Development of UAV Octocopter Based on Pesticides Spraying System

The application of pesticides in agriculture has a leading role in increasing the per acre yield of different crops. There are a number of systems through which pesticides can be sprayed on crops. Unmanned aerial vehicles (UAVs) are being progressively used for this purpose due to their improved efficiency and high-speed characteristics. This research work mainly focuses on the construction of an octocopter based on the idea of UAVs for the agriculture sector. The implementation of octocopter for spraying chemicals is prominently increasing to minimize the wastage of pesticides while increasing the production of crops. This research also strives to minimize the spraying time, labor cost and weight of the octocopter for its better utilization and implementation in the field of agriculture. The flight test showed that the octocopter is useful, efficient and beneficial for the intended application.
