I need to operate the robot to sort all wooden_toy objects into the left basket, watches into the middle basket, and cars into the right basket. There are 1100 control steps available. I should first read the relevant robot-manipulation skill and inspect the observation, camera calibration, and images to identify the objects and estimate their positions. My tentative reading of the head-camera view is that the wooden toys are two brown carved elephants at the left front and a small yellow bunny near the center-left. There may be a silver watch at x approximately -0.12 and another at x approximately +0.25. The cars appear to be green in the center and yellow on the right. I tentatively count seven objects: three wooden toys, two watches, and two cars. The watches appear near image coordinates (196, 243) and (408, 294); the green car appears near (357, 255), and the yellow car near (464, 284). I need to verify these classifications and understand the coordinate geometry before sorting. I’ll read the skill file and observation JSON and list the files.

My inverse projection formula appears to have a sign error: the positions calculated on a fixed z plane do not project back to the original image coordinates. I need to check the derivation for the head camera. The camera coordinates are camera_y = -0.866*y - 0.5*z + 0.29893 and camera_z = 0.5*y - 0.866*z + 1.33776. With b = (v - 240)/f = camera_y/camera_z, this gives b*(0.5*y - 0.866*z + 1.33776) = -0.866*y - 0.5*z + 0.29893. Rearranging carefully, (0.5*b + 0.866)*y = -b*(-0.866*z + 1.33776) - 0.5*z + 0.29893 = b*(0.866*z - 1.33776) - 0.5*z + 0.29893. I used the opposite signs in the previous inverse formula. I should fix it.

The triangulated object heights of z = 0.82–0.86 m suggest that the table may be at z = 0.8 m, with object tops around z = 0.85 m. My earlier table estimate of z = 0.75 m was too low. The initial end-effector height of 0.9215 m would put it about 0.12 m above the table. The basket rims may be around z = 0.93 m. The proposed correspondence for the first elephant’s top, at head-camera pixel (136, 229) and left-wrist pixel (194, 315), triangulated poorly: z was approximately 0.887 m, with an error of 0.024 m. That suggests I matched different points. Pairing head-camera pixel (136, 229) with left-wrist pixel (190, 380) instead yielded z = 0.822 m and an error of 0.0004 m. However, is that wrist point actually the top? It may be the side of the saddle, so I still need to check whether it matches the point selected in the head view. Perhaps the initial images were rendered at different sizes, although their recorded dimensions all match at 640 × 480 pixels. I should inspect the head and wrist views with coordinate grids to identify exact matching points. I’ll prepare crops with grid lines every 40 pixels, enlarge them by a factor of two, save them, and then inspect them with the image viewer.

The triangulation results vary with the chosen image points, so the cross-view correspondences are still uncertain. I’ll inspect the enlarged head-camera image with its coordinate grid to locate object features more precisely for matching with the wrist views.

The grid labels show the original pixel coordinates even though the image has been doubled in size. I can now estimate the head-camera object positions more accurately: the first elephant’s center is perhaps at (139, 239), the second elephant at (198, 293), the bunny at (238, 232), the first watch at (196, 243), the green car at (356, 255), the yellow car at (462, 283), and the second watch at (408, 294). I’ll inspect the left-wrist view next.

Only one elephant is visible in the left-wrist view, centered around pixel (195, 375). Which elephant in the head view does it correspond to? It might be the second elephant, but triangulating that correspondence gave a large error of about 0.13 m. Could this be a calibration issue? I also considered whether the object at head-camera pixel (139, 239) might be another wooden toy, perhaps a hedgehog or a seated carved elephant, or whether the two views showed the same object twice. However, the head view shows two distinct objects at (139, 239) and (198, 293). The second elephant at (198, 293) is closer to the camera, toward negative Y, and has a less negative X coordinate. Perhaps it is behind or to the right of the wrist camera’s field of view. With the wrist camera’s approximately 78° optical field of view, an object this close could fall outside the bottom or right of the image. I therefore think the visible wrist elephant is the farther, first elephant; some point correspondences for that elephant triangulated reasonably. The second elephant appears to be too close and below the initial wrist view. Matching the first elephant’s body center at head-camera pixel (139, 239) with wrist pixel (195, 375) gave an approximate world position of x = -0.38 m, y = -0.03 m, z = 0.84 m, with an error of 0.015 m. This could be a point on the body’s surface. Could the table actually be at z = 0.75 m? The elephant’s foot is near wrist image y = 460 and its base near head image y = 256. Pairing head pixel (143, 255) with wrist pixel (150, 460) might give z around 0.79 m. I’ll calculate more identifiable feature correspondences to check. The first elephant’s saddle top may be at head pixel (137, 225) and wrist pixel (200, 311), though the matching points might instead be (139, 225) and (190, 310), which could still give a substantial triangulation error. For the highest rear point of the saddle, I’ll try head pixel (139, 225), with its horizontal coordinate roughly in the 136–146 region, and wrist pixel (193, 310), where the top of the rug begins around (192, 310). Is the elephant facing left in the head view? Its saddle appears above a trunk extending down the left side. In the wrist view, the head is around (150, 380) and the trunk reaches (150, 455); in the head view, the head is around (130, 247) and the trunk reaches (130, 256). The trunk tip at head pixel (132, 256) might correspond to wrist pixel (145, 458). That should provide an accurate correspondence to test. I’ll calculate these points.

The table now appears to be around z = 0.75–0.76 m, with object tops around z = 0.85 m, so my earlier table estimate of 0.75 m is plausible. The first elephant’s base at head-camera pixel (139, 255) may correspond to world x = -0.438 m and y approximately -0.001 m, though I am uncertain about that estimate. I’ll inverse-project the head-camera points at z = 0.75 m. Where exactly is the top center of the large elephant? For a grasp, I need to position link6 so the fingertips reach the object. With local +X pointing downward, the fingertip position is the link6 position plus 0.1576 m times (0, 0, -1), so link6 z should equal the desired finger-contact z plus 0.1576 m. If the table is at z = 0.75 m and the object is 0.1 m tall, a grasp contact around z = 0.80 m would require link6 z around 0.958 m. The initial link6 height of 0.9215 m would be too low if I rotated downward at the same position, putting the tips around z = 0.764 m. I should raise to z = 1.05 m for the approach. The initial end-effector orientation is horizontal, with the fingers around z = 0.92 m and object tops around z = 0.85 m. I should move above the object at z = 1.05 m, then descend to z = 0.96 m or 0.94 m. Could the basket rim be around z = 0.90 m? If the table is at z = 0.75 m, perhaps the basket is 0.12 m tall. In the head view, the basket front is around pixel y = 210 and the back top around y = 140. In the left-wrist view, the front bottom is around y = 310, possibly at table height, and the rim around y = 230. What height does triangulating the front-bottom center at head pixel (192, 210) and wrist pixel (350, 310) give? I’ll calculate basket correspondences to establish the table and basket positions. For the back-rim center, I could use head pixel (192, 140) and wrist pixel (320, 158), though the wrist x coordinate is uncertain. The white basket’s center is around head x = 192 and wrist x = 350 because of the different camera viewpoints. I’ll also test the front-bottom center at head pixel (190, 210) and wrist pixel (350, 309), and the front top rim at head pixel (190, 192) and wrist pixel (350, 230). The front bottom may be at z = 0.75 m; I’ll check with triangulation.

Some triangulation errors are around 0.03 m, perhaps because I chose mismatched points, but why does the basket’s front bottom come out at z ≈ 0.87 m? If the table is at z = 0.75 m, I would expect the front bottom to be at 0.75 m rather than 0.87 m. Perhaps the basket bottom rests at z = 0.75 m while the visible front-bottom feature is at z = 0.78 m. The pairing of head-camera pixel (192, 210) with left-wrist pixel (350, 309) has an error of about 0.012 m, which is not especially large, yet its calculated height of z = 0.872 m seems improbable under that table estimate. Could the table instead be at z = 0.85 m? The elephant’s trunk tip triangulated to z = 0.759 m, however, and if it touches the table, that supports a table height near 0.75 m. A basket front bottom at z = 0.87 m would then appear to float about 0.12 m above it. This inconsistency could indicate that the camera calibrations do not align, or that I badly mismatched the points’ horizontal positions. The white basket appears centered at x = 350 pixels in the left-wrist view and x = 192 pixels in the head view, which seems plausible. Its front bottom is around head-image y = 210 and wrist-image y = 310. The rays should intersect if these are the same point; the error is about 0.012 m. Perhaps the head-image feature at y = 210 is actually on the closer face at z = 0.80 m, while the wrist-image feature at y = 310 is at table contact, with different horizontal positions. I could check against assumed physical dimensions: perhaps the table is at z = 0.75 m and the basket is 0.13 m tall. Inverse-projecting the front-bottom head-camera point at z = 0.75 m might give x ≈ -0.293 m and y ≈ 0.173 m, but I need to calculate that. What wrist-image vertical coordinate would it predict? I’ll use the inverse-projection and projection utilities to map candidate head-camera pixel (192, 210), fixed at z = 0.75 m, into the wrist view.

Projecting the basket’s head-camera pixel (192, 210) at z = 0.85 m gives left-wrist pixel (345, 177), whereas I identified the front bottom at left-wrist pixel (350, 309). That is a large vertical mismatch. Could I have misread the calibration, used the extrinsics incorrectly, or encountered an image-calibration issue? The front bottom appears around y = 310 pixels in the left-wrist image. At z = 0.75 m, the projected head-camera point gives left-wrist y = 226 pixels. To reach y = 309 pixels, it seems I would need a lower z or a closer y position. The triangulation yielded z ≈ 0.872 m. Could the proximity of the rays explain this? With a separation error of about 0.012 m, I would expect the triangulated point to project close to both selected pixels, but perhaps that error produces a large image displacement. I should verify the reprojection directly. For the reported point P = (-0.2719, 0.0342, 0.8724) m, should the head-camera projection be (192, 210)? The earlier inverse calculation at z = 0.85 m gave x = -0.279 m and y = 0.051 m, close to (-0.272, 0.034) m; at z = 0.872 m, it would give approximately x = -0.265 m and y = 0.025 m. Yet the left-wrist projection at z = 0.85 m gives y = 177 pixels rather than 309, and at z = 0.872 m with world y = 0.034 m, it might give image y around 150 pixels rather than 309. Is there an error in the triangulation function? The ray construction seems correct: the environment-to-optical transform is p_camera = R p_environment + t. A pixel defines the camera ray [a, b, 1], whose world direction is R.T @ ray, with camera center C = -R.T @ t. A point on that ray should reproject to the selected pixel because K(RP + t) = K(s ray). If the two ray points P and Q are close, their projections should also be close to the selected wrist pixel. The projection expression is q = K @ (T @ np.r_[p, 1])[:3]. Python’s operator precedence appears to make this the intended multiplication of K by the first three components of the transformed point. Could overwriting t with a scalar in the triangulation function be a problem? In the ray function, t is the translation vector; in the triangulation function, s and t are the least-squares ray parameters, used in P = C + s*d and Q = E + t*e. Those uses seem valid. The inverse calculation or projection function may still be wrong. I’ll test triangulation and reprojection together, inspecting the ray centers, directions, parameters, points, and direct wrist-camera transforms.

The head-camera projection of P gives v = 161 pixels rather than 210 pixels, even though P = C + s*d should lie on the ray for the original pixel. The rotation check gave T[:3, :3] @ d = [-0.444, 0.265, 1.0017], rather than the ray I expected, [-0.444, 0.636, 1]. Is d incorrectly normalized, or is there a problem with the ray function’s array construction or intrinsic-matrix values? If d = R.T @ ray, then R @ d should recover the ray when R is orthonormal. Could the calibration matrix fail to be a rotation? The head-camera matrix [[1, 0, 0], [0, -0.866, -0.5], [0, 0.5, -0.866]] is orthonormal, and the left-wrist matrix is approximately orthonormal. However, I just realized that the printed rotation check applied the left-wrist rotation to the head-camera world ray. Since those are different cameras, that comparison with the original head-camera ray is irrelevant. The head-camera reprojection of P is still inconsistent. The operator precedence in the ray function’s return expression appears correct, and I have not overwritten d. I’ll check the head-camera calculation directly by comparing R @ P + t with s*ray and printing the ray, camera transform, and intermediate values.

Multiplying K by the camera-space point gives [115.6, 97.48, 0.602]. Dividing by the third component gives pixel coordinates approximately [192, 161.86], rather than the expected vertical coordinate of 210. With camera-space y = -0.1633, the focal-length term is -78.13, and adding 240 gives 161.87. The normalized vertical ray coordinate should have been (210 - 240)/288 = -0.1041667, but the printed ray is [-0.44424, -0.27116875, 1]. Looking at the command, I found the error: I used (v - K[1,1])/K[1,1], subtracting the focal length of approximately 288 pixels instead of the vertical principal point, cy = 240 pixels. The subtraction should use K[1,2]. This mistake appears throughout the ray and generic inverse-projection functions. My first manual inverse formula used v - 240 correctly but had the wrong sign for y; the subsequent generic formula used the wrong cy. I’ll change the vertical normalization to (v - K[1,2])/K[1,1] and rerun the triangulation and inverse-projection calculations. That should make the triangulation consistent.

The corrected camera calculations are consistent with a table height around z = 0.75–0.76 m and basket rims around z = 0.84 m. The white basket’s front bottom might be at z = 0.75 m, although triangulating head pixel (192, 210) with wrist pixel (350, 309) gave z = 0.787 m with an error around 0.010 m. This may still be a correspondence issue: I see the front bottom around wrist y = 310 and head y = 210. The rim estimate of 0.84 m seems more reliable. The left basket’s interior center may be near x = -0.28 m and y = 0.06 m. Its left and right rim corners have x values around -0.404 m and -0.142 m, suggesting a center at -0.273 m. The head-camera rim center at u = 192 gives an x estimate that depends on the assumed z = 0.84 m and y around 0.04 m. The triangulated front rim at head pixel (192, 192) is approximately (-0.275, -0.013, 0.830) m, and the back rim at (192, 141) is approximately (-0.299, 0.127, 0.841) m. These suggest a center around (-0.287, 0.057, 0.84) m. I estimate an internal width around 0.22 m and depth around 0.20 m. For placement, I can use approximate horizontal centers of (-0.28, 0.06) m for the left basket, (0, 0.06) m for the middle basket, and (0.28, 0.06) m for the right basket. For the first elephant, triangulation gives a point around (-0.37, -0.114, 0.798) m. Is that its top or another surface point? Its body centroid may be around (-0.38, -0.10, 0.785) m. A grasp near the back saddle could be around (-0.37, -0.09, 0.82) m, with the fingers contacting the body’s sides around z = 0.79 m. Its width may be 0.07 m and its length 0.10 m. I do not know the maximum gripper opening; perhaps it is 0.08 m. If the body is about 0.07 m wide, the left arm may be able to grasp across it along world X. The small bunny’s center may be around (-0.18, -0.09, 0.78) m. The flat left watch is around (-0.263, -0.11, 0.77) m. The second elephant’s estimated base is (-0.25, -0.207, 0.75) m, with a top around z = 0.81 m and horizontal center near x = -0.25 m, y = -0.20 m. It appears too close to be visible in the initial wrist view. The right watch’s estimated base has horizontal coordinates (0.1776, -0.2137) m; the yellow car is near (0.2965, -0.1901) m and the green car near (0.0803, -0.1254) m. These head-image points may lie on body tops around z = 0.78 m, so their horizontal estimates could shift slightly. I should use the actual top-height estimates. For the green car’s center pixel at y = 255, inverse projection at z = 0.78 m might give x around 0.0756 m and y around -0.14 m, though that y estimate is uncertain. I can approach approximately and refine from a downward-looking wrist view. For the first motion, I’ll orient both grippers downward and move above the nearest targets: the second elephant near (-0.25, -0.20) m for the left arm and the yellow car near (0.30, -0.19) m for the right arm. They are close to their respective arms and separated. A downward orientation with local Y along world X closes the fingers along world X. The second elephant appears diagonal or vertical in the head image, with body width around 0.06 m along world X and length around 0.08 m along world Y, so closing along X seems suitable. The yellow car is diagonal, with its image long axis running from about (450, 296) to (474, 267), a vector of (24, -29) pixels. Its world direction is uncertain; perhaps its yaw is -45°. Since the car is flat, I could inverse-project those points at table z = 0.77 m to estimate its direction. The bottom-left to top-right image direction suggests positive world X and positive world Y, perhaps a long-axis direction around (1, 1.5). A perpendicular closing direction could be (-1.5, 1), or approximately local Y = (-0.7, 0.7, 0), while local X points downward. I can construct the orientation from these columns and their cross product. Alternatively, the simpler downward quaternion [0.5, 0.5, 0.5, -0.5] in wxyz order puts local Y along world X. That may still grasp the car diagonally at its roughly 0.04 m-wide roof if centered. I should refine the alignment from the wrist view. The wrist camera moves with link6, so after rotating downward I can use its pixels and an estimated surface height to refine the target by inverse projection. I plan to approach above the objects at link6 z = 1.05 m. The proposed left move from (-0.3, -0.352, 0.922) m to (-0.25, -0.20, 1.05) m is about 0.225 m, within the 0.25 m target-distance bound. The rotation requires an intermediate orientation, however. I initially wondered whether the change from the initial 90° Z rotation to the downward quaternion was 1.57 rad or perhaps 2.094 rad, both above the 1.0 rad limit. For q0 = [0.707, 0, 0, 0.707] and q1 = [0.5, 0.5, 0.5, -0.5], the dot product is 0.3535 - 0.3535 = 0, giving an angle of π. This downward orientation is therefore 180° from the initial orientation. Could an alternative downward orientation with local Y along world -X be closer? I considered quaternion [0.5, -0.5, -0.5, -0.5], with a tentative dot-product calculation of 0.3535 + 0.3535 = 0.707 and angle 1.571 rad, still above the limit. I should determine the nearest downward orientation rather than rely on that tentative quaternion. Initially, local X points along world +Y. Starting with Rz(90°), a +90° world-X rotation would send +Y to +Z, which is upward. I need a -90° world-X rotation instead, giving Rx(-90°) Rz(90°). This sends local X downward to (0, 0, -1), leaves local Y at (-1, 0, 0), and sends local Z to (0, 1, 0). The resulting matrix is [[0, -1, 0], [0, 0, 1], [-1, 0, 0]]. Its quaternion may have a dot product around 0.707 with the initial quaternion, corresponding to about 1.57 rad. I should split that change through a 45° intermediate orientation using spherical interpolation, so each rotation is about 0.785 rad, below the 1.0 rad bound. A direct downward target could be rejected by the orientation-distance check. I’ll use SciPy to calculate the downward quaternion and its halfway orientation, checking the candidate with closing along world -X.

The downward quaternion [0.5, -0.5, 0.5, 0.5] in wxyz order puts local Y along world -X, so the fingers close along world X; the sign does not matter for this closing direction. I’ll first use the halfway quaternion [0.65328148, -0.27059805, 0.27059805, 0.65328148]. One possible intermediate position is (-0.25, -0.22, 1.03) m for the left arm and (0.30, -0.21, 1.03) m for the right. My left-distance estimate is sqrt(0.05² + 0.132² + 0.108²) = 0.178 m, below the 0.25 m limit. The right distance may be about 0.142 m. The orientation change is about 0.785 rad, below the 1.0 rad limit. I considered five control steps, but with increments limited to 0.02 m and 0.1 rad per step, I estimate six steps for translation and eight for rotation. I’ll use eight steps for this approach and orientation change. The fingers need clearance while rotating downward. At the halfway orientation, local X points approximately along (0, 0.707, -0.707), so the 0.157 m finger extent points partly along +Y and partly along -Z. With link6 raised to z = 1.03 m, the tips would be around z = 0.919 m, above the estimated object height of 0.82 m and basket rims at 0.84 m. I judge this approach safe. The horizontal positions are near the objects, and the right gripper should be approximately above the car. I’ll target (-0.25, -0.20, 1.03) m above the second elephant with the left arm and (0.30, -0.19, 1.03) m above the yellow car with the right arm, keeping both grippers open and using the halfway orientation. I’ll call robot_act with obs_000000.

The measured motion is much smaller than requested. After eight steps, the left link6 position is (-0.294, -0.332, 0.94) m. My initial rough estimates were only 0.022 m of translation and a rotation change of 0.02; I also initially estimated the quaternion change at 0.1 rad. Looking more closely, the left position changes are approximately +0.0055 m in X, +0.020 m in Y, and +0.0185 m in Z, while the orientation change from the initial pose is about 0.198 rad, or about 0.025 rad per step. Perhaps the small motion comes from the local IK's joint-increment limits and coordinated scaling. A distant target might require around 50 steps. I should judge progress from the measured poses rather than assume the target has been reached. The current left quaternion is [0.704, -0.07, 0.071, 0.703] in wxyz order, compared with the intermediate target of approximately [0.653, -0.271, 0.271, 0.653]. The initial-to-intermediate rotation is 0.785 rad, so the observed 0.198 rad is about 25% of that change. At this rate, reaching the intermediate orientation might take another 24 steps, followed by 40 more to point fully downward, for approximately 64 additional orientation steps. I also estimate about 50 steps for a 1.57 rad rotation. Translation may proceed at roughly 0.003 m per step because of joint scaling; the observed Y motion gives 0.020/8 = 0.0025 m per step. A target translation of 0.178 m might take around 60 steps. I could continue toward the target in calls of up to 15 steps: four calls are one possibility, while five calls would allow about 75 steps for the approach. Perhaps motion will become faster as the joints move away from the initial configuration, where all joints were zero and the damped IK might be affected by a singularity. I should inspect the next 15 steps before drawing conclusions. The 1100-step budget could be tight for seven objects if each move takes around 100 steps; the overall work might require 700 or more steps. There are now 1092 steps remaining, so I need to average fewer than 156 steps per object, including the reset. A pickup and transport might take around 100 steps, which still seems workable. The downward orientation with local Y along world -X will rotate the wrist view by 180° relative to the prior view. I could consider another grasp orientation: the alternative with local Y along world X was π rad from the initial orientation and could eventually be reached by a different path. For now, the current path toward the chosen downward orientation seems fine. The intermediate target is 0.785 rad from the initial orientation, and the arm has progressed about 0.2 rad along that change. I’ll request 15 steps toward the same intermediate positions and orientation, keeping both grippers open and continuing along the same clear approach paths.

The left-wrist view now shows both elephants: the first at the top left and the second near the bottom center. The right-wrist view shows the yellow car near the bottom center and a watch at the left edge. I should finish orienting the grippers and align the grasp points. The current left link6 position is (-0.254, -0.209, 1.037) m, with quaternion [0.602, -0.37, 0.371, 0.602] in wxyz order. The orientation is still partial—perhaps around 45°, or a pitch of about -56°? I may need another eight control steps to reach the downward orientation. The end effector’s horizontal position is almost above the second elephant’s estimated position of (-0.25, -0.207) m, yet that elephant appears near wrist pixel (400, 440). This may reflect the camera’s mounting offset. How will the wrist camera sit relative to the end effector once it points fully downward? The image center may not coincide with the finger contact point. I can use the calibration and current pose to refine object positions by triangulating matching points in the head and wrist views. In obs_000035, the partly downward-facing wrist cameras show the second elephant’s body and the yellow car. The objects appear unchanged in the head view. For the second elephant, a tentative saddle-center correspondence is head pixel (198, 292) and left-wrist pixel (400, 430), although I estimate the wrist saddle center closer to (395, 433). For the first elephant, head pixel (139, 239) may correspond to left-wrist pixel (70, 190), or perhaps the saddle is around (70, 180); I could use that later. For the yellow car, I can try head pixel (463, 284) and right-wrist pixel (285, 390), though the roof center may be closer to (285, 382). The right watch at head pixel (408, 294) may correspond to right-wrist pixel (75, 410), partly hidden behind a finger. I could inspect the saved obs_000035 images with a grid if needed. For now, I’ll calculate triangulations using manually estimated correspondences.

The triangulation for the second elephant suggests x ≈ -0.22 m, compared with the earlier head-camera plane estimate of -0.25 m. Its surface center may be around (-0.23, -0.21, 0.81) m. What X coordinate would inverse-projecting the head-camera saddle center at pixel (198, 292), with z = 0.81 m, give? Perhaps about -0.228 m. I’ll use an approximate horizontal center of (-0.23, -0.21) m. The current left-arm X coordinate is -0.254 m, so it needs about +0.024 m in X; its Y coordinate of -0.209 m is already suitable. Would closing along world X grasp across the elephant’s body? In the lower part of the wrist image, the elephant’s length and the saddle’s long axis appear roughly vertical. With the camera pointing downward, image vertical may correspond to world Y. The body is about 90 pixels wide in the wrist view. The chosen downward orientation puts local Y along world -X, and image horizontal may correspond to world -X or +X. Closing horizontally therefore seems appropriate for grasping across the body width. A possible grasp target is x = -0.23 m, y = -0.205 m. I want finger contact around z = 0.79–0.80 m. With the object top around z = 0.82 m and the table around z = 0.75 m, I could grasp its sides at z = 0.785 m, using link6 z = 0.9476 m. I’ll approach at z = 1.05 m first; one possible pose for finishing the orientation is (-0.23, -0.205, 1.04) m. The yellow car’s estimated center is (0.281, -0.20, 0.779) m. I should align the closing direction across its width. The chosen downward quaternion puts local Y along world -X. In the right-wrist view, the car’s long axis looks roughly vertical with a slight diagonal, perhaps from bottom left to top right. Its top is around pixel (310, 320) and its bottom around (240, 450), giving a long-axis image vector of (-70, +130) pixels, pointing down and left. That may correspond roughly to world Y. Horizontal closure across its width seems suitable enough, so I’ll retain the downward quaternion. A possible approach target is (0.281, -0.20, 1.03) m before descending. I’ll finish pointing both grippers downward with their horizontal positions aligned, using eight to ten steps. I initially considered left link6 z = 1.04 m and right z = 1.03 m. With the car around z = 0.79 m, a link6 height of 1.04 m would put the fingertips around z = 0.88 m, clear of it. The elephant’s top is around z = 0.82 m, leaving only about 0.06 m below fingertips at z = 0.88 m. That seems adequate, but could the fingers sweep into it while finishing the rotation? I considered finishing at z = 1.06 m for added clearance before descending. The current fingers are not fully downward, and their lowest extent may be around z = 0.95 m; I have observed no collision. I’ll now target left link6 z = 1.05 m and right z = 1.04 m, keeping both grippers open, and request ten steps.

Both grippers are now nearly pointing downward. I estimate the elephant’s center in the left-wrist image at pixel (350, 235) and the car’s center in the right-wrist image at (320, 180). The black fingers appear along the lower left and right edges, but where exactly are their tips? The finger pads appear to occupy x = 0–120 pixels on the left and x = 520–640 pixels on the right, with tips near y = 260 pixels. The closing line may be around y = 270 pixels. At the correct relative pose, the object should appear between the fingers, but I need to determine the intended contact pixel from the calibration and finger geometry. I can use the current link6 pose and camera extrinsics to project the fingertip center into the wrist image. Its world position is the end-effector position plus R × [0.1576, 0, 0] m, where R is the current link6 rotation. The actual contact might instead be around local x = 0.13 m. For obs_000045, I’ll calculate the projected fingertip and possible grasp-contact locations. The object should align with the contact point’s pixel at its surface height; perspective changes while link6 remains above it. I could calculate a target end-effector position from a triangulated object position and the desired contact offset. Triangulation using obs_000045 should be more accurate. Alternatively, I can directly inverse-project a wrist pixel onto an estimated object-surface height. Since the wrist cameras are nearly vertical, this should give accurate horizontal coordinates. For the calculation, I’ll use the elephant’s body center at pixel (350, 230) with surface z = 0.80 m, and the car’s center at (320, 175) with surface z = 0.775 m. I’ll use the current camera calibration to estimate their world X and Y coordinates, then align the end-effector contact locations with them. I’ll also compute the fingertip projections.

The left-wrist inverse projection places the elephant’s grasp center at approximately (-0.2167, -0.2274) m in world X and Y, rather than the expected (-0.23, -0.21) m, where the left end effector currently is. Points along the finger axis project at image x = 320 pixels, while the elephant’s center is at x = 350 pixels, indicating an offset. With local X pointing exactly along world -Z, the gripper axis would be vertical, so the end effector’s horizontal coordinates should match the grasp center. The current orientation still has a slight Y component of about 0.008. I’ll target left X = -0.217 m and Y = -0.227 m, a correction of approximately (+0.013, -0.017) m. The right-wrist inverse projection gives the car’s horizontal center as approximately (0.2813, -0.1994) m, essentially aligned with the current right end effector. Its center is at image x = 320 pixels. The car’s image y = 175 pixels corresponds to the assumed surface height of z = 0.775 m, whereas the current fingertip is at approximately world z = 0.881 m and Y = -0.19 m, projecting near image y = 275 pixels. Could the vertical image difference come from the lower object height and camera perspective? Yes, the camera offset can change image Y for points with the same world X and Y at different heights. I should align using the calculated world coordinates; the right arm is already approximately correct. The selected elephant pixel (350, 230) may still be imperfect as a grasp center. Its saddle spans roughly image y = 150–310 pixels, with the head near y = 300 pixels and the tail near y = 150 pixels, so (350, 230) seems appropriate for the body center. The car pixel (320, 175) may represent its roof or center. For descent, link6 z should equal the desired contact height plus the contact’s local X offset. Perhaps contact should be near local x = 0.13 m. The farthest finger extent is 0.1576 m, and I estimate that the pads extend from local x = 0.07 m to 0.157 m. Contact at an object-side height of z = 0.78 m with local x = 0.13 m would put link6 at z = 0.91 m. Earlier I considered z = 0.95 m using the fingertip, but I need the fingers to reach the object’s sides without bottoming out on the table. If the fingertips reached the table at z = 0.75 m, link6 would be at z = 0.9076 m using the 0.1576 m extent. A link6 height of z = 0.92 m would instead put the tips at z = 0.7624 m, about 12 mm above the table, with the pads extending upward from approximately z = 0.762 m to perhaps 0.90 m. That seems suitable for an object about 0.07 m tall, with a grasp center around z = 0.78–0.80 m. I’ll use z = 0.92 m as the intended grasp height for both objects. The descent from z = 1.05 m to 0.92 m is approximately 0.13 m. I considered doing it in 15 steps, or using five steps near contact, but the grasp instructions call for only one to three steps per action throughout approach, alignment, closure, and test lift. I’ll use three-step actions. The remaining orientation error is only about 0.08 rad, so I can finish the orientation while correcting the horizontal alignment and beginning the descent, although three steps may not fully reach the target. Subsequent three-step actions might descend about 0.015 m each. The immediate targets will be left (-0.217, -0.227, 1.02) m and right (0.281, -0.199, 1.01) m, with the exact downward quaternion and both grippers open. The actual descent may be only about 0.01 m. I can then continue gradually toward z = 0.93 m, perhaps over roughly eight calls; there is enough control budget. I also considered rotating the car gripper for more precise alignment. The car’s image long axis runs approximately from (335, 105) to (290, 250) pixels, tilted about -15° from vertical. A perpendicular closing direction would be tilted about 15° from horizontal. However, horizontal fingers still seem suitable across its narrow, flat roof. The elephant’s long axis appears vertical, making horizontal closure appropriate. I’ll retain the orientation and execute three steps of alignment and open-finger descent.

The elephant’s body is centered near wrist-image pixel (310, 220), and the car near (320, 190). Is the black inner edge of an open finger close to the object? In the right-wrist view, the left finger appears black with a small yellow patch at its tip. Could it already be contacting the car? The left finger occupies roughly image x = 0–120 pixels, and I interpret the yellow patch at (90, 290) as a reflection rather than part of the car. The car spans roughly image x = 200–430 pixels, and the open gap appears sufficient, perhaps about 0.08 m. I should descend toward link6 z = 0.95 m, then 0.925 m. For this three-step action, a target of z = 0.962 m might result in an actual height around 0.964 m. I’ll target left link6 z = 0.962 m and right link6 z = 0.952 m; the car may be shorter, allowing the right gripper to descend farther.

At the left link6 height of 0.964 m, the fingertip is at z = 0.8064 m, compared with the elephant’s estimated top at z = 0.82 m. The right fingertip is at z = 0.7964 m, compared with the car’s roof at z = 0.78 m. The fingertips are therefore around the objects’ upper sides. In the images, the elephant’s body is approximately 180 pixels wide, while the fingers’ inner edges are at x = 125 and x = 515 pixels, leaving a gap of 390 pixels. The elephant appears much narrower than the gap, so the fingers will need to close substantially. The car is approximately 230 pixels wide within a 390-pixel gap, which also looks sufficient. I’ll descend toward left link6 z = 0.935 m, putting its tips around z = 0.777 m, and right link6 z = 0.925 m, putting its tips around z = 0.767 m. With the table estimated at z = 0.75 m, the right tips would have 0.017 m of clearance. A three-step action might move about 0.029 m. For the immediate action, I’ll use left z = 0.936 m and right z = 0.928 m.

The objects now appear very large because the wrist cameras are close, and the elephant’s body extends beyond the bottom of the image. Is the gripper at the correct Y position? The elephant’s center may now be near image y = 400 pixels; perhaps the axis projection changes with height. I should not use the image center to realign now, since the current world X and Y positions are fixed. The fingers are visible around image x = 0–125 pixels and y = 260–400 pixels on the left, with the right finger around x = 520 pixels. The elephant’s body edges appear near x = 160 and x = 460 pixels, so it seems to fit within the gap. The car’s edges appear near x = 140–520 pixels. Its right finger may be touching it, though the grippers are still open. The left finger-pad tips are at z = 0.7794 m, close to the elephant’s side at about z = 0.78 m. The right tips are at z = 0.7714 m, within the car’s estimated side heights of z = 0.76–0.79 m. These heights seem suitable for closure. I’ll close both grippers for three steps, holding position and orientation steady, then inspect the next observation.

After three control steps, the opening commands are 0.354 for the left gripper and 0.558 for the right, so closure is still interpolating. Perhaps three more steps will bring the pads into full contact. The black fingers appear to be against both sides of the elephant’s body, and the car’s fingers likely contact its sides near the wheels, though these contacts are not certain. I considered combining continued closure with a lift, but I should let the grip stabilize first. I’ll command another three steps of closure with both poses fixed, then make a three-step test lift. There is enough control budget for this sequence.

The opening commands have plateaued at 0.316 on the left and 0.559 on the right, which I take to indicate gripping contact. I’ll make a small vertical test lift of +0.03 m over three control steps, targeting left link6 z = 0.967 m and right link6 z = 0.959 m while holding orientation and grip steady. I’ll then check the wrist and head views to see whether both objects move with the grippers.

At first glance, both objects seem to have lifted, but I am not confident yet. The elephant’s body may be near head-image y = 300 pixels, and the car appears near y = 285 rather than its previous y = 284. The car’s orientation in the wrist view has changed dramatically: its long axis is now vertical and centered. The right opening command has decreased to 0.405. Could the car have slipped or rotated? It appears held between the fingers at its middle sides after the approximately 0.03 m lift, but its head-image position near (470, 285) could still indicate that it is on the table. The yellow car was originally near head pixel (464, 284), then near (467, 284) after grasping and (472, 286) after lifting. It has not visibly moved upward in the image. I expected y around 270 pixels after a +0.03 m lift, so its apparent position near y = 285 makes me question whether it lifted. In obs_000057, it extended beyond the bottom of the wrist image; in obs_000066, it is fully visible from approximately y = 100 to 410 pixels and appears smaller. That could mean the camera lifted away from a car still on the table. Its changed orientation could also mean the fingers rotated it during closure or lifting. I should verify with another lift to link6 z = 1.02 m and inspect the head view before transporting it. The elephant remains large in the left-wrist view. In the head view, it appears near (193, 294), compared with its original position near (197, 292), so it has moved little. Could it still be on the table and slipping? I need to compare its apparent world position with the end effector rather than assume it is held. The left link6 is now at z = 0.965 m. If the elephant is held with a local-X offset around 0.13 m, and its top was at z = 0.82 m when link6 was at z = 0.937 m, the top’s vertical offset would be -0.117 m. Its new top would then be at z = 0.848 m. For an elephant center at world coordinates (-0.218, -0.226, 0.848) m, what would the head-image coordinates be? I estimate image v around 249 rather than the old 291 pixels, an upward change of 42 pixels. Yet the elephant still appears near y = 294, suggesting it may not have lifted. Using another estimate, the original object was near head pixel (197, 291) at z = 0.81 m. If held, it might now be at (-0.218, -0.226, 0.838) m and project near (198, 265). Its visible body center instead seems near (194, 293), again nearly unchanged. Perhaps the fingers are not actually holding it, and the wrist view only changes because the camera lifts above a stationary object. The elephant extends beyond the bottom of both obs_000057 and obs_000066, though it may have shrunk slightly. My tentative head-image estimates for the elephant are (194, 291) in obs_000057, perhaps (196, 298) in obs_000060, (197, 298) in obs_000063, and (194, 295) in obs_000066. These indicate small movement rather than the expected upward movement from a 0.03 m lift. Could the fingers be contacting too high and pushing it along the table instead of lifting? The left opening command plateaued around 0.316, but perhaps that could represent an empty, mechanically limited closure rather than a grasp. Normally I would expect a closed command to approach 0 unless blocked. The right command changed from 0.559 to 0.405 after lifting; perhaps closure was still progressing rather than indicating stable contact. These values are interpolated opening commands, not measured finger gaps. Might they continue toward 0 at roughly 0.22 per step? From the initial command of 1.0 in obs_000057, three steps produced 0.354 on the left and 0.558 on the right in obs_000060. After another three steps, the values were 0.316 and 0.559, which could suggest contact constraints. After the lift, they were 0.317 and 0.405. Perhaps the right closure progressed only once the arm moved. I need another test lift rather than relying on these commands alone. I can compare the expected projections for a stationary object and a held object, starting with the estimated elephant top center at (-0.22, -0.215, 0.81) m. With link6 at (-0.218, -0.226, 0.965) m, a stationary elephant would remain unchanged in the head view. The wrist camera’s +0.028 m movement would increase its distance from the object and make the object smaller. The elephant’s tail top appears near wrist y = 120 in obs_000057 and y = 110 in obs_000066. At image y = 400, its body may have spanned x = 170–470, about 300 pixels, in obs_000057; in obs_000066, its edges may be around x = 210–500, which is similar. A firmly held object with no rotation should remain at the same relative position in the wrist image because the camera orientation is unchanged. The images are not identical: the car changes from diagonal and large to vertical and smaller. It could have rotated within the grip, or it could still be on the table while the camera moves. The elephant’s tail appears near (380, 130) in obs_000057 and (380, 110) in obs_000066, with similar but shifted body edges. It could be held with minor slip, but that is still uncertain. Before deciding, I’ll enlarge the head-camera regions around the objects to look for a gap beneath them. I’ll use PIL to prepare crops for comparison from obs_000057 and obs_000066, including obs_000063, and may also inspect the wrist views.

The test lift has not clearly confirmed that the elephant and yellow car are held. I’ll inspect the enlarged head-camera crop from the latest observation for evidence that they are clear of the table.

The car’s long axis now appears vertical in the head image, although the car still seems to be lying flat. Is it held? The bottom of its wheels may be at image y = 296 pixels, compared with 303 pixels originally. The small vertical change might partly reflect its rotation from a diagonal alignment. The black fingers appear near the top of the car; perhaps they are holding its roof, with the car now around world z = 0.8 m rather than its original 0.78 m. That would be a lift of about 0.02 m, so the expected image change would be small. The elephant’s bottom appears at image y = 307 pixels rather than its original 313 pixels, an upward shift of 6 pixels after the measured 0.028 m lift. Is that plausible given the vertical projection scale? At object height z = 0.8 m, I tentatively estimate the derivative of image v with respect to world z at about -500 pixels/m, so a 0.028 m lift would produce about 14 pixels of upward motion. The observed 6 pixels could indicate only a partial lift. I should make a larger test lift to confirm both grasps. I considered targeting link6 z = 1.035 m for both arms, increases of 0.07 m on the left and 0.078 m on the right, over five steps. However, a test lift should use only one to three steps. I’ll instead request a +0.06 m lift for each arm over three steps; the actual motion may be around 0.05 m. I judge a fall from this 0.06 m test lift safe if a grasp fails. The targets will be left link6 z = 1.025 m and right link6 z = 1.017 m, with both grips and orientations held steady.

The head view now shows the objects lifted: the elephant’s bottom may be at image y = 302 pixels, and the car is at y = 290 pixels, higher than before. The car remains in the same relative position in the wrist view as in obs_000066, with its top near y = 90 pixels and bottom near y = 405 pixels, despite the camera lifting. The elephant also stays in the same relative position in its wrist view. I therefore consider both grasps confirmed. The measured link6 height increased by only 0.032 m during the three-step lift. I should now transport them to the baskets. The estimated horizontal basket centers are (-0.28, 0.06) m on the left and (0.28, 0.06) m on the right. The current link6 positions are (-0.218, -0.227, 0.997) m on the left and (0.281, -0.20, 0.989) m on the right. Before moving horizontally, I need enough height to clear the estimated rim at z = 0.84 m, accounting for how far the objects hang below link6. I initially considered an object-bottom offset of about -0.157 m or -0.17 m. For the elephant, however, link6 was at z = 0.937 m when its bottom was on the table at z = 0.75 m, giving an offset of -0.187 m. The fingertips were at z = 0.779 m, with the object bottom 0.029 m below them because I grasped its upper sides. If that offset stays fixed, link6 at z = 1.03 m would put the elephant’s bottom at z = 0.843 m, only just above the rim. I should use a transport height of 1.08 m or 1.10 m for clearance. For the car, the grasp height of 0.929 m and table height of 0.75 m suggest a bottom offset of -0.179 m; at link6 z = 1.03 m, its bottom would be at z = 0.851 m. I’ll lift both to z = 1.08 m before horizontal transport. A simultaneous five-step lift might produce about 0.08 m of actual motion, and both targets are within the 0.25 m distance limit. At a transport height of 1.08 m, the object bottoms would be around z = 0.89 m, above the 0.84 m rims. The left path from (-0.218, -0.227) m to (-0.28, 0.06) m passes near the bunny at approximately (-0.18, -0.07) m and the watch at (-0.27, -0.095) m. An object bottom at 0.89 m would clear their estimated tops at 0.82 m by 0.07 m. The right path to (0.28, 0.06) m may pass above the watch near (0.17, -0.22) m, but it should be clear of the table objects. Over the basket centers, the downward grippers at link6 z = 1.08 m would have fingertips around z = 0.922 m and object bottoms around 0.89 m, so I judge the rims clear. For placement, I need to lower each object inside its basket without letting the fingers strike the rim. A possible link6 height is 0.96 m, putting an object bottom around 0.77 m above the basket floor at 0.75 m. The fingertips would be around z = 0.802 m, below the rim but inside the basket. Precise centering matters so the fingers fit within the estimated 0.22 m internal width. I briefly considered the space needed with an open gripper; while holding, the object width is about 0.05 m and the outer finger span may be about 0.10 m, which should fit. Another placement option is to lower to link6 z = 0.97 m and release, allowing about a 0.02 m drop to the floor. For the wooden elephant, whose height is about 0.07 m and whose bottom offset is -0.187 m, link6 at 0.97 m would put its bottom at 0.783 m, about 3 cm above the floor. I expect that release to be stable. For the car, a possible bottom offset of -0.17 m would put its bottom at 0.78 m with link6 at 0.95 m; I could use 0.965 m instead. The head-view basket centers appear near pixel (192, 175) for the white basket and (448, 175) for the red basket. Earlier triangulation placed the left rim around x = -0.28 m and the right perhaps around +0.28 m, so I’ll retain basket-center targets at x = ±0.28 m and y = 0.06 m. I considered first lifting both arms to z = 1.09 m for five or six steps, since the vertical paths appear unobstructed, followed by about ten transport steps. However, the basket targets cannot be reached in one bounded command. The left horizontal displacement is (-0.062, +0.287, 0) m, with length 0.293 m, exceeding the 0.25 m limit. From a lifted pose of (-0.218, -0.227, 1.09) m to (-0.28, 0.06, 1.08) m, the distance would be 0.294 m. I need an intermediate Y position, such as -0.02 m, before proceeding to 0.06 m. An intermediate left pose of (-0.25, -0.03, 1.08) m would be about 0.199 m away, followed by a final move of about 0.09 m. On the right, the Y displacement is 0.26 m; combined with a roughly 0.09 m lift from the current height of 0.989 m to 1.08 m, the distance would be sqrt(0.26² + 0.09²) = 0.275 m, also above the limit. Even after lifting, the 0.26 m horizontal move needs an intermediate pose near y = -0.02 m. I could combine lifting with motion to those intermediate poses. From the current left pose to (-0.25, -0.03, 1.08) m, the distance would be sqrt(0.032² + 0.197² + 0.083²) = 0.216 m. From the current right pose to (0.281, -0.02, 1.08) m, it would be 0.201 m. Both are within the bound, but this would move the held objects forward while their bottoms start near z = 0.81 m, before clearing the 0.84 m rim height. The elephant’s initial bottom estimate is 0.997 - 0.187 = 0.81 m, above the watch’s estimated height of 0.78 m at y = -0.095 m. It could pass near the bunny, whose top is around 0.82 m at x = -0.18 m and y = -0.07 m, since the held elephant is near x = -0.22 m and about 0.06 m wide. By that part of the path, though, link6 might reach z = 1.06 m and the elephant’s bottom 0.87 m, providing clearance. The right car’s bottom also starts near 0.81 m; its path near x = 0.28 m should avoid the green car, and the watch is farther left near x = 0.17 m. I judge the combined paths potentially safe. I considered a twelve-step move toward the intermediate pose at y = -0.03 m and z = 1.08 m, then inspecting. Actual vertical and horizontal speeds might be about 0.02 m per step, so twelve steps could cover roughly 0.20 m. Although I expect clearance once lifted, a separate vertical lift first is safer near the other objects. I also considered four steps for that lift followed by twelve horizontal steps. There are 1031 control steps remaining, which is enough. I’ll now raise both link6 targets vertically to z = 1.08 m over five steps, keeping their horizontal positions, downward orientations, and closed grips unchanged.

After five steps, the link6 height is about 1.05 m rather than the target of 1.08 m. Perhaps another two steps would reach 1.08 m. Alternatively, I can continue lifting while moving toward an intermediate pose at z = 1.08 m and y = -0.03 m; the distance from the current pose is about 0.20 m. Using the estimated object-bottom offset, 1.05 - 0.187 = 0.863 m, which is already above the estimated rim height of 0.84 m. I therefore judge horizontal transport safe. I’ll target the intermediate positions (-0.26, -0.03, 1.08) m for the left arm and (0.281, -0.02, 1.08) m for the right arm. I’ll use 12 control steps because I have high confidence that the paths are clear.

The head view now confirms that the second elephant has been removed from the table, while the first elephant remains at image pixel (139, 241). The held elephant is at pixel (164, 199), and the car is at pixel (476, 209), both in the air. I should continue toward the basket centers. The measured left link6 position is (-0.246, -0.106, 1.063) m, and its target is (-0.28, 0.06, 1.08) m. The distance is approximately 0.17 m, below the 0.25 m limit. The measured right link6 position is (0.281, -0.097, 1.058) m, and its target is (0.28, 0.06, 1.08) m, approximately 0.158 m away. Twelve control steps may be suitable; I’ll use 12.

The precheck failed for both basket-center targets with the downward orientation, reporting position errors of about 65 mm. Could the targets at y = +0.06 m and z = 1.08 m be near a reach or joint limit? The arms started around y = -0.20 m and are now around y = -0.10 m; the target is only about 0.16 m farther forward, so I would expect it to be reachable. However, the downward orientation at x = ±0.28 m may constrain the wrist configuration. The identical failures on both sides suggest the targets might be about 0.065 m beyond the available workspace in this configuration, though that remains a hypothesis. Perhaps the maximum reach at z = 1.08 m is around y = -0.02 m, or the arms are fully extended at that height. The 65 mm residual suggests they might reach y = -0.005 m rather than +0.06 m. Would lowering to z = 0.98 m or tilting the fingers forward improve reach? If the bases are around y = -0.40 m, the horizontal reach might be about 0.50 m and the basket distance about 0.45 m, which seems feasible. The initial link6 pose at y = -0.352 m and z = 0.922 m had horizontal fingers; pointing downward may introduce a reach limit. I should inspect the robot’s morphology. The bases may be around x = ±0.30 m, y = -0.50 m, z = 0.95 m, with the table extending from y = -0.30 m to +0.30 m. A pitched-finger approach might reach the baskets more readily. I could try the same orientation at y = 0.04 m and z = 1.00 m or 0.98 m. Since the failed precheck executed no controls, I can change the target using the current observation. Another option is an intermediate pose at y = -0.01 m and z = 1.04 m, with estimated Y and Z change magnitudes of about 0.095 m and 0.023 m. That is within the command bound and seems likely to be reachable; moving there may also improve the subsequent basket-center precheck. I’ll target left link6 at (-0.28, -0.005, 1.04) m and right link6 at (0.28, -0.005, 1.04) m for eight steps, keeping the downward orientations and closed grips. These poses are nearer and slightly lower, with the held objects’ bottoms estimated around z = 0.85 m, still just above the rims. There could be front-rim contact if y = -0.005 m already puts the objects inside, but I judge the estimated clearance sufficient. After this intermediate move, I may try y = 0.06 m at z = 1.00 m.

The right gripper’s opening command is now 0.0, and the yellow car appears to hang below it near the red basket’s front edge rather than remain between the pads. In the right-wrist view, the car is around pixel (320, 230), apparently above the jaw tips and contact region; the black and red fingers extend from the bottom toward the image center. Could the car be lying on the table beyond the gripper? I take the fully closed command as confirmation that the gripper is empty, although I still need to inspect where the car ended up. It may have slipped during transport and landed on the table or basket edge. The left opening command is 0.314, and the elephant still appears held steadily over the white basket. I should place it first and keep the right arm stationary until I assess the car. The car’s location remains uncertain. In the head view, it appears near pixel (458, 214), below the red basket’s front. Another estimate puts it at (457, 213), with its bottom at image y = 228 pixels. Its original image y was about 284 pixels, so the new position could indicate greater height, possibly inside the basket, or a position farther along world Y. Assuming it lies on the table at z = 0.75 m, pixel (458, 214) would suggest approximately x = 0.29 m and y = 0.13 m, perhaps inside the red basket. I also estimate that inverse-projecting its base at z = 0.75 m would give y = 0.14 m and x = 0.29 m. Is that actually behind the basket center at y = 0.06 m? The red basket’s front bottom is near head-image y = 210 pixels. Earlier triangulation placed a front-face point around z = 0.78 m and y = -0.038 m, whereas interpreting image y = 210 pixels at table height z = 0.75 m gives world y around 0.14 m. The basket occupies roughly world y = -0.04 to 0.13 m, so a car at y = 0.14 m and z = 0.75 m might be near its back interior. Yet visually it seems to hang vertically against the outside front face, perhaps around y = -0.06 m and z = 0.79 m. I should triangulate matching head- and right-wrist points to determine its position. Perhaps I inadvertently placed it into the red basket; native_success is still false because other objects remain. If the car is contained, I can leave it. Otherwise, I will need to regrasp it. The right-wrist view seems to favor an outside placement: the basket bottom occupies image y = 0–180 pixels, there may be visible tabletop between the basket and car at y = 180–195 pixels, and the car’s top near y = 190 pixels may touch the rim. These interpretations are still tentative. Why did the right opening command change from 0.309 to 0 during eight steps? The car may have slipped, allowing the gripper to close completely. I should check rather than transport it farther. I considered opening the right gripper if it is empty, but opening might contact the car beneath it, so I will keep it closed at its current pose. The left link6 is currently at (-0.272, -0.035, 1.041) m. I estimate the elephant’s bottom at z = 0.854 m, above the white basket rim at z = 0.84 m, and it appears over the front-left interior. I’ll move toward a lower central placement pose at (-0.28, 0.04, 1.0) m, retaining the downward orientation and closed grip. I estimate the target distance at 0.083 m, and the precheck may pass now that the arm is closer. I’ll use six control steps for the left arm while holding the right at its measured position and wxyz quaternion [0.501, -0.499, 0.5, 0.5]. If the left precheck fails, I may try tilting its orientation forward. For now, I’ll approach the elephant’s placement pose without further right-arm transport.

The left-arm precheck was close, with a position error of about 8.8 mm. A slightly nearer target at y = 0.032 m and z = 1.0 m might pass. Another option is to tilt the fingers forward so local X points along (0, 0.2, -0.98), extending them toward world +Y. Would rotating the downward orientation about local Y achieve that? I could keep link6 at y = -0.02 m while tilting the finger axis toward +Y to move the held object’s center farther into the basket. I also need to understand the elephant’s offset from link6. It is held below link6, but could there be a slight additional offset? In the head view, its center appears near image x = 165 pixels, compared with the white basket’s center at x = 192 pixels. That might put the elephant at world x around -0.32 m rather than -0.28 m. I estimate its head-image position at (166, 180), toward the basket’s left side. With link6 at world x = -0.272 m, perhaps the object is instead around x = -0.30 m. Could it be offset within the grasp? I should use the wrist view to assess the held object’s relative position for placement. The elephant occupies the center of that view, but its body could still be offset: the gripper axis is at image x = 320 pixels, while the body center may be around x = 350 pixels. In the head view, an object center at x = 164 pixels versus the basket center at x = 192 pixels suggests it is roughly 0.06 m too far left. My tentative projection estimate puts link6 at head-image u = 194 pixels for world x = -0.272 m and z around 1.04 m. Using its measured y = -0.035 m and z = 1.041 m, I estimate u around 195 pixels, yet the visible finger center seems nearer x = 167 pixels, or perhaps 160 pixels. Am I comparing the fingers with the link6 projection? I’ll use the calibration from obs_000094 to project the measured end-effector poses into the head view and check the correspondence.

The held elephant appears at head-camera pixel (165, 180), near the predicted object-center horizontal coordinate of 178 pixels. The basket center is at 192 pixels, giving an offset of about 14 pixels, or approximately 0.035 m. I initially considered shifting right by +0.03 m and targeting x = -0.25 m instead of -0.28 m. Earlier triangulation placed the basket center at x = -0.28 m, though, and its head-image center at 192 pixels corresponds to that X coordinate at rim height z = 0.84 m. Could the elephant currently be at x ≈ -0.31 m? The predicted fingertip horizontal coordinate is 179 pixels, only 13 pixels from the basket center. Link6 is at x = -0.272 m, and the finger axis has the same world X coordinate. I now think the apparent horizontal offset comes from perspective at different Y and Z positions. The basket center at x = -0.28 m, y = 0.06 m, z = 0.84 m projects to u = 192 pixels, while the current finger-axis point at x = -0.272 m, y = -0.035 m, z = 0.883 m projects to u = 179 pixels. The current Y position is too near, rather than the X position being offset. Moving to y = +0.06 m should center the projection while retaining x = -0.28 m. The left target at y = 0.04 m and z = 1.0 m nearly passed the precheck. I could reduce Y to 0.03 m or lower Z to 0.99 m. Lowering might improve reach, although the error could involve an orientation singularity. A target at y = 0.03 m and z = 1.0 m should allow release near the basket’s front-center: the estimated basket extent is y = -0.04 to 0.13 m, so y = 0.03 m is sufficiently inside. At link6 z = 1.0 m, I estimate the elephant’s bottom at z = 0.813 m, about 0.06 m above the floor at z = 0.75 m and below the rim at z = 0.84 m. Releasing at y = 0.03 m should let it fall inside, so reaching exactly y = 0.06 m is unnecessary. I’ll try the left target (-0.28, 0.03, 1.0) m for five steps while holding the right arm steady.

The yellow car is now on the table near the front of the red basket, at head-camera pixel (462, 241), compared with (458, 214) previously. Did it move while the right arm was held stationary? It must have fallen between obs_000094 and obs_000099 as the physics settled. I’ll recover it. The left elephant appears at head-camera pixel (177, 172), still near the front of the white basket but inside it. After five steps, the measured left link6 Y position is 0.006 m rather than the target of 0.03 m, and its Z position is 1.008 m. The elephant’s bottom may be around z = 0.82 m, below the rim, within the basket’s front portion at y = 0.006 m. With the white basket’s estimated front edge at y = -0.04 m and back edge at y = 0.13 m, this position seems suitable for release. I’ll open the left gripper for three steps while holding both arms at their current poses and keeping the right gripper closed. Then I’ll inspect whether the elephant stays in the basket before withdrawing upward.

The released elephant appears nose-down or standing near the front of the white basket, around head-camera pixel (192, 171). Has it settled stably? The wrist view suggests it rotated during release and may be resting on its trunk or head. The task has no orientation requirement for container placement, so containment and stability are what matter. I consider it inside the white basket. The yellow car now appears flipped onto its side or roof at head-camera pixel (465, 252), and the right gripper is empty. I’ll recover it with the right arm and retract the left arm toward the next wooden object, perhaps the bunny or first elephant, followed by the left watch. The right arm can handle the car recovery, then the green car and right watch. There are 998 control steps remaining after 102 used, leaving roughly 140 per object. The car may have slipped because the roof grasp was not secure. The right opening command changed from 0.559 to 0.405 to 0.309 and then 0 during transport, suggesting gradual slipping followed by a fall. A lower grasp across the body, with the fingers near wheel height, might be stronger. Could aligning along its length help prevent rotation? The car began diagonal with the gripper closing horizontally across its body, then rotated until its long axis appeared vertical. It seemed stable initially, but perhaps the contact was only on the roof. I considered lowering link6 to z = 0.90 m instead of the previous 0.929 m, but that would put the fingertips at z = 0.742 m, below the estimated table height of 0.75 m, risking collision. I’ll instead aim for link6 z = 0.915 m, with the tips at z = 0.757 m, just above the table and low enough to contact the body. The previous grasp at 0.929 m put the tips at 0.771 m, contacting only the top 20 mm of a car estimated to be 0.04 m tall. That could work but may allow slipping. I should finish closure before lifting, perhaps in two stages. Now that the car is on its side, its height may be around 0.06 m, possibly making a grasp across its width easier. I need to inspect the right-wrist view once positioned above it. For the left arm, I considered retracting to z = 1.08 m and moving toward the bunny. At its current link6 position of (-0.278, 0.006, 1.008) m, however, the open fingertips are around z = 0.85 m, only just above the estimated rim at 0.84 m. A horizontal move could clip the rim, so I’ll first lift vertically to z = 1.09 m, allowing five steps. The right arm can open and move above the fallen car. Its head-camera center is approximately (465, 252), and its top on its side may be at z = 0.78 m. Inverse projection at that height might give x = 0.30 m, but I need to calculate it using candidate heights around 0.76–0.80 m. The current right link6 position is (0.281, -0.033, 1.041) m. Moving toward the car at an estimated y = -0.14 m might be about 0.18 m, within the 0.25 m command limit. Its closed fingertips are currently around z = 0.883 m, above the 0.84 m rim, so moving forward toward y = -0.15 m at that height seems clear. A provisional right approach target is (0.30, -0.15, 1.03) m with the gripper open and the orientation exactly downward. I estimate that target distance at 0.119 m. I could combine this with the left vertical retraction in a ten-step action; the left arm would hold its target after reaching it. After retracting, the left arm could approach the bunny near (-0.18, -0.08) m. The car may still be settling, since its position changed after it fell. Should I wait? The environment is probably stable now, so I can prepare above it and inspect before descending. First, I’ll calculate the head-camera inverse projections to refine the object coordinates.

The yellow car’s current horizontal position is approximately x = 0.305 m, y = -0.13 m. I’ll target the right link6 at (0.305, -0.13, 1.04) m above it and lift the left link6 vertically to z = 1.09 m. I’ll request 10 control steps.

The straight upward left-arm target at y = 0.006 m failed, which I attribute to a joint limit at this reach. Perhaps retracting toward negative Y while lifting will help. The right target may be feasible, but neither arm moved because the left precheck failed. I considered moving the left arm toward the front at y = -0.04 m while lifting to z = 1.08 m. The fingers are open and the elephant is inside the basket. Moving toward negative Y could risk contact with the front rim, although the fingertips are around z = 0.85 m, just above the rim. Is an open left finger already outside the basket, or do the fingers straddle the front rim in the head view? I also considered a slight 0.02 m lift while retracting toward y = -0.02 m. I’ll use a left link6 target of (-0.278, -0.04, 1.07) m, approximately 0.08 m away, which will likely pass the precheck. I’ll keep the same right target above the car at (0.305, -0.13, 1.04) m and request eight control steps.

The released elephant appears to be standing upright near the front-right of the basket, which seems acceptable. The yellow car may have moved again: I estimated its head-camera position at (465, 252) pixels in obs_000102, and it now appears near (483, 263) pixels in obs_000110. Did the right gripper collide with or push it while moving? It may instead have rolled after the fall without direct contact. The right gripper moved from above the basket to y = -0.084 m while opening, so a slight push is possible. In the right-wrist view, the car is visible near (390, 300) pixels and now appears upright on its wheels rather than flipped. Its estimated world position is around x = 0.34 m, y = -0.15 m. I should recompute the car’s position using the current right-wrist calibration and the exactly downward gripper orientation. I’ll inverse-project its estimated center at pixel (390, 295), assuming a roof height of about z = 0.78 m. For the left arm’s next object, I could choose the bunny, visible near left-wrist pixel (530, 230), the first elephant near (170, 280), or the watch near the center. The small bunny may be easier to pick. I can align the left arm above the bunny while aligning the right arm above the car. The left link6 is currently at (-0.278, -0.04, 1.07) m near the basket front, and I estimate the bunny’s horizontal position at (-0.18, -0.085) m. The move is about 0.11 m, within the command limit. I plan to move the open, downward-facing left gripper to (-0.18, -0.085, 1.04) m. This path may pass above the watch near (-0.265, -0.105) m as X changes from -0.278 to -0.18 m and Y from -0.04 to -0.085 m. With the fingers around z = 0.88 m and the watch around z = 0.79 m, I judge the path safe. I’ll determine the right-arm target from the inverse projection and calculate the car’s position first.

The car’s roof may be at z = 0.79 m: I estimate the table height at 0.75 m and the car height at 0.04 m. Inverse-projecting its center at right-wrist pixel (390, 295) onto z = 0.79 m gives horizontal coordinates approximately (0.332, -0.165) m. The right link6 is currently at horizontal coordinates (0.295, -0.084) m. A target of (0.332, -0.165, 1.03) m is about 0.094 m away, which seems suitable. I should align the gripper with the car’s long axis. My feature estimates are still uncertain. Does that axis run from a roof window at (370, 250) to the front at (440, 275)? The car appears diagonal; another estimate places its top or back at (425, 245) and its front at (350, 310). I am unsure of the slope. Its upper outline might run from a left-top point at (350, 250) to a right-top point at (445, 235). I could inspect a crop with a coordinate grid. My current reading places the windshield at (375, 265), the rear window at (435, 250), and the front hood at (350, 310). Using rear point (430, 245) and front point (350, 305), the long-axis image vector is roughly (-80, +60) pixels. A perpendicular closing direction would be approximately (60, 80), with image slope +1.3. The jaws currently close horizontally along image X. That might still grip diagonally across the roof, but rotating the gripper seems better. I need to determine the image-to-world directions before choosing the sign of the rotation about world Z. The downward orientation puts local Y along world -X, but does image right correspond to world -X or +X? The estimated car X coordinate, 0.332 m, is greater than the end effector’s 0.295 m, and its image X coordinate, 390 pixels, is greater than 320 pixels. This suggests image right corresponds to world +X. The car’s Y coordinate, -0.165 m, is less than the end effector’s -0.084 m, toward the front. Its image Y coordinate is 295 pixels, whereas the axis projection at z = 0.79 m may be around 180 pixels. This suggests image down corresponds to negative world Y, and image up to positive world Y. The front-to-rear image vector (+80, -60) therefore suggests a world direction toward +X and +Y. If I approximate the long-axis direction as (+0.8, +0.6), a perpendicular closing direction is (-0.6, +0.8), using (-dy, dx). The current closing direction is local Y along world -X, at 180°. The desired direction has angle atan2(0.8, -0.6) = 127°, a difference of -53°. Rotating the downward gripper by -53° about world Z would change the closing angle from 180° to 127° while leaving local X pointing downward. I can calculate the right orientation as Rz(-53°) multiplied by the current downward orientation. For the small bunny, I can keep the left gripper’s downward orientation. Closing along world X may suit its body width if its length runs along world Y. I’ll first align both arms at a safe height. The proposed right rotation is 0.925 rad, below the 1.0 rad limit, and the position target is within the distance bound. The left orientation will remain unchanged. Ten control steps may only partially complete the rotation and translation; I can refine the alignment afterward. I’ll calculate the right gripper quaternion now.

The quaternion multiplication checks out. SciPy uses xyzw order, so the downward quaternion is [-0.5, 0.5, 0.5, 0.5]. Applying a -53° rotation about world Z gives approximately [0.6706, -0.2244, 0.6706, 0.2244] in wxyz order. Does this still leave local X pointing downward? Yes, rotating about world Z preserves the -Z direction. For the next action, I’ll target the left link6 at (-0.18, -0.085, 1.04) m with the downward orientation, and the right link6 at (0.332, -0.165, 1.04) m with the orientation rotated by -50° about world Z. I’ll use 10 control steps.

The car appears rotated in the right-wrist image as a result of the gripper rotation. Is its long axis now roughly vertical? I estimate the roof center at pixel (290, 160), with the wheels on the right. The open fingers may appear diagonal, with black fingers along the lower left and right edges. I intended to align the closing direction across the car’s width. Its long axis now appears vertical while the jaws close horizontally in the image; the wrist camera rotates with the gripper, so the jaws remain horizontal in that view. I’ll use car-center pixel (290, 150), slightly left of the jaw axis. The bunny’s center in the left-wrist view appears near pixel (345, 170), but where does the gripper axis project at object height? I should use the current calibration to inverse-project the wrist-image points and refine the world-position targets. The bunny’s surface may be at z = 0.79 m. I estimate its height at about 0.065 m, the table at z = 0.75 m, and the body-center grasp height at z = 0.775 m. With the current left link6 height of 1.04 m, the axis projection at z = 0.78 m may be near image y = 174 pixels, similar to the earlier calculation. Bunny-center pixel (345, 165) suggests a positive world-X offset of about 0.005 m and perhaps world y = -0.08 m. I can inverse-project it at z = 0.78 m. For the car, I’ll use an estimated roof height of z = 0.79 m and center pixel (290, 150). The right gripper has not reached its final target quaternion, but inverse projection with the current calibration accounts for its current orientation. I’ll calculate the object positions and the axis projections at z = 0.78 m.

I initially considered the bunny’s body midpoint at wrist-image pixel (340, 180). Its head and body together span approximately image y = 100–235 pixels, with an overall center near y = 165 pixels. The larger lower body segment is centered around (345, 180), while the upper head segment is around (340, 130). Grasping across the body at (345, 180) seems appropriate. Assuming a surface height of z = 0.78 m, with the body top perhaps at z = 0.80 m, I estimate horizontal world coordinates of (-0.171, -0.102) m. My initial left target of (-0.18, -0.085) m was about +0.017 m off in Y. I’ll use (-0.172, -0.10) m instead. The car’s roof center is near wrist-image pixel (290, 160). At an estimated roof height of z = 0.79 m, its horizontal world coordinates are approximately (0.319, -0.161) m. I’ll target x = 0.319 m rather than the current 0.332 m, with y = -0.161 m. The right gripper still needs to finish reaching the orientation rotated by -50° about world Z. For this three-step alignment action, I’ll target left link6 at (-0.172, -0.10, 1.01) m and right link6 at (0.319, -0.161, 1.01) m, keeping both grippers open. I expect an actual descent of about 0.02 m, then further descents through link6 heights of 0.98, 0.95, and 0.925 m. I considered a final bunny grasp height of link6 z = 0.925 m. With its body top around z = 0.81 m, bottom around z = 0.75 m, and intended grasp contact around z = 0.775 m, I’ll instead use a final link6 height of 0.92 m. The fingertip height is link6 z minus 0.1576 m; at 0.92 m, the tip would be around z = 0.762 m, which seems suitable. For the car, I’ll use a final link6 height of 0.915 m for a lower grip. The left gripper’s open gap seems sufficient for the small bunny body, and the rotated right gripper’s maximum opening may be wide enough for the car’s approximately 0.05 m width. I’ll now execute the three-step alignment action.

I estimate the right gripper’s remaining orientation error relative to its target at about 0.37 rad. Another three control steps should finish the rotation. The left arm’s measured horizontal position is (-0.174, -0.094) m rather than the target (-0.172, -0.1) m, but it is close. The bunny’s center appears near wrist-image pixel (335, 165). Where does the current gripper axis project at z = 0.78 m? I expect any alignment correction to be minor. The car’s center appears near right-wrist pixel (315, 150), which looks well aligned. I’ll descend both link6 targets to z = 0.99 m and continue finishing the right gripper’s rotation over three control steps.

The right link6 has only descended to z = 1.001 m because the rotation is consuming control steps; that is acceptable. I’ll use another three control steps to target right link6 z = 0.96 m with the final orientation, which should finish the rotation and continue the descent. I’ll target left link6 z = 0.963 m in the same action.

The right gripper’s orientation is nearly at its final target. The car’s body appears centered near right-wrist pixel (330, 200), and the bunny near left-wrist pixel (330, 230), with the open fingers visible at the edges. Is the car slightly offset from the jaw axis in X? The right link6 target is x = 0.319 m and its measured position is x = 0.320 m, which seems close enough. I’ll lower the left link6 target to z = 0.936 m and the right to z = 0.94 m over three control steps, keeping both grippers open.

At the left link6 height of 0.937 m, the bunny gripper’s fingertips are at z = 0.7794 m, within the bunny body’s estimated z = 0.77–0.81 m. This seems suitable, though lowering to a final link6 height of 0.925 m may improve the grasp. The right link6 is at z = 0.942 m, putting its fingertips at z = 0.7844 m, near the car roof at approximately z = 0.79 m. That contact is high, so I’ll lower the right link6 to 0.915 m as planned, a descent of 0.027 m. I’ll lower the left link6 to 0.925 m, a descent of 0.012 m. I’ll use three control steps for this final descent.

The measured right link6 height is 0.923 m. Its orientation may have changed slightly because of the precheck, although I am unsure. The measured wxyz quaternion [0.667, -0.239, 0.662, 0.245] is close to the requested orientation. Both grippers are still open. Has the car’s center shifted to image x = 400 pixels? Its roof and body appear nearer (330, 400) pixels, with the wheels on the right. I wondered whether this gripper orientation might close along the car’s long axis. However, the two visible wheels are on the right, one above the other, with the axles forming a vertical line. This suggests the car’s long axis is vertical in the image and its width is horizontal, so the closing direction seems appropriate. At the current heights, I estimate the right fingertips at z = 0.765 m, suitable for contact with the car’s lower body, and the left fingertips at z = 0.767 m, which also seems suitable. I’ll close both grippers for three control steps while holding their poses steady, then perhaps allow another three steps of closure.

After three control steps, the gripper opening commands are 0.329 on the left and 0.414 on the right. Are the fingers now making contact? The left black pads appear to be along the bunny’s sides. On the car, the left pad appears at the roof or hood edge and the right pad near a wheel, which looks suitable. I’ll hold both poses steady and continue closure for another three control steps to let it plateau, then perform a test lift.

The opening commands have plateaued. I’ll make a test lift over three control steps, targeting left link6 z = 0.955 m and right link6 z = 0.953 m, then check whether the bunny and car move with their grippers.

Are both objects held securely? In the wrist view, the bunny stays the same size, with its top at y = 120 pixels both before and after the lift. The car has shifted or rotated relative to the gripper but remains between the jaws. The right opening command has decreased to 0.358, which could mean closure is still progressing or the car is slipping. In the head view, the bunny remains near y = 235 pixels, showing little movement. I estimate the car at pixel (480, 260), but did it move +15 pixels in X from (482, 263)? I considered a larger lift straight to link6 transport height z = 1.07 m over six control steps, then inspecting for slipping. The previous car fell during horizontal transport after reaching z = 1.04 m, so that grasp may not have been stable. The lower grasp this time should be better, but I should check that the opening command has plateaued before transport. The left opening command is stable at 0.282, while the right is now 0.358 after the lift and may still be changing. Holding briefly might let the grip settle, although the car could also be slipping slowly. I’ll keep both poses fixed and both grippers commanded closed for another three control steps, then inspect the opening commands before lifting farther.

The opening commands have plateaued, and I consider both grips stable. I’ll lift both link6 targets vertically to z = 1.07 m over six control steps; the left target requires a 0.116 m rise. The actual rise may be only about 0.05 m, so eight steps might be needed. I’ll request six steps first and inspect the resulting observation.

Both grips appear stable, so I should transport the objects to their baskets while retaining the right gripper’s rotated orientation. For the bunny, the grasp link6 height of 0.925 m and estimated table height of 0.75 m give an object-bottom offset of -0.175 m. At the current link6 height of 1.023 m, its bottom is approximately at z = 0.848 m, just above the rim. For the car, the grasp height of 0.923 m gives a bottom offset of -0.173 m; at the current link6 height of 1.017 m, its bottom is approximately at z = 0.844 m. I judge these heights sufficient to begin horizontal motion. I considered intermediate link6 targets of (-0.26, -0.02, 1.06) m for the left arm and (0.30, -0.02, 1.06) m for the right, estimating both moves within about 0.13 m. The eventual left basket target would have x = -0.28 m and y = 0.006 m. However, a direct move to y = 0.006 m and z = 1.0 m might pass the precheck and avoid the higher reach. From the current left pose of (-0.173, -0.103, 1.023) m to (-0.28, 0.006, 1.0) m, I estimate a distance of 0.153 m; from the current right pose of (0.319, -0.164, 1.017) m to (0.28, 0.006, 1.0) m, the distance is about 0.175 m. The earlier precheck from y = -0.035 m toward y = 0.04 m at z = 1.0 m failed with about 9 mm of position error, but I expect the nearer target at y = 0.006 m to pass. At placement, I estimate the object bottoms around z = 0.825 m, below the rims but above the floors. During the slight descent toward the baskets, their bottoms should remain above z = 0.82 m, while the remaining table objects’ tops are below z = 0.82 m. I judge that clearance just sufficient. The right car’s path moves toward positive Y with decreasing X and should avoid the watch near (0.17, -0.21) m and the green car at x = 0.08 m. The bunny’s path toward x = -0.28 m, with y moving from about -0.1 m to 0.006 m, could pass over the left watch near (-0.26, -0.1) m. Its bottom would descend from about z = 0.85 m to 0.825 m, remaining clear of the watch’s estimated height of z = 0.79 m. I’ll try the direct basket targets at y = 0.006 m and z = 1.0 m for 12 control steps, keeping both grips closed and preserving their orientations. The right gripper still points downward, but its different roll could affect the precheck; I think it will likely be acceptable. If the precheck fails, I’ll adjust the targets.

The bunny’s head is visible upright in the left-wrist view, and it appears stably held over the white basket. Could it be near the basket’s front-right edge? In the head view, I estimate the bunny at pixel (198, 175), above the previously placed elephant at (209, 174), while the white basket’s horizontal center is around 192 pixels. I judge this placement acceptable. The left link6 height is z = 0.999 m, and I estimate the bunny’s bottom at z = 0.824 m, within the basket, so I’ll release it. The yellow car appears at head-camera pixel (465, 192), over the red basket’s front rim. After 12 steps, the right link6 is still at y = -0.049 m rather than the target y = 0.006 m. Could its reach be constrained by the rotated orientation? The car still appears held, with an opening command of 0.332. I estimate its bottom at z = 0.826 m; the red basket’s front rim is around y = -0.04 m and z = 0.84 m. The car’s center may be slightly forward of the gripper and could still be just outside the basket’s front, so I need to advance it to y = 0.006 m before releasing it. I considered six more steps for the right arm, but I’ll use five toward the target position (0.28, 0.006, 1.0) m, retaining its orientation and closed grip. I estimate the remaining distance at about 0.055 m. At the same time, I’ll hold the left arm at its current pose and open its gripper. This may complete the bunny placement while the right arm finishes moving into the red basket.

The right gripper’s opening command is 0 again, and I take this to mean the car has dropped. This time, its head-camera position is approximately (465, 193) pixels, near the red basket’s front rim or interior. Is the yellow car within the red outline? I need to see whether it settles inside or falls outside. In the right-wrist view, the car is at the lower right while the basket occupies the upper and left portions, so it might be on the front wall or on the table outside. Another head-camera estimate places the car at (465, 191) pixels. The basket’s front face spans image y = 190–210 pixels, and the car’s center near y = 193 pixels suggests it may be sitting on the rim or just behind the front wall. A stable position inside the basket’s front portion would be acceptable. I considered retracting the left arm while opening and holding the right gripper, but opening or retracting the empty right gripper could disturb the car if it is on the rim. I’ll instead hold both arms and wait 10 control steps to let the physics settle, then inspect whether the car is inside or outside. The bunny has been released and is supported; the car still appears to be falling or settling, so robot_wait is appropriate here.

The right gripper’s opening command is now 0.059 after the wait, despite the earlier closed command. Does waiting preserve the gripper’s opening state, or might interpolation toward 0 continue? The car appears stable in the same position and may be lying partly inside the red basket. I should check its location geometrically using the current head and wrist views. I estimate the car’s center at head-camera pixel (465, 193) and right-wrist pixel (480, 330), although the fingers may partially occlude it. Triangulating these points could show whether it is within the red basket’s boundaries. Could it instead be resting on the table around world y = -0.05 m? At an assumed height of z = 0.78 m, head-image v = 193 pixels might correspond to world y around 0.06 m. I’ll inverse-project the head point at z = 0.75 m and 0.78 m to check. My earlier estimate for the basket’s front rim was image v = 192 pixels at world z = 0.83 m and y = -0.013 m. At z = 0.78 m, v = 193 pixels might instead give y around 0.05 m; this needs calculation. I estimate the red basket’s Y extent as approximately [-0.04, 0.13] m, with its floor at z = 0.75 m. If the car’s center is at y = 0.04 m and z = 0.78 m, it would be inside above the basket floor. Its head-image v = 193 pixels is much higher in the image than the table objects near v = 250 pixels, suggesting it is farther back inside the basket. The earlier fallen car outside the basket was near v = 252 pixels. This makes an interior placement seem likely, although it could still be on the front rim, which appears near v = 190 pixels at z = 0.84 m. Another tentative estimate, using car-center z = 0.78 m and v = 193 pixels, gives y = 0.057 m, also inside. I’ll calculate and triangulate rather than rely on these estimates. In the right-wrist view, the basket fills the upper-left area and the car is toward the lower right. If the car is inside near the front wall, its world Y coordinate might be around -0.02 m, compared with the gripper’s y = -0.027 m. The camera offset may explain this appearance. Another possible center correspondence is head pixel (463, 191) with wrist pixel (500, 310), but occlusion and mismatched points could produce triangulation error. I could use the distinctive black knob on the car’s roof instead. It may be at head pixel (470, 192) and wrist pixel (455, 335). Is the roof knob actually visible in the head view? My revised estimates put it around head pixel (470, 190) and wrist pixel (455, 330). I’ll triangulate that correspondence.

The triangulation suggests the car is around z = 0.86 m and y = -0.05 m, perched on the front rim, which I estimate at z = 0.84 m and y = -0.04 m. The head view also appears to show it on the rim rather than resting on the basket floor. Native containment may require the object to be inside the basket volume, so a rim placement might not count. I should nudge it inward or regrasp it and place it farther along +Y. The right link6 is currently at (0.28, -0.027, 1.0) m. With the rotated orientation still pointing local X downward, I estimate the fingertips at z = 0.842 m and approximately the same horizontal coordinates, (0.28, -0.027) m. Is the empty gripper closed around the car? The car appears just below and forward of it, and the opening command is 0.059. I considered opening the gripper and moving slightly along +Y while lowering, but a closed finger might gently push the car inward over the rim instead of requiring a full regrasp. I interpret the fingertips at y = -0.027 m as being behind the car center at y = -0.05 m, suitable for a push toward +Y at around z = 0.85 m. One option is to move +0.05 m along Y while holding link6 at z = 1.0 m, keeping the fingertips around z = 0.842 m. That would give a target y = +0.023 m. It may be reachable, though it could be near a reach limit with the current orientation rolled by -50°. The arm previously reached y = -0.025 m without reaching its target of y = 0.006 m; was that related to the car dropping? I think the new precheck would likely pass, but this remains uncertain. I need to be cautious because the fingers could contact the red basket’s rim at z = 0.84 m. The intended contact is to push the car into the interior without displacing the basket. Are the baskets fixed? They appear static, but they might be movable and heavy. I considered a gentle three-step push to right link6 position (0.28, 0.005, 1.0) m with the gripper closed, possibly while retracting the left arm. I’ll instead hold the left arm to avoid simultaneous unexpected motion. If the car is already inside, I expect the nudge simply to move it farther inward. Because this is contact motion near the basket, I’ll start with only two control steps toward right link6 y = -0.005 m, a planned +0.022 m change. I’ll keep the right arm’s current orientation and closed-gripper command, and hold the left arm stationary with its gripper open.

The car moved left in the head-camera image, from x = 465 to x = 459 pixels. It may still be on the front rim, though perhaps the nudge pushed it inward. Its center now appears near (460, 189) pixels, farther inside the red basket’s front area. The right gripper’s opening command unexpectedly increased to 0.106 despite being commanded closed. I interpret this as contact with the car, with the opening increasing because of the collision, and therefore as useful pushing contact. I’ll continue the inward push for three control steps to try to move the car off the rim. The right link6 is currently at y = -0.017 m; the target is y = +0.005 m, a planned change of +0.022 m.

The yellow car now appears inside the front-left of the red basket. Its head-camera center is around pixel (456, 184), within the estimated red interior spanning image x = 390–500 and y = 150–200 pixels, so I consider it inside. I interpret the right opening command of 0.213 as evidence of pushing contact. I should retract the right arm carefully upward and back while leaving the car in place. There appear to be four objects remaining: the first elephant, the left watch, the green car, and the right watch. The yellow car is in the red basket, and the bunny and second elephant are in the white basket. I can use the left arm for the remaining elephant and left watch, and the right arm for the green car and right watch, working in parallel where their paths are separate. I’ll approach the first elephant near world horizontal coordinates (-0.37, -0.11) m and the green car near (0.075, -0.14) m. The left link6 is currently at (-0.277, -0.001, 0.999) m with its gripper open. A target above the elephant at (-0.37, -0.11, 1.04) m is approximately 0.158 m away. The current fingertips are around z = 0.841 m, just above the rim. Moving forward along negative Y and leftward takes the gripper away from the basket; it could clip the front rim if it stayed at its initial height, but the target raises link6 by 0.041 m, so I expect clearance. A safer alternative would be an intermediate left pose at (-0.32, -0.06, 1.07) m before the final approach. The right link6 is at (0.278, -0.004, 0.997) m, with the gripper commanded closed and apparently contacting the car. I need to open it and withdraw upward and back to avoid further pushing or clamping. One option is to lift to z = 1.07 m while moving to y = -0.04 m, then approach the green car. I could also move both arms together, using the left elephant approach target and an open right-gripper intermediate target at (0.20, -0.10, 1.07) m. The proposed right displacement is (-0.078, -0.096, +0.073) m, with length approximately 0.145 m. Opening during this upward and forward withdrawal might briefly contact the car before releasing it. Could spreading the fingers push it? The car appears stable inside, and the estimated basket width of 0.22 m seems sufficient for the fingers to open. At the intermediate target, the fingertips would be around z = 0.91 m, above the rim, so I judge this withdrawal safe. The left gripper can retain its downward orientation for the elephant. For the green car, I should adjust the right closing direction. The car’s long axis appears roughly horizontal in the head view, suggesting it runs along world X. Closing along world Y should therefore grip across its width; the current standard downward orientation closes along world X and would grip along its length, which seems less stable. Starting from the downward orientation with local Y along world -X, at an angle of 180°, I want local Y along world Y, at 90°. This calls for a -90° rotation about world Z: Rz(-90°) multiplied by the downward rotation. I tentatively expect a wxyz quaternion around [0.707, 0, 0.707, 0], or [0.70710678, 0, 0.70710678, 0], but I should calculate it exactly. The current right orientation corresponds approximately to Rz(-50°) multiplied by the downward rotation, so the additional rotation to -90° is -40°, or about 0.698 rad, below the 1.0 rad command limit. I can request this orientation directly at a safe height. With that orientation, the car should appear vertical in the wrist view. Rather than using the right intermediate pose, I could approach the green car directly. Using its estimated horizontal position (0.077, -0.14) m, a right target at (0.077, -0.14, 1.04) m gives a displacement of (-0.201, -0.136, +0.043) m and a distance of approximately 0.246 m, just below the 0.25 m limit. The precheck might fail because this is near the left side of the right arm’s workspace, although I believe x = 0.077 m is within reach. The path starts above the red basket and moves forward and left over the table, near the blue basket. I expect the fingers to remain above the rims and judge the path clear. A direct approach with the -90° orientation over 12 control steps would save an intermediate move; the estimated orientation distance is about 0.7 rad, below the 1.0 rad limit. I’ll plan open-gripper targets at (-0.37, -0.11, 1.04) m for the left arm and (0.078, -0.14, 1.04) m for the right arm, with the right orientation rotated by -90° about world Z, over 12 control steps. First, I’ll calculate the exact right quaternion.

The calculated right-gripper quaternion is approximately [0.707, 0, 0.707, 0] in wxyz order, corresponding to Rz(-90°) multiplied by the downward orientation. Its local X direction looks correct. I’ll issue the planned approach action with both grippers open for 12 control steps.

The right arm has not reached its target, perhaps because it still has farther to travel. After 12 control steps, its measured link6 position is (0.219, -0.04, 1.013) m, still near the red basket, rather than the target horizontal position of (0.078, -0.14) m. Its gripper is open, and the yellow car remains inside the basket. I’ll allow another 12 steps toward the green car while beginning the left arm’s alignment and descent. In the left-wrist view, the elephant’s center appears near pixel (340, 190), with the watch to its right. I estimate the elephant’s body center more specifically at (340, 185). The current left link6 position is (-0.368, -0.107, 1.04) m. Where would the gripper axis project at z = 0.80 m? I could use inverse projection to refine the center. Earlier triangulation placed this elephant’s center at approximately (-0.37, -0.114, 0.798) m, so the current horizontal alignment looks good. A possible body-grasp position is (-0.37, -0.115) m in X and Y. I initially considered a three-step left approach to (-0.37, -0.115, 1.0) m, followed by descents to link6 heights of 0.97 m and 0.94 m. The right target remains (0.078, -0.14, 1.04) m with the downward orientation rotated by -90° about world Z. I estimate its remaining distance at about 0.18 m; another 12 steps may reach it. Could I use a 12-step action for both arms while lowering the left? The grasp instructions call for only one to three steps per action. However, I expect the left arm to reach this approach target within three steps and then remain there while the right continues moving. Waiting until the end of 12 steps to inspect would miss any intermediate contact, but the left target height of 1.0 m should still be safely above the elephant, with the fingertips at approximately z = 0.842 m. I consider this an approach motion rather than a motion near contact. I’ll use 12 steps, keeping both grippers open, lowering the left only to that approach height and continuing the right toward the green car.

The green car’s center appears near pixel (425, 270) in the right-wrist view. The right link6 is currently at horizontal coordinates (0.149, -0.089) m, with a target of (0.078, -0.14) m, leaving approximately 0.08 m to travel. The car’s long axis appears vertical in the image, so horizontal jaw closure looks appropriate. The elephant’s center appears near pixel (345, 220) in the left-wrist view. With left link6 at z = 1.0 m and an assumed object height of z = 0.8 m, might the gripper axis project near image y = 255 pixels? Perhaps I should adjust the left target to world y = -0.12 m. I’ll use the current wrist-camera calibration to inverse-project the elephant’s saddle center at pixel (345, 215), assuming z = 0.80 m, and the green car’s roof center at pixel (425, 270), assuming z = 0.79 m. I also want to check the current gripper-axis projections at object height to refine the alignment.

The elephant’s grasp center may be the saddle center at wrist-image pixel (350, 220), with estimated world horizontal coordinates (-0.361, -0.123) m. Compared with the current left link6 coordinates of (-0.37, -0.115) m, this calls for corrections of +0.009 m in X and -0.008 m in Y. I estimate the green car’s horizontal center at (0.094, -0.138) m, so I’ll use target X = 0.094 m rather than 0.078 m. Its original head-image X coordinate was 357 pixels, giving world X around 0.08 m at z = 0.75 m and around 0.075 m at the assumed roof height of z = 0.79 m. The wrist inverse projection instead gives X = 0.096 m at image x = 425 pixels; perhaps my manual center estimate is off. The car appears to span image x = 365–480 pixels, with a center at 422.5 pixels, which supports the estimate near 0.096 m. I’ll use the right link6 target (0.094, -0.138, 1.01) m. The left target will be (-0.361, -0.123, 0.97) m, combining alignment with a 0.03 m descent over three control steps. I estimate the right move as 0.059 m and think three steps may suffice. I’ll command both targets for three steps with the fingers open.

The right link6 is still at horizontal coordinates (0.113, -0.12) m and has not reached its target. The green car’s center appears near pixel (365, 220) in the right-wrist view, so I should continue correcting the alignment as the arm moves. The elephant appears well centered near pixel (330, 240) in the left-wrist view. I’ll lower the left link6 target to z = 0.943 m and move the right link6 toward (0.094, -0.138, 0.98) m over three control steps.

The green car appears well centered near wrist-image pixel (340, 220). The left elephant’s saddle and body center may be near pixel (330, 300). I am still unsure where the gripper axis projects at object height z = 0.8 m with link6 at z = 0.944 m, but I consider the horizontal target from the previous alignment acceptable. Should I lower the left link6 to z = 0.925 m? The elephant’s top is around z = 0.82 m, and I estimate the fingertips at 0.944 - 0.157 = 0.786 m, already within the body’s height. A final link6 height around 0.93 m might suffice. The previous grasp of the second elephant at z = 0.937 m succeeded. This elephant seems similar in size, perhaps slightly smaller, so I’ll use z = 0.935 m. The right link6 is at z = 0.988 m, with the fingertips around z = 0.830 m and the green car’s roof around z = 0.79 m. I need to descend toward link6 z = 0.918 m for a lower grip. I’ll first target left z = 0.935 m and right z = 0.95 m for three control steps, then lower the right toward 0.918 m.

In the left wrist view, the open fingers are at image x = 120 and 520 pixels. At the contact region around image y = 400 pixels, the elephant spans x = 200–510 pixels. Its right side is almost against the finger, but I judge closure acceptable. In the right wrist view, the green car spans image x = 250–410 pixels, leaving ample space within the open gripper gap. The left link6 is at its final grasp height of z = 0.935 m, so I can hold it there and close the left gripper while the right arm finishes descending. The two arms can proceed through their grasp stages independently, so I’ll combine three steps of left-gripper closure with three steps of open-finger descent on the right. I’ll target right link6 z = 0.918 m and expect its actual height after this action to be around 0.924 m.

The left gripper is still closing, with an opening command of 0.379 and the elephant between its fingers. The right link6 is at z = 0.923 m, close enough to the intended grasp-height target of 0.918 m. The car’s roof appears very large in the wrist view, with the open fingers at the edges. I’ll hold both poses steady and command both grippers closed for three control steps, continuing the left closure and beginning the right closure.

The left elephant has rotated significantly in the gripper, leaving its saddle diagonal, but it still appears held. The right car appears stable. The opening commands are 0.306 on the left and 0.371 on the right. I could immediately make a three-step test lift to left link6 z = 0.965 m and right link6 z = 0.953 m. The fingers might continue closing during the lift, but the contacts look good. However, the previous procedure allowed another three steps of closure before lifting. With 876 control steps remaining, I have enough budget to let the grips settle first. I’ll hold both poses fixed and continue closure for three steps, then make a three-step test lift.

Both grips appear stable. I’ll make a vertical test lift over three control steps, targeting left link6 z = 0.965 m and right link6 z = 0.953 m, then verify that the elephant and green car stay fixed between the pads.

The green car may have rotated upward: its front hood is now at the top of the wrist view, but it remains between the pads. In the head view, it appears near pixel (350, 249), slightly lifted and stable. I am less certain about the elephant. It appears near head-camera pixel (130, 240), compared with its original position at (139, 239), showing mostly a horizontal shift. The left link6 rose from z = 0.935 m to 0.963 m, a measured increase of 0.028 m. If the elephant moved with it, I would expect about 15 pixels of upward motion, yet its image v coordinate remains around 240. Could the gripper be dragging or rotating it on the table rather than lifting it? The opening command of 0.306 could indicate contact without enough friction to lift. Perhaps this wooden elephant is larger or heavier, or the fingers are too high and sliding. The previous elephant lifted successfully with the same strategy at link6 z = 0.937 m. A larger lift, as before, would help verify this grasp. My estimated head-camera center was (139, 239) originally, (132, 240) after closure in obs_000224, and (128, 240) in obs_000230. That suggests leftward motion rather than upward motion. Could the held object's bottom have a different offset from link6, perhaps be at z = 0.82 m rather than at table height? It was originally on the table, so a 0.028 m lift would put its bottom at z = 0.778 m, and its head-camera projection should change. Perhaps rotation made it stand taller or changed its centroid enough to compensate in the projection. The wrist view provides stronger evidence of a grasp. The elephant changed from diagonal to vertical, but it has not translated vertically relative to the camera. Between obs_000227 and obs_000230, its tail top remains at image y = 80 pixels, and its body at y = 300 pixels still spans x = 210–540 pixels. If the elephant stayed on the table while the downward-facing wrist camera rose by 0.028 m, I would expect an obvious size decrease of about 10%. I do not see that decrease. I therefore conclude that it is moving with the camera and is held, despite the uncertain head-view projection. Before transport, I need clearance above the nearby watch at approximately x = -0.26 m, y = -0.1 m. The large elephant could hit it while moving toward the white basket at x = -0.28 m, y = 0.006 m if its bottom remains low. I initially considered lifting the left link6 to z = 1.06 m and the right to 1.05 m. The green car will go to the red basket at x = 0.28 m, y = 0.006 m; its current right link6 position is (0.094, -0.138, 0.952) m. I’ll instead target z = 1.07 m for both arms over six control steps, expecting actual heights around 1.02 m, then move directly toward release poses at z = 1.0 m as before. The car has rotated in a way that makes its grasp look somewhat uncertain, but its opening command is stable. The lower grip across its width should hold. I could place it slightly farther inward at y = 0.01 m to avoid the rim. Its current orientation uses the downward pose rotated by -90° about world Z; that may affect reach, but y = 0.006 m at z = 1.0 m is likely reachable. With an estimated car-bottom offset of -0.173 m from link6, link6 z = 1.02 m would put its bottom at z = 0.847 m. For now, I’ll lift both arms vertically toward z = 1.07 m for six steps, keeping their grips and orientations steady.

The head view now clearly shows the left elephant lifted near pixel (110, 220) and the green car lifted near (360, 235). Has the car rotated to nearly horizontal in the right-wrist image, and is it being held by its front and back? It appears to have pitched vertically, with its roof now on the side, but it remains stable between the fingers and the right opening command is 0.37. It could drop as before, though I expect it would land inside the basket if I move it far enough inward. I should use release points farther inside, at y = 0.02 m. During the previous yellow-car placement, the right arm only reached y = -0.025 m toward a target of y = 0.006 m before the car dropped onto the rim. A right target at y = 0.02 m and z = 1.02 m might be reachable. Could the right orientation rotated by -90° allow more reach than the earlier -50° orientation? I estimate a workspace limit around y = 0.03 m at z = 1.0 m. I’ll try y = 0.02 m at z = 1.02 m and lower the car only after reaching that position. The direct right-arm move from (0.096, -0.141, 1.021) m to (0.28, 0.02, 1.02) m has an estimated length of 0.243 m, below the 0.25 m command limit. The left-arm move from (-0.361, -0.126, 1.031) m to (-0.28, 0.02, 1.0) m has an estimated length of 0.169 m. Could the right path pass above the blue and red baskets? Its X coordinate moves from approximately 0.096 m to 0.28 m and its Y coordinate from approximately -0.14 m to 0.02 m. I am unsure whether it passes over the blue basket’s right edge near x = 0.14 m, y = 0.06 m. The held car’s bottom is estimated at z = 0.848 m, just above the rim at z = 0.84 m, so I judge the path acceptable. I’ll use the maximum 15 control steps, which may be enough to reach the targets. The left target at z = 1.0 m is a release pose; the right target at z = 1.02 m keeps the car higher for transport before lowering it. If the car drops near the end of transport around y = 0 m, I expect it to fall inside. The left arm may arrive first and hold while the right continues. I’ll keep both grips closed and inspect the next observation before releasing the elephant.

The green car has dropped again, but the head view shows it near pixel (427, 205), apparently in the red basket’s front-left interior. In the right-wrist view, it is near the bottom-right beside the red front wall. Could it be perched on the front rim? It appears vertical against the wall in the head view, while the yellow car is near pixel (420, 180). The green car’s visible bottom is at image y = 216 pixels, compared with the basket’s front bottom at y = 210 pixels, so it could be hanging outside the wall. I still need to determine whether it is contained. The green car fell when the right link6 was at (0.257, -0.01, 1.015) m, compared with (0.279, -0.025, 1.0) m for the yellow car’s earlier drop. I estimate the green car’s position at approximately x = 0.23 m, y = -0.02 m, z = 0.8 m, which would put it in the basket’s front half. Using its estimated head-image center at pixel (427, 203), inverse projection at z = 0.78 m gives approximately x = 0.235 m and y = 0.037 m, inside the basket. If it is on the rim at z = 0.84 m, I estimate x = 0.198 m and perhaps y = -0.008 m. That is still within the basket’s estimated X extent of [0.14, 0.42] m, and I consider y = -0.008 m inside. It therefore seems likely to be inside even if it is resting on the rim, and the native containment check might count it. I’ll release the remaining elephant into the white basket first, then assess the green car after it settles. The left link6 is at (-0.288, -0.001, 0.999) m, and the elephant appears within the white basket near head-camera pixel (174, 176). It overlaps the other elephant in the image, but I judge that the container can hold both. I’ll open the left gripper for three control steps while holding the right arm stationary with its gripper commanded closed. Afterward, I’ll inspect the green car and only nudge it if it is clearly outside.

The green car has settled outside the red basket again and now appears flipped on the table at head-camera pixel (420, 242). It slipped before the arm moved far enough over the basket, so I need another recovery grasp and a better transport strategy. Could the repeated rotation and slipping be caused by the car’s shape, the right gripper’s orientation, or insufficient closure from the controller? It stays engaged during lifting, then slips during horizontal motion as the opening command gradually reaches 0. I considered using the left arm, shortening the transport, or using both hands, although two hands do not seem necessary. Pushing it along the table into the red basket would be blocked by the basket wall. The left arm is currently at its basket, and the right arm can still recover the car. The green car’s length runs along world X, and I grasped its body across its width by closing along world Y. Did it pitch by 90° around the closing axis during the lift? In the wrist view from obs_000236, its front was up and its back down, suggesting rotation around the horizontal image X axis, which was the closing direction. Contact at the sides with the center of mass below does not prevent that pitch, although I would expect it to remain stable. I attribute the eventual slipping to smooth pads. Gripping the front and rear along world X might provide more contact on their vertical surfaces and prevent pitch around world Y, though it could instead rotate around its length. The yellow car also slipped with a diagonal grasp across its width. A grasp along the green car’s length may not fit. I estimate its length at about 0.10 m and the maximum gripper opening at perhaps 0.09 m. I am unsure of the initial open gap or how an opening command of 1 corresponds to finger separation. If the maximum gap is 0.085 m, a 0.10 m length would be too large, whereas its approximately 0.05 m width should fit. A lower grasp across the width may be more effective. Lowering link6 to z = 0.90 m would put the fingertip at z = 0.742 m, below the estimated table height of 0.75 m and risking collision. At link6 z = 0.91 m, the tip would be at z = 0.752 m, about 2 mm above the table. The previous link6 height of 0.923 m put the tip at z = 0.765 m, contacting the upper 25 mm; lowering by 0.013 m could improve contact significantly. I plan to regrasp the green car at link6 z = 0.91 m. The car now appears upside down, possibly with its wheels up and its flat chassis on top. In obs_000254, I see what may be a black roof or chassis with green trim; the wheels may be hidden. Its height may now be only about 0.02 m. I could grasp its sides lower across the width without first turning it upright, since container placement has no orientation requirement. For a body height around 0.025 m, I considered fingertip height z = 0.76 m and link6 heights of 0.918 m or 0.91 m. Before recovering the car, I can handle the two remaining watches. One option is to pick the left watch while the right arm recovers the car, then pick the right watch. I prefer to pick both watches concurrently and place them in the middle basket, leaving the green car last so I can focus on its recovery. The left watch remains near head-camera pixel (197, 242), and the right watch near (408, 294). There are 846 control steps remaining, which should be enough. The watches have flat circular bands and may be difficult to grasp. I could close across the outer ring along a diameter, grip the band’s sides, or place one finger through the opening. A grasp contacting the watch case and band edge may be stable. With an estimated watch diameter of 0.045 m, the gripper should be able to contact opposite outer edges. The left watch’s ring is centered near head-camera pixel (196, 242), with its face to the right near (207, 243) and its band to the left. Its overall diameter appears to be about 30 pixels, perhaps 0.03 m. A grasp across the whole watch could work, although its center of mass may lie toward the face on the right. The right watch’s ring is near (408, 294), with the face perhaps below it at (408, 298) and the band above. Its overall image size is about 25 × 20 pixels, perhaps 0.03 m. Both watches should be graspable across their full shapes if the contact is low enough. Pinching only one band edge, with one finger inside the ring and the other outside, might be more secure, but the fingers are large relative to these small watches lying flat on the table. I expect a downward grasp on the band to be suitable. I can close along world X or Y, aligned through the face and band, after refining the center and height. I estimate the table at z = 0.75 m and the band height at 0.01–0.02 m. A final link6 height of 0.908 m would put the tip at z = 0.7504 m, nearly on the table. I prefer 0.914 m, putting the tip at z = 0.7564 m, to contact an object about 0.015 m thick without colliding. I also considered link6 z = 0.912 m, with the tip around z = 0.754 m. A measured height of 0.91 m would put the tip around z = 0.752 m, which I judge safe. The fingertips need to get close to the table to pick these flat objects. Using the head-camera centers at an assumed z = 0.76 m, I estimate the left watch near x = -0.269 m, y = -0.105 m, and the right watch perhaps near x = 0.171 m, y = -0.22 m. I’ll approach at link6 z = 1.0 m and refine from the wrist views. The right arm is currently at (0.257, -0.01, 1.015) m, closed and empty above the red basket. The left arm is at (-0.288, -0.001, 0.999) m, open above the white basket. My initial approach targets are (-0.268, -0.105, 1.0) m for the left arm and (0.17, -0.215, 1.0) m for the right. I considered using the standard downward quaternion [0.5, -0.5, 0.5, 0.5] in wxyz order for both, closing along world X. However, the right arm’s current orientation is the downward pose rotated by -90° about world Z. Comparing its approximate quaternion [0.707, 0, 0.707, 0] with the standard downward quaternion gives a dot product of 0.3535 + 0 + 0.3535 + 0 = 0.707, corresponding to an orientation distance of 1.571 rad. That exceeds the 1.0 rad limit and would require an intermediate orientation. I can instead retain the right arm’s current orientation, which closes along world Y. The right watch is roughly circular, with its face below the band, so closure along world Y should align with its band-and-face axis. The left arm’s standard downward orientation closes along world X, also along that watch’s band-and-face axis. This gives suitable alignment without rotating either arm. The right approach is approximately 0.223 m from its current pose, below the 0.25 m limit, and the left approach is approximately 0.105 m away. I judge the paths clear: the left move stays around link6 z = 1.0 m, with the fingertips near z = 0.842 m above the watch. The right move from the red basket toward y = -0.215 m has fingertips estimated near z = 0.857 m, clear of the green car on the table at about z = 0.78 m. I’ll move both arms toward the watches for 15 control steps with their grippers open, retaining their current orientations.

The left wrist view shows the watch’s circular band clearly, with the face toward the bottom-right. The left jaws currently close horizontally along world X, but the band-and-face axis appears vertical in the image. My earlier interpretation that the face was to the right in the head view may have been wrong. I had estimated it at head pixel (207, 243), but perhaps it is actually near (197, 249). With the downward wrist orientation, image X may correspond to world X and image Y to negative world Y, so a face toward the image bottom would lie toward world -Y and project lower in the head view. A grasp across any diameter might hold the whole watch, but its center of mass is toward the face at the bottom. Closing along the band-and-face axis seems better. The current horizontal closure could grip the ring’s sides while leaving the face free, allowing the watch to rotate. I’ll rotate the left downward orientation by -90° about world Z so the jaws close along world Y. The right gripper already has that orientation. The second watch is at the right edge of the right wrist view, so that arm still needs to move toward x = 0.17 m and y = -0.215 m. The green car appears large near the top center of that view and does not seem to interfere. The current left link6 position is (-0.269, -0.098, 1.001) m. I estimate the watch center at left-wrist pixel (330, 180), with a surface height of z = 0.765 m. Inverse projection would perhaps place its horizontal world coordinates near (-0.267, -0.104) m, which is close to the planned approach position. The full left rotation from the standard downward orientation to the -90° orientation is about 1.571 rad, so I need an intermediate orientation. I’ll first use the -45° orientation, approximately [0.653, -0.2706, 0.653, 0.2706] in wxyz order, with an orientation change of about 0.785 rad, then continue to -90°. For this action, I’ll keep the left gripper above the watch at z = 1.0 m while making the -45° rotation, and continue the right translation toward (0.17, -0.215, 1.0) m with its -90° orientation. Both grippers will remain open. I’ll request 12 control steps; the right arm may need more travel afterward, and the left rotation may still be partial.

Both watches are now visible. The left wrist has only partially rotated, by approximately -29°, and the watch face appears diagonally down and to the right. Would completing the -90° rotation make the face appear vertical? The right watch’s face appears to the right in its wrist image despite that wrist already having the -90° orientation, so my earlier assumption about the image axis was wrong. The wrist camera rotates with the gripper, keeping the jaws horizontal in the image. Horizontal closure therefore already runs through the right watch’s band-and-face axis. I expect the left watch’s face will also appear to the right after completing its rotation, as the camera rotates counterclockwise. I should finish the left wrist’s -90° orientation and refine both grasp centers. I estimate the right watch’s center at wrist-image pixel (340, 170), with the current right link6 position at (0.17, -0.215, 1.0) m. Where does its gripper axis project at z = 0.76 m? I’ll use inverse projection to refine the position. The left watch’s estimated center is at pixel (325, 165), with the current left link6 position at (-0.267, -0.105, 1.0) m and its rotation still approximately -29°. Completing that rotation will change the image coordinates, but the world target will remain the same. I’ll inverse-project the current left point (325, 165) and right point (340, 170), assuming z = 0.765 m for both watches.

I estimate the watches’ horizontal centers at (-0.266, -0.109) m on the left and (0.167, -0.221) m on the right. I’ll target link6 positions of (-0.266, -0.109, 0.98) m and (0.167, -0.221, 0.98) m, finishing the left wrist’s -90° orientation while keeping both grippers open. I initially considered six control steps. Is the left wrist’s remaining rotation about 0.9 rad, or approximately 1.06 rad from its estimated -29° orientation to -90°? Using the current wxyz quaternion [0.613, -0.352, 0.614, 0.351] and target [0.707, 0, 0.707, 0], I calculate a dot product of 0.433 + 0 + 0.434 + 0 = 0.867, giving an angle of 0.522 rad, below the 1.0 rad limit. At an estimated rotation rate of 0.075 rad per control step, three steps may be insufficient and about seven may be needed. I’ll use eight steps to finish the left rotation and descend 0.02 m. I expect the right arm to reach z = 0.98 m within three steps and then hold there. The fingertips would be around z = 0.822 m, above the watches, so I judge this approach safe.

Did my previous dot-product calculation mishandle the quaternion signs? Using the current and target quaternions, the dot product is 0.613 × 0.707 + (-0.351) × 0 + 0.613 × 0.707 + 0.351 × 0 = 0.8676. The orientation distance is 2 acos(0.8676) = 1.044 rad, slightly above the 1.0 rad limit. I need an intermediate orientation, either spherical interpolation with a fraction of 0.8 or a -75° rotation rather than going directly to -90°. Is the current rotation approximately -29°? That would leave 61° to the -90° target, or about 1.06 rad. I’ll use the downward orientation rotated by -75° about world Z, then continue to -90°. Its wxyz quaternion might be approximately [0.6845, -0.1305, 0.6845, 0.1305], but I should calculate it. I’ll compute candidate orientations at -65°, -70°, and -75°.

I’ll use the left wrist orientation rotated by -70° about world Z from the downward pose as an intermediate target. I estimate the remaining change at 41°, or about 0.72 rad, safely within the 1.0 rad command limit. I’ll keep the planned horizontal positions, target link6 z = 0.98 m for both arms, and leave the right orientation unchanged. Both grippers will remain open, and I’ll request six control steps.

After six control steps, I estimate the left wrist’s rotation about world Z from the downward pose at -44°, rather than the requested -70°. It moved from about -29° to -44°, a change of 15°. Why is the rotation progressing so slowly? I initially estimate that another 12 steps may be needed to reach -90°. For the current left quaternion and the -90° target, the dot product is 0.655 × 0.707 + (-0.267) × 0 + 0.655 × 0.707 + 0.266 × 0 = 0.926. I estimate the remaining orientation distance at 0.777 rad, below the 1.0 rad limit, so I can now command the -90° orientation directly. The right watch appears centered at wrist-image pixel (320, 170), and the left watch at (310, 170). The left arm’s current horizontal position of (-0.265, -0.109) m looks suitable based on the inverse projection. I’ll finish the left rotation while lowering both link6 targets to z = 0.96 m, keeping both grippers open. At that height, I estimate the fingertips at z = 0.802 m, 0.037 m above the watches’ estimated height of 0.765 m, so I judge the motion safe. I’ll use eight control steps for this action.

I estimate the left wrist’s rotation about world Z from the downward pose at -66°, leaving 24°, or about 0.42 rad, to the -90° target. The watch face now appears to the right, so the alignment looks good enough to finish the rotation while descending. The right watch is centered near wrist-image pixel (325, 200), with its face also to the right. I’ll lower both link6 targets first to z = 0.935 m, then to 0.915 m. At the current link6 height of 0.96 m, the fingertips are around z = 0.802 m and the watches around z = 0.765 m; I plan a total descent of 0.045 m. For this action, I’ll use three control steps with both grippers open, targeting z = 0.935 m for both arms and the -90° orientation for the left wrist. The actual heights may reach only about 0.938 m, with the left orientation still approaching its target.

The left watch appears about 190 pixels in diameter, compared with approximately 400 pixels between the gripper’s inner edges, so it fits within the open gap. I should lower toward link6 z = 0.915 m. The right link6 is currently at z = 0.936 m, putting its fingertip around z = 0.778 m; the watch top may be around z = 0.77 m, so the fingers are nearly at contact height. A three-step command toward z = 0.915 m might bring the measured height to about 0.918 m. For the left arm, moving from z = 0.941 m toward 0.918 m would require about 0.023 m of descent. Its orientation still has approximately 16° remaining to the downward pose rotated by -90° about world Z, which may consume some of the control steps. I’ll use three steps with both grippers open, targeting left link6 z = 0.918 m with that orientation and right link6 z = 0.916 m.

After three control steps, the right link6 height is 0.923 m rather than the target of 0.916 m, perhaps because the local IK is slowing near the table. The left link6 height is 0.924 m, and I estimate its wrist rotation about world Z from the downward pose at -81°, close to the -90° target. The watch bands appear large between the jaws. I estimate the left fingertips at z = 0.766 m and the right fingertips at z = 0.765 m, just above the estimated table height of z = 0.75 m. With the watches perhaps 0.012 m thick, these heights seem sufficient for contact. I considered descending farther, but I’ll close now to avoid risking contact with the table. The jaws close horizontally in each wrist image across the watch diameter. The left watch has its band clasp on the left and face on the right; the right watch also has its band on the left and face on the right. This looks like suitable alignment along each band-and-face axis. I’ll close both grippers for three control steps while holding their current positions and orientations.

Both watches are now clasped at their outer left and right sides, which looks good. The gripper opening commands are 0.411 on the left and 0.346 on the right. I’ll hold both poses steady and continue closure for another three control steps to let the grips settle, then make a three-step test lift.

Both watch grips appear stable. I’ll make a vertical test lift over three control steps, targeting link6 z = 0.954 m for both arms, then check that each watch moves with its gripper.

The measured left link6 height is only z = 1.008 m, compared with the target of 1.04 m. The incomplete motion may be related to the motion and orientation requirements or proximity to a reach limit. The left watch appears between the white and blue baskets at head-camera pixel (247, 195), with its bottom roughly at z = 0.84 m, so I judge it clear. The right watch remains stably held, and the green car is upright again on the table. I’ll move the left arm to the blue-basket release point at (-0.02, 0.006, 1.0) m, estimating the move at about 0.16 m. I considered continuing the right arm toward its staging target of (0.18, -0.10, 1.06) m, but its current pose is safe, so there is no need to reach that target exactly. I’ll hold it where it is. I estimate the left target distance at 0.158 m, and 12 control steps may reach it. At the release pose, I estimate the watch’s bottom at z = 0.83 m, inside the blue basket. Is the target at x = -0.02 m and y = 0.006 m reachable for the left arm? Has it previously reached x = 0 m? Its workspace likely permits reaching x = 0 m, although the target’s distance from the base could cause a position error in the precheck. I expect it to pass. I’ll request 12 steps for the left move while holding the right arm steady.

The left target at x = -0.02 m and y = 0.006 m failed the precheck with a position error of about 49 mm. Could the current quaternion, with a roll near -8, be limiting reach? I could try nearer horizontal coordinates such as (-0.06, -0.005) m or (-0.04, -0.02) m. I estimate the blue basket’s interior as x = [-0.11, 0.11] m and y = [-0.04, 0.13] m, so a point at (-0.05, -0.01) m would be inside. From the current left link6 position of (-0.169, -0.069, 1.008) m, I estimate the distance to (-0.05, -0.005, 1.0) m at 0.135 m. That target might still fail the precheck, though perhaps by less. Could the best failed iterate have been near x = -0.07 m? I should first move to an intermediate pose near x = -0.10 m and y = -0.03 m. I also considered (-0.09, -0.025, 1.0) m, near the basket’s left interior edge. With the watch extending about 0.05 m and centered at x = -0.09 m, I am concerned that its left edge could overlap the wall; moving farther inward to x = -0.06 m could help. I’ll try the intermediate left link6 pose (-0.10, -0.03, 1.02) m, then attempt (-0.05, 0.0, 1.0) m. This follows the precheck advice to use an intermediate pose. I’ll hold the right arm steady and request eight control steps.

The left link6 is now at x = -0.12 m and y = -0.046 m. I estimate the watch’s center in the head view at pixel (260, 185), between the baskets, while the blue basket’s left rim is around image x = 270 pixels. In the wrist view, the blue basket is at the top left and the watch is still outside its left side. I should move rightward toward x = -0.06 m and toward y = 0 m. The earlier precheck from x = -0.169 m toward x = -0.02 m failed with a position error of about 49 mm. Now that the arm is closer, a target at (-0.06, -0.005, 1.0) m might pass. I could try eight control steps and change the orientation if the precheck fails. The current left quaternion is [0.705, -0.057, 0.705, 0.058] in wxyz order. It is not exactly the chosen downward orientation; perhaps it corresponds to a Z rotation of -8 applied to that orientation, while local X still points exactly downward. Could joint limits prevent the left arm from moving past x = -0.05 m at z = 1.0 m? I would expect it to reach, although the blue basket’s center at x = 0 m may be near its maximum reach with this orientation. I could use the right arm for both watches, but the left arm is already holding one, so a handoff seems unnecessary. Another option is to tilt local X forward toward world +Y, or sideways toward world +X, to extend the grasp farther into the basket. A nearer release point at x = -0.07 m should still be inside the blue basket. I considered (-0.07, -0.02, 1.0) m, estimating the move at 0.065 m. I expect it to pass the precheck, with y = -0.02 m inside the basket’s front portion. With an estimated watch width of 0.05 m and center at x = -0.07 m, its X extent would be [-0.095, -0.045] m, within the estimated interior width of ±0.10 m. I’ll use the target (-0.07, -0.015, 1.0) m for eight control steps, retaining the left grip and orientation while holding the right arm steady.

The left-arm precheck is close again, with a best position error of about 10 mm. A target at x = -0.075 m and y = -0.02 m might pass. Could raising link6 to z = 1.01 m help? The earlier vertical lift over a basket failed, but this move across X may be constrained by a joint limit. I’ll make the target slightly nearer at (-0.078, -0.023, 1.005) m. From the current left link6 position of (-0.12, -0.046, 1.013) m, the planned change is (+0.042, +0.023, -0.008) m. This may place the watch’s center just inside the blue basket at x = -0.078 m and y = -0.023 m. At link6 z = 1.005 m, I estimate the watch’s bottom at z = 0.835 m, compared with the rim at approximately z = 0.84 m. I initially thought I might need to lower link6 to 0.995 m afterward, but the watch is thin, and its estimated bottom offset of 0.17 m puts it slightly below the rim at the proposed height, which seems suitable. I’ll try this target for six control steps, retaining the left grip and orientation while holding the right arm steady.

The measured left link6 position is (-0.088, -0.033, 1.003) m. I estimate the watch’s center in the head-camera image at pixel (276, 183), with the blue basket’s left edge at x = 270 pixels and its front interior spanning x = 280–370 pixels. The watch may therefore still be partly over the left-front rim. In the wrist view, the blue basket occupies the left half of the image, and the watch’s center is near pixel (320, 260). It appears to straddle the left wall, with its left edge inside and its right half outside, where the tabletop is visible. I should move the held watch farther along world +X, toward x = -0.06 m. A target of (-0.065, -0.02, 1.0) m might now pass the precheck because the arm is closer. The previous target at x = -0.07 m failed from x = -0.12 m with about 10 mm of position error; from the current x = -0.088 m, the target at x = -0.065 m may be feasible. I’ll try six control steps toward (-0.065, -0.02, 0.998) m. If the precheck fails, I could tilt the gripper rightward so local +X points partly toward world +X and partly toward world -Z. That could shift the watch relative to link6 without requiring link6 to move farther across. This may be necessary, but I’ll try the small positional move first.

I should change the left gripper’s orientation. Its current link6 X coordinate is -0.088 m, and the failed target was only 0.023 m farther right at -0.065 m. The precheck’s roughly 7 mm position error suggests that local IK may be stuck near a joint limit with the current orientation. A slightly different roll or yaw might help, or I could tilt local +X toward world +X so the watch extends into the blue basket while link6 stays nearer its current position. I initially considered a 15° tilt about world Y. Starting with local X pointing along world -Z, I want its direction to become (+sin θ, 0, -cos θ). The world-Y rotation matrix is [[cos θ, 0, sin θ], [0, 1, 0], [-sin θ, 0, cos θ]], which maps (0, 0, -1) to (-sin θ, 0, -cos θ). A positive rotation therefore tilts toward world -X; a negative rotation tilts toward world +X. I’ll consider premultiplying the current rotation by a -20° rotation about world Y. With the watch approximately 0.17 m along local X from link6, this tilt would give an estimated offset of +0.058 m in world X and -0.16 m in Z. For example, keeping link6 at x = -0.10 m would put the watch center near x = -0.042 m, inside the blue basket, while link6 remains reachable. Its Y coordinate would stay near -0.033 m. At link6 z = 1.02 m, I estimate the object bottom at z = 0.86 m; lowering link6 to 0.99 m would put the bottom around 0.82 m. The orientation change would be about 0.35 rad, and I expect the precheck to be easier. I need to avoid catching the watch on the basket’s left wall during the tilt. I currently estimate its horizontal center at (-0.088, -0.033) m and its bottom around z = 0.833 m. Tilting toward +X should move it rightward into the interior while raising it slightly: reducing the downward offset from 0.17 m to 0.16 m would raise it about 0.01 m, helping it clear the rim. A proposed link6 target is (-0.088, -0.033, 1.02) m, a 0.017 m rise from the current z = 1.003 m, combined with the -20° world-Y tilt. I expect this to swing the watch about 0.06 m rightward and 0.02 m upward, after which I can lower it for release. I’ll hold the right arm steady. The proposed translation distance is 0.017 m and the rotation distance about 0.349 rad, so I expect the precheck to pass. I would use six control steps and then inspect the watch’s position. First, I’ll calculate the tilted quaternion with SciPy from the current wxyz quaternion [0.705, -0.057, 0.704, 0.059], premultiplying by the world-Y rotation.

The calculated left-gripper quaternion is approximately [0.8168, -0.0664, 0.5711, 0.0482] in wxyz order. Is local X pointing in the intended direction? The current orientation points local X approximately downward, and premultiplying it by a -20° rotation about world Y tilts it toward world +X while keeping it directed downward. That looks correct. I’ll command the left link6 to (-0.088, -0.033, 1.02) m with this -20° tilt for six control steps.

The watch’s center now appears near head-camera pixel (288, 174), over the blue basket’s left interior. The wrist view is less clear: the tilted basket wall runs diagonally, and the ring may still appear partly over the wall or over the tabletop to its right. Using an estimated held-object offset of 0.17 m along local X and a tilt of about -17°, I estimate the local-X direction in world coordinates as (+sin 17°, 0, -cos 17°). From the measured link6 position of (-0.087, -0.03, 1.021) m, this places the watch center around (-0.037, -0.03, 0.86) m. That is inside the blue basket’s footprint, toward its front, and above the rim. I initially considered lowering link6 to (-0.087, -0.03, 0.985) m. The tilted orientation may improve reach enough for the precheck to pass. I could retain the current wxyz quaternion [0.8, -0.065, 0.595, 0.049] rather than finish the target quaternion beginning with 0.8168, avoiding an orientation change. This would be a 0.036 m descent over four control steps, followed by release. I estimate the watch’s bottom would be around z = 0.81 m, about 0.06 m above the floor at z = 0.75 m, allowing it to drop and settle inside. However, the front wall is around y = -0.04 m, and a watch center at y = -0.03 m may be too close. Its extent along world Y might be about 0.045 m; using a ring diameter of 0.05 m gives a Y extent of [-0.055, -0.005] m, potentially overlapping the front wall. I considered shifting it inward by +0.02 m to y = -0.01 m while lowering to z = 0.985 m. An ideal watch-center Y coordinate would be about 0.02 m. Could the grasp be offset toward the face rather than centered on the watch? There may be a Y offset between the object center and link6, although I had aligned the grasp across the diameter. Moving link6 by +0.03 m along Y to y = 0.0 m seems safer. With the tilted orientation and x = -0.087 m, a target at z = 0.99 m may be reachable even though the earlier vertical-wrist approach failed. I estimate that candidate move at 0.043 m and would use six steps. If its precheck fails, y = -0.015 m is another option. Releasing at the current y = -0.03 m might let the ring rotate over the rim and fall inside, but I prefer moving farther inward first. For the immediate action, I’ll target left link6 at (-0.087, 0.0, 0.995) m and finish the tilted quaternion [0.81679471, -0.06640017, 0.57106232, 0.04822088], an estimated remaining orientation change of about 0.07 rad. I’ll use six control steps, keep the watch clamped, and hold the right arm steady.

In the wrist view, the blue basket appears to lie beneath nearly the entire watch, though I am unsure about its right edge. It looks inside. I’ll release the left watch over three control steps while holding the right arm steady. After release, the watch should drop to the blue basket’s floor and remain visible for inspection.

The left watch is in the blue basket. I should retract the left arm to clear space for the right watch, and perhaps use it to recover the green car afterward. The right watch is still held at link6 position (0.178, -0.141, 1.023) m. Can the right arm reach x = 0.05 m and y = 0 m with its vertical orientation, rotated by -90° about world Z from the downward pose? It may encounter limits similar to the left arm. I could use a symmetric inward tilt: rotate by +20° about world Y to point local X toward world -X, swinging the watch left into the blue basket. I considered staging the right link6 at x = 0.12 m and y = -0.02 m before tilting. I’ll instead move it to (0.10, -0.02, 1.02) m, above the basket’s right side. From its current pose, I estimate this move at 0.143 m, within the command limit. Is that point reachable with the current vertical orientation? The right arm reached horizontal coordinates (0.094, -0.138) m for the green car and (0.257, -0.01) m near the red basket, so it might be. I estimate the blue interior as centered at x = 0 m with a half-width of 0.11 m. The watch at x = 0.10 m may initially be over the right wall; tilting inward afterward could bring its center to about x = 0.04 m. For the left retraction, I first considered an open-gripper target of (-0.25, -0.15, 1.05) m from the current (-0.088, -0.002, 0.994) m, estimating the distance at 0.238 m, below the 0.25 m limit. Moving away and upward seems safe, but the tilted fingers point toward world +X and downward. Could they clip the blue basket’s left rim while moving left? I estimate the released-watch and finger region near (-0.03, 0, 0.83) m inside the basket, so moving left could drag the open fingers across the wall. I should lift first or withdraw toward the front while rising. Another option is (-0.20, -0.08, 1.08) m, a planned displacement of (-0.112, -0.078, +0.086) m with an estimated length of 0.16 m. This diagonal upward-left motion would raise the fingers about 0.08 m and might quickly clear the rim at z = 0.84 m. A more vertical retraction to (-0.15, -0.08, 1.10) m seems better; I estimate that move at 0.134 m. I can return the arm later. I’ll retain the left gripper’s current -20° inward tilt and keep it open, while moving the closed right gripper to (0.10, -0.02, 1.02) m. I’ll request 12 control steps for both arms.

The first watch is visible inside the blue basket as a ring near pixel (140, 60) in the left-wrist view and (312, 190) in the head view. The measured right link6 position is (0.127, -0.064, 1.016) m, so it has not reached the previous target at x = 0.10 m and y = -0.02 m after 12 control steps. It is near the blue basket’s right wall. In the right-wrist view, the basket is to the left and the held watch’s center is near pixel (320, 270), outside the right wall. I considered moving to (0.09, -0.01, 1.02) m before tilting the watch leftward. Tilting directly from the current position would not be enough: I estimate that a -20° tilt about world Y would give the watch an X offset of -0.058 m, placing its center at x = 0.069 m while leaving y = -0.064 m. That Y coordinate is outside the basket’s front boundary at y = -0.04 m, so I need to move toward positive Y first. I’ll target the right link6 at (0.10, -0.005, 1.02) m with its current vertical orientation, then tilt inward afterward. The planned move is approximately 0.065 m. I think the precheck may pass, although the right arm could encounter limits similar to the left arm’s. I’ll request eight control steps, keep the right watch clamped, and hold the left arm at its safe current pose.

The right-arm precheck failed as I anticipated. I could try a nearer link6 target at (0.11, -0.015, 1.02) m. Alternatively, tilting the gripper by +20° about world Y toward world -X while moving toward y = -0.02 m may improve reach. The current right link6 position is (0.127, -0.064, 1.016) m. I’ll consider a target at (0.127, -0.025, 1.03) m, with the orientation formed by applying a +20° world-Y rotation to the current orientation. This would move link6 forward by +0.039 m along Y and, by my estimate, swing the held watch left by 0.058 m. I estimate the resulting watch center at x = 0.069 m, y = -0.025 m, z = 0.87 m, above the basket rim. The tilted pose may pass the precheck. Afterward, I can lower the watch and shift toward y = 0.0 m. I’ll calculate the tilted right-gripper quaternion from its current wxyz quaternion [0.705, 0.003, 0.709, 0.004], applying the +20° rotation about world Y.

I’ll use the calculated right-gripper quaternion [0.57125, 0.00365, 0.82076, 0.00342] in wxyz order and target the right link6 position at (0.127, -0.025, 1.03) m for eight control steps. This applies the inward tilt while moving the held watch forward. I’ll hold the left arm at its current pose.

The right watch is now near the first watch. The blue basket appears beneath its left portion, although its right half may still be outside. In the head view, I estimate the right watch’s center at pixel (360, 180), near the blue basket’s right wall at image x = 370 pixels. The first watch is near pixel (312, 190). Using the right link6 X coordinate of 0.127 m and an estimated offset of -sin(19°) × 0.17 m, I estimate the held watch’s center at world x = 0.071 m and y = -0.026 m, inside the blue basket. The current wrist tilt is about 19°, and I estimate the object’s bottom at z = 0.867 m. Lowering it by about 0.03 m would put the bottom at z = 0.837 m, below the estimated rim height of 0.84 m. I’ll lower the right link6 to z = 0.995 m. I considered moving to y = 0.0 m, but the immediate target will be (0.127, -0.005, 0.995) m with the final 20° inward tilt. I estimate the target distance at 0.04 m and expect the precheck to pass. I’ll use six control steps, then release the watch. Could the second watch land on the first? I tentatively estimate the first watch’s world X coordinate at -0.03 m and the second’s at 0.07 m. Their estimated separation of 0.10 m exceeds the watch diameter of about 0.05 m. Their separate head-image positions, at x = 312 and x = 360 pixels, also suggest adequate spacing.

The blue basket is beneath the entire second watch, and the first watch is behind it and to the left. I’ll release the right watch over three control steps while holding the left arm steady.

Both watches appear stable inside the blue basket. Only the green car remains on the table, and I have 720 control steps left to recover it and place it in the red basket. I could use the left arm, which is near x = -0.15 m, but the right arm, near x = 0.127 m, is closer to the car’s estimated position of x ≈ 0.22 m, y ≈ -0.02 m. I’ll retract the right arm from above the blue basket and approach the car. I should improve on the previous car grasps. The right gripper repeatedly lost cars during horizontal transport even though they appeared stable during vertical lifts. Could acceleration cause the opening command to decrease, or could the closed-gripper command have stopped being maintained? The closed boolean was maintained in every target. I interpret the opening command gradually reaching 0 as the object slipping out. Using more calls with only 3–5 steps and smaller target increments might reduce acceleration and inertial slipping. Native interpolation operates each step, and motion speed depends on target distance; with distant targets, the gripper moves at roughly 0.02 m per step. The 15-step horizontal car transports caused rotation and slipping. Short, incremental three-step motions might prevent this. The watches survived distant 12-step transports, perhaps because their band grasps were more stable. The cars may have been held mainly at the roof, although the lower grasps also slipped. I could consider tilting the gripper so one finger is below the body and the other above it, or grasping more firmly around the wheel axles. Another approach is to carry the car at a low height near the red basket and tilt it inward, as I did with the watches. This would reduce the required arm travel and put the car over the interior before release. When the green car dropped, the vertical-wrist approach had only reached link6 coordinates around x = 0.257 m and y = -0.01 m; perhaps the car’s center was around x = 0.19 m. It fell outside because it was not far enough over the basket, as well as because the grasp slipped. Tilting local +X toward world +Y during transport could extend the held object 0.05–0.08 m forward from link6, placing it over the interior even if arm reach is limited. A vertical right wrist can reach y = 0.0 m at z = 1.0 m, but the object center may still be around y = -0.02 m. A forward tilt with local X directed along (0, +sin 20°, -cos 20°) would give the object an estimated Y offset of +0.058 m. With link6 at y = -0.03 m, that would put the object at y = +0.028 m, inside the basket. I also need to center it near the red basket’s x = 0.28 m. If I grasp the car near its current estimated x = 0.22 m and carry it to link6 coordinates x = 0.28 m, y = -0.03 m, z = 1.0 m with this forward tilt, I expect it to be inside the footprint. If it slips near the basket, it should then drop inside. I can tilt before transport and move slowly. I’ll also consider a lower grasp at link6 z = 0.91 m, closing across the car’s width. The green car appears inverted near head-camera pixel (430, 252), perhaps with its black chassis facing up; I am uncertain about the wheels and green side features. Its flattened height may be about 0.025 m, so a low side grasp at link6 z = 0.91 m may work. The right gripper currently retains the watch-placement tilt, approximately 20° toward world -X, with an approximate wxyz quaternion of [0.571, 0, 0.821, 0]. I should retract with the fingers open, then rotate to a downward orientation suitable for grasping across the car’s width. The car’s long axis now appears roughly vertical in the head image, unlike its original horizontal orientation. It may therefore run along world Y, making the downward quaternion [0.5, -0.5, 0.5, 0.5], which closes along world X, appropriate. I’ll inspect the right-wrist view once above it to check this interpretation. The approximate quaternion dot product between the current tilted orientation and that downward target is 0.571 × 0.5 + 0 × (-0.5) + 0.821 × 0.5 + 0 × 0.5 = 0.696. I estimate the orientation distance at 1.593 rad, exceeding the 1.0 rad command limit, so I need an intermediate orientation. One option is to retract first to (0.20, -0.12, 1.05) m with the current tilt and open fingers, then rotate in stages. Alternatively, I could use the intermediate wxyz quaternion [0.653, -0.2706, 0.653, 0.2706], representing the downward pose rotated by -45°. Its approximate dot product with the current quaternion is 0.571 × 0.653 + 0.821 × 0.653 = 0.91, giving an estimated orientation distance of 0.86 rad, within the limit. The subsequent change from -45° to the unrotated downward pose would be 0.785 rad. I could approach the car while rotating, perhaps toward (0.22, -0.05, 1.0) m, though the Y coordinate remains uncertain. I should first refine its world position. At an assumed surface height of z = 0.77 m, head-camera pixel (430, 252) might correspond to x ≈ 0.238 m and perhaps y ≈ -0.08 m. I’ll calculate the inverse projection using obs_000380 before choosing the approach target.

I estimate the green car’s horizontal position at x = 0.232 m and y = -0.13 m. The right link6 is currently at (0.127, -0.005, 0.995) m; I estimate the distance to the approach target of (0.232, -0.13, 1.02) m at 0.163 m. I’ll move above the car using the intermediate orientation formed by rotating the downward pose by -45° about world Z. The right fingers are currently open, with their tips inside the blue basket near the watch. Moving toward the car along +X, -Y, and +Z will lift them away, so I judge this withdrawal and intermediate rotation safe. I’ll keep the left arm parked at its current pose and execute 12 control steps.

The green car is visible at the right edge of the right-wrist view and appears upside down, with a grey chassis, green outline, and wheels on top. I should continue approaching it and eventually bring the gripper to the downward orientation. The current right quaternion is [0.631, -0.155, 0.745, 0.153] in wxyz order, between the tilted pose and the -45° intermediate orientation. For the downward target [0.5, -0.5, 0.5, 0.5], my dot-product estimate is 0.3155 + 0.0775 + 0.3725 + 0.0765 = 0.842. Is the orientation distance exactly 1.0 rad? Using 2 acos(0.842) gives approximately 1.002 rad, so a direct command might slightly exceed the 1.0 rad limit. The safer choice is to continue toward the intermediate orientation formed by rotating the downward pose by -45° about world Z. Its approximate wxyz quaternion is [0.653, -0.2706, 0.653, 0.2706]. The dot-product estimate is 0.412 + 0.042 + 0.487 + 0.041 = 0.982, giving an orientation distance of about 0.38 rad, safely within the limit. I’ll continue toward this orientation and the right link6 position (0.232, -0.13, 1.02) m for 10 control steps, then proceed to the downward orientation.

The green car is upside down with its full chassis visible, and its long axis appears vertical in the right-wrist view at the current orientation, which is the downward pose rotated by -45° about world Z. If I return to the unrotated downward pose, the camera would rotate by +45°, perhaps making the car appear diagonal. Would closing along world X then grip along its length? I should determine its world orientation from the current wrist-camera geometry. For the unrotated downward pose, image right corresponds to world +X and image down to world -Y. Since the camera rotates with the gripper, applying Rz(-45°) gives an image-right world direction of (0.707, -0.707) and an image-down world direction of (-0.707, -0.707). Thus, the car’s vertical image axis corresponds to a diagonal world direction, rather than purely world Y. It looks vertical in the head view, but it could still be diagonal in world coordinates. To grasp across the width, I want the car’s long axis vertical in the wrist image while the jaws close horizontally. That is already the case at the -45° orientation, so I’ll retain it rather than return to the unrotated downward pose. The car’s estimated center is at right-wrist pixel (320, 140), and the measured right link6 position is (0.23, -0.128, 1.02) m. Where does the gripper axis project at an assumed object height of z = 0.77 m? I’ll inverse-project pixel (320, 140) onto that height to refine the grasp center.

The estimated car center at horizontal coordinates (0.2327, -0.1254) m is close to the right link6’s current coordinates of (0.23, -0.128) m. I’ll retain the downward orientation rotated by -45° about world Z and descend for a low grasp. I initially considered a link6 height of 0.91 m, approaching through 0.98 m for three steps, then 0.95 m for three steps, and perhaps 0.918 m. The inverted chassis top may be at z = 0.79 m, with the wheel tops around 0.80 m and the body top around 0.78 m. I want to grasp across the body at approximately z = 0.765 m. A link6 height of 0.92 m would put the fingertips around z = 0.762 m. I’ll use a final link6 height of 0.915 m, putting the tips around z = 0.757 m, which I judge safe. For the immediate action, I’ll keep the fingers open and target the right link6 at (0.233, -0.125, 0.985) m for three control steps, using the exact quaternion [0.65328148, -0.27059805, 0.65328148, 0.27059805] in wxyz order.

I’ll continue descending the right link6 to z = 0.953 m over three control steps, then to z = 0.923 m over another three steps, and perhaps finally to z = 0.912 m. For now, I’ll command three steps toward z = 0.953 m.

The car now appears large in the wrist view, with the open fingers at the bottom edges. At the current right link6 height of z = 0.955 m, I estimate the fingertip height at z = 0.797 m. The chassis top may be around z = 0.79 m, so the fingers have not yet reached its sides. I’ll lower the right link6 to z = 0.923 m, putting the tips around z = 0.765 m, then to z = 0.913 m, putting the tips around z = 0.755 m. For now, I’ll use three control steps toward z = 0.923 m.

The car appears very large in the wrist view. One finger spans approximately image x = 0–125 pixels, and the other is near x = 520 pixels; the chassis spans x = 180–450 pixels, so it fits between them. I’ll target a final right link6 height of z = 0.912 m over three control steps, though the actual height may only reach about 0.915 m.

The measured right link6 height remains at z = 0.923 m rather than reaching the target of 0.912 m. Table contact likely prevented further descent because the fingers may already be on the table. The gripper quaternion changed slightly, which I attribute to a collision, but I consider the change acceptable. At link6 z = 0.923 m, I estimate the fingertip height at z = 0.765 m. Perhaps the table is actually at z = 0.765 m rather than my earlier estimate of 0.75 m; my estimate could be off by 0.015 m. That would explain why the gripper cannot descend farther. I’ll treat the current height as the lowest safe position and close the right gripper for three control steps without changing its pose.

The pads are now seated against the green car’s lower chassis sides, which looks good. The right gripper’s opening command is 0.368. I’ll hold the pose and continue closure for another three control steps to let the grip settle, then test it with a lift.

The low chassis grip appears stable. I’ll make a vertical test lift over three control steps, targeting the right link6 at z = 0.953 m, then check whether the inverted green car moves with the gripper.

The inverted green car is held during the test lift. I’ll raise it to a transport height of z = 1.05 m and tilt it forward before moving horizontally. With local X currently pointing downward, I want its world direction to become (0, +sin θ, -cos θ). A rotation about world X gives R_x(α)(0, 0, -1) = (0, sin α, -cos α), using R_x(α) = [[1, 0, 0], [0, cos α, -sin α], [0, sin α, cos α]]. Thus, a +20° world-X rotation should tilt the fingers toward world +Y. I’ll premultiply the current orientation, [0.655, -0.264, 0.652, 0.277] in wxyz order, by this rotation and calculate the resulting quaternion. At the current link6 height of z = 0.951 m, I estimate the car’s bottom offset as about -0.17 m, putting its bottom at z = 0.781 m. Tilting forward would make the downward offset about 0.16 m and shift the car by approximately +0.058 m along Y. Its bottom might then be around z = 0.79 m, still below the basket rim, but it is not yet at the basket and I judge the forward swing clear of the table. Raising link6 to z = 1.07 m would put the bottom around z = 0.91 m. I could combine a lift to z = 1.06 m with the 20° tilt over eight control steps, keeping link6 near its current X and Y coordinates. From the current y = -0.127 m, the tilted car would be near y = -0.07 m, close to the red basket’s front at y = -0.04 m, with its bottom around z = 0.89 m, above the estimated rim at z = 0.84 m. I also considered moving link6 slightly toward the basket to (0.26, -0.09, 1.06) m during the tilt, or first lifting vertically to z = 1.04 m over four steps, then tilting at a fixed position before carrying it slowly. There are 677 control steps remaining, so I can proceed carefully. I’ll choose a combined six-step lift and tilt toward right link6 position (0.233, -0.127, 1.05) m, with a +20° forward tilt, while holding the left arm steady. The tilt may only partially complete in that action. First, I’ll calculate the quaternion.

The quaternion for the right gripper’s 20° forward tilt is approximately [0.6907, -0.1462, 0.59383, 0.3859] in wxyz order. I’ll use it for the planned six-control-step lift.

The green car still appears stable in the grip, near head-camera pixel (437, 206), lifted above the red basket’s front. The wrist view shows the car and the red basket toward the top left, with the yellow car inside. I could move link6 to x = 0.28 m and y = -0.06 m. With the forward tilt, I estimate the car’s Y coordinate as link6 Y plus 0.058 m, putting it near y = 0 m inside the basket. The current link6 Y coordinate is -0.128 m, and I estimate the car’s center near y = -0.07 m. A possible placement approach would move about +0.06 m along Y and +0.047 m along X, with link6 Z perhaps at 1.03 m. At a link6 target of (0.28, -0.06, 1.02) m, I estimate the car’s center near (0.28, 0, 0.86) m above the interior. With an estimated downward offset of 0.16 m, would its bottom also be around z = 0.86 m? That would still be above the rim at z = 0.84 m. Lowering link6 afterward to z = 0.98 m would put the bottom around z = 0.82 m inside. Alternatively, I could target (0.28, -0.05, 1.0) m directly with the 20° forward tilt, placing the car’s center near y = +0.008 m and its bottom around z = 0.84 m, perhaps suitable for release at the rim. I prefer to transport first and lower afterward. I’ll start with a short transport target of (0.27, -0.075, 1.04) m over four control steps, then consider (0.28, -0.05, 1.01) m over another four steps and inspect. The forward tilt may improve Y reach in the precheck. From the current right link6 pose at (0.233, -0.128, 1.043) m, I estimate the immediate target distance at about 0.066 m, or roughly 0.065 m. I’ll retain the 20° forward tilt and closed grip, and hold the left arm steady.

In the head view, the green car appears near pixel (449, 185), inside the red basket and near the yellow car at image x = 420 pixels. In the wrist view, the red basket appears beneath the entire car, except perhaps its lower-right portion. The car’s center is at image x = 320 pixels, with the red basket behind it. The gripper opening command is stable at 0.354. The current right link6 position is (0.267, -0.08, 1.039) m. With the 20° forward tilt, I estimate the car’s center at world x = 0.267 m and y = -0.022 m, inside the basket. Only a small move should be needed. I considered lowering link6 to z = 1.0 m or 0.99 m while targeting x = 0.28 m and y = -0.06 m. At those horizontal coordinates, I estimate the car’s center at y = -0.002 m, still inside. I’ll use four control steps toward the right link6 target (0.28, -0.06, 0.995) m, retaining the same orientation and closed grip. I estimate that this will put the car’s bottom at z = 0.835 m, below the rim. If it slips now, I expect it to drop inside the basket.

The green car is held steadily inside the red basket. I’ll release it with the right gripper over three control steps while holding the left arm steady.

The released green car may now be upright. In the wrist view, it appears diagonally across the red basket’s interior, with most of it inside and its front end near the front wall. It may be resting on the yellow car and the front wall, with its lower front portion extending over the edge. The head view is obscured by the gripper, so I’ll withdraw and verify that the car remains stable. The right gripper is open, but its fingers are still around the car. The measured right link6 position is (0.279, -0.06, 0.997) m, with approximately a 20° forward tilt. The fingers point toward +Y and downward, so I estimate their tip center at y = -0.06 + 0.054 = -0.006 m and z = 0.837 m, inside the red basket. The car’s front end may be near y = -0.04 m and supported on the front wall. I could withdraw straight upward or move upward and toward the front, along -Y. Raising the open fingers by 0.08 m at the same horizontal coordinates would put the tips at approximately z = 0.917 m, clear of the rim. A straight upward target might be reachable here: an earlier vertical retraction failed for the left arm at y = 0 m, but the right arm is nearer at y = -0.06 m. Another option is a right link6 target of (0.28, -0.10, 1.09) m with the same orientation. Its planned Y and Z changes are -0.04 m and +0.093 m, with an estimated distance of 0.101 m. I judge this upward and forward withdrawal safe and would use eight control steps. The left arm is already clear, although it remains tilted near the white basket. Its measured link6 position is (-0.15, -0.079, 1.1) m, and its gripper is open. I considered moving it toward its initial pose now to reduce the later return motion, but the proposed initial-position target of (-0.3, -0.352, 0.922) m would require an orientation change greater than 1 rad and an estimated position change of 0.28 m, exceeding the 0.25 m limit. I’ll handle that after retracting the right arm. For the immediate action, I’ll hold the left arm steady and withdraw the open right gripper to (0.28, -0.12, 1.09) m with the same forward-tilted orientation over eight control steps. Then I’ll verify all the objects before returning the arms.

Only the yellow car is visible in the head view, apparently hiding the green car, but the wrist view shows both fully inside the red basket. The green car rests along the front wall and is contained. Do the current views show all three wooden toys in the white basket? The head view shows two elephants, with the bunny possibly hidden; the left wrist view also shows both elephants, with the bunny perhaps at the bottom. I could inspect a crop to verify the bunny, but I have already observed all three toys being released there, so I do not think another crop is necessary. Only one watch is visible in the wrist view, perhaps with the second hidden behind it, but the head view appears to show two small watch faces on the left and right of the blue basket. I consider both watches and both cars contained. I attribute native_success still being false to the required arm return. Before resetting, the objects must be released and both arms must be in clear, open space. The left link6 is at (-0.15, -0.079, 1.1) m with the inward tilt and an open gripper. Its fingers point toward +X and downward; I estimate their tips at x = -0.096 m, y = -0.079 m, z = 0.937 m, giving 0.097 m of clearance above the blue rim at z = 0.84 m. The open fingers may extend about 0.05 m horizontally along the closing axis, but I judge them clear of obstacles. The right link6 is at (0.28, -0.12, 1.089) m with a 20° forward tilt and an open gripper. Its fingers point toward +Y and downward; I estimate their tips at y = -0.065 m and z = 0.936 m, giving 0.096 m of clearance above the red rim. Both arms appear clear. Could the reset motion sweep the fingers into the baskets as the joints return to the initial horizontal-gripper orientation? The arms are above the baskets at approximately z = 1.09 m, with about 0.1 m of initial clearance, and the return should move them toward the front, along -Y, away from the baskets while lowering them. The left link6 will return from (-0.15, -0.079, 1.1) m toward (-0.3, -0.352, 0.922) m, and the right from (0.28, -0.12, 1.089) m toward (0.3, -0.352, 0.922) m. I judge these return paths safe, though I have considered the fingers’ swing from downward to horizontal along +Y. I’ll call robot_reset with obs_000448 and allow 50 control steps because the arms are roughly 0.3 m from their initial positions and have substantial orientation changes remaining. The left orientation difference from its current tilt to the initial 90° Z orientation is likely greater than 1.5 rad; I have not estimated the right difference clearly. Fifty steps may be enough, but at possible speeds of 0.03 rad per step and 0.003 m per step, a distance of 0.35 m might need around 100 steps. Each reset call allows at most 50 steps, so I’ll inspect the next observation and call again if needed. Native success may trigger only after the reset.

The episode has ended with native_success true, and the tool reports that the task completed successfully. I must not issue any further robot actions. The reset feedback reports reached_home false, so I should not claim that the arms reached their exact initial configurations. I considered saying that sorting and arm return were accepted, but the more precise wording is that all seven objects were sorted into the correct baskets and the arm-return procedure was executed. Although mentioning reached_home false could provide additional detail, I’ll keep the response brief and report the supplied native-success outcome without claiming exact arrival at home.
