The main objective of this project is to design and develop a solar powered vehicle with a GH311 ultrasonic-based obstacle avoidance robot capable of moving autonomously while avoiding obstacles in its path. The system is designed using a PIC microcontroller, which controls the overall operation of the robot. A solar panel is used to generate electrical energy from sunlight, and the generated power is stored in a rechargeable battery through a charging circuit. The stored energy is then supplied to the motor driver and other electronic components of the robot. The GH311 ultrasonic sensor continuously measures the distance between the robot and nearby objects by transmitting ultrasonic waves and receiving the reflected echoes. When an obstacle is detected within a predefined distance, the PIC microcontroller processes the sensor data and sends control signals to the motor driver, which changes the direction of the robot to avoid collision. The robot moves automatically without human intervention, providing safe and efficient navigation in indoor and outdoor environments. An LCD display is used to show the status of the robot and obstacle detection information, while LED indicators provide visual indication of system operation. The proposed system demonstrates the effective integration of solar energy, ultrasonic sensing, motor control, and embedded technology to create an energy-efficient and environmentally friendly autonomous robotic vehicle. The project is suitable for applications such as smart transportation, surveillance, warehouse automation, educational robotics, and agricultural field monitoring, where autonomous obstacle avoidance and renewable energy utilization are required.
