Mount an umbrella to a drone and there you go, you have a flying umbrella. When [Alan Kwan] tried to do just that he found it wasn’t quite so simple. The result, once he’d worked it out though, is haunting. You get an uneasy feeling like you’re underwater watching jellyfish floating around you.
A grad student in MIT’s ACT (Art, Culture and Technology) program, [Alan’s] idea was to produce a synesthesia-like result in the viewer by having an inanimate object, an umbrella, appear as an animate object, a floating jellyfish. He first tried simply attaching the umbrella to an off-the-shelf drone. Since electronics occupy the center of the drone, the umbrella had to be mounted off-center. But he discovered that drones want most of their mass in the center and so that didn’t work. With the help of a classmate and input from peers and faculty he made a new drone with carbon fiber and metal parts that allowed him to mount the umbrella in the center. To further help with stability, the batteries were attached to the very bottom of the umbrella’s pole.
In addition to just making them fly, [Alan] also wanted the umbrella to gently undulate like a jellyfish, slowly opening and closing a little. He tried mounting servo motors inside the umbrella for the task. These turned out to be too heavy, but also unnecessary. Once flying outside at just the right propeller speed, the umbrellas undulated on their own. Watch them doing this in the video below accompanied by haunting music that makes you feel you’re watching a scene from Blade Runner.
Also interesting was that in some countries he couldn’t fly his jellyfish due to drone restrictions. Fortunately the FAA clarified their rules regarding drones just in time for him to be able to fly them in the U.S.
