This paper introduces an autonomous pesticide spraying robot designed for precision agriculture applications. With the escalating demand for sustainable farming practices, the need for efficient pest management solutions has become paramount. The proposed robot employs a combination of advanced technologies, including artificial intelligence, robotics, and sensing capabilities, to optimize pesticide application while minimizing environmental impact. Through real-time data collection and analysis, the robot identifies pest-infested areas and precisely administers the required amount of pesticide, thereby reducing chemical usage and increasing crop yield. Additionally, the robot's autonomous navigation system enables it to manoeuvre through complex terrain with minimal human intervention, enhancing operational efficiency and reducing labor costs. The integration of Internet of Things (IoT) connectivity facilitates remote monitoring and control, allowing farmers to manage spraying operations and receive actionable insights for decision-making remotely. Overall, the autonomous pesticide spraying robot represents a promising solution for sustainable agriculture, offering increased productivity, reduced environmental footprint, and improved crop health.
