Popis: Despite modern timber construction being on the forefront of digital technology in construction, subtractive CNC—fabrication technologies are still predominantly used in the industry. An important break in the digital chain occurs when prefabricated small building parts have to be assembled manually into functional modules. This can result in a loss of digital information in the process. Therefore, a robotic setup for timber construction was specifically developed by the authors enabling large-scale spatial fabrication possibilities using a combination of subtractive external tools for cutting and drilling and additive robotic operations. Through automatization techniques and innovative feedback processes, the system can minimize material waste by reacting to different material sizes even during the construction process. In a case study, which was undertaken in the course of the Master of Advanced Studies program in Digital Fabrication at ETH Zurich, a complete digital workflow using additive robotic fabrication processes in timber construction was realized. We demonstrate the conception of the worldwide first double-story robotically assembled timber structure, explain its fabrication processes including an integrated envelope, and conclude by analyzing the robotic fabrication technologies in terms of their efficiency and structural and functional capabilities and limits.
