BigDog: Large Quadruped Robot

Posted on May 31, 2007

The video shows what BigDog, an advanced quadruped robot, can do. BigDog can walk over rocks and stay upright even after being kicked. Roborama explained how BigDog is powered.
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.
