This paper discusses human-friendly interface of a teleoperated mobile robot. We consider that a human interface which is simple with intuitive operation capability reduces confusion of an operator. When operating a complicated system, easy operations are required in each step of the operation. Also in teleoperation, in order to tell an operator the situation of workspace, it is necessary to display information by a suitable method. This paper proposes a teleoperating system using touch panel for two teleoperated mobile robots to improve the ease of operation and a method of calling operator's attention based on image processing.
