A new movement from TurrisMotus!

Found a new movement when animating in kangaroo, not sure if it's valid though. But it could be a promising way for making a collapsible "roof" structure. Of course this only works with zero thickness lines for now and it was animated only as a spring model without gravity or any other forces. But It's just the beginning. It could also become a mayor product fault, when you open the TurrisMotus and it collapses in onto itself when stretched out too far.

Full cilinder Turris

Finally found a way to build the tower like a cilinder in Grasshopper first and then run it through Kangaroo is order to "relax" the springs to the length I want them to be.
The resulting structure is the one I wanted to build in the first place.

Next step will be making control points to get it moving.

Simulated model

Finally after learning the basics of Kangaroo, thanks for all those instruction video's, I got some working result. It is a spring model of the basic structure and is an approximation to the paper. However it only simulated elastic deformation and since it's not sheet moddeled does not respond to double sided bending. But I'm pleased with this first result so far. check out the video.

The start

Introduction into the project.
Turris Motus, Latin for tower with movement, is a project that started when I was trying to make the corrugated core of a sandwich panel. What I noticed was that it would bend in y-direction when you induced bending in x-direction, something I would later find out is called Poisson's ratio.
A few experiment later I build a tower with some control strings to animate the structure, you can see a video of this here: http://www.youtube.com/watch?v=1hzFRypYEpE

Currently I am investigating the properties and laws behind the movement of TurrisMotus in the course Stand-Up Architecture At the faculty of Architecture from the TU Delft.
