Maple seed has long attracted many inventors for its unique capabilities to hover in the air. In the 1950s. researchers first tried to create drones that would repeat the form of the lionfish. But then their experiments have not yielded the desired results. The models proved unstable in the wind, they fell to the ground.
Experts from the University of Maryland have constructed his own version of the drone, which can be demanded to conduct intelligence operations, as well as in emergency situations. They created a radio-controlled model. It can easily take off from the ground, rotating in the air in a spiral. It can be reset to the aircraft or to start a hand, reports Physorg.
