DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for controlling a spraying amount and a spraying direction of a medicine (chemical solution, granules, etc.) spraying device mounted on a radio-controlled helicopter.

[0002]

2. Description of the Related Art Conventionally, a technique has been known in which a radio-controlled helicopter can be used to spray medicine in the air.

Therefore, the operation of changing the spray width becomes complicated, and it takes time to change the spray width and the spray direction. In addition, since it cannot be changed during the flight, an extra round-trip flight or an increase in the area of overlapping spraying may cause unnecessary flying or spraying work.

[0004]
