Title:
薬剤散布用無人マルチコプター、ならびにその制御方法および制御プログラム
Document Type and Number:
Japanese Patent JP6733949
Kind Code:
B2
Abstract:
[Problem] To provide a chemical spray drone (an unmanned aerial vehicle) which minimizes unwanted chemical spraying outside of the agricultural field. [Solution] Downward air currents of the rotor are actively used to minimize spraying of chemicals outside of the target location. A two-stage rotor which rotates in mutually opposite directions may optionally be used. Furthermore, the chemical discharge amount, flight speed, altitude and nozzle position are adjusted depending on change in parameters such as rotor speed, the total weight of the aircraft, etc. It is preferable to stop chemical spraying when the speed difference between the upper and lower rotors of the two-stage rotor has exceeded a prescribed value. Additionally, it is preferable to adopt a propeller guide having a shape that can reduce air resistance of the downwards air flow.
