summary	This paper illustrates a fabrication methodology through which the inherent form of large non-linear timber components was exploited in the Wood Chip Barn project by the students of Design + Make at the Architectural Association’s Hooke Park campus. Twenty distinct Y-shaped forks are employed with minimal machining in the construction of a structural truss for the building. Through this workflow, low-value branched sections of trees are transformed into complex and valuable building components using non-standard technologies. Computational techniques, including parametric algorithms and robotic fabrication methods, were used for execution of the project. The paper addresses the various challenges encountered while processing irregular material, as well as limitations of the robotic tools. Custom algorithms, codes, and post-processors were developed and integrated with existing software packages to compensate for drawbacks of industrial and parametric platforms. The project demonstrates and proves a new methodology for working with complex, large geometries which still results in a low cost, time- and quality-efficient process.

title	Concepts and Methodologies for Multiscale Modeling: A Mesh-Based Approach for Bi-Directional Information Flows
source	ACADIA // 2016: POSTHUMAN FRONTIERS: Data, Designers, and Cognitive Machines [Proceedings of the 36th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-77095-5] Ann Arbor 27-29 October, 2016, pp. 308-317

summary	This paper introduces concepts and methodologies for multiscale modeling in architecture, and demonstrates their application to support bi-directional information flows in the design of a panelized, thin skinned metal structure. Parameters linked to the incremental sheet forming fabrication process, rigidisation, panelization, and global structural performance are included in this information flow. The term multiscale refers to the decomposition of a design problem into distinct but interdependent models according to scales or frameworks, and to the techniques that support the transfer of information between these models. We describe information flows between the scales of structure, panel element, and material via two mesh-based approaches. The first approach demonstrates the use of adaptive meshing to efficiently and sequentially increase resolution to support structural analysis, panelization, local geometric formation, connectivity, and the calculation of forming strains and material thinning. A second approach shows how dynamically coupling adaptive meshing with a tree structure supports efficient refinement and coarsening of information. The multiscale modeling approaches are substantiated through the production of structures and prototypes.

title	High-performance Spatial Composite 3D Printing

summary	This project explores the advantages of employing continuum material topology optimization in a 3D non-standard lattice structure through fiber additive manufacturing processes (Figure 1). Additive manufacturing (AM) has gained rapid adoption in architecture, engineering, and construction (AEC). However, existing optimization techniques often overlook the mechanical anisotropy of AM processes, resulting in suboptimal structural properties, with a focus on layer-by-layer or planar processes. Materials, processes, and techniques considering anisotropy behavior (Kwon et al. 2018) could enhance structural performance (Xie 2022). Research on 3D printing materials with high anisotropy is limited (Eichenhofer et al. 2017), but it holds potential benefits (Liu et al. 2018). Spatial lattices, such as space frames, maximize structural efficiency by enhancing flexural rigidity and load-bearing capacity using minimal material (Woods et al. 2016). From a structural design perspective, specific non-standard lattice geometries offer great potential for reducing material usage, leading to lightweight load-bearing structures (Shelton 2017). The flexibility and freedom of shape inherent to AM offers the possibility to create aggregated continuous truss-like elements with custom topologies.

title	Protocol of Error: The design and construction of a bending-active gridshell from natural bamboo
source	Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 415-424

summary	This paper advocates alternative methods to overcome the impossibility of realising ‘perfect’ digital designs. It discusses Hong Kong’s 2015 ‘ZCB Bamboo Pavilion’ as a methodological case study for the design and construction of architecture from unprocessed natu- ral bamboo. The paper critically evaluates protocols set up to deal with errors resulting from precise digital design systems merging with inconsistent natural resources and onsite craftsmanship. The paper starts with the geometric and tectonic description of the project, illus- trating a complex and restrictive construction context. Bamboo’s unique growth pattern, structural build-up and suitability as a bending- active material are discussed and Cantonese bamboo scaffolding craftsmanship is addressed as a starting point for the project. The pa- per covers protocols, construction drawings and assembly methods developed to allow for the incorporation and of large building toler- ances and dimensional variation of bamboo. The final as-built 3d scanned structure is compared with the original digital model. The pa- per concludes by discussing the necessity of computational architec- tural design to proactively operate within a field of real-world inde- terminacy, to focus on the development of protocols that deal with imperfections, and to redirect design from the virtual world towards the latent opportunities of the physical.

title	Catenary Wooden Roof Structures: Precedent knowledge for future algorithmic design and construction optimisation
source	Dokonal, W, Hirschberg, U and Wurzer, G (eds.), Digital Design Reconsidered - Proceedings of the 41st Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2023) - Volume 1, Graz, 20-22 September 2023, pp. 611–620

summary	The timber industry is expanding, including construction wood product applications such as glue-laminated wood products (R. Sikkema et al., 2023). To boost further utilisation of engineered wood products in architecture, further development and optimisation of related tectonic systems is required. Integration of digital design technologies in this endeavour presents opportunities for a more performative and spatially diverse architecture production, even in construction contexts typified by limited means and/or resources. This paper reports on historic precedent case study research that informs an ongoing larger study focussing on novel algorithmic methods for the design and production of lightweight, large-span, catenary glulam roof structures. Given their structural operation in full tension, catenary-based roof structures substantially reduce material needs when compared with those relying on straight beams (Wong and Crolla, 2019). Yet, the manufacture of their non-standard geometries typically requires costly bespoke hardware setups, having resulted in recent projects trending away from the more spatially engaging geometric experiments of the second half of the 20th century. The study hypothesis that the evolutionary design optimisation of this tectonic system has the potential to re-open and expand its practically available design solution space. This paper covers the review of a range of built projects employing catenary glulam roof system, starting from seminal historic precedents like the Festival Hall for the Swiss National Exhibition EXPO 1964 (A. Lozeron, Swiss, 1964) and the Wilkhahn Pavilions (Frei Otto, Germany, 1987), to contemporary examples, including the Grandview Heights Aquatic Centre (HCMA Architecture + Design, Canada, 2016). It analysis their structural concept, geometric and spatial complexity, fabrication and assembly protocols, applied construction detailing solutions, and more, with as aim to identify methods, tools, techniques, and construction details that can be taken forward in future research aimed at minimising construction complexity. Findings from this precedent study form the basis for the evolutionary-algorithmic design and construction method development that is part of the larger study. By expanding the tectonic system’s practically applicable architecture design solution space and facilitating architects’ access to a low-tech producible, spatially versatile, lightweight, eco-friendly, wooden roof structure typology, this study contributes to environmentally sustainable building.

title	Parametrizing Indian Karnata-Dravida Temple Using Geometry
source	Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 409-420
summary	The Karnata-Dravida temple tradition flourished and evolved for 700 years. The evolution of the typology was demonstrated through the structure. However, as the Shastras or ancient texts proclaim, the underlying principles of geometry remain unchanged. Geometry and the unchanging principles of construction made the architects experiment with form, material and ornamentation. Geometry does not only mean shapes or two dimensional diagrams but it is a rule to amalgamate all the elements to form a dynamic form of a temple. The paper validates the use of geometry through an evolving sequence of Karnata-Dravida temples with the help of an analytical model created using the grasshopper software. The components of the model are based on the geometric rule (the basis for parametrizing) and parameters of the algorithm – plan forms, organizational compositions, vimana or superstructure composition – which result in a geometry. Even though building science is an old tradition, the use of computational procedures reveals the predictable nature of temples in the Dravidian clan and enables the analysis of existing temples, development of new possibilities or evolution of interpreted forms. Hence, enriching the existing understandings of previous scholarships in the field of temple architecture with an entirely new system of interpretation. In the age of technology where analytics plays a crucial role in almost all sectors, ancient temple architecture in India unfortunately falls behind when it comes to computational methods of restoration or reconstruction. This research questions the applicability of computational technology as a facilitator in preserving or reconstructing existing temples while maintaining its creative liberty.

title	Extruded Architectures: Grading weight-to-strength ratio of cement based materials through extrusion techniques
source	Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 745-754

summary	In recent years, a growing research agenda on the subject of additive manufacturing for architectural design has been established on the basis of jetting and extrusion technology. While jetting pro- vides enough flexibility to print multiple digital materials in a single run, extrusion has proven to be the most viable technique for large- scale and on-site manufacturing. Because major contributions of both research lines cannot be combined due to technological differences, special attention has been devoted towards the development of print- ing strategies that could approximate similar material flexibility of jet- ting by means of extrusion techniques. In this context, this paper pre- sents a computational design methodology for architectural components that enables grading weight-strength ratio of cement based materials through extrusion. Built upon the integration of mod- elling, analysis and fabrication, such methodology allows to optimize material distribution and geometric definition on the basis of physical and fabrication constraints. A case study is presented for describing the design processes of a circular column and the fabrication of a sec- tion it.

title	Adaptive Pneumatic Shell Structures - Feedback-driven robotic stiffening of inflated extensible membranes and further rigidification for architectural applications

summary	The paper presents the development of a design framework that aims to reduce the complexity of designing and fabricating free-form inflatables structures, which often results in the generation of very complex geometries. In previous research the form-finding potential of actuated and constrained inflatable membranes has already been investigated however without a focus on fabrication (Otto 1979). Consequently, in established design-to-fabrication approaches, complex geometry is typically post-rationalized into smaller parts and are finally fabricated through methods, which need to take into account cutting pattern strategies and material constraints. The design framework developed and presented in this paper aims to transform a complex design process (that always requires further post-rationalization) into a more integrated one that simultaneously unfolds in a physical and digital environment - hence the term cyber-physical (Menges 2015). At a full scale, a flexible material (extensible membrane, e.g. latex) is actuated through inflation and modulated through additive stiffening processes, before being completely rigidified with glass fibers and working as a thin-shell under compression.

title	Performative Agency of Materials: Matter agency of vernacular African pattern systems
source	Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 641-650
doi	https://doi.org/10.52842/conf.caadria.2016.641
summary	This paper investigates an agency of materials through a design methodology that follows Martin Heidegger’s process of “Entbergen” or “unconcealing” as a non-instrumentalist understanding of tools and materials. This investigation takes place through the de- sign of a children’s theatre in South Africa where material innovation for architectural components is needed. The research studies vernacu- lar African patterns and their inherent behaviour when transferred to materials. The transference of pattern systems to architectural proto- types is discussed alongside the discussion of their technical and ar- chitectural performance criteria. Following Heidegger’s theory of “Entbergen” (“unconcealing”) the paper will demonstrate how making in this methodology becomes an “unconcealing”, which includes both digital and analogue means, linking the four causalities - causa mate- rialis, causa formalis, causa finalis, and causa efficiens – through the agency of material within an integrated process between all four caus- es. Making becomes a process in which form is generated through in- terventions within fields of forces and currents of materials, taking cause and agency into account, and standing in opposition to methods that are defined by a premeditated notion of an ideal outcome.

title	In(flatable) Mod(uli): Air-buoyant, form-resistant, temporary structures
source	Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 405-414

summary	Conventional inflatable material systems offer a quick and reversible means of construction, however presenting limitations in terms of adaptability. Conventional, discrete, form-resistant structures feature stability through the complex organisation of discrete ele- ments, however featuring inertias in terms of flexibility and disecon- omies if applied to projects with a short lifespan. This paper discusses an alternative application of inflatable buoyant moduli to a discrete form-resistant structure in order to provide an adaptive installation for temporary events. Numerical and physical models are developed through a series of benchmarks, first, and a design project application eventually. The inherent predictability of this complex system is stud- ied in terms of constructability, costs, flexibility and spatial quality.

summary	While nonlinear concepts are widely applied in analysis and generative design in architecture, they have not yet convincingly translated into the material realm of fabrication and construction. As the gap between digital design model, shop drawing, and fabricated result continues to diminish, we seek to learn from fabrication models and natural systems that do not separate code, geometry, pattern, material compliance, communication, and form, but rather operate within dynamic loops of feedback, reciprocity, and generative fabrication. Three distinct, but connected problems: 1) Robotic ink drawing; 2) Robotic wine pouring and object detection; and 3) Dynamically Adjusted Extrusion; were addressed to develop a toolkit including software, custom digital design tools, and hardware for robotic fabrication and user interaction in cyber-physical contexts. Our primary aim is to simplify and consolidate the multiple platforms necessary to construct feedback networks for robotic fabrication into a central and intuitive programming environment for both the advanced to novice user. Our experimentation in prototyping feedback networks for use with robotics in design practice suggests that the application of this knowledge often follows a remarkably consistent profile. By exploiting these redundancies, we developed a support toolkit of data structures and routines that provide simple integrated software for the user-friendly programming of commonly used roles and functionalities in dynamic robotic fabrication, thus promoting a methodology of feedback-oriented design processes.

summary	The rapid emergence of computational design tools, advanced material systems and robotic fabrication within the disciplines of architecture and construction has granted designers immense freedom in form and assembly, while retaining pronounced control over output quality throughout the entirety of the design and fabrication process. Simultaneously, the complexity inherent within these tools and processes can lead to a loss of craft though the production of methodologies, forms and artifacts left with extremely recognizable residues from tooling processes utilized during their production. This paper investigates the fecund intersection of digital technologies and handcraft through core-less carbon fiber reinforced polymer (CFRP) winding as a means of creating a new typology of digital craft blurring the line between human and machine. Through the lens of an innovative wound CFRP shelter rolyPOLY completed during the winter of 2015, this paper will show the exigencies and affordances between the realms of digital and analog methodologies of CFRP winding on large-scale structures.

title	Printing Compound-Curved Sandwich Structures with Robotic Multi-Bias Additive Manufacturing
source	Proceedings of the 2023 DigitalFUTURES The 5st International Conference on Computational Design and Robotic Fabrication (CDRF 2023)
doi	https://doi.org/https://doi.org/10.1007/978-981-99-8405-3_44
summary	A research team at Florida International University Robotics and Digital Fabrication Lab has developed a novel method for 3d-printing curved open grid core sandwich structures using a thermoplastic extruder mounted on a robotic arm. This print-on-print additive manufacturing (AM) method relies on the 3d modeling software Rhinoceros and its parametric software plugin Grasshopper with Kuka-Parametric Robotic Control (Kuka-PRC) to convert NURBS surfaces into multi-bias additive manufacturing (MBAM) toolpaths. While several high-profile projects including the University of Stuttgart ICD/ITKE Research Pavilions 2014–15 and 2016–17, ETH-Digital Building Technologies project Levis Ergon Chair 2018, and 3D printed chair using Robotic Hybrid Manufacturing at Institute of Advanced Architecture of Catalonia (IAAC) 2019, have previously demonstrated the feasibility of 3d printing with either MBAM or sandwich structures, this method for printing Compound-Curved Sandwich Structures with Robotic MBAM combines these methods offering the possibility to significantly reduce the weight of spanning or cantilevered surfaces by incorporating the structural logic of open grid-core sandwiches with MBAM toolpath printing. Often built with fiber reinforced plastics (FRP), sandwich structures are a common solution for thin wall construction of compound curved surfaces that require a high strength-to-weight ratio with applications including aerospace, wind energy, marine, automotive, transportation infrastructure, architecture, furniture, and sports equipment manufacturing. Typical practices for producing sandwich structures are labor intensive, involving a multi-stage process including (1) the design and fabrication of a mould, (2) the application of a surface substrate such as FRP, (3) the manual application of a light-weight grid-core material, and (4) application of a second surface substrate to complete the sandwich. There are several shortcomings to this moulded manufacturing method that affect both the formal outcome and the manufacturing process: moulds are often costly and labor intensive to build, formal geometric freedom is limited by the minimum draft angles required for successful removal from the mould, and customization and refinement of product lines can be limited by the need for moulds. While the most common material for this construction method is FRP, our proof-of-concept experiments relied on low-cost thermoplastic using a specially configured pellet extruder. While the method proved feasible for small representative examples there remain significant challenges to the successful deployment of this manufacturing method at larger scales that can only be addressed with additional research. The digital workflow includes the following steps: (1) Create a 3D digital model of the base surface in Rhino, (2) Generate toolpaths for laminar printing in Grasshopper by converting surfaces into lists of oriented points, (3) Generate the structural grid-core using the same process, (4) Orient the robot to align in the direction of the substructure geometric planes, (5) Print the grid core using MBAM toolpaths, (6) Repeat step 1 and 2 for printing the outer surface with appropriate adjustments to the extruder orientation. During the design and printing process, we encountered several challenges including selecting geometry suitable for testing, extruder orientation, calibration of the hot end and extrusion/movement speeds, and deviation between the computer model and the physical object on the build platen. Physical models varied from their digital counterparts by several millimeters due to material deformation in the extrusion and cooling process. Real-time deviation verification studies will likely improve the workflow in future studies.

summary	This paper presents an integrated workflow for interactive design of shell structures, which couples structural and environmental analysis through a multi-agent systems (MAS) for design. The work lies at the intersection of architecture, engineering and computer science research, incorporating generative design with analytical techniques. A brief review on architectural shell structures and the structural logic of reciprocal frames is described. Through the morphological study of reciprocal frames locally we seek to inform the behavior of a MAS, which integrates form-finding techniques, with daylight factor analysis (DFA) and finite element analysis (FEA) on a global configuration. An experimental design is developed in order to explore the solution space of large span free form shells with varying topologies and boundary conditions, as well as identify the relationships between local design parameters of the reciprocal frames (i.e. number of elements, profile) and the analyses (i.e. stress distribution, solar radiation) for enabling the generation of different global design alternatives. The research improves upon design decision-making latency and certainty through harnessing geometric complexity and structural form finding for early stage design. Additionally, the research improves upon design outcomes by establishing a feedback loop between design generation, analysis and performance.

title	From Bones to Bricks: Design the 3D Printed Durotaxis Chair and La Burbuja Lamp

summary	Drawing inspiration from the variable density structures of bones and the self-supported cantilvers of corbelled brick arches, the Durotaxis Chair and the La Burbuja lamp explore a material-based design process by responding to the challenge of designing a 3D print, rather than 3D printing a design. As such, the fabrication method and materiality of 3D printing define the generative design constraints that inform the geometry of each. Both projects are seen as experiments in the design of 3D printed three-dimensional space packing structures that have been designed specifically for the machines by which they are manufactured. The geometry of each project has been carefully calibrated to capitalize on a selection of specific design opportunities enabled by the capabilities and constraints of additive manufacturing. The Durotaxis Chair is a half-scale prototype of a fully 3D printed multi-material rocking chair that is defined by a densely packed, variable density three-dimensional wire mesh that gradates in size, scale, density, color, and rigidity. Inspired by the variable density structure of bones, the design utilizes principal stress analysis, asymptotic stability, and ergonomics to drive the logics of the various gradient conditions. The La Burbuja Lamp is a full scale prototype for a zero-waste fully 3D printed pendant lamp. The geometric articulation of the project is defined by a cellular 3D space packing structure that is constrained to the angles of repose and back-spans required to produce un-supported 3D printing.

summary	This paper discusses the development of a bio-inspired compliant mechanism for architectural applications and explains the methodology of investigating movements found in nature. This includes the investigation of biological compliant mechanisms, abstraction, and technical applications using computational tools such as finite element analysis (FEA). To demonstrate the possibilities for building envelopes of complex geometries, procedures are presented to translate and alter the disclosed principles to be applicable to complex architectural geometries. The development of the kinetic façade shading device flectofold, based on the biological role-model Aldrovanda vesiculosa, is used to demonstrate the process. The following paper shows results of FEA simulations of kinetic curved-line folding mechanisms with pneumatic actuation and provides information about the relationship between varying geometric properties (e.g. curved-line fold radii) and multiple performance metrics, such as required actuation force and structural stability.

title	Computaç?o material: um estudo sobre a atualizaç?o geométrica de elementos vazados na arquitetura [Material computation: a study about the geometric updating of screenwalls in architecture]

summary	This paper deals with geometric update strategies of cobogós, aiming to expand its energy efficiency based on material computation, a design approach that seeks to achieve greater architectural performance through the investigation of material properties, comprising four aspects that structure the paper: materiality, material structure, material performance and materialisation. Analysis in ceramic, the most common material in the manufacturing of cobogós, showed voronoi microstructure geometry in the material. Incorporating this logic to the development of a new geometry of cobogó results a slight increase of its thermal performance comparing with commercial cobogós.

title	Prototyping Generative Architecture - Experiments on Multi-Agent Systems, Environmental Performance and 3D Printing
source	Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 145-154
summary	Computational design was developed to solve complex problems in architecture and to enable the establishment of systems with complex properties in a holistic manner. With the enhanced capabilities of computational design, there are possibilities to develop integrated approaches to adapt to multi-faceted design problems. Swarm-based multi-agent systems (MAS) are already used as generative bottom-up methods in various design operations, including form-finding and optimization. This study presents a systematic approach, in which multi-agent systems are informed by the environmental performance assessment data where the output is directly linked to the 3D printing process. The intent is to increase efficiency within the design and prototyping process by integrating performance and fabrication into the early stages of the design process. The proposed method has been applied as a case study to a diverse group of students and professionals. The results have proven that applying this systematic approach enabled the designers to achieve highly sophisticated, formal and organizational outputs, with enhanced spatial and geometric qualities.

title	Living on the Edge - Reinventing the amphibiotic habitat of the Mesopotamian Marshlands
source	Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 513-526
summary	The Mesopotamian Marshlands form one of the first landscapes where people started to transform and manipulate the natural environment in order to sustain human habitation. For thousands of years, people have transformed natural ecosystems into agricultural fields, residential clusters and other agglomerated environments to sustain long-term settlement. In this way, the development of human society has been intricately linked to the extraction, processing and consumption of natural resources. The Mesopotamian Marshlands, located in one of the hottest and most arid areas on the planet, formed a unique wetlands ecosystem, which apart from millions of people, sustained a very high number of wildlife and endemic species. Several historical, political, social and climatic changes, which densely occurred during the past century, completely destroyed the unique civilisation of the area, made all the wild flora and fauna disappear and forced hundreds of thousands of people to migrate. During the last decade, many efforts have been made to restore the marshlands. However, these efforts are lacking a comprehensive design strategy, coherent goals and deep understanding of the complex current geopolitical situation, making the restoration process an extremely difficult task. This work aims at providing strategies for recovering the Mesopotamian Marshlands, organising productive functions in order to sustain the local population and design a new inhabitation model, using advanced computational tools while taking into account the extreme climatic conditions and several unique cultural aspects. Part of the aim of this work is to advance the use of computation and explore the opportunities that digital tools afford in helping find solutions to complex design problems where various design variables need to be coordinated to satisfy the design goals. Today, advanced computation enables designers to use population consumption demands, ecological processes and environmental inputs as design parameters to develop more robust and resilient regional planning strategies. This work has the double aim of first, presenting a framework for re-inhabiting the Marshlands of Mesopotamia. Second, the work suggests a design methodology based on computer-aided design for developing and organising productive functions and patterns of human occupation in wetland environments.

title	Robotic Softness: An Adaptive Robotic Fabrication Process for Woven Structures

doi	https://doi.org/10.52842/conf.acadia.2016.154
summary	This paper investigates the potential of behavioral construction strategies for architectural production through the design and robotic fabrication of three-dimensional woven structures inspired by the behavioral fabrication logic used by the weaverbird during the construction of its nest. Initial research development led to the design of an adaptive robotic fabrication framework composed of an online agent-based system, a custom weaving end-effector and a coordinated sensing strategy utilizing 3D scanning.The outcome of the behavioral weaving process could not be predetermined a priori in a digital model, but rather emerged out of the negotiation among design intentions, fabrication constraints, performance criteria, material behaviors and specific site conditions. The key components of the system and their role in the fabrication process are presented both theoretically and technically, while the project serves as a case study of a robotic production method envisioned as a soft system: a flexible and adaptable framework in which the moment of design unfolds simultaneously with fabrication, informed by a constant flow of sensory information.
