Abstract
This paper presents an integrated design tool for structures composed of engineered timber panels that are connected by traditional wood joints. Recent advances in computational architecture have permitted to automate the fabrication and assembly of such structures using Computer Numerical Control (CNC) machines and industrial robotic arms. While several large-scale demonstrators have been realized, most developed algorithms are closed-source or project-oriented. The lack of a general framework makes it difficult for architects, engineers and designers to effectively manipulate this innovative construction system. Therefore, this research aims at developing a holistic design tool targeting a wide range of architectural applications. Main achievements include: (1) a new data structure to deal with modular assemblies, (2) an analytical parametrization of the geometry of five timber joints, (3) a method to generate CNC toolpath while integrating fabrication constraints, and (4) a method to automatically compute robot trajectories for a given stack of timber plates.

Summary
Computer Numerical Control machines (CNC) and In dustrial Robotic Arms (IRA) allow for automating complex fabrication and assembly processes that would otherwise be too time-consuming for cost-effective applications. This opportunity led to the development of so-called Integrally Attached Timber Plate Structures (IATPS) [4]. IATPS combine modern engineered wood panels with traditional timber joints that are digitally fabricated Beyond their aesthetic appeal, these joints fulfill a functional role as they allow each construction element to be precisely positioned with each other. The main interest of IATPS lies in the fact that they allow a high degree of prefabrication Designing such structures is not straightforward as multiple constraints influence the shape of the con nections between the panels. This contribution aims at completing this framework by integrating fabrica tion and assembly constraints in the 3D modeling of the connections
