Abstract
A mapping method includes: acquiring first map information created in advance, including information about a surrounding area of a mobile robot; acquiring second map information including information about the surrounding area by a sensor of the mobile robot; receiving third map information including information about the surrounding area from an environmental sensor node; (i) in the third map information, if a place exists in which an amount of change over time is equal to or greater than a certain threshold value, removing information about the place in each of the first and the second map information corresponding to that place, or alternatively, increasing the variance of information about the place in each of the first and the second map information corresponding to that place; and (ii) creating map information using the first and the second map information subjected to the removal or the variance increase.
