Problem
Cartesian and keyboard EEF-twist control used a custom Pinocchio IK implementation. Not quite extensible.
Solution
Pink is now the sole Cartesian and EEF-twist control IK backend. Both task types share the Cartesian pipeline, re-anchor every solve to measured joint state, bound control dt once per task tick, enforce model and joint mappings, and hold measured position for expected solve failures.
All shipped manipulator teleop blueprints, including Piper, now use direct URDF/Xacro models with named end-effector frames. Pink remains optional: task modules import without it, while constructing a Pink task without the manipulation extra gives an actionable install instruction.
The legacy Pinocchio control IK fallback and all self-collision logic were removed from this control path.
How to Test
Run Piper keyboard teleop with the manipulation extra and robot connection configured:
