This paper reports development of a real-time remote control system for robots using augmented reality (AR) technology. An operator can control a robot via the Internet or LAN in real-time by using the system, obtaining an image composed of a remote web camera image and 3D virtual objects. In the paper, a transmission method of the web camera image using UDP and an application method of AR are explained and application of the system to the treasure hunter robot exhibited in Akagane Industrial Expo 2012 is presented.
