The dusty corners of the Robotics Institute serve as retirement spots for robots who've paved the way in their technological fields. This is Nomad, an autonomous bot that preceded Zoe in the Atacama Desert and was later used to search for meteorites in Antarctica. In the late '90s, its in-wheel propulsion, transforming chassis, and hi-res stereo vision were cutting edge; now it waits for the company of robots like Scarab and the X-Prize robot in the afterlife.
