BigDog is the most advanced quadruped robot on earth. It’s being developed for the Pentagon. It’s a four-legged robot capable of carrying 340 pounds.

That’s the official description. I think BigDog looks like a giant mosquito. It has an engine that buzzes. It looks for all the world like an escapee from a horror movie. If you were an enemy soldier, it would give you nightmares.

I cannot write a description that does this thing justice. But I can tell you this. After watching this video, you will not soon forget BigDog.
