Emerging technologies have brought about radical changes in the construction sector, paving the way for the effective implementation of innovative and non-standard architectural projects. One sector that particularly benefits is the construction of non-conventional timber structural systems. The development of techniques for complex joint fabrication remains a central challenge, with robotic and Augmented Reality (AR) technologies playing a crucial role in creating accurate, efficient, and flexible geometries. This study presents a comparative analysis of the precision achieved in timber joint fabrication using robotic automation and AR-assisted methods. By assessing accuracy through 3D scanning, error elimination, and fabrication efficiency, the research highlights the advantages and limitations of each approach. Experimental findings show that robotic fabrication ensures high precision in joint cutting, while AR-based cutting and assembly guidance improves adaptability, workflow optimization, and real-time flexibility. The findings contribute to a deeper understanding of how emerging technologies and human intervention can enhance the precision, efficiency, and feasibility of complex timber structure fabrication.
