On Wednesday, American scientists announced they had designed the first flying jellyfish in the world. This is the first flying machine capable of hovering and move in the air by flapping its wings in a movement that mimics the swimming jellyfish, ensure its inventors. It could become the drone of tomorrow.
For a long time, the jellyfish fascinates engineers by way of summary and efficient movement, the result of millions of years of evolution with an eminently simple technique: alternating two movements of the umbrella that propels the animal by leaps and bounds.
Inspired by nature and the aviation pioneers of the early twentieth century, the “flying jellyfish” developed by Americans is a miniature and ultralight aircraft since weighs only 2.1 grams. According to Leif Ristroph, who works in the laboratory of applied mathematics at the University of New York, “at the outset, we wanted to make an insectoid robot that would be an alternative to the helicopter (…). Finally, we ended up with something a little odd: the Medusa “
.
engineers have reproduced this method to steal their little robot with four small wings 8 cm long, shaped flower petal. A tiny motor connected to a crankshaft, opens and closes the wings at 20 beats per second. The robot remains in the air with great stability without the need constantly expending energy to fix his plate. Leif Ristroph provides that “if the jars, it stabilizes alone (…). To change direction, it is enough to beat one of the four wings faster than others. “
Carbon fiber for the structure, transparent to the stabilizer wings movie, all materials used in the manufacture of robot jellyfish are available in model aircraft shops.
