Robot and map generation method thereof

A map generation method of a robot, the map generation method comprising:

• obtaining a guide map for guiding map generation and storing the guide map in memory of the robot;
• converting the guide map into a map form recognizable by the robot;
• identifying a search boundary determined based on the map form;
• generating, based on a sensing value of a sensor of the robot, a sensing map of a space in which the robot moves as the robot moves within the search boundary;
• and
• matching the guide map with the sensing map and generating a space map of the space.

A non-transitory computer-readable storage medium storing computer instructions that, when executed by a processor of a robot, cause the robot to perform operations, the operations comprising:

• obtaining a guide map for guiding map generation and storing the guide map;
• converting the guide map into a map form recognizable by the robot;
• identifying a search boundary determined based on the map form;
• generating, based on a sensing value sensed by a sensor of the robot, a sensing map of a space in which the robot moves as the robot moves within the search boundary;
• and
• matching the guide map with the sensing map and generating a space map of the space.
