1. A moving robot, comprising:
a traveling unit to move a main body thereof;
a communication unit to perform communication with a location information transmitter for transmitting signals within an area; and
a control unit to set a virtual boundary with respect to a location calculated based the signals of the location information transmitter, and to control the traveling unit so that the main body is moving without departing from the set boundary,
wherein the communication unit comprises a first antenna and a second antenna provided in respective transceivers that transmit and receive signals to and from the location information transmitter, and the first antenna and the second antenna have an adjustable distance therebetween,
wherein the control unit is further configured to:
adjust the distance between the first antenna and the second antenna, and
when signals are received through the first antenna and the second antenna, determine a relative location of the location information transmitter with respect to a current location of the main body using a frequency corresponding to the distance between the first antenna and the second antenna.
