Cooperative Dual-Arm Flexible Payload Damping

A single robotic arm repositioning a large, structurally flexible payload in microgravity has nothing else holding the payload rigid — the free end lags, bends and rings after every move. Grip the same payload at both ends with two arms and the physics can go either way: uncoordinated forces working against each other pump more energy into the structure's bending than a single arm ever would, while genuinely coordinated arms — each sensing the other's motion and countering it — actively damp the shared vibration out in a fraction of the time. Run the same commanded move under all three modes and compare the vibration-amplitude traces directly.
