Abstract
A mobile robot calling system has a mobile robot normally waiting at a home position and connected to an AC power supply such that its battery is charged by the AC power supply in the wait status, and a calling oscillator for generating a calling signal to the mobile robot. The calling signal is supplied from the calling oscillator to the mobile robot through indoor AC power supply wiring. Relay transmitters are respectively arranged for a plurality of AC receptacles to relay the calling signal. A controller is arranged to control a plurality of calling devices and robot waiting stations. The controller cyclically checks the robot calling states of the calling devices and robot wait status in the waiting stations. The controller generates a robot calling command to the waiting stations in accordance with the robot wait status in the waiting stations when the robot calling signals are generated from the calling devices.
