Abstract: A mobile robot according to an embodiment of the present disclosure may include a traveling unit configured to move a 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 moving of the another mobile robot to follow along a moving path of the main body based on the recognized location. In addition, the controller may transmit a signal corresponding to a change of the moving direction to the main body in response to the change of the moving direction, and sense a change in the receiving direction of the signal according to the change of moving direction to transmit a control command for restricting the follow-up to the another mobile robot.

Abstract: Disclosed are a moving robot and a control method thereof, and the moving robot comprises a floor sensing unit comprised of a plurality of transmitters, for which different sensing distances are set, and a single receiver, and, since a floor state is sensed using a plurality of sensors, it is possible to sense a normal floor states, an obstacle or a cliff present on a floor, and a long-distance state at a distance farther than the normal floor state, thereby preventing wrong sensing of a cliff due to an obstacle, and, since whether to keep traveling is set depending on the obstacle and a traveling speed is controlled, even an area previously not allowed to enter due to the wrong sensing may be cleaned and therefore a cleaning area may be increased.

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.

Abstract: A plurality of autonomous mobile robots include a first mobile robot and a second mobile robot. The first mobile robot is provided with a plurality of transmitting optical sensors for outputting light and a first module for transmitting and receiving a Ultra-Wideband (UWB) signal. The second mobile robot is provided with a plurality of receiving optical sensors for receiving light and a second module for transmitting and receiving the UWB signal. A control unit of the second mobile robot determines an angle at which the first mobile robot is located with respect to a front of the second mobile robot using the light. The control unit also determines a distance from the second mobile robot to the first mobile robot using the UWB signal, and determines a relative position of the first mobile robot based on the angle and the distance.

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.
