The October 14 PingpongDuo paper addresses a doubles-specific problem: two humanoid robots must hit alternately while sharing limited space and avoiding each other.
A team planner selects positioning targets and filters risky movements. Individual controllers separate footwork from racket control, while a residual adjustment refines strikes after movement.
The authors report more than ten consecutive alternating strikes in real experiments, alongside simulation comparisons. These are research demonstrations under the described conditions, rather than proof of general match readiness or a commercially available robot product.
