Tensegrity structures

by Daniel Piker

Feb 15, 2011

In response to a recent comment on this video:

 

I'm posting the files here.

 

The same grasshopper definition should work with any collection of struts and cables you draw in Rhino.

 

This sort of thing does seem well suited to exploration in Kangaroo.

By making the cables elastic and giving them some pre-tension, the form can be allowed to relax into a position where all cables are in tension and it is stable, then it can be tested or fabricated with much stiffer cables.

 

btw - For inspiration I'd recommend Kenneth Snelson's website:

    Hi All, I know the group has been inactive for some time but i am developing a tensegrity structure that is cantilevered and was wondering if i could get some help in understanding how to set a series of fixed points on a vertical wall so i can run the physics on the cantilevered tensegrity structure?

    Thanks in advance

      Thanks Daniel.

      It was fun to play with tensegrity.
      I've created this spherical structure.

      The hardest part was creating the segments and tensors.
      Anybody knows about some plugins or scripts that can create this kind of spherical structures?

        Hi Daniel,

        I've just started working on a tensegrity definition with grasshopper/kangaroo.

        Thanks a lot for sharing your work.

        I must admit I'm not an expert user so apologies if some of my queries are a bit elementary.

        I downloaded your tensegrity demo however I get the following error:

        I am using Rhino 6 and have Kangaroo2 installed.

        How can I get these components?

        Any help would be greatly appreciated.
