In order to develop Micro Air Vehicles (MAV) for an explorer in disaster area, mechanical flapper based on insects' flight was developed. Aerodynamic forces and flapping motions were measured and compared to that of insects. The experimental results showed the flapping amplitude and feathering angle of the mechanical flapper were almost the same as that of real insects. The aerodynamic forces depended on the phase difference of forewing and hind wings. The maximum aerodynamic force can be obtained at the phase difference between forewing and hindwing is almost 0 degree. Moreover, the coefficient of energy becomes the minimum at this phase difference. The developed mechanical flapper generates aerodynamic lifting force which is enough to lift real insects.
