What is the working principle of drones?

What is the working principle of drones? Especially some drones can also help agricultural names spray pesticides,

I know that drone spraying services can save at least 50% of pesticide usage and 90% of water consumption by spraying, which will greatly reduce resource costs.

How is it achieved?

Drones use a variety of technologies to help agriculture. On one side you have data collection using the onboard camera and other sensors like LiDAR which can create incredibly accurate maps which can help determine crop yields, soil degradation, flooding etc and on the other side you have delivery systems, like spraying or seed planting which use the GPS and mapping technologies.

The data collection can be done with regualar small UAV sytems but of course you'll need something a lot more substantial if you're spraying or planting seeds.

UAV systems mainly include aircraft body, flight control system, data link system, launch and recovery system, integrated circuit system, etc. The flight control system, also known as the flight management and control system, is equivalent to the "heart" part of the UAV system. It has an important impact on the stability of the UAV, the reliability of data transmission, accuracy, and real-time performance. Its flight performance plays a decisive role;

The data link system can ensure the accurate transmission of remote control commands, as well as the real-time and reliability of UAV receiving and sending information, so as to ensure the timely effectiveness of information feedback and the smooth and accurate completion of tasks. The launch and recovery system ensures that the UAV can fly smoothly to reach a safe altitude and speed, and fall back safely from the sky to the ground after completing the mission.

UAV is an unmanned aerial vehicle with its own power, radio remote control or autonomous flight, which can perform multiple tasks and can be used many times. To realize the autonomous flight of the UAV and successfully complete the designated tasks, its flight control, navigation and guidance are the most critical technologies.
