Tim Kridel speaks to Li Zhiyuan, vice president of Ehang Egret and Raffaello D’Andrea, founder and CEO of Verity Studios Li Zhiyuan, EHang Egret vice president, explained how large a drone fleet can become, exploring the concept of the drone swarm.  TK: You completed a drone show featuring 1,374 drones, how much larger could drone light shows get over the next few years? 5,000 drones? 10,000 drones? And what kinds of displays could those massive swarms enable? Would more drones make it possible to create a light show that covers several miles/kilometres rather than a smaller area, such as a stadium? LZ: Technically we have the capacity of 5,000 or 10,000 or even more, because we have an intelligence command and control system to range all of our drones. But such a big show will be limited by lots of factors, like we have to apply for the certification of the airspace first, which will definitely be very large. We just finished a drone formation show in Haikou on the Lantern Festival, using 800 drones. In addition to continuously optimising the technology, we are also working on the design, switching 2D patterns to 3D patterns, making incredible visual effects. TK: How closely ca...
