China: drones formed giant QR code to download game from mobile phone

At China, in the imposing city of Shanghai, a video game development company conducted a drone show which ended with a figure of a QR Code in the night sky, so people can scan. They were used 1,500 unmanned aircraft.

The event was to commemorate the video game’s first anniversary Princess Connect Re: Diving. The show started off with the drones making action figures related to the game, forming characters, for example. It all culminated with the giant QR code that viewers scanned with their mobile phones to access a connect with more information that allowed you to download the video game.

The event was hosted by China’s most popular video game, anime and manga platform called Bilibili, who programmed the drones to form the code. This is not the first time that the company has organized an event of this type to promote its products. Last year, the company placed a gigantic QR code on the building where it has its offices for the game’s launch.

Princess Connect Re: Diving it’s a role play for iOS and Android. It was launched 3 years ago in Japan, China, in April 2020, and globally in January 2021.

This is not the first time that the sky over Shanghai has had such a show with drones. The city has become the epicenter of this type of event. On March 29, an impressive spectacle of 3,281 drones that have become a new Guinness record.

With the demonstration of different synchronized tricks in the air, a new brand of cars was launched for the Asian market. On this occasion, the brand’s campaign record Genesis surpassed the precedent of Shenzhen Damoda intelligent control technology what did you use 3.051 drones at a trade show on September 20 last year. Previously, in 2018, the record was held in Pyeongchang in the Winter Olympics using 1.218 drones.

In the latter case, the devices drew the classic Olympic rings, among other figures, in the sky. This show was not performed live, at the time of the ceremony, but was recorded to ensure that there were no errors, and for the sky and weather conditions to be optimal.

The last show of the 3,281 drones set the record for Increase in the number of “drones in the air simultaneously”. The show, also held in the port of Shanghai, showed figures with perfect synchronization, and without no collision.

Thus, this type of visual spectacle begins to gain strength over the years, especially in competitions and exhibitions. To make these type of shows possible (are they replacing fireworks?), 3D animation programs are used to create the show, and each drone operates as if it were a pixel of the image that will be seen in the sky.

For synchronization, their location is not used relative to each other, but each flies individually controlled by a single computer, but programmed in a particular way. The role of each drone is designated before the start of flights, and depends on the state of charge and the GPS signal of each, its performance in the air.

The battery life of devices varies between models and brands, but is generally, for these cases, around 20 minutes (or a little longer) under ideal weather conditions (without cold, snow or extreme winds) .
