Abstract - This paper presents the design and development
Automation and renewable energy technologies offer promising solutions to these problems. The use of robotic systems in agriculture can significantly reduce human effort while improving accuracy and consistency in field operations. At the same time, solar energy provides a clean, renewable, and widely available power source that is particularly suitable for agricultural environments. Integrating solar power with automated spraying systems can reduce dependence on fossil fuels and external electricity, making farming practices more sustainable and cost-effective.
of a solar-powered pesticide spraying robot intended for efficient and safe agricultural operations. The system comprises a solar panel, rechargeable battery, control unit, DC motor pump, pesticide tank, height-adjustable sprinkler sprayer, and a rocker–bogie-based motorized wheel mechanism. Solar energy is harnessed to charge the battery, which supplies power to the DC motors, pump, and remotecontrol receiver circuit. The rocker–bogie mechanism enables smooth and stable movement over uneven farmland, while remote control operation allows precise navigation without direct human exposure to harmful chemicals. The DC motor pump delivers pesticide from the storage tank to an adjustable sprinkler sprayer, ensuring uniform and controlled spraying suitable for different crop heights. The proposed robot operates independently of conventional power sources, reduces manual labor, minimizes pesticide wastage, and enhances farmer safety. Overall, this system offers an ecofriendly, cost-effective, and practical solution for modern agricultural pesticide application.
In this context, the solar-powered pesticide spraying robot presented in this work is designed to automate the spraying process while ensuring farmer safety and environmental sustainability. The system incorporates a solar panel, rechargeable battery, control unit, DC motor-driven pump, and a height-adjustable sprinkler sprayer to enable uniform pesticide application for different crops. A rocker–bogie mechanism with motorized wheels allows stable movement over uneven farmland, while remote control operation ensures safe and convenient navigation. This project aims to provide an efficient, eco-friendly, and practical solution for modern agricultural pesticide application.

2. LITERATURE SURVEY
1. INTRODUCTION
The increasing demand for precision agriculture and laborsaving technologies has stimulated extensive research into automated spraying systems. Early studies focused on mechanized boom sprayers and tractor-mounted systems that improved application uniformity over large fields but remained dependent on fuel and human operation. As smallscale and fragmented farms became more common, research shifted toward compact, mobile platforms capable of operating in tight spaces and reducing direct human exposure to chemicals.
Agriculture plays a vital role in the economic development of many countries, yet it continues to rely heavily on manual labor for essential operations such as pesticide spraying. Conventional spraying methods require farmers to carry heavy equipment and work in close contact with harmful chemicals, which can lead to serious health issues and uneven application of pesticides. In addition, the increasing cost of labor and limited access to reliable electrical power in rural areas create further challenges for efficient crop management.
