This guy eats Roombas for breakfast. It's called the Warrior, it weighs 450 pounds, and it can carry stuff, destroy stuff, or do stuff (like opening a door). Although you won't find this bad boy at Sears anytime soon, it is created by the same company everyone knows and loves for the Roomba and Scooba floor-cleaning robots. But iRobot's reach has long extended beyond the domesticated fare. This latest creation is the newest in its history of offering military-grade robotics.
