In honor of Memorial Day, we’re taking a look at a selection of military hardware and vehicles, including some of the latest technology deployed on the modern frontlines. The iRobot Warrior is one great example. Designed as a multi-mission, unmanned ground vehicle, or UGV, the Warrior is a flexible utility robot capable of tackling dangerous situations without placing U.S. soldiers in direct danger. It’s produced by the Massachusetts-based iRobot Corporation, which just so happens to be the same company that makes the Roomba, that vacuum disc you see cats riding around on the Internet. But the Warrior isn’t a joke – this machine is a highly versatile battlefield asset capable of saving lives.
