Because application level and market demand are not equal among all the drones, marketing strategy should be different among drones. Key elements of the Fourth Industrial Revolution is to be used for market creation. Multiple sensor fusion, autonomous drone by deep learning, data collection drone of artificial intelligence technology, and IoT and big data analysis technology are need.
