Recent advancements in architectural robotics allow to explore the coupling of manual craft with digital tools. However, current methods remain limited in addressing high-skill, custom tasks involving material uncertainty. In this context, the paper presents three capacities that stand at the core of performing autonomous robotic craft. These include: documenting the movements and gestures of local stone craftsmen; augmenting the robotic system with a custom end effector and a sensor toolkit; and enhancing the fabrication process through a protocol that translates the documented data to an autonomous process. The three capacities aid in preserving local crafts, expanding robotic tools with new capabilities, and enabling architectural fabrication with a wider range of materials.
