South Korea experiments with robot prison guards.
It's a well known fact of technological progress that machines have been taking a gradually larger share of human work. South Korea is going to push the boundaries of this trend with robot prison guards. This robot, above, will do duty for a month-long trial in the city of Pohang.
As the BBC reports, it's part of a larger, country-wide effort to promote the Korean robotics industry. This particular model looks like it could take a shank or two, but its designers told the BBC it was designed to "look more friendly" to the inmates.
