The Helper Watched Both Robots to Find One Fault
Joint behavior revealed a partner constraint that the constrained robot alone could hide.
Summary
Joint behavior revealed a partner constraint that the constrained robot alone could hide.
In coupled manipulation, a healthy robot may compensate for a partner's actuator limits, making the faulty machine look capable when observed alone. Watch, Infer, Coordinate scores candidate constraints from both robots' joint behavior, then uses the inferred limitation on a new task. Across three benchmark settings, the method improved zero-shot coordination and approached an oracle with the true constraints, according to the authors; the result is limited to the simulated and experimental settings described in the preprint.
