Claim 8:
9. A mobile robot, comprising:
a traveling unit configured to move a main body;
a memory configured to store trajectory information of a moving path corresponding to the movement of the main body;
a communication unit configured to communicate with another mobile robot that emits a signal; and
a controller configured to:
recognize a location of the another mobile robot based on the signal, and control the another mobile robot to follow a moving path corresponding to the stored trajectory information based on the recognized location,
determine whether first trajectory information stored in the memory satisfies a specified condition,
transmit a control command for moving the another mobile robot to a position corresponding to second trajectory information stored in the memory subsequent to the first trajectory information, wherein at least one intermediate trajectory information is included between the first trajectory information and the second trajectory information,
remove the first trajectory information and the least one intermediate trajectory information from the memory when the another mobile robot moves to the position corresponding to the second trajectory information,
remove all trajectory information in a current sector in response to satisfaction of the specified condition, and determine a next sector based on a current location and moving direction of the another mobile robot, and
control the moving of the another mobile robot to move on a path connected by a shortest straight line from a current location of the another mobile robot to a current location of the main body, instead of a moving path corresponding to the trajectory information of the main body detected for a predetermined period of time, in response to a change in the moving direction of the main body more than a reference number of times for the predetermined period of time.
