Individual vehicles self-assemble, coordinate, and take flight

We’ve all heard the expression: “The whole is greater than the sum of its parts.” Alone, these vehicles can drive about on the ground, but it is not until they assemble that they are able to fly.

 

The Distributed Flight Array is a flying platform consisting of multiple autonomous single propeller vehicles that are able to drive, dock with their peers, and fly in a coordinated fashion. Once in flight the array hovers for a few minutes, then falls back to the ground, only to repeat the cycle again.

Distributed Estimation and Control

The individual vehicles of the Distributed Flight Array have fixed propellers that can lift them into the air, but the resulting flight is erratic and uncontrolled. Joined together, however, these relatively simple modules evolve into a sophisticated multi-propeller system capable of coordinated flight. The task of keeping the array in level flight is distributed across the network of vehicles. Vehicles exchange information and combine this information with their own sensor measurements to determine how much thrust is needed for the array to take-off and maintain level flight. If the array’s leveled flight is disturbed, each vehicle individually determines the amount of thrust required to correct for the disturbance based on its position in the array and the array’s motion.
