Researchers created a ladybug-like robot whose wing snap open in milliseconds, just like its insect inspiration.When a ladybug takes flight, its wings spring open within a tenth of a second—faster than a blink of an eye. And once unfurled, those wings remain open, allowing them to flap quickly without risk of folding or buckling.
“If you fold the tape measure…and then release it, it’s going to open up quickly,” Cho says. “It’s basically the same principle.” The researchers put one of the remote-controlled robots to the test by directing it to leap from a roof, whip its wings open in midair, and glide to the ground. They tossed the other robot off the second floor of a building; after gliding to earth, this robot refolded its wings and crawled along the ground. The team also found that the design could be adapted to make a robot with flapping wings.
