  • Patent number: 11106210
    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.

  • Publication number: 20190314991
    Abstract: A robot movement control method includes: acquiring position information about two adjacent obstacles located on two sides of a robot along the robot moving direction or a perpendicular direction to the movement direction, and calculating distance therebetween; determining whether the distance is greater than a first pre-set distance; defining a virtual obstacle boundary between the two adjacent obstacles if the distance therebetween is not greater than the first preset distance; and controlling movement paths of the robot by means of the virtual obstacle boundary.
