Research teams from University of Zurich and EPFL in Lausanne have developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is useful when searching for victims of natural disasters. Inspired by birds that fold their wings in mid-air to cross narrow passages, it can even hold and transport objects along the way.“Our solution is quite simple from a mechanical point of view, but it is very versatile and very autonomous, with onboard perception and control systems,” explains Davide Falanga, researcher at the University of Zurich. In comparison to other drones, this morphing drone can maneuver in tight spaces and guarantee a stable flight at all times. The scientists designed a quadrotor with four propellers that rotate independently, mounted on mobile arms that can fold around the main frame thanks to servo-motors. The ace in the hole is a control system that adapts in real time to any new position of the arms, adjusting the propellers’ thrust as the center of gravity shifts.
