Abstract: Disclosed are a robot cleaner and a method for controlling same. The robot cleaner comprises: a travel unit for moving a main body; a communication unit for communicating with a remote control device by using ultra-wideband signals; and a control unit which, in response to a first optical signal emitted from the remote control device to the main body, calculates the position of the remote control device by using the ultra-wideband signals that are output to the communication unit. Also, the control unit recognizes, in response to a second optical signal emitted from the remote control device directly after the first optical signal, the position of a target point corresponding to the second optical signal and calculated on the basis of the determined position of the remote control device, and generates a travel command to move the main body to the recognized position of the target point.
