The paper deals with design of basic mechanism of wing movement in ornithopters and development of ornithopter. Flapping wing systems can fill the void left by traditional fixed and rotary wing drones for defence ,agriculture, civilian and research purpose mostly in university level projects . These systems are also known as ornithopters, seek to replicate bird flying . This rising interest has raised a series of problems like kinematics of machinery, design and development of mechanisms and the stability, guidance, control, and navigation of birds, aerodynamics and control to explore. In this work we have designed few wing working mechanisms and designed an ornithopter. The ornithopter has imitated the bird structure with wings developed using kinematics of machinery. Literature Survey:- A group of students at MIT university developed Smart Bird in early 2010s ,it is one of the first working examples of biologically inspired flapping bird like systems. Smart Bird developed by Festo in 2012 by a German company had a wingspan of around 2 meters and weighed just 500 grams. In MIT university Phoenix developed an ornithopter in 2009 which can carry load of 400 grams. In 2016 group from COEP, Pune built an ornithopter of 1.3 kg and tested it on a load cell beam setup.
