Earthen fleas are herbivores that belong to the hyperdiversal group of approximately 9,900 species and
Although the mechanism by which fleasas if catapulting themselves, overcoming significant distances for its size, was discovered back in 1929, it has not yet been sufficiently studied.
Researchers in their work used microcomputer tomography and high-speed imaging for images of flea movements, and then created a 3D model of the insect during the jump from the obtained images.
This made it possible to establish the exact mechanics of the jump anddetermine the role of the structure in the legs of the insect, which scientists call the "elastic plate". The system responsible for jumping is located in the hind legs of the beetle and is relatively simple. It contains only three sclerotized parts and several muscles that allow it to achieve acceleration when jumping in 8,650 square meters. m / s, which is 865 times greater than the acceleration of gravity.
Ejection Jumping Ejection Mechanismthe flea is so effective and simple that it can find application in robotics, as well as in engineering and industrial installations, the researchers note. In their work, they propose the design of a bionic limb inspired by beetles.
Previously scientists have created a robot capable of stitching vessels up to 0.3 mm in diameter. The first tests of a device for supermicrosurgery in humans were successful.
