Quadruped Robot a Little Too Life Like
This robot developed by Boston Dynamics is simply amazing – apparently, the most advanced quadruped robot on earth. Boston Dynamics, the brains behind the machine, is a an engineering company that specializes in robotics and human simulation with primarily military applications.
Boston Dynamics' site describes the machine:
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.
