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).

It can over come a stumble, but can it get up after it's been knocked down?

I'd imagine this would be invaluable to the troops, although it doesn't look very stable on snow.

HAHHAHAHAH thats the fucking weirdest ting ever
For those considering buying a new vehicle, don't forget to check out the new 2008 Toyota FJ Cruiser. Great for adventures off road, just for cruising around town, or running to the store.

The new 2008 Toyota FJ Cruiser seats five and comes in two-tone with a Voodoo Blue, Titanium Metallic, Black Diamond, Sun Fusion, Sandstorm or Brick body color and White top. The interior fabric color is Dark Charcoal, while the dash, center instrument panel trim and the door inserts match the body.
