  • Publication number: 20190339713
    Abstract: 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.

  • Publication number: 20190339715
    Abstract: 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.

  • Publication number: 20190339714
    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.

  • Publication number: 20190339711
    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.

  • Publication number: 20190155299
    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.
