In this Final Degree Project, we have designed two unmanned aerial aircraft (drones) to read RFID tags (Radio Frequency Identification Systems), to use them in an application such as the stock control in a certain company. Our main purpose is to develop the capabilities of these drones to be able to fly above a region, read automatically these tags, which would be located in boxes or in objects in stock, and send their correspondent codes to a terrain base, where a computer should be able to process them. This process would lead to a reduction of time compared to the actual manual mode of lecture. First of all, the historical timeline of unmanned aerial vehicles and RFID systems have been studied. Moreover, we have analysed the basic concepts of electromagnetism, in order to understand the operation of the Radio Frequency Identification Systems. These systems contain different parts, which are described, and are capable to work at different frequencies, depending on the range that we need in the application. After these theoretical concepts, the block diagram has been defined for each of the two drones. The first one is a commercial Parrot Bebop Drone, useful to work inside and outside, in which we have introduced a RFID System that works at 125 kHz (low frequency), whilst the other one is a microdrone of development Crazyflie, with a reduced size, ideal for working indoor, and a RFID System of 13.56 MHz (high frequency). During the project, the advantages and disadvantages of each one have been exposed, as long as their possible applications. Then, we have proceeded to the election of each of the blocks defined previously, considering their characteristics and the desired application and, finally, we have put them together to design the systems, and we have configured the software needed. Following these steps, we have been able to develop completely the first system, the commercial drone which works at low frequency, and we have been able to verify its proper use.
