An artificial hand built in the UK has fingertip sensors that let it grasp delicate objects without crushing or dropping them.
A previous prototype has proved itself capable of grappling with door keys and twisting the lid off a jar (see New robot hand is even more human). The latest incarnation not only moves more like a real hand but also has improved sense of touch (990KB, Windows Media Player format).
“We’ve added new arrays of sensors that allow it to sense temperature, grip-force and whether an object is slipping,” says Neil White, an electronic engineer at Southampton University who developed the hand with colleagues Paul Chappell, Andy Cranny and Darryl Cotton.
