What Happens When Your Bomb-Defusing Robot Becomes a Weapon


Micah Xavier Johnson spent the last day of his life in a standoff, holed up in a Dallas community-college building. By that point, he had already shot 16 people. Negotiators were called in, but it was 2:30 in the morning and the police chief was tired. He’d lost two officers. Nine others were injured. Three of them would later die. In the early hours of July 7, 2016, the chief asked his swat team to come up with a plan that wouldn’t put anyone else in Johnson’s line of fire.

Within 30 minutes, their Remotec Andros Mark 5A-1, a four-wheeled robot made by Northrop Grumman, was on the scene. The Mark 5A-1 had originally been purchased for help with bomb disposal. But that morning, the police attached a pound of C4 explosives to the robot’s extended arm, and sent it down the hallway where Johnson had barricaded himself. The bomb killed him instantly. The machine remained functional.
