BigDog robot to carry gear for troops

It can carry loads of up to 120 pounds, amble along at 3.3 miles per hour, climb hills, and can follow a path by itself via stereo vision or be controlled via remote. It's BigDog, the gasoline-powered, gyro-stabilized, 2.3-foot tall, 165-pound pack mule of the future. BigDog is being developed by defense contractors Boston Dynamics, and will, we assume, be the best pal for the robot army of the future. And just for the record, we're pretty confident that BigDog could take down any spare Aibos that Sony has left lying around.
