YAM Geometry
YAM is bimanual. Each follower arm command path uses 6 arm joints plus 1
gripper command. Left/right follower RPCs are separate.
World-frame anchors, checked against the calibrated station XML:
+Z: up.
+X: from the arm bases toward the tabletop workspace; not image-right.
+Y: left-arm side. -Y: right-arm side / scene-right in recent scripts.
- Arm bases: left
[0.2525, +0.31, 0.75], right [0.2525, -0.31, 0.75].
- XML table top is
0.750 m; top-camera support/table estimates often use
~0.760 m. Keep model Z and live-depth support Z separate.
- Trash drop gripper orientation: point along
+X when the gripper should face
away from the robot.
Verify against current overlays and script state before changing waypoints.
