Abstract

A mobile robot of the present disclosure includes a first pattern emission unit configured to emit a first patterned light downward and forward from the main body on a floor of an area to be cleaned; and an image acquisition unit configured to acquire an image of first patterned light emitted by the first pattern emission unit and is incident on an obstacle, so as to determine an obstacle based on a pattern detected from the acquired image. Accordingly, based on the information on the nearby obstacles, by determining whether the mobile robot is in a stuck state where traveling of the mobile robot is limited by a plurality of obstacles, and by setting up an escape for traveling, traveling state of the mobile robot and obstacles may be determined rapidly and a corresponding operation may be performed, thereby enabling effective traveling to escape from the stuck state.
