Autonomous robotruck could save troops

The Heavy Expanded Mobility Tactical Truck (HEMTT) A4, which charts its own course without human intervention, weighs 31 tons and can carry a 13-ton payload. It will debut next month at the Association of the U.S. Army annual convention, Oshkosh officials say.

The vehicle will perform such tasks as basic navigation, staying in the lane, and passing a static obstacle. The truck could also drive itself while a soldier rides along.
