This paper presents a new type of joints derived from a historic wooden puzzles. A rule-based computational grammar for generating the joints is developed based on the relationship between the three-dimensional shape and its two-dimensional “net”. The rhombic polyhedra family, cube, rhombic dodecahedron, and rhombic triacontahedron are fully explored in the paper as they are the central part of the joints and is enclosed by all the elements around. This paper also presents lattices derived from these joints, and provide structure analysis to compare the structural performance of these lattices. The non-orthogonal lattices provide new way of looking at lattice structures and also provide new challenges for designing assembly techniques for both human, robots, and drones.

  • The Proceedings of IASS Annual Symposia include the articles presented at each symposium. They are grouped by thematic sessions. These limited-length conference papers are reviewed and selected by the Scientific or Technical Committee of each symposium, and generally only those actually presented orally at the conference are included. Although the metadata for the papers is available to the public, only members of the IASS can view the full papers, for which the author(s) hold the copyright. Further information about the projects or research should be sought from the author(s).
