Unmanned aerial vehicles (UAVs), also known as unmanned aerial vehicles (UAVs), are unmanned aircraft operated by radio remote control equipment and self-contained program control devices, or autonomously operated by onboard computers, either completely or intermittently.

Compared to manned aircraft, drones are often more suitable for tasks that are too "dull, dirty, or dangerous". Drones can be divided into military and civilian applications according to their respective fields of application. In terms of military use, drones are divided into reconnaissance aircraft and target drones. In terms of civilian use, the application of drones in the industry is a true necessity for drones; The application of drones in fields such as aerial photography, agriculture, crop protection, micro selfies, express delivery, disaster relief, wildlife observation, infectious disease monitoring, surveying, news reporting, power inspection, disaster relief, film and television shooting, and romantic manufacturing has greatly expanded the use of drones themselves. Developed countries are also actively expanding industry applications and developing drone technology.
