Reflex teaches a Unitree G1 humanoid to catch boxes thrown by humans

DJiafei · x · 2026-10-09

The Reflex framework enables a Unitree G1 humanoid to catch human-thrown boxes using only onboard RGB-D sensing, with about one second to perceive, predict and move the whole body. The team argues catching is harder than fighting for humanoids, requiring whole-body control, real-time object dynamics reaction, and egocentric visual grounding. Training details, results and open-source code follow in the thread.
