Provided is a lawn mower for forming images. The lawn mower includes: an image input unit receiving an image to be formed in a lawn area; a position detection unit detecting position information of the lawn mower on a movement path of the lawn mower; a lawn mowing unit processing a lawn according to any one of a plurality of lawn processing patterns which corresponds to each position on the movement path while the lawn mower moves along the movement path; and a control unit analyzing the image received from the image input unit, determining a lawn processing pattern, which corresponds to the position information detected by the position detection unit, to express the image in the lawn area and controlling the lawn mowing unit according to the determined lawn processing pattern and independently of the movement path.

Lawn mower for forming images

Provided is a method and apparatus for controlling the precision of the rotation angle of a rotation of a dynamic apparatus, including the step of determining a conversion factor of a gyroscope installed in the dynamic apparatus to control the rotary movement to be a first conversion factor; a first step of measuring an output angular velocity in the case of applying a predetermined test operation to the gyroscope; a second step of measuring a second conversion factor based on the test operation and the output angular velocity corresponding to the test operation; a third step of computing an error between the first conversion factor and the second conversion factor; and a fourth step of updating the first conversion factor of the gyroscope by the second conversion factor in the case the error is more than a predetermined standard value, wherein in the case the dynamic apparatus is on standby or an operation command with respect to a predetermined operation is inputted, the first through fourth steps are performed before the operation is performed.
