The present disclosure relates to a plurality of autonomous cleaners. A first cleaner of the plurality of autonomous cleaners according to one embodiment of the present disclosure includes a traveling unit to move a main body thereof, a communication unit to perform communication with a second cleaner, and a control unit to determine a position of the second cleaner using an Ultra-WideBand (UWB) signal output from the communication unit, and set area information, in which the first and second cleaners are to perform cleaning, based on a position of the first cleaner and the position of the second cleaner, wherein the control unit controls the second cleaner based on second area information in which the second cleaner is to perform cleaning.

Plurality of autonomous cleaner and controlling method for the same

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.

Robot cleaner and method for controlling same

A plurality of autonomous mobile robots includes a first mobile robot having a first module for transmitting and receiving an Ultra-Wideband (UWB) signal, and a second mobile robot having a second module for transmitting and receiving the UWB signal. The second mobile robot follows the first mobile robot using the UWB signal.

Plurality of autonomous mobile robots and controlling method for the same

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.

Plurality of robot cleaner and a controlling method for the same

A plurality of autonomous mobile robots includes a first mobile robot and a second mobile robot. The first mobile robot is provided with a transmitting optical sensor for outputting laser light, and a first module for transmitting and receiving an Ultra-Wideband (UWB) signal. The second mobile robot is provided with a receiving optical sensor for receiving the laser light and a plurality of second modules for transmitting and receiving the UWB signal. A control unit of the second mobile robot determines a relative position of the first mobile robot based on the received UWB signal and a determination of whether the laser light is received by the optical sensor.

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.

A 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.
