This testbed utilizes a projection-based Augmented Reality (AR) system to guide human operators through various manufacturing tasks. By projecting 1:1 scale digital instructions, marks, and alignment guidelines directly onto the physical workspace, the system facilitates easier material manipulation, assembly, and quality inspection. Integrated with an intuitive control interface, the platform enables workers to manage and dynamically reconfigure workflows on-site, while significantly reducing both ergonomic strain and material waste. Validated use cases include both the co-manipulation of composite sheets and the automated cutting of textiles, demonstrating the system’s adaptability across varied flexible manufacturing scenarios.
