This project pretends to be a document that includes all the process of design and manufacture of a solar tracker. The solar tracker has its performance divided in three main parts; the first that gets information from the exterior. This project explains how the sensors that get the external information are chosen, the materials which are made of and how are they positioned. The second part, which analyses and process this information is done through a microcontroller, the document also includes all the microcontroller code with a detailed explanation of it. The last part explains how the solar tracker gives a response to this information and how the actuators effectively do it. As the project includes also de manufacture of the solar tracker all this must be subjected with a structure so it includes also a kinematic and a dynamic study of it. Moreover a batteries system is done in order to have an autonomous solar tracker capable to aliment itself and an external device. The document includes all the necessary steps to transform the electrical energy from the photovoltaic panels to charge the batteries and also the way the batteries charge the device. Finally an environmental viability of the project is done and an economic analysis that includes all the expenses of the project and a simulation of the economic viability of the project as if someone would decide to invest in the device. The project has a lot of parts and performs a lot of different branches of engineering, such as, electronic, mechanical or cost engineering.
