Development of Mini-Sized-Robot Based on Flight Mechanics of Dragonfly

Abstract

This report describes the development of mini-sized robot based on the flight mechanics of dragonfly. At first, the motion analyses of flapping and feathering motion of dragonfly's wing are carried out from the image data recorded by the ultra-high speed video camera under the free flight conditions. Applying the results obtained to the dynamic analysis of wing motion based on the flight mechanics, the thrust and lift forces of fore and hind wings are estimated. The predicted results by this theoretical model are reasonable and it may be applicable to artificial-wing design.
