I recently saw a video tape of a finger design developed in one of the Japanese industrial labs. Each finger was composed of several hollow channels. By adjusting the air pressure in each of the channels and the relative pressure between the channels you could get the finger to move around in lots of different ways. The video showed several fingers working together handling relatively lightweight objects. When I saw the video and was told how it worked it seemed like a real simple and elegant technique. -- Jim Vallino Siemens Corporate Research, Inc., Princeton, NJ jrv@demon.siemens.com princeton!siemens!demon!jrv (609) 734-3331
