MULE Robots Ready For The Battlefield

At a desert test site in Texas, a street battle rages between US soldiers and local "insurgents". It's much like any other training exercise, except the soldiers are accompanied by a Mule (Multifunctional utility/Logistics & Equipment), an armed robot the size of a Humvee. The insurgents are positioned overlooking an intersection, a potential kill zone. The commander pulls out what looks like a PlayStation gamepad and the Mule is sent forward. It presents a tougher challenge than the typical human soldier. The Mule can fire Javelin anti-tank missiles and has a turret-mounted machine gun, in addition to a digital "eyeball" with laser and heat-recognising target acquisition systems for aiming its weaponry. It is semi-autonomous, using GPS to navigate and localised perception to avoid trees and buildings. Its six wheels are on pneumatic legs, enabling it to climb over cars and barriers. Within minutes, the formerly deadly intersection is secure.
