Watching this video of the Precision Urban Hopper jumping over a fence, makes my inner kid all giddy and excited. It also makes my outer nerd wet. It has been invented by Boston Dynamics, the creators of the scary BigDog.

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]
