Building a Solar Tracker Robot Controlled by the ZedBoard FPGA Board

This work presents how to build a robot who tracks the Sun. Solar tracker robots are used to track the position of the Sun. Rotating solar panels towards the Sun can increase their efficiency considerably. Tracking the Sun can be done with photoresistors or pirheliometric sensors. Rotating solar panels towards the Sun can be done with servomotors. The control of the system can be done with a development board, which in our case is a Digilent ZedBoard with an Artix 7 FPGA. The solar tracker robot is controlled using a tracking algorithm which ca be extended to rotate wind turbines in the direction of the wind just by interchanging the photoresistors or pirheliometric sensors with wind sensors or anemometers.
