Document Type and Number:
WIPO Patent Application WO/2023/195621
Kind Code:
A1
Abstract:
Provided in an embodiment of the present invention for accomplishing the objective is a mobile robot control method comprising the steps of: collecting traveling state information while traveling in a traveling zone according to a basic map of the traveling zone; analyzing the traveling state information so as to set, as a dangerous region, a position where a plurality of abnormal situations occur, thereby creating a prohibited region map in the traveling zone; overlapping the predetermined number of prohibited region maps so as to calculate prohibited region candidates, if the prohibited region map is created to satisfy a predetermined number; and reflecting at least one of the prohibited region candidates on the basic map as a prohibited region so as to update the basic map to be used for subsequent traveling in the traveling zone. Therefore, various abnormal situations that cannot be sensed by a sensor for a space in which traveling is necessary can be recognized, and the type of situation, from among restriction, wandering and collision, can be accurately recognized according to various determination schemes and can be handled according thereto.
