Among the world's wonders, Leonardo da Vinci marveled at how birds fly, mulling over possible mechanics in what became his Codex on the Flight of Birds. He hit upon some relevant physical properties such as inertia and fluidity, going 鈥渟traight to the heart of how birds fly, asking a series of very specific questions,鈥 Richard Prum, an ornithologist at Yale University, told 探花精选 in "." 鈥淚t鈥檚 fantastic, almost eerie, how much progress he made.鈥
Imagine his reaction if da Vinci saw SmartBird (featured in the video above), a manmade airplane based on the look and movement of a herring gull. Created by a team led by Markus Fischer, of the German technology company Festo, the agile avi-plane flaps its 6.5-foot wings just like a bird. Weighing in at less than a pound, it鈥檚 ultralight, which contributes to its energy efficiency through air: Its overall energy consumption at takeoff is about 25 Watts, and 60-80 Watts (that鈥檚 like an incandescent light bulb) in flight.
Okay, awesome. But, why IS it? In short, judging by Festo鈥檚 and a Fischer gave to a TED audience, it serves as an example of efficient automation based on ideas that researchers can apply elsewhere to solve bigger industrial problems. You鈥檝e probably heard of ; SmartBird seems to embody the concept from wing to flapping wing.
Below are videos of two more animal-inspired designs by Festo.
