The ease of access to sophisticated computational technologies normally used for engineering purposes have thoroughly transformed the way architects can design and generate structures. In a first step of digitalization, traditional timber joining methods have been adapted for CNC-fabrication and manual assembly, enabling intricate joinery methods. The next step integrates the digital workflow to the extent of a fully automated assembly using robotic building processes. The potential of these processes calls for a rethinking of traditional connection geometry and requires the creation of specifically adapted joints to accommodate the constraints and precision of kinematic movement. This article gives an overview of recent developments in joining techniques for robotic assembly and investigates two prototypical timber structures, which were constructed in the framework of the NCCR Digital Fabrication at the ETH Zurich. The first structure consists of connections of multiple members with complex intersection geometries, which were joined through an ultrafast-curing resin. The second prototype consists of a double-story timber structure of more than 4,000 individual members with singular face to face connections with a maximum of two members, connected by carbon steel screws. The results are compared in terms of the relationship between computational form finding, joint geometry, connection system, robotic fabrication process, and structural stability. We discuss applications in the building industry, spatial potentials, structural challenges, and fabrication developments and conclude by showing the potential development in future research.
