The main aim of this project is to design and develop a Bluetooth-controlled agriculture robot to reduce manual effort and simplify agricultural operations. The proposed system is designed to perform agricultural activities such as robot movement, grass cutting, and water spraying. The robot can be controlled wirelessly using an Android mobile phone through Bluetooth communication. The system uses a PIC microcontroller as the main controlling unit. An HC-05 Bluetooth module is interfaced with the PIC microcontroller to receive commands from the Android mobile phone. Based on the received commands, the microcontroller controls the movement of the robot in forward, backward, left, and right directions through an L293D motor driver connected to DC motors. A separate L293D motor driver is used to control the grass cutter and water motor according to the commands given by the user. The grass cutter is used to remove unwanted grass, while the water motor is used for spraying water on agricultural fields. A rechargeable battery is used to provide power to the system, and a regulated power supply (RPS) provides the required operating voltage to the control circuit. A crystal oscillator is used to provide clock signals to 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 perform the required control operations. Thus, the proposed Bluetooth-controlled agriculture robot provides a simple, low-cost, and efficient solution for performing basic agricultural operations with reduced human effort. Thus, the proposed solar-powered IoT-based multipurpose agriculture robot provides an efficient, cost-effective, and user-friendly solution for automating essential agricultural activities.
