RAPHAEL, the robotic hand was developed in the Laboratory of Robotics and Mechanics (Romel), Faculty of Engineering at Virginia Tech is the hand can hold a heavy beat up from a sensitive source of a firm. This robotic hand is articulated by an air compressor to 60 psi by a microcontroller that coordinates the movement of the fingers thereby replacing the use of large motors, as well the use of compressed air allows the robot to hand movements soft, natural, accurate and great sensitivity.
Air Powered Robotic Hand with Elastic Ligaments and Raphael is part of Charlie (Cognitive Learning Humanoid Robot with Intelligence) which is a humanoid bipedal robot, 5 feet tall.
CHARLIE is the first humanoid built in United States with educational goals while ASIMO in Japan shows signs of intelligence and learning to recognize objects visually. The truth is that with this advance in technology is a cheaper option for the production of prostheses that better simulate the natural movements of the hand.
So what would this be used for? You mentioned prosthesis, but could a person really wear a compressed air powered arm? That would require a tank of compressed air on hand at all times.
