Researchers have developed a novel three-stage pipeline to transform motion imitation skills into reusable hybrid motion priors (HMPs) for humanoid robots. This method first trains an expert policy to mimic human motion capture data, then distills this expertise into a frozen architecture comprising a proprioceptive encoder, a residual vector-quantized (RVQ) codebook, and an action decoder. Finally, task-specific policies are trained by selecting discrete codebook entries, allowing the HMP to be reused across various locomotion tasks without retraining. The system has been evaluated in simulation for velocity tracking, goal navigation, and fall recovery, and a velocity-tracking policy was successfully deployed on a real Unitree G1 robot. AI
