PROBLEM TO BE SOLVED: To prevent a mobile robot from moving to a place where radio waves do not reach and becoming unoperable, and to bring the robot back to a place where radio waves reach to restart the operations. SOLUTION: A radio device such as a wireless LAN card, a cellular phone or a Bluetooth(R) is connected to a mobile robot 1, and a user can remotely operate the mobile robot 1 via a network or can obtain the status of the mobile robot 1 on a terminal 2 of a personal computer or cellular phone. The mobile robot is equipped with a means for monitoring the radio wave status and returning the mobile robot to a spot where radio connection is possible, when radio waves do not reach to the movable robot while moving. Thus, even after the mobile robot moves to the place where radio waves do not reach, the operations can be restarted. Further, the mobile robot 1 is equipped with a means for creating a radio wave intensity map, and the map may also be used to bring the mobile robot back to the place where radio waves reach.
