Abstract: Provided is a robot including: a body rotatable about a first shaft; a first drive wheel and a second drive wheel provided in the body to be rotatable about a second shaft that is perpendicular to the first shaft; at least one distance sensor provided on the second shaft; and a processor. The processor may acquire first distance information through the at least one distance sensor at each of a plurality of different points at which the body is located as the body moves; acquire second distance information through the at least one distance sensor in each of a plurality of different directions in which the body is directed as the body rotates; and acquire, based on the first distance information and the second distance information, acquire information about a location point of the robot on a map corresponding to a space in which the robot is located.

Abstract: A robot includes: at least one memory storing first map data corresponding to a first region of a specific space; a distance sensor configured to acquire distance data while the robot travels in the specific space; and at least one processor operatively connected to the at least one memory and the distance sensor. The at least one processor is configured to: based on second map data acquired based on the distance data, compare the first map data and the second map data and generate a comparison result, and based on identifying, based on the comparison result, that an error does not exist in the second map data and that the second map data comprises information on a second region, update the first map data with the second map data.
