Do the locomotion.

The article presents information on a concept vehicle (segway robot) Segfrieda, a two-wheeled scooter that was launched in 2002. When the Segway hit the streets, the Pentagon's research agency, DARPA, was one of its first customers, buying a fleet and handing them out to a select group of robotics labs. Andrew Howard, a roboticist at the University of Southern California in Los Angeles, is using his Segway robot to develop methods for mapping urban terrain--especially collapsed buildings.
