按语言分拣物体任务成功

I need to use visual observations to control the robot and sort the objects. I should read the relevant robot-manipulation skill first. I need to identify all the objects and their counts, including how many watches there are. The yellow object near the left gripper in the initial camera view might be a watch. I’ll inspect the observation data and higher-resolution images with the tools to clarify this.

There are likely six objects to sort: two watches near the center at pixels (251, 256) and (302, 238), a yellow pepper on the left near (174, 284), perhaps a bell pepper, a red pepper on the right near (535, 251), a green car near the center at (345, 270), and a red car at (421, 240). The basket x coordinates may be approximately -0.32 m, 0 m, and 0.32 m for the left, middle, and right baskets, but their y coordinates are still unclear. I should use the camera calibration to map these image locations into world coordinates. The table surface may be at z = 0.75 m. The initial end-effector height is about 0.922 m. If I know the table height, I can reconstruct the objects’ positions on that plane from their image projections. I could try z = 0.75 m or 0.74 m. I also need to understand the gripper orientation. The initial quaternion in wxyz order, [0.707, 0, 0, 0.707], represents a 90° rotation about Z, mapping the fingers’ local +X direction to world +Y. Thus, the fingers initially point horizontally forward. The wrist camera’s optical Z direction is approximately [0, +0.866, -0.5], so it looks forward toward +Y and downward. The end effector is at y = -0.352 m and z = 0.922 m; the camera position might be around y = -0.38 m and z = 0.97 m, which I can check by inverting its extrinsic transform. In the high-camera view, the gripper appears near the objects. For a downward grasp, I need to map local +X to world -Z and keep local Y, the closing direction, horizontal. I can choose the yaw to suit the object. A possible downward quaternion is [0.5, 0.5, -0.5, 0.5], though [0.5, -0.5, 0.5, 0.5] is another candidate. I am not yet sure how these map local X into the world frame, so I will check their rotation matrices with SciPy. Moving from the initial orientation may require a 90° rotation, with an intermediate orientation because each action is limited to 1 rad. I considered inspecting available robot kinematics files, but simulator internals are forbidden; I can use general geometry instead. Could the basket geometry help estimate the table height, perhaps around 0.77 m? The gripper fingers’ bottom may initially be around z = 0.89 m, and the yellow pepper appears partly behind the left gripper. A table height of 0.75 m seems plausible, with a basket floor perhaps at 0.76 m and a rim at 0.89 m, but these are estimates. I will use Python to invert the high-camera geometry and project the object-base pixels onto an assumed z = 0.75 m plane to estimate their world positions.

The quaternion [0.5, -0.5, 0.5, 0.5] in wxyz order maps local X to [0, 0, -1], local Y to [-1, 0, 0], and local Z to [0, 1, 0]. This points the fingers downward and makes them close along world X. The quaternion [0.5, 0.5, -0.5, 0.5] instead maps local X to world +Z, pointing the fingers upward, so I will use [0.5, -0.5, 0.5, 0.5] for a downward grasp. Another possibility is [0, 0.707, 0.707, 0], but I still need to check how it maps local X. It might provide the yaw needed to close along world Y; I can calculate that later. I need to assess the objects’ widths. The watches appear to be circular bracelets lying flat, with an estimated diameter of about 4 cm. A top-down grasp across X might work, perhaps gripping inside the loop, but their shape is still unclear. Are they wristwatch-like rings? The watch near pixel (251, 255) seems to show a band loop and a face. I will crop and enlarge the high-camera image to inspect it more closely.

I’ll view the enlarged crop to clarify the objects’ shapes, especially the watches, so I can choose suitable grasp contact points and finger alignment.

I now see a third watch: the black ring beside the right gripper near pixel (465, 295). Along with the silver watch near pixel x = 251 and the dark watch near pixel x = 302, that makes three watches. The black ring appears to be a watch bracelet with a face, although that detail is still tentative. With the yellow pepper on the left, the red pepper on the right, and the green and red cars, I count seven objects. I need to keep this revised count in mind while sorting. I could have the left arm handle the yellow pepper, the central watches, and perhaps the green car, while the right arm handles the red car, red pepper, and black watch. All watches need to go into the left basket, so the right arm may need to cross the middle to deliver its watch. There are 1100 control steps available. Each action allows at most 15 steps, and the bounded joint increments may produce translations of roughly 0.02 m per step, perhaps 0.1–0.2 m over 15 steps. I will use both arms simultaneously where practical. First I need suitable grasp positions and orientations. The table is very likely at world z = 0.75 m. The current end-effector height is about 0.922 m, with the fingers pointing forward. Their approximately 0.157 m forward extension puts them near y = -0.195 m at roughly the same height. The yellow pepper is estimated near y = -0.192 m and z = 0.79 m; could it be beneath the fingers? It appears adjacent to a finger in the high-camera image. The black watch might be near world x = 0.39 m, but I still need to map its position. I will start by turning toward a top-down pose and moving toward the peppers. The yellow pepper is near world x = -0.30 m, y = -0.19 m, and the red pepper is near x = 0.464 m, y = -0.133 m. The left end effector starts near x = -0.3 m, y = -0.352 m, z = 0.922 m, with the fingers pointing forward. In the downward orientation, the fingers extend 0.1576 m below the end effector along local X. A pepper might be about 0.05 m tall on the table at z = 0.75 m, putting its center around z = 0.775 m. A possible end-effector contact height is 0.775 + 0.13 m, but the actual contact location depends on the finger pads. The tips extend about 0.157 m, and the pad surface length may be about 0.1 m. The downward quaternion makes the fingers close along world X. The red pepper is roughly 0.06 m wide, so an opening of about 0.08 may be sufficient. The relevant upper grasp region might be around z = 0.79 m. If the fingertips are 0.1576 m below the end effector, touching that height would require an end-effector height of 0.9476 m. Rotating downward while staying at the current z = 0.922 m would put the tips near z = 0.764 m, close to the table, with a potential collision even though the current area at y = -0.352 m appears empty. I should raise first or rotate while moving above the objects. A top-down approach at end-effector z = 1.0 m would put the tips near z = 0.842 m, leaving clearance above an object top around z = 0.80 m. A later descent to end-effector z = 0.91 m would put the fingertips near z = 0.752 m, close to the table for contact.

The arms have reached the intermediate poses, with the open fingers angled forward and downward at about 45°. Next I want to rotate them fully downward using the wxyz quaternion [0.5, -0.5, 0.5, 0.5] and align them above the peppers, but I should update the object locations first. In the high-camera view, the yellow pepper now appears centered at pixel (164, 286), compared with (174, 284) initially. It seems to have shifted left by 10 pixels, perhaps because the nearby gripper pushed it during rotation. Its estimated world x position changed from -0.30 m to -0.336 m. The red pepper is now near pixel (528, 253), still at approximately world x = 0.46 m. The black watch remains in place, and the green car appears unaffected. I should map the current object positions using the assumed table height of z = 0.75 m. The yellow pepper’s base may be near pixel (165, 292), while the red pepper’s base is approximately at (529, 260). The wrist views show the peppers from above: the left pepper is near (340, 454), partly at the bottom of the image, and the right pepper is near (438, 303). The left end effector is at (-0.3, -0.251, 1.038) m in its intermediate orientation, with the fingers pointing forward and down. Once the fingers are vertical, the end effector’s x and y coordinates should match those of the intended grasp point. However, the wrist camera’s optical axis does not pass exactly through the fingertips, so I need to determine where that grasp point projects in the wrist image rather than assume it is at the image center. I can calculate the fingertip’s world position as EEF + R[:, 0] × 0.1576 m. When local X points exactly downward, the fingertip has the same world x and y coordinates as the end effector. The wrist camera has a fixed offset relative to the end effector. I should also determine the image projection of the pad midpoint, which might be at local x = 0.13 m. I will use the recorded calibration and end-effector poses to derive the camera’s position and orientation relative to link6 and help verify the object positions. In the left wrist image at observation 25, the pepper is near the bottom at u = 340, v = 455. As I rotate downward and center the gripper above it, might it move toward u = 320, v = 240? That remains uncertain because the camera is angled relative to the gripper. I can infer its optical direction in the link frame from the initial 90° Z orientation and the camera extrinsics. If C = T[:3, :3] maps environment coordinates to optical coordinates, then R_cw = C and R_ec = C.T. With R_el mapping link-local coordinates to the environment frame, the camera rotation relative to the link is R_el.T @ R_ec. I will calculate these relationships now.

The camera is mounted at local position (0.085, 0, 0.051) m. The columns of its local rotation matrix give the camera axes in the link frame, and its optical Z axis is [0.866, 0, -0.5]. It therefore looks forward along local X and downward along local Z, perhaps at a fixed 30° angle. With the chosen fully downward orientation, local X maps to world -Z and local Z maps to world +Y. The camera is consequently 0.085 m below and 0.051 m ahead of the end effector, at (x, y + 0.051, z - 0.085). Its optical axis becomes 0.866 × (-Z) + (-0.5) × (+Y) = [0, -0.5, -0.866], pointing toward -Y and downward. Does this mean it looks backward toward the base? It is ahead of the end effector and looks back and down toward the gripper. The gripper-tip projection stays at approximately u = 320, v = 274.7 for every orientation. A contact-pad point at local distance d = 0.14 m might project near v = 333; I should calculate that. At d = 0.1576 m, v = 274.7; at d = 0.13 m, v might be 405; and at d = 0.1 m, v = 615.8. Are the fingertips closest to the camera? That seems strange, although in the initial image the fingers appear along the sides, extending upward toward image y = 250, with the tips around y = 245. For a top-down grasp with the object at the fingertip center, around world z = 0.78 m, and the end effector at z = 0.93 m with matching x and y, I expect the projection near u = 320, v = 274.7. Thus, an object aligned at the fingertip plane should appear around (320, 275) in the wrist image. How does that projection change when the object is below the fingertip at the same x and y? At a pre-grasp end-effector height of z = 1.0 m and object height z = 0.79 m, I estimate the object is 0.07 m below the tip and might project near v = 235. I should calculate this. As I descend, the object should move toward v = 275 when it reaches the tip height, with horizontal alignment at u = 320. In the left wrist image at observation 25, the object is near (340, 455), away from that target because the gripper is not yet fully downward and its position relative to the object differs. I want a fully downward pre-grasp pose above the shifted objects. I can invert the high-camera geometry and also estimate object centers from the wrist cameras using assumed heights. I am using table z = 0.75 m, with the yellow and red pepper top centers perhaps at z = 0.79 m. The yellow pepper currently appears near u = 342, v = 452 in the left wrist image. With the known camera transform T, I can intersect its viewing ray with z = 0.78 m to estimate its world position. I will calculate positions for candidate heights.

The yellow pepper’s position estimates disagree. From the high camera, I initially estimated x = -0.30 m and now perhaps x = -0.34 m, while the wrist-camera calculation gives x ≈ -0.288 m. Did my estimate from the visible object at high-camera pixel (164, 285) give x = -0.34 m? I will project the wrist-derived world position (-0.289, -0.21, 0.78) m into the high-camera image to check where it should appear.

Is the yellow pepper’s center near high-camera pixel x = 165? Its visible body spans x = 148–181, giving a center of 164.5 at y = 286. The wrist-derived world x = -0.289 m projects to x = 170.6 pixels at z = 0.78 m, within about 6 pixels of that estimate. However, the wrist point I used near (340, 453) may represent the visible upper shoulder rather than the body center. In the left wrist image, the yellow pepper appears to span roughly x = 288–393, centered near x = 340. It extends from about y = 415 into the bottom crop, so its actual center might be near y = 459. The stem appears near (343, 464), while the body center could be around (342, 492), outside the image. I used y = 453 on the upper shoulder, not the center. Should I instead use the high-camera body center near (165, 286)? Taking a possible high-camera center of (164, 285) at world z = 0.79 m gives approximately x = -0.315 m and y = -0.210 m. The yellow pepper may have shifted from its initial x = -0.30 m to about -0.315 m. The wrist estimate of -0.289 m may come from selecting a shoulder point farther to the right. I should localize it again once the gripper is fully downward and the whole pepper is visible. The red pepper’s high-camera center near (530, 252) agrees with world x ≈ 0.44 m. Its body center in the right wrist view, near (438, 307), appears usable and gives x ≈ 0.435 m. I will use an estimated right-arm target at x = 0.436 m, y = -0.139 m, and a tentative left-arm target at x = -0.31 m, y = -0.21 m. A fully downward pre-grasp pose at z = 1.02 m should show the whole objects in the wrist views if centered. For this motion, I can rotate fully downward while moving the left end effector to (-0.31, -0.21, 1.03) m and the right to approximately (0.436, -0.14, 1.03) m. The downward fingertips would be at z ≈ 0.872 m, safely above estimated object tops at z = 0.82 m; I am using 1.03 minus 0.157 m as approximately 0.872 m. The orientation change is about 0.78 rad. Both position targets are within the 0.25 m bound: the left target changes y by +0.041 m, x by -0.01 m, and z by -0.008 m; the right changes x by +0.066 m, y by +0.119 m, and z by +0.003 m, for a distance of about 0.136 m. Perhaps 15 steps would reach the final orientation, but I will use 12 steps.

The yellow pepper’s center appears at wrist-image coordinates (367, 325), with its stem at (367, 327). The red pepper’s center appears at (359, 246). I initially expected an object at the grasp contact point to project near (320, 275) with the gripper fully downward. Neither arm has fully reached that orientation, and their end-effector x and y positions still need adjustment. I should complete the alignment before descending. The watches at the edges of the right wrist image are irrelevant to this adjustment. The yellow pepper is to the right of the left wrist image center. Is the wrist camera’s optical X direction world +X independently of this rotation? Its local camera-right axis is [0, -1, 0]. With the downward quaternion, local Y maps to world -X, so camera-right maps to world +X. Thus, the pepper being to the right indicates that its world x coordinate is greater than the gripper center’s. I can estimate the required shift as the pixel offset times depth divided by focal length. The offset from u = 320 to u = 367 is +47 pixels; with an estimated object depth of 0.23 m, this suggests increasing the end-effector x coordinate by about 0.027 m, making it less negative. The high-camera yellow-pepper center appears near pixel x = 165, and the current end-effector x is -0.31 m. The pepper may indeed be near world x = -0.29 m. A left-arm target around x = -0.282 m might work. I also need to understand the vertical image coordinate before changing y. At contact I expected the fingertip target near v = 275, but during pre-grasp the object is below the fingertip. I should calculate where an object center at z = 0.79 m would project with the end effector fully downward at matching object x and y and z = 1.03 m. I must distinguish the stem from the body and the intended grasp point: the body center appears around (365, 318), rather than the stem around (368, 328). I estimate the center of mass at z = 0.785 m and want to grasp the body’s sides at mid-height. A later end-effector descent to z = 0.925 m might put the fingertips at z = 0.767 m and the pad contact near z = 0.79 m. For a fully downward pre-grasp pose at (object.x, object.y, 1.03) m and an object center at z = 0.785 m, the camera is at (x, y + 0.051, 0.945) m. The vector from camera to object is [0, -0.051, -0.16] m. The camera’s local rotation matrix is [[0, -0.5, 0.866], [-1, 0, 0], [0, -0.866, -0.5]]. I briefly need to check what this matrix maps: R_ec has the camera axes as columns in the environment frame, and R_el.T @ R_ec gives those axes in the link frame. Its optical Z axis is therefore [0.866, 0, -0.5] locally. With the downward orientation, the link axes in the environment frame are X = (0, 0, -1), Y = (-1, 0, 0), and Z = (0, 1, 0). The optical axis becomes (0, -0.5, -0.866), while the camera’s downward Y axis is -0.5 × X - 0.866 × Z = (0, -0.866, +0.433). Using the object vector [0, -0.051, -0.16], I obtain y_camera = (-0.866)(-0.051) + 0.433(-0.16) = 0.0442 - 0.0693 = -0.0251 m, and z_camera = 0.0255 + 0.1386 = 0.1641 m. The projected vertical coordinate is v = 240 + 397(-0.0251)/0.164 = 179.3 pixels. Thus, at end-effector z = 1.03 m, an object center at z = 0.785 m with matching x and y should appear near v = 179, rather than v = 275. The fingertip at z = 0.8724 m projects near v = 275. The object is 0.0874 m below it, yet appears above it in the image because of the camera angle. The red pepper currently appears at v = 246 with end-effector z = 1.024 m, but the orientation is incomplete and y is offset. A centered final pre-grasp should put it near v = 180. At a grasp end-effector height of z = 0.925 m, with object center z = 0.785 m, the camera height would be 0.84 m. The camera-to-object vector would have y = -0.051 m and z = -0.055 m. This gives y_camera = 0.044 - 0.0238 = 0.0204 m and z_camera = 0.0255 + 0.0476 = 0.0731 m, so v = 240 + 110 = 350 pixels. The object center would appear near v = 350 at grasp, while its lower bottom at z = 0.75 m might appear near v = 405. The fingertip at z = 0.7674 m still projects near v = 275. Would an object top above the fingertip appear below v = 275? I am not yet sure, but I should not require the object center to project onto the fingertip. I should align x and y using the downward geometry; the vertical image coordinate depends on the object height and end-effector height. Since the current orientations are still intermediate, I should finish rotating downward at pre-grasp height, then use the resulting pixels to refine localization. For the left arm, an x adjustment of about +0.025 m is plausible. The red pepper’s u = 359 suggests a right-arm x adjustment of about +0.02 m, and its y position still needs adjustment. I could target the left arm at (-0.285, -0.21, 1.03) m and the right at (0.436, -0.139, 1.03) m, both with the downward quaternion [0.5, -0.5, 0.5, 0.5]. Perhaps six steps would complete the orientation.

The grippers are now fully downward. The yellow pepper’s center appears at pixel (301, 174), compared with the expected (320, 179) when its x and y coordinates match the end effector’s. Its horizontal offset is approximately -19 × depth / 397. With an estimated depth of 0.165 m, that gives -0.0079 m, so I should set the left end-effector x coordinate to -0.291 m. The red pepper’s center is at (304, 169), suggesting a similar x correction of about -0.007 m and a right end-effector x target of 0.428 m. The y alignment is probably accurate. The observed vertical coordinates of 174 and 169, compared with the expected 179, could reflect center heights nearer z = 0.79 m than the assumed 0.785 m, or small y offsets. The downward fingers are visible at the lower left and right of the wrist images. As I descend from end-effector z = 1.03 m toward 0.925 m while correcting x, the peppers should move down toward image v = 350 and remain horizontally centered. I should use three control steps per action near the objects. The z motion might be about 0.003 m per step, or roughly 0.01 m over three steps, so several calls may be needed. The earlier 12-step action brought the orientation and position toward their targets with relatively small joint motion. I considered five steps, but the final-approach guidance calls for one to three, so I will use three. An initial z target of 0.94 m would be about 0.09 m away, with perhaps only 0.009 m of descent in three steps. Instead, I can use repeated three-step calls toward z = 0.93 m, moving both arms simultaneously and checking the measured motion each time. I still need to judge the table height and finger contact. Does the pepper body in the high-camera image extend from about image y = 251 at the top to y = 299 at the bottom? The yellow pepper’s top may be at world z = 0.82 m, its base at 0.75 m, and its body center at 0.785 m. At end-effector z = 0.925 m, the fingertips would be at z = 0.7674 m, about 17 mm above the table. The pads may span local x = 0.09–0.15 m, giving a vertical contact region around z = 0.775–0.835 m. Closure along world X through the pepper center looks appropriate for an estimated width of 0.06 m and an open gap of 0.09 m. A grasp height of 0.925 m seems plausible. Alternatively, z = 0.91 m would put the tips at 0.7524 m near the table and the pads around z = 0.77–0.82 m. For a pepper diameter of about 0.065 m, side contact near z = 0.78 m would place the pad contact near the lower half of the fingers at end-effector z = 0.925 m. Might these tasks usually use a grasp height of 0.94 m? I will inspect as I descend. For this action, I will keep both grippers open and use three steps toward z = 0.93 m, with left x = -0.291 m and right x = 0.428 m, leaving their y coordinates unchanged.

The yellow pepper’s center appears to be around u = 304 pixels, though I am uncertain, and the red pepper’s center is near u = 309 pixels. Another x adjustment of perhaps -0.004 m should improve alignment. The grippers descended about 0.034 m over three control steps, so I expect the target height of z = 0.93 m to be reached in nine steps. I will continue for three steps toward the same height, with the left end-effector x target at -0.29 m and the right at 0.429 m.

The yellow pepper appears at wrist-image coordinates (u = 307, v = 265), and the red pepper at (u = 315, v = 260). I will adjust the left end effector’s x position by -0.003 m and the right’s by -0.001 m. The open fingertips seem to be near image y = 270 at the edges. The black inner fingertip edges are at approximately (126, 258) and (514, 258), with the object between them. The finger pads appear near y = 330, at edge positions around x = 100 and x = 540. The object appears larger as the gripper descends, and the alignment looks good. I will continue the open-gripper descent for three control steps.

At the left end-effector height of 0.935 m, the fingertips are at z = 0.7774 m, near the estimated pepper body center at z = 0.78 m. This may be an ideal grasp height. In the wrist image, the yellow pepper spans x = 164–477 pixels, while the fingers’ inner edges are at x = 125 and 517 pixels near the tips at y = 260 pixels, so the open gap appears sufficient. I will command both grippers closed for three control steps while holding their poses. I could make a minimal final descent to z = 0.93 m, lowering the left arm by 0.005 m and the right by 0.001 m. The fingers close along world X, and the bodies appear wider along X, so that closing direction looks appropriate.

The gripper opening commands are around 0.43, so closure is not yet complete, and the peppers are between the fingers. I will make a small test lift toward z = 0.98 m for both arms, roughly 5 cm above their current heights, while keeping the grippers commanded closed. I will use three control steps, which may produce about 0.03 m of upward motion, then check whether the peppers move with the grippers.

Both peppers clearly moved upward during the test lift, and they remain stable relative to the grippers in the wrist views. In the high-camera image, the yellow pepper is near pixel y = 281 rather than its initial table-level y = 286; its bottom may no longer be touching the table. The red pepper is near pixel y = 246 rather than 253. I can proceed toward the middle basket. I estimate the middle basket’s world center at x = 0 m, y = 0.055 m. Its bottom may be at z = 0.765 m and its rim around z = 0.84 m. In the high-camera image, it extends from the top rear near pixel y = 140 to the front bottom near y = 212. The world mapping used a center at y = 0.055 m, z = 0.75 m, but the actual bottom may be at z = 0.765 m; I am still unsure how that affects its projected y coordinate. I initially considered placing the peppers into the basket from an end-effector height of z = 0.98–1.0 m, but I need clearance over the rim. If an object extends 0.15 m below an end effector at z = 0.96 m, it reaches z = 0.81 m, below a possible rim height of 0.83 m. Is the pepper’s current bottom around z = 0.80 m? Using the grasp pose instead, the end effector was at z = 0.933 m and the object bottom at z = 0.75 m, a separation of 0.183 m, with the fingertips around z = 0.775 m. At end-effector z = 0.963 m, the bottom would therefore be around z = 0.78 m, still too low. To clear a rim around z = 0.82 m, I need an end-effector height above 1.01 m. I will raise toward z = 1.08 m while moving inward. I could place the peppers at slight offsets of x = ±0.06 m, y = 0.055 m to avoid collisions. The basket’s inner width may be about 0.24 m. For comparison, the left basket is centered at x = -0.32 m and spans roughly -0.44 to -0.20 m; the middle basket’s inner x extent may be ±0.11 m, with depth from y = -0.03 to 0.14 m. Possible placement points are yellow at (-0.055, 0.04) m and red at (0.055, 0.05) m. The arms currently start near x = -0.29 m and 0.43 m. A direct inward move at z = 1.08 m needs an intermediate pose: my left-arm target-distance estimate is sqrt(0.236² + 0.25²) = 0.344 m, exceeding the 0.25 m limit. I first considered a left intermediate pose at (-0.15, -0.06, 1.08) m, estimating its distance as 0.214 m. For the right arm, (0.22, -0.02, 1.08) m initially seemed about 0.254 m away, but the changes from (0.43, -0.14) m are 0.21 m, 0.12 m, and 0.114 m vertically, giving 0.265 m, also too far. I will instead use the right target (0.24, -0.03, 1.065) m, with change magnitudes of 0.19, 0.11, and 0.099 m and distance about 0.241 m. For the left arm, I will use (-0.15, -0.06, 1.075) m from (-0.291, -0.211, 0.963) m, with changes of 0.141, 0.151, and 0.112 m and estimated distance 0.237 m. The left pepper’s path passes over the watch near x = -0.15 m, y = -0.128 m, but after raising, the pepper bottom should be around z = 0.9 m, above the objects. The middle basket’s front rim may be near y = -0.02 m. The left intermediate target at y = -0.06 m remains in front of it, with the pepper bottom around z = 0.89 m at end-effector z = 1.075 m. I am confident enough in this clearance to use 15 steps, keeping both grippers closed and their downward orientation fixed. At an estimated position rate of 0.01 m per step, a 0.23 m target may take 23 steps, so I will inspect after these 15 steps before continuing. There could be a collision later if both arms enter the middle basket together. The proposed final x positions of ±0.055 m give only 0.11 m separation, while each gripper may be 0.09 m wide and the fingers with a pepper about 0.08 m wide. Keeping the left at x = -0.065 m and the right at +0.065 m would give 0.13 m separation, which seems adequate. The link6 bodies may be about 0.07 m wide, and the fingers close across world X. A closed gripper may be about 0.06 m wide, with each object also spanning about 0.06 m; their edges could touch at center separation 0.12 m. I could place them sequentially, holding the right arm high to avoid interference. For now, I will move both arms to their intermediate poses.

In the high-camera view, the yellow pepper appears over the left basket’s edge at pixel (204, 216), although the left end effector is at world x = -0.203 m, y = -0.121 m, in front of that basket. The red pepper appears over the right basket’s front edge at pixel (476, 175). Both objects are high enough that the motion appears safe. I initially planned to finish moving to the intermediate targets: (-0.15, -0.06, 1.075) m for the left arm and (0.24, -0.03, 1.065) m for the right. However, I could skip those intermediates and move directly above the middle basket. For the left target of (-0.065, 0.055, 1.075) m, I estimate the distance from the current pose as sqrt(0.138² + 0.176² + 0.046²) = 0.228 m, within the 0.25 m limit. For a proposed right target of (0.065, 0.055, 1.065) m, my estimate is sqrt(0.21² + 0.112² + 0.024) = 0.239 m, also within the limit. Does the right-arm path from x = 0.275 m, y = -0.057 m to x = 0.065 m, y = 0.055 m cross in front of the middle basket? The pepper’s bottom is high enough that this appears safe. The left pepper may cross above a watch, but it also appears to have clearance. The final gripper centers would be 0.13 m apart, and the arm bodies may remain high enough to avoid interference. I will move directly inward for 15 control steps, then inspect the result.

Both arms had identical precheck position errors of about 102 mm. Perhaps the direct targets were too far for the local solver to reach from the current joints in one precheck, even though they were within the 0.25 m limit. Could the solver’s iteration behavior be responsible? I should return to the closer intermediate poses I originally planned. The left target is (-0.15, -0.06, 1.075) m, a change of (+0.053, +0.061, +0.046) m from its measured position. The right target is (0.24, -0.03, 1.065) m, a change of (-0.035, +0.027, +0.024) m. These nearer targets will likely pass the precheck. I will use eight control steps.

The left wrist view shows the blue basket’s right edge at the bottom, with the yellow pepper still over the table to the left of the middle basket. In the right wrist view, the red basket occupies much of the top, and the blue basket is visible at the left edge. I should move both arms inward along X and back toward y = 0.055 m. For the left arm, moving from the current (x, y) = (-0.172, -0.088) m to (-0.065, 0.055) m would require changes of (+0.107, +0.143) m. For the right arm, moving from (0.242, -0.035) m to (0.065, 0.055) m would require changes of (-0.177, +0.09) m. I estimate the target distances as 0.18 m for the left and 0.20 m for the right, both within the 0.25 m limit. Why did the previous IK precheck fail with about 102 mm of position error? Perhaps reaching toward the middle basket at x = 0 m requires extension near a singularity. The middle basket is likely reachable by both arms, but I am not certain. Could simultaneous targets cause the precheck to fail? The identical errors are unusual; perhaps the exactly mirrored targets caused the joint search to stall near a singular configuration. The intermediate approach worked, though. I will use nearer targets: (-0.09, 0.01, 1.075) m for the left arm and (0.12, 0.02, 1.065) m for the right, with estimated distances of 0.11 m and 0.14 m. I will use 10 control steps, then make a smaller final move. The peppers should clear the blue basket’s rim: with an end-effector height of 1.06 m and a pepper extending about 0.18 m below it, the pepper bottom would be at approximately 0.88 m, above the estimated rim height of 0.84 m.

Both arms failed the precheck when moving toward positive Y. Could the downward orientation farther along Y require a different arm configuration, or could the local IK be near a singularity? Perhaps I should try gradual targets about 0.02 m away. The left end effector is currently at (-0.172, -0.088, 1.053) m. Its earlier intermediate target, (-0.15, -0.06, 1.075) m, is already close and passed the precheck for the eight-step action, but the arm did not reach it. I should first continue toward that same target. The right intermediate target, (0.24, -0.03, 1.065) m, is also close and should be reachable. I will use six control steps toward the original intermediate poses, then reevaluate.

In the high-camera view, the yellow pepper appears over the left basket rather than the middle basket, so I need to move it inward. Perhaps joint limits make it difficult for the arms to maintain the downward orientation while moving toward the center. They may need a different orientation; could tilting the grippers inward help? The downward pose may also constrain the elbow near the body. The left end effector is currently at (-0.156, -0.07, 1.067) m. The previously attempted target at (-0.09, 0.01, 1.075) m moves inward along +X and forward along +Y. Is that moving away from the base? I estimate the left base’s x and y coordinates as (-0.3, -0.4) m, with its height unknown. The target should be reachable, but the local IK search may be near a singularity in the current joint configuration with the gripper exactly downward. I will try smaller increments of at most 0.05 m. The next targets will be (-0.135, -0.04, 1.075) m for the left arm, with roughly 2–3 cm changes in its horizontal coordinates, and (0.22, -0.005, 1.065) m for the right arm. I will use four control steps while retaining the downward orientations and closed grippers.

The latest precheck position errors are only about 6 mm for the left arm and 8.5 mm for the right, close to tolerance. I initially wondered whether a slight increase in z would help, but the left end effector is already at z = 1.067 m. Could the arm be near its maximum vertical reach, or could the base-link geometry be relevant? The ARX arm’s reach might be around 0.5 m. The target at x = -0.135 m, y = -0.04 m, z = 1.075 m may be far from the shoulder. The initial end-effector height was about 0.922 m. Does the fully downward gripper orientation reduce reach? An earlier precheck did pass at z = 1.075 m and y = -0.06 m. Lowering rather than raising the end effectors may help them move inward and forward. I could lower to z = 1.0 m while moving; I estimate that a pepper’s bottom would then be at z = 0.82 m, perhaps just enough to clear the basket rim. Angling the grippers inward is another possible way to reduce the required reach. The tiny rotation errors alongside the position failures suggest that the targets may be near a reach limit, so I will try lowering first. I will target the left arm at (-0.135, -0.04, 1.02) m and the right arm at (0.22, -0.005, 1.02) m. My rough target-distance estimate is 0.09 m. I will keep both grippers closed and pointing downward, and use five control steps.

The lowering motion succeeded. I should continue gradually toward the middle basket, perhaps at z = 0.99 m. For the next action, I will target the left end effector at (-0.10, 0.0, 1.0) m and the right at (0.17, 0.025, 1.0) m. These targets change the left position by (+0.035, +0.04, -0.02) m and the right by (-0.05, +0.03, -0.02) m. I will use six control steps; these targets should pass the local kinematic check.

I should try a smaller target or lower the end-effector height to z = 0.98 m. The precheck position errors of about 10.6 mm suggest that the targets are close to feasible. I could try z = 0.97 m with horizontal changes of about 0.02 m, but at an end-effector height of 1.0 m, I estimate the pepper bottoms at z = 0.817 m and the basket rim perhaps at z = 0.82 m. Lowering to 0.97 m could risk contact with the rim while crossing. Could tilting the grippers slightly change the arm geometry and improve reach while allowing them to rise? The exactly downward orientation seems to encounter a reach limit when moving inward along X and forward along Y. Perhaps the arms need more elbow bend, and lowering could help. I will try small targets at z = 0.98 m, with the left arm at x = -0.11 m, y = -0.015 m and the right arm at x = 0.19 m, y = 0.01 m, using four control steps.

The left gripper’s opening command increased from 0.431 to 0.564 despite remaining commanded closed, while the right command decreased to 0.36. Could contact have forced the left fingers apart? The left orientation also deviated slightly, and the yellow pepper appears at the blue basket’s left rim. In the left wrist view, it looks much larger and has shifted down and left, with the right finger occluding it. It may be slipping because of rim contact. I should stop and replan. The left arm stopped short of its target: its measured z is 0.999 m rather than 0.98 m, and y is -0.025 m rather than -0.015 m, with a slight quaternion deviation. This suggests contact may have prevented the descent. In the high-camera view, the yellow pepper is near pixel (258, 185), while the blue basket’s left wall is near pixel x = 260. Its bottom may be touching the rim. However, the opening value is the controller’s latest interpolated command, not a measured finger gap. I do not understand why it increased under a closed command. It could involve interpolation, contact constraints, or physics, but I should not assume that it proves the gripper was forced open or that the pepper slipped. I should retreat the left arm upward and slightly left to regain clearance. The red pepper appears near pixel (425, 175), above the red basket’s center. Its wrist view has the red wall filling the background, perhaps simply because it is near that basket. I can hold the right arm while recovering the left. One possibility is to raise the left end effector to z = 1.05 m without changing x or y, then change orientation and lower after centering over the middle basket. Higher targets previously caused IK failures, though, so raising in place may also be difficult. Retreating toward more negative y while raising to z = 1.04 m may be easier. Could I move directly into the blue basket from the current position? The left end effector is at x = -0.117 m, y = -0.025 m. I estimate the middle basket’s center at x = 0 m, y = 0.055 m, its inner left boundary around x = -0.105 m, and its front boundary around y = -0.035 m. That would put the pepper center 0.012 m outside the left boundary, near the front-left corner, consistent with hitting the wall. It needs at least about +0.05 m in both x and y to move toward the center. The current orientation may make that difficult to reach. Tilting the fingers inward could let the object extend beyond the end effector in x, or another downward yaw could improve the arm configuration. With the fully downward wxyz quaternion [0.5, -0.5, 0.5, 0.5], the peppers sit beneath the end effectors. Earlier, the arms were around x = ±0.3 m and y = -0.2 m. Moving toward the center and farther back extends their reach. An ARX X5 arm might be about 0.55 m long, with bases perhaps at x = ±0.3 m, y = -0.55 m; reaching x = 0 m, y = 0.05 m could then require about 0.6 m. These are only hypotheses. The task should be solvable, and either arm ought to have a symmetric route to the middle basket. My basket localization may also need refinement. The high-camera pixel (320, 190), intersected with z = 0.75 m, gave y = 0.055 m. If the basket bottom were at z = 0.79 m, that estimate would instead be y = 0.017 m, closer to the robot. Could its interior bottom be at z = 0.78 m, with its center near image y = 183? Could the table be at z = 0 m? Given the end-effector height of about 0.922 m, z = 0.75 m still seems likely for the table. The basket may rest there with a rim at z = 0.84 m. Its rear top is near image y = 140 and front bottom near y = 211; its apparent geometric center is near y = 177, but those points have different heights. Its world center might be around y = 0.04 m, making x = 0 m, y = 0.04 m a possible destination. I briefly considered placing both peppers sequentially with the left arm, perhaps using a handoff from the right. The right pepper still has to reach the middle basket, so placing it in the right basket would not help. A handoff probably is not necessary. I should use measured poses, visible geometry, recorded joints if useful, and IK feedback to understand the reach limits rather than access simulator internals. Lowering helped the arms reach inward, but the left arm now appears to have caught the rim at z = 0.999 m before reaching the requested 0.98 m. Once the pepper is over the interior, lowering should be possible. The difficulty is crossing the rim high enough while avoiding the reach limit at higher end-effector positions. Changing the carry angle may solve both problems. If the fingers point forward rather than downward, the pepper would sit forward of the end effector, with its bottom perhaps only about 0.03 m below it rather than 0.18 m. That could clear the rim at a lower end-effector height. Returning to the initial 90° Z orientation would point the fingers horizontally along +Y, but rotating that far might cause slipping. The pepper might remain held through friction, although I am uncertain. A 45° forward-and-down tilt seems a better alternative. For that tilted carry pose, I could use the intermediate wxyz quaternion [0.654, -0.27, 0.27, 0.654], with local X approximately [0, 0.707, -0.707] in the environment frame. The pepper center would be forward of the end effector and about 0.1 m below it. At end-effector z = 1.0 m, its bottom might be around z = 0.9 m. A +0.1 m shift in the object’s y position would let an end effector at y = -0.05 m place the object near y = 0.05 m without reaching as far. Currently, the left end effector is at y = -0.025 m and the pepper center may be around y = -0.02 m, requiring about +0.07 m. Rotating into the intermediate pose could shift the pepper forward about 0.08 m while lifting its bottom about 0.05 m. I could then release it over the basket at an angle rather than requiring a vertical pose. A later pair of tilted targets could be x = ±0.07 m, y = -0.04 m, z = 1.0 m, giving 0.14 m separation between the grippers. The right end effector would move from x = 0.196 m toward 0.07 m, and the left from -0.117 m toward -0.07 m. Before that, I considered recovering and rotating the left at approximately (-0.12, -0.055, 1.02) m, while tilting the right at (0.16, -0.02, 1.02) m. Rotation near the rim could itself cause contact, so I should first retreat the left and hold the right, then reorient. Releasing now is not acceptable: the yellow pepper could fall onto the rim or into the wrong basket. It still appears between the gripper and the blue wall in the high view, while the wrist view shows its body down and left, possibly still touching the fingers. The increased opening command could accompany a rotation in the grasp, but that remains uncertain. I considered closing for two steps at the current or raised pose before lifting back. For the immediate recovery, I will command the left end effector to (-0.135, -0.065, 1.04) m with the downward quaternion [0.5, -0.5, 0.5, 0.5] and the gripper closed. This retreats y by 0.04 m, raises z by 0.041 m, and changes x by -0.018 m; my estimate places it within 0.06 m of the current pose. It should be feasible because it retreats from the rim. I will hold the right arm at its current measured pose with its gripper closed and use five control steps. This should move the yellow pepper back and left, away from the blue rim, before changing the carry angle.

The yellow pepper appears secure again, with the left gripper’s opening command at 0.402 and no obvious damage. I will rotate both grippers toward the intermediate wxyz quaternion [0.653, -0.2706, 0.2706, 0.653]. I first considered a left target at (-0.09, -0.06, 1.02) m. In this orientation, the finger axis is approximately [0, 0.707, -0.707], and the object center may be offset from the end effector by +0.10 m in Y and -0.10 m in Z. That would put the yellow pepper near x = -0.09 m, y = 0.04 m, over the middle basket’s left side. Its bottom might be around z = 0.89 m, which seems safe. A matching right target at (0.09, -0.06, 1.02) m would put the red pepper near y = 0.04 m and leave the end effectors 0.18 m apart. I might be able to release directly over the basket from this tilted orientation. The change from downward to intermediate orientation is about 0.785 rad, within the 1.0 rad limit. For those proposed targets, I estimate the right position change as (-0.107, -0.07, +0.039) m, with a distance of 0.134 m, and the left change as (+0.044, +0.003, -0.02) m, with a distance of 0.049 m. The peppers should swing forward and upward during rotation, improving clearance. However, the red pepper is currently over the red basket. Would rotating forward along world +Y take it away from the blue basket and toward the red basket’s back wall? Its bottom would rise, but I should move the right arm left toward the middle basket simultaneously so the path arcs over the gap. I also considered a tilted right target at (0.14, -0.04, 1.02) m, but that might leave the pepper at the middle basket’s right edge. With an estimated blue-basket inner right boundary at x = 0.11 m and pepper radius of 0.035 m, the pepper center needs x ≤ 0.075 m, suggesting a final x of 0.07 m. There is still a possible clearance issue during rotation near the red basket wall. In the high-camera image, the red basket spans approximately pixel x = 384–515, the blue basket spans x = 260–378, and the red pepper is near (420, 175). Moving left by 0.126 m toward x = 0.07 m while rotating forward should cross the blue basket’s right wall at a safe height. For the immediate action, I will use 10 control steps toward left and right targets of (-0.08, -0.06, 1.02) m and (0.08, -0.06, 1.02) m, keeping both grippers closed and using the intermediate orientation. The rotation may not finish in those steps, but the tilted pose may make the local kinematic precheck feasible.

Both peppers appear to be over the blue middle basket. The right wrist view shows the red pepper in the center, with the blue basket beneath it and to the left and the red basket to the right. It is likely safe to release both peppers now. The end-effector heights are approximately z = 1.02 m. I estimate the pepper bottoms at z = 0.88 m and the basket floor at z = 0.75 m, giving a drop of about 0.13 m. That seems acceptable for placement inside the basket. I could lower them slightly while maintaining the tilt, but that would risk contact with the rim, so I will release from the current height. The left and right gripper opening commands are 0.399 and 0.42, respectively, rather than fully closed. Setting gripper_closed to false should spread the fingers. I considered opening for three control steps and then inspecting, or perhaps five if command interpolation leaves the peppers held. I will use four steps to open both grippers while holding their current poses, then inspect the result.

The calculated black watch position is x = 0.283 m, rather than my earlier estimate of 0.39 m. The right arm initially had x = 0.3 m and y = -0.35 m, with its fingers extending forward to about y = -0.19 m, so the watch being beneath or near that gripper makes sense. The green car’s image center may be around (346, 270) pixels. The leftmost watch’s center in the high-camera image is around (250, 254) pixels. I used z = 0.765 m as the estimated midpoint height of the watch band. I will move the left gripper to the pre-grasp position [-0.148, -0.131, 1.03] m above that watch and the right gripper to [0.054, -0.172, 1.03] m above the green car. Both grippers will remain open and return to the downward orientation, using quaternion [0.5, -0.5, 0.5, 0.5] in wxyz order. I will use 12 control steps.

The objects are clearly visible. The leftmost watch is centered near (u = 321, v = 185) pixels in the left wrist view, so its X and Y alignment is probably close. The green car is near (u = 287, v = 303) pixels in the right wrist view. Its leftward offset likely reflects the right arm not yet reaching its target position and orientation. I should finish the downward alignment. The watch ring appears circular, with a diameter of about 100 pixels in the wrist image. The open gripper tips are at approximately u = 125 and u = 515 pixels, giving a 390-pixel gap. At a possible pre-grasp depth of 0.25 m, a ring diameter of 0.04 m would appear about 63 pixels wide; the observed 100-pixel diameter suggests a depth of about 0.16 m. I can grasp the ring’s outer sides along the camera’s horizontal direction, corresponding to world X, with its center at u = 320 pixels. A contact pose at end-effector z = 0.91 m would put the fingertips at z = 0.752 m. I estimate the watch ring’s height at 0.02 m and its center at z = 0.765 m, so that contact height looks suitable. For the green car, reaching the full target at x = 0.054 m, y = -0.172 m with the downward orientation should bring its center toward u = 320 pixels, but I am unsure of the expected vertical pixel coordinate. With end-effector z = 1.03 m and car-center z = 0.775 m, perhaps v would be around 150 pixels if X and Y were aligned. Is the current v = 303 pixels caused by the Y mismatch between the measured end-effector y = -0.134 m and target y = -0.172 m? Would an object farther toward world -Y appear lower in the image? The downward camera looks toward -Y, and an object farther toward -Y, toward the robot, would give a camera-to-object Y component of -0.089 m rather than -0.051 m. Would its camera Y coordinate be positive? My tentative expression, 0.077 - 0.11 = -0.033, is negative, so the expected vertical projection remains unclear. I will use the recorded calibration to infer the green car’s world center from its wrist-image pixel location, considering z = 0.78 m; the calculation will use z = 0.775 m. I will also estimate the watch center using z = 0.765 m.

The calculated object coordinates are consistent with the earlier estimates. I will target the left gripper at x = -0.146 m, y = -0.136 m over the leftmost watch and the right gripper at x = 0.055 m, y = -0.171 m over the green car, with both grippers fully downward. The watch is already well aligned horizontally at u = 321 pixels. Moving the right gripper from its current x = 0.07 m, y = -0.134 m to the new target should finish its alignment. I will use six control steps with both grippers open.

At the left end-effector height of z = 0.996 m, the watch center is at wrist-image coordinates (u = 318, v = 165) pixels, and the green car center is at (u = 320, v = 160) pixels. Both remain centered, so I will continue the open-gripper descent for three control steps.

The watch is now centered at wrist-image coordinates (320, 199) pixels, with horizontal bounds from x = 240 to 400 pixels and a width of 160 pixels. The open fingertips are at x = 125 and 515 pixels, leaving a gap of 390 pixels. At the final end-effector height of z = 0.915 m, the watch may appear about 230 pixels wide, so the gap should still be sufficient. The car spans approximately x = 190–460 pixels, giving a width of about 270 pixels within the 390-pixel gap. The fingers will need to close substantially to grasp both objects. I will continue the open-gripper descent for three control steps.

The watch band’s outer edges now span x = 209–431 pixels, a width of 222 pixels, while the fingertips are at x = 125 and 515 pixels. The car spans x = 158–568 pixels, a width of 410 pixels including its spoiler. The fingers’ inner edges are near x = 126 and 515 pixels. Could the right finger be overlapping the spoiler near (540, 225) pixels? The open right finger is at x = 515 pixels, while the spoiler reaches x = 568 pixels, so the finger might be above part of it. The high-camera view appears to show the fingers around the car’s center, but contact is uncertain. At the right end-effector height of z = 0.926 m, the fingertips are around z = 0.768 m, while the car body’s top is around z = 0.79 m. The fingers are therefore already low enough that they could push the spoiler. In the right wrist view, the black finger’s inner edge is near (516, 255) pixels, adjacent to the spoiler extending to approximately (570, 223) pixels; perhaps there is no contact. The main body spans x = 190–480 pixels at its middle and fits within the open gap. The wider spoiler could encounter a finger during further descent if the grasp orientation is unsuitable. Should I rotate the gripper’s yaw so that its closing direction is perpendicular to the car’s long axis? It currently closes along world X, and the car’s long axis appears diagonal, about 20° from vertical in the image. The main body is narrower, while the rear spoiler at the top extends across approximately x = 300–560 pixels. The fingers seem to be around image y = 250 pixels, with their tips near y = 255 pixels, which might put contact near the spoiler. However, the fingertip projection is fixed at approximately v = 275 pixels, and the car spans v = 68–439 pixels. The pads extend downward toward the bottom of the image, so closing near the car’s center at v = 275 pixels may contact the middle body rather than the spoiler near v = 130 pixels. The fingers may be only about 0.04 m long along local Z, which corresponds to world Y, limiting the relevant vertical image range. A midbody grasp could avoid the spoiler. The remaining descent to z = 0.915 m is only about 1 cm. The car may already be at a suitable grasp height: its fingertips are at z = 0.768 m, with the body bottom at the table height of z = 0.75 m and its top around z = 0.80 m. Closing now might grasp the body’s sides. The watch’s end effector is at z = 0.927 m, with fingertips around z = 0.769 m and an estimated ring height of 0.02 m. I could close both grippers now to avoid further descent toward the table. The earlier pepper grasps worked at end-effector z = 0.933 m, with fingertips at z = 0.775 m and the pepper body center around z = 0.785 m. For the watch, though, the estimated center is at z = 0.765 m, and fingertips near z = 0.752 m would ideally put the pads low enough alongside the ring. The current fingertips at z = 0.769 m are near its center height, while the pads extend upward, so they may only contact near the ring’s top. I will descend toward z = 0.915 m before closing. Three more control steps would likely reach that height, with a remaining left-arm height difference of 0.012 m, and the car’s end effector would also target z = 0.915 m. Two steps might leave the height near z = 0.919 m. I will use two steps toward z = 0.915 m to be cautious, keeping both grippers open.

The descent was only about 0.004 m. Could contact be slowing it? The target was z = 0.915 m, but both end effectors are at z = 0.923 m after two steps, compared with the earlier descent rate of about 0.011 m per step. The left quaternion also deviates slightly. The watch and car appear unchanged in the high-camera view. In the right wrist view, the right finger’s inner edge at pixel (516, 255) does not seem to touch the spoiler’s outer edge at x = 569 pixels. However, the green car’s left body edge near (149, 344) pixels is close to the left finger near (126, 257) pixels and its angled inner edge. Perhaps that finger is contacting the front of the car. The small orientation deviation could indicate fingertip contact with the table. Could the table height be z = 0.765 m rather than the assumed 0.75 m? With the end effector at z = 0.923 m, I estimate the fingertips at z = 0.7654 m, which should clear a table at z = 0.75 m. I briefly considered whether the finger geometry might extend 0.18 m, putting the tips at z = 0.743 m and causing table contact, but the supplied farthest forward extent is approximately 0.1576 m, so that explanation does not fit. Perhaps the open fingers are resting on the objects instead. Could the open gap be only 0.04 m? From the visible black outer fingers, I might estimate an open width of 0.06 m against a car width of 0.07 m. The opening command is currently 1, though the native open gap might be around 0.08 m. The watch’s estimated outer diameter of 0.05 m should fit; the car’s width might be 0.065 m, which is closer to the available gap. These contact and gap estimates remain uncertain. I can close at the current end-effector height of z = 0.923 m rather than descend farther. If the fingertips are near z = 0.765 m, the pads should lie at or above that height, suitable for the estimated watch center at z = 0.765 m. The car’s estimated body top is at z = 0.79 m and its center at z = 0.775 m, also suitable. I will hold the current poses and close both grippers for three control steps.

The fingers have closed around the sides of the watch and the car. I will make a small test lift with both end effectors targeting z = 0.975 m for three control steps, keeping the grippers closed and their orientations steady, to verify the grasps.

Both objects lifted with the grippers. In the high-camera view, the leftmost watch may have moved from pixel (250, 254) to (249, 250), and the green car may have moved from y = 273 to y = 269 pixels. The objects remain stable in the wrist views, although the car has rotated from diagonal to vertical in the image. That suggests the grasp rotated it about Z to align with the closing direction, which seems acceptable. I need to place the watch in the left basket and the green car in the right basket. I estimate the outer basket centers at x = -0.32 m and +0.32 m, both at y = 0.055 m. I could carry them downward or tilt them forward to reduce the required reach. The left basket is closer to the left base than the middle basket, so a downward carry at z = 1.02 m may be feasible. The watch bottom is approximately 0.17 m below the end effector; at end-effector z = 1.0 m, its bottom would be around z = 0.83 m, close to a possible rim height of 0.84 m. I could use the tilted intermediate carry pose as before or raise to z = 1.06 m. A direct downward left-arm target at (-0.32, 0.055, 1.04) m from (-0.147, -0.138, 0.958) m has a planned change of (-0.173, +0.193, +0.082) m and an estimated distance of 0.272 m, exceeding the 0.25 m limit. The right basket target has x = 0.32 m and y = 0.055 m; from the current right pose (0.054, -0.173, 0.959) m, my planned change is (+0.266, +0.228, +0.08) m, with an estimated distance of 0.36 m. Both arms therefore need intermediate targets. I initially considered keeping the current nearly downward orientations and staging in front of the baskets at (-0.28, -0.06, 1.06) m for the left arm and (0.22, -0.06, 1.06) m for the right. My distance estimates for those staging targets are 0.158 m and 0.194 m, respectively, and the paths appear safe. I could then tilt forward while moving to release poses at (-0.32, -0.04, 1.02) m and (0.32, -0.04, 1.02) m. With the tilted pose, I estimate the object’s Y coordinate as the end effector’s Y coordinate plus 0.1 m, so end-effector y = -0.04 m would put the object near y = 0.06 m. This reduces the reach needed and keeps the objects high: I estimate the outer basket rims at z = 0.84 m and the tilted object bottoms around z = 0.88 m. Instead, I can skip the downward high staging pose and tilt directly while moving to staging positions at z = 1.05 m. The left target will be (-0.28, -0.06, 1.05) m, a planned change of (-0.133, +0.078, +0.092) m and an estimated distance of 0.18 m. The right target will be (0.22, -0.06, 1.05) m, a planned change of (+0.166, +0.113, +0.091) m and an estimated distance of 0.221 m. The intermediate orientation is about 0.8 rad from the current nearly downward orientation. As the grippers rotate forward, the objects should swing toward +Y and upward, toward the baskets and clear of the table objects. The held green car’s path from x = 0.054 m to 0.22 m and y = -0.17 m to -0.06 m could pass near the red car, which may be at x = 0.212 m, y = -0.112 m. It could collide if carried too low, but raising to z = 1.05 m and tilting should put the held car’s bottom around z = 0.9 m, above the red car at approximately z = 0.8 m. I briefly considered whether the watch’s path might pass above the second watch at x = -0.04 m, but the held watch is moving left, away from it. Keeping a downward orientation during staging might avoid uncontrolled watch rotation, but its grasp looks stable enough to tilt. I will use the intermediate tilted orientation, keep both grippers closed, and execute 15 control steps.

The right gripper’s opening command is now 0.0, and the green car is on the table near pixel (371, 237) in the high-camera view. It appears to have slipped during the carry or rotation before reaching the right basket. Why is the opening command 0? The gripper is fully commanded closed but has lost the object, likely during rotation. I need to recover it. The right end effector is currently at x = 0.179 m, y = -0.087 m. The car’s image position might correspond to world x = 0.11 m, y = -0.04 m, but I should check that estimate. The left watch remains secure above the white basket, whose interior is visible in the left wrist view. The left end effector is at [-0.279, -0.061, 1.049] m and has reached the tilted orientation. I estimate the watch’s offset along +Y at 0.11 m, placing it near world y = 0.05 m and x = -0.279 m. That is toward the basket’s right side but should be inside, given an estimated basket center at x = -0.32 m and inner width of 0.2 m. I can release the watch by opening the left gripper for four steps. The green car appears near the front of the red basket at high-camera y = 238 pixels, possibly farther back than its original y = 270 pixels. I considered opening the right gripper and moving toward it immediately. Using pixel (371, 240) and an assumed object height of z = 0.775 m might give world x = 0.110 m, y = -0.075 m; I still need to calculate that. The right end effector is at [0.179, -0.087, 1.031] m, with the closed fingers tilted forward and downward. The car appears near pixel (371, 238), below the gripper near (400, 170). Another tentative estimate puts the car at world x = 0.11 m, y = -0.067 m, likely within 0.1 m of the end effector. I should avoid moving the closed right fingers into the dropped car before refining its position. Instead, I will hold both measured poses and open both grippers for four steps, releasing the watch and preparing the empty right gripper for recovery. Opening the empty right gripper in place above the red basket’s edge appears safe. I will inspect the next observation before regrasping the car.

The watch is inside the left basket. The green car appears centered near pixel (371, 238), with its long axis now along world Y. I should estimate its world X and Y coordinates from the high-camera calibration using an assumed height of z = 0.775 m. The previous red-car pixel location of (420, 244) gave approximately x = 0.212 m and y = -0.112 m. Mentally, I estimate the green car at x = 0.110 m and perhaps y = -0.098 m, but I should check this with a script. The bottom edge visible in the right wrist view might also help refine its location. The left arm can approach the second watch while the right arm regrasps the green car. The second watch was estimated at x = -0.0394 m, y = -0.0889 m and appears unchanged. The left end effector is currently at (-0.279, -0.061, 1.049) m, tilted with its gripper open. A downward pre-grasp target at (-0.039, -0.089, 1.03) m would require a position change of approximately (+0.24, -0.028, -0.019) m, with a distance of 0.242 m, close to the 0.25 m limit. The orientation change would be about 0.78 rad. The precheck might fail because this is a large inward move toward the center, although the watch is closer at y = -0.089 m and z = 1.03 m than the earlier middle-basket targets. Since a similar direct approach failed earlier, I could first stage the left arm at (-0.15, -0.09, 1.03) m. For the right arm, I tentatively considered a green-car target near x = 0.11 m, y = -0.09 m. Its current end-effector position is (0.179, -0.087, 1.031) m, already above the car but tilted, with the gripper open. A downward alignment target at (0.11, -0.098, 1.03) m seems straightforward. Before moving, I will calculate the green car’s position more precisely from the high-camera image and recheck the second watch’s location.

The green car’s estimated current position is x = 0.109 m, y = -0.097 m. The right end effector is at x = 0.179 m, y = -0.087 m and is tilted, with the fingers pointing forward and downward, so its tips may be over the red basket rather than the car. I will move it to (0.109, -0.097, 1.03) m in a downward orientation. For the left arm, I could move directly from x = -0.279 m toward the second watch at x = -0.039 m. I initially considered a downward intermediate pose at (-0.15, -0.09, 1.03) m for 10 steps, while allowing eight steps for the right arm’s alignment. These motions are independent, and the left arm could approach the watch after reaching its staging pose. Another option is to try the direct left-arm target for 12 steps; a failed precheck would consume no control steps. It may pass because the watch target is at y = -0.089 m and z = 1.03 m, requiring less reach than the earlier middle-basket target at y = 0 m. However, the estimated position distance is 0.242 m, close to the maximum, and the IK check might fail. I prefer the staging approach, which I expect to be feasible. I will use a left target of (-0.14, -0.09, 1.03) m, with an estimated distance of 0.142 m, and the right target of (0.109, -0.097, 1.03) m. Both grippers will remain open and point downward, and I will use 12 control steps.

The second watch is at the right edge of the left wrist view, near (u = 559, v = 171) pixels, so the left gripper needs to move about +0.1 m along world X. The green car is nearly centered in the right wrist view at (329, 173) pixels. The nearby red car raises a possible collision concern during the green-car descent. It appears near (535, 210) pixels, while the open right finger is near (515, 255) pixels and the red car’s front wing extends near (600, 260) pixels. The gripper center is at world x = 0.11 m, and the red car’s center is around x = 0.212 m, a separation of 0.102 m. I initially estimate the right finger and the red car’s leftmost front-wing edge both near world x = 0.16 m. In the wrist image, the red car’s leftmost point is around (448, 150) pixels, so the finger might touch its lower portion. I should monitor clearance during descent. I could rotate the green-car gripper to close along world Y, perhaps along the car’s long axis, to avoid the red car. However, the car’s length of about 0.1 m exceeds the estimated maximum opening of 0.08 m, so that grasp would not fit. Other options are to offset the grasp toward the green car’s front or rear body, or move the red car first. The current open gripper may fit between the green car, blue basket, and red car. I can descend slowly and check for contact; if the right finger pushes the red car, I could recover it later. My preferred grasp remains at world x = 0.109 m, y = -0.097 m, closing along X. With an estimated green-car width of 0.05 m and open gap of 0.08 m, I estimate the right finger at x = 0.149 m and the red car’s leftmost edge at x = 0.17 m, leaving about 2 cm of clearance. That seems sufficient. For this action, I will align the left gripper over the second watch at x = -0.039 m, y = -0.089 m and finish both downward orientations. The left arm’s X target is +0.105 m from its current x = -0.144 m, within the motion bound. The right arm may need about four control steps to finish its downward pose, while the left may need eight, so I will use eight steps for the combined action.

The watch center is at (u = 369, v = 147) pixels in the left wrist view. The left end effector is currently at x = -0.059 m and needs an approximately +0.02 m correction along X to reach the target x = -0.039 m. The green car is at (u = 318, v = 133) pixels in the right wrist view, so it is nearly centered. The right end effector is at x = 0.114 m, with a target of x = 0.109 m; the car’s x coordinate may be around 0.109 m. I will make the final small alignment corrections for both arms, targeting left x = -0.039 m and right x = 0.109 m, using four control steps.

Unexpectedly, the right end effector moved +0.009 m along X instead of the intended -0.005 m correction, and +0.004 m along Y, with some orientation deviation. Could it have collided with the red car or blue basket? At the pre-grasp height of z = 1.03 m, I estimate the fingertips at z = 0.87 m, above the objects. Perhaps the tilted gripper contacted the red basket rim near y = -0.09 m, although downward fingertips at z = 0.87 m should clear an estimated front rim at z = 0.83 m. A joint limit is another possibility. The downward target at x = 0.109 m, y = -0.097 m appears free of collisions, so the motion opposite the small requested correction might indicate local IK drift near a singularity. The current right quaternion is [0.511, -0.491, 0.507, 0.489] in wxyz order, a slight deviation from the desired pose. I should use the current measured poses and infer the objects’ current positions. The green car is centered near wrist-image coordinates (295, 137) pixels, suggesting that the right end effector should decrease X by about 0.01 m. Trying an X target near 0.11 m again may eventually bring it into alignment. The watch is centered near (350, 156) pixels in the left wrist view, suggesting an approximately +0.012 m X correction. The left end effector is currently at x = -0.049 m and moved only +0.01 m during the last action, so it still needs to continue toward x = -0.039 m. I could descend while correcting the alignment. The right end effector is at z = 1.031 m, with a possible target of 0.925 m, while the left is at z = 1.028 m and could target 0.923 m. For the green-car regrasp, maintaining the downward orientation and closing at z = 0.923 m, as before, may be better. I also considered a three-step descent toward z = 0.97 m, with left X and Y targets of -0.039 m and -0.089 m and right targets of 0.109 m and -0.097 m. I need to preserve clearance from the red car. The right end effector is currently at x = 0.123 m, while the green car is estimated at x = 0.109 m, giving a -0.014 m offset. Correcting leftward moves the right gripper away from the red car. Increasing the left gripper’s X coordinate moves it toward the green car, but the object centers are about 0.148 m apart, so that appears safe. I will use three control steps with both grippers open to begin descending while correcting the offsets.

The watch center is now at (u = 348, v = 195) pixels in the left wrist view, and the green car is at (u = 292, v = 174) pixels in the right wrist view. Should I adjust the left end effector’s X coordinate by +0.008 m? At an estimated depth of 0.2 m, the watch’s 28-pixel horizontal offset corresponds to about 0.014 m. Moving from x = -0.047 m to the earlier target of -0.039 m gives only +0.008 m, which may be insufficient. If the second watch is actually at x = -0.039 m, why is its image center still at u = 348? A Y or orientation offset might affect the horizontal projection. With the gripper fully downward, image u corresponds directly to world X. The estimated +0.008 m object offset at a depth of about 0.2 m would give 16 pixels rather than the observed 28 pixels; perhaps the depth is closer to 0.12 m. At the current end-effector height of z = 0.999 m, the camera height is about 0.914 m, and the assumed watch height is 0.765 m. Could the optical depth be about 0.168 m? Using 0.008 × 397 / 0.168 gives about 19 pixels, and a small camera-angle effect might account for u = 348. An end-effector X target of -0.035 m might be better. Still, with an estimated watch-band diameter of 0.04 m and finger gap of 0.08 m, an offset of 0.01 m seems tolerable. For the green car, the right end effector is at x = 0.125 m and the estimated object X coordinate is 0.109 m, giving an object offset of -0.016 m. At a depth of 0.17 m, that would project to about -37 pixels, compared with the observed -28 pixels. I should continue toward an end-effector X target of 0.109 m to center it. The Y offsets are small: the left end effector is at -0.081 m versus the watch at -0.089 m, an object offset of -0.008 m; the right is at -0.088 m versus the car at -0.097 m, an offset of -0.009 m. I will continue the centering corrections and descend for another three control steps.

The right end effector’s X coordinate has not corrected at all; it is still 0.125 m despite the target of 0.109 m. Could contact between the right finger and the red car be preventing leftward motion? Moving left should take it away from the red car, though. Perhaps a joint limit near the center prevents the IK solver from reaching the exact target, or the solver is settling at a local minimum. The left end effector is also still at x = -0.047 m despite its target of -0.037 m. Are both arms approaching an inward reach limit? The high, downward poses require them to reach across, but the left arm should be able to reach the second watch near x = -0.039 m. A slight yaw deviation could also contribute to the position error. Alternatively, the prechecks passed, but three control steps may not have been enough for the per-step IK updates to correct X while descending. The joint increments are scaled together to preserve their coordinated direction, so the observed 0.033 m descent may be dominating the motion and leaving the X corrections slow. Once the end effectors reach z = 0.923 m, the lateral corrections can continue. I expect the final three calls to bring them into alignment. The left watch’s center is at u = 357 pixels, and the green car’s center is at u = 287 pixels in their respective wrist views. I should refine alignment after the descent. For now, I will continue for three control steps toward the same targets with both grippers open.

At the left end-effector height of z = 0.932 m, the watch center appears at u = 386 pixels, an offset of +66 pixels from the wrist-image center. The green car appears at u = 300 pixels, an offset of -20 pixels. The watch’s apparent offset has increased as the descent magnifies it. The left end effector is actually at x = -0.049 m despite the target of -0.037 m, and its last X motion was -0.002 m, in the wrong direction. Could contact between the gripper and watch explain this? In the left wrist image, the open fingers are at x = 125 and 515 pixels, while the watch’s outer edges span x = 294–478 pixels around its center at 386 pixels. The right finger’s inner edge is near 515 pixels, leaving a 37-pixel gap, compared with a 169-pixel gap on the left. I estimate that moving the gripper right by about 0.02 m would center it. However, could the watch itself obstruct that correction? The gripper center is left of the watch, and the right finger is closer to its outer side. Moving right at the same height might push that finger against the watch. At end-effector z = 0.932 m, I estimate the fingertips at z = 0.774 m and the watch-ring center at z = 0.765 m, so side contact is possible. Should I lift to reposition, or close with the current offset? Closing from this offset might center the small watch: the right finger would contact first and push it left until the left finger also contacts. That might work, although it could rotate the watch. Ideally, I would have aligned before descending, but the X correction did not arrive, apparently because of IK constraints. There is also a possible basket-clearance issue. The second watch is near high-camera pixel (302, 237), just in front of the blue basket. The left gripper appears near (280, 180), above the blue front wall, with its fingertips down near the watch at image y = 237 pixels. The basket’s front edge is near image y = 209 pixels, so a finger might contact its rim if the Y position is too close. Still, the estimated watch-center y = -0.089 m and basket-front y ≈ -0.02 m give about 0.07 m of separation, which seems safe. The green car spans x = 170–430 pixels between the right wrist image’s fingers at x = 125 and 515 pixels, so its alignment looks adequate. The red car is partly occluded at the far right; the finger near x = 515 pixels may cover its left wing, and contact is uncertain. In the high view, the red car remains at approximately (420, 244), while the right fingertip appears near (425, 203), behind or above it. This may be clear. I could close on the green car now at end-effector z = 0.933 m. The earlier grasp worked at z = 0.923 m, so this is 0.01 m higher, but the pads may still make suitable contact. I considered a final two-step descent to z = 0.923 m, perhaps with left x = -0.03 m and right x = 0.109 m, though even that small descent could cause contact. Given the watch’s offset, I should correct its alignment before closing. Another option is lateral alignment without further descent: left target x = -0.025 m, y = -0.089 m, z = 0.932 m, a planned change of +0.024 m in X and -0.008 m in Y, with the exact downward orientation. The precheck may pass, and the actual lateral correction may progress better without a competing Z motion. I will align the left gripper while independently closing the right gripper on the green car. Although the car’s end-effector height is 0.933 m rather than the previous grasp height of 0.923 m, I estimate its fingertips at z = 0.775 m, matching the car center at z = 0.775 m, with the pads extending upward. That seems suitable. For the immediate action, I will keep the left gripper open and target (-0.027, -0.089, 0.932) m with the downward wxyz quaternion [0.5, -0.5, 0.5, 0.5]. I will hold the right arm’s current pose and command it closed for three control steps, then inspect both arms.

The right fingers have closed around the centered green car’s body. The left watch’s alignment is better now, with its center at u = 338 pixels. The left end effector is at x = -0.041 m, close to the watch’s possible x position of -0.039 m. The watch ring spans u = 244–433 pixels, between the open fingers at u = 125 and 515 pixels, so I can close the left gripper at its current height of z = 0.929 m. I will close the left gripper while making a small test lift of the green car toward z = 0.98 m with the right gripper kept closed. I will perform both actions simultaneously for three control steps, then check whether the car is securely held.

The green car lifted and looks stable in the high-camera view; its bottom is at image y = 249 pixels compared with 259 pixels previously. The watch still appears on the table, although the left gripper is closed around it. I need to test-lift the watch toward end-effector z = 0.98 m before transporting it. The right arm could begin moving outward, or remain at its current z = 0.969 m. I should keep the car in the downward grasp orientation throughout transport because it slipped during the previous tilted carry. From the grasp end-effector height of z = 0.933 m and the estimated car-bottom height of z = 0.75 m, I estimate the car bottom at -0.183 m relative to the end effector. At end-effector z = 1.04 m, its bottom would be at z = 0.857 m, above the estimated rim height of 0.84 m. A downward carry toward the red basket center at (0.32, 0.055, 1.04) m may be reachable because the basket is forward and on the same side as the right arm. The previous staging target at (0.22, -0.06, 1.05) m was reachable. I had planned a tilted final target at (0.32, -0.04, 1.02) m, but the car slipped during that carry. Instead, I can keep the gripper downward and use a final end-effector target at (0.32, 0.04, 1.03) m, putting the object directly above the basket center. I estimate the distance from the staging pose at (0.22, -0.06, 1.05) m as 0.14 m. The final pose is closer to the base’s approximate x = 0.3 m, so it should be easier to reach. Tilting seems unnecessary here; keeping the downward orientation should avoid another slip. I plan to release over the red basket at end-effector z = 1.03 m, with an estimated drop of 0.1 m. A downward carry of the watch toward the white basket at (-0.32, 0.04, 1.03) m also seems straightforward, but its grasp needs a test lift first. After confirmation, I could transport both objects toward staging poses simultaneously. The left arm is currently at (-0.041, -0.081, 0.929) m. A direct target at (-0.32, 0.04, 1.04) m has an estimated distance of sqrt(0.279² + 0.121² + 0.111²) = 0.324 m, exceeding the 0.25 m limit. A staging target at (-0.20, -0.05, 1.04) m has a planned change of (-0.159, +0.031, +0.111) m and an estimated distance of 0.197 m. Could reach near the middle still be an issue? Moving outward to the left should be easier. The right arm is currently at (0.132, -0.09, 0.969) m. A staging target at (0.25, -0.04, 1.04) m has a planned change of (+0.118, +0.05, +0.071) m and an estimated distance of 0.146 m. Alternatively, a direct final target at (0.32, 0.04, 1.04) m is about 0.228 m away, within the 0.25 m limit and near the right base, so its precheck would likely pass. I could stage the left arm at (-0.20, -0.05, 1.02) m before its final move and use 15 control steps for transport. Before any watch transport, I must make a small lift and confirm that it moves with the gripper. I considered using three steps to lift the left arm toward z = 0.98 m while moving the already-tested right arm upward toward z = 1.04 m, perhaps at (0.20, -0.06, 1.04) m. That motion seems small and safe, but I will hold the right arm at its current measured pose with its gripper closed so I can clearly assess the watch’s test lift. I will use three control steps, keep the left orientation steady and its gripper closed, then inspect the watch.

The left gripper’s opening command is now 0, but the center watch remains on the table near high-camera pixel (299, 241). The grasp failed during the test lift. Did the watch slip immediately, or did the fingers close through the ring’s opening? In the left wrist view, the ring appears to surround the closed fingers rather than being held across its outer band. I suspect the fingers entered the hollow center, but the exact contact is uncertain. Before closure at observation 223, the open fingertips were at image x = 125 and 515 pixels, while the watch’s outer edges were at x = 244–433 pixels. Closing should have contacted those outer sides at an opening command around 0.3 rather than 0. At observation 226, the opening command was 0.327, and the fingers appeared near x = 235 and 405 pixels, possibly contacting the outer ring. Did the watch shift, or did the fingers squeeze a flexible band? During the lift, the command reached 0 and the fingers appeared inside the ring. Perhaps the contact height was too high: the fingertips may have been around z = 0.771 m and the band top around z = 0.79 m. The pads could have been above the band, allowing the fingers to slide over its top and close through the hollow center. The opening command is not a measured finger gap, so 0.327 did not establish contact; low friction is another possible explanation for the loss. The first watch grasp succeeded at end-effector z = 0.923 m, while this watch failed at z = 0.929 m, only 6 mm higher and with a different quaternion that introduced some tilt. I should try a lower regrasp around z = 0.91 m so the pads reach alongside the outer band. The watch appears to have a roughly circular band lying flat, with its face at the front-right. Closing across world X through the center could contact the band’s left and right outer sides if the pads are low enough. I could also aim across solid band segments rather than the hollow center. A lower grasp should help, though the failure mechanism remains uncertain. The green car remains secure, so the right arm can begin carrying it toward the red basket while I recover the watch. I initially considered 12 steps toward the right staging pose [0.25, -0.04, 1.04] m with the gripper pointing downward; its current orientation is slightly off that pose. The watch has shifted from high-camera pixel (302, 237) to approximately (299, 241), slightly down and left after the failed grasp. Assuming its height is z = 0.765 m, I estimate its new world position at x ≈ -0.046 m, y ≈ -0.102 m. The left end effector is currently at [-0.042, -0.083, 0.966] m. The watch center appears near wrist pixel (317, 259), beneath the fingers. I might have expected v ≈ 230 pixels at end-effector z = 0.966 m with a fully downward orientation, so the observed v = 259 pixels may reflect a Y offset. For the regrasp, I considered opening and lowering toward z = 0.91 m with x = -0.047 m and y = -0.10 m. An initial open-gripper target of [-0.047, -0.102, 0.93] m with a downward orientation could produce about 0.036 m of descent in three steps while opening. However, if the closed fingers are inside the ring, opening during descent could push the band outward or snag it. It is better to reopen at the current pose first, then descend separately. I considered two steps to open in place, or three steps holding the left pose while the right arm moves toward staging for eight steps. Since both arms share the action’s step count, I will use eight steps: hold the left arm at its current measured pose and command it open, while carrying the closed right gripper toward [0.25, -0.04, 1.04] m in the downward orientation. The right target is about 0.14 m away with only a small orientation change, so eight steps may be enough to approach it. I will inspect the result before descending for the watch regrasp.

The green car has dropped again despite keeping the gripper downward during translation. The right opening command is now 0, and the car appears on the table near high-camera pixel (427, 222), overlapping the red car. The opening command was 0.336 after the test lift, but reached 0 during the eight-step carry. Perhaps the grasp was not secure enough. At the test-lift end-effector height of 0.969 m, a rise of 0.036 m, the car appeared to lift, but could it still have been supported by the table? Could the fingers have slid along its body, or could contact with the table have contributed to its apparent rise? The green car now appears to have pushed the red car, leaving them adjacent. I need a more robust car grasp. Perhaps continued closure applies too much force and squeezes the smooth, tapered body out of the fingers. Would contact at the wheels or spoiler be better, or could I grasp across the front and rear? The green car has an elongated body with curved sides. I closed at end-effector z = 0.933 m, with estimated fingertips at z = 0.775 m, perhaps around the upper body. Did it slip upward through the pads, or did closure on the taper eject it downward? A lower grasp around the chassis or wheels may help. I considered end-effector z = 0.90 m, which would put the estimated tips at z = 0.742 m, slightly below the assumed table height of 0.75 m. Perhaps the actual finger extent is nearer 0.14 m, which would put them at z = 0.76 m instead. The first green-car grasp at z = 0.923 m lasted through 15 steps of tilted staging before slipping, whereas the second grasp at z = 0.933 m slipped sooner. Lowering by 0.02–0.03 m may improve contact. However, the first descent stalled at z = 0.923 m; was that object contact? Forcing a descent to z = 0.91 m might be feasible but could push the car. Another option is a grasp at z = 0.915 m with slower closure, followed by a 0.08 m verification lift. I should reopen fully before approaching. Closing along the car’s approximately 0.11 m long axis would exceed the estimated maximum gripper opening of 0.08 m, so grasping across its approximately 0.05 m width seems best. There are 863 control steps remaining after using 237. Two peppers and one watch are placed, making three completed objects and four remaining: two watches and two cars. I can take time to recover carefully. The touching cars need to be localized before another grasp. The green car appears diagonally oriented near high-camera pixel (427, 223), while the red car is near (416, 244), perhaps partly beneath it. In the right wrist view, the green car may be on top of the red car. Its side faces the camera and its wheels are visible; could it have rolled 90° onto its side after slipping? If it rests on the red car, lifting it could move both. I may need to grasp the green car, lift it clear, and place it while leaving the red car behind. Its placement orientation inside the basket does not matter, but the current body width may now be vertical, which could change the grasp direction. Using slightly different high-camera estimates, the green car is near (427, 224), diagonally toward the upper right, and the red car near (414, 245). The green car’s side profile and wheels appearing on top suggest it may have rolled onto its left side and be resting against the red car. A grasp at the green body’s center with fingers closing horizontally along world X might now contact its front and rear rather than its sides. I should choose the orientation from its current geometry. I also considered picking both cars together: both belong in the right basket, so transporting them as a cluster could satisfy the task. The cluster may be about 0.09 m wide, though, possibly too wide for the gripper. Separate grasps remain an option. The left watch also needs a lower regrasp. I can reopen the right gripper and move above the car cluster for a clearer wrist view at end-effector z = 1.03 m. The right end effector is currently at [0.226, -0.054, 1.023] m in the downward orientation, with opening command 0. The green car may be below it around world x = 0.24 m, y = -0.04 m. A possible observation pose is [0.24, -0.06, 1.03] m with the gripper open. I will focus on the left watch first while preparing to open and make a small adjustment with the right arm. At observation 237, the left gripper is already open, the watch center is near wrist pixel (317, 253), and the left end effector is at [-0.042, -0.083, 0.966] m with a slight orientation deviation. Before moving, I will use the image coordinates and recorded calibration to refine the watch’s world position at an assumed height of z = 0.765 m and estimate the green car’s position from the camera views.

The second watch is at approximately x = -0.045 m, y = -0.106 m. The left end effector is at x = -0.042 m, y = -0.083 m, giving an end-effector Y offset of +0.023 m relative to the watch. The watch is closer to the robot, so I should target y = -0.106 m. Assuming z = 0.775 m, the car cluster’s estimated center is at x = 0.225 m, y = -0.089 m. The right end effector is at x = 0.226 m, y = -0.054 m, giving a Y offset of +0.035 m. Both grippers need to move toward the robot, along negative Y, to center over the objects. The high-camera estimate of the green car’s X coordinate may be around 0.24 m; the wrist-image point at (317, 224) pixels may represent a particular point on the cluster rather than its center of mass, so this localization is approximate. I will align both grippers at a pre-grasp height of z = 1.0 m rather than 1.03 m to shorten the final descent. The left target is [-0.045, -0.106, 1.0] m and the right target is [0.225, -0.089, 1.0] m, both open and pointing downward. This raises the left end effector from z = 0.966 m by 0.034 m while changing Y by -0.023 m. It lowers the right end effector from z = 1.023 m by 0.023 m while changing Y by -0.035 m. Opening and lowering the right gripper before its Y correction could risk contact with the car, but at z = 1.0 m I estimate the fingertips at z = 0.842 m, above the car’s estimated top at z = 0.80 m, so the motion appears safe. I will use six control steps.

The clearer right wrist view shows both cars upright and touching, perhaps at the green car’s front-left corner. The green car’s center is around pixel (412, 120), or approximately (u = 411, v = 119), rather than the earlier point (317, 224). The red car’s center is around (290, 210), or approximately (u = 290, v = 209), closer to the gripper center. I misidentified the earlier cluster point at (317, 224): it was on the red car, not the green car. My target at x = 0.225 m, y = -0.089 m therefore aligned toward the red car. The right end effector is now at x = 0.225 m, y = -0.084 m. The red car may still be near its original world position of x = 0.21 m, y = -0.112 m, though it has moved slightly. The green car may be near x = 0.26 m, y = -0.04 m; it appears near high-camera pixel (440, 225). I can pick the red car first with a lower chassis grasp, then handle the green car separately. The red car has a long body and wide rear wings. I should grasp across the main body’s center and avoid the wheels. With the current downward orientation, the fingers close along world X, which might contact the side wheels and body. Its width including the wheels may be about 0.08 m, close to the gripper’s maximum opening. Rotating the closing direction perpendicular to the car’s long axis could reduce the width that the fingers must span. The red car runs diagonally from top-left to bottom-right in the wrist image. In the high view, its long axis may run from (405, 253) to (428, 231); its visible bounds are approximately x = 398–443 pixels and y = 231–257 pixels. In the wrist view, the rear wing is near (213, 143) and the front wing near (355, 286), giving an image vector of (+142, +143) pixels. Camera-right corresponds to positive world X. For points on the ground plane, increasing image v may correspond to decreasing world Y, toward the robot, although image height also depends on Z. I therefore estimate the car’s horizontal long-axis direction as positive X and negative Y, roughly (1, -1). Its perpendicular narrow direction would be (1, 1). For the downward quaternion, local Y, the closing direction, maps to world -X. Applying a yaw θ about world Z gives R = Rz(θ) R_down, with the closing axis (-cos θ, -sin θ, 0). To point along the normalized (1, 1) direction, I would need -cos θ = +0.707 and -sin θ = +0.707, so cos θ = -0.707 and sin θ = -0.707. That gives θ = -135°, or 225°. However, the opposite direction along the same closing line is equivalent. A +45° yaw gives the closing axis (-0.707, -0.707), along the same line as (1, 1). Its dot product with the estimated long axis (1, -1) is -0.707 + 0.707 = 0, so it is perpendicular. I will use a +45° yaw from the downward pose. Local X will still point down: Rz45 × (0, 0, -1) = (0, 0, -1). Local Z will become Rz45 × (0, 1, 0) = (-0.707, 0.707, 0). The wrist-camera view will rotate, but the object should remain visible. The desired quaternion is the composition Rz45 × q_down. The orientation change is about 0.785 rad, below the 1 rad command limit. This should allow a grasp across the red car’s narrow axis while reducing the wheel span. The green car’s wrist-image long axis runs approximately from (335, 30) to (510, 190), giving a vector of (+175, +160) pixels. That suggests a similar positive-X, negative-Y world direction. Both cars now appear diagonally aligned in the same direction after the drop, so the +45° downward yaw should suit both right-arm car grasps. The left gripper can retain its current downward orientation for the watch. I will use SciPy to calculate the yawed downward quaternion.

The downward quaternion with +45° yaw is [0.2706, -0.6533, 0.2706, 0.6533] in wxyz order. Its dot product with the original downward quaternion [0.5, -0.5, 0.5, 0.5] is 0.5 × 0.2706 + (-0.5) × (-0.6533) + 0.5 × 0.2706 + 0.5 × 0.6533 = 0.9239, giving an orientation change of about 0.785 rad. I can rotate the open right gripper at z = 1.03 m to avoid touching the car and center it over the red car, whose position is approximately x = 0.21 m, y = -0.112 m. The right end effector is currently at [0.225, -0.084, 1.003] m. I initially considered eight steps toward [0.212, -0.112, 1.03] m with the yawed downward orientation. The left end effector is at [-0.045, -0.106, 1.0] m, and the watch is centered at wrist-image coordinates (u = 320, v = 153) pixels. I want to descend toward z = 0.91 m in three stages for a lower band grasp. Both arms share the action’s step count, so I cannot give the right rotation eight steps while limiting the left descent to three. The left might reach z = 0.91 m in about six steps and then hold if the precheck passes, but eight steps near contact could be unsafe and would exceed the one-to-three-step guidance for the final approach. I will instead use three-step actions for both the left descent and right rotation, repeating as needed. For this short descent, I considered a left target at z = 0.915 m with the downward orientation, while retaining the right target [0.212, -0.112, 1.03] m with +45° yaw. The right arm should begin rotating and moving as the left descends about 0.03 m. I will inspect the observation after three steps.

Rotating the right gripper is changing the wrist-camera view. The red car’s long axis now appears nearly vertical, running from approximately (260, 60) to (380, 220) pixels, though it is still diagonal and the fingers currently appear diagonal in perspective. After completing the +45° yaw, should the car’s long axis appear vertical or horizontal? The gripper’s closing direction is always horizontal in the camera view because local Y maps to camera -X. If the car’s narrow axis aligns with local Y, its long axis should therefore project vertically. The left watch remains centered near (317, 199) pixels. I will continue the left gripper’s descent toward an end-effector height of z = 0.91 m and the right gripper’s yaw alignment for another three control steps, keeping both grippers open.

The right gripper’s rotation is progressing slowly, by about 0.11 rad over three control steps. I estimate it needs about seven more steps to reach the +45° yaw pose. The left end effector is near grasp height at z = 0.93 m. I will continue lowering it toward z = 0.91 m over the next three steps while the right gripper continues rotating. Could I close the left gripper at z = 0.91 m after two steps? At z = 0.93 m, the watch ring spans image x coordinates 216–415 pixels, with the open fingertips at x = 125 and 515 pixels. At z = 0.91 m, I expect its outer width to be about 230 pixels, which should still fit between the fingers. I will keep both grippers open and continue toward the same targets for three control steps.

The left descent has slowed again at an end-effector height of z = 0.923 m, and the quaternion has deviated slightly. It descended only 0.007 m in three steps without reaching the z = 0.91 m target. Could this be contact with the table, the fingers, or the watch? The current height is 6 mm lower than the failed grasp at z = 0.929 m, and the orientation is nearly downward, so it might be enough to grasp. I considered another two steps toward z = 0.915 m while the right arm continues rotating. The watch is centered near u = 318 pixels, with its outer ring spanning image x = 209–426 pixels, and the fingers are open. If the fingertips are already touching the table at z = 0.923 m, however, I need a different grasp location or orientation rather than further descent. A better option may be to pinch one side of the band, placing one finger inside the ring and the other outside. I could position the downward gripper over the left band segment, initially considering an end-effector X coordinate 0.02 m left of the watch center and the same Y coordinate as the watch. Closing along world X would then pinch that segment between the pads. The contact area would be small, but I expect this to hold the band more reliably than grasping across the entire hollow ring. The first watch’s outer grasp succeeded, but this one failed. For the band pinch, I will plan a left end-effector X coordinate 0.025 m left of the watch center, approximately x = -0.07 m, with y = -0.106 m. From the current x = -0.045 m, that requires moving left by 0.025 m. With an estimated open gap of 0.08 m and ring width of 0.05 m, I estimate the outer left finger at watch-center x minus 0.06 m, while the right finger would be approximately at the watch center, inside the hole. But shifting at the current height could cause contact. The right finger is now roughly 0.04 m right of the watch center; moving it left by 0.025 m would put it 0.015 m right of the center, requiring it to cross the right band. Its estimated fingertip height of z = 0.765 m may be around the band’s mid-height. I should lift to end-effector z = 0.98 m before shifting left and descending again. I estimate the lift and repositioning would take about six steps. Shifting along Y toward another band segment is also possible. Another alternative is to pinch the solid watch face protruding at the front-right. It appears as a white or silver disk near wrist-image coordinates (356, 332), with an estimated width of 0.025 m and height 0.01 m above the band. An end-effector offset of +0.015 m in X and -0.015 m in Y toward the face could let the fingers close across its sides, although one finger might also contact the band. The face is small and round, so I prefer the band pinch. I will first lift the open left gripper toward z = 0.98 m for three steps while the right arm continues its yaw alignment. Then I plan a three-step leftward repositioning toward x = -0.07 m at z = 0.98 m, followed by descent toward z = 0.915 m. The remaining black watch on the right could eventually use the same band-pinch approach. The right quaternion is currently approximately [0.377, -0.599, 0.377, 0.598] in wxyz order. After nine steps, is its yaw about 17°? The intended yaw is 45°, with the target quaternion’s w component approximately 0.2706. I estimate rotation of 0.11 rad per three steps, about 0.5 rad completed and 0.28 rad remaining. It may need another six to nine steps, which I can pair with the left arm’s three-step actions. For the immediate action, I will lift the left arm for three steps and continue rotating the right arm for the same three steps, keeping both grippers open.

The red car’s long axis is nearly vertical in the right wrist view, so the right gripper is nearly aligned for the intended grasp across its narrow body. I will move the left gripper over the watch’s left band segment for a band pinch, targeting (x = -0.07, y = -0.106, z = 0.98) m from its current position of (-0.046, -0.108, 0.953) m. I estimate the target distance as 0.034 m, within the motion limit. I will use three control steps to shift and lift the open left gripper while the open right gripper finishes rotating toward its target orientation.

The red car’s long axis appears vertical in the right wrist view, centered at approximately (u = 320, v = 130) pixels. The green car is to its right, and I see no collision. In the left wrist view, the watch center appears near u = 401 pixels, or about 402 pixels based on the ring’s span from 335 to 470 pixels. Its left band segment may be near u = 339–340 pixels, about 20 pixels to the right of the gripper center at u = 320 pixels. I want the left gripper centered over that band segment. The end effector is at x = -0.07 m, while the watch center is estimated at x = -0.045 m, an offset of +0.025 m. At an estimated depth of 0.17 m, that corresponds to 58 pixels, giving an expected ring center near u = 378 pixels. The observed center near 402 pixels may mean the depth is closer to 0.12 m. I initially wondered whether an end-effector target of x = -0.078 m would center the band, but the band appears to the right, so the correction should instead be rightward. If the band segment is at x = -0.065 m, its offset from the current end effector is +0.005 m, which I estimate would project near u = 345 pixels. Will it still appear near u = 345 pixels at a grasp depth of 0.08 m? The offset should increase as depth decreases; I estimate about +25 pixels. I will move the left end effector right by 0.005 m while descending, targeting [-0.065, -0.106, 0.915] m with the downward orientation. That should bring the band segment near u = 320 pixels. The right arm is ready for its descent. I considered lowering to z = 0.90 m, or using z = 0.905 m for a lower chassis grasp, which would put the fingertips near z = 0.747 m and might cause table contact. I will first use z = 0.915 m and assess the approach. With the +45° yaw, the fingers close across the red car’s narrow axis. From the current right end-effector height of 1.03 m, I expect three steps to lower it to about 0.997 m, with roughly four calls needed for the descent. The left descent from 0.979 m to 0.915 m may take about six steps. I will keep both grippers open, execute three steps toward z = 0.915 m for both arms, and inspect the result.

In the left wrist view, the watch’s left band is near x = 330 pixels, the watch center is at x = 415 pixels, and the gripper center is at x = 320 pixels. This looks suitable for the band pinch. The open left and right fingers are at x = 125 and 515 pixels. On closure, I expect the right finger to move left through the ring’s interior toward the band near x = 330 pixels. Is the outer left edge near x = 325 pixels? The band’s leftmost edge appears to be at 325 pixels, so the right finger should contact its inner edge near x = 340 pixels while the left finger moves right against its outer edge near x = 325 pixels, pinching the 15-pixel band segment. In the right wrist view, the red car’s narrow middle body spans x = 290–380 pixels, and its wheels span x = 280–390 pixels. The open fingers are at x = 125 and 515 pixels, leaving ample space. Lowering the right end effector toward z = 0.915 m should be fine. The left end effector is already low at z = 0.943 m. Over the next three control steps toward z = 0.915 m, it may reach z = 0.923 m and then stall again. Closing at z = 0.923 m might be sufficient for this band pinch because one finger will be inside the ring. I will continue both open-gripper descents for another three control steps.

Has the red car shifted in the wrist view? Its center now appears near u = 338 pixels, with the green car close to its right. The right finger near (515, 255) pixels appears to overlap the green car’s front-left body near (495, 270) pixels. The red car’s target world x coordinate is 0.212 m, perhaps matching its actual center, but the adjacent green car may obstruct the descent. In the right wrist view, the green car spans roughly x = 440–640 pixels, and the right finger near (515, 260) pixels appears to occlude its front. The gripper may already be contacting or pushing it, although the high-camera view suggests the green car is still near (438, 225) pixels. I need to avoid a collision. With the red-car grasp at +45° yaw, the open finger on the right extends toward the green car along the closing direction. Aligning across the red car’s narrow axis reduces the grasp width, but the fully open finger still occupies the green car’s space. I could move the green car away first, or grasp the red car with one finger in the gap and the other to its left. A narrower opening might help, but the boolean gripper command does not let me request an intermediate opening. I also considered approaching at -45° yaw, treating this as the same closing line with the fingers swapped, which would still leave a finger toward the green car. Another option is to shift the gripper slightly left so its right finger sits between the cars. Closure might then push the red car right into the green car. Both cars have the same destination, but I should still avoid unintended contact. Picking the rightmost green car first seems better. There is no obstacle to its right, and it is the car that needs a more reliable grasp. I can retain the +45° yaw, raise to a pre-grasp pose, shift right by about 0.05 m, and use a lower grasp across its narrow axis. Once it is placed, the red car will be isolated. Although I have already aligned for the red car, I should switch the order to create clearance. I could raise the right end effector from its current z = 0.963 m toward 1.03 m while moving over the green car’s center, tentatively around world x = 0.27 m, y = -0.06 m. I need to refine that position using the camera geometry. At observation 264, with the full +45° yaw, the green car’s center might be near (520, 170) pixels, or its body center near (500, 175) pixels, partly occluded by the finger. The red car’s center appears near (337, 210) pixels. I can invert the camera projection using an assumed object-center height of z = 0.775 m; the yaw means the wrist image’s coordinate mapping is rotated. The green car’s wrist-image bounds are approximately x = 440–640 pixels and y = 60–350 pixels, suggesting a center near (540, 205) pixels, though the right portion may be cut off. Its right edge may instead be near x = 620 pixels at y = 130 pixels, with a left edge at x = 440 pixels and center around x = 530 pixels. In the high view, its body appears near (440, 225) pixels. At z = 0.775 m, I tentatively estimate world x = 0.26 m, y = -0.068 m; another estimate is x = 0.258 m, y = -0.077 m. I will calculate positions from the high-camera candidates (440, 225) for the green car and (416, 244) for the red car, and compare them with wrist candidates. What world position would the green wrist point near (520, 180) pixels give at z = 0.775 m?

I estimate the green car’s world position at x = 0.25–0.264 m and y = -0.064 m, but the selected image points may represent different parts of the car. The high-camera point at x = 440 pixels may be toward its front, while the wrist point (520, 175) pixels may mark the hood rather than the whole body. A wrist body-center estimate around (520, 170) pixels gives x ≈ 0.241 m. The roughly 0.02 m discrepancy might mean the high-camera center should be at x = 432 pixels rather than 440. I considered examining enlarged crops of both views, but that may not be necessary. Another wrist-center estimate, around (515, 177) pixels, gives x ≈ 0.246 m. The red car’s estimated position is x = 0.2135 m, y = -0.106 m, close to its earlier estimate of x = 0.212 m, y = -0.112 m. For the green car after the drop, high-camera pixel (440, 225) gives x ≈ 0.264 m, but choosing (429, 224) as its center would give x ≈ 0.242 m. Its high-camera span appears to be x = 412–462 pixels, centered near 437 pixels; perspective may shift the apparent body center. I trust the wrist estimate more and will use a green-car grasp center of [0.25, -0.064] m with the 45° yaw. The right end effector is currently at [0.211, -0.111, 0.963] m. Its pre-grasp target will be [0.25, -0.064, 1.03] m, a planned change of [+0.039, +0.047, +0.067] m, with an estimated distance of 0.092 m. This should lift it safely away from the crowded grasp while repositioning over the green car, with the gripper open. The left fingers are ready for the watch-band pinch. I will close the left gripper and hold its current pose at z = 0.923 m for three control steps while the right arm begins its lift and repositioning for the same three steps. I will inspect the grasp afterward.

The watch lifted. I am unsure whether its high-camera position is still around (299, 242) pixels; it now appears beneath the gripper at (299, 238) pixels, compared with a possible previous table-level y coordinate of 244 pixels, suggesting a lift of about 6 pixels. The ring remains stable in the wrist view, with the fingers on its outer sides, and the opening command remains 0.355. I therefore consider the current grasp secure. I will carry the watch toward the white basket without tilting it to reduce the chance of slipping. The right arm has not yet reached its green-car pre-grasp target. Its measured position is (0.238, -0.082, 1.006) m, and the green car’s wrist-image center is at (u = 368, v = 159) pixels. Moving toward x = 0.25 m and y = -0.064 m should move the gripper right and back to center it. The red car now appears isolated on the left of the right wrist view. I will move the left arm toward a staging pose at (-0.22, -0.06, 1.04) m, keeping the watch in a downward grasp. The planned position change is (-0.154, +0.048, +0.082) m, with an estimated distance of 0.18 m. The left quaternion will be [0.5, -0.5, 0.5, 0.5] in wxyz order, with the gripper closed. The open right gripper will finish approaching (0.25, -0.064, 1.03) m while retaining its 45° yawed downward orientation. I considered three to six control steps and will use six; the left arm may only partially reach its staging pose in that time.

The green car is centered in the right wrist view at (u = 316, v = 153) pixels. Is the red car to its left clear of the fingers? It spans image x = 130–260 pixels, and the open left finger near (125, 255) pixels may overlap its front wing near (170, 240) pixels. Another estimate puts the wing near (200, 250) pixels. The left finger could collide with the red car during descent. The estimated world centers are (0.25, -0.064) m for the green car and (0.212, -0.112) m for the red car, so they are diagonally separated. Even with the narrow-axis grasp, open fingers extending approximately ±0.04 m could still touch the red car. I could shift the green-car grasp to the right, away from the red car, or approach with an offset that places one finger between the cars and the other outside. Pushing the green car is another possibility, but an offset grasp seems preferable. A rightward shift of 0.02 m might put the open left finger between the cars. The green car’s world x coordinate is about 0.25 m; in the wrist image, its body initially appears to span x = 250–380 pixels, while the left finger is at x = 125 pixels and occupies the gap near the red car. Shifting the gripper right by 0.025 m would move that finger away from the red car and put the other finger farther into empty space. On closure, the green car might center under the gripper or shift right, away from the red car. An offset of +0.015 m might also work. Placing a finger inside the wheelbase does not seem appropriate. The green car’s main body appears to span x = 245–385 pixels around u = 316 pixels. At a final end-effector height of z = 0.915 m, the left fingertip would project near (125, 275) pixels, while the red front wing may occupy x = 170–240 and y = 200–250 pixels, so contact remains possible. A rightward shift of 0.02 m might move the green car about 100 pixels left in the grasp view, putting its center near u = 220 pixels but still between the fingers. Since the camera and fingers move together, both cars would appear farther left, potentially clearing the red wing from the finger. However, closure with that offset could push the green car toward the red car. If the gripper center is right of the green car, the left finger is closer and would contact first, pushing the car left. Symmetric closure might push it left toward the center and possibly into the red car. Could I stop closure as soon as an offset grip forms? I can only influence partial closure through the number of steps while the opening command interpolates, so timing that would be difficult. Another option is to place the watch first, then use the left arm to pick the red car from the left while the right arm picks the green car from the right. That might separate them simultaneously, but the cars are close and the two arms could collide, so it is not ideal. The apparent overlap may instead be projection at different depths. I estimate the red front wing at z = 0.78 m and the fingertip at z = 0.872 m in the current pre-grasp pose. At end-effector z = 0.915 m, the tip would be near z = 0.757 m, but its world-Y path might pass in front of the red car. Earlier I switched away from the red-car grasp because its open finger appeared to overlap the green car, but actual contact might not have occurred. I will retain the centered green-car grasp and descend slowly while checking both cars’ positions. Three control steps may bring the right end effector to about z = 0.997 m, although its commanded target will remain z = 0.915 m. During those same three steps, the left arm will continue carrying the watch toward its staging pose.

At the right end-effector height of z = 0.999 m, the red car’s front wing appears to span x = 140–215 and y = 260–300 pixels in the right wrist view. The left finger is near (125, 260) pixels, so it is very close; could there be overlap near x = 125 pixels? Using the finger’s inner edge at x = 125 pixels and the wing’s left edge at x = 143 pixels gives a gap of 18 pixels. As I descend, the apparent sizes will grow, and the wing may contact the finger. The green car’s body center is near (u = 307, v = 180) pixels, which looks well aligned. I can descend for three steps and monitor the gap. Is the held watch already over the white basket near high-camera pixel (234, 207)? The white basket is visible at the top of the left wrist view, but the left end effector is at x = -0.197 m, y = -0.07 m, not yet over its center. The watch appears near high-camera pixel (236, 206), around the basket’s right edge. I could continue to the staging pose [-0.22, -0.06, 1.04] m and then move to [-0.32, 0.04, 1.04] m, or go directly to that final target. From the current pose [-0.197, -0.07, 1.025] m, I estimate the direct target distance as 0.164 m, within the command limit and likely reachable. This should place the watch over the white basket’s center. At the current end-effector height of 1.025 m, I estimate the watch’s bottom at 0.85 m, barely above the estimated rim height of 0.84 m; raising to 1.04 m should improve clearance. I considered six steps for the left arm’s final approach, but both arms share the step count, and three steps will allow partial progress while keeping the right descent cautious. I will target the left arm at [-0.32, 0.04, 1.04] m with its downward orientation and gripper closed, while the open right gripper continues toward z = 0.915 m. I will use three control steps.

The direct left-arm target appears too far forward to reach locally at z = 1.04 m with the gripper pointing downward. I could try a tilted carry or lower the end effector. Perhaps a target at (-0.32, 0.04, 1.0) m would be reachable, since lowering has helped before, but I estimate the watch’s bottom would then be at z = 0.82 m and might hit the rim. Tilting forward could place the watch about 0.1 m ahead of the end effector in Y. An end-effector pose at (-0.32, -0.06, 1.02) m could therefore put the watch near y = 0.04 m. This worked for the first watch, which I released from the tilted pose at (-0.279, -0.061, 1.049) m into the right side of the white basket. I could use a similar tilted pose at (-0.30, -0.06, 1.03) m for the second watch. For the immediate action, I will target (-0.30, -0.06, 1.04) m with the tilted wxyz quaternion [0.653281, -0.270598, 0.270598, 0.653281]. From the current left pose of (-0.197, -0.07, 1.025) m, the planned position change is (-0.103, +0.01, +0.015) m, with an orientation change of about 0.785 rad. I expect this to be locally reachable because y stays at -0.06 m, and the tilt should swing the watch forward over the white basket. I considered eight steps for the left-arm tilt while giving the right descent three steps, but both arms share the step count. With eight steps, the right arm might reach its z = 0.915 m target after about five steps and then hold near contact with the gripper open. That could be safe if there were no collisions, but the final approach calls for one to three steps. I will use three steps for both arms, keeping the left gripper closed and continuing the open right gripper toward its unchanged green-car grasp target. I expect the revised precheck to pass and can repeat short motions as needed.

The right descent stalled at z = 0.998 m, compared with 0.999 m previously, while X, Y, and orientation changed. This indicates contact preventing the descent. Initially I wondered whether the gripper was touching the red car or one of the baskets. In the right wrist view, the left finger is near (125, 260) pixels and the red car’s front wing spans approximately x = 123–208 and y = 275–311 pixels. Their overlap convinces me that the finger is catching the red wing. I should stop descending and lift away before changing the grasp. At +45° yaw, the closing line is approximately (-0.707, -0.707) in the horizontal world plane, with the open fingers extending toward both (-X, -Y) and (+X, +Y). I estimate the red car at (0.21, -0.112) m and the green car at (0.25, -0.064) m, giving a red-car offset of (-0.04, -0.048) m relative to the green car. That lies almost exactly along the negative closing direction. The cars are beside one another along their narrow axes, so an open gripper descending across the green car’s width puts a finger on the red car. I could lift and move right to attempt an offset grasp. I also considered exploiting the current contact by closing around the red wing and perhaps the green car, but that could catch both objects unpredictably. I still prefer to pick the green car first. Rotating the closing direction along its length would put the open fingers in front of and behind the car, clear of the red car. However, gripping the entire length may not fit: I have estimated its length at about 0.1 m, or perhaps 0.09 m against a maximum opening of about 0.09 m. A bumper-to-bumper grasp might just fit, but it is probably too long. A grasp on only a front or rear section is another possibility. Could I pinch the rear spoiler along the car’s length, even though the spoiler’s width runs across the narrow axis? I considered separating the cars by pushing before regrasping. A gentle +X or +Y push of about 0.03 m might move the green car away from the red car, although their contact geometry is uncertain and sliding could be unpredictable. The basket behind the green car may begin near y = +0.02 m, so pushing toward +Y could hit it. I tentatively estimate the red basket’s footprint as x = 0.2–0.44 m and y = 0–0.12 m. Moving the green car from (0.25, -0.064) m by +0.04 m in X to x = 0.29 m would keep it in front of the basket and farther from the red car; the right arm’s base is around x = 0.3 m, so that area should be accessible. I briefly considered placing a closed gripper 0.04 m to the right of the green car’s center, with the fingers down near z = 0.85 m, then moving it toward +X. But a pusher must be left of the object to push it right, and the red car occupies that side. From the right, that motion would require pulling instead. Pushing from the front toward +Y risks the basket, while pushing from behind toward -Y would require working in the tight space near the basket rim. Pushing the red car left would similarly require getting between the cars. These options are awkward. Closing at the current pose to lift the red wing first is also uncertain: the left finger contacts the red wing, while the right finger is near the green car and basket, so closure could push one car and grip the other. A grasp on a wing or spoiler looks more promising. Picking the red car across its narrow body would again put an open finger on the green car. Gripping its whole length would avoid that, but the Formula car is about 0.11 m long, compared with an estimated 0.08 m gap. Instead, I could pinch its rear wing from front and back along the car’s long axis. The wing is wide across the narrow axis but only about 0.01 m thick along the length. One finger in front of the wing and one behind it could provide a small but secure contact without entering the neighboring car’s space. I am not entirely sure which end is the rear in the high view; the red car has wings at both ends, and the large flat wing currently appears near v = 270 pixels in the wrist view. The same approach could work on the green sports car’s rear spoiler. Its black spoiler is at the top of the wrist image and spans the car’s width. Pinching its thickness along the car’s length would put the open fingers ahead of and behind the spoiler, rather than toward the red car. I should center the grasp on the spoiler midpoint, not the car’s body center. This offers a more distinct handle and may avoid the slipping seen with the body grasps. With the current +45° yaw, the car’s long axis appears vertical in the wrist image and the fingers close horizontally across its width. To close along its length, I need another 90° of yaw, choosing either +135° or -45°. The -45° downward quaternion is approximately [0.6533, -0.2706, 0.6533, 0.2706] in wxyz order. The +135° alternative is [-0.2706, -0.6533, -0.2706, 0.6533], equivalently [0.2706, 0.6533, 0.2706, -0.6533]. Either change from +45° is about 1.57 rad, exceeding the 1.0 rad limit for one action, so I need an intermediate orientation. I could go through zero yaw and then -45°, or through +90° and then +135°. I briefly considered [0, -0.707, 0, 0.707] as the zero-yaw quaternion, then recognized that zero yaw here means the original downward quaternion [0.5, -0.5, 0.5, 0.5]. I prefer the route through that downward pose to -45°. At -45°, local Y maps to approximately (-0.707, +0.707), which lies along the same line as the estimated car long axis (+X, -Y). The nominal +45° to zero-yaw change and zero-yaw to -45° change are each about 0.785 rad. I should lift the right gripper toward z = 1.05 m to clear the contact before completing this reorientation. The left arm can continue carrying the watch while the right arm changes approach. I need an estimated spoiler location. In observation 282, the green spoiler may be centered near (262, 116) pixels, with the black wing spanning approximately x = 215–325 and y = 80–140 pixels. The right end effector is at [0.253, -0.069, 0.998] m, and its orientation has deviated to roughly 40° yaw. Another visual estimate puts the body center near (290, 200) pixels and the spoiler near (270, 115). In the earlier aligned observation 276, I estimated the spoiler near (286, 83) and the body center near (316, 153), a vertical image difference of -70 pixels. At end-effector z = 1.03 m with the full +45° yaw, I tentatively place the spoiler about +0.03 m in world Y from the body and around z = 0.79 m. I could invert its projection either now or after lifting. The current high-camera spoiler estimate near (432, 213) pixels might correspond to x = 0.25 m, y = -0.04 m, z = 0.79 m, but that remains approximate. Using the body-center estimate (0.25, -0.064) m and the long-axis direction (+X, -Y) from rear to front, a rear offset of (-0.02, +0.02) m gives a spoiler center of (0.23, -0.044) m. The corresponding front estimate is (0.27, -0.084) m. I questioned whether the red car’s relative offset (-0.04, -0.048) m was truly along the narrow axis, but for a long axis of (+X, -Y), the narrow line is (+X, +Y) or (-X, -Y), so that offset is consistent with the red car being to the green car’s front-left side. The spoiler at (0.23, -0.044) m is farther from it. For a spoiler grasp closing along the long axis, I estimate the open fingers about ±0.04 m along that line around the spoiler. Possible finger positions are (0.198, -0.016) m at the back-left and (0.282, -0.072) m at the front-right over the hood. The back-left finger may be near the red basket’s front, which I should monitor. Relative to the red car at (0.21, -0.112) m, that finger has about 0.096 m of Y separation, which looks safe. I also need a suitable contact height. I initially considered fingers near z = 0.90 m, but the spoiler is around z = 0.80 m and the table around 0.75 m. An end-effector height near 0.928 m would put the fingertips around 0.77 m, allowing the pads to contact the wing near 0.80 m. I should avoid going so low that the fingers hit the body or table. A spoiler grasp around end-effector z = 0.93 m, perhaps 0.93–0.94 m, seems better than the 0.915 m target used for the lower body grasp. I estimate the vertical pad span as z = 0.77–0.83 m, with spoiler contact around 0.79 m. This should provide a more reliable pinch, and I could later use a similar rear-wing grasp for the red car. For the immediate recovery, I considered lifting the right arm to z = 1.06 m. I will instead target [0.23, -0.044, 1.05] m above the estimated spoiler while returning to the zero-yaw downward quaternion [0.5, -0.5, 0.5, 0.5], with the gripper open. From its current [0.253, -0.069, 0.998] m pose, I estimate the target distance at about 0.063 m and the orientation change at about 0.7 rad. Lifting should relieve the contact. I will use six control steps for both arms, keeping the left gripper closed as it continues toward [-0.3, -0.06, 1.04] m with the tilted quaternion beginning [0.653, …]. The right motion is upward away from the contact, so this longer recovery action appears safe.

The right gripper is still rotating, and the cars appear diagonal in its wrist view. I plan to reach a yaw of -45° by first completing the zero-yaw downward pose. The left watch is over the white basket but remains held. The left end effector has not yet reached its target x coordinate of -0.30 m, and its forward tilt is only partially complete. I can release the watch once it reaches that position and the full tilted orientation, but it is not ready yet. I will continue toward the same left target and the right zero-yaw target for six control steps.

The left watch is now directly over the white basket interior, so I can release it before completing the forward tilt. The left end effector is at (-0.296, -0.059, 1.042) m, with a partially tilted quaternion whose w component is 0.619. I tentatively estimate its local X direction in the environment frame as [0.15, 0.25, -0.95]. The watch may be offset by about +0.04 m in Y, putting its y coordinate near -0.02 m, still within the basket’s front half. In the wrist view, the white interior is behind the watch and the floor is near v = 400 pixels; the watch appears above the floor. Releasing it now should let it fall inside. The right gripper has not yet reached its zero-yaw downward orientation. I considered four or six steps for that rotation and will use four steps while opening the left gripper at its current pose. I also need to plan for the remaining black watch at approximately x = 0.283 m, y = -0.219 m on the right side of the table. After releasing this watch, the left arm could retreat and approach the black watch while the right arm grasps the green spoiler, but reaching that far right may be difficult. Letting the right arm handle the black watch after the cars seems easier for pickup. The left arm could otherwise handle the red car while the right handles the green car, but the red car at x = 0.21 m is far from the left arm’s current position near the white basket, so I do not favor that option. Transporting the black watch directly from the right side to the white basket may also be difficult. The right arm struggled to reach the middle basket, and the left basket is farther away. Could the left arm pick up the black watch directly? With the left base around x = -0.3 m and the watch near x = 0.28 m, y = -0.22 m, I estimate a reach distance of about 0.58 m, perhaps near or beyond its reach. The task may allow either arm to reach across the table, but the IK difficulties near the center make me uncertain. A tilted forward carry might let the right arm reach the left basket, although an end-effector pose near x = -0.28 m, y = -0.06 m would also be about 0.58 m from the right base and seems unlikely to be reachable. A handoff looks safest: after placing the cars, the right arm could pick up the black watch and transfer it to the left arm near x = 0 m, y = -0.2 m. I expect the left arm can reach that handoff point with some effort and then carry the watch to the white basket. I should keep the transfer clear of the middle basket and other objects. The left arm can prepare near the center after release, or attempt the direct pickup if it proves reachable. There are 806 control steps remaining, so I have room to handle this carefully. For now, I will release the left watch and continue the right rotation for four steps.

The second watch is inside the white basket. The right gripper is nearly at the zero-yaw downward orientation, [0.5, -0.5, 0.5, 0.5] in wxyz order. I initially considered finishing that rotation with three steps, then using eight steps to rotate to -45° yaw. However, I may be able to target -45° directly: the estimated change from the current yaw of about 8° to -45° is about 53°, or 0.925 rad, below the 1.0 rad limit. The desired wxyz quaternion is [0.653281, -0.270598, 0.653281, 0.270598], and the current quaternion is [0.468, -0.532, 0.461, 0.535]. My approximate dot-product calculation is 0.306 + 0.144 + 0.301 + 0.145 = 0.896, giving an orientation distance of about 0.904 rad, also below 1 rad. I will therefore target that orientation directly rather than finish the zero-yaw stage first. The position target above the spoiler is [0.23, -0.044, 1.05] m, close to the current measured position of [0.232, -0.046, 1.048] m. Ten steps may be enough to progress through this rotation. I will retreat the empty left arm from the basket and prepare it for a possible later handoff near x = 0 m, y = -0.2 m. I considered a downward staging pose at [-0.25, -0.25, 1.02] m, which would move it closer to the black watch while keeping it on the left. Another option is [-0.15, -0.25, 1.03] m. From the current position of [-0.296, -0.059, 1.042] m, that alternative has a planned change of [+0.146, -0.191, -0.012] m and an estimated distance of 0.24 m, within the 0.25 m position limit. I estimate the rotation from the current tilted quaternion, whose w component is 0.619, to the downward quaternion, whose w component is 0.5, at about 0.42 rad. The negative-Y motion retreats from the basket and appears safe; the second watch is already inside the basket, clear of this path. I will choose the nearer clear staging pose of [-0.20, -0.22, 1.04] m for the left arm, with an estimated position distance of 0.184 m. This leaves it near the center for a handoff. Both grippers will remain open. I will use ten control steps for both arms because the left retreat is high and appears unobstructed while the right gripper rotates above the spoiler.

In the right wrist view, the green car’s long axis appears roughly horizontal but diagonal, running from (370, 140) to (477, 205) pixels. The first point may be its rear and the second its front. The red car’s long axis appears more vertical and diagonal. I want to pinch the green spoiler along the car’s long axis. Would the -45° yaw target make that axis vertical? The +45° yaw made it appear vertical, and changing to -45° rotates the camera by 90°, so it should appear horizontal at the final orientation. The current intermediate orientation already shows it roughly horizontal. Since the gripper closes horizontally in the wrist image, that should align closure along the car’s length. The spoiler may be the black or gray wing running roughly vertically at the green car’s left, rear end near (295, 160) pixels. I currently estimate that end at (292, 168) pixels and the body center at (380, 170) pixels. The fingertips appear at x = 125 and 515 pixels, near y = 260 pixels. For the spoiler pinch, the gripper center needs to align with the spoiler so the fingers straddle its front and back horizontally. The gripper’s horizontal image center is u = 320 pixels; its relevant vertical coordinate is still uncertain. The end-effector target at x = 0.23 m, y = -0.044 m was chosen above the spoiler, which I expect to project near u = 320, v ≈ 140 pixels, or perhaps v = 135 pixels once the rotation finishes. The red car is below and to the left. Could the fingers near y = 260 pixels overlap its rear wing around (370, 280) pixels? The right finger at x = 515 pixels and the left finger at x = 125 pixels both appear clear. The left arm has not reached its staging pose yet, but it appears safe. I will continue both existing targets for eight control steps with both grippers open. I estimate that the right arm has about 0.6 rad of orientation change remaining and the left arm has about 0.1 m of position change remaining.

The right quaternion is close to its target, with its w component at 0.633 compared with 0.653. The green car’s long axis appears horizontal, and its rear spoiler is on the left near pixel (307, 156). The gripper’s horizontal image center is at 320 pixels, so the spoiler looks horizontally centered. A pre-grasp vertical coordinate of about 156 pixels seems plausible. The intended spoiler-pinch point is near pixel (320, 150). The red car is below the spoiler, spanning approximately x = 280–450 and y = 200–280 pixels. The fingers are near image y = 260 pixels, with the left finger at x = 125 and the right at x = 515 pixels. Their positions appear clear of the red car for the descent. I will descend toward an end-effector height of 0.93 m rather than 0.915 m to avoid the table and contact the spoiler near its estimated height of 0.79 m. The current end-effector height is 1.05 m; I expect three control steps to bring it to about 1.017 m. I could move the idle left arm to (−0.05, −0.22, 1.03) m to prepare for a later handoff. That might be reachable and save time later, but I will hold it steady during this precise right-arm approach. I will keep the left arm at its measured position of [−0.201, −0.219, 1.04] m with its downward orientation and gripper open, and use three steps toward the right-arm height target of 0.93 m.

The green spoiler is now centered near (323, 200) pixels in the right wrist view. What appears to be the red car’s front wing spans approximately x = 300–480 pixels and y = 225–303 pixels. The right finger is near (515, 260) pixels, perhaps 35 pixels to its right, while the left finger at x = 125 pixels appears clear. The right finger may contact the red car’s right front wing near x = 480 pixels as I descend. The 35-pixel gap may be sufficient, but I need to monitor it. The open fingers are at x = 125 and 515 pixels, and the green spoiler spans x = 310–330 pixels, giving it a suitably narrow horizontal thickness for the pinch. However, I am unsure about clearance from the green car’s body. The right finger at x = 515 pixels seems far past the body’s front near (540, 80) pixels; could it contact the hood? At grasp height, the fingers will be vertical, but will the green body be between them? I will inspect as the approach progresses. I will continue the descent for three control steps.

The right finger near pixel (515, 260) may now overlap the red car’s front-right wing near (500, 300). The black finger starts around (515, 256), and the wing’s right edge reaches about (515, 310), so there may be edge contact. The basket rim is a greater concern. The camera angle makes the red basket appear large on the left, and the left finger near (125, 255) may overlap its front wall. In the high-camera view, the right gripper’s fingers appear directly above that wall near image y = 175, while the cars are near y = 230. Descending over the spoiler near y = 225 could put the rear finger against the wall behind it, toward world +Y. At the current end-effector height of z = 0.994 m, I estimate the fingertips at z = 0.836 m and the rim at z = 0.84 m. There may already be slight contact, and a descent toward z = 0.93 m could hit the rim before reaching the spoiler. With the current −45° yaw, the open fingers lie along the car’s long axis, placing the rear finger behind the spoiler toward the basket. I could monitor another three steps, but this approach may stall against the rim. An alternative is to grasp the green car’s nose along its long axis, shifting the fingers toward the table and away from the basket. I estimate the front direction as (+X, −Y), though its projection is uncertain. In the high view, the basket’s front wall may be near y = 200 pixels, the spoiler near y = 214, and the car’s front near y = 240, perhaps around (453, 234). In the wrist view, the front is near (568, 160), up and right, while the spoiler is near (320, 240), down and left, with the basket wall behind and to the left. Moving the grasp toward the front could therefore clear both the wall and the red car below the spoiler. I could pinch the nose or front bumper along its thickness. The nose is low and tapered, however, so it might slip. Its thickness along the car’s length may be about 0.01 m at the tip. The spoiler still seems preferable if I can obtain basket clearance. I also considered pushing the green car forward along world −Y using closed fingers against the spoiler from behind. That would require lowering behind the spoiler near the basket, and the red car at the front-left might still make contact. Whether this would separate the cars remains uncertain. Picking the red car first may offer a clearer grasp. Its front-right wing is near the right finger, while its rear-left wing appears near (305, 280) pixels. I am not completely certain which visible wing is the rear; the larger white wing may be at the upper left. With the current −45° yaw, the red car’s long axis appears horizontal. A wing pinch could target the right end near (490, 310), which I identify as the front wing, or the left end near (310, 285), which I identify as the rear wing. The gripper is currently centered over the green spoiler near (320, 240), and the red rear wing is near (310, 290). Shifting down toward that rear wing could still put a finger into the green car behind and above it, with the fingers extending approximately ±0.04 m along the long axis. The red front wing near (500, 320) appears farther from both the green car and the basket. Pinching its thickness with one finger in front and one behind could provide a clear pickup, allowing me to place the red car first and leave the green car isolated. I will check this option by estimating the wing’s world position from the current wrist calibration. In observation 322, the white-and-red rectangular front wing appears centered near (492, 318) pixels; I will use an assumed height of z = 0.78 m. I also estimate the green spoiler near (330, 240) pixels. The script will compare the red front wing at (492, 318) and rear wing at (310, 282), both at z = 0.78 m, with the green spoiler at (329, 241), at z = 0.79 m.

The estimated world positions are (0.238, -0.135) m for the red front wing and (0.219, -0.055) m for the green spoiler, giving a Y separation of 0.08 m. The right end effector is currently at (0.23, -0.04, 0.994) m. I will move it to a pre-grasp pose at (0.238, -0.135, 1.0) m with the gripper open, retaining the -45° yaw orientation. This moves it 0.095 m toward the robot along Y and away from the basket, with a slight lift. I expect this motion to be safe and free of contact at z = 1.0 m. After alignment, I plan to descend to z = 0.93 m. The wing center should appear at u = 320 pixels once aligned, but its expected vertical image coordinate remains unclear. The green car is above and behind the red wing in the view. The open fingers extend approximately ±0.04 m along the car’s long axis, which I believe follows the horizontal line (+X, -Y) and its opposite. I initially estimate the rear finger’s distance toward the green car at about 0.08 m, with an open gap of 0.08 m. Centered over the red wing, the rear finger would be near (0.21, -0.107) m, while the green spoiler is near (0.219, -0.055) m, leaving an estimated gap of 0.052 m. That appears safe. The front finger would be near (0.266, -0.163) m in empty space. The red body extends behind the wing toward (0.20, -0.07) m, between the rear finger and the green car. The rear finger may contact the body near the wing attachment during the pinch, which seems acceptable. This looks like a promising grasp, so I will pick the red front wing. For the immediate action, I will reposition the open right gripper to (0.238, -0.135, 1.0) m without changing its intended orientation, use six control steps, and hold the left arm steady. Then I will inspect the new observation.

After six control steps, the right end effector has moved only -0.042 m along Y out of the intended -0.091 m displacement, so I can continue toward the same target. The red front wing is centered near wrist-image coordinates (u = 420, v = 250) pixels. I need to shift the gripper right in the image by moving the end effector toward the wing’s world position to center it. The right gripper’s orientation is aligned. I will continue toward the same target for six control steps and hold the left arm steady.

The red front wing is now centered near wrist-image coordinates (u = 320, v = 165) pixels, but the black watch appears near (550, 250), close to the right finger. I estimate the watch at world (x = 0.283, y = -0.219) m and the red wing at (0.238, -0.135) m, about 0.095 m apart. The open front finger extends along the car’s long axis toward +X and -Y, near (0.27, -0.16) m, leaving an estimated Y gap of 0.06 m to the watch. In the wrist view, the finger near (515, 260) pixels overlaps the watch’s apparent bounds of x = 490–590 and y = 200–300 pixels. Although the exact contact is uncertain, descending for the wing grasp would put that finger into the watch’s space. I should remove the black watch before continuing with the cars. It is visible in both the wrist and high-camera views, and the right arm is already nearby. The left arm is staged at [-0.201, -0.219, 1.04] m and could receive the watch near x = 0 m, y = -0.22 m. I initially considered having the right arm pick the watch at (0.283, -0.219) m and carry it to a handoff point near x = 0.08 m, y = -0.22 m. I could grasp across its outer band or pinch a band segment. Since the watch is circular, I could retain the current -45° yaw rather than rotate before pickup. A right pre-grasp target of [0.283, -0.219, 1.03] m differs from the current [0.238, -0.133, 1.0] m pose by [+0.045, -0.086, +0.03] m, an estimated distance of 0.102 m. That looks straightforward. I would then grasp at an end-effector height of 0.923 m and verify with a test lift. For a direct handoff, I considered carrying the watch to approximately [0.05, -0.22, 1.0] m while the open left gripper approaches [-0.05, -0.22, 1.0] m. That would leave only 0.1 m between the grippers. How should the watch sit between them? I would need to design that handoff carefully. Could the right arm carry the watch directly to the white basket? Given the earlier reach difficulties, I now think that cross-table reach is likely impossible, so transferring it to the left arm is preferable. The left gripper could pinch an exposed opposite side of the band or receive it from underneath, but a temporary table placement would be simpler and avoid the collision risks of a simultaneous handoff. The right arm can gently place the watch in clear central table space, release it, and retreat. The left arm can then grasp it and carry it to the white basket while the right arm resumes the cars. The area around x = 0 m, y = -0.22 m appears empty: the green car has moved from approximately (0.054, -0.172) m, and the second watch is no longer near (-0.04, -0.09) m. I could place the black watch at x = 0.02 m, y = -0.24 m. The left arm, currently near x = -0.20 m, should be able to grasp it around x = 0 m, y = -0.24 m. That may be near its reach limit, but the negative Y position is closer to the robot and should help. This adds steps, but it should provide a more reliable transfer and clear the red wing’s approach. For the immediate pickup approach, I will use the downward wxyz quaternion [0.5, -0.5, 0.5, 0.5] rather than retain -45° yaw, matching the orientation used for previous successful outer-band grasps. The rotation from -45° yaw is about 0.785 rad and can occur during the move to [0.283, -0.219, 1.03] m. Both grippers will remain open. The left arm could remain staged or move closer to the central transfer area, initially considering [-0.1, -0.24, 1.03] m. I will instead target [-0.08, -0.24, 1.03] m with the same downward orientation. From [-0.201, -0.219, 1.04] m, that is a planned change of [+0.121, -0.021, -0.01] m, which I estimate as 0.124 m. It should be reachable because y = -0.24 m is closer to the robot, and the right arm’s watch target near x = 0.28 m leaves ample separation. I will use eight control steps to approach the watch and prepare the left arm.

The right arm has not yet reached its target position or completed its rotation. The black watch’s center is at wrist-image coordinates (u = 392, v = 220) pixels. I will use six control steps to continue toward the right pre-grasp target at [0.283, -0.219, 1.03] m with the gripper open and pointing downward. I will hold the left arm steady at x = -0.1 m, y = -0.238 m.

The rotation from −45° yaw to the downward pose is progressing slowly. After 14 control steps, the right quaternion’s w component is still 0.564 rather than the target 0.5, and I estimate the remaining yaw at about −30°. Why is it so slow? The right arm may be near a joint limit, or the quaternion path may be contributing. Its position is nearly at the target, and the watch is centered at wrist-image coordinates (u = 320, v = 170) pixels. I could grasp at the current estimated −30° yaw because the watch is circular, or descend while finishing the rotation. However, I think the incomplete downward orientation gives local X a horizontal component, so the fingertips are not vertical. At the current end-effector height of z = 1.028 m, I tentatively estimate the finger direction as [0, 0.5, −0.866]. An angled approach might still pinch the band securely, so a fully downward pose may not be necessary. I could hold the current quaternion and lower to z = 0.93 m, but I estimate a horizontal fingertip offset of 0.08 m, meaning the actual fingertip x and y coordinates would differ from the end effector’s. The watch being centered at (320, 170) pixels establishes alignment in the camera view, while the fingertip projection remains fixed. At contact, the object needs to align with the finger line, not necessarily the end-effector x and y coordinates. Finishing the downward orientation first will reduce this uncertainty. I considered another eight steps toward the same target, which I expect might bring the quaternion’s w component to about 0.52, followed by perhaps four more steps. There are 752 control steps remaining. I will use one 12-step action toward the downward pre-grasp target, keeping both grippers open and holding the left arm steady. This remains a safe pre-grasp motion above the watch.

The right gripper is now aligned downward, and the black watch’s center appears at (u = 303, v = 153) pixels, slightly left of the wrist-image center. The right end effector is at x = 0.283 m, while the watch may actually be near x = 0.276 m. I will correct the end-effector X position by -0.006 m to a target of 0.277 m. Its Y position may already be accurate at -0.219 m. I will begin an open-gripper descent toward an end-effector height of z = 0.923 m for three control steps, while holding the left arm steady.

The watch’s center is still at u = 303 pixels in the right wrist view. The right end effector moved only 0.002 m toward its X target, apparently because the descent dominated the motion. I could try a larger correction toward x = 0.27 m. The 17-pixel offset at an estimated depth of 0.18 m corresponds to about 0.008 m. The current end-effector X coordinate is 0.281 m, and the watch is likely near x = 0.273 m, so I will use 0.273 m as the next X target and continue descending for three control steps.

The black watch’s center is now at u = 310 pixels in the right wrist view, which looks well aligned. I will continue the descent for three control steps, targeting the right end effector at x = 0.275 m and z = 0.923 m.

The black watch’s ring is centered at wrist-image coordinates (u = 318, v = 275) pixels, and the open fingers are outside the band. I will use two control steps for the final descent toward a right end-effector height of z = 0.923 m while holding the left arm steady. Then I plan to close the right gripper for three control steps.

The black watch is ready for grasping. I will close the right gripper around its band for three control steps while holding both arms steady.

I will make a three-step test lift of the black watch toward a right end-effector height of z = 0.975 m. I could move the left arm to a transfer pre-grasp pose around x = -0.03 m, y = -0.24 m, z = 1.03 m. Should I close it? No, I will keep it open. I could also move its x coordinate from -0.1 m to -0.05 m while the right arm lifts, but that is unnecessary now, so I will hold the left arm steady.

The black watch is secure after the lift check. I will transfer it to clear central table space for the left arm to pick up. Could the placement center be at x = 0 m, y = -0.25 m? Placing it at x = 0.02 m, y = -0.25 m should let the left arm reach it from its current horizontal position of (-0.1, -0.238) m. The right end effector is currently at [0.276, -0.22, 0.954] m. A direct target of [0.03, -0.25, 0.98] m has an estimated distance of 0.248 m, just within the 0.25 m limit, and raises it by 0.026 m. The precheck might fail near that distance and reach limit, so I will use an intermediate pose at [0.16, -0.25, 1.0] m, with an estimated distance of 0.125 m, before moving toward [0.03, -0.25, 0.96] m and lowering for placement. The cars are farther back near y = -0.1 m, leaving the path at y = -0.25 m clear. At an end-effector height of 1.0 m, I estimate the held watch’s bottom at z = 0.83 m, above the table. The left gripper is open at [-0.1, -0.238, 1.031] m. A right-arm intermediate target at x = 0.16 m leaves 0.26 m of separation, which appears safe. I considered preparing the left gripper at x = -0.02 m, y = -0.25 m, z = 1.03 m, but with the right arm at x = 0.03 m, their separation would be only 0.05 m and could cause a collision. I will keep the left arm at x = -0.1 m until the right arm has placed the watch and withdrawn. For the immediate action, I will hold the left arm steady and move the closed right gripper toward [0.15, -0.25, 1.0] m for 10 control steps.

The right arm is moving leftward more slowly than expected. Its current X coordinate is 0.177 m, so it has not reached the previous target of 0.15 m after 10 control steps, but it is making progress. I could next target the transfer pose at [0.06, -0.25, 1.0] m. From the current pose, that would change X by -0.117 m and Z by +0.01 m, with an estimated target distance of 0.118 m, which seems reachable. The left arm is at x = -0.1 m, giving 0.16 m of X separation if the right arm reaches x = 0.06 m. Each gripper may be about 0.08 m wide, so that may be adequate, although the held watch and the open left gripper at about z = 1.03 m would be close. I will hold the left arm stationary and withdraw the right arm after placement. I initially considered 10 steps toward [0.06, -0.25, 1.0] m, followed by lowering the right end effector to z = 0.924 m and releasing the watch. A target at x = 0.04 m would make the watch easier for the left arm to reach and leave 0.14 m of X separation, which still seems safe. I could instead target x = 0.03 m, though 10 steps might only bring the right arm to about x = 0.08 m. I will choose [0.03, -0.25, 1.0] m for 12 control steps, keeping the right gripper closed and the left arm stationary with its gripper open.

The right arm is now close to the left arm. In the high-camera view, the grippers appear adjacent but not touching, with the left open fingers near image x = 250 pixels and the right fingers near x = 320 pixels. The left arm’s measured position has changed from [-0.1, -0.238, 1.031] m to [-0.107, -0.235, 1.035] m despite being commanded to hold, and its quaternion has changed slightly. Could this drift indicate physical contact between the arms? The left elbow and right arm appear close. The grippers are about 0.144 m apart, with the fingers pointing downward; I estimate that their open finger extents along world X may leave a gap of about 0.06 m, which seems safe. I considered moving the left arm slightly away to x = -0.15 m before lowering the right arm. I will instead target the open left gripper at [-0.16, -0.24, 1.04] m, a small retreat of -0.053 m along X, while lowering the right end effector to z = 0.924 m with the watch held. Moving the left arm away should provide clearance for the descent. I will use three control steps for both arms. The intended watch placement is at x = 0.037 m, y = -0.247 m, where the table is clear. At an end-effector height of 0.924 m, I estimate the watch’s bottom will be at z = 0.75 m. After lowering it, I plan to release it and retreat the right arm.

I will continue lowering the right end effector toward z = 0.924 m for three control steps while holding the left arm steady at its current x coordinate of -0.149 m.

The right end effector is now at z = 0.933 m. Assuming the watch’s bottom was at the table height of z = 0.75 m when grasped at an end-effector height of 0.924 m, its bottom would now be at about z = 0.759 m, or 9 mm above the table. I will lower the right end effector toward z = 0.923 m for two more control steps before opening the gripper.

I will open the right gripper for three control steps while holding the left arm steady. After release, I may raise the right end effector to z = 0.98 m and then retreat toward [0.15, -0.15, 1.03] m. I considered combining release and lift in one five-step action, but moving toward z = 0.97 m before the fingers have fully opened could lift the watch again. I will instead open the right gripper while holding its pose for three steps, then retreat separately.

The watch is supported on the table. I will withdraw the right arm toward the cars and bring the left arm in to grasp it. I initially considered moving the open right gripper upward and rightward to [0.22, -0.14, 1.03] m, perhaps using a −45° yaw for the later red-wing grasp. The left pre-grasp target would be [0.036, -0.247, 1.03] m with the gripper open and pointing downward. From its current position of [-0.149, -0.24, 1.039] m, that is a planned change of [+0.185, -0.007, -0.009] m. It crosses the center, but the nearby Y position should make it reachable. However, the right gripper is currently at [0.036, -0.247, 0.924] m, directly below that target, so moving the left gripper there now could cause a collision. I need to clear the right arm first. I considered lifting the right gripper toward z = 0.99 m and shifting it +0.08 m in X toward [0.116, -0.247, 1.03] m over six control steps, while moving the left gripper partway to [-0.06, -0.247, 1.039] m. That would leave 0.176 m of separation. Once the right arm is clear, it could continue toward [0.22, -0.14, 1.03] m and the left arm could move to x = 0.036 m. I will stage these motions for safety. For the immediate action, I will instead target the open right gripper at [0.15, -0.20, 1.03] m, a planned change of [+0.114, +0.047, +0.106] m with an estimated distance of 0.162 m. The open left gripper will move to [-0.07, -0.247, 1.039] m, changing X by +0.079 m. Both will retain the downward orientation. They are near the center but will move apart: the right gripper starts open around the watch, so lifting appears safe, and the final X separation will be 0.22 m. I estimate the minimum separation along the paths may be about 0.1 m, which seems adequate. I will use six control steps.

The watch appears at pixel (340, 309) in the high-camera view and at (553, 148) in the left wrist view. It is about 0.1 m to the right of the left gripper: the left end effector is at x = -0.071 m, while the watch is near x = 0.036 m, a difference of 0.107 m. In the right wrist view, the watch is at (130, 260) pixels, close to the open gripper’s left finger at approximately (125, 260) pixels. The right gripper is moving rightward and upward away from it, which looks appropriate for clearing the pickup area. I will continue the right arm toward [0.2, -0.15, 1.03] m and move the left arm above the watch at [0.036, -0.247, 1.03] m. The planned separation is 0.164 m. I will wait to descend the left gripper until the right arm reaches x = 0.2 m. For now, I will keep both grippers open and use six control steps.

The watch is centered near (u = 385, v = 147) pixels in the left wrist view. The left end effector still needs about +0.03 m along X to reach its target at x = 0.036 m. The red car is visible at the upper right, and the black watch has been cleared from its approach area. The right end effector is currently at [0.172, -0.173, 1.017] m in the downward orientation. Has the red front wing moved? The red car appears near high-camera pixel (424, 241), similar to its earlier position, and the space toward the black watch’s former location is now empty. I will reuse the red front-wing pre-grasp target at [0.238, -0.135, 1.0] m with −45° yaw. The planned position change is [+0.066, +0.038, -0.017] m, with an orientation change of about 0.785 rad. I considered pairing three steps of right-arm rotation with a left-arm descent after finishing the left alignment. It is better to finish both pre-grasp alignments for eight control steps first, then descend both arms. I will keep both grippers open, target the left arm at [0.036, -0.247, 1.03] m in the downward orientation, and target the right arm above the red front wing at [0.238, -0.135, 1.0] m with −45° yaw.

The red car’s front wing is centered at pixel (320, 165) in the right wrist view. The green car is above it, and the black watch is now far from the right fingers at (u = 130, v = 480), toward the bottom-left, so the approach appears clear. The right gripper is only partly rotated. The red car’s long axis runs diagonally from pixel (120, 90) to (320, 170), rather than horizontally. Completing the −45° yaw orientation should make that axis horizontal for the wing pinch. I estimate another six control steps of rotation are needed, but I will split this into three-step actions while the left gripper descends toward the watch. For this action, I will target the left end-effector height at z = 0.923 m and keep the right end effector at its current position and z = 1.0 m while continuing its rotation. Both grippers will remain open. After three steps, I expect the left end-effector height to be about 0.997 m while the right gripper makes further rotational progress. I can then repeat the short approach as needed.

The right gripper’s orientation is close to its target, and the red car’s long axis appears almost horizontal. I will use another three control steps to finish the right gripper’s rotation while continuing the left gripper’s descent toward the watch.

The right gripper is fully aligned, and the red front wing is centered near pixel (315, 160) in the right wrist view. I will lower the right end effector toward z = 0.93 m to grasp the wing while continuing the left arm’s descent toward z = 0.923 m for the transferred watch. The right finger paths appear clear. The green car is above them, within image x = 0–360 and y = 0–100 pixels. The left finger is near (125, 260) pixels and the right finger near (515, 260) pixels, while the red wing spans x = 300–330 and y = 130–200 pixels. The black watch is near the bottom at (320, 480) pixels, away from the fingers. This looks safe for a short descent. I will keep both grippers open and descend both arms for three control steps.

The left gripper is ready to close at an end-effector height of z = 0.927 m, with the fingers on either side of the watch band. In the right wrist view, the red front wing is centered near pixel (315, 210), between the open fingers at approximately (125, 260) and (515, 260). I will use three control steps to close the left gripper while holding its pose and continue lowering the open right gripper toward z = 0.93 m. I expect the right end-effector height to move from 0.966 m to about 0.932 m during those steps.

The red front wing is centered near x = 330 pixels in the right wrist view and spans x = 300–350 pixels. The open fingers are at x = 125 and 515 pixels, positioned to pinch the wing’s thickness horizontally. At the right end-effector height of z = 0.936 m, the wing appears enlarged and spans y = 200–335 pixels, while the fingertips are near y = 260 pixels. I will close the right gripper so one finger contacts the wing’s left side near x = 300 pixels and the other its right side near x = 350 pixels. I will use three control steps to close on the wing while making a test lift of the left watch toward an end-effector height of z = 0.975 m.

The right gripper’s opening command is 0.52, higher than the approximately 0.34 reported for the previous body grasp. At first, I thought the wing was between the fingers near image x = 365 and 430 pixels. Looking more closely, it appears to span x = 360–430 pixels, with the right finger’s inner edge near x = 425 pixels. The black right finger near (430, 260) pixels seems to touch the wing’s right edge near x = 425 pixels, while the left finger near (180, 260) pixels appears to touch the nose or cockpit rather than the wing’s left edge at x = 360 pixels. Has the car shifted during closure, or is the grasp no longer centered on the wing? Before closure, the open fingers were at x = 125 and 515 pixels, and the wing spanned x = 300–350 pixels. My interpretation is that the right finger moved left toward the wing near x = 350 pixels, while the left finger moved right and encountered the nose near x = 180 pixels before reaching the wing’s left edge near x = 300 pixels. Although the wing was centered near x = 320 pixels, the car extended left to about x = 100 pixels. The resulting grasp may therefore span the nose and front wing along the car’s long axis, rather than pinching only the wing’s thickness. I estimate the nose-to-wing grip span at about 0.08 m; the opening command of 0.52 also seems consistent with a longer grip on a car roughly 0.09 m long. This could be a stable, antipodal hold, but I need a test lift to confirm it. The right end effector is currently at z = 0.938 m. I will target z = 0.99 m for a three-step vertical test lift, keeping its orientation steady and the gripper commanded closed. The left watch has already lifted by 0.037 m and appears secure: its opening command is 0.344, and the object has moved upward. I could hold the left arm still to focus on the car’s test, or begin transporting the verified watch toward the white basket at the same time. The left path should remain acceptable even if the right grasp fails, so I will move both arms for three steps. The left end effector is currently at [0.036, -0.248, 0.964] m. A staging target of [-0.15, -0.15, 1.03] m gives a planned displacement of [-0.186, +0.098, +0.066] m, which I estimate as 0.219 m. This appears safe above the table and moves toward the white basket while remaining in the foreground. I also considered [-0.20, -0.12, 1.04] m, but its estimated distance of 0.26 m exceeds the 0.25 m target limit. I will use [-0.15, -0.15, 1.03] m instead, keep the left gripper closed in its downward orientation, and pair that transport motion with the right car’s short test lift.

The red car remains on the table at high-camera pixel (425, 247), apparently unchanged. The right gripper’s opening command is 0.095, almost closed. Are the fingers now underneath or inside the car in the wrist view? The car slipped during the lift and is not held; the long-axis closure may have ejected it. The nose-and-wing grasp failed. I should offset the gripper toward the wing’s outer side so that both fingers pinch only the wing. Previously, I centered the wing at image x = 320 pixels, with the open fingers approximately ±195 pixels from the center. The nose was near x = 100 pixels and the left finger near x = 125 pixels. During closure, that finger encountered the nose around x = 100–150 pixels, producing a long grasp instead of a wing pinch. I want the open left finger between the body and wing, near x = 280 pixels rather than 125 pixels, with the other finger ahead of the wing. My initial estimate is to shift the gripper right by about 150 pixels, corresponding to roughly 0.04 m. In the original image coordinates, that would put the left finger near x = 275 pixels and the right finger near x = 665 pixels, outside the view. More specifically, a +155-pixel shift would put the gripper center at x = 475 pixels, the left finger at 280 pixels, and the right finger at 670 pixels. The left finger could then contact the wing’s left edge near x = 300 pixels after a short closure, while the right finger approaches its right edge near x = 350 pixels. The nose would remain outside the fingers. This suggests an end-effector offset of approximately 0.035–0.04 m along the car’s long axis toward the wing’s outer side, in the (+X, −Y) direction. I am not certain whether this is actually the front wing. The nose appears on the left and the wing on the right, whereas a Formula car’s front wing should be ahead of the nose at its front end. This may instead be the rear wing. Regardless of that label, the useful direction is clear in the image: move toward the wing’s outer side on the right, placing the left finger between the body and wing. With the downward gripper at −45° yaw, camera-right corresponds to world direction (+0.707, −0.707, 0). The camera’s local right axis is −local Y, and local Y maps to (−0.707, +0.707, 0), so camera-right is opposite the closing-axis direction. A 0.04 m shift along camera-right gives a horizontal displacement of (+0.028, −0.028) m. Starting from the estimated wing position (0.238, −0.135) m, that would put the gripper center at (0.266, −0.163) m. This area was near the black watch’s original position, but it is now empty. I need to check that offset against the finger geometry. The open left finger lies approximately 0.04 m along negative camera-right from the end effector, a displacement of (−0.028, +0.028) m. With the proposed center at (0.266, −0.163) m, that puts the left finger at the wing center, (0.238, −0.135) m, rather than between the wing and body. My first image-coordinate description mixed the shifted finger positions with the object’s new projection. If the camera moves right by the equivalent of 155 pixels, the objects move left by 155 pixels in the new image while the finger projections stay fixed. The wing moves from x = 320 to 165 pixels, and the left finger stays at x = 125 pixels, leaving it 40 pixels left of the wing. The nose moves from x = 100 to −55 pixels, outside the image, and the cockpit moves from x = 200 to 45 pixels. The left finger is therefore between the cockpit and wing, while the right finger remains far to the right at x = 515 pixels. The apparent discrepancy with the 0.04 m world offset may come from the approximate depth scaling. At a depth of 0.08 m and focal length of 397 pixels, a 0.04 m shift would produce about 198 pixels of image displacement rather than 155 pixels. An offset of approximately 0.031 m would instead put the left finger 0.009 m toward the body from the wing center. I will use a 0.03 m offset along camera-right, giving world components of approximately (+0.021, −0.021) m and a new gripper center of (0.259, −0.156) m. Depending on depth, the wing should appear about 80–150 pixels left of the image center, with the open left finger just behind it and the right finger ahead. This is analogous to the band-pinch approach. The right end effector is currently at (0.237, −0.136, 0.972) m, with the nearly closed gripper empty. I will reopen it and move to a pre-grasp pose at (0.259, −0.156, 1.0) m, retaining the same intended orientation. After that, I plan to descend to z = 0.936 m, close around the wing alone, and test the lift. I expect the offset to prevent another nose-and-wing grasp. The third watch remains secure in the left gripper. Its end effector is currently at (−0.007, −0.225, 0.979) m, and I will continue toward the existing staging target of (−0.15, −0.15, 1.03) m. I will use eight control steps for both arms, keeping the left gripper closed while opening and repositioning the right. The left path is high and appears clear. Raising the right gripper slightly to z = 1.0 m while shifting should avoid snagging the car.

The red wing is now at pixel (245, 160) in the right wrist view, with the gripper center at u = 320 pixels, giving a horizontal offset of −75 pixels. The fingers are at u = 125 and 515 pixels. The left finger is between the nose at u = 40 pixels and the wing at u = 245 pixels, while the right finger is outside the wing. This looks suitable for pinching the wing alone when I close the gripper. I will first descend toward a right end-effector height of z = 0.936 m for three control steps, keeping the gripper open. The left arm is holding the watch at (−0.118, −0.168, 1.018) m. I considered a tilted staging target of (−0.28, −0.06, 1.04) m toward the white basket, with an estimated position distance of 0.194 m and a rotation of about 0.785 rad from the downward pose to the tilted quaternion beginning with 0.653. This path appears safe and should move the watch forward and upward. For the immediate action, I will use the left target (−0.29, −0.06, 1.04) m with the tilted orientation and keep its gripper closed. I will execute three steps for both arms, tilting and carrying the watch while lowering the right gripper, then continue in short increments until the watch is over the white basket and the right arm is ready to grasp the wing.

The red wing is at approximately (220, 205) pixels in the right wrist view, with the fingers at x = 125 and 515 pixels. This looks suitable for the wing pinch. I will use another three control steps toward the right end-effector height target of z = 0.936 m, expecting it to reach that height, while continuing the left arm’s tilted carry toward the white basket.

In the right wrist view, the red wing is near (220, 250) pixels, and the left finger is near (125, 260) pixels. Is it touching the car body near the wheel at (100, 270) pixels? It now appears to overlap the body’s left edge, roughly x = 90–180 pixels. As I descended, the car expanded leftward in the image, leaving the finger over the rear wheel or body rather than between the body and wing. With the wing spanning roughly x = 200–250 pixels and the body extending left through x = 0–190 pixels, closing here could produce another nose-and-wing grasp or a collision. The previous 0.03 m offset is insufficient at grasp depth. I initially considered shifting another 0.02 m toward camera-right to place the left finger near image x = 180 pixels, between the body and wing. The wing is currently near x = 220 pixels and the body ends near x = 190 pixels, leaving a 30-pixel gap. A camera-right end-effector shift of 0.015 m, with world components approximately (+0.0106, -0.0106) m, might move the objects left by about 75 pixels. That would put the wing near x = 145 pixels and the body’s end near x = 115 pixels, with the finger at x = 125 pixels between them. This suggests an end-effector target of x = 0.270 m, y = -0.167 m, an additional (+0.011, -0.011) m shift. At the current end-effector height of z = 0.941 m, shifting sideways could push the wing or body because the finger already appears to overlap the body. I should lift to z = 1.0 m, adjust the offset, and then descend again. Closing now might lift the car by its nose and wing again and allow it to slip, so precise repositioning is preferable. For the immediate action, I will keep the right gripper open and target [0.272, -0.169, 1.0] m, shifting its horizontal coordinates by (+0.013, -0.013) m from [0.259, -0.156] m while raising it. I expect this iterative adjustment to succeed. I will use three control steps while the left arm continues toward its existing white-basket target with the watch held. After those steps, the right end effector may be near z = 0.972 m and x = 0.265 m; I will inspect before another three-step motion and the subsequent descent.

In the right wrist view, the red wing appears near pixel (195, 180), spanning approximately x = 170–225 pixels. The car body lies to the left, around x = 0–150 pixels. The left finger is at x = 125 pixels near y = 260 pixels, so it may still be close to a small part of the red car’s body. The body’s bottom appears near pixel (20, 260), perhaps at the nose; I am uncertain about that detail. The right end effector is currently at z = 0.972 m. The remaining shift toward the revised pre-grasp target may provide enough clearance. I expect another three control steps toward [0.272, -0.169, 1.0] m to bring the right arm to that pose. I will keep its gripper open while the left arm continues carrying the watch toward the white basket, using three steps for both arms.

In the right wrist view, the red wing appears at x = 180–210 pixels and y = 120–200 pixels, with the car body extending leftward to an edge near x = 160 pixels. The left finger is near (125, 260) pixels, possibly close to the small front of the nose near (100, 260). Could they overlap during the final approach? The wing is offset about −140 pixels from the image center, and the left finger is about 60 pixels left of it. The finger is still within the body’s projection at some image heights, although at the fingertip height of v = 260 pixels, the small nose spans approximately x = 20–100 pixels, leaving a 25-pixel gap to the finger. The rear wheel and body appear higher in the image, around v = 120–200 pixels, rather than at the finger contact projection near v = 275 pixels. However, the physical fingers extend downward in the image, so could part of their length contact the body at v = 200 pixels? The left finger’s black polygon spans roughly x = 0–130 pixels at the bottom and perhaps x = 100–130 pixels at v = 200. It may be close to the red nose near (100, 255). I should consider a little more offset. One alternative is another 0.01 m shift toward camera-right, but that might put the wing near x = 100 pixels, to the left of the finger at x = 125 pixels. That would leave the finger outside the wing rather than positioned for a pinch. Ideally, the wing would be just right of the left finger, with its center around x = 150–180 pixels and the nose left of x = 125 pixels. My current estimate puts the wing center at x = 190 pixels, 65 pixels right of the finger. During closure, the finger might encounter the body edge at x = 160 pixels before reaching the wing near x = 170 pixels, producing another long grasp. The body edge may be at a different image height or depth and therefore outside the contact region, but I am not sure. I want the left finger in the gap between the body and wing. With the body edge currently near x = 160 pixels and the wing starting near x = 170 pixels, that gap is only 10 pixels, and the finger at x = 125 pixels is not in it. A rightward shift equivalent to about 40 pixels would move the body edge to x = 120 pixels and the wing’s start to x = 130 pixels, placing the finger at x = 125 pixels between them. The wing center would then be near x = 150 pixels. Would that require an additional 0.01 m at a depth of 0.08 m? My estimate for 40 pixels is 0.008 m. A 0.008 m end-effector shift toward camera-right gives approximate world components of (+0.0057, −0.0057) m, suggesting a new horizontal target of [0.278, −0.175] m. At grasp height, I expect this to leave the left finger just behind the wing, with the body edge to its left. The right arm has reached the previous pre-grasp target at [0.272, −0.169] m but has not descended yet. Image positions and gaps may change during descent. At the current end-effector height of z = 0.999 m, I estimate a depth of 0.16 m, compared with about 0.09 m at grasp height, a ratio of roughly 1.8. The offsets might approximately double as the objects’ projections expand around the image center while the finger projection stays at x = 125 pixels. Could the body edge end up near x = 40 pixels or the wing center near x = 50 pixels? That is difficult to estimate. In observation 456, at end-effector z = 1.0 m, the wing was near x = 245 pixels and the body may have ended near x = 200 pixels. In observation 462, at the final approach, the wing was near x = 220 pixels and the body edge near x = 190 pixels. The wing moved only about 25 pixels rather than scaling dramatically as the camera height changed. Based on the images, an additional world-coordinate adjustment of about 0.006 m seems reasonable. I will make the small offset with the gripper open before descending. The left watch appears over the white basket interior, where two watches are visible, but the held third watch remains near the front rim. It may soon be ready for release, though I should not release it yet. The left end effector is currently at [−0.206, −0.111, 1.034] m, with a partially tilted quaternion whose w component is 0.611. In the high-camera view, the watch appears near (213, 188) pixels, on the white basket’s right side. Its bottom appears near y = 221 pixels, while the white front wall is near y = 210 pixels. Is the watch below the rim? In the wrist view, the held watch is near v = 330 pixels, the basket floor spans about v = 100–260 pixels, and the front wall’s bottom is near v = 265 pixels. The watch appears below the front wall in that image and could still be outside the basket, in front of it. I will continue farther left and back toward the horizontal target [−0.29, −0.06] m before releasing. For the next three control steps, I will keep the right gripper open and target [0.278, −0.175, 1.0] m, approximately holding its current height while applying the offset. The left arm will continue toward its existing target with the watch held.

In the right wrist view, I estimate the red wing’s center at x = 165 pixels and the car body’s edge at x = 140 pixels. Is the left finger at x = 125 pixels between that body edge and the wing near x = 150 pixels? On reconsideration, the body ends at x = 140 pixels, so the finger is still within its horizontal projection by 15 pixels. However, at v = 260 pixels, only the nose spans x = 20–100 pixels, leaving a 25-pixel gap to the finger. This likely provides enough clearance. I will descend toward a right end-effector height of z = 0.936 m in three-step increments, perhaps requiring two calls. The left end effector has not reached its final X target: it is at x = -0.224 m rather than -0.29 m. Nevertheless, the wrist view now appears to show the held watch over the white basket floor alongside the other watches, so release from the current pose is likely possible. In the high-camera view, I initially estimate the held watch near (178, 190) pixels on the basket’s left side, within the basket’s horizontal span of x = 130–255 pixels. Is it still near the front? The front rim is at y = 210 pixels and the watch center appears near y = 188 pixels, suggesting it is inside. The left wrist view is less clear: the held watch is near v = 320 pixels, the basket floor extends behind it to v = 350 pixels, the other watches are near v = 200 pixels, and the front wall’s bottom is near v = 350 pixels. Perspective makes that relationship uncertain. The high-camera view is more convincing, showing the black watch near (177, 186) pixels inside the white basket polygon. I can release the left watch while the right arm descends. I should account for the other watches: the existing two may be near x = 190 and 218 pixels at y = 186 pixels, while the held watch is near (176, 186) pixels. They are close, but all appear inside the basket. There is no orientation requirement for this container placement. I will hold the left arm at its current pose and open its gripper for three control steps while lowering the open right gripper for the same three steps.

The third watch is inside the white basket. I can retreat the empty left arm toward the safe staging pose at [-0.2, -0.22, 1.04] m with the gripper pointing downward while the right arm continues descending. In the right wrist view, the red wing is near x = 130 pixels and v = 190 pixels. The left finger is near (125, 260) pixels, nearly aligned with the wing’s left edge, and most of the car body is off the image to the left. Could the offset now be too far? The wing spans x = 110–165 pixels, while the fingers are at x = 125 and 515 pixels. The left finger already appears beneath or along the left side of the wing, with the right finger farther away, so a wing pinch seems likely. With the body mostly off the image to the left, I expect to avoid another grasp spanning the body and wing. I will use three control steps to continue the right arm’s descent toward an end-effector height of z = 0.936 m while the left arm begins its retreat. The left arm may only partially reach its staging pose in those three steps.

At the right end-effector height of z = 0.94 m, the red wing spans approximately x = 90–150 pixels and v = 220–290 pixels in the right wrist view. The left finger of that gripper is at (125, 260) pixels, directly beneath the wing, while its right finger is farther away at x = 515 pixels. Could the left finger push the wing rightward during closure? The wing is close to that finger and appears positioned for a pinch against the right finger. The car body is off the view to the left, with no nose in the grasp area, so this should isolate the wing. I will close the right gripper for three control steps while the empty left arm continues retreating.

The red car rotated during closure. In the wrist view, its long axis now appears diagonal, and the wing may be held across its width between fingertips near (200, 270) and (390, 290) pixels. The right gripper’s opening command is 0.192, which I interpret as a small gap consistent with pinching the wing’s thickness. In the high-camera view, the red car has moved to approximately (438, 255) pixels and appears vertically oriented, while the green car remains on the table near (435, 224) pixels. The exact contact is still uncertain. The wing appears between the fingers, perhaps with a red vertical plate along the left finger. Another estimate puts the right finger near (390, 260) pixels and the wing’s horizontal span at about x = 200–260 pixels. I think pinching the wing caused the car to yaw during closure, but I need a test lift to verify the hold. I will make a small lift toward a right end-effector height of z = 0.99 m while holding its orientation steady and keeping the gripper closed. The left arm can continue retreating toward its staging target. I will use three control steps.

The wing pinch failed again: the right fingers are fully closed, and the red car is back on the table. Perhaps the contact was only at the fingertips and provided too little friction. I need a different grasp strategy for the cars. I considered pushing them into the red basket because they are near its front edge, and the skill allows pushing. However, the basket walls may be about 0.1 m high, or the tray rim perhaps 0.08 m high, so the cars cannot simply slide over it from the table. Could the front opening be lower? That is unclear. Tipping the basket is undesirable. I could also try scooping beneath a front wing or the body, supporting the car on one finger and cradling it with the other, but closure has tended to eject the cars. Grasping the wheels seems more promising. I could pinch a single tire along its axle or grip a pair of tires across the lower chassis. My hypothesis is that the earlier body grasps contacted the smooth, tapered upper surface; lower contact at the wheels should be more stable. I have not successfully descended below about 0.94 m because of collisions or the table, although the initial green-car grasp at an end-effector height of 0.923 m held briefly before slipping during transport. I initially considered going lower to 0.89 m to grasp the wheels, but I need to account for fingertip clearance. With the supplied finger extent of 0.1576 m, an end-effector height of 0.90 m would put the fingertips at about 0.742 m, below the assumed table height of 0.75 m. That would not be possible without contact. Could the table actually be at 0.72 m? My object mapping has assumed 0.75 m, and the descent stalls at 0.923 m may have been object contact rather than table contact. If the table is at 0.75 m, fingertips at an end-effector height of 0.923 m would be around 0.765 m, and table contact would occur near an end-effector height of 0.9076 m. That suggests a minimum height around 0.908 m, with a target of 0.915 m feasible and 0.91 m just above the table. I may be able to avoid the object contact that stalled the earlier descent by adjusting X and Y. For the green-car grasp at 0.923 m, were the pads already near wheel mid-height? I estimate a wheel radius of 0.02 m, an axle height of z = 0.77 m, and a wheel top at z = 0.79 m. Fingertips around z = 0.765 m could put the lower pads near the wheel center. It may still have slipped because the grasp was centered along the body rather than at an axle, contacting the roof or side body instead of the tires. The fingers’ local Z thickness along the car’s length may be about 0.025 m, so the longitudinal contact position matters. I will aim across a front or rear pair of tires, with the closing direction across the car’s narrow axis and the grasp center on the axle line. That should put the pads against the tires’ outer sides and provide higher-friction contact. I still need clearance from the neighboring car. Could shifting toward one tire side help? The cars remain close, but the red car’s rotation may have made one wheel pair accessible. The red car now appears near high-camera pixel (448, 250), while the green car is near (435, 225). The red car’s long axis appears nearly vertical along image Y, which I interpret as approximately world Y; the green car remains diagonal. The red car is slightly farther toward the robot, and the black watch has been removed. A downward grasp with the fingers closing along world X therefore looks suitable for a red-car tire pair. Its nearest wheels, possibly the front pair, may be near pixel (447, 257), but I should inspect the wrist view after repositioning before selecting the axle. Using a red-car center near pixel (447, 250) and an assumed height of z = 0.775 m, I estimate its world position at x = 0.275 m, y = -0.145 m. The right end effector is currently at approximately [0.278, -0.176, 0.972] m with the −45° yaw orientation. It is nearly above the car but needs a different orientation. I will reopen the empty right gripper, move above the estimated center at [0.275, -0.145, 1.03] m, and rotate to the downward wxyz quaternion [0.5, -0.5, 0.5, 0.5]. I estimate this target to be about 0.06 m away with an orientation change of 0.785 rad. Then I can use the wrist view to choose the tire pair. I will use 10 control steps for this pre-grasp alignment while the open left arm finishes retreating to its existing staging target at [-0.2, -0.22, 1.04] m with the same downward quaternion. The task is not complete: 483 steps have been used and 617 remain. The three watches and two peppers are placed, leaving the two cars. I will explain the switch to tire contact and focus on verifying a robust grasp before transport.

The red car’s long axis appears vertical in the wrist image, and its wheels are clearly visible. The upper pair, perhaps the rear wheels, is near pixels (218, 72) and (299, 59), close to the green car. The lower pair, which I identify tentatively as the front wheels, is near (260, 188) and (333, 170) and appears clear of nearby objects. The front wing is near (300, 218). I can try grasping the lower wheel pair across the car’s width. The right gripper has not yet reached the downward orientation. Its current wxyz quaternion is [0.578, -0.406, 0.578, 0.408]; I estimate its yaw at about -30°, although I am unsure of the exact yaw. The car’s long axis nevertheless appears vertical in this view. Will it still appear vertical once the gripper is fully downward? I should finish the orientation and center over the lower wheel pair. The current right end-effector position is [0.274, -0.146, 1.028] m. I estimate the red front axle’s image center at (297, 179) pixels and the body center at (278, 128). The intended grasp target should be over the axle, approximately 0.03 m toward the robot from the car center along its long axis. Is the high-camera estimate of the car center still around x = 0.275 m, y = -0.145 m? The front axle may be near high-camera pixel (448, 251), perhaps corresponding to x = 0.275 m, y = -0.17 m, but these are tentative estimates. With the end effector at y = -0.146 m, the wheel-pair center appears near v = 179 pixels. For a fully downward pre-grasp centered over an axle at an assumed height of z = 0.77 m, I would expect approximately v = 140 pixels. The incomplete orientation may explain the difference, and the image center may change when the rotation finishes. I will use the current wrist-camera calibration to estimate the axle’s world position from a pixel near (297, 179), assuming z = 0.77 m. A wheel pair on the green car is also visible and may offer a similar grasp later.

The estimated front axle position is (x = 0.258, y = -0.158) m. The current right end effector is at x = 0.274 m, y = -0.146 m, an offset of (+0.016, +0.012) m from the axle. I will center it over the axle. With the downward orientation, the fingers close along world X. The red car’s long axis appears almost vertical in the high-camera image; its exact world direction is still uncertain, but the wheel pair appears to run across X. The open fingers are at image x coordinates 125 and 515 pixels, while the wheel pair is about 80 pixels wide in the pre-grasp view. There appears to be ample clearance, with the green car near the top of the image and away from the lower axle. I plan to descend to an end-effector height of z = 0.91 m for the tire grasp. I estimate the fingertips would then be at z = 0.752 m, leaving 0.002 m of table clearance, with the pads contacting the tire centers near z = 0.77 m. The earlier stall near z = 0.923 m may have been caused by fingers contacting the wheels. Centering across the axle should leave the open fingers outside them and allow the lower descent. The open gripper width may be about 0.08 m, compared with an estimated wheel-track width of 0.06 m. Closing should squeeze the tires and provide a robust hold. First, I will finish the downward orientation and align above the axle at z = 1.03 m for eight control steps, keeping the right gripper open. I will hold the left arm at its staging pose.

The red car’s lower wheel pair is now centered at image coordinates (286, 136) and (364, 144) pixels, with the axle center at (325, 140) pixels. This alignment looks good, and the open fingers are well clear of the tires. I will begin descending the right end effector toward z = 0.91 m for three control steps.

The red car’s tire centers appear at (280, 163) and (371, 167) pixels in the right wrist view, with the axle centered horizontally at about u = 325 pixels. The alignment looks good. I will continue descending for three control steps.

The red car’s tire centers appear at (269, 202) and (385, 209) pixels in the right wrist view, with the axle centered horizontally at u = 327 pixels. The open fingertips are at x = 125 and 515 pixels, at y = 255 pixels. The tires’ outer edges are at x = 252 and 402 pixels, leaving gaps of more than 100 pixels from the fingers, so the descent appears safe. I will continue descending for three control steps, expecting the right end-effector height to reach about z = 0.931 m, then use two more steps toward z = 0.91 m. For now, I will execute the three-step descent.

At the right end-effector height of z = 0.931 m, the red car’s front tire centers appear at (248, 264) and (410, 282) pixels in the wrist view, with outer edges at x = 229 and 429 pixels. The fingertips are at x = 125 and 515 pixels, at y = 260 pixels, leaving estimated gaps of 100 and 85 pixels. I will lower the right end effector by the remaining 0.021 m toward z = 0.91 m. Three control steps may bring it to z = 0.916 m or 0.91 m. I will continue the open-gripper descent for three steps.

The right end effector has stalled at z = 0.923 m, and its quaternion has deviated slightly, similar to the earlier possible body or table contact. In the wrist view, the tire centers are at approximately (235, 286) pixels on the left and (414, 306) pixels on the right, with the fingers at x = 125 and 515 pixels. The fingertips project at v = 275 pixels, while the tire centers are near v = 300 pixels. Are the fingertips aligned near the tops of the tires? Could the front-axle Y estimate be wrong by about 0.005 m? The orientation deviation suggests possible finger contact with the table at z = 0.923 m. Perhaps the actual finger extent is 0.17 m and the open fingers hit the table at this height. If 0.923 m is the minimum end-effector height, I cannot lower it to 0.91 m. With a 0.17 m extent, the fingertips might be at the table near z = 0.753 m. The tire centers are estimated at z = 0.77 m, so the pads should extend upward far enough to contact them. I will close across the tires at the current pose rather than force another descent. I estimate the outer wheel-track width at 0.06 m and the open finger gap at about 0.08 m. Three control steps of closure should bring the fingers against the tires, with an expected opening command of approximately 0.4.

In the right wrist view, the fingers are at x = 200 and 430 pixels. The left tire spans x = 215–255 pixels, and the right tire spans x = 390–430 pixels. The fingers appear to contact the outer tire sides precisely, so the alignment looks good. I will make a small 0.04 m test lift over three control steps to check the grasp.

The tire grasp appears to be holding after the small lift: the opening command remains at 0.356, and the car looks stable relative to the gripper in the wrist view. The high-camera view is less conclusive. The red car appears near pixel (445, 249), with the bottom of its front wing at y = 259 pixels, the same as before. Are its wheels still touching the table? The 0.032 m lift should move it upward by about 3 pixels in the image, but I do not see a clear vertical change. It may still be on the table despite being held. I will make another lift toward an end-effector height of 1.03 m, an additional 0.075 m, while shifting slightly right and toward the foreground to confirm clearance. The right target will be [0.30, -0.18, 1.03] m, with its orientation held steady and gripper closed, for six control steps. If the grasp is secure, this should lift the car clear of the table. Although this begins navigation, the initial test suggests that the object moves with the gripper. Moving along +X and -Y should take it away from the green car behind it. I will hold the left arm steady.

The red car is secure now: the opening command is stable, and the car moves with the gripper. In the high-camera view, its nose is near pixel (475, 244), visibly off the table and separate from the green car near (437, 225). The tire grasp appears to solve the slipping problem. I will carry it toward the red basket with the fingers pointing downward, holding it at the front axle. The right end effector is currently at (0.296, -0.179, 1.022) m, with a slight orientation deviation. The car bottom may be about -0.20 m relative to the end effector. Using the grasp estimate instead—the front tires at z = 0.77 m, the end effector at z = 0.923 m, and the car bottom at z = 0.75 m—gives a bottom offset of -0.173 m. With that offset, the bottom is at z = 0.849 m at the current end-effector height, just above the estimated rim at z = 0.84 m. I need to account for the car’s offset from the grasp when placing it near the basket center at x = 0.32 m, y = 0.04 m. The front axle was at (0.258, -0.158) m and the car center at approximately (0.26, -0.13) m, so the center is about +0.028 m along Y relative to the end effector. I estimate the front wing extending -0.04 m along Y and the rear extending +0.08 m. With the end effector at x = 0.32 m, y = 0.02 m, the car center would be at y = 0.048 m, the rear near y = 0.11 m, and the front wing near y = -0.02 m. That should fit an estimated basket interior spanning y = -0.02 to 0.13 m. A downward target at (0.32, 0.02, 1.04) m would put the car bottom at z = 0.867 m, above the rim. From the current pose, the planned displacement is (0.024, 0.199, 0.018) m, with an estimated distance of 0.201 m, within the 0.25 m limit. It is near the right base’s approximate x = 0.3 m, but is y = 0.02 m reachable at z = 1.04 m? The earlier left-arm target over the white basket at x = -0.32 m, y = 0.04 m, z = 1.04 m failed its local reach check, so a similarly high, forward target may fail here. I could stage at (0.32, -0.06, 1.04) m and then tilt forward to swing the car into the basket. The tire grasp may survive that tilt better than the body grasps, but I do not need to risk it. The car is about 0.12 m long, and tilting might swing its rear forward and upward and its front downward. I am unsure of the swept path, and it could hit the rim. A direct downward approach at z = 1.0 m and y = 0 m would instead put the bottom at z = 0.827 m, slightly below the rim, risking contact during the crossing. At y = -0.04 m, the car center would be at y = -0.012 m, the front wing near -0.08 m, and the rear near +0.05 m, leaving the front outside the basket on release. Another direct option is (0.32, 0, 1.02) m with the exact downward orientation. The car center would be at y = 0.028 m, the front wing near -0.02 m, and the rear near 0.09 m, which seems sufficiently inside. The planned displacement is (0.024, 0.179, -0.002) m, with an estimated distance of 0.181 m. The lower height may help reachability, but the estimated bottom at z = 0.847 m leaves only 0.007 m above the rim. Raising to z = 1.04 m would provide about 0.02 m of margin while making reach harder. I will use a high staging pose at (0.32, -0.06, 1.05) m first, then aim for (0.32, 0.02, 1.0) m, lowering slightly as the car moves over the interior. At the final height, the estimated bottom would be at z = 0.827 m, below the rim but inside the basket, with a 0.077 m drop to the estimated floor at z = 0.75 m on release. The lower final height should also help reachability. For the immediate staging motion, the planned displacement is (0.024, 0.119, 0.028) m, approximately 0.125 m. I expect eight control steps to reach it. The later forward-and-down change would be +0.08 m in Y and -0.05 m in Z, approximately 0.094 m, and may pass the precheck. I will keep the right gripper closed and downward, hold the left arm steady and open, and execute eight steps toward the staging pose.

The tire grasp remains secure. Is the red car’s front wing close to the green car in the right wrist view? The green car appears above and to the left, while the red car is moving forward away from it without contact. I will continue toward the staging pose for six control steps.

The red basket’s rim is visible at the top of the wrist view, and the car’s front end—or possibly its rear wing—points toward it. In the high-camera view, the red car’s body appears to be near pixel (474, 197), above the basket’s front edge, with the front wing over the rim. I will move the right end effector to [0.32, 0.02, 1.0] m while keeping the gripper pointing downward. This target lowers it by 0.044 m and moves it forward by 0.093 m. Will the car’s bottom maintain clearance during the crossing? At the current end-effector height of 1.044 m, I estimate the car’s bottom at z = 0.87 m and the rim at z = 0.84 m. At the target height of 1.0 m, I estimate the bottom at z = 0.827 m, which should be acceptable once the car crosses into the basket interior. I considered six control steps, but I will use five and monitor for rim contact.

The car appears to be over the red basket’s front rim, but I am unsure whether its rear wing is inside the basket or occluded by the front wall. The red wall fills the upper half of the wrist image. I estimate the rear wing at v = 215 pixels, appearing just below the wall’s bottom at v = 240 pixels. In the high-camera view, the car body appears near (477, 194) pixels, with its front partly hidden by the gripper and the basket’s front wall at y = 209 pixels. The car’s image center may be near y = 197 pixels, suggesting it is inside. The right end effector is currently at y = -0.027 m. I estimate the car center near y = 0 m and the rear wing near y = +0.08 m, inside the basket, while the front wing near y = -0.06 m may still be outside. I will continue toward the same target of y = 0.02 m and z = 1.0 m for five more control steps. The remaining forward movement to the end-effector Y target is 0.047 m.

The red car is now well over the red basket interior. The basket wall and floor fill the wrist view, and the car’s front wing is visible at pixel (470, 200) inside the basket in the high-camera view. At the current end-effector height of 1.002 m, I estimate the car’s bottom at 0.829 m and the basket floor at 0.75 m, giving a drop of about 0.08 m on release. Could the car be touching the front wall? The large red wall is behind it in the wrist view, but the car appears to be inside. I will hold both arm poses and open the right gripper for four control steps, then inspect the result. I considered preparing the left arm for the green car, but it cannot handle that pickup, so I will keep it stationary.

The red car is resting inside the red basket, leaving the green car on the table near high-camera pixel (439, 227). It is now isolated, so I can use a tire-pair grasp across either its front or rear axle. Its long axis appears diagonal, from the rear at approximately (423, 215) to the front at (457, 238), corresponding to the world direction (+X, −Y). Only a sliver of the green car is visible near v = 376 pixels in the current right wrist view. For the red car, the downward orientation worked because its long axis was approximately along world Y after rotation. For the diagonal green car, I will use the downward pose with +45° yaw, quaternion [0.270598, -0.653281, 0.270598, 0.653281] in wxyz order. This gives a closing axis of approximately (-0.707, -0.707), perpendicular to the car’s long axis. Earlier, this orientation made the green car’s long axis appear vertical in the wrist view, so its tire pair should appear horizontal. I could choose the front axle near the right, lower end or the rear axle near the left, upper end. An initial front-axle estimate near high-camera pixel (451, 233) suggests world x ≈ 0.27 m, y ≈ -0.105 m. Has the green car moved during the red-car pickup? Using its apparent center near (438, 228) and an assumed height of z = 0.775 m gives an estimated center at x = 0.261 m, y = -0.074 m. A front-axle estimate near (453, 236) suggests x ≈ 0.28 m, y ≈ -0.10 m, while the rear axle near (425, 218) suggests x ≈ 0.24 m, y ≈ -0.055 m. I can refine these estimates with the high camera and the next wrist view. I will choose the front axle because it is farther toward the robot and to the right, with better clearance from the basket’s front rim, which I estimate near y = -0.02 m. The tire pair near the headlights appears exposed, with no other objects around its outer sides. Its grasp center may be around (0.281, -0.103) m, and the black watch has been removed from this area. The open right gripper is currently at [0.32, 0.005, 1.002] m. I will move it to the pre-grasp target [0.28, -0.105, 1.03] m with +45° yaw for 10 control steps. The planned position change is [-0.04, -0.11, 0.028] m, with an estimated distance of 0.121 m and an orientation change of about 0.785 rad. This retreats from the red basket while rotating at a safe height. I will hold the left arm at its staging pose, then inspect the next observation to localize the tire pair precisely.

The green car’s long axis appears diagonal in the right wrist view, with its front near (305, 200) pixels and its rear near (130, 50) pixels. The wheels are barely visible as small gray features along the side. The front axle may be around (270, 165) pixels, near the hood or windshield, but I am uncertain about that location. I should finish aligning the right gripper’s position and its downward orientation with +45° yaw. Its measured Y coordinate is still -0.06 m, compared with the target of -0.105 m. I will continue toward the same pre-grasp target for eight control steps.

In the right wrist view, the green car’s front appears near (370, 145) pixels and its body center near (340, 60) pixels. Only its front half is visible. Is my end-effector target too far forward relative to the front axle? I aimed above that axle, but the view is centered on empty table below the car, with the car near the top, so the end-effector Y coordinate may be too negative. The object appears around v = 100 pixels rather than the expected 140 pixels, which is not a large discrepancy. The front axle might be near (358, 92) pixels, though I am uncertain. The tires are not visible from this top-down view, perhaps because the sports car’s body covers them. The front wheel pair’s sides may be near (300, 60) and (370, 60) pixels. I could choose an axle location around the front of the side pod, just behind the front hood at v = 75 pixels, or inspect an enlarged crop to clarify it. The car currently spans approximately x = 265–415 and y = 0–170 pixels in the right wrist image. I estimate the front bumper at (370, 165), the windshield at (360, 110), and the side windows at (300, 50) pixels. Is the front axle just ahead of the windshield, around v = 90 pixels? Based on the car’s geometry, it should be beneath the front hood between the windshield and bumper, perhaps around v = 125 pixels. The rear axle would be behind the windshield, near v = 0 pixels. The front axle center could therefore be around (345, 80) or (350, 100) pixels; its location remains uncertain. I should use the wrist-camera calibration to estimate world positions from these image points. With the current end-effector target at x = 0.28 m and y = -0.105 m, what world position would a front-axle candidate near (347, 110) pixels give if I assume z = 0.77 m? I will calculate that estimate and compare it with candidate positions for the front bumper and body center.

The estimated green front axle is at (0.277, -0.085) m, rather than the current gripper position of (0.28, -0.105) m. I was about 0.02 m too far forward along Y. I should move the end effector back by +0.02 m in Y to -0.085 m and adjust X by -0.003 m. At pre-grasp height, I expect this to center the axle near image v = 140 pixels. Then I can descend to an end-effector height of 0.923 m and close across the tires or body. The sports car’s tires are mostly beneath the fenders, but their outer treads are exposed on the sides, so closing across the narrow axis should allow tire contact at the axle. I need to check clearance from the red basket rim. Its wall appears on the right of the wrist image, spanning approximately x = 500–640 and y = 0–200 pixels. The open right finger is near (515, 255) pixels, below the wall, but it could approach the front rim during descent. With the +45° yaw, the fingers open along the narrow axis, with paired positive or negative X and Y components. I initially estimate the finger on the world +X, +Y side near (0.31, -0.055) m, close to the basket’s front-left corner at approximately (0.32, -0.02) m, which raises the possibility of rim contact as before. Using the corrected axle position of (0.277, -0.085) m and an estimated finger offset of (+0.028, +0.028) m instead places that finger near (0.305, -0.057) m. If the basket’s front rim is near y = -0.01 m, that leaves about 0.047 m of clearance, which seems safe. The red car is inside the basket and appears clear of this approach. I will move the open right gripper to [0.277, -0.085, 1.03] m for four control steps while retaining its +45° yawed downward orientation. I will hold the left arm steady, then descend after checking the alignment.

The green car’s front axle may be near (325, 90) pixels in the right wrist view. The front bumper appears at (337, 180) pixels, the windshield at (329, 135) pixels, and the side body extends upward. I estimate the axle center at about (325, 95) pixels, close to the gripper’s horizontal image center at u = 320 pixels. The fenders obscure the tire treads from above, but the outer sides appear near x = 290 and 365 pixels, at y = 80–120 pixels. The open fingers are well away from them. I expect the tires to become visible during descent. I will use three control steps to descend toward a right end-effector height of z = 0.923 m.

In the right wrist view, the green car’s front bumper appears near (350, 225) pixels, its windshield near (335, 170), and its front axle around (315, 120). Is the car slightly right of center? Its body center appears near (310, 100), which looks reasonably aligned. The side tires may be near (260, 60) and (365, 60). Around the front axle at image y = 120 pixels, the body’s outer sides appear at x = 275 and 365 pixels, close to the gripper center at u = 320 pixels. I could consider an X correction of -0.005 m: the current X target is 0.277 m, while the object may be near 0.272 m. The offset seems within a reasonable tolerance, so I will continue the descent for three control steps, expecting the right end-effector height to reach about z = 0.963 m.

The green car’s front axle may now be visible, though I am uncertain which wheels I am seeing. The large front hood obscures some details. The gray side wheels near (200, 45) and (320, 0) pixels may belong to the rear axle. The front tires may be the black strips partly hidden along the body sides near (260, 180) and (385, 160) pixels. A grasp across the front axle, centered around (320, 155) pixels, looks suitable. The open fingers are at image x = 125 and 515 pixels, near y = 260 pixels. The front bumper is near y = 280 pixels, so the fingertips are near the bumper while the tires, around v = 150 pixels, appear above them. The fingers extend toward the bottom of the image; perhaps the pads along their length can contact the tires at v = 150 pixels. The fingertip projection stays near v = 275 pixels, and I expect a contact point at table level to appear around that coordinate. At the current end-effector height of z = 0.963 m, where should an axle at z = 0.77 m project? If the end effector is centered over the axle in X and Y, I tentatively expect v ≈ 225 pixels. At the final end-effector height of 0.923 m, I estimate the axle would project near v = 300 pixels. Visually, the bumper is currently near v = 280 pixels and the axle near v = 160 pixels; I also estimate that the axle may move to about v = 250 pixels at the final approach. This appears suitable for contact, though these projection estimates remain uncertain. I will continue the descent for three control steps toward an end-effector height of about 0.93 m.

The right end effector unexpectedly moved +0.006 m along X and deviated in orientation, reaching z = 0.943 m rather than the target of 0.923 m. This suggests contact with either the red basket rim or the green car. In the wrist view, the right finger near (515, 255) pixels does not overlap the green front bumper near (390, 330) pixels. The basket’s front wall is to the right; its left edge may be near (560, 270) pixels, so contact with the finger is not visually certain. In the high-camera view, the green car may have moved from (439, 227) to (437, 230) pixels, suggesting a slight down-left push. The unexpected positive-X motion and orientation deviation make contact with the basket’s front wall the most likely explanation. I should stop descending. Could I close across the tires at the current height of 0.943 m? The front axle appears near (300, 190) or (320, 180) pixels, with possible tire centers at (255, 160) and (375, 150) pixels. The fingers are near x = 125 and 515 pixels at y = 260 pixels, and the bumper is near (320, 320) pixels. The tires appear above the fingertips, so closing now might grip the hood or body and slip again. I could move the green car away from the basket before grasping it, perhaps by pushing or pulling it toward the robot, or gripping the bumper or body and dragging it. A rear-axle grasp would not improve clearance because the rear is nearer the basket wall. The front axle is farther away, but the current open right finger extends toward world +X and +Y, into the basket rim. Changing the grasp yaw may avoid that obstruction. With the zero-yaw downward pose, the fingers would close along world X rather than exactly across the car’s narrow axis. At an axle center of (0.277, -0.085) m, I estimate the open fingers at X offsets of ±0.04 m with the same Y coordinate. The right finger would be near (0.317, -0.085) m. If the basket’s front rim is at y ≈ -0.03 m, that leaves about 0.055 m of clearance. With the current 45° yaw, the right finger has a +0.028 m Y offset, placing it near y = -0.057 m. The rim may extend to y = -0.07 m, which could explain the contact. Keeping both fingers at y = -0.085 m seems safer. The green car’s long axis still appears diagonal in the high view, although contact may have rotated it slightly. A world-X closing direction would be about 45° away from the ideal perpendicular direction. It might still hold the tire pair diagonally, perhaps contacting one front tire and one rear tire. A 90° yaw would instead put the open fingers along world Y, with one near y = -0.125 m toward the robot and the other near y = -0.045 m toward the basket. That could still put a finger against the wall, so I prefer the zero-yaw downward pose. Another option is to shift the entire grasp toward the robot to y = -0.105 m, my original target. That would put the gripper 0.02 m forward of the estimated axle at y = -0.085 m, perhaps contacting the front edges of the tires or the bumper and hood. At the earlier target of (0.28, -0.105) m, I estimated the axle at image v = 105 pixels and expected it to approach the fingers during descent. With 45° yaw, the open right finger would then be near y = -0.077 m rather than -0.057 m, an extra 0.02 m of clearance. I could lift slightly, shift -0.02 m along Y while retaining that yaw, and close at z = 0.923 m. I also considered a horizontal target of (0.263, -0.105) m, but I am uncertain whether that shift follows the car’s long axis appropriately. Moving forward changes the contact toward the bumper rather than keeping it centered on the axle, although the tires may tolerate a slightly forward grasp. The simplest approach is to retain the estimated axle center at (0.277, -0.085) m and rotate to the zero-yaw downward pose. I considered doing this at a pre-grasp height of 1.03 m before descending to 0.923 m. A body-center grasp across X at z = 0.915 m is another possibility, but the earlier downward body grasp slipped; targeting the axle should provide better contact. The requested horizontal position was (0.277, -0.085) m, while the measured position is (0.283, -0.087) m, with wxyz quaternion [0.286, -0.649, 0.266, 0.653]. I am unsure whether the orientation deviation is mainly yaw, but the positive-X displacement supports the basket-contact hypothesis. For the immediate recovery, I will keep the right gripper open, lift toward z = 1.0 m over the axle at (0.277, -0.085) m, and rotate to wxyz quaternion [0.5, -0.5, 0.5, 0.5]. I will use eight control steps and hold the left arm steady. After inspecting the result, I can descend again. There are 516 control steps remaining, enough to proceed carefully.

The green car now appears clear of contact. I initially identify the front tires as small black or gray features near (300, 175) and (373, 163) pixels in the right wrist view, but I am uncertain. On reconsideration, the hood and windshield region appears near (320, 185) pixels, and the front axle should be behind the windshield, near the gray triangular features at (285, 130) and (360, 115) pixels. I will finish rotating the right gripper into the downward orientation over eight control steps, targeting an end-effector height of z = 1.0 m.

The right gripper’s orientation appears to have overshot slightly to about +3° yaw, but it is sufficiently downward. The green car’s long axis is diagonal in the wrist view, and I need to identify the front tire pair before choosing the grasp point. The gripper now closes along world X, which appears horizontal in the wrist image. Could the gray triangular side pieces near (192, 119) pixels on the left and (284, 42) pixels on the right be the front wheels, with the axle centered around (260, 110) pixels along the car’s narrow direction, perpendicular to its long axis? I also considered features near (300, 170) and (360, 140) pixels as front tires, but those appear to be headlights instead. I should use the car’s shape to distinguish the wheels. This sports-car model has four tires at its corners. The gray triangles near (175, 102) and (263, 15) pixels, close to the engine, may be the rear tires. The front tires could be just ahead of the side windows, near (236, 195) pixels on the left and (348, 100) pixels on the right, alongside black intakes near (216, 176) and (320, 85) pixels. Alternatively, could the gray triangles near (192, 128) and (282, 54) pixels be the front wheels? Interpreting this as a Lamborghini top view, I see the gray rear spoiler on the left, the rear windshield or engine beneath gray slats immediately to its right, a black cabin center around (280, 90) pixels, a black front windshield around (320, 170) pixels, and the hood to the right. The front axle may lie between the cabin and front bumper, around the black side intakes near (228, 155) pixels on the left and (352, 75) pixels on the right. The silver or gray triangular features near (192, 130) and (285, 42) pixels are more likely rear wheels behind the cabin. My current hypothesis is that the front wheels are dark and blend into the black intakes near (226, 190) and (360, 104) pixels. I want to grasp across those tires. Their estimated axle center is (293, 147) pixels, near the windshield’s left edge, rather than at the gripper’s horizontal image center of u = 320 pixels. I will use the current wrist-camera calibration to estimate the world position of a front-axle candidate at (293, 145) pixels, assuming z = 0.77 m. I will calculate that position before adjusting the grasp.

The estimated front axle position, (0.2675, -0.0774) m, is close to the right end effector’s current horizontal position of (0.278, -0.085) m. Aligning directly over it would require a 0.0105 m shift left and a 0.0076 m shift back. The gripper is nearly downward but has slightly overshot the orientation, so I will target the exact downward wxyz quaternion [0.5, -0.5, 0.5, 0.5] at a pre-grasp height of z = 1.0 m. With that direct axle alignment, I estimate the open right finger at world x = 0.3075 m, using a +0.04 m X offset, and y ≈ -0.077 m. The red basket’s front-left rim may be near y = -0.06 m, so contact is still possible, though less likely than with the 45° yaw. I will instead target [0.267, -0.087, 1.0] m, about 0.01 m forward of the computed axle position, to keep the open finger on the table side of the rim. That offset seems acceptable for contacting the front part of the tires. I will use four control steps to align the open gripper before descending.

The green car’s front axle may now be centered near (u = 320, v = 130) pixels in the right wrist view, which looks suitable. Only a small part of the red basket wall is visible at the top right, and the right finger appears clear of it, so the descent looks safe. I will use three control steps to descend toward a right end-effector height of z = 0.923 m.

The green car’s front axle is likely near (310, 180) pixels in the right wrist view, perhaps near the windshield. The open fingers are well away from it. I will continue descending for three control steps toward a right end-effector height of about z = 0.93 m.

At the right end-effector height of z = 0.93 m, the green car’s front axle area may be centered near (280, 220) pixels in the wrist view. Has the car shifted left of the gripper’s image center at u = 320 pixels? The front bumper appears near (400, 340) pixels, with the rear off to the left. The gray triangular features near (115, 220) on the left and (230, 70) on the right might be wheels, but they may belong to the rear axle. Another possible front-tire pair is near (200, 285) and (350, 170) pixels, with an estimated average of (275, 227) pixels. That would put the gripper center 45 pixels to the right. The left finger at approximately (125, 255) pixels is near a side intake or tire at (150, 270), while the right finger at u = 515 pixels is farther away. Closing here might grip the diagonal car across its side body, perhaps securely, but I should clarify the tire alignment first. The gray triangular pieces near (113, 234) and (218, 89) pixels are likely rear tires because they appear behind the engine, though I am uncertain. The actual front tires may be the dark side panels near (224, 322) and (383, 198) pixels. Their estimated average is (303, 260), close to the gripper center at u = 320 pixels and the fingertip level at v = 260 pixels. This interpretation gives a suitable front-axle alignment at z = 0.93 m. The open fingers are at u = 125 and 515 pixels, and the tire outer edges may be near u = 200 and 410 pixels, leaving clearance on both sides. I could close at the current height of 0.93 m or lower to 0.923 m. The red car was grasped at 0.923 m, so I will use two control steps to lower toward that height before closing. The gripper is pointing downward, its measured orientation matches the intended pose, and I see no current collision.

The descent has stalled at a right end-effector height of z = 0.929 m, with a slight quaternion deviation, likely because of contact with the car or table. I will close at this height. It is 6 mm higher than the red car’s grasp height, but the sports car has taller tires and body. In the right wrist view, the gripper’s left finger is near (125, 260) pixels, close to the green body’s left side at (125, 280) pixels. The right finger is at x = 515 pixels, farther from the body’s right edge near (500, 250) pixels. Closure should grip across the car’s width near the front axle. I tentatively expect an opening command of about 0.35. I will hold the poses and close the right gripper for three control steps.

The right gripper’s opening command is 0.586, which is relatively large. In the wrist view, the fingers are at x = 170 and 480 pixels and appear to contact the green car’s wide front body sides rather than the narrower tire track. I interpret the opening command as suggesting a body width of about 0.065 m; the tire track is similar, at about 0.06 m. The contact may be on the front side panels, tires, or fenders, so this lower grasp could still hold, but I am uncertain. I will make a test lift over three control steps toward a right end-effector height of z = 0.98 m. If the car slips, I will need to reposition the fingers onto the actual tires.

The right gripper’s opening command has dropped to 0.179 but has not reached 0. Is the green car still held between the fingertips? In the wrist view, the car has moved upward relative to the gripper. The fingertips appear near (270, 260) and (370, 260) pixels, touching the front bumper’s corners. The bumper is near (335, 260) pixels, between the fingertips, with the rest of the body above it. However, the high-camera position remains near (435, 227) pixels, and the car still appears to be on the table. The fingers may be underneath the bumper rather than securely holding it. I interpret the opening command of 0.179 as a small gap at the nose: the car seems to have slid until the fingers pinch its front bumper or nose. This could now be a stable antipodal hold, or it could still be slipping. I will make another small lift of approximately 0.03 m toward a right end-effector height of z = 1.0 m, keeping the gripper commanded closed. If the opening command stays at 0.179 and the car moves with the gripper, that would support a secure hold; if it reaches 0, I will treat the grasp as failed. I will use three control steps without changing the right arm’s X or Y position or its orientation.

The latest lift failed, and I think I mislocalized the green car’s axle. The red car’s front tires were easy to identify as black circles on its sides, whereas the green sports car’s wheels may be obscured from above. An angled wrist view could help reveal them. I considered rolling the car onto its side to expose a wheel or make a grasp across its top and bottom easier. Its orientation inside the container would not matter, but deliberately rolling it seems unnecessary. An offset pinch on the rear spoiler is another option. My earlier spoiler approach stopped because of the rim before I actually closed on it. Now that the red car is off the table and the green car is isolated, I can move the green car away from the basket first. A body grasp that cannot sustain a lift may still be sufficient to drag it along the table. The initial body grasp held through about a 0.03 m lift before slipping during translation. I could close around the front body and move slowly toward negative Y while staying low. Even if the grasp slips, friction might slide the car toward the robot. Once it is near y = -0.22 m, clear of the basket, I can attempt a properly aligned tire or spoiler grasp. The empty right gripper is currently closed at approximately (0.267, -0.089, 0.998) m, and I estimate the green car’s table position near (0.27, -0.08) m. I could reopen, lower around the body, close, and drag toward y = -0.20 m at an end-effector height of z = 0.94 m rather than lifting. Another possibility is to place the closed gripper behind the car, between it and the basket, at y = -0.03 m and z = 0.90 m, then push toward y = -0.18 m. That approach is tight against the rim. Placing the closed gripper in front of the bumper at y = -0.12 m and z = 0.90 m would not necessarily pull the car when moving farther toward negative Y; I would need to hook behind the bumper or close around the nose. Dragging with a body grasp seems easiest. I also considered using the left arm to tilt the car or hold the basket. It is idle near x = -0.2 m and would need to move over. A two-arm lift might now be worth considering, although the skill discourages using both arms on one object unless necessary, and coordinating that lift would be difficult. I prefer to try dragging first. There are 479 control steps remaining, so I still have room for a careful recovery. After moving the car, I should target the visible wheel pair rather than the hood. My front-axle target may have been about 0.03 m too far forward along the car’s length; moving toward the spoiler may reach the tires instead of the body. The gray triangular side features look like silver hubs with gray covers and may be the exposed tire tops. In observation 621, I tentatively locate them near (212, 130) pixels on the left and (286, 48) pixels on the right, with an average near (249, 89) pixels. The car has shifted in the view after the failed grasp, so these identifications remain uncertain. In the earlier +45° yaw view at observation 575, similar features may have been near (290, 50) and (360, -20) pixels; I targeted the front hood instead. In the current downward view, another estimate puts the visible pair at (205, 130) and (285, 50) pixels. Their image displacement is (+80, -80) pixels, toward camera-right and upward. I think that line is perpendicular to the car’s long axis, although I have not established the long-axis components clearly. Another possible pair lies near (150, 65) and (230, -15) pixels toward the rear. The pair beside the engine or cabin appears accessible regardless of whether it is the front or rear axle. A downward grasp with +45° yaw should rotate its narrow-axis line horizontally in the wrist view and let the fingers close across it. The estimated midpoint of that pair is (245, 90) pixels. Assuming z = 0.77 m, I tentatively estimate its world position near (0.245, -0.061) m, consistent with the earlier rear-axle calculation of (0.2465, -0.0582) m. I therefore currently identify this as the rear axle and would target approximately (0.247, -0.058) m. That position is closer to the basket rim: with the ordinary downward pose, both fingers would remain near y = -0.058 m, and with +45° yaw one finger would extend toward positive X and positive Y, even closer to the rim. Moving the car into the foreground first, perhaps toward y = -0.15 m, should give this grasp more clearance. For the drag, I will repeat the front-body approach but translate while staying low instead of lifting. The bumper briefly appeared caught between the fingertips in observation 618; translating toward the robot at that point might have dragged the car. I considered reopening at a pre-grasp height of z = 0.98 m, moving to the front-body pose at x = 0.267 m, y = -0.087 m, z = 0.93 m with the gripper downward, closing for three steps, and then dragging toward y = -0.20 m at z = 0.94 m for ten steps. I also considered splitting the approach into two three-step motions, followed by three steps of closure and the drag, roughly 20 steps overall. The current empty gripper is already at z = 0.998 m, so I can skip a separate pre-grasp move. My immediate action will reopen and descend toward (0.267, -0.087, 0.93) m with the downward orientation for six control steps while holding the left arm steady. The requested descent is 0.068 m, and I expect those six steps to reach approximately z = 0.93 m. This approach was previously clear of the basket, but I still need to check that it does not push the car into the rim. After inspecting, I plan to close for three steps and drag for ten steps toward y = -0.20 m, keeping x = 0.267 m and z = 0.94 m. That height is only 0.01 m above the grasp height, so I expect the car to remain on the table. If it slips out during the drag, I will inspect its new position before proceeding.

The green car’s front body is between the open right fingers, ready for the supported slide. I will close the right gripper for three control steps while holding both arms steady and keeping the left gripper open.

I will slowly drag the green car toward the foreground, targeting the right end effector at x = 0.267 m, y = -0.15 m, and z = 0.931 m without lifting. I will keep the gripper commanded closed and use the exact downward orientation for eight control steps. If the body grip holds and the car slides, it should move downward in the high-camera image. I estimate that eight steps may produce about 0.04 m of motion.

The right gripper’s opening command is now 0, and the green car moved only slightly in the high-camera view, from (435, 227) to (429, 225) pixels. It slipped immediately rather than being dragged significantly, though it rotated slightly. I could try pushing instead of pulling: place the closed gripper behind the rear bumper at z = 0.9 m and push forward, provided the small gap beside the red basket permits it. Another possibility is to push toward +X from the car’s left side, between the blue basket and the green car. That might move it along the front of the basket with enough clearance, but I still need a reliable grasp. I should try the visible rear tire pair, which I have not actually grasped yet, using an approach similar to the successful red-car grasp. A downward orientation with a small forward Y offset may keep the fingers off the rim without needing to drag the car first. The right end effector is currently at (0.267, -0.15, 0.931) m, closed and empty. The car appears near high-camera pixel (430, 226), with an estimated world center of (0.253, -0.076) m. I initially considered approaching the rear axle near (0.24, -0.06) m with the gripper open at z = 1.0 m, then inspecting the wrist view. At y = -0.06 m, however, both open fingers in the downward pose could be close to the red basket’s front wall, perhaps at y = -0.05 m. The earlier estimate for the gray rear axle was (0.2465, -0.0582) m. I will target the end effector at (0.246, -0.075, 1.0) m instead. This places its center approximately 0.017 m forward of the axle. With an estimated tire diameter of 0.04 m, the pads may still contact the front halves of the tires. If the rim is near y = -0.03 m, keeping the fingers at y = -0.075 m would leave about 0.045 m of clearance. A downward pose with 45° yaw would align more closely across the tire pair, but at a center Y coordinate of -0.075 m, the right finger could extend to y = -0.047 m and collide with the rim. The ordinary downward pose seems safer. Its closing direction is along world X, diagonal to the green car’s tire line, so it might contact one front tire and one rear tire diagonally rather than an exactly opposing pair. That could still be secure. I also considered pushing the car’s side to align its long axis with world Y before grasping. It already appears slightly rotated: its apparent long axis extends from about (421, 210) to (439, 237) pixels in the high-camera view, perhaps 30° from vertical rather than the earlier 45°. A world-X grasp across its width at that approximately 30° offset seems acceptable. I will reopen the right gripper and move to the rear-axle pre-grasp target of (0.246, -0.075, 1.0) m with the downward wxyz quaternion [0.5, -0.5, 0.5, 0.5] for six control steps, while holding the left arm steady. Then I will inspect the tire alignment and adjust X if necessary. If the rear tires appear near v = 200 pixels at pre-grasp height and near v = 300 pixels at the final approach, that should be suitable for contact.

The right arm has not reached its target after six control steps; its measured height is z = 0.965 m and its Y coordinate is -0.113 m. I will continue for six more steps toward the rear-axle pre-grasp target at [0.246, -0.075, 1.0] m. Only the green car’s front is visible in the wrist view, with its rear beyond the top edge. Moving back by +0.038 m along Y should bring the rear into the center of the view.

The entire green car is now visible in the right wrist view. Its rear spoiler appears near pixel (220, 50). The gray pieces near (250, 90) and (232, 140) might both be on the left side rather than forming a rear tire pair. I can distinguish a dark gray parallelogram near (290, 65) on the right side of the engine, a gray trapezoid near (250, 100) on the left side, and a gray quadrilateral near (235, 135) on the left or rear side. These might represent the front and rear tires on the left side, with a right-side tire occluded, but I am uncertain. I am trying to identify the model’s wheel geometry: the green sports car appears to have gray wheel hubs rendered as polygons at its four corners. With the rear spoiler at the upper left, the gray feature with a darker border near (232, 137) might be the rear left wheel, and the feature near (250, 89) might be the rear right wheel. However, those two points appear aligned vertically rather than across the car’s width, so I am not confident that they form a pair. I will use PIL to crop and enlarge the right wrist image, then view the detail to clarify which features are the wheels.

I’ll view the enlarged right-wrist crop to clarify which features on the green car are its wheels, so I can choose the tire contact points for the next grasp.

The gray shapes are engine vents or windows, rather than tires. The wheels are not visible from this top-down view; the black side pods cover them. I need to grasp the body lower down at the correct location to engage the hidden wheels. The rear spoiler is at the upper left and the front bumper at the lower right. The front axle is likely just behind the black front windshield, near the side pods and front fenders. My previous front-body grasp slipped, so a lower grasp across the rear tires near the spoiler and engine might work instead. I estimate the rear axle to be about 25% of the way along the car from the rear, between the spoiler and the engine’s rear window. In the crop, could the rear wheels be beside the gray engine vents near (250, 150) pixels? The rear quarter is wide around the engine. I tentatively place the rear axle center near original-image pixel (255, 100), perhaps crop pixel (315, 270), just behind the cabin. I targeted the rear axle at world coordinates (0.246, -0.075) m, where the end effector is now approximately positioned. The axle may appear near (260, 110) pixels, while the gripper’s horizontal image center is at 320 pixels. Do I need to shift right and up? I should estimate the axle positions from the car’s overall geometry. I estimate the rear spoiler endpoint at (210, 45) pixels and the front bumper at (370, 240) pixels, giving a length vector of (160, 195) pixels. Placing the rear axle about 25% along that vector gives (250, 94) pixels, and placing the front axle about 75% along it gives (330, 191) pixels. Where did my previous front-grasp target at world coordinates (0.267, -0.087) m fall in the image? At observation 612, the front windshield center was near (320, 260) pixels, the front bumper near (400, 360), and the rear was off to the left. I may have grasped near the front axle, but the fingers appeared to contact the front body near the hood, so I am not sure. In the current pre-grasp view, the front axle should be near (330, 190) pixels. That might map to world coordinates around (0.265, -0.067) m. If so, my previous target at (0.267, -0.087) m was 0.02 m too far forward and contacted the hood or bumper. I will use the wrist-camera calibration from observation 650 and an assumed axle height of z = 0.77 m to calculate world positions for the front axle at (330, 190) pixels and the rear axle at (250, 95) pixels.

The calculated rear- and front-axle X coordinates are approximately 0.224 m and 0.251 m, both left of my previous target at x = 0.267 m. In the high-camera view, the car center may be near x = 0.25 m and the rear spoiler near x = 0.22 m. The front axle is at image coordinates (330, 190) pixels, close to the gripper’s horizontal image center at 320 pixels. The current right end-effector position is (0.247, -0.081) m horizontally, already close to the revised front-axle target of (0.251, -0.089) m. My previous grasp at (0.267, -0.087) m was 0.016 m right of the axle, which I think caused the offset body contact and slipping. I will try a downward grasp at (0.251, -0.089) m and lower the end effector to z = 0.923 m. I estimate the open fingers at x = 0.291 m and x = 0.211 m, both at y = -0.089 m, with the right finger clear of the rim. This gives an estimated span of 0.08 m across the axle; the tire track is likely about 0.055 m and the open gap about 0.08 m, so the pads may contact the tires’ outer sides. I expect a centered tire grasp to produce an opening command around 0.36 rather than the previous 0.586, which I attribute to catching the wider front body off-center. I considered aligning at (0.251, -0.089, 1.0) m for four steps, then descending in two three-step actions before closing. Since the current height is already z = 0.995 m, I can skip that separate pre-grasp alignment and combine the small horizontal correction with a three-step descent. I also considered an initial height target of 0.93 m, but I will command (0.251, -0.089, 0.923) m with the downward wxyz quaternion [0.5, -0.5, 0.5, 0.5]. I expect three steps to bring the height to approximately 0.962 m while the horizontal alignment progresses. The right gripper will remain open, and I will hold the left arm steady.

I initially estimate the green car’s front axle near (360, 220) pixels in the wrist view, to the right of the gripper’s horizontal image center at u = 320 pixels. Perhaps the world X target should be 0.26 m rather than 0.251 m. Another possible axle location is (355, 235) pixels, giving a horizontal offset of +35 pixels. I first attributed this apparent rightward shift to moving the end effector left, but the measured motion does not support that: its X coordinate changed from 0.247 m to 0.249 m, actually +0.002 m. Its Y coordinate changed from -0.081 m to -0.084 m, a forward change of -0.003 m, and its Z coordinate decreased by 0.034 m. The changing perspective during descent may explain an apparent axle location near (365, 215) pixels instead. At the final end-effector height of z = 0.923 m, the axle should move downward in the image, perhaps with a similar horizontal coordinate. If the horizontal offset really is +40 pixels, I would consider increasing the end-effector X coordinate by about 0.01 m to 0.261 m, close to the earlier 0.267 m target. However, my identification of the axle pixels remains uncertain because the black wheels are covered. An angled, more horizontal camera view could reveal the side tires and help locate the axles in 3D, although I would still need to return to a top-down grasp. Another way to estimate the axle is from the car’s overall geometry. I estimate the front axle to be about 0.03 m behind the front bumper. I could locate the bumper and rear spoiler using projection with an assumed height of z = 0.77 m. In observation 650, I estimated the front bumper at (370, 240) pixels, possibly corresponding to world x = 0.274 m. An earlier calculation from observation 600 placed the bumper at approximately (0.295, -0.097) m horizontally, but the car may have moved since then. For the current observation 653, I initially place the front bumper near (383, 285) pixels, or the bottom of the nose near (385, 285) pixels. Looking at the bumper’s endpoints, I estimate them near (360, 292) and (430, 255) pixels, with a center near (395, 273) pixels. The rear spoiler center appears near (160, 35) pixels, giving a front-minus-rear image vector of (235, 238) pixels. Estimating the front axle at 70% of the way from the rear gives approximately (324, 202) pixels. That is close to the gripper’s horizontal center at u = 320 pixels, so the current alignment may be correct after all. I expect the axle to appear near (330, 300) pixels at the final approach, still approximately centered. The X target of 0.251 m may therefore be appropriate. I will continue the descent and inspect the gap during closure. If this grasp holds, it may resolve the pickup; if it slips, I can try the rear axle next. There are 447 control steps remaining. For now, I will continue for three steps toward an end-effector height of about 0.93 m, keeping the grippers open and the left arm steady.

At the right end-effector height of z = 0.929 m, I initially estimate the green car’s front axle near wrist-image pixel (360, 300), possibly close to the right finger. The front bumper appears near (415, 370) and the rear spoiler near (40, 80). Estimating the front axle at 75% of the way from the rear gives (320, 300), centered horizontally at x = 320 pixels, so the alignment looks good. The open fingers are at x = 125 and 515 pixels, near y = 260 pixels. The tire pair may be near (220, 240) on the left and (410, 180) on the right. Another estimate places the right tire near the black feature at (420, 200) and the left tire near the black feature at (210, 310), giving an average of (315, 255). That looks well centered between the pads. I will close the right gripper while holding both arm poses for three control steps. If the fingers contact the tires, I expect the reported opening command to be around 0.35.

The right gripper’s opening command is 0.497. The green car has rotated slightly, and the fingers appear at x = 180 and 455 pixels in the wrist view, contacting its front fenders. I will make a three-control-step test lift toward a right end-effector height of z = 0.98 m to check whether the grasp holds.

The green car has again slipped toward its front bumper, with the fingers near image coordinates (250, 260) and (380, 260) pixels and an opening command of 0.218. The hold is not secure. The tapered front body makes the fingers slide toward the nose; the rear body may offer broader, more vertical surfaces and better tire contact, so I will try the rear axle. The rear-axle estimate from observation 650 was (0.224, -0.0547) m horizontally, but the car has moved and rotated since then. It now appears near (435, 229) pixels in the high-camera view, with its rear spoiler near (150, 50) pixels in the wrist view. The right end effector is at (0.251, -0.089, 0.965) m, with the front bumper caught between the fingers. I tentatively estimate the rear axle’s current horizontal position at (0.228, -0.060) m. I could open and align above it at z = 1.0 m in the downward orientation. Rim clearance remains uncertain. At x = 0.228 m with the gripper downward, I estimate the open fingers at x = 0.188 m and 0.268 m, both near y = -0.06 m. Is the basket’s front-left region approximately x = 0.2–0.44 m and y = -0.02 m? What world Y coordinate corresponds to the front wall near high-camera image y = 209 pixels? I could project the wall-top point at (400, 198) pixels using an assumed z = 0.84 m; I tentatively estimate world x = 0.17 m, but have not determined its Y coordinate. In the current wrist view, the red wall is behind the spoiler, which appears almost under the rim. The rear axle is slightly forward of the spoiler, but a rim near y = -0.06 m could still obstruct the fingers. Could a -45° yaw or another orientation keep the fingers on the table side? The +45° yaw that aligns closure across the green car’s narrow axis puts the right finger toward the basket and would make clearance worse. The ordinary downward pose may fit if the axle is near y = -0.06 m and the front rim is near y = -0.02 m, leaving a 4 cm gap. I estimate the open fingers’ thickness along Y at about 0.02 m, so that may provide enough clearance. The earlier rear approach at y = -0.075 m never reached a descent, so its feasibility remains untested. I will reopen the right gripper and move to (0.225, -0.06, 1.0) m with the downward wxyz quaternion [0.5, -0.5, 0.5, 0.5], using six control steps. This should release the front bumper and raise and reposition the gripper over the rear region. I will then inspect its centering before descending.

The green car’s rear axle appears near wrist-image coordinates (330, 160) pixels, just ahead of the spoiler near (300, 130) pixels, while the front is near (390, 280) pixels. The gripper’s horizontal image center is at u = 320 pixels, so the alignment looks good. The red basket rim is near v = 120 pixels, just above the spoiler. The fingers are around image y = 260 pixels, with the fingertips near v = 255 pixels, and appear clear of the rim. During the final descent, I expect the rear axle to move toward v = 300 pixels, while the rim may remain near v = 120 pixels. The fingers’ rear geometry could still hit the rim, but in the downward orientation the open fingers lie along world X and their bodies project vertically. The right finger near (515, 260) pixels is away from the rim at v = 120 pixels. Do the fingers extend upward far enough to overlap it? Their visible tops and tips appear near v = 255 pixels, with the rest below, so I see no current overlap. As I descend, the rim may move upward out of view, which suggests the path will remain clear. The rear axle may be aligned with the current end-effector horizontal position of x = 0.228 m and y = -0.065 m. At the current pre-grasp height of z = 0.995 m, with an assumed object height of z = 0.77 m, would an axle aligned in X and Y project near v = 190 pixels? The earlier formula gave v = 176 pixels for an end-effector height of 1.0 m and object height of 0.77 m, so the observed v = 160 pixels is reasonably close. I will retain the current horizontal position and descend toward z = 0.923 m in two three-step increments, starting with three control steps.

The red basket rim occupies much of the wrist view at v = 160–215 pixels, obscuring the rear spoiler. The green car’s rear axle appears near (340, 220) pixels, just below the rim. The fingertips are at v = 255 pixels, so there is no apparent overlap with the rim. I am unsure how the rim’s projection will change as the camera descends. Could its vertical image coordinate increase as the lower end effector brings the camera closer to the rim at an estimated z = 0.84 m? It may instead move upward and out of view. In observation 584, the rim appeared only on the right side; with the current downward orientation, it spans the top of the view. Even without image overlap, the open finger bodies could physically contact the rim behind the car. I should proceed cautiously in one-to-three-step increments. I will continue toward a right end-effector height of z = 0.923 m for three control steps.

The right wrist view is now entirely blocked by the red basket wall, but the arm reached z = 0.925 m without pose deviation. Is the camera behind or inside the rim? The high-camera view shows the fingers near the green car, but I cannot see the object in the wrist view. I could use the head camera and the estimated geometry, or lift slightly to restore visibility. The open gripper is at the previously aligned rear-axle position. The rim may be between the camera and the car rather than obstructing the fingers. The lack of pose deviation suggests that the fingers have not collided with it. The camera looks toward −Y and downward from a position 0.051 m ahead of the end effector. With the end effector at y = −0.065 m, I estimate the camera at y = −0.014 m and z = 0.84 m. The red front rim is approximately at y = −0.014 m and z = 0.84 m, which would explain the occlusion. The fingers remain at y = −0.065 m, in front of the rim, so I believe they are clear. Based on the prior alignment, closing across the rear axle should work. I will hold both arm poses and close the right gripper for three control steps, then lift and inspect the grasp once it is back in view.

The right gripper’s opening command is 0.422, which is moderate. In the high-camera view, the green car has moved and rotated from diagonal to vertical, suggesting that the fingers engaged its rear body or tires and rotated it during closure. This looks promising, but the grasp still needs verification. I will make a three-control-step test lift toward a right end-effector height of z = 0.98 m; this should also bring the wrist camera clear of the basket rim.

The rear grasp appears secure: the green car’s rear bumper is between the fingers, possibly with contact on the rear side tires, and the reported opening command is 0.365. In the wrist view, the red rim is near v = 180 pixels and the car’s rear is near v = 250 pixels. The car appears to hang between the fingers, with its rear flush against the gripper, but I am not certain it is fully lifted. In the high-camera view, the car is near (433, 229) pixels and its front nose is near y = 248 pixels. After the end effector’s 0.037 m lift, the rear may be raised while the front still touches the table, leaving the car tilted. The opening command has settled from 0.422 after closure to 0.365, which suggests the grasp is likely holding. I will raise the right end effector and move it forward, along negative Y and away from the basket rim, to confirm full clearance. I will target [0.25, -0.10, 1.03] m with the gripper closed and the downward orientation, using six control steps. With the rear held, the nose may pivot downward, but I expect the car to lift clear.

The rear grasp appears secure: the reported opening command is stable at 0.356, and the car’s rear remains steady in the wrist view. In the high-camera view, its nose is near image y = 247 pixels, close to the table but apparently lifted. It may be hanging almost vertically, nose down, because I am holding the rear and its center of mass is farther forward. That orientation is acceptable for container placement, which has no orientation requirement. The right end effector is at (0.25, -0.1, 1.029) m. The rear is held near the fingertips, but the nose may extend about 0.25 m below the end effector. Is it lifted enough to clear the basket? At an end-effector height of approximately 1.03 m, I tentatively estimate the rear bumper at z = 0.87 m and the nose at z = 0.77 m, about 20 mm above the table. To clear the estimated red-basket rim at z = 0.84 m, I might need an end-effector height around 1.10 m, although reaching forward over the basket at that height could be difficult. I could tilt the gripper to level the car or point its nose upward. Alternatively, once the nose is above the basket interior, I could lower it in first and release so the rear follows. The important issue during transport is keeping the nose clear of the rim. If its current bottom is around z = 0.79 m, I estimate that raising the end effector by 0.06 m to about 1.09 m would provide clearance. One possible path is to raise near the current staging position of x = 0.25 m, y = -0.1 m, z = 1.03 m, then move to x = 0.35 m, y = 0 m, z = 1.06 m, lowering once the car is inside. Tilting backward could also raise the nose relative to the end effector, but the tire grasp is stable and that change may be unnecessary. The car’s attitude is still uncertain. When I grasped its rear at end-effector z = 0.925 m, I estimated the rear axle at z = 0.77 m and the nose on the table at z = 0.75 m. The lift to end-effector z = 1.029 m was +0.104 m. If the car remained horizontal, the rear axle would now be at z = 0.874 m and the nose at z = 0.854 m, enough to clear the rim. The wrist view shows only the rear, but that could be normal occlusion from a low rear viewing angle rather than evidence that the car hangs vertically. In one reading of the high-camera view, the rear is near (443, 206) pixels and the front near (450, 245), giving an apparent length of 39 pixels compared with an original length of 44 pixels. Another reading puts them at (442, 210) and (450, 247), giving 37 pixels compared with the original top-down length of approximately 45 pixels. Those differences are not large. At observation 680, the wrist view showed the rear and engine; at observation 686, it shows only the rear. The gripper remains downward, so did the viewing angle change, or did the car rotate into a vertical plane? It could be hanging rear up and front down, or merely tilted about 30° with the nose lower. I will raise toward z = 1.08 m for rim clearance rather than rely on the horizontal interpretation. I initially considered lowering inside with an end-effector pose at x = 0.36 m, y = 0 m, z = 1.03 m. The red car is already in the basket, perhaps toward the right or center, so I considered putting the green car on the left or allowing it to rest partly atop the red car while contained. However, I should avoid contact with the red car during lowering. The high-camera view places the red car near (432, 173) pixels, on the basket’s left side, leaving a possible green-car placement near (475, 180) pixels on the right. The basket center is approximately x = 0.32 m. Is the red car’s actual X coordinate about 0.26 m? Using another image estimate near (430, 175) pixels suggests approximately x = 0.24 m, y = 0.04 m. I therefore favor placing the green car on the right, near x = 0.38 m, y = 0.03 m. I also need to account for holding the green car at its rear axle. Its current rear-axle X coordinate may be about 0.25 m. Does its nose extend toward +X? In the high-camera view, the rear near (444, 210) pixels and nose near (450, 245) suggest only about 0.01 m of X difference, so its long axis is mostly along world Y. I briefly considered an end-effector placement at x = 0.38 m, y = -0.005 m. Is the car center forward of the rear axle along +Y? Looking again, the rear spoiler is higher in the image near y = 206 pixels and the front bumper lower near y = 245 pixels, toward the robot. That suggests the rear is toward +Y and the front toward -Y, with the center approximately 0.03 m in negative Y from the rear axle. To put the car center near y = 0.04 m, the rear-axle end-effector position might need y = 0.07 m. The estimated basket interior extends to y = 0.13 m. With a rear spoiler offset of +0.03 m, it could reach y = 0.10 m, while a nose offset of -0.09 m would put the nose near y = -0.02 m, approximately the front interior boundary. An end-effector Y coordinate of 0.06 m therefore seems suitable. For comparison, the red car’s front-axle grasp used end-effector y = 0.005 m, with its center offset +0.03 m to y = 0.035 m; the green rear-axle grasp requires a different offset. Would a forward pose at y = 0.06 m, z = 1.03 m, x = 0.38 m be reachable? It is near the right base’s approximate x = 0.3 m, but the forward reach remains uncertain; could the relevant distance be around 0.38 m? Lowering may help. I will first stage at (0.36, -0.04, 1.08) m, then consider a final pose at (0.38, 0.05, 1.02) m, moving +0.09 m in Y and lowering 0.06 m. At that final pose, the nose bottom might be around z = 0.84 m. If the car hangs with a vertical length of 0.12 m, a rear height around z = 0.86 m could put the nose at z = 0.75 m on the floor. If it remains horizontal, I estimate its bottom at z = 0.847 m with a drop of about 0.1 m. These are alternative estimates, not verified object heights. Placing at x = 0.38 m should also leave space around the red car. The estimated basket’s inner right boundary is x = 0.44 m, and the green car’s width is about 0.07 m, so x = 0.38 ± 0.035 m appears to fit. Estimating the red car at x = 0.27 ± 0.05 m gives approximately 0.11 m between their centers. For the immediate action, I will move the closed right gripper toward the staging pose (0.36, -0.04, 1.08) m while retaining its downward orientation. From the measured pose, the planned displacement is (+0.11, +0.06, +0.051) m, with an estimated distance of 0.135 m. Raising along this path should provide clearance as the car moves from in front of the basket toward its rim. I will use eight control steps and hold the open left arm steady.

The green car remains secure. In the high-camera view, its nose appears near image y = 220 pixels, and its rear may be near y = 170 pixels. It is above the red basket’s front-right edge. In the right wrist view, the red rim is at the top and the car’s rear is below it; this looks acceptable. I will continue toward the right-arm staging position [0.36, -0.04, 1.08] m for six control steps, then proceed to the final placement approach.

The direct placement target failed the local reach check, so I should use a closer, lower intermediate pose. I will target the right end effector at (0.345, 0.0, 1.04) m. Relative to its current measured pose, this is a change of (-0.009, +0.047, -0.033) m, with a distance of approximately 0.058 m. This nearer target will likely pass the precheck. Afterward, I plan to continue to y = 0.04 m and z = 1.0 m. I will use four control steps for the intermediate motion.

In the high-camera view, the green car appears near pixel (493, 185), over the red basket’s right interior or right wall. Its front may still be outside. The red rim fills the top of the wrist view, with the green car’s rear below it; is the car still outside the front wall? The right end effector is currently at (0.346, -0.01, 1.042) m. I want to continue forward while lowering it toward the final target of (0.34, 0.04, 1.0) m. I estimate the target distance at about 0.06 m, within the motion limit, and lowering Z should help reachability. For this action, I will try the smaller target of (0.34, 0.03, 1.0) m, moving forward by 0.04 m and down by 0.042 m, over four control steps.

The top of the green car’s body is visible in the wrist view, with the red car inside the basket to the left and the green car over the right interior. In the high-camera view, the green car is near pixel (491, 184) and appears fully inside the rim. The right wall is close, but the car appears contained. Before releasing, I need to assess its support. The right end-effector height is 1.001 m. I estimate the rear grasp point at about 0.84 m, the lower front nose at about 0.78 m, and the basket floor at 0.75 m, so the nose is likely resting on or near the floor. Release seems stable: I expect only a small drop, and resting on its side or at an angle is acceptable inside the basket. I will hold both arm poses and open the right gripper for four control steps, then inspect the result.

The green car has been released into the red basket, but only a small green portion is visible near pixel (488, 187) in the high-camera view. In the wrist view, the car spans approximately v = 200–480 pixels, with its front at the bottom near v = 480. Could the front extend over the front rim, or is the car lying flat on the floor? The red basket floor extends behind it, and the front wall may be near v = 420 pixels. I should withdraw the gripper and inspect the whole basket to verify containment. The high-camera view appears to show three watches in the white basket, two peppers in the blue basket, and both cars in the red basket, with the table clear. The sorting looks complete. I expect native_success to remain false until the required arm return is complete, but I must not report success until it is true. Both grippers are open and pointing downward. The left end effector is at [-0.2, -0.22, 1.04] m, and the right is at [0.34, 0.021, 1.001] m over the red basket. Before resetting, I need to move both arms into clear space away from the baskets and objects. I considered retracting the right arm directly to [0.3, -0.25, 1.04] m, but its planned displacement of [-0.04, -0.271, +0.039] m has an estimated distance of 0.276 m, exceeding the 0.25 m limit. Another option, [0.30, -0.22, 1.04] m, has a displacement of [-0.04, -0.241, +0.039] m and an estimated distance of 0.247 m. That is within the limit but close to it, and the precheck may be difficult. I will use the nearer intermediate target [0.32, -0.16, 1.05] m instead, with a displacement of [-0.02, -0.181, +0.049] m and an estimated distance of 0.188 m. The left arm may already be clear, but I will move it to [-0.3, -0.30, 1.02] m. Its planned displacement is [-0.1, -0.08, -0.02] m, with an estimated distance of 0.13 m. I will use 10 control steps for both arms, keep both grippers open, and retain the downward wxyz quaternion [0.5, -0.5, 0.5, 0.5]. The right withdrawal moves toward negative Y and upward, which appears to take its open fingers safely away from the green car. Afterward, I will check that the car remains inside the basket. Once both arms are clear and containment is verified, I plan to use robot_reset. The reset will handle returning toward the initial poses, including the left start position of approximately [-0.3, -0.352, 0.922] m. From the planned clearance poses, the left arm would be about 0.1 m from its start position, while the right at [0.32, -0.16, 1.05] m would be about 0.23 m from its start at [0.3, -0.352, 0.922] m. Both also need a substantial orientation change from downward fingers to the initial 90° Z orientation with horizontal fingers. I am considering 50 reset steps. Earlier rotations took about 30–40 steps, and reset uses direct joint interpolation, so the 50-step maximum may be enough. I will inspect afterward and call again if the episode remains active and the arms have not returned. There are 388 control steps remaining. Unless the green car falls out or the inspection reveals another placement problem, no further object manipulation should be needed. For now, I will retract both arms.

The right end effector reached y = -0.028 m from y = 0.021 m, a change of -0.049 m, despite a target of y = -0.16 m over 10 control steps. That is surprisingly slow, perhaps because the arm is near a singularity or reach limit. It is still over the basket. I am not yet certain that the green car is fully contained. In the wrist view, its front appears near v = 250 pixels, below the apparent red front wall near v = 215 pixels. More specifically, the front bumper appears at (394, 261) pixels and the wall’s lower edge near v = 217 pixels, with the table below. If the bumper is in front of the wall, the car could be balanced across the rim with its front outside. The high-camera view shows only the car’s rear near (489, 187) pixels, with the front hidden by the wall. The current right end-effector position is [0.334, -0.028, 1.027] m. From this wrist viewpoint, the red wall appears as a horizontal band spanning image y = 180–220 pixels, while the green car spans y = 40–260 pixels. Could perspective make the front bumper appear beyond the wall while it is still inside? If this is the front wall between the camera and basket interior, an object behind it should be occluded unless it is above the wall. Is the car above the wall or resting on it? I estimate the released car’s height at z ≈ 0.80 m and the rim at z ≈ 0.84 m. If the car is lying flat behind the wall, the wall should hide its lower part. Seeing the entire car, including its front below the wall, therefore makes me suspect it may be straddling the front rim. However, the high-camera view argues against that interpretation. If the front were outside, I would expect to see it on the table in front of the red basket, below image y = 212 pixels. After release, only a small green portion appears near (489, 187) pixels; there is no green car visible around (500, 230) pixels on the table. That suggests it is contained. Could the red band near wrist v = 220 pixels instead be the back wall? The camera looks downward toward -Y, and the front wall is closest to the robot at negative Y, so I would expect it lower in the image and the back wall higher. The band near v = 200 pixels may be the front rim, but that identification remains uncertain. The car’s front could also blend into the red wall in the high-camera view, where only a small green portion is visible near (488, 187) pixels. I should not reset while containment remains uncertain. Enlarged crops of the high-camera and right-wrist views could help, but first I will finish withdrawing the right arm so it no longer blocks the basket. The left arm is already clear and will hold its measured pose. I will keep both grippers open and use 12 control steps to continue toward the right target [0.32, -0.16, 1.05] m. Once the arm is farther away, I can inspect the fuller high-camera view and the new wrist view for support, settling, or any part of the car outside on the table before deciding to reset.

Only a tiny part of the green car is visible near pixel (474, 184) in the high-camera view of the red basket. Is it beneath the gripper? The right gripper still partly occludes the basket’s left edge, limiting the view of the car. The right wrist view now shows only the table, so the camera has moved forward and the object is behind it. I will crop and enlarge the high-camera view to inspect the basket more closely.

I’ll view the enlarged high-camera crop to check whether the green car is fully contained and supported in the red basket before returning the arms.

Only a tiny part of the green car is visible near the red basket’s front-right wall and beneath the gripper, but it appears to be inside, just behind the front wall. It may be lying on its side in the front-right corner with only its rear visible. I should retract the right gripper farther to get a clearer high-camera view before resetting. The right end effector is currently at [0.324, -0.126, 1.047] m and appears near pixel (500, 190) in the high-camera view, obscuring the green car. I will move it to [0.30, -0.28, 1.05] m. The planned displacement is [-0.024, -0.154, +0.003] m, with a distance of approximately 0.156 m. The left arm is already clear and will remain stationary. I will use 10 control steps for the withdrawal, which should clear the view of the basket contents.

In the high-camera view, the green car is visible near pixel (485, 184). Its green top and black stripe appear to lie near the red basket’s front-right corner, entirely behind the front wall. No objects remain on the table. I believe the required arm reset is the only remaining condition keeping native_success false. Both arms are in clear, open space: the left end effector is at [-0.293, -0.297, 1.021] m, and the right is at [0.307, -0.238, 1.05] m. Both grippers are open and point downward, at an estimated height of z ≈ 0.89 m, above the table with no nearby objects. The reset may swing the arms, but they now have clearance. I will call robot_reset with 50 control steps and inspect the resulting observation. This should satisfy the required arm-return condition.

The final observation reports native_success as true, so I can report the supplied successful outcome. The reset feedback also reports reached_home as false, and the final joints are not exactly at home, with an error of approximately 0.3065 rad. I should therefore describe the episode as ending successfully after the arm-return action rather than claim that the arms reached their exact home configurations. I considered whether to mention reached_home as false, but the supplied outcome is task success. I will briefly report that all seven objects were sorted: three watches in the left basket, two peppers in the middle basket, and two cars in the right basket. I will mention native_success as true after the arm-return action and take no further robot actions.
