Robots copy walking styles from motion examples
Disney Research and ETH Zurich demonstrated a locomotion system that takes a movement-style example and a joystick velocity command as separate inputs. A style encoder conditions an autoregressive diffusion model, which generates reference motions for a reinforcement-learning controller to follow.
The team demonstrated real-time control and continuous style changes in a simulated humanoid and on a physical robot. The method learns from unstructured motion recordings without explicit style labels and can reproduce styles not seen during training.
