This mechanical robo suit is lighter, faster and stronger than the original XOS 1, yet uses half the power. It currently is tethered, or stand alone prototype. It is designed to make several arduous and physically demanding tasks easier, particularly pertaining to military use. "The XOS 2 robotics suit is being designed to help with the many logistics challenges faced by the military both on and off the battlefield. The US Defense Advanced Research Projects Agency (DARPA) has long harboured a desire to extend the human capabilities of soldiers through wearable robot exoskeletons to create superhuman strength, speed and stamina."

The XOS 2 enables its wearer to easily lift 200 pounds several hundred times without tiring.
Yet it is still graceful enough to kick a soccer ball, punch a speed bag, or climb stares. It is like a bionic suit only different.
