grasping-direct-ik
De la autor
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 so the hand's declared closing axis (robot.describe_gripper, composed by robot.grasp_frame) closes across the target's short horizontal axis, and the hover clearance is the hand's own (robot.describe_workspace) unless the workflow pins it. Use when no trajectory planner (curobo) is deployed or the scene is uncluttered enough that a straight-line approach is safe.

- grasping-with-plannergraph-robots/open-robot-skillsTop-down grasping via a fast axis-locked linear descend with a collision-aware cuRobo fallback. A single `grasp_descend_linear` node rises, translates over the target, and descends straight down (Z-locked, orientation held) onto the object; if the straight-line solve is infeasible (far-edge reach, no IK for the fixed wrist) it falls back to the cuRobo planner over the candidate fan. Use when the curobo tool bundle is installed and a perceived object (OBB) must be grasped — the default grasping skill whenever cuRobo is deployed, in clean and cluttered scenes alike.Planificare★ 58
- transporting-objectsgraph-robots/open-robot-skillsMove the currently-held object to a destination and release. The gripper enters this subgraph holding the object; on exit the object has been placed. For a walled container (basket / bin / box / tote) the default is a straight-Z descent to inside the walls (transport_descend_linear → release); for placement ONTO a surface or into a described sub-region it computes an explicit drop pose (compute_drop → move_above → release). Use after a successful grasp when the destination has a known OBB. When the destination is a sub-region described in natural language (e.g. "the left compartment of the caddy", "to the left of the plate", "the inside of the top drawer"), an optional VLM-grounded perceive_zone state localizes the zone before the drop pose is computed. Heights derive from the perceived container and the live wrist pose rather than a resting tool height, and the top-down orientation from the hand actually on the arm (robot.grasp_frame).Altele★ 58
- grasping-short-axisgraph-robots/open-robot-skillsDeterministic short-axis-aligned grasp with CuRobo. The grasp pose is computed geometrically (NOT sampled/scored) — the gripper approaches straight down with its finger-opening axis locked to the OBB's SHORTER horizontal axis, so the jaws close ACROSS the narrow dimension of an elongated target. Use for pan/pot handles, bottles, tools, utensils — anywhere the OBB centroid is graspable but orientation is the thing that matters. An optional offset_from_base node slides the grasp outward along the handle, clear of the heavier object body, when a second OBB of that body is wired in. A scored/sampled pose often holds at close but shears out under the lift; the short-axis pose grips the bar squarely so it survives lift + transport.Documente★ 58
- selecting-reachable-graspgraph-robots/open-robot-skillsWalk a ranked list of candidate grasp poses and take the first the arm can actually reach — IK solves it, the solution lands where it was asked, and (where `sim.clearance` is available) the arm is clear of the scene there. Use after any propose rung. This is the fix for taking candidate 0 on faith and closing the jaws on nothing.Altele★ 58
- grasping-linear-featuregraph-robots/open-robot-skillsFit 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 when an upright OBB and vertical approach are sufficient.Altele★ 58
- proposing-short-axis-graspsgraph-robots/open-robot-skillsPropose top-down grasps whose jaws close ACROSS an elongated object's short axis, derived from its oriented box. Use when the object is longer than it is wide, as the first grasp-proposal rung — a handle, a spanner, a screwdriver, a bar, a laid-down bottle — where closing along the length would put the fingers down the object and meet them on each other. Declines when the short axis is wider than the hand opens, which is the signal to try `proposing-side-grasps` rather than to re-tune this one.Altele★ 58
