Swiss researchers at the École Polytechnique Fédérale de Lausanne, or EPFL, have made virtually crash-resistant drone. The highly flexible drone uses an unique body structure made of of elastic bands, visco-elastic foam and magnet to absorb and dissipate the force of an impact. See the video below (although it is admittedly a little bit of a let down!)
The drone is functional, but is still in an experimental state. But this kind of engineering awesomeness offers a lot of possibilities for the future of drone structure. The team here at Drone Dossier sees this as something the drone racing world will be quick to pick up on.
