Abstract

 Agricultural activities such as seed sowing, irrigation and crop cutting often require repeated manual work and the use of separate tools. The project presents an Automated Agri Robot that combines these operations on a single mobile platform. The prototype integrates a seed-dispensing mechanism, a water-sprinkling unit and a motor-driven crop-cutting arrangement. An Android application developed using MIT App Inventor allows the user to control the robot wirelessly, which are communicated through an ESP8266 Wi-Fi module to a PIC16F877A microcontroller. The controller coordinates the output devices through a ULN2803A driver and relay circuit. A 12 V, 9 Ah rechargeable battery supplies the system, while a small solar photovoltaic panel is included to demonstrate renewable-energy support. The design is intended to reduce repetitive manual effort, simplify the operation of basic farming tasks and provide a compact, low-complexity prototype for small-scale agricultural applications. The report describes the system architecture, hardware, software, operating sequence and prototype outcome. Performance figures such as field coverage, seed-spacing accuracy, water-use efficiency and battery endurance require further experimental measurement.
