World's smallest flying robots In the early 1930 's, Arthur Young, a brilliant young inventor, built and successfully demonstrated a viable, flyable helicopter model. In Oslo Peter Muren developed a totally silent and aerodynamically stable coaxial rotor flying robot.In Brussels Alexander Van de Rostyne developed a 6.9 grams helicopter with infrared 4 axis control. Very cute too .
