Development of A Solar Operated Smart Multi-Functional Agribot

The Multipurpose Agricultural Robot is a compact and multifunctional farming machine designed to automate key agricultural operations such as grass cutting, seed sowing, and spraying of water, manure, weedicide, or pesticide. The robot is built on a rigid mild steel chassis and uses a 4-wheel drive system powered by 12V DC wiper motors to ensure stable locomotion on agricultural terrains. In addition to its operating functions, the robot is equipped with a 20-watt solar panel that charges the onboard battery, enabling partial energy independence and reducing dependence on external electrical sources. Grass cutting is performed using a high-speed RS-775 motor, while seed sowing is achieved through a mechanically driven metering shaft with drilled holes to dispense seeds uniformly. The entire system is controlled wirelessly using an Android smartphone via Bluetooth and an Arduino UNO microcontroller. This project aims to reduce manual labor, operational cost, and environmental impact while improving agricultural efficiency.
