Abstract

Methods for angle correction of a mobile robot in a working area and mobile robots performing the same are disclosed. In one example, a long straight line is obtained at an edge of an obstacle first found by the mobile robot. A right-angle coordinate system is established based on the long straight line. A walking angle of the mobile robot is obtained when the mobile robot finds a long straight line at an edge of an obstacle again. Based on the walking angle and the right-angle coordinate system, the walking angle is corrected to a corresponding axis direction.
