The Multi-Purpose Agriculture Robot is designed to perform various agricultural operations such as ploughing, seed sowing, watering, and land leveling to reduce manual labour and improve farming efficiency. The robot consists of a long metal-fabricated body with a ploughing tool attached to the front side and a leveling tool attached to the backside of the robot. The system uses a PIC microcontroller as the main control unit and a Bluetooth module to receive commands from an Android mobile application. The robot movement is controlled wirelessly through the mobile application in forward, reverse, left, and right directions. The seed-sowing mechanism and water pump can also be independently controlled through the Bluetooth application. When the seed command is given, the microcontroller activates the seed-sowing motor to release seeds into the soil. Similarly, when the watering command is selected, the microcontroller switches ON the water pump to spray water on the agricultural field. A motor driver is used to control the DC motors responsible for robot movement, while relay circuits are used to operate the seed-sowing motor and water pump. A battery supplies power to the robot, and a 5V DC supply is provided to the control circuit. LED indicators are used to indicate the system operation. The proposed system provides a simple, low-cost, and user-friendly agricultural solution for small-scale farmers. By integrating multiple farming operations into a single robot with wireless Bluetooth control, it reduces human effort, saves time, and improves the efficiency of agricultural activities.
