As impressed by we all were by Petman, DARPA and Boston Dynamics' remarkably agile and nimble humanoid, it's about to get upstaged by the company's latest and greatest robot creation: ATLAS. Designed to compete in DARPA's upcoming Robotics Challenge, we actually already got a glimpse of ATLAS' impressive skills back when it was just a prototype, but as it nears completion we're now seeing just how damn impressive it really is.

Not only does it keep its balance and remain standing after being hit by a 20-pound wrecking ball, ATLAS also tackles a treadmill with ease, staying on two feet while two-by-fours and other obstacles are tossed in its path. Is it time to be really impressed, or really scared?
