Abstract: Provided are a cleaning robot for obtaining a map of an indoor space, and an operating method thereof. The cleaning robot may: search the indoor space at a first location of the cleaning robot by using at least one sensor; obtain a grid map including a searched area, which has been searched at the first location, and at least one unsearched area, which has not been searched at the first location; determine, as a travel destination, a first unsearched area among the at least one unsearched area based at least in part on a distance from the first location; obtain area information including at least one of geometry information, structure information, or obstacle information about the first unsearched area while moving the cleaning robot to the determined first unsearched area; and update the grid map by using the obtained area information.

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.
