Apparently this video contains a demo of an automated robot turret that has a 5.5 mm machine gun built into it. The turret costs around $200,000 and was designed to be deployed at the DMZ in South Korea according to some of the other info listed with the video. It comes with a day and a night camera in addition to people tracking and recognition software (which you'll see in the video). One thing I noticed about the tracking "square" that the software places around people was that it seemed to lag behind the person so I wonder if the gun leads in front of them. It also appears to give the people a chance to surrender before it fires on them. Welcome to the future?
