[EN VIDÉO] World record: 1,374 drones show off in China With more than 1,300 drones engaged in an aerial choreography, Ehang, a Chinese manufacturer, broke the record of the genre on May 1, 2018. Behind all these flight plans, a single computer defined the positions and movements, which had to be done with precision to be measured in centimeters.
Almost all drones operate with multiples rotors. This mode of flight requires a lot ofenergy, and noise prevents sound recording when used for filming. the drone of the Japanese company NTT Docomo offers an alternative, in the form of a small airship. No risk, therefore, of seeing it fall to the ground in the event of a breakdown as was the case. in China.
Propellers drones are usually exhibited, representing a danger for anything they might touch, like birds or humans. We will remember the photo of singer Enrique Iglesias, his hand bloodied after trying to catch a drone during a concert. With this new drone, this is no longer a problem. He is lifted by a balloonhelium and does not embed any rotor.

A perfectly silent drone
The device uses a fairly original mode of propulsion. On each side of the ball is a small module ultrasound which creates currents ofair thanks to vibrations, thus moving the device. Such drone will not be able to operate outdoors, but it has the advantage of being perfectly silent. Equipped with a camera, it can therefore film indoors, for example during events, in commercial buildings … without risk for the participants and without the characteristic drone roar.
The device is also equipped with LED, and in the absence of a rotor it should have excellent autonomy. The company plans to market its drone by March 2022, but has not yet released a price.
