In Pictures: US military gets fired up over weapon...
Jason Lohse, of Northrop Grumman, uses a computer and a handheld device, both attached to his vest, to fire an M240 machine gun on the company's CaMEL robot. The vest, which weighs about 10 pounds, also carries a battery and a tablet that flips down from the soldier's chest so he can see what the robot sees. That means the soldier doesn't have to be physically near the target.
