During the National Day holiday, the sky above Shenzhen was lit up by impressive drone(无人机) light shows. This"cyber fireworks" lit up the night, painting a lively picture of Shenzhen as a"City of Miracles, City of Innovation. City of Future". A total of 10197 DAMODA drones took to the sky at the same time, setting two Guinness World Records. So how does the drone light show work?
Before a drone light show begins, drones are usually put on the ground one by one and it would take a lot of time to prepare a show with more than ten thousand drones. To shorten the time, the DAMODA drone company thought of a solution. The company put groups of drones into big boxes with specific QR codes on it. By putting the boxes into correct places, thousands of drones can be ready in a short time and they can go back to their"homes" by scanning the OR codes.
In drone shows, each drone is programmed by a computer to follow its own flight direction, carefully avoiding the other drones. They communicate with neighbouring drones and use sensors(传感器) to keep a certain distance. The position and LED colours change throughout the performance to show different objects in the night sky.
Drone light shows are thought to be more environmentally friendly— and certainly cause less noise and light pollution— than fireworks shows, so lots of big events are turning to them instead of fireworks. Drones can also be reused again and again so they will probably be more popular in the future.
