Starting from March 2012, a jail in Pohang, along the east coast of South Korea will have a new form of personnel-robot guards. The robot guards will act as helpers and will have the role of moving up and down the corridors recording everything as well as detecting risky behavior.
This new security measure comes at a whopping investment of 1 billion won, approximately $886,000, and will soon be used to replace human guards.
The robots guards will only serve as a monitoring device and do not have the capacity to kill difficult or risky prisoners. They are mostly helpers who can attend to prisoners who are sick or in life threatening situations.
While doing their daily round ups if the robot guards notice anything unusual, they can send an alert to human guards who will then do the necessary.
