Amazing BigDog Quadruped Robot by Boston Dynamics

Here are a couple of videos of the amazing and somewhat creepy all terrain BigDog Quadruped Robot created by Boston Dynamics, an engineering company that specializes in robotics and human simulation.

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 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.
