The robot was used to dispatch a suspect who opened fire during a Black Lives Matter protest, killing five officers and injuring several more. The unit is supposed to be used for bomb disposal, though it was harnessed by police last week to deliver an explosive instead. While the decision kept officers out of harm's way, some wondered about the implications of police deploying high-tech weapons without oversight. The Andros Mark V-A1, which is made by military tech company Northrop Grumman, contains a surveillance camera and an extendable arm with a rotatable "gripper." It's controlled wirelessly and can climb up stairs.
