Abstract

Unmanned aerial vehicles (UAVs) are being used more frequently for agricultural spraying as a
result of their effectiveness and precision. This project involved building a quadcopter without sensors,
cameras, or GPS for agricultural spraying. The quadcopter was created to rapidly and effectively cover a sizable
amount of agricultural land, while also minimizing the usage of pesticides and the impact on the environment.
The quadcopter's frame, which was made of lightweight materials to give strength and durability while
minimizing the aircraft's overall weight, was used in its construction. The quadcopter's frame was made to
accommodate four brushless motors, each of which had a propeller to give lift and movement. Four electronic
speed controllers (ESCs) were used to control the motors' rotational speed and direction. The high-capacity
lithium-polymer (LiPo) battery used by the quadcopter has sufficient power to run the motors and spraying
system continuously. A tank, a pump that pressurized the liquid, and a nozzle that released the pressurized
liquid over the crops as a fine mist made up the spraying system. A KK 2.1.5 circuit board served as the
foundation for the flight control system, which was wired to the battery, four ESCs, and other components.
The quadcopter's circuit board was configured to retain its position and altitude while flying steadily.
Additionally, it provided buttons and an LCD panel for the user to use to change flying characteristics
including the throttle, pitch, and roll. A handheld radio transmitter that interacted with a quadcopter receiver
was used to control the aircraft.
