Title:
ROBOT AND ROBOT CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2023/132638
Kind Code:
A1
Abstract:
A robot and a robot control method are disclosed. The robot comprises: a lidar sensor; a driving unit; a memory storing first map data corresponding to a first traveling space; and a processor for: acquiring sensing data through the lidar sensor at the traveling start position of the robot; controlling the driving unit so that the robot travels when a position corresponding to the traveling start position of the robot is not identified on the first map data on the basis of the acquired data; acquiring second map data on the basis of sensing data acquired through the lidar sensor while the robot is traveling; identifying whether a second traveling space corresponding to the second map data matches the first traveling space on the basis of probability information, which is included in the first map data, and object position information, which is included in the second map data; and identifying the traveling start position of the robot on the first map data on the basis of the traveling start position of the robot and the object position information on the second map data when the second traveling space is identified as matching the first traveling space.
