PROBLEM TO BE SOLVED: To provide a mobile robot that can continue operations even after moving beyond the reach of radio waves by autonomously returning within the reach of radio waves and can extend a communication range in cooperation with a plurality of mobile robots. SOLUTION: Mapping means 19 autonomously map radio statuses in advance at mobile robot introduction or in a standby state without an operation command, and store them in storing means 16. Returning means 17, after an operation in an area with a poor radio status, move the mobile robot to the nearest communication range according to the mapping information. When another mobile robot enters an area with a poor radio status, radio relaying means 12a amplify field strength to extend the communication range, so that an operator and the mobile robot in the communication-disabled area can communicate. The radio relaying means may be replaced with command relaying means. COPYRIGHT: (C)2005,JPO&NCIPI
