Smart Pesticide Spraying Robot

Abstract: The Smart Pesticide Spraying Robot aims to make agricultural spraying safer, more efficient, and less labour-intensive. Traditional pesticide spraying requires significant manual effort, exposing farmers to harmful chemicals and causing pesticide wastage due to uneven distribution. This project presents a semi-autonomous robot that can be operated manually or remotely through a wireless control module. The system integrates DC motors, a motor driver circuit, and an electric pump to ensure uniform pesticide spraying across the field. The robot moves on wheels and can be controlled from a safe distance, minimizing direct human contact with chemicals. The main objectives are to optimize pesticide usage, improve spraying efficiency, and enhance operator safety. Experimental results indicate that the automated spraying process effectively reduces labour, saves time, and supports sustainable farming practices.
