To acquire some perspective and information on the current flapping wing MAVs, it is useful to investigate the existing product that has been completed by a variety of research groups, companies and personal maker. Depending on distinct different size, flapping wing air vehicles (ornithopers) can be differentiated into two groups, MAVs and full-size ornithopters. The first group, as mentioned is the vehicles with dimensions less than 0.2m. The second group is relevant to large vehicles. The concerns of size limitations have intensively correlations with flapping mechanisms.
The flapping mechanism is the primary issue and technique in flapping MAVs because it is used to convert the rotary motioin into an oscillatory motion and hence makes a distinction between an airplane or helicopter. Currently, there are four classifications of mechanisms used in MAVs, double crank, double pushrod, single pushrod and side mounted crank. Some successful flapping wing mechanisms already exist. It was found that mechanisms were able to flapping at higher frequencies and dynamically flew [25-26].
McIntosh et al. [27] have been manufactured a mechanism which is able to flapping two rigid wings while also having the capability of changing the pitching angle. Both the pitching and flapping motions are created through the use of one actuator. The logic in this mechanism is imitated from many insects, what the wing is rotated at the top and bottom of each flap. The main plunging motions were…
