Take-off Mechanism in Beetle Flight Revealed by 3D Photogrammetric Reconstruction

Although, a tremendous effort has been put forth to mimic flapping flights, MAV-inspired flapping wing are unable to perform take off flight and it  seems to be a challenging topic for researchers. Taking into consideration of the currently driving system such as actuator, battery and the complexity of the link mechanism; it is quite difficult to fabricate MAV adopting both principles of jumping and flapping mechanism in flapping flight. Understanding the non-jumping take-off mechanism of flying animal is therefore necessary for the development of the flapping model which can take off. In this work, we used 3D high-speed video techniques to quantitatively analyze the wings and body of Allomyrina dichotomy during initiation periods of flight. We found that Allomyrina dichotomy take off without jumping. The detail of the flapping angle, angle attack of the wings and the roll, pitch, yaw angle of body were investigated to understand the mechanism of take-off in Allomyrina dichotomy.
