When the tele-operated mobile robot went over its communication range accidentally, the operation would be suspended. We named this kind of trouble "the distress of mobile robot". In order to prevent the distress of mobile robot, it is necessary to estimate communications conditions around the robot by means of radio wave propagation simulation. It is thought that the robot by means of radio wave propagation simulation about the indoor environmental uses the model who settled a plan of building for the cause. However, plan of building may be different from true environment, because many building are given equipment, enlargements and rubble. They can obstacle to the robot and the communication. In this paper, we simulated radio wave propagation on some indoor environment models. We compared that results and considered that obstacle effects tele-operated mobile robot.
