Boston Dynamics demonstrates "LittleDog", a four-legged robot used to bring "supplies for troops.
Each of LittleDog's legs is powered by three electric motors, giving them a lot of flexibility. Sensors measure the angles of each joint as well as body orientation and foot/ground contact. The basic strategy for walking over both smooth and rough terrain is to adjust a smooth walking pattern generator with the selection of every foot placement such that the center of gravity � follows a stable trajectory

It's certainly interesting and shows a lot of promise, but needs more development. I hope the troops are stocked up a year in advance, seeing the rate at which the "dog" moves over some little simulated rocks. What will it carry, some raisins? I think the product would be much more suited to fill in the gap that the SONY dog left when it was withdrawn from the market. Maybe this is just a small scaled proto. Any more information available?

BigDog is the alpha male of the Boston Dynamics family of robots. It is a quadruped robot that walks, runs, and climbs on rough terrain and carries heavy loads. BigDog is powered by a gasoline engine that drives a hydraulic actuation system. BigDog's legs are articulated like an animal's, and have compliant elements that absorb shock and recycle energy from one step to the next. BigDog is the size of a large dog or small mule, measuring 1 meter long, 0.7 meters tall and 75 kg weight.
