Development of a Precision Agricultural Based Unmanned Aerial Vehicle for Pest Control

An aircraft that flies without a human pilot, other crew members, or passengers is referred to as an unmanned aerial vehicle (UAV), also referred to as a drone. The parts of an unmanned aircraft system (UAS) are unmanned aerial vehicles (UAVs). Similar to remotely piloted aircraft (RPA), UAVs can be flown remotely by a human controller, or with progressively higher levels of autonomy, such as autopilot support, all the way up to fully autonomous aircraft that require no human input. In a manner similar to remotely piloted aircrafts (RPA), UAV flight can be remotely controlled by a human operator. It can also be fully autonomous, meaning that no human input is required, or it can fly with varying degrees of autonomy, such as autopilot assistance. Drones are categorized based on their intended use, including drones for surveillance, aerial mapping, and photography. However, aerial platforms are the basis for the best classification of “drones. ” According to the aerial platform used, there are four main categories of drones: multi-rotor drones, fixed-wing drones, single-rotor helicopters, and fixed-wing hybrid VTOLs. In this work, a prototype of an unmanned aerial vehicle (UAV) that can spray liquid pesticides or weed-control agents on crops on agricultural farms was developed. This was done by creating a semi-autonomous quadcopter with a precision agriculture spraying system that includes a tank, pump, camera, and nozzles.
