The translation of UAV in English is unmanned aerial vehicle, abbreviated as UAV. In addition, drone hi yo is a very vivid name, drone. The original meaning of this word is Xiongfeng, which is used to refer to the buzzing sound made by wasps, and the image of a small and flexible drone is also very vivid. In some movie clips, drone swarms are often regarded as bat swarms because of their fast flight status, small size, and dense formation.

In fact, although drones are often associated with high technology, in fact, drones in a broad sense were first born in the Kongming Lantern during the Three Kingdoms period in China. The earliest records of "unmanned aerial vehicles" in military affairs in human history can be traced back to the first Italian War of Independence in 1849. During the First World War in 1914, two British military officers first proposed the concept of drones. In 1917, the first automatic spiral stabilizer was born. This device can keep the aircraft in a balanced forward flight. The birth also brought the possibility for the development of drones in the future. In 1935, the "Queen Bee" drone came out, and the era of drones really began.

People say that war is the best fuel for science and technology, and the development of drones has also entered the fast lane with the outbreak of two world wars in the 20th century. However, in the 21st century today, drones have been widely used. It has been applied to all fields of human life. As early as 1983, Japan used drones for pesticide spraying, and this was the beginning of drones in the field of plant protection. In 1997, Australia developed a weather small drone for weather reconnaissance. In 2003, Americans put drones into use in forest fire fighting in emergency rescue. In 2012, China produced the world's first aerial photography integrated UAV, the Elf series. Since then, UAV aerial photography has officially entered the public.
