The idea is that the robots will roll around the prison monitoring conditions inside the cells and communicate back to human guards if they detect a problem such as violence. Apparently the human guards are happy with the idea because they get to do less, especially overnight. And if you were worried about Skynet, you needn't be: according to Prof. Lee Baik-chul of Kyonggi University, who's running the trial, '... the robots are not terminators. Their job is not cracking down on violent prisoners. They are helpers.' Good to know.
