To prepare for their flight at Kitty Hawk, the Wright brothers studied the movements of pigeons to figure out how they stayed high up when they were heavier than air. Their success inspired scores of successors to improve on the airplane by studying various aspects of nature. One of Orville Wrights pupils caught and stuffed seagulls to examine their wingspan. Meanwhile, two French inventors examined spinning sycamore(梧桐) seeds in an effort to apply those same motions, reversed, to a helicopter.
Some examples are more obvious than others. The outside of the airplane designed by the Wright brothers looks like a minimalistic (简单抽象艺术) structure. On the other hand, Barney Connetts fish submarine (潜水艇) actually looks like a fish.
Some bio-inspired concepts have yet to be invented. In the 1960s, the US Army commissioned several university professors to conduct research on the motor skills animals in hope of applying those same abilities to tanks. Tanks that run like horses or jump like grasshoppers(蚂蚱)-sounds shocking, doesnt it? But imagine how life would change if we could achieve that.
