"Immortal" drone when colliding with an obstacle will become flexible

I bought it, spent a lot, launched it and after a minute smashed the drone against the wall due to an accidental movement of my finger. The pain, suffering and despair so familiar to aspiring aircraft owners may be a thing of the past. The Swiss Polytechnic School of Lausanne (EPFL) has developed a drone design that does not break when struck, but rebuilds itself.

The researchers drew inspiration from fellow entomologists who described an interesting property of a wasp's wings. It remains rigid during flight, but as soon as the insect hits an obstacle, the wing becomes flexible and deforms, absorbing the impact energy. A similar principle is implemented in the car security system and it only remained to figure out how to return the damaged module to service without a visit to the repair service.

Swiss wizards replaced the rigid motor masts with elastic plates, and the motors themselves were attached to the base with magnets. When struck, the struts with the propellers literally detach from the body, the power supply is interrupted and the blades freeze. The structure is partially destroyed, but then the magnetic field pulls all the components into their rightful places. A second to restart the system and the invulnerable drone is back in the air.

The experimental drone survives a collision with a wall and a fall from a height of several meters with confidence. Plus, it's probably the simplest, cheapest and smallest anti-collision drone system on the market. An ideal device for those who are just starting to practice flying and are terribly worried about every failure. But can the technology be adapted to create large, useful drones, or is it intended to be toys for adults?
