Unmanned Aerial Vehicles (UAVs) are currently one of the most promising frontiers of technological development for our society. Some applications of this technology have been in use for a long time in military scenarios and in specific civil applications but only in recent years drones achieved a significant market diffusion. Unfortunately, their employment is still restricted by some constraints, limiting their applicability in many industrial environments. These limitations are mainly related to the safety and reliability of UAVs and to the management and acquisition of sensitive data in terms of privacy. In order to enhance the market diffusion of UAVs, scientific research can optimise their technical characteristics, making them both a safer, more reliable technology and an optimally performing solution for completing specific missions and industrial tasks.
