An anonymous reader writes "According to this IEEE story, iRobot and the US military have released video showing a weaponized version of iRobot's Warrior robot. In the video, the Warrior is seen firing a weapon system called the APOBS (Anti-Personnel Obstacle Breaching System), a grenade-filled line propelled by a rocket and stabilized by a drogue parachute. This system is used to clear minefields and obstructed roads. The video shows soldiers deploying a Warrior with the APOBS mounted on its back. The robot fires the device, which lands along a dirt road, exploding after a few seconds. A voice is then heard, 'Road clear; proceed forward.'"
