Octet Truss Node Environment (from rhombic dodechedrons)

thingiverse

This is the local environment of a node in an octet-truss. The struts are made from rhombic dodecahedrons with faces pointing towards the direction of the octet-truss struts. # 3D Images: Sidenote: I've added some images for unaided 3D crossed-eye viewing. To attain autostereographic viewing superpower, follow these steps: Set your eyes' vergence at half the distance to the screen and simultaneously set your eyes' accommodation at the screen. It's essential to note that setting vergence and accommodation to different distances is unnatural and challenging to master. However, once you've achieved it, you'll possess this superpower forever. Keep training beyond initial success for easier results and increased capabilities. # Background This concept arose during an investigation into possible translatory and rotatory motions for self-replicating pick-and-place robots in a modular lattice that's part of the system. The idea is similar to the rails depicted in Fig. 28 from the paper "An Architecture for Universal Construction via Modular Robotic Components." However, instead of a planar square lattice, I'm opting for the simplest stiff 3D lattice: the octet-truss.
