Boston Dynamics—the folks behind the brick-tossing BigDog—has released some new footage of one its other incredibly unsettling robotic creations. Petman's designed to serve as a testbed for hazmat suits and other military garb, and is so realistic it's hard to believe there's not a real dude inside that suit.

This is the new Petman, by our friends at Boston Dynamics, the creators of Big Dog and BigDog 2. It's like a robotic marine that never gets tired. You tell him to give you a thousand and he'll do it.
