Outline of Final Research Achievements

In everyday life, the central nervous system always selects an appropriate solution among the enormous possibilities for achieving a desired movement. In this study, we focused on body coordination, in particular at the muscle level, to unravel the mechanism to control the neuro-musculoskeletal system with multiple redundant muscles. New technology on muscle synergy analysis revealed two functions of muscle synergies and we proposed the model of motor control and learning based on muscle synergies. The validity of the proposed method was confirmed by some experiments including the control of a human-like musculoskeletal robot system.
