Abstract
View PDFTree climbing plays an important role in agricultural activities such as pesticide spraying on tall arecanut and coconut trees. This project presents a Tree-Climbing Robot for Pesticide Spraying, designed to reduce physical effort and safety risks associated with manual tree climbing. The robot consists of two gripping segments connected by a threaded rod, which is driven by a high-torque, low-speed DC motor to achieve inchworm-like climbing movement. An ATmega8 microcontroller controls the motors, while L293D motor drivers, a current sensor, contact sensors, and an RF transmitter-receiver system support controlled gripping and remote operation. The robot performs upward and downward movements through coordinated gripping and releasing actions of both segments. This system provides an alternative approach to pesticide spraying on tall trees and aims to improve agricultural safety and reduce dependence on hazardous manual climbing activities. The project contributes to Sustainable Development Goal 8 (SDG 8): Decent Work and Economic Growth.
