🤯🤯🤯 Recent plane crashes are being linked to bird strikes .... Meanwhile the birds are flashing lights!😲

3 commercials Jers crashed for the first time in history since 9/11. The math on that is ODD to say the least.

Not even that bird would cause the landing gear malfunction.

Did you know- On the shores of Lake Geneva in Switzerland, École Polytechnique Fédérale de Lausanne is home to many roboticists. It’s also home to many birds, which spend the majority of their time doing bird things. With a few exceptions, those bird things aren’t actually flying: Flying is a lot of work, and many birds have figured out that they can instead just walk around on the ground, where all the food tends to be, and not tire themselves out by having to get airborne over and over again. “Whenever I encountered crows on the EPFL campus, I would observe how they walked, hopped over or jumped on obstacles, and jumped for take-offs,” says Won Dong Shin, a doctoral student at EPFL’s Laboratory of Intelligent Systems. “What I consistently observed was that they always jumped to initiate flight, even in situations where they could have used only their wings.” Shin is first author on a paper published today in Nature that explores both why birds jump to take off, and how that can be beneficially applied to fixed-wing drones, which otherwise need things like runways or catapults to get themselves off the ground. Shin’s RAVEN (Robotic Avian-inspired Vehicle for multiple ENvironments) drone, with its bird-inspired legs, can do jumping takeoffs just like crows do, and can use those same legs to get around on the ground pretty well, too. Back in 2019, we wrote about a South African startup called Passerine which had a similar idea, albeit more focused on using legs to launch fixed-wing cargo drones into the air. This is an appealing capability for drones, because it means that you can take advantage of the range and endurance that you get with a fixed wing without having to resort to inefficient tricks like stapling a bunch of extra propellers to yourself to get off the ground. “The concept of incorporating jumping take-off into a fixed-wing vehicle is the common idea shared by both RAVEN and Passerine,” says Shin. “The key difference lies in their focus: Passerine concentrated on a mechanism solely for jumping, while RAVEN focused on multifunctional legs.” Bio-inspired Design for Drones Multifunctional legs bring RAVEN much closer to birds, and although these mechanical legs are not nearly as complex and capable as actual bird legs, adopting some key principles of biological design (like the ability to store and release energy in tendon-like springs along with some flexible toes) allows RAVEN to get around in a very bird-like way. Despite its name, RAVEN is approximately the size of a crow, with a wingspan of 100 centimeters and a body length of 50 cm. It can walk a meter in just under four seconds, hop over 12 cm gaps, and jump into the top of a 26 cm obstacle. For the jumping takeoff, RAVEN’s legs propel the drone to a starting altitude of nearly half a meter, with a forward velocity of 2.2 m/s.
