I found that arms of small umbrellas have similar structure of bat’s arms/wings. Cutting the all the umbrella arms and keeping just two in specular position is possible to simulate the movement of a flying bat, and the umbrella fabric becomes the wings. The umbrella mechanics is sufficient for the movement required. The development of this project focus on applying motors which controls a linear motion, in order to automatize the movement.
My goal is to make just a prototype, but the final point which I’d like to achieve is to have an array of nine umbrella/bat, mounted in a modular structure.
Another possible development is simulate a jellyfish movement, based in the same structure.
