An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without any human pilot, crew, or passengers on board. UAVs were originally developed through the twentieth century for military missions too "dull, dirty or dangerous"[1] for humans, and by the twenty-first, they had become essential assets to most militaries. As control technologies improved and costs fell, their use expanded to many non-military applications.[2] These include aerial photography, area coverage,[3] precision agriculture, forest fire monitoring,[4] river monitoring,[5][6] environmental monitoring,[7][8][9][10] policing and surveillance, infrastructure inspections, smuggling,[11] product deliveries, entertainment, and drone racing.
