Some robots have been tapped for military service. The army has begun testing Boston Dynamic's RHex--a six-legged, 30-pound crawling robot inspired by the cockroach--in Afghanistan. With its sealed body, RHex can climb in rock fields, mud, sand, and vegetation, across railroad tracks, up telephone poles, slopes, and stairways. RHex is controlled remotely at distances up to 700 meters, and IR cameras and illuminators provide front and rear views from the robot.
