The Sarcos-Raytheon joint effort Exoskeleton has been around for a while, but the companies are trotting it out in honor of the Iron Man movie. This XOS seems really agile and powerful at the same time, but those hooks-for-hands really might be dangerous if you forget you have them on. But as you can see when their own roboman lifts those 200 pounds with barely any effort, it's really really useful. If they can kinda enclose up this suit so the whole thing is bulletproof, flameproof and Iron Monger-proof, we'd be first in line. [Raytheon]
