The machine in the foreground is a multifunctional advance remote control (MARC) bot. Here, it's being used by a soldier of Company A, 91st Engineer Battalion, 1st Cavalry Division, as part of a search patrol through the streets of Baghdad for improvised explosive devices. The $3,000 robot has all-terrain wheels and a retractable arm with a camera.
