Lightweight High-Speed Multifingered Hand System

Summary

Dynamic grasping using a newly developed high-speed hand system and high-speed vision is proposed. In the high-speed hand system, a newly designed actuator provides the finger with excellent features: It is lightweight (about 110g per finger),and it is moved with speed reaching about 4m/s and 4N power at a finger tip, and backlash is small enough for high-gain feedback control. As a result high-speed motion at 180deg/0.1s is realized. With high-speed visual feedback at a rate of 1KHz, the hand can grasp and handle dynamically moving object. Experimental results are shown in which a falling object is caught by high-speed hand.( Dynamic Catching Page )
