Bones or Joints..Moving rigid bodies

I am trying to make a series of objects that are connected at the edges and hinged. Is there anything like a bones tool...or a method for connecting two or more objects, such that when I rotate or move one, the other moves with it, as a whole...I'm looking to work with rigid bodies...not deformable geometry.

Any help would be great.

Hi Aaron,

For Inverse Kinematics you could have a look at either Kangaroo (Plug-in for GH by Daniel Piker) see example here: http://www.grasshopper3d.com/forum/topics/inverse-kinematics?commen...

Or you could do this outside of GH in Rhino with the New Bongo Beta 2.0 which is available for testing for Rhino v4 users: http://bongo3d.ning.com/

Thinking about it further you could do it manually provided you reference the pivot points correctly in a clearly defined hierarchical structure then GH would have no problems simulating an arm for example. see definition below:
