Geometry

The building blocks are arranged hierarchically. Fabricated two-dimensional parts are first assembled into struts and nodes. Each node is assembled from four identical parts, each with four slots, which are used to rigidly connect to struts. The struts house most of the functionality of this building system and so can be built in a few different ways depending on their intended purpose.

These structures are built in planes and can be linked to assemble quasi-isotropic structures using struts to change orientation and vertical spacers which offset every two nodes:

Regular rigid structure can be fulfilled using struts composed of two identical two-dimensional parts. Flexural struts can be assembled either from a combination of two-dimensional laminate parts, or from folded laminate parts. Furthermore, actuated struts can be assembled from two special part-types: one made of high permeability material such as iron or steel which houses two magnets and forms an E-core, and the other which serves as a mandrel on which a coil is wound.
