First, let me clarify: I was confusing the Miura-Ori with the Magic Ball tessellation, though it's possible that either could work.Howel wrote:Thank you guys for reaching outBaltorigamist wrote:If I might ask, why do you need a working origami cannon?of course! this is a question that I have to answer. But I'm not good at origami!NeverCeaseToCrease wrote:And I'm as curious as Balto, why do you need a cannon, especially one that fires on its own?
the question is: "Folded paper structures such as the Miura-ori origami can be programmed to exhibit a wide range of elastic properties depending on their crease and defect patterns. Design and build an origami cannon to vertically launch a standard Ping-Pong ball using only a single uncut sheet of A4 paper (80g/m²)."
Can you help me? Or do you know anyone who can?Baltorigamist wrote: The Miura-Ori corrugation /might/ work for that, but you'd need to come up with some kind of a launch mechanism and probably wetfold it.
The technique I have in mind involves folding the corrugation on one side of the paper and leaving plain pleats on the other side. Then you could bend the corrugated part back on itself (kind of like a black hole shape) with the regular pleats outlining a cavity on the inside. You could lock the pleats together and place the ball in the middle, then pull the pleats down and release them to launch the ball.
(I know it's hard to picture, so maybe I can come up with an example to show you.)
