The RoboSwift can sweep its wings back and forth, changing the shape and the wing's surface area. The idea is to make the aircraft fly more efficiently and agilely than fixed-wing aircraft. The micro — airplane is powered by a special propeller that folds during gliding to minimize air drag. RoboSwift steers by sweeping back one wing more than the other. The difference in wing position allows RoboSwift to make very sharp turns. http://www.networkworld.com/community/node/17672"
