The novel type actuator for prosthetic arm

Currently, robot actuators are composed of several parts, for examples big bearings, external encoder or potential meter and decelerator like harmonic drive or planetary gears. Most of these parts increase weight and volume of actuator. And these actuators have high speed, low torque. But Prosthetic actuators are demanded high torque and low speed. So, new actuator design will be include several parts in the compact body and has light weight, high torque and low speed.
