Last week several companies demonstrated robots for the U.S. Army at Fort Benning, GA. The highlight was four robots firing machine guns with live ammunition.

Of course these robots are not autonomous and require a human controller to operate. Depending on your point of view, these robots are either pretty cool or pretty scary. As an old infantryman, I lean more to the cool side since I see the usefulness of a robotic all terrain vehicle that can carry over 1000 lbs of gear and fire a machine gun.
