Named one of Time Magazine's 50 best inventions of 2010, this wearable robotics suit is designed to lighten the load for soldiers lugging weapons and other heavy materiel. Raytheon says the machine uses high-pressure hydraulics to help one person do the work of two or three. It may take years before the suit can be deployed for use with an attached, or tethered, power source, Raytheon says. A suit that operates on its own power will take longer still.
