Abstract: A cleaning robot capable of entering a region under an obstacle and cleaning by reducing a height of a LiDAR sensor, and a control method thereof are provided. The cleaning robot includes a main body, a driving device, a cleaning device, a LiDAR sensor and configured to be raisable and lowerable between a first position and a second position having different heights, a bumper sensor configured to detect a collision between the LiDAR sensor and an obstacle, an obstacle sensor configured to obtain information on an obstacle, and a processor configured to generate a cleaning map based on an output of the LiDAR sensor and an output of the obstacle sensor, and control the sensor driver to adjust a height of the LiDAR sensor based on at least one of the cleaning map, an output of the bumper sensor, or the output of the obstacle sensor.

Abstract: A robot includes; a driving module, a communication module, and at least one processor configured to receive, a second docking guidance signal output from a second docking station; determine a first output time of the received second docking guidance signal, determine a second output time of a first docking guidance request signal to be transmitted based on the determined first output time to prevent the first docking guidance request signal from overlapping with the second docking guidance signal, and output the first docking guidance request signal, through the communication module, based on the determined second output time of the first docking guidance request signal, and in response to the outputting of the first docking guidance request signal, receive, a first docking guidance signal, docking the robot to the first docking station by driving the driving module in response to receiving the first docking guidance signal.
