  • Patent number: 12491641
    Abstract: A system and method for automatically correcting orientation of a mobile robot operating in a work area comprising a matrix of ground markers is provided. The system comprises a pattern formed in each of defined grids in the work area. The pattern defines a plurality of vectors converging towards the corresponding ground marker positioned in the respective defined grid. The system further comprises a processing unit configured to: receive the captured image from an optical recognizer provided in the mobile robot; process the captured image to check if any section of the pattern is visible therein and to determine any vector visible in the section of the pattern; and configure an odometry control arrangement of the mobile robot to reorient the mobile robot to follow a path in a direction of the determined one of the plurality of vectors.
