The other day a company released footage of a robot exoskeleton that was designed to give soldiers increased strength and stamina on the battlefield. The problem is that no matter how strong we make our soldiers, they will always be susceptible to fatigue, bodily harm, and things like chemical attacks. That's why defense contractors and private companies are working on remote controlled and autonomous robots to help a variety of people—from soldiers in war to local police forces to the elderly—sometimes with disastrously creepy results (including a serious plunge into the uncanny valley). Here's a sampling of some of the stranger robots out there, and what their potential uses may be.
