In recent years, modern precision agriculture techniques led to a rise in the use of Unmanned Aerial Vehicles (UAVs) for many different purposes, such as land survey, plant health monitoring and crop spraying. These vehicles are particularly suited for the use over rough and mountainous terrains or dispersed plots of land, that traditional land vehicles may find difficult to reach or too time consuming. UAVs can also benefit the farmers as they can be, and often are, automated in their operation, further increasing productivity while reducing the exposure to potentially hazardous chemicals. Politecnico di Torino, in collaboration with SEASTAR, started the research on "New technical and operative solutions for the use of drones in Agriculture 4.0" through a grant linked to the PRIN 2017 (\textit{Progetti di ricerca di Rilevanza Nazionale}, Research projects of national interest), a program of the Italian Ministry of Education, University and Research.
