Robot Guards will soon begin Patrolling South Korean Prisons

Robot guards with sensors to detect abnormal behaviour will soon begin patrolling South Korean prisons to ease the burden on their human counterparts. A group of scientists has developed the robot warders which can connect prisoners with officers through a remote conversation function. The robots – 1.5 metres (five feet) high and running on four wheels – will mostly be used at night. The robots’ sensors will enable them to detect abnormalities such as suicidal behaviour and violence and report it to officers in charge. (EPA/YONHAP)
