The main aim of this project is to design and develop a solar-powered multipurpose agricultural robot to perform various agricultural operations such as ploughing, seed sowing, water spraying, and robot movement. The proposed system uses solar energy as a renewable power source to charge the rechargeable battery, thereby reducing dependency on conventional power sources and supporting sustainable agricultural practices. The system uses a PIC microcontroller as the main controlling unit. An ESP8266 Wi-Fi module is interfaced with the PIC microcontroller to establish wireless communication with the JUICE mobile application. Through the mobile application, the user can remotely control the robot and its agricultural operations. Two DC motors are connected through an L293D motor driver to control the forward, backward, left, and right movements of the robot. A seed-sowing mechanism is implemented using a separate DC motor controlled through a relay driver. When the motor is activated, the seed-dispensing mechanism rotates and releases seeds onto the soil. A water pump is also interfaced with the microcontroller through a relay to perform water spraying based on the commands received from the mobile application. Additionally, a plough tool is attached to the robot body to perform soil ploughing during movement. A solar panel is connected to the rechargeable battery through a charging circuit to provide renewable energy for operating the system. A regulated 5V DC supply is provided to the control circuit. A crystal oscillator is used to generate clock signals for the PIC microcontroller, while a reset button and LED indicators are provided for system operation and status indication. The entire system is programmed using Embedded C language to control the different operations. Thus, the proposed solar-powered multipurpose agricultural robot provides an efficient and eco-friendly solution for performing essential agricultural activities, reducing manual labour, and improving agricultural productivity.
