The advancement of automation in agriculture is critical in addressing the growing concerns of labor shortages, overuse of pesticides, and the health hazards faced by farmers due to manual spraying methods. In response to these challenges, the development of a Bluetooth-controlled agricultural pesticide spraying robot car offers a sustainable and low-cost solution. This paper reviews the design, implementation, and performance of a robotic spraying system that leverages embedded systems and wireless communication to control pesticide distribution efficiently. The system uses an Arduino UNO microcontroller, DC motors, servo motors, Bluetooth communication via an HC-05 module, and a 12V DC water pump to execute spraying functions precisely. The robot is controlled using an Android application, allowing farmers to manage the direction, movement, and spray mechanism remotely. This reduces direct contact with harmful chemicals, optimizes pesticide usage, and enhances spraying accuracy. Through a comparative literature review and practical implementation, this paper highlights the impact of such low-cost robotic innovations in revolutionizing small to mid-scale farming practices.
