Vigilante robot

Rufus Terrill has had it with the drug dealers, petty thieves and vandals he says roam the streets outside his downtown Atlanta bar, O'Terrills. Instead of calling the police or hiring private security guards, Terrill built his own security robot.

The robot is controlled remotely, has a spotlight and a water gun, and Terrill uses a walkie-talkie to boom his disembodied voice over the robot's sound system.

"I tell them they are trespassing, it's private property, and they have to leave," Terrill says, "They throw bottles and cans at it. That's when I shoot the water cannon. They just scatter like roaches."
