Abstract
A system for assisting the motion of a body connected through joints provides a system for imparting a suitable torque to the connected body at the time of various turns including the bending of the joints. The torque imparting system has first and second measuring means, a reference work volume determining means, and an external torque determining means. The first measuring means measures the internal work volume of the around-joint leg. The second measuring means measures an external work volume around a joint imparted to the leg. The reference work volume determining means determines a reference work volume based on the internal work volume. The external torque determining means determines an external torque imparted to the leg so as to reduce the difference between the internal work volume of the leg and the reference work volume, based on the external work volume.
