Researchers have developed a novel data-driven method for controlling physics-based, muscle-driven hands to play piano with remarkable dexterity. Their hierarchical approach combines high-frequency muscle control with low-frequency latent-space coordination, enabling the hands to perform new musical pieces. The system utilizes reinforcement learning for muscle activation tracking and a variational autoencoder to abstract muscle dynamics, allowing for piece-specific coordination policies. This method achieves state-of-the-art performance in physics-based dexterous control for piano playing and generates physiologically plausible muscle activation patterns. AI
