Thanks to radio-based indoor GPS with ultra-wideband technology (UWB) the BionicSwifts can fly safely and in a coordinated pattern in a defined airspace. To execute these flight manoeuvres as true to life as possible, the wings are modelled on the plumage of real birds. The agility of the artificial birds is not just due to their lightweight design and aerodynamic kinematics, but also to the use of function integration.
