Robotic Hand Driven By ultrasonic Motors

 Five fingered robot hand driven by 20 ultrasonic motors. Each finger has five degrees of freedom. The size is about the same as that of human hands. As ultrasonic motor has characteristics such as rapid response, large torque and silence, it is adequate for robot hand. Speed of fingers is faster than that of humans. So this hand is adequate for use in master-slave system for remote control in the medical and extreme environment. Now researches aiming to construct a master-slave system to show the applicability of our hand to dexterous manipulation.
