NASA’s iRobot PackBot looks inside Japan’s nuclear reactor

Design techniques honed at NASA’s Jet Propulsion Laboratory in Pasadena, Calif., for Mars rovers were used to create the rover currently examining the inside of Japan’s nuclear reactors, in areas not yet deemed safe for human crews.

The iRobot PackBot employs technologies used previously in the design of "Rocky-7," which served as a terrestrial test bed at JPL for the current twin Mars rovers, Spirit and Opportunity. PackBot’s structural features are modeled after Rocky-7, including the lightweight, high-torque actuators that control the rover; and its strong, lightweight frame structure and sheet-metal chassis.

PackBot’s other "ancestor," called Urbie, was an urban reconnaissance robot with military and disaster response applications.
