Boston Dynamics’ "BigDog"
It seems that Boston Dynamics, "an engineering company that specializes in robotics and human simulation," has created the most advanced quadruped robot on Earth, called "BigDog." Here is the video that can be found on YouTube:
Quite honestly, this thing is amazing. I have never seen a robot move with the precision, and "normalcy" that this one does. It walks exactly like a dog. The freakiest moment of the video, though was when it was slipping on the ice, and trying to recover it’s footing. At that moment, it looked more like a real animal than a noisy robot. I think these guys have their finger on the pulse of the future, and we’ll be seeing quite a few of their creations on the battlefield, as the project was funded in part by DARPA.
