Poses use metres and extrinsic XYZ radians (`Rz @ Ry @ Rx`) +relative to the flange, independently of the tool/TCP correction. A detachment +uses `shape.detach(world_pose=...)` and removes its contact exemptions. + +Only collision-enabled, nonphysical program shapes can attach. Changes require +idle motion and a fresh position reference. Exact allowed-contact names exempt +only pairs involving their declaring shape: URDF links, `tool:name`, +`shape:name`, or `install:name`, with at most 32 unique partners. Unknown names, +wildcards and self names are refused without changing the applied world. +Unrelated checks stay active during planned and streamed motion. + +Readback includes `attachment_epoch` and `attachments_valid`. Controller/session, +reference, source and selected-tool changes invalidate the old assumptions; +arm motion remains blocked until the declarations are removed or explicitly +reconciled against fresh state. For multiple stale attachments, reapply all +verified declarations together in one `set_shapes` call. Stored world files +do not restore a fresh context. Dry-run clients preserve these context gates. + +These declarations do not actuate a gripper, confirm a grasp or estimate payload. +Waldo Commander supplies `attach_object` / `detach_object` Python skills and +shape-menu controls that use this API and verify controller readback. diff --git a/parol6/PAROL6_ROBOT.py b/parol6/PAROL6_ROBOT.py index d7f1185..cb7ff32 100644 --- a/parol6/PAROL6_ROBOT.py +++ b/parol6/PAROL6_ROBOT.py @@ -313,12 +313,35 @@ def apply_shapes(shapes: "Iterable[Any]") -> None: """ global _active_shape_names, _program_shapes shapes = _validate_shapes(shapes) -

Attaching a part is refused by one gate in the state that also sees a plan still in the planner: the controller records the highest submitted command index and the player the highest one a returned segment accounts for. A hardware E-stop keeps its own error while pressed; the stale-attachment error latches on release. wait_command is paced by the status stream, re-asking the completion query when a frame reports the command done or an error standing, or after 250 ms without one. Query replies are matched by request id alone; the broadcaster reads the session id the state already owns; the dry run's ack folds to one expression; the wire's Attachment import is at module level; the fake serial's E-stop input is driven through press_estop. The in-process controller fixture is shared from conftest, and the blend test keeps only the pause half of a case the record test already covers.
