Classification: CPC A  B | IPC A  B

Claim 13:
14. A moving robot system, comprising:
a plurality of transmitters installed in a boundary area of a travel area and configured to transmit one or more signals; and
a moving robot that determines a position based on a reception result of the transmitted signals,
wherein each of the plurality of transmitters comprises:
a support module provided on a bottom surface of a main body and configured to be driven into a ground surface to support the main body;
a detection module provided on the bottom surface of the main body and configured to detect whether the main body is separated from the ground surface; and
a communication module in wireless communication with a communication target of the transmitter,

wherein the moving robot is configured to activate and deactivate a detection mode that is set in the moving robot for detecting whether at least one of the plurality of transmitters is removed,
wherein each of the plurality of transmitters is configured to detect whether the main body is separated from the ground surface when the detection mode is activated,
wherein each of the plurality of transmitters is configured to not detect whether the main body is separated from the ground surface when the detection mode is deactivated, and
wherein each of the plurality of transmitters generates a notification signal and transmits the notification signal to at least one of the moving robot and an adjacent transmitter when a corresponding detection module detects that the main body is separated from the ground surface.
