Electronic Adjustable Prehension Hand

摘要

The design of an electrically powered No. 3 hand is described. A prototype hand was built containing an electronic circuit with a potentiometer for manually varying the prehension force from one to ten pounds. Closing speed was approximately two seconds. The weight of the hand was about 1.24 pounds. This weight was considered excessive and an effort at reducing the weight resulted in only a 15% reduction. The hand will be redesigned with a fourteen ounce weight limitation. (Author)
