The opening ceremony of any Olympics supplies pageantry at a worldwide scale, a celebration that, at its greatest, can create moments each bit as indelible because the video games themselves. In Pyeongchang, these watching the curtain-raiser at residence additionally witnessed a sight by no means seen earlier than: a record-setting 1,218 drones joined in a mechanical murmuration.
Drone exhibits just like the one on show on the Pyeongchang Video games have taken place earlier than; you might keep in mind the drone military that flanked Girl Gaga eventually 12 months’s Tremendous Bowl. However the burst of drones that stuffed the sky Friday evening—or early morning, relying on the place on this planet you watched—comprised 4 occasions as many fliers. With out hyperbole, there’s actually by no means been something prefer it.
Taking pictures Stars
As on the Tremendous Bowl, the Pyeongchang drone present comes compliments of Intel’s Taking pictures Star platform, which allows a legion of foot-long, eight ounce, plastic and foam quadcopters to fly in sync, swooping and swirling alongside an animator’s prescribed path.
“It is in essence know-how assembly artwork,” says Anil Nanduri, common supervisor of Intel’s drone group.
Additionally just like the Tremendous Bowl, the opening ceremony manufacturing you may see in your TV—or streaming system—was prerecorded. That is much less of a cheat than an insurance coverage coverage; tiny drones can solely deal with a lot abuse, and Pyeongchang is a chilly and windy metropolis.
Intel had deliberate to supply a reside model of the present for the Pyeongchang opening ceremony crowd, however needed to scrap it on the final minute. Nonetheless, the corporate plans to lean into reside exhibits all through the week, with a separate, 300-drone act anticipated to take off nightly for the medal ceremonies.
In earlier outings, the drone fleet has taken types like a waving American flag backing Gaga, or a twirling Christmas tree at Disney’s Starbright Holidays. The Pyeongchang manufacturing, as you would possibly count on, contains extra Olympic-themed animations, like a gyrating snowboarder and people iconic interlocking rings, all made doable by cautious coding, and the 4 billion shade combos enabled by onboard LEDs. (If you happen to missed the livestream, you may catch the entire thing on the NBC broadcast Friday evening.)
“In an effort to create an actual and lifelike model of the snowboarder with greater than 1,200 drones, our animation staff used a photograph of an actual snowboarder in motion to get the proper define and form within the sky,” says Natalie Cheung, Intel’s common supervisor of drone gentle exhibits.
Because it seems, convey 1,218 of these drones into concord would not current far more of a logistical problem than 300, due to how the Taking pictures Star platform works. After animators draw up the present utilizing Three-D design software program, every particular person drone will get assigned to behave as a type of aerial pixel, filling within the Three-D picture towards the evening sky.
And whereas extra drones does present a broader canvas, it maybe extra importantly affords a greater sense of depth.
“What you might have is an entire three-dimensional viewing area, so you may create a lot of fascinating results and transformations while you use that full functionality,” says Nanduri. “It is aways straightforward to fly extra drones for an animation and improve the attitude.”
With the animation in place, every drone operates independently, speaking with a central pc slightly than any of the drones round it. Simply earlier than takeoff, that pc additionally decides which drone performs what function, based mostly on the battery ranges and GPS power of every member of the fleet.
The drones can sometimes fly for a bit below 20 minutes, given the constraints of present lithium-ion battery know-how. In addition they typically launch at a little bit of a distance from the precise efficiency space, reducing showtime even tighter. However these handicaps apply equally to any drone present. Pyeongchang offered distinctive challenges all its personal.
Making It Work
Because the opening ceremonies reside snafu underscores, getting these drones able to flying in excessive circumstances includes some fine-tuning of a Taking pictures Star drone design that has in any other case remained pretty constant during the last two years.
“When you might have these multi-rotors, you are spinning these blades, it is all about how a lot elevate and thrust they’ll get,” says Nanduri. “You may have blades spinning in numerous instructions, and it is self-balancing. When you might have excessive winds, you mainly should counter that, particularly relying on the path of the wind. You want extra energy.”
Intel did not bodily change the form of the Taking pictures Star propellers. However after simulating numerous wind eventualities, the staff did tweak the design of the drones’ rotor cages for a tolerance increase to assist preserve the craft steady in windier circumstances.
As for the chilly, that impacts not a lot the drones themselves, however the batteries that cost them. Temperatures on web site will dip as little as 11 levels Fahrenheit in a single day, topping out at simply above freezing.

“Lithium-ion batteries and chilly do not actually go collectively,” says Nanduri. To that finish, the Intel staff examined Taking pictures Star efficiency in Finland to verify the drones nonetheless flew as anticipated—and for the size of time required for the Olympic exhibits. However extra importantly, they fine-tuned their storage techniques to restrict any potential harm deep freeze would possibly trigger. They’re going to even have climate monitoring and air site visitors stations on-site to make the ultimate name.
Finally, Intel has ambitions for its drone squad to graduate from performers to professionals. A fleet of totally programmable quadcopters has compelling implications for, say, search and rescue operations. Unlocking that potential would require a regulatory overhaul, although, one that does not appear probably within the fast time period.
For now, nevertheless, gentle present spectaculars look like a high quality means for Taking pictures Star drones to earn their preserve. Particularly now that they’ve had their second on the largest present on earth.
