Thanks to the efforts of Argo Medical Technologies, paraplegics may soon be given the chance to know what it's like to stand up and walk again. Engineer Amit Goffer, founder of the Israeli high-tech company, developed an electronic exoskeleton called "ReWalk", which can help people paralyzed from the waist down to stand, walk, and even climb stairs.

A robot in an armored vehicle may one day be one of the most valuable pieces of equipment in the military, maybe even more valuable than its other robotic counterparts in the service.

The military is already working on a number of robots that will one day serve alongside grunts in the front lines. Soldiers will swear by this "bucket of bolts," probably even salute it as they pass it by. Yet this one doesn't carry any weaponry. This one's literally a lifesaver.

Doctors Blake Hannaford, Jacob Rosen, Mika Sinanan, and Richard Satava, with funding from a Department of Defense medical research program, are working to perfect the technology for robot surgeons to be deployed to the battlefield.  Doctors working from back home can operate them by remote control and communication networks (like via satellites or the Internet) to treat soldiers who would otherwise die without going under the knife - a concept known as telesurgery.
