Virtual reality in undersea exploration: bench testing of an undersea tele-robotic robot arm, being developed for the U.S. Navy by the Centre for Engineering Design at the University of Utah, Salt Lake City. The functions of this robot are the performance of complex underwater tasks by remote manipulation from the surface. Underwater video cameras & other imaging systems relay information to a computer that produces a 3-D virtual image of the seabed. The operator is linked to this world through a headset equipped with 3-D goggles, & spatial sensor, and data gloves or other clothing that relay precision movements back through the computer to tools on the robot's limbs.
