This demonstration presents craft-inspired digital fabrication that is enabled by a human-robot interaction modality, regeneration, as introduced in our SCF 2022 paper. Regeneration refers to executing a self-similar robotic action sequence at differing positions on the material based on real-time human interaction. The concept of regeneration is grounded in the crafting process, in which intricate material behaviours are incorporated into artefacts by way of repeated actions. Accordingly, our demonstration will show how regeneration allows exploring material behaviours as part of design process in digital fabrication. Our demo session includes: 1) an explanatory video showing recordings of interactive robotic clay carving by way of regeneration, 2) a small collection of robotically carved clay tiles, 3) a poster that graphically explains regeneration interaction modality and how it supports to explore material behaviour during digital fabrication.
