Mobile robot system and method of controlling the same

A method of controlling a mobile robot system, the method comprising:

• at a mobile robot, transmitting a signal when cleaning of a traveling region is completed;
• determining whether the signal transmitted from the mobile robot is sensed within a restricted Field-of-View (FOV) of a beacon or as an approach signal;
• at the beacon, transmitting a guide signal to the mobile robot if the signal transmitted from the mobile robot is sensed within the restricted FOV;
• and
• performing movement navigation on a basis of the guide signal, wherein the performing of movement navigation on the basis of the guide signal includes guiding the mobile robot to cross a confinement border of the traveling region and to move to another region.
