Patent attributes
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.
