The BigDog Quadruped Robot

BigDog is a dynamically stable quadruped robot created in 2005 by Boston Dynamics with Foster-Miller, the Jet Propulsion Laboratory, and the Harvard University Concord Field Station

Boston Dynamics keeps working on their BigDog quadruped robot, which will probably grow for the use of the Pentagon. It looks like an actual biological quadruped. But bit freaky to look at.

Seeing it climb through rubble, snow, jumping over obstacles like a wild goat, and saving a near-fall on iced ground at the last second defies belief. This unique robot is even smart enough to balance itself when kicked from the side. It feels so "animal" that we almost feel bad when they hit it to demonstrate how it regains balance on its own.

This new version of the robot can carry 340 pounds, which is almost triple the previous weight.
