Abstract
This paper describes effects of the wings for flapping-wing robots on thrust forces. A dragon-fly inspired robot with four wings driven by four-bar link mechanisms was developed. Four types of wings that have various sizes and shapes were prepared for the robot and the thrust forces generated by the wings were measured using a balance. The time-averaged thrust was calculated from the balance of moments. Experimental results show that 20% decrease in wing size causes 40% decrease in thrust force, if the wings have the same shape. Thrust of the wings that have similar shape to dragonfly's wings is 1.2 times larger than that of rectangular wings.
