Researchers at Xerox Parc have designed a reconfigurable robotic system based on the rhombic dodecahedron. While no working models of this system have been created (that we know of) the possibility of what could be done with this system is immense. Self similar modules have the ability to rotate around each other based on prescribed rules.

This projects was used as a precedent for a spatial project based on the rhombic dodecahedron module by Robert Miles Kemp for his thesis project on Meta-Morphic Reconfigurable Robots.
