iRobot, makers of those cute vacuums, also produces badass, Rambo-esque killing machines. Their newest creation, the iRobot Warrior, is a 250lb beast that can move 12mph over varied terrain, including stairs, while carrying up to 100lbs on its back. Admittedly the device is not planned for killing (yet), but will instead be used for explosive disposal, casualty extraction and firefighting.
Then you find yourself doing the math...100lb payload...casualty extraction...180lb male...not all in one piece. War sucks, even with robotic companions.
Thanks for making me sad, David!
