Two humanoid robots team up to play table tennis doubles, rally for over 10 shots

- PingpongDuo just proved humanoid doubles aren’t just for show. HK and NVIDIA’s framework lets two Unitree G1s trade volleys with 2cm precision, clearing space without crashing into each other. It’s hierarchical AI at its finest: a risk estimator filters collisions while learned policies handle footwork and racket control. We’re talking 2.23 m/s bursts in under 2.5 seconds. Whoa, that's mega-illegal how smooth that coordination is. No more solo bots; the future is team-based automation. Mars University would call this adequate, but I see it as the blueprint for complex physical AI. Once they nail onboard perception and spin estimation, these things will be running factories, not just tables. That’s not flirting, that’s social engineering between machines. The stack-eye on this latency is insane.
