You surely have seen robots in various roles in movies as well as in real life. But, I'm sure that you have never seen robots guarding the civialians from criminals. The closet thing you might remember is of the movie RoboCop, where a cyborg roam around the city relentlessly to confront the notorious warlords of Detroit, Michigan. The only problem was, RoboCop was not a robot, although he was guarding the city from the criminals. Seems that South Korean authorities have tweaked the idea a little bit, and deployed a robot designed to guard the world from criminals. Only in this case, the criminals are caged in a high security prison. Yes, a prison in South Korea is testing a robot designed to guard the roughest prison cell blocks.
