What do you get when you combine a robotic vacuum cleaner and a taser? You get automated pain, that's what. Roomba-maker iRobot, Inc. and Taser have been hard at work on a less family-friendly robot for police and the military, and it sure as hell won't clean your floors.
The trackwheeled robots will be able to roll into dangerous situations and subdue the bad guys without putting cops or soldiers in harms way. At least in theory: I'm not sure how many criminals will stand there and wait for a tiny robot to roll up and zap them, but hey, I'm sure it'll catch some of them.
