Paul Chappell and other researchers at the University of Southampton have developed a robot hand that mimics the movements and capabilities of the human hand closer than anything to date according to a EurekAlert press release. The hand contains six independent motors and includes what the developers claim is the first true artificially-made opposable thumb. The hand is indended for use as a prosthetic device. An internal processing unit converts small movements of the human wrist muscles into control signals for the hand allowing complex manipulation. The hand also has built in pressure sensors that detect if an object is being gripped tightly enough to prevent slipage. Best of all, the hand weighs in at just under what a real human hand weighs, making it more comfortable to wear than other heavy prosthetics.
