  • Publication number: 20170332862
    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.

  • Publication number: 20170336796
    Abstract: A mobile robot of the present disclosure emits a first patterned light downward and forward from a main body on a floor of an area to be cleaned and a second patterned light upward and forward from the main body, determines an obstacle based on an image of each emitted patterned light which is incident on the obstacle, and senses a tilt of the main body to compensate for the tilt. In this manner, an obstacle may be determined accurately, and after the tilt compensation, redetermination is made as to whether it is possible to pass through, so as to enable the mobile robot to pass through or bypass the obstacle. Accordingly, the mobile robot may reach a wider area to be cleaned, thereby extending the area that may be cleaned, and enabling fast determination and operation for effective traveling, such that the mobile robot may escape from an obstacle without being limited thereby.
