1A2-A11 Effects on Lift Force of Feathering Motions of a Flapping Robot(Bio-Mimetics and Bio-Mechatronics (2))

Abstract

We have developed a flapping robot with active feathering wings by using a "scissors swing motor (SSM)". In the present study, we investigate how the feathering motion, which changes the angle of attack of the wing, affects the lift by means of motion capture experiment. Infrared reflective makers were placed on the wing frames, and their 3D-coordinates were tracked. The weight change of the robot was monitored simultaneously with a load cell, and we measured the lift force produced by flapping motion. The results show that deformation of wing surface during the flapping motion deteriorates the lift, and the feathering motion effectively suppresses the deformation of the wing.
