Abstract: An Unmanned Aerial Vehicle (UAV) is reusable, consisting of power system and unmanned autopilot controller; while a Unmanned Aircraft System (UAS) is a system controlled manually, automatically or independently to perform different kinds of tasks This article summarizes and analyzes the characteristics of UAV and UAS in different historical stages; secondly, this article emphasizes UAV and UAS requirements for Artificial Intelligence technologies; finally, this article discusses potential influences on UAS. A UAS usually consists of UAV platforms, payloads for tasks, datalink devices, information processing devices, and integrated support equipment. Research on UAS and UAV started from the beginning of the 20^th century, and with the development of electronics, mechanics, material science, and computer science; UAS has rapidly developed over the last century, especially the latest thirty or forty years. With the rapid development of Artificial Intelligence over the first 20 years of the 21^st century ushered in a new stage of UAS and UAV development.
