The XOS is essentially a wearable robot suit that fits around your body like an exoskeleton, enabling soldiers to easily lift 200-pound weights and missiles. For those who missed the video, check it after the break. Click here for first picture in gallery.

Basically the suit has an array of sensors that track the pilot’s movements, echoing them with its hydraulic muscles at the same speed. This takes some pretty fancy math so that the machine can react quickly enough to avoid introducing a very limiting motion-lag.
