A jumping robot (the "Sand Flea")

YouTube link. 

Pretty impressive.

Sand Flea is an 11-lb robot with one trick up its sleeve: Normally it drives like an RC car, but when it needs to it can jump 30 feet into the air. An onboard stabilization system keeps it oriented during flight to improve the view from the video uplink and to control landings. Current development of Sand Flea is funded by the The US Army's Rapid Equipping Force.

Created by Boston Dynamics, who also made the "Big Dog" robot.  Presumably, the "Sand Flea" will later be equipped with reconnaissance equipment and perhaps some lethal weaponry.
