title	Robotic Fabrication of Non-Standard Material
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

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	Spatial Wire Cutting: Cooperative robotic cutting of non-ruled surface geometries for bespoke building components
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. 529-538

summary	The research project Spatial Wire Cutting (SWC) investi- gates a multi-robotic cutting technique that allows for an efficient production of geometrically complex architectural components. Being pursued by the group of Gramazio Kohler Research at ETH Zurich, this approach involves a spatially coordinated movement of two six- axis robotic arms that control the curvature of a hot-wire, which adopts itself against the resistance of the processed material (e.g. pol- ystyrene). In contrast to standard CNC hot-wire cutting processes, in which the cutting medium remains linear, it allows the automated fab- rication of non-ruled, doubly curved surfaces. This pursuit includes the development of a custom digital design and robotic control framework that combines computational simulation and manufactur- ing feedback information. Ultimately, SWC enables a considerably expanded design and fabrication space for complex architectural ge- ometries and their construction through automated robotic technology. This paper addresses the applied workflow and technology 1) such as computational design and simulation, robotic control and adaptive fabrication, 2) results of application within a two-week design and building workshop, and 3) will conclude with further steps of future research.

summary	Working with CNC routers and robots is widely used in architecture and fabrication. Our paper describes ways to use these tools more intuitively yet accurately and without a profound knowledge. We have developed a workshop format, in which even inexperienced participants are able to quickly start working with these tools by shaping the non-rigid material sand. Various production methods and tools are incorporated such as "manual", "gestural", "CNC" and "robotic" to create various 3D forms which are captured by methods like 3D scanning, vacuum forming or glueing.

summary	Due to climate change and the problematic amount of waste and CO2 emissions in the construction industry, non-human organisms and sustainable solutions are key motivators of the study. This paper focuses on developing a bioreceptive (Guillitte, 1995) composite suitable for additive manufacturing, composed to support growth of various organisms. It investigates key properties which have shown to be beneficial for promoting biological growth, such as water absorption, water permeability, humidity, and surface texture. The study evaluates the effect of two groups of clay-based waste additives, wooden sawdust (Arslan, et al., 2021) and sediment material sourced from local tunnel excavation in Prague. Simultaneously the need for intelligent reintegration and waste use is prevalent. Additive fabrication offers the ability to test a variety of composites and (re-)integrate them into the manufacturing processes. Current approach explores how to design artificial environments/skins for greenery and small life with the potential to improve both diversity and survivability while maintaining a better climate in its immediate surroundings. Bioreceptive design has the potential to improve the quality of the urban environment and bring new aesthetic influences into it (Cruz and Beckett 2016, p. 51-64).

summary	The CorkCrete Arch was an experimental prototype built in the scope of a research project concerning the use of robotic fabrication technologies for non-standard solutions in architecture. It combined 2 materials, cork and GRC into a self-supporting lightweight building system, designed to explore the integration of different robotic fabrication technologies in one constructive solution. This paper is focused in providing a detailed description and analysis of the robotic fabrication process used in the production of the GRC components. The presented solution integrated robotic milling and hot-wire cutting technologies with a stratified mold design strategy that allowed for overcoming the limitations of each and enabled a time and cost efficient production process.

title	Highly Informed Robotic 3D Printed Polygon Mesh: A Nobel Strategy of 3D Spatial Printing
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. 298-307

summary	Though robotic 3D printing technology is currently undergoing rapid development, most of the research and experiments are still based on a bottom up layering process. This paper addresses long term research into a robotic 3D printed polygon mesh whose struts are directly built up and joined together as rapidly generated physical wireframes. This paper presents a novel “multi-threaded” robotic extruder, as well as a technical strategy to create a “printable” polygon mesh that is collision-free during robotic operation. Compared to standard 3D printing, architectural applications demand much larger dimensions at human scale, geometrically lower resolution and faster production speed. Taking these features into consideration, 3D printed frameworks have huge potential in the building industry by combining robot arm technology together with FDM 3D printing technology. Currently, this methodology of rapid prototyping could potentially be applied on pre-fabricated building components, especially ones with uniform parabolic features. Owing to the mechanical features of the robot arm, the most crucial challenge of this research is the consistency of non-stop automated control. Here, an algorithm is employed not only to predict and solve problems, but also to optimize for a highly efficient construction process in coordination of the robotic 3D printing system. Since every stroke of the wireframe contains many parameters and calculations in order to reflect its native organization and structure, this robotic 3D printing process requires processing an intensive amount of data in the back stage.

title	Catenary Wooden Roof Structures: Precedent knowledge for future algorithmic design and construction optimisation

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	An environmental perspective on digital fabrication in architecture and construction
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. 797-806

summary	Digital fabrication processes and technologies are becom- ing an essential part of the modern product manufacturing. As the use of 3D printing grows, potential applications into large scale processes are emerging. The combined methods of computational design and robotic fabrication have demonstrated potential to expand architectur- al design. However, factors such as material use, energy demands, du- rability, GHG emissions and waste production must be recognized as the priorities over the entire life of any architectural project. Given the recent developments at architecture scale, this study aims to investi- gate the environmental consequences and opportunities of digital fab- rication in construction. This paper presents two case studies of classic building elements digitally fabricated. In each case study, the projects were assessed according to the Life Cycle Assessment (LCA) frame- work and compared with conventional construction with similar func- tion. The analysis highlighted the importance of material-efficient de- sign to achieve high environmental benefits in digitally fabricated architecture. The knowledge established in this research should be di- rected to the development of guidelines that help designers to make more sustainable choices in the implementation of digital fabrication in architecture and construction.

title	Reality is interface: Two motion capture case studies of human–machine collaboration in high-skill domains
source	International Journal of Architectural Computing vol. 14 - no. 4, 398-408
summary	This article explores hybrid digital/physical workflows in the building trades, a high-skill domain where human dexterity and craft can be augmented by the precision and repeatability of digital design and fabrication tools. In particular, the article highlights two projects where historic construction techniques were extended through live motion capture of human gesture, information-rich visualization projected in the space of fabrication and custom robotic tooling to generate free-form running moulds. The first case study explores decorative plastering techniques and an augmented workflow where designers and craftspeople can quickly explore patterns through freehand sketch, test ideas with shaded previews and seamlessly produce physical parts using robotic collaborators. The second case study reimagines a roman vaulting technique that used terracotta bottles as part of an interlocking masonry system. Motion capture is used to place building elements precisely in material arrays with real-time visual feedback guiding the hand-held placement of each bottle. These case studies serve to underscore the emerging importance of reality capture in the design and construction of the built environment. Increasingly, the algorithmic power of computational tools and the nuances of human skill can be combined in hybrid design and fabrication workflows.

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.

summary	Beaver dams are formed by two main processes. One is that beavers select proper woods for constructing. The other one is that streams aggregate those woods to be assembled. Using this approach to construction structure is suitable for natural environment. In this paper, we attempt to develop a construction process which is suitable for all-terrain construction robot in the future. This construction process is inspired by beavers' construction behavior in nature. Beavers select proper sticks to make the structure stable. We predict that particular properties of sticks contribute gravity-driven assembly of wood structure. Thus, we implement the system with machine learning to find proper properties of sticks to improve selection mechanism of construction process. During this construction process, 3D scanner on robotic arm scans and recognizes sticks on terrain, and then robot will select proper sticks and place them. After placement, the system will scan and record the results for learning mechanism.

summary	Each year, the United States discards 375 million tons of concrete construction debris to landfills (U.S. EPA 2016), but this is a new paradigm. Past civilizations cannibalized their constructions to produce new architectures (Hopkins 2005). This paper interrogates one cannibalistic methodology from the past known as cyclopean masonry in order to translate this valuable method into a contemporary digital procedure. The work contextualizes the techniques of this method and situates them into procedural recipes which can be applied in contemporary construction. A full-scale prototype is produced utilizing the described method; demolition debris is gathered, scanned, and processed through an algorithmic workflow. Each rubble unit is then minimally carved by a robotic arm and set to compose a new architecture from discarded rubble debris. The prototype merges ancient construction thinking with digital design and fabrication methodologies. It poses material cannibalism as a means of combating excessive construction waste generation.

summary	The paper addresses a specific method for the production of custom-made, differentiated moulds for the realization of a complex, doubly-curved wall element during an international three-week architectural programme, Architectural Association (AA) Summer DLAB. The research objectives focus on linking geometry, structure, and robotic fabrication within the material agency of concrete. Computational workflow comprises the integration of structural analysis tools and real-time form-finding methods in order to inform global geometry and structural performance simultaneously. The ability to exchange information between various simulation, modelling, analysis, and fabrication software in a seamless fashion is one of the key areas where the creation of complex form meets with the simplicity of exchanging information throughout various platforms. The paper links the notions of complexity and simplicity throughout the design and fabrication processes. The aim to create a complex geometrical configuration within the simplicity of a single material system, concrete, presents itself as an opportunity for further discussion and development.

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.

title	Design optimization and robotic fabrication of tensile mesh structures: The development and simulation of a custom-made end-effector tool
source	International Journal of Architectural Computing vol. 14 - no. 4, 333-348
summary	This article presents an ongoing research, aiming to introduce a fabrication procedure for the development of tensile mesh systems. The purpose of current methodology is to establish an integrated approach that combines digital form- finding and robotic manufacturing processes by extracting data and information derived through elastic material behavior for physical implementation. This aspires to extend the capacity of robotically driven mechanisms to the fabrication of complex tensile structures and, at the same time, to reduce the defects that might occur due to the deformation of the elastic material. In this article, emphasis is given to the development of a custom-made end-effector tool, which is responsible to add elastic threads and create connections in the form of nodes. Based on additive fabrication logic, this process suggests the development of physical prototypes through a design optimization and tool-path verification.

summary	Reviewing the current research trends in robotic fabrication around the world, the trajectory promises new opportunities for innovation in Architecture and the possible redefinition of the role of the Architect in the industry itself. New entrepreneurial, innovative start-ups are popping up everywhere challenging the traditional model of the architect. However, it also poses new questions and challenges in the education of the architect today. What are the appropriate pedagogical methods to instill enthusiasm for new technologies, materials, and craft? How do we avoid the pure application of pre-set tools, such as the use of the laser cutter has become, which in many schools around the world has caused problems rather than solving problems? How do we teach students to invent their tools especially in a society that doesn't have a strong background in the making? The primary focus of this paper is on how architectural CAAD/ CAM education through the use of robotic fabrication can enhance student's understanding, passion and knowledge of materiality, technology, and craftsmanship. The paper is based on the pedagogical set-up and method of an M. Arch I studio that was taught by the author in fall 2016 with the focus on robotic fabrication, materiality, traditional timber construction systems, tool design and digital and physical craftsmanship.

summary	The past years have seen significant developments in the area of robotic design interfaces. Building upon visual programming environments, these interfaces now allow the creative industry to de- fine even complex fabrication processes in an easy, accessible way, while providing instant, production-immanent feedback. However, while these software tools greatly speed up the programming of robot- ic arms, many processes are still inherently slow: Subtractive process- es need to remove a large amount of material with comparably small tools, while additive processes are limited by the speed of the extruder and the properties of the extruded material. In this research we present a new method for incrementally shaping transparent polymer materi- als with a robotic arm, without requiring heat or dies for deep- drawing, thus allowing us to rapidly fabricate individual panels within a minimum of time.

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.

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
doi	https://doi.org/10.52842/conf.acadia.2016.308
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.

summary	Brick construction has a strong tectonic tradition in architecture, being used both as a structural and as an expressive material. Despite several technological innovations at the composition and production level, its application still relies on talented craftsmanship, which has some natural human limitations and has becoming harder to find in the present days. To overcome this problem, robotic assembly technologies have been introduced in the field, opening new design and construction possibilities. In this context, this paper intends to examine their application but from a different perspective, by examining how they can be used to connect with the traditions in brick construction. To do so, it presents and analyses the work of Portuguese architect Raúl Hestnes Ferreira, and develops a computational design and robotic fabrication research on the topics of corner, column and dome bricks. The production of a column design at the 1:1 scale using an automated process serves to reflect on the relevance of new technologies to innovate in accordance to tradition.
