“…In research, ideas are brought forward that deviate from static "digital chains". Behavioral and cyber-physical fabrication processes are defined by a set of adaptive rules and performative criteria (Brugnaro et al 2016;Helm et al 2017;Vercruysse et al 2018) and afford the ability to deal with uncertainties from the real world (Bruyninckx et al 2001;Jeffers 2016;Vasey et al 2014). In order to respond to the uncertainties, the fabrication system needs to be able to sense the as-built structure.…”

This paper presents and investigates a cyber-physical fabrication workflow, which can respond to the deviations between built- and designed form in real-time with vision augmentation. We apply this method for large scale structures built from natural bamboo poles. Raw bamboo poles obtain evolutionarily optimized fibrous layouts ideally suitable for lightweight and sustainable building construction. Nevertheless, their intrinsically imprecise geometries pose a challenge for reliable, automated construction processes. Despite recent digital advancements, building with bamboo poles is still a labor-intensive task and restricted to building typologies where accuracy is of minor importance. The integration of structural bamboo poles with other building layers is often limited by tolerance issues at the interfaces, especially for large scale structures where deviations accumulate incrementally. To address these challenges, an adaptive fabrication process is developed, in which existing deviations can be compensated by changing the geometry of subsequent joints to iteratively correct the pose of further elements. A vision-based sensing system is employed to three-dimensionally scan the bamboo elements before and during construction. Computer vision algorithms are used to process and interpret the sensory data. The updated conditions are streamed to the computational model which computes tailor-made bending stiff joint geometries that can then be directly fabricated on-the-fly. In this paper, we contextualize our research and investigate the performance domains of the proposed workflow through initial fabrication tests. Several application scenarios are further proposed for full scale vision-augmented bamboo construction systems.

“…Assuming that equipment and technical support is available, the amount of skill and time it takes to complete a materially based parametric design project, and then fabricate such a project at full-scale, does not fit into a studio course framework. One solution is to fit this learning experience into an intensive 4-12 weeks summer program or a multi-semester design build project -and this has been successfully demonstrated by a number of schools including the University of Stuttgart's ITECH program (Knippers et al 2018), and the Architectural Association's (AA) School of Architecture programs at Hooke Park (Prizeman 2005;Vercruysse, Mollica, and Devadass 2019) This approach, however, is primarily afforded within the framework of research-intensive post professional or doctoral research and therefore, leaving behind most other graduate or undergraduate students. While some degrees may offer specialized electives at the graduate or undergraduate level, time constrains greatly affect the students' capacity to experience the entire process and corresponding knowledge that comes with the design and construction of a working prototype at the building scale.…”

Material characteristic and fabrication methodologies informing design processes are a growing focus of research and pedagogy. Bio-mimetics, morphogenetics or material computation theories have mostly been used as integrative tools within their teaching methods. The authors of this paper have observed that these pedagogical models are most successful when they are coupled with a practical understanding of the tools and processes that are engaged in architectural production. Without this exchange, a growing disconnect emerges between the concept and the crafted artifact, leading to unfounded speculative projections rather than true applied understanding. As such, experimentation with tools and materials is essential for students to build knowledge on the constraints and possibilities that exist within a material or manufacturing technology. This learning process is not meant to be singular-applying to one material and one fabrication process-but rather a process that is learned and then can further be applied to other design problems. However, the research and development processes are usually too extensive for students to gain in-depth understanding of the methodology-a learning experience that is beyond the scope of a single architecture studio.
