while securing the case is another option, but the successful first-watch attempt used a direct case grasp and showed high-camera movement from approximately (490, 232) to (490, 210) during the tilt. The second attempt may have failed because the estimated case XY position of (0.036, -0.121) m was wrong; perhaps its actual world X coordinate was closer to 0.005 m. I may have matched the wrong features during triangulation again. I’ll localize the visible clock face now while the right gripper holds the red bar. In obs_000451, I estimate the face at right-wrist pixel (136, 238), the white case at (135, 240), and the band-ring center at (130, 265). The face may be near high-camera pixel (317, 244). I’ll try triangulating the matching feature at high-camera pixel (318, 244) and right-wrist pixel (135, 240), using the measured right link6 position of (0.049, -0.208, 1.011) m and its downward orientation that closes along world Y. If these features correspond correctly, the calculation should give a more accurate case position.

I’ll inspect the enlarged head-camera crop of the remaining watch to identify its case and clarify its apparent contact with the table. Matching that feature with the wrist view should help refine the uncertain grasp height before lowering the gripper.

I identify the watch case in the head-camera view as the white rectangle at the upper-left of the ring. Its estimated position in the enlarged crop is (130, 110) pixels, corresponding to original-image coordinates x = 290 + 21.7 = 311.7 pixels and y = 225 + 18.3 = 243.3 pixels. The corresponding case in the right wrist image may be near (135, 240) pixels. I’ll inspect the enlarged wrist crop to check that correspondence.

The watch case is the white rectangle at the upper-left of the ring in the head-camera view, near pixel (312, 243), rather than x = 318. I estimate its center at (445, 220) pixels in the enlarged right wrist crop. This corresponds to original-image coordinates x = 60 + 74.2 = 134.2 pixels and y = 200 + 36.7 = 236.7 pixels. I’ll use (312, 243) in the head view and (134, 237) in the right wrist view for triangulation. My earlier head-view x estimate was off by 6 pixels, and the wrist-view y estimate was off by 3 pixels.

The latest triangulation gives an even lower height, z ≈ 0.718 m, which seems implausible. Something may be wrong with the feature correspondence or calibration. The watch face is estimated at (134, 237) pixels in the right wrist image, but its counterpart in the head view may be on the right side of the ring rather than at the upper-left. The upper-left white rectangle in the head-camera crop appears to have a brown center. Could it be a buckle with holes rather than the case? The case face should show clock hands, although they may not be visible in that view. The vertical white feature on the right, near (332, 246) pixels, might instead be the case edge. The case appears at the top of the ring in the wrist view, but its orientation could make it appear on the right in the head view. I still need to determine which feature corresponds to the wrist-view case. I’ll use the triangulation residuals to help assess the candidate correspondences. Pairing head-camera pixel (336, 245) with wrist-camera pixel (134, 237) might give z ≈ 0.79 m and a low residual, as the earlier right-side candidates did. I’ll test that possibility.

The head-camera vertical residual remains about 5 pixels regardless of the horizontal coordinate, so I still do not have an exact feature match. Could the wrist-image vertical coordinate be wrong, or could there be a camera-calibration issue? I’ll try increasing the head-image vertical coordinate to 250 pixels to reduce the residual. At a candidate point such as (334, 250), I’m unsure how small the residual would become or whether the estimated z coordinate would remain the same. I’ll test this.

Matching the watch case at head-camera pixel (332, 250) gives an almost perfect fit and an estimated position of (0.0243, -0.1362, 0.7932) m. Pixel row 250 plausibly corresponds to the lower part of the right-side white case. Could its center be at (332, 250)? I estimate that white feature near x ≈ 230 pixels in the enlarged crop, mapping to original-image x = 290 + 38 = 328 pixels. I am unsure of its vertical offset from the crop origin at y = 225 pixels, though its bottom appears near row 256. Another possible center estimate is (330, 249). I now take the case position to be approximately (0.024, -0.136, 0.793) m rather than (0.036, -0.121, 0.777) m. The previous grasp at link6 position (0.036, -0.121, 0.926) m was offset by about +0.015 m along Y. Its estimated contact height was 0.786 m, close to the case height of 0.793 m, so why did it not grasp? Contact 7 mm below the estimated case top should have allowed a pinch, and the 0.015 m Y offset might still fit within an estimated case width of 0.03 m. Yet the head view did not show a lift. The alternative upper-left feature at pixel (312, 250) triangulates to (-0.0186, -0.0957, 0.7178) m, which seems implausible with the table at z = 0.75 m, so I identify the right-side feature as the case. Its estimated height above the table is 0.043 m, suggesting an upright watch rather than a flat one. The face looks angled upward in the wrist view; is the band loop vertical, with the case at its top? The previous contact-height calculation, 0.926 - 0.14 = 0.786 m, does not clearly explain the failure. Perhaps closing along world Y missed the case because of the X and Y offsets or its long-axis alignment. Later I’ll target it more precisely, possibly lower link6 to 0.915 m, and verify the lift in the head view. First I’ll finish staging the red chocolate and handling the last yellow pepper. The right link6 is at (0.049, -0.208, 1.011) m. I’ll move it to (-0.05, -0.25, 0.916) m with the red bar held, a descent of 0.095 m. I estimate the target distance from the current pose as 0.162 m, which is acceptable. The pepper appears centered near pixel (350, 165), and I’ll hold the left arm high at z = 1.025 m without moving it. I’ll use 6 control steps for the right staging motion, then release the bar and retract the right arm before descending with the left.

The right link6 is at (-0.014, -0.232, 0.96) m and has not yet reached its target. The red bar still appears high above the table, near pixel (285, 292). I’ll continue toward the right target of (-0.05, -0.25, 0.916) m for 4 control steps while holding the left arm above the pepper. The arms are close, but I see no collision. The right wrist view shows the watch on the left and the yellow pepper at the bottom, leaving the central staging area clear.

The right link6 barely changed height, from z = 0.96 m to 0.962 m, despite the target of 0.916 m, and its x coordinate has only reached -0.028 m. Could a collision with the left arm be slowing it? The arms appear close or possibly touching near the center in the high-camera view, and I wonder whether the right upper arm lies across the left gripper. The white right forearm extends to approximately pixel (270, 230), while the black left gripper is near (220, 260); they look close but not in contact. Alternatively, local IK or joint limits, orientation drift, and the cross-table reach at this low height may explain the slow movement. The target (-0.05, -0.25, 0.916) m may be near a limit, with the measured pose stalled around (-0.028, -0.234, 0.962) m. Is the red bar already near table height? Its center remains near wrist-image row 260, and it appears near pixel (285, 295) in the high-camera view. The opening command is 0.185, and the gripper appears to maintain contact. I could release at the current XY position, (-0.028, -0.234) m, with an estimated 2 cm drop onto the clear transfer area; reaching the exact target is unnecessary. I am still uncertain whether the bar’s bottom is near z = 0.75 m or whether its center is about 0.18 m along local +X from link6. The bar looks large in the wrist view, with its bottom near row 430, similar to its appearance during the grasp at link6 z = 0.925 m, suggesting that its position relative to link6 has stayed fixed. It was on the table at that initial grasp height. After lifting to 0.965 m and transporting it, link6 is now at 0.962 m, so I estimate the bar’s bottom is 0.037 m above its original table position. A 3.7 cm drop should be safe. I’ll open the right gripper at its current measured pose for 3 control steps while keeping the left above the pepper. After releasing the bar, I can retract the right arm upward and away toward the remaining watch. The left can descend once the right has opened and moved clear.

The released red bar appears stable on the table at pixel (288, 302). The right gripper is open near it, and the left gripper remains high above the last pepper. The pepper’s image center is approximately (345, 150) pixels, which looks suitable for the approach. I’ll retract the open right gripper to (0.15, -0.20, 1.04) m with the downward orientation that closes along world Y, while lowering the open left gripper to (-0.14, -0.162, 0.975) m. The right will move rightward and upward as the left descends, increasing their separation, so I judge the simultaneous motion safe. From the measured right position of (-0.027, -0.233, 0.968) m, I estimate the target distance as 0.189 m. Its current quaternion is [0.686, 0.022, 0.727, 0.005] in wxyz order, about 0.07 rad from the nominal downward orientation. I considered 4 control steps for the left descent and 6 for the right retreat; I’ll use 5 shared steps.

The remaining watch face is clearly visible at wrist-image pixel (85, 245), while its high-camera position remains unchanged at (317, 246). The right link6 is currently at (0.044, -0.221, 0.997) m. With the downward orientation that closes along world Y, optical X is opposite world Y. Using an estimated camera depth of 0.13 m, the horizontal offset of 320 - 85 = 235 pixels gives a positive relative local Y coordinate of about 0.077 m and optical X of about -0.077 m. Since local Y aligns with world Y, this estimates the case’s world Y coordinate as -0.221 + 0.077 = -0.144 m, close to the earlier estimate of -0.136 m. The vertical projection also supports the case’s estimated X coordinate. Assuming case z = 0.793 m and link6 z = 0.997 m gives a local X distance of 0.204 m. The relative local Z coordinate, which corresponds to world X here, is still unknown. The camera equations give optical Z = 0.866 × 0.204 - 0.5 × local Z - 0.048 = 0.129 - 0.5 × local Z, and optical Y = -0.102 - 0.866 × local Z + 0.087 = -0.015 - 0.866 × local Z. For image row 245, (245 - 240) / f = 0.0126, so optical Y is approximately 0.0016 m at the estimated depth. This gives local Z ≈ -0.0192 m and object world X ≈ 0.044 - 0.0192 = 0.025 m. The resulting estimate, approximately (0.025, -0.144, 0.793) m, is consistent with the earlier close triangulation fit using high-camera pixel (332, 250). I’ll retain the case target estimate of (0.024, -0.136, 0.793) m; the current wrist geometry supports a Y coordinate near -0.14 m. For a case grasp with contact 0.14 m along local +X, I would target link6 at (0.024, -0.136, 0.933) m. First I’ll approach at (0.024, -0.136, 1.02) m, then descend toward z = 0.93 m. The previous attempt targeted (0.036, -0.121, 0.926) m, offset by +0.012 m along X and +0.015 m along Y, with a slightly lower height. It might still have grasped, but the more precise target should improve the next attempt. Is the case face flat or tilted upward, and is the band loop vertical? The face appears almost parallel to the wrist image plane, with its normal toward the camera, apparently at the top of an upright band. Its estimated z = 0.793 m is 0.043 m above the estimated table height of 0.75 m. The case appears roughly 70 × 60 pixels, and the downward, world-Y closing direction should move the pads horizontally across its width. I expect this centered grasp to lift it, but that will need verification. The left link6 is at z = 0.976 m and can descend toward the last pepper’s grasp height of 0.932 m. Meanwhile, the right can approach the watch at (0.024, -0.136, 1.02) m; I estimate that move as 0.104 m and judge it safe. I’ll execute both motions for 4 control steps with both grippers open.

The last pepper is ready for grasping, so I’ll close the left gripper. The right arm is still at y = -0.187 m, short of its target y = -0.136 m, so I’ll continue its approach over the watch case. I’m considering 3 control steps for the left closure and 5 for the right arm to continue toward its target.

The watch case appears centered at pixel (245, 210) in the right wrist view. The right link6 has not yet reached its XY target of (0.024, -0.136) m; its measured Y coordinate is still -0.159 m. Would moving along positive world Y shift the case left in the image? Optical X points opposite world Y. With the case at estimated world y = -0.136 m and link6 at y = -0.159 m, the relative Y offset is +0.023 m, consistent with an image X coordinate below 320 pixels, currently about 245. Once link6 reaches the same Y coordinate as the case, I expect the case to be centered at image x = 320 pixels. I’ll continue the right arm toward its existing target while test-lifting the last pepper with the left arm to a link6 height of 0.974 m. I’ll use 4 control steps.

The watch case now appears at pixel (300, 180) in the right wrist view, with the ring center near (290, 210). With the right link6 at approximately (0.025, -0.138) m in XY and the case estimated at (0.024, -0.136) m, I expected the case at image x = 320 pixels. The observed x = 300 pixels is a small offset, so I’m considering adjusting the target Y coordinate to -0.134 m. The vertical projection supports the localization. The right link6 height is 1.019 m and the estimated case height is 0.793 m, giving a distance of 0.226 m along local +X. My camera-coordinate estimates are -0.113 + 0.087 = -0.026 m vertically and 0.196 - 0.048 = 0.148 m in depth, predicting image y ≈ 170 pixels. That matches the observed y = 180 pixels closely enough that I consider the localization correct. A grasp target at link6 z = 0.933 m would put the case 0.14 m along local +X, projecting near image y = 330 pixels. I’m considering the final right grasp target (0.024, -0.134, 0.933) m, with the tentative +0.002 m Y correction from the case’s estimated Y coordinate. I’ll stage the descent through z = 0.95 m, initially considering 4 steps followed by 3 for the final descent. The last pepper has lifted with the left gripper. I’ll transport it from the current top-down pose at (-0.14, -0.162, 0.973) m toward the blue-basket target (-0.05, -0.035, 0.99) m with the tilted orientation. I estimate the target distance as 0.160 m and the orientation change as 0.838 rad, and judge the motion safe. For the immediate action, I’ll use 5 shared control steps to transport the held pepper while lowering the open right gripper toward z = 0.95 m.

The watch case appears centered near pixel (300, 250) in the right wrist view, with the pads well to either side. The right link6 is currently at z = 0.961 m, still above the previous target of 0.95 m, and needs to descend to the final grasp height of 0.933 m. I considered 3 control steps for that descent, but I’ll use 4 shared steps while the left arm continues toward its existing pepper-placement target.

The left gripper’s opening command has unexpectedly fallen to 0.0 from about 0.416 while it remains commanded closed. The last pepper is still visible in the left wrist view, but I am uncertain whether it is held. In the high-camera view, I estimate it near pixel (307, 203), with other estimates of (306, 200) and (307, 202), near the blue basket’s front wall rather than clearly inside. It was near (248, 266) before the lift and has moved toward the basket with the gripper, but it could now be held or resting on the rim. The pepper may have slipped, leaving the fingers closed around nothing, or contact with the blue basket may be squeezing it. It could also have fallen into the basket. Another possibility is that the grasp migrated to the thin stem as the body rotated, explaining the opening command of 0.0. The pepper body remains large at the bottom-right of the wrist view, but the pads are not obvious. Could it be resting on the table? The basket floor contains a yellow pepper on the left; I am unsure whether the pepper on the right near the watch is still held. A stem grasp may still be secure, but I should continue carefully and avoid releasing before it is over the interior. The measured left link6 position is (-0.084, -0.081, 0.975) m, with its rotation still incomplete. Using a tentative contact offset of (0.03, 0.05, -0.11) m gives an object position of approximately (-0.054, -0.031, 0.865) m. That estimated y coordinate of -0.031 m is at the front, outside the floor. I’ll continue toward the left target of (-0.05, -0.035, 0.99) m, which I expect to put the object’s y coordinate near 0.04 m. If the pepper has already dropped, it should remain stationary in the high-camera view; for now, movement with the arm still seems likely. The right watch case is now large and centered near pixel (320, 310), with open fingers on either side. I’ll close directly on it while continuing the left placement approach. I’m considering 3 steps for the right closure and 4 for the left motion.

The right gripper’s opening command is 0.178 rather than 0, and the watch case appears centered between the pads with contact on both sides. This may be a real grasp. The measured right link6 position is (0.034, -0.126, 0.941) m, compared with the commanded target of (0.024, -0.134, 0.933) m. Could contact constraints have displaced the gripper as the fingers pushed the case? I’ll test the grasp with a 0.04 m vertical lift to z = 0.981 m and check for watch movement in the high-camera view. The left arm has barely progressed toward its target. Its orientation has deviated, its position appears stalled, and its opening command is 0. The last pepper appears near pixel (303, 195) on the blue basket’s front wall. It may be trapped between the left gripper and the basket rim, preventing further motion and causing the orientation deviation. The left black gripper and right white arm also appear very close near the center; could an arm-to-arm collision be preventing both from advancing? I should stop the inward motion and assess these possible contacts. A vertical lift could clear the rim and also reveal whether the pepper remains held by its stem. The left link6 is currently at (-0.078, -0.077, 0.977) m with quaternion [0.771, -0.078, 0.59, 0.225] in wxyz order. I’ll hold that orientation and target (-0.078, -0.077, 1.05) m while the right test-lifts the watch to (0.034, -0.126, 0.981) m with its current orientation held steady. The grippers are separated by 0.112 m along X and are at similar heights, although possible contact between the arms remains uncertain. Lifting both together may be acceptable. I’ll keep both grippers commanded closed and use 3 control steps, then inspect which objects move with them.

The left gripper is now clear above the blue basket floor, so I’ll open it to release the last pepper over 3 control steps. The right arm is moving away; I’ll continue toward (0.15, -0.18, 1.05) m, perhaps for the same 3 steps. After the release, the left arm can pick up the staged red chocolate, and the right can prepare a horizontal side grasp on the remaining watch.

All three peppers are inside the blue basket. The left arm still needs to pick up the staged red bar near (-0.028, -0.234) m in XY; its actual center may be near (-0.025, -0.235) m. The remaining watch may have shifted during the grasp attempts. It still appears near head-camera pixel (317, 247), while its face is now near right-wrist pixel (250, 338). The measured right link6 position is (0.126, -0.169, 1.035) m, with the downward orientation that closes along world Y. Assuming the case height is still 0.793 m gives a local X distance of 0.242 m. Letting l denote its relative local Z coordinate, equal to object world X minus 0.126 m, the camera equations give optical Z = 0.866 × 0.242 - 0.5l - 0.048 = 0.1615 - 0.5l and optical Y = -0.121 - 0.866l + 0.087 = -0.034 - 0.866l. At image row 338, 98/397 = 0.247, so -0.034 - 0.866l = 0.247(0.1615 - 0.5l) = 0.0399 - 0.1235l. Thus, -0.0739 = 0.7425l, giving l = -0.0995 m and object world X = 0.0265 m. The resulting camera depth is 0.2113 m. Optical X = -local Y = (-70/397) × 0.2113 = -0.0373 m, so local Y = 0.0373 m and object world Y = -0.169 + 0.0373 = -0.1317 m. This gives an updated case estimate of approximately (0.0265, -0.132, 0.793) m, consistent with the earlier estimate. For a horizontal side grasp, I can return toward the initial quaternion [0.707, 0, 0, 0.707] in wxyz order. Local X then points along world +Y and local Y along world -X. I briefly questioned whether local Z pointed along world -Y or required a negative world-Z term, but the Z-rotation matrix gives local Z along world +Z. The fixed camera mapping is therefore optical X = world X, optical Y = -0.5 world Y - 0.866 world Z + 0.087, and optical Z = 0.866 world Y - 0.5 world Z - 0.048, using coordinates relative to link6. The camera's local position of x = 0.0848 m and z = 0.0509 m becomes a world offset of +0.0848 m along Y and +0.0509 m along Z. It looks forward along +Y and downward at 30 degrees. A case positioned at local coordinates (0.14, 0, 0) m should project to pixel (320, 330). Subtracting 0.14 m along world Y from the case position gives a horizontal grasp target of approximately (0.0265, -0.2717, 0.793) m for link6. I estimate the fingertips at local X = 0.1576 m would reach world y = -0.1141 m, extending 0.0176 m beyond the case, with the pads surrounding it. The fingers would be horizontal at z = 0.793 m, leaving 0.043 m above the estimated table height of 0.75 m. Opening along world -X should leave the fingers on either side of the case and clear of the band. An approach at link6 y = -0.31 m and z = 0.82 m is another possibility. I estimate the object's relative local X as 0.1783 m and local Z as 0.027 m, but have not determined its camera projection there. I should first rotate in clear space at z = 0.95 m, above and behind the watch near y = -0.28 m, then descend to the case height of 0.793 m at a pregrasp Y coordinate of -0.30 m and advance toward -0.272 m. The horizontal fingers should remain above the table at that height. Link6 and the wrist would be low, but this seems likely to be reachable near y = -0.28 m, given the initial link6 height of 0.9215 m. The rotation from the downward orientation to the initial Z-rotation is 2.094 rad, so I need increments of about 0.8 rad. I initially considered rotating while moving the right arm to (0.026, -0.30, 0.95) m, an estimated distance of 0.169 m from its measured pose. For spherical interpolation, a fraction of 0.38 would give about 0.8 rad. Earlier fractions of 0.35 and 0.4 produced quaternions [0.806444, 0, 0.513838, 0.292606] and [0.812024, 0, 0.479925, 0.332099], respectively; I estimate the 0.38 quaternion as approximately [0.8102, 0, 0.4932, 0.3174]. I can use either 0.38 or 0.4; the latter gives a 0.838 rad increment. Meanwhile, the left can approach the red bar at (-0.028, -0.234, 1.02) m with the downward quaternion [0.707107, 0, 0.707107, 0]. From its measured position of (-0.053, -0.04, 1.019) m, I estimate a distance of 0.195 m. Its current quaternion is [0.805, -0.019, 0.508, 0.307]; the dot product with the downward goal is approximately 0.569 + 0.359 = 0.928, giving a rotation distance of 0.755 rad, within the command limit. However, the proposed simultaneous targets would put the left near x = -0.03 m and the right near x = 0.026 m, with Y coordinates of -0.234 and -0.30 m. I estimate about 0.083 m of horizontal separation and 0.099 m between the full link6 positions, so the open grippers could collide. I should stagger the approaches. Instead, I’ll rotate the right arm at (0.15, -0.30, 0.95) m, keeping it farther from the left while the left approaches the staged bar. I estimate that right move as 0.132 m and the separation from the left target as about 0.19 m, which looks safe. After the left picks up the red bar and moves toward the white basket, the right can approach the watch near x = 0.026 m. I’ll use seven control steps now, with both grippers open and the right using the 0.4 interpolation quaternion.

The staged red bar is not yet visible in the left wrist view. Near the top of that view, I seem to see a watch ring with a white case on the blue basket’s wall or floor. Could it be the remaining watch, or could the second watch have landed in the blue basket? The high-camera view shows peppers there but no visible watch. Perhaps the wrist view shows the remaining table watch through or behind the basket, or a reflection of it. Another possibility is a printed watch outline or target icon on the basket base. I previously noticed a rectangular outline on the blue floor, whereas this now looks like a ring. I have not noticed such icons in the white basket, which contains the purple and gold bars. This interpretation remains unresolved, and I’ll leave it for now. The right arm’s rotation is progressing. I’ll continue toward the same targets for 8 control steps.

The staged red bar appears centered at pixel (335, 170) in the left wrist view. I’ll lower the left link6 first to z = 0.94 m, then to 0.923 m. The right gripper is nearly at its tilted orientation and should continue rotating toward the initial 90-degree Z orientation for a horizontal case grasp. The measured right quaternion is [0.802, -0.001, 0.536, 0.264] in wxyz order, and the initial quaternion is approximately [0.707, 0, 0, 0.707]. My estimated dot product is 0.567 + 0.187 = 0.754, giving an orientation distance of 1.426 rad, above the 1 rad command limit. I’ll calculate an intermediate quaternion for a 0.8 rad rotation, corresponding to an interpolation fraction of about 0.56. My tentative estimate is [0.784, 0, 0.358, 0.501], but I’ll compute it before using it. I can keep the right position target at (0.15, -0.30, 0.95) m, since its measured position is nearby, and use the intermediate orientation. I’m planning 4 control steps for the left descent to z = 0.94 m while the right continues its rotation.

The staged red bar is centered beneath the left gripper, so I’ll lower it to pre-grasp height with the fingers open. I’ll also use the calculated intermediate rotation to bring the right gripper closer to the horizontal side grasp planned for the remaining watch case.

The staged red bar appears centered at pixel (335, 235) in the left wrist view, with the left link6 at z = 0.964 m. Where would its image Y coordinate be at the previous target height of 0.94 m? I expect its center to reach image row 330 at z = 0.923 m. I’ll descend to that height and make a small alignment correction: since the bar is at image x = 335 pixels, I’m considering moving the end effector 0.003 m along negative world Y, giving a left target of (-0.028, -0.237, 0.923) m. The right arm’s measured quaternion is [0.816, -0.001, 0.448, 0.366] in wxyz order, still short of the intermediate target of approximately [0.799, -0.0004, 0.254, 0.544]. I considered another 5 control steps toward that orientation, but I’ll use 4 shared steps for the left descent and continued right rotation.

The red bar is ready for the left gripper to close around it. The right arm still needs to continue its rotation toward the same target. I’m planning 3 control steps for the left closure and 5 for the right arm’s continued alignment.

The right wrist is nearly at its intermediate orientation. My estimated dot product with the initial 90-degree Z orientation is 0.813 × 0.707 + 0.483 × 0.707 = 0.916, giving a remaining orientation distance of about 0.83 rad, below the 1 rad command limit. I can now target the final horizontal orientation. The measured right link6 position is (0.148, -0.303, 0.951) m, and that orientation is likely reachable at essentially the same position. I’ll test-lift the red bar with the left arm to a link6 height of 0.964 m while the right completes its rotation. I’ll execute both motions together for 5 control steps.

The red bar shifted slightly in the high-camera view from approximately (288, 302) to (280, 298) pixels during the test lift and stayed fixed relative to the wrist camera, so I judge the grasp secure. The right arm has not yet reached its final horizontal orientation and needs to continue rotating. For the left arm, I’ll use the previously planned tilted placement pose at (-0.345, 0.005, 1.02) m over the white basket. The rotation from the downward, world-Y closing orientation to that tilt is approximately 0.838 rad, but I estimate the position distance as 0.391 m, exceeding the 0.25 m command limit. I’ll first move to (-0.22, -0.14, 1.05) m with the tilted orientation, then continue to the final placement pose. The right arm can finish rotating to the initial 90-degree Z orientation while moving above and behind the watch at (0.026, -0.32, 0.95) m. From its measured position of (0.147, -0.304, 0.952) m, I estimate the position distance as 0.121 m and the orientation change as 0.83 rad. The right arm will move leftward toward the watch while the left moves toward the white basket. I estimate the separation between the proposed left intermediate XY position (-0.22, -0.14) m and right XY position (0.026, -0.32) m as 0.33 m, which looks safe. At the right approach pose, the horizontal fingers will point along world +Y at z = 0.95 m, above the watch case’s estimated height of 0.793 m. After reaching that pose, I can lower to z = 0.82 m while keeping y = -0.32 m, then advance to y = -0.272 m for the side grasp. The final horizontal orientation is likely to pass the precheck at the new position, though that still needs confirmation. I’ll execute both immediate approach motions for 8 control steps, keeping the left gripper closed on the red bar and the right gripper open.

The right gripper is nearly horizontal, and its wrist view shows the watch near the bottom center with the baskets ahead. I’ll continue toward the same right approach target while the left arm continues transporting the red bar, using 8 control steps.

Is the red bar over the front of the white basket yet? The left link6’s current XY position is (-0.208, -0.147) m. Using the tilted grasp’s estimated contact offset of (+0.045, +0.075) m gives an estimated bar XY position of (-0.163, -0.072) m, so it has not yet reached the white basket at x = -0.3 m. I need to move the left arm to its final placement target. The right link6 is at x = 0.044 m rather than its target x = 0.026 m. Its quaternion is close to the initial orientation, and the watch is visible near the bottom center of the wrist view, so the approach looks good. I’ll target the right link6 at (0.026, -0.32, 0.95) m and the left at (-0.345, 0.005, 1.02) m. I estimate the left move as 0.199 m. I’ll execute both motions for 8 control steps, then lower the right gripper for the side grasp and release the red bar with the left.

The left link6 is at x = -0.295 m, y = -0.055 m, and I estimate the red bar’s contact point at x = -0.25 m, y = 0.02 m. The white basket’s center is near x = -0.3 m, so the bar is toward its right side. I could release it now at y = 0.02 m near the front interior, but continuing to the link6 target at x = -0.345 m, y = 0.005 m should position it better. I’ll continue that motion for 4 control steps. The right arm is nearly at its pregrasp pose. Its current quaternion is [0.729, -0.002, 0.043, 0.683] in wxyz order, rather than the exact initial orientation. Local +X seems to point mostly along world Y, perhaps with a downward component. I should finish the horizontal alignment while lowering the gripper. One option is an intermediate position of (0.026, -0.32, 0.85) m. With the initial orientation, the fingers would be horizontal at z = 0.85 m, 0.057 m above the case’s estimated height of 0.793 m. The bottom of the case is partly cut off in the wrist view. I could then lower to z = 0.82 m while keeping y = -0.32 m, before advancing to y = -0.272 m at z = 0.793 m. At z = 0.82 m, would the case be below the fingertips? The fingers would be 0.027 m above the estimated case height. Instead of stopping at 0.85 m, I’ll directly target the pregrasp position (0.026, -0.32, 0.82) m with the initial quaternion. This lowers the target by 0.135 m, with an estimated position distance of 0.135 m and a small orientation change of about 0.12 rad. Although this descent is near the table, I judge the fingers at z = 0.82 m to have clearance. I’ll use 4 control steps for both arms, keeping the left gripper closed and the right open.

The right link6 height appears unchanged at 0.948 m after 4 control steps, despite the target height of 0.82 m, with only slight movement in X and Y. The precheck passed, but could a joint limit be preventing the descent? The horizontal orientation at the lower height might be unreachable, although I would expect the precheck to reject it in that case. Large joint adjustments or continued orientation convergence may instead explain the slow progress; further steps might help. I considered continuing toward the right height target of 0.82 m for 6 steps. The left link6 is at x = -0.325 m, y = -0.021 m, with an estimated red-bar contact point at XY coordinates (-0.28, 0.054) m, which appears inside the white basket over its floor. I’ll release the red bar now while continuing the right approach for 5 control steps. The left arm can retract afterward.

All three chocolates are now inside the white basket, leaving only the remaining watch to manipulate. The right gripper is nearly horizontal, with link6 at z = 0.932 m, still above its target of 0.82 m. The fingers are visible at the lower left and right of the wrist view, and the watch is partly visible at the bottom center. I’ll continue the descent toward 0.82 m for 8 control steps. The left arm can move into clear space while the right works, but I should call robot_reset only after manipulation is complete. I considered retracting it near (-0.35, -0.15, 1.05) m with the downward orientation that closes along world Y, or holding it clear at (-0.35, -0.20, 1.02) m with the initial orientation. Its current open-gripper pose is (-0.325, -0.021, 1.021) m with quaternion [0.812, 0, 0.48, 0.332] in wxyz order. Another option was (-0.35, -0.25, 1.05) m with either the downward or initial orientation. Returning toward the initial 90-degree Z quaternion [0.707, 0, 0, 0.707] would require an intermediate rotation because I estimate the orientation difference from the current tilt as 1.047 rad, above the 1 rad limit. I could also leave the arm open above the white basket temporarily, though it will need clearance before reset. I considered retracting to (-0.35, -0.20, 1.05) m while taking a 0.8 rad intermediate rotation toward the initial orientation. An approximate intermediate quaternion such as [0.8, 0, 0.3, 0.5] would need an exact calculation before use. Instead, I’ll use the known downward quaternion [0.707, 0, 0.707, 0], which I estimate is 0.838 rad from the current orientation, and defer the return orientation until later. This moves the open left gripper away from the basket and the right arm. I estimate the distance to (-0.35, -0.20, 1.05) m as 0.231 m, within the command limit. I’ll execute this clearance motion together with the right descent for 8 control steps, keeping both grippers open.

The horizontal wrist view shows the watch near the bottom of the image, with the case face on the right side of the loop at approximately (280, 405) pixels and the band-loop center near (250, 405). The fingers are open on either side and point forward along world +Y, though I am unsure of their vertical pixel positions. The gripper’s horizontal image center is x = 320 pixels. A contact point 0.14 m along local +X projects to image row 330, so the case at row 405 is below the intended contact region. I need to adjust the gripper’s height and forward position to bring the case into that region. The current right link6 position is (0.028, -0.326, 0.879) m, with the initial orientation. I am using the case-position estimate (0.026, -0.132, 0.793) m. Its relative world coordinates are dx = -0.002 m, dy = 0.194 m, and dz = -0.086 m. With the 90-degree Z orientation, these become local X = 0.194 m, local Y = 0.002 m, and local Z = -0.086 m. The camera-coordinate calculation gives x = -0.002 m, corresponding to image u ≈ 316 pixels; y = -0.5 × 0.194 - 0.866 × (-0.086) + 0.087 = -0.097 + 0.0745 + 0.087 = 0.0645 m; and z = 0.866 × 0.194 - 0.5 × (-0.086) - 0.048 = 0.168 + 0.043 - 0.048 = 0.163 m. The predicted vertical pixel coordinate is 240 + 397 × 0.0645 / 0.163 = 397, which is close to the observed row 405. To place the case at local X = 0.14 m and local Z = 0, I need link6 y = -0.132 - 0.14 = -0.272 m and z = 0.793 m. The case is currently too far forward at local X = 0.194 m, and the gripper is too high, with the case at local Z = -0.086 m. Moving forward along +Y by 0.054 m and downward by 0.086 m to (0.026, -0.272, 0.793) m should bring the case to image row 330, with the fingers at the case’s height. I considered first descending at the current Y coordinate to z = 0.82 m, using local Z = -0.059 m and local X = 0.194 m. The projection calculation gives camera y = -0.097 + 0.051 + 0.087 = 0.041 m and camera z = 0.168 + 0.0295 - 0.048 = 0.1495 m, yielding image row 349. That is near the contact row, but local X = 0.194 m is still beyond the fingertip extent of 0.1576 m, so I would need to advance before grasping. Another option is y = -0.286 m and z = 0.82 m, giving local X = 0.154 m and local Z = -0.027 m. That gives camera y = -0.077 + 0.023 + 0.087 = 0.033 m and camera z = 0.133 + 0.0135 - 0.048 = 0.0985 m, yielding image row 373. I am unsure whether that puts the case below the tip in the image; it still does not give the fully aligned local coordinates. I’ll approach gradually to avoid collision: first move the open right gripper to (0.026, -0.29, 0.82) m, advancing 0.036 m and descending 0.059 m over 3 control steps, then inspect. Afterward, I can consider a 2-step move to the final target (0.026, -0.272, 0.793) m. The estimated open finger gap along world X is 0.08 m, and the band’s estimated X range is [-0.005, 0.055] m around the case at x = 0.026 m, so it should fit. At the intermediate pose, the fingertips would reach y = -0.29 + 0.1576 = -0.1324 m, approximately the case’s Y coordinate, but at z = 0.82 m they would remain 0.027 m above the case. I am unsure of the pads’ vertical span; the fingers may be about 0.01 m thick vertically and still above it. At the final pose, the tips would reach y = -0.114 m, with the case 0.14 m along local +X. While the right approaches, the left arm can continue withdrawing toward its clear-space target (-0.35, -0.20, 1.05) m. I’ll use 3 control steps for this immediate action.

The watch case still appears near pixel (280, 400), on the right side of the band loop, which now looks larger. The left and right fingertips appear around image rows 270–400, with the case near row 400 at the ends of the pads. I’ll move the right link6 from its measured position of (0.028, -0.311, 0.854) m toward the final alignment target of (0.026, -0.272, 0.793) m. This calls for a forward Y change of +0.039 m and a downward Z change of -0.061 m. I’ll use 3 control steps; I expect this alignment to center the case near image row 330. The left arm can continue toward the same clear-space target during those steps.

The watch case appears at pixel (275, 385), with the band-loop center at (210, 380). The case is on the right side of the band but 45 pixels left of the gripper’s image center at x = 320. The right link6 has world x = 0.027 m, and my previous case estimate of x = 0.026 m would have put it near pixel 320. Could slight camera roll explain the discrepancy, or is the case closer to world x = 0.007 m? My X estimate appears to be off. With optical X aligned with relative world X, the case seems about 0.02 m left of link6. Assuming camera depth around 0.15 m, dx = (275 - 320) / 397 × 0.15 = -0.017 m, giving an updated case X estimate of 0.027 - 0.017 = 0.010 m. The earlier estimate near x = 0.024 m may have been too large. I’ll shift the right link6 left by 0.017 m to x = 0.010 m, centering on the case rather than the farther-left band loop. The case is at image row 385, below the intended contact row of 330, so I still need to advance and lower the gripper. The measured right link6 position is (0.027, -0.294, 0.829) m. Using the revised case estimate (0.010, -0.132, 0.793) m gives local X = 0.162 m and local Z = -0.036 m. The camera-coordinate estimates are y = -0.081 + 0.031 + 0.087 = 0.037 m and z = 0.140 + 0.018 - 0.048 = 0.110 m, predicting image row 374, which is close to the observation. To put the case at local X = 0.14 m and local Z = 0, the right link6 target should be (0.010, -0.272, 0.793) m. This retains the planned forward-and-down alignment while correcting the previous target’s x = 0.026 m. I’ll use 2 control steps with the right gripper open while the left continues moving into clear space, then close after alignment. The estimated open width is 0.08 m; centering the case should help keep the fingertips clear of the band.

The watch case now appears at approximately (290, 390) pixels, with its top near image row 330. Is it still below the finger contact region? The inner fingertips may be near row 330, but perhaps the pads should align with the case center at row 390. My camera calculation placed a contact point 0.14 m along local +X at row 330, although the pads may extend back toward 0.10 m along that axis. In the right wrist view, the open black finger on the left starts near (50, 260) pixels and extends down toward (125, 480). Its inner fingertip’s leading edge may be near (115, 370), while the farthest forward portion may be near image row 300. The case at row 390 appears below the fingertip, but it may still lie between the pads over the depth region projecting to rows 330–480. A contact distance of 0.10 m along local +X projects to row 616, which is too low; 0.14 m projects to row 330, and 0.1576 m to row 275. The case center at row 390 may correspond to about 0.13 m along local +X with some vertical offset. At the final link6 height of z = 0.793 m, I expect the case to have local Z = 0 and local X = 0.14 m, projecting to row 330. Moving forward and down should therefore shift its image position upward from row 390 toward row 330. The measured right link6 position is (0.020, -0.284, 0.813) m, still short of the target (0.010, -0.272, 0.793) m. I’ll continue toward that target for another 2 control steps with the fingers open. I considered continuing the left arm toward its clearance target, but its current position of (-0.346, -0.182, 1.046) m and approximately downward, world-Y closing orientation look safe to hold. I’ll keep the left arm at its measured pose and move only the right arm.

The watch case now appears at pixel (320, 365), centered horizontally between the open right finger pads and near the contact region at image rows 330–365. I’ll close the right gripper to pinch the rigid case’s sides along world X. I’ll use 3 control steps, holding the right arm’s position steady and keeping the left arm clear.

After 3 control steps, the right gripper’s opening command is 0.329, and the fingers still appear open by about 0.03. The watch case is visible between the tips near pixel (320, 370), though I wonder whether the left pad is nearer the buckle than the case. I estimate the left finger’s inner edge at (230, 280) pixels and the right finger’s at (400, 280), with the case near (320, 360). The fingers taper toward their tips. Closure is still progressing. I’ll maintain the close command with both arm poses held steady for another 2 control steps to establish full contact before attempting the lift.

The watch case is now between the right fingers at the bottom center of the wrist view, with the pads around the case and band. The opening command is 0.045 rather than 0, which looks like good contact. I’ll make a vertical test lift to a link6 height of 0.837 m, an increase of 0.04 m, while keeping the gripper’s horizontal orientation steady. Will the watch appear to move upward or forward in the high-camera view? I’ll use 3 control steps and hold the left arm stationary.

The watch moved in the high-camera view from approximately (317, 245) to (315, 236) pixels, an upward shift of 9 pixels during the measured 0.03 m lift. The case appears vertical behind the gripper near (312, 238) pixels and remains between the closed fingers at the bottom center of the wrist view. I attribute the opening command of 0 to the thin case, but the high-camera motion confirms the grasp. The horizontal grasp worked, so I’ll maintain that orientation for transport to the red basket. The right link6 is currently at (0.012, -0.274, 0.827) m. Assuming the case is 0.14 m along local +X, I estimate its position after the lift as (0.012, -0.134, 0.827) m, with the band bottom perhaps at z = 0.78 m, above the table. I could first lift link6 to z = 0.93 m, putting the band bottom around z = 0.88 m to clear the basket rim. For placement, I want the case center inside the red basket at (0.30, 0.08, 0.90) m, above the floor. With the horizontal fingers’ local +X pointing along world +Y, the corresponding link6 target is (0.30, -0.06, 0.90) m with the initial orientation. This is farther forward at y = -0.06 m and lower at z = 0.90 m than the initial pose, and it seems likely to be reachable. I estimate the band bottom as 0.90 - 0.04 = 0.86 m, above the rim at z = 0.84 m. I can release the watch there to drop onto the floor. One staged route is to lift at the current X and Y coordinates to z = 0.93 m, keeping link6 y = -0.274 m and the case near y = -0.134 m. I could then move to (0.18, -0.15, 0.95) m, an estimated distance of 0.214 m, followed by (0.30, -0.06, 0.90) m, an estimated distance of 0.15 m. At the intermediate pose, I estimate the case at (0.18, -0.01, 0.95) m and the band bottom at z = 0.91 m, above the blue and red baskets’ front rims. The route passes near the blue basket’s front, but the raised watch should have clearance. The left arm remains clear at x = -0.346 m. I can combine the initial lift and transport into a direct target of (0.18, -0.15, 0.95) m. Its displacement from the measured right pose is (0.168, 0.124, 0.123) m, with a distance of about 0.242 m, below the 0.25 m command limit. The orientation remains the initial horizontal orientation, and the object would rise 0.123 m. The precheck may pass; I’ll use 8 control steps. I also considered moving the left arm toward its episode-start pose, approximately (-0.30, -0.352, 0.9215) m, to prepare for reset. It is currently at (-0.346, -0.182, 1.046) m with the downward, world-Y closing orientation. Returning to the initial orientation requires about 2.094 rad and therefore gradual rotation. With roughly 500 steps available, I could move it to (-0.35, -0.30, 1.02) m, an estimated distance of 0.12 m, using an intermediate quaternion [0.812, 0, 0.408, 0.408] in wxyz order at interpolation fraction 0.5. That rotation would be 1.047 rad, above the 1 rad limit; fraction 0.35 would give about 0.73 rad. I’ll instead hold the left arm at its current clear pose while transporting the watch and prepare the reset clearance afterward.

The watch has dropped during transport. In the high-camera view, it is back on the table near pixel (315, 249), close to its original position, and the right wrist view shows no case between the fingers. The right opening command is 0. The grasp may not have been secure despite the test lift; perhaps the fingers briefly held the band and then lost it. I also wonder whether the opening command of 0 in obs_000597 already indicated a missed grasp, with the apparent upward motion caused by dragging rather than a secure pinch. I need actual contact between the object and the pads. I’ll switch from the thin case to the thicker band loop, grasping across its outer sides and aiming for an opening command around 0.2–0.4. There are 495 control steps remaining. The watch’s approximate table position is x = 0.02 m, y = -0.13 m. The right link6 is at (0.101, -0.211, 0.888) m with the initial horizontal orientation. It is still commanded closed, so I need to open it. In the earlier horizontal view, the band extended across image x coordinates 160–350 pixels, with the case on the right. I estimate the whole loop’s width at about 0.06 m, compared with an open finger gap of about 0.08 m. Closing on its outer sides with a gap around 0.04 m might give an opening command of about 0.4. The loop center may be near (-0.005, -0.12, 0.79) m. I’m unsure about the precise Y alignment, but using a contact point at ring-center y = -0.12 m and z = 0.785 m suggests a horizontal link6 target of (-0.005, -0.26, 0.785) m with the initial orientation. The pads would close along world X across the loop. The earlier top-down band grasp on the right-side watch had an opening command of 0.079 but slipped during rotation; a horizontal grasp across the loop may provide broader side contact. I should localize the loop center before committing to that grasp. The watch is not visible in the current right wrist view, perhaps because it dropped behind the camera and below the image boundary. I could approach an approximate grasp pose at (-0.005, -0.27, 0.80) m with the fingers open, but I prefer to restore the horizontal view first. I’ll open the right gripper and move it back to (0.026, -0.32, 0.85) m with the initial orientation. I estimate that move from the current pose as 0.151 m. The left arm will remain clear and stationary. I’ll use 5 control steps, then inspect the view to align a broader band grasp.

The watch is not visible at the bottom of the wrist view, and the right arm still needs to move farther back and down toward its approach target. I’ll continue toward the same target for 5 control steps.

The band loop is now visible at approximately pixel (230, 400), with the case to its right at (275, 385). I should grasp across the loop’s outer sides rather than the thin case. The gripper’s image center is x = 320 pixels, so I need to move link6 left along world X by approximately (320 - 230) / 397 times the camera depth. Assuming a depth of about 0.16 m gives an offset of 0.036 m. With the current link6 x coordinate at 0.03 m, this initially suggests a loop-center and grasp-target x coordinate of about -0.006 m. I also need to align the loop’s height and forward position so its center reaches the contact row near image y = 330 pixels. My initial loop-center estimate is y ≈ -0.12 m, z ≈ 0.78 m. The current link6 coordinates are y = -0.315 m and z = 0.852 m, giving an estimated local X distance of 0.195 m and local Z offset of -0.072 m. For contact at local X = 0.14 m and local Z = 0, link6 should be at the loop’s y coordinate minus 0.14 m and at the same height as the loop. The image coordinates and known orientation do not determine depth without a height assumption. I’ll assume the watch rests on the table and use a loop-center height of z = 0.775 m, based on an estimated vertical band-loop height of 0.04 m. The case top is estimated at z = 0.793 m. This makes the loop’s local Z offset -0.077 m. Image row 400 gives an optical Y-to-Z ratio of 0.401. If d is the loop’s distance along local X, the camera equations are optical Y = -0.5d + 0.0667 + 0.087 = 0.1537 - 0.5d and optical Z = 0.866d + 0.0385 - 0.048 = 0.866d - 0.0095. Solving 0.1537 - 0.5d = 0.401(0.866d - 0.0095) = 0.3473d - 0.0038 gives 0.1575 = 0.8473d, so d = 0.1859 m. The estimated loop y coordinate is therefore -0.315 + 0.1859 = -0.1291 m. For this horizontal orientation, local Y is opposite relative world X, and optical X is opposite local Y, so optical X equals the relative world X coordinate. Pixel x = 230 gives (230 - 320) / 397 = -0.2267. The estimated camera depth is 0.866 × 0.1859 + 0.0385 - 0.048 = 0.1515 m, giving a world X offset of -0.03435 m. The loop x coordinate is therefore 0.03 - 0.03435 = -0.00435 m. My refined loop-center estimate is approximately (-0.0044, -0.1291, 0.775) m. I’ll use a horizontal band-grasp link6 target of (-0.004, -0.269, 0.775) m. The fingertips and loop center would both be at z = 0.775 m, with the loop bottom estimated at z = 0.75 m. The estimated loop width of 0.06 m should fit within the open pad gap of 0.08 m. Compared with the earlier case-grasp position, this changes x from 0.012 to -0.004 m, y from -0.274 to -0.269 m, and lowers z by 0.022 m to 0.775 m. I expect the loop center to project near image row 330, with the case to its right and slightly above it. Closing across the outer band may give an opening command around 0.2–0.4. I’ll approach in two stages: first target (-0.004, -0.29, 0.81) m, then the final grasp pose (-0.004, -0.269, 0.775) m. From the current position (0.03, -0.315, 0.852) m, the pregrasp move is 0.034 m left along X, 0.025 m forward along Y, and -0.042 m along Z. I’ll use 3 control steps now and consider 2 for the final alignment. At the pregrasp pose, the tips would be at y = -0.1324 m and z = 0.81 m, approximately aligned with the loop’s Y position and 0.035 m above its center. They could touch the top of the band, so I’ll keep the fingers open and inspect before proceeding.

The band loop’s center appears near pixel (265, 390), still left of the gripper’s center but closer than before. The right link6 is currently at (0.013, -0.302, 0.831) m. I’ll move it to the final alignment target of (-0.004, -0.269, 0.775) m. At that target, I expect the loop’s center to align near image x = 320 pixels. I’ll use 3 control steps to complete this alignment.

The band loop’s center appears near pixel (275, 370), and the right gripper has not fully reached its target. I’ll continue toward the link6 target of (-0.004, -0.269, 0.775) m for 2 control steps. Moving link6 left by 0.009 m should shift the loop roughly 30 pixels rightward in the wrist image. The forward-and-down motion should also move it upward toward image row 330. I expect the loop center to end up near pixel (310, 330), though that remains an estimate.

The right link6 height remains at 0.799 m rather than the target of 0.775 m, perhaps because the fingers are touching the table. Its quaternion has changed slightly. I estimate the band loop’s center at pixel (300, 380), the open fingers’ inner edges at x = 130 and 500 pixels near image row 330, and the band’s outer sides at x = 210 and 400 pixels. The loop fits between the fingers. Closing at the current height of 0.799 m may contact the upper half of the loop. Do the pads close across it at image row 330? The band is near row 380, but the pads extend down to row 480, so they should also contact its outer sides lower in the image. I’ll avoid forcing the gripper farther down, since the table appears to limit descent. I’ll close for 3 control steps at the current measured position and quaternion, then inspect the opening command and whether the band is between the pads. If the opening is nonzero and the band appears held, I’ll make a test lift.

After 3 control steps, the right gripper’s opening command is 0.33, and closure is still progressing. I estimate the fingers’ inner edges near image x coordinates 240 and 400 pixels, and the band’s outer sides near x coordinates 220 and 400 pixels. The right finger appears to touch the case, while the left is near the buckle. This looks promising. I’ll maintain closure for 2 more control steps; the opening command may then be about 0.16.

The right opening command has fallen to 0.046 again. Are the fingers pinching the white buckle or case at the center? The band loop appears below or behind them, with the upper white strap between the fingers. It looks as though closing across the loop collapsed it and let the pads slide onto a thin buckle contact, which may not be stable. I should grasp the rigid case with more pad contact. One possibility is to keep the fingers horizontal but change the closing direction from world X to world Y to pinch the case front and back. The case lies on the right side of the band and appears thin along X. Its thickness along Y may be about 0.015 m, though that is still thin. Grasping the thicker folded strap at the bottom of the watch is another possibility, but the curved brown band there may also be only about 0.015 m thick. Perhaps the previous closures to 0 occurred because the object was not between the pads at the actual contact location. If the case were properly positioned, I would expect an opening command around 0.1. I initially interpreted the loop as flexible and collapsing, but the native watch is likely a rigid mesh. The fingers may instead be slipping along its smooth curved surface into the inner gaps. I need opposing contacts on the case’s sides with enough surface area. I estimate the rectangular case dimensions as roughly 0.025 × 0.03 × 0.01 m. Closing across a width of 0.025 m would suggest an opening command around 0.25 rather than 0. My interpretation of the earlier 0 readings is that the case was not between the pads at the contact point, despite how it appeared in the image. The case needs to lie roughly 0.10–0.15 m along link6-local X, with local Y and Z both 0. My estimated center may have had the wrong local X or Z coordinate, causing the pads to close in front of or behind it. I should triangulate its center more precisely using correctly matched camera features, or determine its local coordinates from the wrist image and an assumed surface. Earlier triangulation residuals were large because I may have matched different features. The watch appears stationary on the table near high-camera pixel (315, 247). The right link6 is at (-0.001, -0.277, 0.799) m, with its orientation near the initial one, and it may have closed empty. In the wrist view, I estimate the white rectangular case between the pads at (320, 315) pixels and the brown bottom of the band at (330, 455). A possible high-camera case feature is near (315, 242), but I still need to identify which visible feature is actually the case. Matching several case corners or buckle holes could help despite the head image’s low resolution. I could use the idle left wrist camera as a closer second view. The left arm is at (-0.346, -0.182, 1.046) m with the downward orientation that closes along world Y. Its camera faces the table, but the watch near world x = 0 m, y = -0.13 m may be at the image’s right edge. An observer pose above and left of the watch, such as (-0.15, -0.25, 1.0) m with that same orientation, could provide a clearer view. I would open and move the right gripper slightly away to avoid occlusion, then match case features between the horizontal right wrist view and the left wrist view. Moving the left camera directly above the watch is another option. The left arm might even grasp it more easily and transfer it to the right, but my purpose here would be observation. Another option is to use right wrist views from different orientations while the watch remains stationary. I already have horizontal and top-down views, including obs_000589 and obs_000490, but the watch may have shifted between them during grasp attempts. Those historical views therefore may not represent the same object pose. Fresh views taken sequentially without contact would be more reliable. For that approach, I considered placing the left observer at (-0.12, -0.25, 1.00) m with the downward, world-Y closing orientation and moving the open right gripper to (0.15, -0.30, 0.95) m with its initial orientation. The left could collide with the right’s current pose at (-0.001, -0.277, 0.799) m while moving in, so I would first open and retract the right while holding the left stationary, then move the observer. This might take about 20 control steps. I could also obtain both views using only the right arm. After opening and retracting, I could move it to a top-down observation pose at (0.024, -0.136, 1.02) m, then to a horizontal observation pose at (0.026, -0.32, 0.85) m without contacting the watch. I already have the current horizontal close-up, so I could record its features, open the gripper, lift link6 to z = 1.02 m at its current x and y coordinates, and move above the watch for a top-down view. The current opening command of 0.046 and the watch’s high-camera position near (315, 247) suggest that it is probably still on the table, although it might be held. Comparing obs_000628 with a new top-down view would be valid only if the watch stayed unchanged. If opening moved it, I would need to let it settle before matching features. Perhaps a different grasp would be simpler than gathering more views. I have not tried a top-down grasp of this watch’s rigid case with closure along world X rather than world Y. That could align the pads with the case’s long sides. The horizontal case grasp was intended to put the case at local X = 0.14 m and local Z = 0, but it still slipped, perhaps because its world X estimate was wrong. A precisely centered top-down grasp with local Y along world X might give a nonzero opening. The precheck difficulties with this orientation occurred on the left arm; the right may be able to use it. Using the case estimate (0.024, -0.136, 0.793) m, a proposed right link6 target is (0.024, -0.136, 0.93) m, with finger contact near z = 0.79 m. This would approach from above with the fingers to the case’s left and right, rather than at the band buckle. I could inspect closure and require a visible high-camera lift before transporting it. However, rotating from the initial 90-degree Z orientation to quaternion [0.5, 0.5, 0.5, -0.5] in wxyz order gives a dot product of 0.3535 - 0.3535 = 0 and a whole-orientation distance of π rad, so the rotation would need gradual increments. I could rotate through an intermediate pose in clear space above the watch at (0.024, -0.136, 1.02) m before descending. This might be easier than stereo, but the repeated failures may be due to position rather than orientation, so better localization is still useful. I will use the current observations and calibrated geometry more rigorously before choosing another grasp. A single wrist view might determine the case position if I knew its plane, but its exact height is unknown even though I think it rests upright. Instead, I can evaluate candidate head-to-wrist correspondences for physically plausible heights and small residuals. For the horizontal obs_000628 view, I estimate the white case face center at wrist pixel (320, 315). Possible head-camera features are near (312, 243) and (330, 250). I considered testing candidates over a head-image grid spanning x = 305–338 and y = 235–255 pixels. A correct correspondence should give a residual near 0 and a plausible height. More directly, I can backproject the wrist pixel into a ray and project points along that ray into the high camera. They should trace an epipolar line. Drawing that line on an enlarged head-camera crop will show where the wrist feature’s possible matches lie, so I can inspect its intersection with the visible case instead of guessing correspondences. I can do the same for band features. Selecting the matching high-camera point along the line would then allow triangulation of the feature’s position. I’ll use the current right calibration for wrist pixel (320, 315), sample camera Z depths from 0.05 to 0.5 m, transform those points into the environment frame, and project them into the high camera. The current wrist image appears to show the white rectangle at (320, 315), while the watch is near high-camera pixel (315, 247). I’ll generate an enlarged head-camera crop with the case’s epipolar line and lines for nearby wrist features, then inspect it before trying another grasp.

I’ll inspect the enlarged head-camera crop with the epipolar lines to identify which visible watch feature matches the estimated case point in the wrist view. This should help resolve the uncertain case location before another grasp attempt.

The red, green, and yellow epipolar lines lie near image x coordinates 315–320 pixels, while the cyan line is diagonal. The gripper fingers obscure the watch case in the current head-camera view: the central white strap or case is behind the black fingers, and only the band’s left and right sides are visible. I therefore cannot match the case between the current head and wrist views. The case’s identity was also unclear in earlier unobstructed head-camera images. I’ll use the pre-grasp observation obs_000615, where the gripper appears near pixel (340, 270) and does not obscure the watch near (315, 245). The watch is also visible in that observation’s horizontal right wrist view. I’ll use the estimated wrist-image case center at (275, 385) pixels and band center at (230, 400) pixels to generate epipolar lines on an enlarged head-camera crop and help identify the matching features.

I’ll inspect the enlarged pre-grasp head-camera crop with the epipolar lines to identify which watch features correspond to the estimated case and band points in the wrist view. This should help resolve the uncertain case location without the current gripper occlusion.

The black gripper tip still obscures the lower-left part of the band in the head-camera view, but the case on the right is visible. The red epipolar line for the wrist-image case center at (275, 385) pixels passes through the vertical white feature on the right near head-camera pixel (331, 248). This confirms my identification of that feature as the case. I estimate the intersection near (331, 247) pixels. I’ll triangulate using the obs_000615 wrist point (275, 385) and head-camera point (331, 248). I expect a small residual. I’ll calculate the precise position and its local coordinates relative to the end effector.

The head-camera horizontal residual of -3.86 pixels suggests that the actual horizontal coordinate may be around 334.5 pixels, although the red epipolar line may intersect the case center near (334, 250). For the wrist-camera point (275, 385), varying the depth traces this red line in the head-camera image. I should choose a matching point on it; the vertical white case’s center may be around (333, 249). In the enlarged crop, I estimate that the red line passes through the right-side white case from (329, 243) to (333, 253) in head-camera coordinates. The case center might still be near (331, 248), but does the roughly 3.8-pixel residual mean the line at that row is actually at x = 334.9 rather than 331? I am unsure of the horizontal coordinate where the line overlays the case’s right edge. The center could instead be near (334, 250). I’ll test triangulation with nearby head-camera candidates, including (335, 250), while retaining the wrist-camera point (275, 385).

The residual’s sign seems odd: increasing the head-camera x coordinate makes the horizontal residual more negative. Does that mean the least-squares solution predicts a head-camera x coordinate greater than the input? Could the head and wrist rays be nearly diverging, or could the optimizer be stuck in a local minimum? It starts from the environment-frame position [0, -0.12, 0.79] m. The perspective projection is nonlinear, but triangulation should have a unique solution. The roughly 4-pixel residual may mean the rays do not intersect exactly because of the selected pixel correspondences. Moving the head-camera point along the epipolar line should reduce the residual, but perhaps the red line’s slope means I need to decrease x rather than increase it. I’ll check a head-camera candidate at (325, 245) pixels.

The head-camera candidate at (325, 242) pixels gave a horizontal reprojection residual of -2.26 pixels. The candidate at (322, 240) pixels might give a residual near zero, so I’ll test it and nearby candidates.

The previous right-arm orientation target exceeded the 1 rad limit, so no motion occurred. The current slight roll may have contributed; I estimate the distance to the quaternion beginning with 0.806 at about 1.08 rad. I could calculate a smaller rotation using an interpolation fraction of 0.25 from the initial orientation toward the downward orientation that closes along world Y, or reuse [0.795489, 0, 0.238672, 0.556985] in wxyz order. Was that quaternion obtained by normalized linear interpolation? The earlier spherical interpolation from the 90-degree Z orientation to the 90-degree Y orientation at fraction 0.3 gave [0.798654, 0, 0.252311, 0.546343], with a rotation distance of 0.628 rad. I’ll use that quaternion. It is also the fraction-0.7 quaternion along the reverse path from top-down to the initial orientation. My estimated dot product with the current quaternion is 0.563 + 0.004 + 0.387 = 0.954, giving an orientation distance of about 0.613 rad, within the limit. I’ll keep the right position target at (0.014, -0.20, 0.95) m and use 6 control steps to open and lift the right gripper with this smaller rotation, while holding the left arm stationary.

The right arm is lifting very slowly because of its orientation at this low pose, but I expect it to reach the target link6 height of 0.95 m eventually. I’ll continue toward the same target for another 8 control steps.

After 14 control steps, the right link6 is only at z = 0.847 m, still below the target height of 0.95 m. The rotation and low joint configuration seem to be slowing the motion. I could continue for another 8 steps. Could I target the downward orientation that closes along world Y now? The current quaternion is [0.764, 0.01, 0.131, 0.632] in wxyz order. I estimate its dot product with that goal as 0.54 + 0.093 = 0.633, giving an orientation distance of 2.254 rad, above the 1 rad limit. I should keep the intermediate quaternion [0.798654, 0, 0.252311, 0.546343], whose remaining orientation difference I estimate at about 0.65 rad. I’ll continue toward the same right position target, (0.014, -0.20, 0.95) m, for another 10 control steps while holding the left arm stationary and keeping both grippers open.

The watch is out of the wrist camera’s view, but the motion path is clear. I’ll continue the right arm’s lift and rotation toward the same overhead pose for 8 control steps.

The right wrist is nearly at its intermediate orientation. I considered targeting the final downward orientation that closes along world Y, [0.707, 0, 0.707, 0] in wxyz order. Using the current quaternion, the scalar-component product is 0.796 × 0.707 ≈ 0.563, the Y-component product is 0.242 × 0.707 ≈ 0.171, and the Z-component contribution is 0.554 × 0 = 0. Their sum is approximately 0.734, giving an estimated orientation distance of 1.495 rad, above the 1 rad command limit. I could use another intermediate rotation of 0.8 rad toward that goal, with a tentative quaternion around [0.77, 0.13, 0.61, 0.39]. Instead, I’ll first finish reaching the existing intermediate quaternion, [0.798654, 0, 0.252311, 0.546343]. The right link6 has also not reached its position target of (0.014, -0.20, 0.95) m. I considered continuing for 5 control steps, but I’ll use 6 before progressing toward the final downward orientation.

I’ll rotate the right gripper toward the top-down orientation that closes along world Y, using an intermediate rotation of 0.8 rad. Its current quaternion is [0.799, 0, 0.252, 0.546] in wxyz order. My estimated dot product with the desired orientation is 0.565 + 0.178 = 0.743, giving an orientation distance of 1.466 rad. This calls for an interpolation fraction of about 0.55. My tentative intermediate quaternion is [0.772, 0.143, 0.603, 0.374] in wxyz order. Rather than use that approximation, I’ll calculate the quaternion with spherical interpolation in Python.

The calculated intermediate quaternion is approximately [0.802, 0, 0.535, 0.267] in wxyz order, giving a tilted orientation before the final downward orientation that closes along world Y. I’ll move the right link6 from (0.014, -0.20, 0.949) m to (0.014, -0.135, 1.02) m above the watch. I estimate the position distance as 0.096 m and the intermediate rotation as 0.8 rad, and I judge this motion safe. I’ll use 6 control steps.

I’ll continue toward the same overhead position and intermediate orientation targets for another 6 control steps.

I’ll continue toward the same overhead approach position and intermediate wrist orientation for another 6 control steps.

I’ll continue toward the intermediate target for 5 control steps before progressing to the final downward orientation that closes along world Y. Could I advance toward that final orientation now through another intermediate rotation? The right arm’s measured quaternion is [0.817, 0.001, 0.433, 0.381], and the current intermediate target is approximately [0.802, 0, 0.535, 0.267], both in wxyz order. I estimate their orientation difference as 0.295 rad, so I’ll first finish reaching the existing intermediate target with a 5-step action.

The watch is visible near the bottom of the right wrist view, with its case at approximately pixel (459, 417) and its band center at (428, 438). The right gripper is currently tilted. My estimated quaternion dot product with the final top-down orientation that closes along world Y is 0.571 + 0.360 = 0.931, giving an orientation distance of 0.745 rad, below the 1 rad command limit. I’ll target the right link6 at (0.014, -0.135, 1.02) m with that top-down orientation and use 5 control steps.

I’ll continue rotating the right gripper toward the top-down orientation that closes along world Y for another 5 control steps.

I’ll continue rotating the right gripper toward the top-down orientation that closes along world Y for another 4 control steps.

In the top-down right wrist view, I estimate the watch’s case face at pixel (300, 155) and the ring center at (295, 200), with the case toward the top-right of the ring. The right link6 is at (0.014, -0.135, 1.02) m, with the fingers pointing downward and closing along world Y. What is the case’s actual world X coordinate? Its image row of 155 pixels could help estimate that, but its Z coordinate is still unknown; world X may be around 0.02 m. At this orientation, optical X points opposite world Y. The case’s horizontal pixel coordinate of 300 gives an estimated relative Y offset of (320 - 300) / 397 times the depth, approximately +0.007 m. Adding that to link6’s Y coordinate gives an estimated case Y coordinate of -0.128 m. I’ll move the right link6 +0.007 m along world Y to center the case horizontally. I’ll lower the right link6 toward z = 0.90 m in stages: first to 0.96 m for 4 control steps, then to 0.92 m for 4 steps, and then to 0.90 m for 3 steps. At each stage, I’ll inspect the case and align its horizontal image coordinate with pixel 320. For the immediate action, I’ll target (0.014, -0.128, 0.96) m with the right gripper open, hold the left arm stationary, and use 4 control steps.

The watch case now appears centered near pixel (316, 195), with the ring center near (305, 240). The right link6 is at (0.013, -0.128, 0.974) m. Is the case face upright? It appears square and has visible thickness, positioned at the top of the ring, but its orientation remains uncertain. I’ll continue descending with the right gripper open, targeting (0.014, -0.128, 0.92) m for 4 control steps. After that, I plan to lower it toward z = 0.90 m.

The watch case now appears centered at pixel (320, 290). I estimate the open fingertips’ inner edges at x = 115 and 525 pixels, spanning image rows 280–450. The case appears about 90 pixels wide. The pads might contact its sides near x = 280 and 365 pixels; another estimate puts the case edges at x = 275 and 360 pixels, with its center at x = 320. At image row 300, I estimate the fingers’ inner edges near x = 170 and 470 pixels, so they are still open around it. Horizontal closure there appears aligned with the case center, which looks promising, although the exact contact remains uncertain. I could lower the right link6 by 0.01 m from its measured height of 0.927 m to 0.917 m to bring the case center toward image row 330; the pad center may be near row 350. In obs_000490, the case center appeared near row 310 at a link6 height of 0.94 m, but closure missed it. Here it appears near row 290 at 0.927 m. Lowering should move the case downward in the image, although the actual position and orientation differ between those observations. To bring the case toward row 330, I’m considering lowering by 0.015 m to 0.912 m. I’ll command a target height of 0.905 m for 3 control steps, expecting the measured height may only reach about 0.912 m. The fingertips may contact the table, but I judge this lower stage acceptable. I’ll keep the fingers open during the descent and close afterward.

The right link6 height is 0.924 m and has barely decreased. Its quaternion has changed slightly, possibly because of contact. The watch case has moved rightward and downward in the wrist view to approximately pixel (330, 300). The fingers seem to be touching the table, limiting descent at this height. I estimate the fingertips at z = 0.766 m and the table perhaps at z = 0.76 m, so I cannot lower farther. I’ll close the right gripper at the current pose for 3 control steps. Will the pads contact the case securely? That remains to be checked.

The watch case appears between the closing pads at pixel (365, 310), with the fingers near image x coordinates 250 and 480 pixels. The case is right of the closing center at x = 320 pixels. I should have centered it, but I expect contact during closure to push it. The right gripper’s opening command is 0.377, and closure is still progressing. I’ll maintain closure in place for another 2 control steps before lifting.

The right gripper’s opening command is 0.286, which is nonzero. The right finger visibly contacts the case’s right side, while the left finger is near the left strap. I estimate the case’s left side at image x = 330 pixels; could the left finger be at x = 320 pixels? It may be pinching the case. I think the reported opening of 0.286 likely reflects the actual gap. I considered closing for one more control step before testing the grasp, but I’ll proceed directly with a 0.04 m vertical test lift to a link6 height of 0.964 m, keeping the gripper closed. I’ll use 3 control steps. If the watch moves in the high-camera view and the opening remains nonzero, I’ll take that as evidence of a successful grasp.

The right opening command is 0 again, and the watch appears at high-camera pixel (306, 250), having moved left and down rather than lifting. The grasp is not secure. In the wrist view, the case is to the right of the closed fingers, so I think it shifted aside during closure and the pads closed empty to its left. The left finger appears to have contacted the band or strap first, rotating the watch and moving the case rightward. I need to center the gripper on the case while avoiding interference from the band. In obs_000720, I estimated the case center at image x = 330 pixels, slightly right of the closing center. After closure in obs_000725, I estimate it at x = 380 pixels, a rightward shift of 50 pixels. Pre-shifting the gripper toward the case by perhaps 50 pixels might reduce this displacement. I chose world y = -0.128 m based on an earlier case image coordinate of x = 300 pixels, but the case may have drifted during descent because an open finger pushed it. Its exact offset along world Y remains uncertain. A translation alone may not resolve the interference. In the top-down image, the case center is near x = 330 pixels, the band loop spans x = 180–420 pixels, and the open fingers’ inner edges are at x = 130 and 510 pixels, enclosing the entire band. I considered shifting the gripper rightward in the image by 80 pixels to a closing center of x = 400 pixels, but that would leave the case left of the center. Translating the gripper changes the relative positions of both the case and band. Rotating the closing direction or approaching from the side seems more promising. I have not tried the top-down orientation that closes along world X for this watch. Rotating the gripper 90 degrees in yaw would present the fingers across the case’s other axis. Relative to the present wrist view, this would change closure to the vertical image direction, where the case is above the ring and the loop below may interfere less. This could isolate the case better. The right link6 is currently at (0.018, -0.13, 0.961) m, with an orientation close to the downward pose that closes along world Y. The proposed world-X closing quaternion is [0.5, 0.5, 0.5, -0.5] in wxyz order. Its orientation distance from the world-Y closing pose is approximately 1.571 rad, so I would need two increments, initially about 0.8 rad. A possible open-gripper pose above the case is (0.014, -0.128, 1.02) m, followed by a descent with the case centered. For the proposed orientation, local Y aligns with world X and local Z with world -Y, while optical X points along world -X. I am still unsure of the optical Y direction and the case’s world-X offset relative to the ring. The case’s position on the right in the high-camera view suggests a world-X offset of about +0.02 m. The loop extends along world Y, so closing along world X may pinch the case’s width with less band interference. The approximately 1.57 rad rotation would take two increments, and 372 control steps remain. I initially considered opening and lifting to z = 1.03 m while rotating about 0.8 rad toward the new orientation, then completing the rotation. However, rotating at low height with the watch beneath the fingers could cause contact. I’ll first open and lift vertically to (0.018, -0.13, 1.05) m while holding the current quaternion [0.699, 0.009, 0.715, 0.008] in wxyz order. I considered 3 steps for this lift, but will use 4. The left arm will remain stationary, and I’ll rotate the right gripper once it is higher.

The watch has moved or rotated during the grasp attempts. I now estimate the case at wrist-image pixel (340, 200), the ring center at (325, 230), and the watch at high-camera pixel (306, 250). I should recompute the case position using the current nearly top-down right link6 pose, (0.02, -0.133, 1.008) m. Assuming the case height is z = 0.79 m gives a distance of 0.218 m along local X. The local Z coordinate corresponds approximately to the unknown world-X offset, dx. Optical X is the negative relative Y coordinate, so wrist-image u = 340, using an estimated camera depth of 0.15 m, gives a relative Y offset of -0.010 m and a case Y coordinate of -0.143 m. The optical vertical coordinate is -0.109 - 0.866dx + 0.087 = -0.022 - 0.866dx, and the depth is 0.189 - 0.5dx - 0.048 = 0.141 - 0.5dx. Image v = 200 gives a ratio of -0.1008, so -0.022 - 0.866dx = -0.0142 + 0.0504dx. Thus, -0.0078 = 0.9164dx, giving dx = -0.0085 m and a case X coordinate of 0.0115 m. The estimated case position, (0.0115, -0.143, 0.79) m, seems reasonable. For a top-down grasp that closes along world X, I’ll use case coordinates x = 0.012 m, y = -0.143 m, and z = 0.79 m. With local X pointing downward, the proposed link6 grasp position is (0.012, -0.143, 0.93) m. Before descending, I should rotate while positioning above the case at (0.012, -0.143, 1.03) m. The current right quaternion is [0.699, 0.009, 0.715, 0.008] in wxyz order, and the desired world-X closing quaternion is [0.5, 0.5, 0.5, -0.5]. My estimated dot product is 0.3495 + 0.0045 + 0.3575 - 0.004 = 0.7075, giving an orientation distance of about 1.571 rad. I’ll calculate an intermediate quaternion with SciPy for a 0.8 rad rotation increment.

I’ll target the right arm at position (0.012, -0.143, 1.05) m with quaternion [0.64683, 0.2803, 0.65533, -0.27127] in wxyz order, lifting it by 0.042 m while rotating toward the perpendicular case grasp. Its current opening command is 0.968, and I’ll keep it commanded open so it opens fully. I’ll use 6 control steps.

I’ll continue toward the right arm’s intermediate perpendicular-grasp orientation for another 6 control steps.

I’ll continue toward the right arm’s intermediate perpendicular-grasp orientation for another 5 control steps.

The right gripper’s current quaternion is near the intermediate target. Its dot product with the final top-down quaternion [0.5, 0.5, 0.5, -0.5] in wxyz order is 0.658 × 0.5 + 0.252 × 0.5 + 0.667 × 0.5 + (-0.242) × (-0.5) = 0.329 + 0.126 + 0.3335 + 0.121 = 0.9095. I estimate the remaining orientation distance as 0.86 rad, below the 1 rad command limit, so I can target the final orientation with the fingers closing along world X. The right-arm precheck at position (0.012, -0.143, 1.05) m might fail as the left arm’s did. The right arm may have similar joint limits, but its different workspace position could allow this pose. I’ll try the final alignment for 5 control steps.

The nominal top-down orientation that closes along world X also failed for the right arm, which I attribute to a joint limit. An alternative is quaternion [-0.5, 0.5, -0.5, -0.5] in wxyz order, with local Y pointing along world -X. It may be reachable through a different rotation path. From the current quaternion [0.658, 0.252, 0.667, -0.242], my dot-product estimate is -0.329 + 0.126 - 0.3335 + 0.121 = -0.4155. Using its absolute value gives an orientation distance of about 2.285 rad, exceeding the 1 rad command limit, so I would need intermediate rotations. Alternatively, the current orientation may already point local X nearly downward and rotate the closing axis enough to avoid the watch band. I tentatively estimate local X as (0.186, 0.037, -0.982) and local Y as (0.85, 0.43, 0.3), though I question whether these estimated axes are perpendicular. Local Y is mostly in the world XY plane and might be suitable for grasping the case along its other axis. I could retain this quaternion and descend at an adjusted position without reaching the exact nominal orientation, as I did for the purple chocolate with the left arm. In the current right wrist view, I estimate the case at pixel (335, 155) and the band center at (345, 190), with the open fingers diagonally positioned at the lower left and right. Another tentative estimate for local Y is (0.77, 0.59, 0.25) in world coordinates. This diagonal closing direction might still contact the band. The alternative quaternion points local Y along world -X, reversing the closing direction and flipping the camera view. I think it is likely reachable through incremental rotation. I’ll calculate an intermediate quaternion for a 0.8 rad rotation toward that alternative and calculate the current local X and Y directions before deciding.

The current local Y axis has world-XY components of approximately (0.655, 0.756), so the closing direction is still diagonal rather than fully perpendicular. The alternative quaternion [-0.5, 0.5, -0.5, -0.5] in wxyz order points local X downward and local Y along world -X, giving the desired grasp axis with the fingers swapped. The nominal orientation failed the right-arm precheck, but this alternative might pass. The calculated path first moves toward [0.703087, -0.026778, 0.709776, 0.03421], which is close to the top-down orientation that closes along world Y, with a small roll. I can then rotate toward the alternative, perhaps using three increments in total. This route seems circuitous, but it may be necessary. Once near the world-Y closing orientation, I could use another 0.8 rad intermediate rotation toward the alternative. I have about 350 control steps remaining. I’ll first command the calculated intermediate quaternion, a 0.8 rad rotation from the current orientation, keeping the right arm at essentially the same position and using 5 control steps.

I’ll continue toward the same right-arm intermediate orientation for another 6 control steps, keeping the left arm stationary and both grippers open.

I’ll continue rotating the right gripper toward the same intermediate orientation for another 4 control steps.

The right gripper’s current quaternion, [0.703, 0.024, 0.710, -0.016] in wxyz order, is close to the top-down orientation that closes along world Y, with a small roll. The alternative top-down quaternion is [-0.5, 0.5, -0.5, -0.5]. My dot-product calculation is -0.3515 + 0.012 - 0.355 + 0.008 = -0.6865. Using its absolute value gives an estimated orientation distance of 1.629 rad, exceeding the 1 rad command limit. I’ll calculate an intermediate quaternion for a 0.8 rad rotation toward the alternative, using an interpolation fraction of approximately 0.49. A tentative halfway quaternion might be approximately [0.03, 0.45, 0.45, -0.77] in wxyz order, but I’ll compute it rather than use that estimate.

I’ll target the right gripper’s quaternion at [0.6569, -0.2546, 0.6608, 0.2590] in wxyz order, keeping its position unchanged at (0.012, -0.143, 1.05) m. I’ll use 6 control steps for this rotation toward the swapped-finger perpendicular grasp.

I’ll continue rotating the right gripper toward the same intermediate target for another 6 control steps.

I’ll continue rotating the right gripper toward the same intermediate orientation for another 5 control steps.

The right gripper’s current quaternion is close to the intermediate target [0.657, -0.255, 0.661, 0.259] in wxyz order. For the alternative swapped-finger quaternion [-0.5, 0.5, -0.5, -0.5], my dot-product estimate is -0.332 - 0.1275 - 0.334 - 0.12 = -0.9135. Using its absolute value, I estimate the remaining orientation distance as 0.83 rad, below the 1 rad command limit. I’ll target the alternative orientation now for 5 control steps. The kinematic precheck may pass or fail.

The alternative swapped-finger orientation passed the precheck, and the right gripper is rotating toward it. I’ll continue toward the same orientation for another 6 control steps.

I’ll continue rotating the right gripper toward the same alternate perpendicular orientation for another 6 control steps.

The right gripper’s current quaternion is [0.534, -0.462, 0.535, 0.463] in wxyz order. The alternative target, [-0.5, 0.5, -0.5, -0.5], is sign-equivalent to [0.5, -0.5, 0.5, 0.5]. Their dot product is 0.267 + 0.231 + 0.2675 + 0.2315 = 0.997, giving an estimated remaining orientation distance of 0.155 rad. I’ll finish this small rotation with 3 control steps.

The right gripper’s measured quaternion, [0.503, -0.497, 0.503, 0.497] in wxyz order, matches the negative of the alternative target quaternion. This gives the swapped-finger top-down orientation, with local Y pointing along world -X. In the wrist image, I estimate the case at pixel (290, 120) and the band-loop center at (250, 110). The open fingers are at the bottom left and right. Is the camera rotated 180 degrees? Closure still appears horizontal in the image, with the case to the right of the band. I want to align the case with the grasp center at pixel (320, 330) after descending. The current right link6 position is (0.012, -0.143, 1.05) m, and my previous case estimate was (0.011, -0.143, 0.79) m. Its observed position at (290, 120) pixels suggests an offset. With local Y along world -X, optical X equals world X, so u = 290 indicates that the case is about 0.008 m left of link6. I’ll use a link6 X target of 0.004 m. For this alternative orientation, local X points downward, local Y along world -X, and local Z along world +Y. Optical Y is therefore -0.5d - 0.866r + 0.087, where d is the distance along local X and r is the relative world-Y offset. Assuming the case is at z = 0.79 m gives d = 0.26 m. Optical Z is approximately 0.225 - 0.5r - 0.048 = 0.177 - 0.5r, and optical Y is -0.13 - 0.866r + 0.087 = -0.043 - 0.866r. At image row 120, the ratio (120 - 240) / 397 is -0.302. Solving -0.043 - 0.866r = -0.302(0.177 - 0.5r) = -0.0535 + 0.151r gives 0.0105 = 1.017r, so r = 0.0103 m. The estimated case Y coordinate is then -0.143 + 0.0103 = -0.1327 m. I’ll use the revised case estimate (0.004, -0.133, 0.79) m. I could center link6 at (0.004, -0.133, 1.05) m and then descend to z = 0.92 m. Is the case sufficiently isolated from the band? The band center is at image x = 250 pixels and the case at x = 290; I expect the correction to shift both rightward by 40 pixels, putting the band center at 290 and the case at 330. I estimate the open fingers’ inner edges near x = 90 and 550 pixels, so the entire band would still be between them. The left finger might contact the band before the case. I am also unsure whether closing along world X now follows the case’s length; I’ll inspect the alignment as I descend. Another possible inspection target is (0.004, -0.133, 0.93) m. For now, I’ll first target right link6 at (0.004, -0.133, 0.96) m with the exact alternative quaternion [-0.5, 0.5, -0.5, -0.5] in wxyz order. I’ll keep both grippers open, hold the left arm stationary, and use 4 control steps.

The watch case now appears at pixel (300, 170), and the ring center is at (250, 150). The right link6 has measured X and Y coordinates of 0.005 m and -0.136 m. It has not fully reached the previous target of (0.004, -0.133, 0.96) m, but the alignment looks acceptable. I’ll continue descending toward (0.004, -0.133, 0.92) m for 4 control steps. I expect the case center to reach image x = 320 pixels at contact, but its vertical image coordinate remains uncertain.

The watch case appears at pixel (300, 235) in the right wrist view, and the ring center is near (240, 210). At a link6 height of 0.92 m, I expect the case to appear near image x = 320 pixels; its image y coordinate might be around 350 pixels. That looks suitable. I’ll descend farther to a link6 target of (0.004, -0.133, 0.915) m over 3 control steps.

The watch has moved toward the bottom edge of the wrist view, and its high-camera position has shifted from approximately (310, 250) to (326, 305) pixels. The fingers seem to have pushed it forward during the descent or subsequent lift. Perhaps descending to a measured link6 height of 0.925 m with the alternative orientation contacted the watch and dragged it toward the robot, along negative world Y. The rotated fingers’ swept path may also have hooked the band. This apparent contact and displacement could explain the repeated grasp failures. I need to reacquire the watch’s position before another approach. I should center the open gripper above it and descend only after alignment, avoiding contact between the open fingers and the band. The watch may now be near world y = -0.25 m. Only its bottom edge is visible in the right wrist view, so moving back could provide a better view. The measured right link6 position is (0.003, -0.132, 0.939) m, above the blue basket’s front area. I’ll use the high-camera calibration to estimate the watch’s new XY position from its pixel location near (326, 305). Assuming z = 0.79 m, I tentatively estimate x ≈ 0.005 m and y ≈ -0.29 m, but I need to calculate the inverse projection to check this.

I now estimate the watch’s Y coordinate at -0.249 m, near the transfer point. The right link6 is at y = -0.132 m, which I describe as behind it, with a +0.117 m Y offset. I am still unsure how the camera is oriented with the alternative perpendicular grasp. The watch appears at the bottom of the wrist view because it is behind the gripper along negative Y. To reacquire it, I could move the right link6 to (0.01, -0.249, 1.05) m while retaining the alternative quaternion. This changes Y by 0.117 m from the current y = -0.132 m and raises Z by 0.111 m; I judge the motion safe. It should center the open gripper above the watch’s new position. I can then descend slowly, taking care not to push it again. With this alternative orientation, the fingers appear to open along world X. I estimate the band’s outer width along X at 0.06 m and the open gap at 0.08 m, so there should be clearance if the gripper is centered. I think the earlier pushing resulted from incorrect Y alignment causing the fingers to hit the band, rather than from the orientation itself. The overhead localization now seems accurate enough. I’ll use the final right target (0.011, -0.249, 1.05) m with the alternative quaternion [-0.5, 0.5, -0.5, -0.5] in wxyz order for 6 control steps.

The watch is now visible near the bottom center of the right wrist image. Its orientation has changed from being pushed: I estimate the case at pixel (365, 405) and the band-loop center at (360, 420). The face looks square, flat, and angled. The measured right link6 position is (0.008, -0.205, 1.008) m, while the watch’s newly estimated center has y = -0.249 m, placing it behind the gripper. Continuing toward the target (0.011, -0.249, 1.05) m will move the gripper back and up. This may bring the watch toward the image center, or perhaps toward the top. I’ll continue toward that overhead target for 6 control steps.

I estimate the watch case at pixel (358, 293) and the band-loop center at (357, 315) in the right wrist view. The right link6 is at (0.011, -0.249, 1.05) m with the alternative perpendicular orientation. The case appears above the band at image x = 358 pixels. Assuming the case height is z = 0.79 m gives a distance of 0.26 m along local X. With this orientation, local Z corresponds to world Y, and optical X corresponds to the relative world-X coordinate. From image u = 358, I estimate the case’s world X coordinate as 0.011 + 0.01 = 0.021 m, rather than 0.011 m. Let r be the case’s world-Y offset from link6. The optical vertical coordinate is -0.13 - 0.866r + 0.087 = -0.043 - 0.866r, and the camera depth is 0.225 - 0.5r - 0.048 = 0.177 - 0.5r. Image v = 293 gives a ratio of 0.1335. Solving -0.043 - 0.866r = 0.1335(0.177 - 0.5r) = 0.0236 - 0.0668r gives -0.0666 = 0.7992r, so r = -0.0833 m. The estimated case Y coordinate is therefore -0.249 - 0.0833 = -0.3323 m. That puts the watch far forward, near y = -0.332 m. Its high-camera position is now approximately (340, 378) pixels, which seems consistent with a Y coordinate near -0.3 m. It shifted from (326, 305) to (340, 378) during the approach even though the gripper was high. Could it still be falling or rolling after the previous collision? It may instead be continuing to slide under its inertia after being pushed. The estimated movement of 0.083 m over 12 control steps, roughly 0.5 seconds, seems plausible for sliding. I should let the watch stop before approaching again. There are 274 control steps remaining. Both arms are currently clear, with the right above the watch, so I’ll use robot_wait for 20 steps while holding their current poses and gripper states. Then I’ll inspect whether the watch’s high-camera position has stopped changing before localizing the case again.

After the wait, the watch is still at pixel (340, 378) in the high-camera view, matching obs_000826. I now recognize that it was already there in that observation, so it appears stationary. My earlier target of y = -0.249 m was wrong because the watch had slid before then. I’ll localize the case using the current stereo views without moving the robot. I identify its face at pixel (358, 293) in the right wrist view and approximately (340, 378) in the high-camera view, with the white square near (340, 377). I believe these are matching features and expect them to triangulate well. I’ll calculate the position now.

The stereo match now places the watch case at approximately (0.037, -0.3666, 0.7463) m, with small residuals. It slid far forward and is now lying flat. My earlier position estimates were wrong because the watch was moving and I matched the wrong features. The case face is around z = 0.746 m, and the table may be at z = 0.74 m. Should the top-down grasp use a link6 height near z = 0.89 m? With a contact distance of 0.14 m along local +X, the link6 height would be 0.886 m, but the fingertips would reach 0.886 - 0.1576 = 0.7284 m, below the estimated table surface. I should instead contact the case near the fingertip extent of 0.1576 m. A link6 height of 0.904 m would put the tips at approximately z = 0.746 m, level with the case top, where the pads near the tips could pinch its edges. This explains why the previous link6 height of 0.925 m was too high: with the case at z = 0.746 m, it was 0.179 m along the downward finger axis, beyond the maximum extent of 0.1576 m. A suitable grasp height for this flat watch is approximately 0.90–0.905 m. Earlier, I commanded z = 0.905 m, but the measured height remained 0.924 m because of timing or contact, so it did not descend enough. The proposed height of 0.904 m may now be reachable, though the fingertips would be near the table. The right link6 is currently at (0.011, -0.249, 1.05) m with the alternative perpendicular top-down orientation, closing along world X. The square case face is horizontal, so this orientation should suit a pinch across its width. The watch is stationary. I’ll first approach at (0.037, -0.3666, 1.0) m, an estimated distance of 0.143 m, then descend slowly toward z = 0.904 m. Keeping this orientation and matching the case’s X and Y coordinates should center it in the wrist view. At the approach height of 1.0 m, its distance along local X would be 0.254 m, with zero relative local Z offset. The projected camera coordinates would be approximately y = -0.127 + 0.087 = -0.04 m and z = 0.22 - 0.048 = 0.172 m, giving image coordinates near (320, 147) pixels. I’ll move above the localized case at z = 1.0 m for 6 control steps.

The watch case currently appears at pixel (343, 233) in the right wrist view, with the ring center at (345, 260). The watch remains stationary at pixel (340, 378) in the high-camera view. The right link6 is at (0.021, -0.3, 1.03) m, still short of the target (0.037, -0.3666, 1.0) m. I’ll continue toward that target for 6 control steps to finish centering above the case.

The watch case is centered at pixel (320, 117) in the right wrist view, and the ring center is at (315, 165). I’ll descend in stages, first to a link6 height of 0.94 m and then to 0.904 m. The current link6 height is 1.002 m, and the estimated case height is 0.746 m, giving a distance of 0.256 m along local X. My projection estimate gives a camera vertical coordinate of -0.128 + 0.087 = -0.041 m and a depth of 0.221 - 0.048 = 0.173 m, predicting image row 146 rather than the observed row 117. There may be some vertical image offset, but I consider the alignment acceptable. The case is centered at image x = 320 pixels. The band’s current outer width is about 140 pixels, and I expect it to grow to about 230 pixels during descent, still fitting within the roughly 400-pixel open finger gap. This should help avoid pushing the watch. I’ll use 4 control steps toward 0.94 m now, then plan 3 steps toward 0.904 m.

The case appears at pixel (306, 145), slightly left of the closing center. With this alternative orientation, optical X aligns with world X, so I estimate the case’s x coordinate as the right link6 x coordinate minus 0.0035 m. The current link6 x coordinate is 0.037 m, giving a corrected target of 0.0335 m, rounded to 0.034 m. I’ll retain the y target of -0.3666 m; the measured y coordinate of -0.365 m is close. I’m considering descending to z = 0.915 m rather than the earlier 0.94 m stage, which I regard as already passed. At the measured link6 height of 0.959 m, the case center appears at image row 145. At 0.915 m, I estimate it might reach row 270. Would a height of 0.904 m put it near row 300? My earlier projection for a point 0.1576 m along local +X gives row 275, so I expect the case to reach row 275 at that fingertip grasp height, rather than row 330. Grasping near the tips is appropriate for this flat object. The open fingertips appear near pixels (120, 270) and (520, 270), so descending should bring the case down between them. I considered targeting (0.034, -0.3666, 0.904) m for 6 control steps, with the measured height perhaps reaching 0.92 m and then 0.91 m. Instead, I’ll first target z = 0.91 m for 5 steps to avoid going below the table. At that height, I estimate the fingertips at z = 0.7524 m, with the case at z = 0.746 m slightly below them; the pad thickness may still allow contact. A height of 0.904 m may be better for the eventual grasp, with the table estimated at z = 0.74 m, but I’ll use 0.91 m for this first descent.

The watch case now looks large and is centered at pixel (320, 205) in the right wrist view. At the final link6 height of 0.904 m, I expect its center to move to image row 250, near the fingertips at row 275. The case is about 100 pixels wide, and the open pads’ inner edges are near image x coordinates 130 and 520 pixels, so the alignment looks suitable. The right link6’s measured x coordinate is still 0.037 m rather than the previous correction target of 0.034 m, but the case is now centered at image x = 320 pixels, so I’ll hold x at 0.037 m. I’ll target y = -0.3666 m and z = 0.904 m for a final 3-step descent. Its current quaternion, [0.497, -0.493, 0.503, 0.507] in wxyz order, is nearly nominal.

The right link6 did not descend and remains at z = 0.925 m, while its quaternion deviated. This suggests contact or a table-clearance limit again. The case center remains at wrist-image pixel (320, 205), and the watch remains at high-camera pixel (340, 378). Could the fingers already be touching the table? My fingertip-height estimate is 0.925 - 0.1576 = 0.7674 m, with the table perhaps at z = 0.76 m, which seems consistent with contact. However, that conflicts with the stereo estimate of the flat case’s top at z = 0.746 m, below that estimated table height. Perhaps the stereo point represents the case bottom on a table at z = 0.73 m. If the fingertips touch the table at z = 0.767 m, that would instead suggest a table height of 0.767 m, making the case-face estimate impossible. The fingertips may not be exactly vertical because of the quaternion deviation, but local X still points downward. A table height around 0.77 m would still conflict with the case estimate. Could the head and wrist estimates have a systematic offset of about 0.02 m? A partially recessed case does not seem plausible. Perhaps a joint limit is preventing descent rather than table contact. The precheck passed the target at z = 0.904 m, and only 3 control steps were executed, so the motion may simply need more steps. Still, the lack of downward progress and the quaternion change could indicate contact with the watch band. The open fingers’ inner edges appear near image x = 130 and 520 pixels, while the band’s outer edges are near x = 200 and 440 pixels, with no apparent contact in the image. The finger bodies could nevertheless be touching the table. If the table is at z = 0.77 m and the case top was originally at 0.79 m, perhaps the newer stereo estimate of 0.746 m came from a bottom corner at high-camera pixel (340, 378), rather than the visible face top. The arm is currently limited at z = 0.925 m, and the case face at image row 205 might correspond to a distance of about 0.18 m along local X. I can try closing at this measured pose without forcing further descent. The case is large and centered; the pads appear on either side around image row 270. Its center is slightly above the fingertips, but the face is about 100 pixels high and appears to span rows 160–240, with the pads perhaps contacting near row 200. Closing along world X may pinch the upper case while leaving the band outside. I have not yet tried closing with this alternative orientation. I’ll close for 3 control steps and inspect the reported opening afterward. A nonzero opening followed by a verified lift would support a successful grasp.

The right fingers now appear to contact the band’s outer sides near image x = 190 and 450 pixels at y = 300 pixels. The top of the case is near image y = 200 pixels and is not between the pads, so I am closing on the band rather than the case. The reported opening command is 0.479, which looks promising for a broader grasp. The pads may grip the whole band at the thicker red strap sections on its left and right sides. Continued closure may secure those sides while retaining a nonzero opening. Unlike the earlier horizontal grasp that collapsed the band, this alternative top-down orientation closes along world X across the red straps while the loop rests flat and supported. This could be stable. I’ll maintain closure for 2 more control steps and inspect the result.

The right gripper’s opening command has stayed at 0.478, and the fingers are physically blocked by the band’s outer sides. This looks like a strong grasp. I’ll make a small vertical test lift of 0.04 m to a link6 height of 0.965 m, keeping the orientation steady and using 3 control steps. If the band follows the gripper and the opening command stays at 0.478, I’ll consider the grasp successful.

The watch stayed in the same position relative to the wrist camera during the lift, and the opening command remains 0.477. It has disappeared from its table position behind the gripper in the high-camera view, so I consider the broader band grasp successful. I’ll carry it toward the red basket while maintaining the current grasp orientation, then tilt it forward for placement. The alternative top-down quaternion is [-0.5, 0.5, -0.5, -0.5] in wxyz order, with local X pointing downward and local Y along world -X. A top-down link6 placement target at (0.30, 0.08, 1.0) m may be unreachable because of its y = 0.08 m coordinate. Instead, I can tilt the fingers toward world +Y while keeping the closing axis along world X, across the band’s width. Rotating about that closing axis should preserve the grasp. The idealized current rotation has columns X = (0, 0, -1), Y = (-1, 0, 0), and Z = (0, 1, 0). I initially wondered which sign of rotation about world X would tilt the fingers forward. Applying R_x(theta) to local X gives (0, sin(theta), -cos(theta)), so a positive 45-degree rotation gives (0, 0.707, -0.707). Local Y remains along world -X. The new rotation would be R_x(45 degrees) multiplied by the current rotation. Its delta quaternion has w = cos(22.5 degrees) ≈ 0.924 and x = sin(22.5 degrees) ≈ 0.383, with y and z both 0. I could use SciPy to multiply it by [0.5, -0.5, 0.5, 0.5], the sign-equivalent current quaternion. With a grasp contact distance of 0.14 m along local X, the tilted contact offset would be +0.099 m along world Y and -0.099 m along world Z. A desired band-center position of (0.30, 0.08, 0.89) m would therefore suggest a link6 target of (0.30, -0.019, 0.989) m. This resembles the earlier tilted placement poses and seems likely to be reachable. The measured right link6 position is currently (0.041, -0.368, 0.957) m. The actual band contact may be nearer 0.17 m along local X because this grasp is near the fingertips, so I should allow for a contact distance of 0.14–0.17 m. With the forward tilt, that gives a Y offset of roughly 0.10–0.12 m. A link6 Y coordinate of -0.03 m would put the band near y = 0.07–0.09 m, inside the basket. I considered a placement target of (0.30, -0.03, 1.02) m, but the clearance may be insufficient. Using a 0.17 m contact distance, the current band-center height is approximately 0.957 - 0.17 = 0.787 m after the lift, with its bottom near 0.75 m. Tilting will rotate the band from flat to angled, and its bottom may extend about 0.08 m below the contact point. At link6 z = 1.02 m, I estimate the contact height near 0.90 m and the bottom near 0.82 m, below the rim. A higher placement target of (0.30, -0.03, 1.08) m would put the contact near z = 0.96 m and the bottom near 0.88 m, allowing an estimated 0.12 m drop on release. This 45-degree tilted pose may be reachable; the right arm previously reached a tilted pose with a quaternion beginning with 0.812 at z = 1.06 m. Once the watch is over the basket, I could lower link6 to z = 1.0 m if needed before releasing. One staged route is to lift vertically to (0.041, -0.368, 1.08) m with the orientation steady, then move to (0.18, -0.20, 1.10) m. I estimate that second segment as 0.22 m, with the band bottom near z = 0.93 m. I could then rotate forward by 45 degrees while moving to (0.30, -0.03, 1.08) m, an estimated 0.226 m position change and 0.785 rad orientation change. Before opening, I would inspect whether the red basket floor is directly beneath the band. There are 222 control steps remaining, which should be enough for placement and return. The left arm will need to reset later, but I’ll leave it in its current clear pose during transport. I initially considered a 6-step vertical right-arm lift to z = 1.08 m. Combining that lift with a move directly to (0.18, -0.20, 1.10) m would give displacement components (0.139, 0.168, 0.143) m and a distance of approximately 0.261 m, exceeding the 0.25 m command limit. Instead, I’ll target (0.15, -0.23, 1.10) m. Its displacement is (0.109, 0.138, 0.143) m, which I estimate as 0.222 m and within the limit. This combines lifting and moving toward the basket in one 8-step action. I judge the path above the table clear, and I’ll retain the measured quaternion [0.491, -0.485, 0.508, 0.516] in wxyz order to keep the grasp steady rather than changing to the exact alternative quaternion.

The watch remains securely held. I’ll continue toward the same right-arm link6 target of (0.15, -0.23, 1.10) m for another 8 control steps, lifting and carrying it toward the red basket.

I’ll calculate the tilted orientation by applying a positive 45-degree rotation about world X to the right gripper’s current orientation. I’ll normalize its quaternion, [0.491, -0.484, 0.508, 0.516] in wxyz order, convert it to SciPy’s xyzw order, and compose the world-X rotation with it. Then I’ll obtain the new quaternion in wxyz order and the resulting local X and Y directions.

The calculated tilted quaternion is approximately [0.639, -0.259, 0.272, 0.671] in wxyz order. Its local X axis has a slight negative world-X component because of the current orientation deviations, with world-Y and world-Z components of 0.717 and -0.696. I initially considered a right link6 target of (0.30, -0.03, 1.10) m. I estimate the contact offset as +0.10 m along Y and -0.10 m along Z, placing the band center near (0.295, 0.07, 1.0) m and its bottom near z = 0.92 m, safely above the basket. I could lower it after inspecting the placement. However, from the measured position (0.148, -0.234, 1.096) m, I estimate the target distance as about 0.254–0.2544 m, using sqrt(0.152² + 0.204²), slightly beyond the 0.25 m command limit. I also considered (0.29, -0.02, 1.10) m, initially estimating its distance as about 0.259 m, then about 0.257 m using sqrt(0.142² + 0.214²). That is still too far. Instead, I’ll target (0.28, -0.03, 1.10) m, with an estimated distance of 0.243 m using sqrt(0.132² + 0.204²), within the limit. This should place the band center near x = 0.273 m and y = 0.07 m, inside the red basket’s estimated X bounds of 0.18–0.42 m. I’ll use the calculated tilted quaternion, an orientation change of approximately 0.785 rad, execute 8 control steps, and inspect the result.

The watch remains securely held, and the red basket is ahead. I’ll continue toward the right-arm link6 target of (0.28, -0.03, 1.10) m for another 8 control steps.

The right wrist view shows the red basket floor directly behind the held band, with the first watch visible inside. The current right link6 position is (0.219, -0.123, 1.104) m, and its tilted orientation is near the target. Assuming the band center is 0.17 m along local X, with local X approximately (-0.02, 0.71, -0.70), I estimate the band center at (0.216, -0.002, 0.985) m. The red basket’s center is near x = 0.30 m, and its estimated X bounds are 0.18–0.42 m. The band at x = 0.216 m is near the left edge but appears inside. With an estimated width of 0.06 m along X, its left edge is at x = 0.186 m, just inside the basket. Continuing toward the link6 target at x = 0.28 m and y = -0.03 m should center it better and put the band near y = 0.09 m. I’ll continue toward the same target for 8 control steps.

The held watch is directly above the red basket floor, with the first watch below it. The bottom of the held band appears near wrist-image row 350, with the red floor behind it. Should I release now? The right link6 height is 1.099 m. Using an estimated contact distance of 0.17 m and a vertical offset of -0.12 m from the tilt, I estimate the band center at z ≈ 0.98 m and its bottom perhaps at z ≈ 0.90 m. The red rim is estimated at z = 0.84 m, and the drop to the floor at z = 0.76 m would be about 0.14 m. I judge this release safe. The watch is tilted 45 degrees and may land fairly flat on the first watch, where I expect it to remain stable and contained. Does the left red strap at wrist-image pixel (200, 260) lie over the left wall? The visible red floor spans image x coordinates 150–570, so I judge the whole band footprint to be inside. I’ll hold the right arm’s pose and open its gripper, keep the left arm clear, and use 4 control steps. Then I’ll inspect the placement.

The second watch is falling upright into the red basket near the back center, with the first watch below it. I should let it settle and verify that it remains inside. Both grippers report an opening command of 1, so release is complete. I believe all objects are now sorted, but native_success is still false; success may require returning the arms to their initial configurations. Before resetting, I need to retract both arms into clear space. The left link6 is at (-0.346, -0.182, 1.046) m with the downward orientation that closes along world Y, and the right is at (0.275, -0.04, 1.099) m with its tilted orientation above the red basket. I could move the open right gripper back toward (0.30, -0.20, 1.05) m, perhaps retaining its current tilt. I estimate that target distance as 0.163 m and judge the motion safe. The left arm is already clear above the table, but I could prepare it for reset by moving to (-0.35, -0.30, 1.02) m with its current orientation and gripper open, where there are no nearby objects. A robot_reset call allowing 50 control steps might then return both arms to their initial configurations. I considered moving the arms clear before waiting, but the right gripper is currently above the basket without contact and the left is clear. I’ll first use robot_wait for 10 control steps with both arms stationary and open, then inspect whether the watch has settled and remains inside before retracting and resetting.

The second watch is now near the bottom-right of the right wrist view, partially occluded by the right finger but inside the red basket near its right wall. The first watch is near the center-left. In the high-camera view, I initially estimate the second watch at pixel (446, 144) and wonder whether it is behind the front wall; it appears near the back interior around pixel (447, 146). Both watches are contained, and I believe all object-placement goals are achieved. I should now prepare clearance before resetting the arms. The left link6 is currently at (-0.346, -0.182, 1.046) m, with its fingers pointing downward and no nearby objects—the purple bar has been removed and the table is empty. I’ll move it to (-0.30, -0.32, 1.02) m, retaining its current downward orientation that closes along world Y and keeping the gripper open. The right link6 is at (0.275, -0.04, 1.099) m, with its fingers tilted and its gripper open above the red basket. I’ll move it to (0.30, -0.25, 1.05) m while retaining its current tilt. I estimate that move as 0.218 m and judge it safe away from the watch and basket. Moving the open right gripper to y = -0.25 m should provide safer clearance from the red basket during the return. I’ll execute both clearance motions for 8 control steps, then plan a reset allowing 50 steps. From the proposed left clearance pose of (-0.30, -0.32, 1.02) m, the initial position (-0.3, -0.352, 0.9215) m is nearby and the return looks safe. The right return from (0.3, -0.25, 1.05) m to its initial position (0.3, -0.352, 0.9215) m also looks safe.

The right wrist view now clearly shows both watches inside the red basket, so the placements look good. Neither arm has fully reached its clearance target yet. I’ll continue toward the same return-preparation poses for another 8 control steps.

The right arm is still at y = -0.186 m, short of its clearance target at y = -0.25 m. In the high-camera view, the gripper appears over the red basket’s front edge, but it is open and withdrawing. The left arm has reached its target. I’ll continue the right arm’s return-preparation motion for 6 control steps, then reset the arms.

Both arms have enough clearance for the return motion. The left arm is close to its initial pose, while the right arm’s orientation is still significantly different from its initial orientation. I’ll call robot_reset with 50 control steps, which I expect will be enough to return both arms to their initial joint configurations.

The episode has ended with native_success set to true, so I should briefly report the supplied successful outcome and take no further robot actions. The reset feedback also reports reached_home as false: native termination occurred before the arms fully reached home. I considered saying that the arms returned, but that would overstate the feedback. I’ll report that all chocolates, peppers, and watches are in their assigned baskets and that the arm-return sequence was executed, without claiming that both arms reached their exact initial configurations.
