Abstract
A moving robot and a controlling method thereof are disclosed. A moving robot according to the present disclosure includes a traveling unit to move a main body, a communication unit to communicate 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, and to control the traveling unit to move the main body without departing from the boundary. The communication unit includes first and antennas provided at respective transceivers that transceive signals with the location information transmitter, and the first and second antennas have an adjustable distance. When signals are received through the first and second antennas, the control unit determines a relative location of the location information transmitter based on a current location of the main body using a frequency corresponding to the distance between the first and second antennas.
