Development Of Wing-Type Pesticide Spraying Robot for Agriculture.

Abstract

The rapid growth of precision agriculture, autonomous robotics, and intelligent farming technologies has significantly transformed modern agricultural practices. Conventional pesticide spraying methods often expose farmers to harmful chemicals, result in uneven chemical distribution, increase pesticide wastage, and reduce overall spraying efficiency. In addition, manual spraying techniques require high labor effort and frequently lead to environmental contamination due to uncontrolled chemical application. To address these challenges, this research proposes the development of a wing-type pesticide spraying robot designed for efficient, autonomous, and precision-based agricultural spraying operations. The proposed robotic system integrates intelligent navigation, wing-type spray distribution mechanisms, obstacle detection sensors, automated pump control, and IoT-assisted monitoring to improve spraying accuracy and operational efficiency. The wing-based spraying structure enables wider spray coverage and uniform pesticide distribution across agricultural fields while minimizing chemical loss and human exposure. The robot utilizes embedded controllers, motorized wheel mechanisms, ultrasonic sensors, and programmable spray systems for autonomous field navigation and adaptive pesticide application. Experimental analysis demonstrates that the proposed robotic platform significantly improves spraying uniformity, reduces pesticide consumption, minimizes labor dependency, and enhances agricultural productivity compared to traditional manual spraying systems. The proposed system provides a cost-effective, scalable, and environmentally sustainable solution for smart farming and next-generation precision agriculture applications.
