A Review of the Current Unmanned Aerial Vehicle Sprayer Applications in Precision Agriculture

Highlights A comprehensive review of the current Unmanned Aerial Vehicle Sprayer in precision agriculture applications. Comparison manned and unmanned aerial sprayers agriculture. Latest developments commercialized UAV available on market. Abstract. Vehicles (UAVs) are becoming more broadly used for improving agricultural spraying However, compared with nearly 100 years data accumulated applications, relatively new, associated technologies early stages development. The objective this paper is to give a platforms comparison discussion their application, performance, efficiency. total 213 peer-reviewed non-peer-reviewed articles, extension papers, government websites, company websites were reviewed cited study. We also discuss factors that could influence effectiveness such as release height, wind speed, vortex strength, droplet size. Finally, we latest worldwide present technology gaps those platforms. highlight areas require improvement, particularly autonomous navigational controllers systems.
