Most of the solar powered vehicles are powered using fixed solar panels placed on top of the vehicle, where the solar panel remains in the direction of vehicle irrespective of the direction of the sun. This project provides the best solution for this by aligning the tracker setup continuously toward the sun irrespective of the direction of the robot/vehicle. The project is PIC microcontroller based robot where the base of the robot can move in all directions and tracker-base itself will align the solar panel to track the sun exactly. Intelligent feedback is provided with the help of digital compass for perfect solar tracking. This project does not need any installation since it is portable and can be located in a free space exposed to direct sunlight. The use of solar energy for powering the robot makes the project distinctive. This project is mainly intended to design a mobile robot that is powered by a solar tracking system with an intelligent feedback system. The project is implemented using PIC microcontroller, H-Bridge motor drivers, LDR sensors, and digital compass and a tracker setup.
