Abstract
The design of a biped humanoid that has multiple motors on each lower body joint is described. The joint actuators of the lower body should have high-power performance with compact size for walking while dynamically supporting the entire weight. The authors propose a design method in which multiple motors are installed in a joint. The method can amplify the joint torque and this is verified by experiments involving measurement of the joint angle and the current with respect to the number of motors on a single joint. The mechanical design and control system are explained. The design results are verified from a walking experiment. The proposed design improved the walking performance.
