There are different types and uses of drones, such as reconnaissance, surveillance, traffic control, firefighting, agriculture, and entertainment. When a drone is in use, it may sometimes collide with some objects, causing damage to the drone's propellers. Therefore, anti-collision nets are installed on the propellers of drones to protect the propellers. When an emergency occurs again, the propellers will not be hit, thereby avoiding damage to the power unit, causing the drone to lose balance, and preventing the drone from being unable to land safely.
