Overview
- The March 16 video shows a Unitree G1 returning shots against a human opponent using what appears to be a standard tennis racket.
- In simulation, the LATENT system reached up to 96% success on forehands, and in the real-world test the robot sustained rallies and reacted to balls over 15 m/s.
- Training relied on short motion fragments such as forehands, backhands, and side steps captured in a compact 3×5 meter space from five participants totaling about five hours.
- To narrow the sim-to-real gap, the team randomized key physical parameters including mass, friction, and aerodynamics during simulation training.
- Galbot worked with researchers from Tsinghua and Peking Universities, has released a not-yet–peer-reviewed paper, and says the approach could extend beyond tennis though validation remains limited to controlled demos.
