You could be excused for thinking that German robotics company Festo does nothing but put together fabulous prototype robots built to resemble kangaroos, jellyfish, and other living things. They do in fact actually make real industrial robots, but it’s hard not to marvel at their biomimetic experiments; Case in point, the feathered BionicSwift and absurd BionicMobileAssistant motile arm.
Festo already has a flying bird robot — I wrote about it almost 10 years ago. They even made a flying bat as a follow-up. But the BionicSwift is more impressive than both because, in an effort to more closely resemble its avian inspiration, it flies using artificial feathers.
“The individual lamellae [i.e. feathers] are made of an ultralight, flexible but very robust foam and lie on top of each other like shingles. Connected to a carbon quill, they are attached to the actual hand and arm wings as in the natural model,” Festo writes in its description of the robot.
The articulating lamellae allow the wing to work like a bird’s, forming a powerful scoop on the downstroke to push against the air, but separating on the upstroke to produce less resistance. Everything is controlled on-board, including the indoor positioning system that the bird was ostensibly built to demonstrate. Flocks of BionicSwifts can fly in close quarters and avoid each other using an ultra wideband setup.
