Prosthetic robot arm put to the test by Darpa

A robot arm capable of picking up delicate objects has been approved for use by US medical authorities.

The Deka Arm has fingers that can move much like real ones making it easier for amputees to feed themselves, zip up clothes and unlock doors.

The Arm was developed with $40m (£24m) of research cash provided by the US Defense Advanced Research Projects Agency (Darpa).
