A novel double-differential four-bar based flapping mechanism to emulate insect/hummingbird wing kinematics for a flapping-wing micro air vehicle (MAV). This mechanism was developed by Dr. Moble Benedict, Pranay Seshadri and Prof. Inderjit Chopra at the University of Maryland College Park. The key advantage of this mechanism is that it actively emulates insect wing kinematics without depending on the wing flexibility and at the same time is simple enough to be used on a flying MAV unlike some of the other complex mechanisms.
