In the last decade, we have witnessed the boom in the production of drones, that are unmanned aircraft. The exponential growth of the presence of drones in our skies is mainly due to their constant technological advancement and to the fact that their applications have increasingly diversified and are continuing to do so at an impressive rate. Today drones no longer have only military or modeling purposes, but they have proved to be very useful, sometimes indispensable, in many other contexts, among these we find agriculture, public order, filmography, photography and recently they are developing drones for the delivery of goods.
