JSC2004-E-03468 (March 2004) --- This closeup view, photographed during a series of evaluations, shows the hand of a Robonaut grasping a tether hook. Joint travel for the wrist pitch and yaw is designed to meet or exceed that of the human hand in a pressurized glove and the hand and wrist parts are sized to reproduce the necessary strength to meet maximum crew requirements for extravehicular activity. Future robots like the Robonaut prototype may some day help astronauts perform important spacewalk tasks.
