The robot was developed in South Korea and is currently undergoing its first field trial. Equipped with 3D cameras and software designed to study human behavior, the robot is able to detect abnormal prisoner activity and report back to its controllers.

The robot has been designed to patrol a prison autonomously, but an iPad will allow manual control as well. The next step, say designers, is a robot that conducts body searches although they admit, neither the technology nor the prison system is quite ready for a step that far into the future.
