BigDog robot? Get ready to fall in love all over again. Meet the Sand Flea, a plucky little 11-pound robot that can jump a mind-boggling 30 feet in a single bound, while an on-board stabilization system helps make landings a bit smoother. The RC four-wheeler's development is being funded by the Army's Rapid Equipping Force. Your move, iRobot. Check out some rad video of the big-wheeled 'bot after the break.
