Tensegrity Membrane Folding (Kangaroo2)

Hello all! I am trying to model a membrane tensegrity structure using Grasshopper.

I am designing a variation of a Jitterbug mechanism for an artist-in-residence program. The part I am struggling with is creating a folding actuator in between the modules. So far, I have managed to use Kangaroo2 to represent the membrane and the bars, but I am stuck on how to bring these together in a way that makes them fold(horizontally or vertically) when force is applied to the center, to orchestrate the Jitterbug movement.

I would be glad if someone could guide me in the right direction! I am attaching an image that shows the open and closed states of the whole structure, and some images that show the type of fold I want to achieve, as well as my current .gh file.

Thank you very much in advance!

Hi.

I worked a bit on your file, is this what you are looking for?

Hello! Thank you so much for looking into it!

Currently, it seems that the rods are fixed, and when force is applied, the mesh moves away from the fixed points. I am trying to get the rods to move together with the mesh, to get the folding motion. Do you have any insight on how I could get there? I tried to sketch the movement I am going for in blue, on a view capture of how it currently looks.

Thank you again!
