Grasp an awkward rigid part by the waists in its own silhouette — take the alpha shape of its point cloud from above, find where that boundary turns inward, and close the jaws across a pair of those inward runs. Use when a part has no graspable long axis and…
Fit the full 3D axis of an elongated segmented feature and grasp it with a perpendicular, inclination-aware parallel-jaw pose. Use for handles, rods, shafts, tools, utensils, and other linear parts whose pitch or roll matters; use grasping-short-axis instead…
Ordered centrelines of deformable linear objects — skeletonises a cable, rope or hose mask, recovers one traversal order through occlusion breaks and self-crossings (TrackDLO's chain merge), back-projects the ordered pixels through depth onto the object's…
Locates a language-described functional part of a rigid object or fixture from calibrated RGB-D and fits a typed loop, shaft, tip, aperture, surface, or region feature with a metric centre, axis, and radius, either inside an already-segmented parent or end to…
Executes a supplied feature-mating plan for an already-held rigid object - collision-aware planner legs tracked to millimetre precision, Cartesian servo for short corrections and fixture crossings, contact-controlled seating - then releases and retreats along…
Executes an ordered, collision-aware pose sequence for an already-grasped rigid object without releasing it - the escape from support, clear-space rotation, fixture transit and orientation-locked local legs of a carry plan, or only the free-space approach…
Direct IK align-then-descend grasping. The gripper pre-rotates to the grasp orientation at a safe height ABOVE the target before descending straight down, avoiding the twist-while-closing failure mode of a blended rotate+descend. The grasp rotation is rebuilt…
Reconstructs a planner collision world from calibrated RGB-D views alone, excluding the grasp target, the robot, and a perceived fixture mask, dropping depth-edge slivers and invalid-depth sheets, and carving the free space an intentional-contact goal needs…
