機体操向を行う必要がある。 For example, when performing circular mowing work, the machine must be oriented using a pivot turn method with a large turning radius to avoid contact between the machine body and the crop until it reaches the corner where the row of crops breaks, which could lead to incorrect operation. If the machine is oriented using a spin-turn method, the machine body may come into contact with the crops and damage the crops, or the position between the machine body and the crops to be harvested may change significantly, reducing work efficiency. Furthermore, when the aircraft reaches a corner, it is necessary to use an appropriate pivot turn method to improve work efficiency, or a spin turn method with a small turning radius to speed up the turn.
