Very interesting robot video on this website.

The Most Advanced Quadruped Robot on Earth

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. 

BigDog has an on-board computer that controls locomotion, servos the
legs and handles a wide variety of sensors. BigDog's control system
manages the dynamics of its behavior to keep it balanced, steer,
navigate, and regulate energetics as conditions vary. Sensors for
locomotion include joint position, joint force, ground contact, ground
load, a laser gyroscope, and a stereo vision system. Other sensors focus
on the internal state of BigDog, monitoring the hydraulic pressure, oil
temperature, engine temperature, rpm, battery charge and others.

In separate trials, BigDog runs at 4 mph, climbs slopes up to 35
degrees, walks across rubble, and carries a 340 lb load.

BigDog is being developed by Boston Dynamics with the goal of creating
robots that have rough-terrain mobility that can take them anywhere on
Earth that people and animals can go.  The program is funded by the
Defense Advanced Research Project Agency (DARPA).
