The Precision Urban Hopper—developed for DARPA—is a GPS-guided robot designed for exploration of urban warfare environments. It has a piston-actuated leg that will launch it over any obstacle up to 25 feet (7.5 meters) high. For the record: The piston-actuated leg should be obligatory in every single RC car, skateboard, and Converse shoe from now on. Who is with me? Write to your congressman now, damnit. [BBC News]
