Boston Dynamics Big Dog (new video March 2008)

BigDog has been developed by Boston Dynamics - a robotics company - in response to a request by the Defense Advanced Research Projects Agency to carry soldiers' equipment across rough terrain. BigDog has four legs allowing it to traverse areas that wheeled or tracked vehicles cannot move across and carries a laser gyroscope and stereo vision system. If the Skynet-like vision of a four-legged military robot tramping through woodland in the snow is not frightening enough, then the segment when BigDog is pushed off balance and staggers drunkenly sideways is surely one of the creepiest things ever to appear on YouTube.
