Abstract: A robot cleaner includes a main body, a traveling unit, a cleaning unit, a sensor unit, and a controller. The traveling unit allows the main body to travel. The cleaning unit suctions foreign substances around the main body during the traveling. The sensor unit is rotatable and senses an obstacle using light reflected or scattered by the obstacle. The controller controls the traveling unit so as to travel along a traveling path and controls the cleaning unit so as to perform cleaning. Here, the sensor unit includes a first mode and a second mode that are set to differ from each other in sensitivity with respect to the reflected or scattered light, and the controller changes the sensitivity of the sensor unit according to a traveling mode.

Abstract: A moving robot including: a lidar sensor to acquire terrain information; a memory to store node data nodes; and a controller to determine whether at least one open movement direction exists based on sensing data of the lidar sensor and the node data, to generate a new node in the node data and add the generated node to a node group, to determine any of the open movement directions as a movement direction, to control the robot to travels an area corresponding to the node group, to control a suction unit to suck foreign matter around the main body when traveling in the node group, to initialize the node group, to determine whether at least one node is to be updated, moving the robot to any one of the nodes to be updated, and to complete generation of a map.

Abstract: A mobile robot of the present disclosure includes: a traveling unit configured to move a main body; a cleaning unit configured to perform a cleaning function; a sensing unit configured to sense a surrounding environment; an image acquiring unit configured to acquire an image outside the main body; and a controller configured to generate a distance map indicating distance information from an obstacle for a cleaning area based on information detected and the image through the sensing unit and the image acquiring unit, divide the cleaning area into a plurality of detailed areas according to the distance information of the distance map and control to perform cleaning independently for each of the detailed areas. Therefore, the area division is optimized for the mobile robot traveling in a straight line by dividing the area in a map showing a cleaning area.
