Plurality of autonomous mobile robots and controlling method for the same

A mobile robot, comprising:

• a traveling unit configured to move or rotate a main body;
• a communication unit configured to perform communication with another mobile robot;
• a sensing unit configured to sense the other mobile robot existing in a detection area having a predetermined angle with respect to the front of the main body;
• and
• a control unit configured to rotate the main body so that the other mobile robot is sensed within the detection area, and configured to control the communication unit to transmit a control signal to the other mobile robot, the control signal configured to cause the other mobile robot to travel in a linear direction for a predetermined distance, when the other mobile robot is present in the detection area,
• wherein the control unit is configured to determine a relative position of the other mobile robot and a direction that the other mobile robot faces, based on the linear travel of the other mobile robot for the predetermined distance, and control the communication unit to transmit a control signal to the other mobile robot to cause the other mobile robot to move to a specific point within the detection area, based on the relative position of the other mobile robot and the direction that the other mobile robot faces.
