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 may include 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 the 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. In addition, the controller may control the moving of the another mobile robot to remove at least part of the stored trajectory information, and allow the another mobile robot to follow a moving path corresponding to the remaining trajectory information in response to whether the moving path corresponding to next trajectory information to be followed by the another mobile robot satisfies a specified condition.
