The silver, three-wheeled RAVEN moon rover is the size of a golf cart, weighs 800 pounds, and is powered by two super-size car batteries. Its "brain" is the same kind of computer processor found in a netbook. Students in the Department of Aerospace Engineering's Space Systems Laboratory built the rover, which won a NASA design competition. As a smart, mobile assistant for astronauts, the rover and its robotic arm theoretically could follow instructions to bore holes into the moon's surface, collect rock samples and even carry an astronaut to safety in an emergency. Space systems lab students also designed a companion spacesuit to allow an astronaut to give the rover voice and keypad commands remotely.
