An additional tracking controller, Neural-Swarm, helps the drones compensate for aerodynamic interactions, such as the downwash from a robot flying overhead. It’s already more reliable than a “commercial” controller that doesn’t account for aerodynamics, with far smaller tracking errors.
This could be useful for drone light shows, of course, but it could also help with more vital operations. Search and rescue drones could safely comb areas in packs, while self-driving cars could keep traffic jams and collisions to a minimum. It may take a while before there are implementations outside of the lab, but don’t be surprised if flocks of drones become relatively commonplace.
