Two Humanoids Share a Table Without Crossing Paths
PingpongDuo chooses team positions jointly, filters risky movements and trains footwork and striking skills for rapid handoffs in a confined space.
Summary
PingpongDuo chooses team positions jointly, filters risky movements and trains footwork and striking skills for rapid handoffs in a confined space.
Doubles table tennis forces two humanoids to alternate strikes while repeatedly entering and clearing the same workspace. PingpongDuo gives a team planner learned risk estimates and preserves the current striker's target when alternatives look unsafe. Separate footwork and racket skills are trained on one another's states, with a residual refining strikes after movement. In simulation, the authors report a 13.2 percent gain in return success and roughly two-centimeter clearance positioning error. In hardware tests, one robot completes a 2.15-meter recovery cycle in 2.4 seconds, and two robots sustain more than ten alternating strikes. These are controlled demonstrations, not general human-safe collaboration.
