The dragonfly changes how to move four wings by way of flying. When accelerating, all the wings flapped at the same timing When gliding, don’t flutter and only changing the wing angle slightly to change the direction. When hovering, move the front and rear wings alternately. Cancel the reaction when the front wing was dropped with the rear wing. In the same way, cancal the reaction when the rear wing was dropped with the front wing. My research is to develop a robot that imitates dragonfly. And to make a mechanism to move the front wing and the rear wing alternately to hover.
