Distributed Flight Array: Self-Assembling 'Drone Clouds' (VIDEO)

A 'cloud' of experimental new drones are able to form themselves into a larger, multi-rotor vehicle, and fly as one.

The Distributed Flight Array project by ETH Zurich has successfully tested the system, which uses 3D-printed hexagonal rotors with magnets on their sides.

The robots are able to detect each other, form into bigger craft and then fly 'as one', after computing how their aerodynamics have changed.
