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.

Abstract: A mobile robot includes a communication unit that communicates with another mobile robot, a sensing unit for sensing the other mobile robot existing in a detection area encompassing a predetermined projected angle with respect to the front of a main body of the mobile robot, and a control unit configured for rotating the main body so that the other mobile robot is sensed in the detection area. The communication unit transmits a control signal configured to cause the other mobile robot to travel in a linear direction by a predetermined distance, to the other mobile robot when the other mobile robot is present in the detection area.

Abstract: A plurality of autonomous mobile robots includes a first mobile robot provided with a transmitting sensor for outputting sound wave of a first frequency, and a first module for transmitting and receiving a signal of a second frequency higher than the first frequency. A second mobile robot is provided with a receiving sensor for receiving the sound wave of the first frequency and a second module for transmitting and receiving the signal of the second frequency. A control unit of the second mobile robot synchronizes an output time of the sound wave of the first frequency from the first mobile robot using the signal of the second frequency, and determines a relative position of the first mobile robot using the sound wave of the first frequency.
