title	Clamp links: A novel type of reciprocal frame connection
source	International Journal of Architectural Computing 2022, Vol. 20 - no. 2, pp. 378–399
summary	Reciprocal frames (RFs) are complex structural systems based on mutual support between elements. One of the main challenges for these structures is achieving geometrical complexity with ease for assembly. This paper describes the development of a new type of connection for RF that uses a single bolt to fix a whole fan. The method used was the Research Through Design, using algorithmic modelling and virtual and physical prototyping. After the exploration of different alternatives, the connection selected was structurally evaluated with a 3D solid finite element analysis (FEM) software and a 2D bar parametric model. Finally, a fullscale pavilion was built as a proof-of-concept. A total of 47 connections were fabricated using four 3D-printed templates combined with a hand router. The construction allowed us to draw conclusions on the connection design and the assembly method, and the process as a whole can contribute to the development of new structural links and production methods.

title	Kerf Guided Glulam - A novel way of creating curved glulam beams
doi	https://doi.org/10.52842/conf.ecaade.2022.1.085
source	Pak, B, Wurzer, G and Stouffs, R (eds.), Co-creating the Future: Inclusion in and through Design - Proceedings of the 40th Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2022) - Volume 1, Ghent, 13-16 September 2022, pp. 85–90
summary	This paper proposes a novel way of producing curved glulam timber elements where the formwork is integrated into a glulam beam. The method proposed accomplishes this by placing kerf cuts on a timber profile that gets bent and then encased in a wood laminate, forming the glulam beam. The kerf placement allows the beam to be asymmetrically curved. The optimal placement for the kerf cuts is found by feeding an initial goal curve to a form-finding definition that subdivides it and places markers where cuts need to be made while manipulating the beam geometry, ensuring that it matches the initial input curve. The benefit of this method is that it is not reliant on large-scale glulam setups but can be fabricated with basic wood workshop tools in conjunction with a 5-axis CNC mill. The simplified production process enables smaller manufacturers and designers to produce dynamic wooden structures while saving on materials and labour that would have gone into producing formwork that eventually gets discarded.

title	Felt and Fold - Design and manufacturing of customized nonwovens through robotic needle felting
doi	https://doi.org/10.52842/conf.ecaade.2022.1.195
source	Pak, B, Wurzer, G and Stouffs, R (eds.), Co-creating the Future: Inclusion in and through Design - Proceedings of the 40th Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2022) - Volume 1, Ghent, 13-16 September 2022, pp. 195–204
summary	This paper explores the potential of robotic needle felting for customized production of nonwoven textiles and their architectural applications. The possibility to program the robotic movement and locally control fiber density and distribution allows the design of nonwoven, heterogeneous materials with graded properties not by differentiating their chemical composition, but rather controlling their mechanical structure. We propose a parametric design and fabrication workflow relying on a 6-axis robotic arm. We describe design techniques for the generation of felted surfaces with varying material properties and their translation to instructions for robotic felting, as well as the physical fabrication setup. Within our research, the ability to locally differentiate material properties is further explored to create three-dimensional folding behaviors. We study how fiber densities affect their folding ability and geometry, examine qualities of resulting edges, analyze how they affect folding and finally design targeted folded structures by informing the felting pattern. While robotic felting has not yet found significant applications in architecture, the designs and prototypes demonstrate its potential in the architectural context, as it suggests new solutions for recyclable, circular building components or surfaces.

title	Augmented Bricks an Onsite AR Immersive Design to Fabrication Framework for Masonry Structures
doi	https://doi.org/https://doi.org/10.1007/978-981-19-8637-6_33
source	Proceedings of the 2022 DigitalFUTURES The 4st International Conference on Computational Design and Robotic Fabrication (CDRF 2022)
summary	The Augmented Bricks research project aims to develop an immersive design to fabrication framework for the assembly of masonry building components by incorporating robotic fabrication and augmented reality (AR) technologies. Our method incorporates two main phases: firstly, the design phase in which users’ gestures and interactions are being identified in AR for the immersive design and simulation process; secondly, an innovative robotic assembly phase in which users can control a robotic arm for assembly by interacting with the AR user interface (UI). Our framework is validated by the design and assembly of four brick-based columns. Our findings highlight that the proposed design to fabrication framework offers a novel, intuitive design inspiration and experience beyond the traditional design methods. It returns the task of assembling parametric structures with high-tech equipment back to the designers, allowing them to master and participate in the entire design to the fabrication process. The impact of this practice-based research will allow architects and designers to modify and construct their designs more simply and intuitively through the AR environment.

title	Reconfigurable Formwork System for Vision-Informed Conformal Robotic 3D Printing
doi	https://doi.org/10.52842/conf.ecaade.2023.1.387
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. 387–396
summary	Robotic additive manufacturing has garnered significant research and development interest due to its transformative potential in architecture, engineering, and construction as a cost-effective, material-efficient, and energy-saving fabrication method. However, despite its potential, conventional approaches heavily depend on meticulously optimized work environments, as robotic arms possess limited information regarding their immediate surroundings (Bechthold, 2010; Bechthold & King, 2013). Furthermore, such approaches are often restricted to planar build surfaces and slicing algorithms due to computational and physical practicality, which consequently limits the feasibility of robotic solutions in scenarios involving complex geometries and materials. Building on previous work (Çapunaman et al., 2022), this research investigates conformal 3D printing of clay using a 6 degrees-of-freedom robot arm and a vision-based sensing framework on parametrically reconfigurable tensile hyperbolic paraboloid (hypar) formwork. In this paper, we present the implementation details of the formwork system, share findings from preliminary testing of the proposed workflow, and demonstrate application feasibility through a design exercise that aims to fabricate unique components for a poly-hypar surface structure. The formwork system also offers parametric control over generating complex, non-planar tensile surfaces to be printed on. Within the scope of this workflow, the vision-based sensing framework is employed to generate a digital twin informing iterative tuning of the formwork geometry and conformal toolpath planning on scanned geometries. Additionally, we utilized the augmented fabrication framework to observe and analyze deformations in the printed clay body that occurs during air drying. The proposed workflow, in conjunction with the vision-based sensing framework and the reconfigurable formwork, aims to minimize time and material waste in custom formwork fabrication and printing support materials for complex geometric panels and shell structures.

title	Co-Robotic Assembly of Nonstandard Timber Structures
source	ACADIA 2022: Hybrids and Haecceities [Proceedings of the 42nd Annual Conference of the Association of Computer Aided Design in Architecture (ACADIA) ISBN 979-8-9860805-8-1]. University of Pennsylvania Stuart Weitzman School of Design. 27-29 October 2022. edited by M. Akbarzadeh, D. Aviv, H. Jamelle, and R. Stuart-Smith. 604-613.
summary	This paper presents a novel approach for the construction of nonstandard timber structures made from regionally sourced short dimensional lumber, which is enabled through human-robot collaborative assembly (HRCA). To address the research question, three main research objectives are identified and experimentally explored: 1) Characterization of a comprehensive construction process, which consists of off-site HRCA of bespoke timber sub-assemblies, 2) Development of a suitable constructive system for robotic assembly, making feasible the realization of articulated structures out of short timber elements, and 3) Incorporation of these techniques and their constraints into an integrative digital design and fabrication method and implementation of a continuous digital design-to-fabrication workflow.

title	In-Situ Robotic Fabrication of Spatial Glulam Structures
doi	https://doi.org/10.52842/conf.caadria.2022.2.041
source	Jeroen van Ameijde, Nicole Gardner, Kyung Hoon Hyun, Dan Luo, Urvi Sheth (eds.), POST-CARBON - Proceedings of the 27th CAADRIA Conference, Sydney, 9-15 April 2022, pp. 41-50
summary	While current approaches in timber construction stress the advantages of off-site prefabrication, glued laminated timber(glulam) structures is limited to the constraints of standardized, prefabricated mostly linear elements, which also lends itself only to building typologies that offer an increased level of standardization and regularity. The design freedom of timber structures is incomparable to that of reinforced concrete structures, which mostly gains from the in-situ fabrication process. An in-situ robotic timber fabrication platform allows the on-site construction of glulam structures with highly differentiated networks of beams composed of robotically assembled discrete linear elements. Based on the possibilities of such mobile robotic fabrication process, this paper explores novel architectural typologies of spatial glulam structures. The research is conducted from several aspects including joint tectonics, design method, and robotic fabrication process. A large-scale pavilion is designed and fabricated to verify the feasibility of the proposed system. This research could provide a novel mode of in-situ robotic timber fabrication and corresponding glulam structure system for timber construction.

title	Tolerance-Aware Design of Robotically Assembled Spatial Structures

University of Pennsylvania Stuart Weitzman School of Design. 27-29 October 2022. edited by M. Akbarzadeh, D. Aviv, H. Jamelle, and R. Stuart-Smith. 4-23.
summary	This paper presents a computational design method that integrates capabilities to manage material and fabrication tolerances occurring during the robotic assembly of spatial timber structures with tight-fit connections. This is achieved by building a data-base of tolerances measured during the robotic assembly process, which then allow for tolerance simulation as part of an assembly sequence planning method based on the Kruskal algorithm. Through a combination of optimization and linear regression techniques, the developed method enables designers to minimize deviations of their designs and diminish the risks of misfits during fabrication. In consequence, it allows for tolerance-aware designs.

title	A Collaborative Workflow to Automate the Design, Analysis, and Construction of Integrally-Attached Timber Plate Structures
doi	https://doi.org/10.52842/conf.caadria.2022.2.151
source	Jeroen van Ameijde, Nicole Gardner, Kyung Hoon Hyun, Dan Luo, Urvi Sheth (eds.), POST-CARBON - Proceedings of the 27th CAADRIA Conference, Sydney, 9-15 April 2022, pp. 151-160
summary	This paper introduces a computational framework that fosters collaboration between architects, engineers, and contractors by bridging the gap between architectural design, structural analysis, and digital construction. The present research is oriented toward the formulation of an automatic design-to-construction pipeline for Integrally-Attached Timber Plate Structures (IATPS). This construction system is based on assembling timber panels through the sole interlocking of wood-wood connections inspired by traditional Japanese joinery. Prior research focused on developing distinct computational workflows and dealt with the automation of 3D modelling, numerical simulation, fabrication, and assembly separately. In the current study, a single and interactive design tool is presented. Its versatility is demonstrated through two case studies, as well as the assembly of a physical prototype with a robotic arm. Results indicate that efficiency in terms of data flow and stakeholder synergy is considerably increased. The proposed approach contributes to the†Sustainable Development Goal (SDG) 11 by facilitating the collaborative design of sustainable timber structures. Besides, the research also contributes to SDG 9 as it paves the way for sustainable industrialisation of the timber construction sector through streamlined digital fabrication and robotic assembly processes. This reduces manufacturing time and associated costs while leveraging richer design possibilities.

Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 220-225.
summary	Previous research projects (Adel, Agustynowicz, and Wehrle 2021; Adel Ahmadian 2020; Craney and Adel 2020; Adel et al. 2018; Apolinarska et al. 2016; Helm et al. 2017; Willmann et al. 2015; Oesterle 2009) have explored the use of comprehensive digital design-to-fabrication workflows for the construction of nonstandard timber structures employing robotic assembly technologies. More recently, the Robotically Fabricated Structure (RFS), a bespoke outdoor timber pavilion, demonstrated the potential for highly articulated timber architecture using short timber elements and human-robot collaborative assembly (HRCA) (Adel 2022). In the developed HRCA process, a human operator and a human fabricator work alongside industrial robotic arms in a shared working environment, enabling collaborative fabrication approaches. Building upon this research, we present an exploration adapting HRCA to nail-laminated timber (NLT) fabrication, demonstrated through a case study exhibition (Figures 1 and 2).

summary	This paper discusses an ongoing interdisciplinary research project that develops a design and fabrication approach termed; tunable environments. This is an explorative approach, which enables updates from a digital parametric interface to be ‘pushed' into a 2D, 18 x 18 cm material sample, by modulating stimuli, so multiple properties can be updated/tuned at high resolutions. Our prototype explores how iterative updates can be achieved, which can be temporarily frozen in time. This opens up the idea of creating Parametric Matter/circular mate- rials, which could reduce waste that can be attributed to typical linear processes. Additionally, highly bespoke, ‘time-based’ structures could be achieved

title	Parametric Skin Design Method Based on Plane Crystallographic Group Operation Principle
doi	https://doi.org/https://doi.org/10.1007/978-981-19-8637-6_3
source	Proceedings of the 2022 DigitalFUTURES The 4st International Conference on Computational Design and Robotic Fabrication (CDRF 2022)
summary	Under the dual constraints of industrialization and digitalization, the building skin and structure are further integrated to form standardized units to meet the requirements of architectural performance, industrial prefabrication and “complexity” aesthetic characteristics. The complex and diverse forms of today's building skin hide profound mathematical logic relations and operation rules of form generation. Crystallographic group with regular symmetry and the operation principles reflected by it is one of the most important rules and methods of form and pattern processing in skin design. The study of the mural symbols in ancient Egypt, the murals in the Alhambra, the manuscripts of Escher and the window lattice in ancient Chinese architecture profoundly reflects the basic operation principle of crystal group in shaping the skin form of architecture. Abundant and diverse architectural skin forms can be formed through the operation of symmetry group on basic graphic units. On the basis of clarifying the basic principle of crystal group action, the operation matrix of crystallographic symmetry group can be transformed into parameterized operation steps through programming language for visual operation, and then the skin form with high complexity and leap dimension can be generated by geometric algorithm, and the design method of building skin generation based on crystallographic group is constructed. In the selection of operation form, combined with the calculation of building performance and structure, the construction skin can be used in practical engineering is generated. Based on crystallographic group operation, the unifications of building skin and the classification simplification of components can meet the requirements of modular and unifications design in the process of building industrialization, and meet the requirements of current building industrialization and digitization. It has great research significance and value in the aspects of design and construction efficiency and material economic cost.

summary	Inflatable structures made of flat film materials have an advantage of low cost, lightweight and rapid deployment, but the variation of their forms is relatively limited, and it is a challenge to produce pneumatic deformations. This paper proposes a designing and manufacturing process of inflatable structures which are made of flat film materials and are able to perform dynamic movements. The process includes steps in which a target 3D surface is produced through programmed 2D paths heat-sealed on flat films of different thickness, leading to a structure composed of air chambers. A parametric modelling procedure and associated principles are developed for the relationship between the forms of a flat-film-based inflatable structure and the heat sealing patterns on the film. A system of double-layer air chambers was designed to control the direction of bending movements. In addition, the form variation of a designed inflatable structure can be achieved by a parametric design process described in this paper.

summary	We present a synergetic combination of two previously separate process technologies to create novel lightweight structures. 3D textiles and 3D printing. We will outline the development of a novel material system that consisted of flexible and foldable 3D textiles that are combined with stiff, linear 3D printed materials. Our aim is to produce material-reduced lightweight elements for building applications with an extended functionality and recyclability. Within an ongoing research project (6dTEX), we explore a mono-material system, which uses the same base materials for both the filament for 3D printing and the yarn of the fabrication of the 3D textiles. Based on preliminary 3D printing tests on flat textiles key process parameters were identified. Expertise has been established for 3D printing on textiles as well as for using printable recycled polyester materials (PES textile and PETG filament. Lastly for 3D printing on non-combustible material (alkali-resistant (AR) glass textiles and for 3D concrete printing (3DCP). The described process- knowledge facilitates textile architectures with an extended vocabulary, ranging from flat to single curved and folded topologies. Whereas the foundations are laid in the research project on a meso scale, we also extended our explorations into an architectural macro scale. For this, we used a more speculative design-build studio that was based on a more loose combination of 3D textiles and 3D printed elements. Lastly, we will discuss, how this first architectural application beneficially informed the research project.

summary	This research explores implementing computation to enhance access to ocean pool and marine landscapes for the inclusion of people who are blind or have low vision (BLV). Constructing reliable representations, explanations and descriptions can support interactions with objects and participation in activities, particularly in these ocean environments. We discuss the adoption of a series of computational design strategies to leverage the impact of recent scanning technologies in information transfer. The paper introduces a background to touch access and universal design. It presents a case study of aerial photogrammetry for an ocean pool in NSW, Australia, and presents multi-scalar workflows and processes across computational design and advanced fabrication methods, including a) photogrammetry through drone-flight on a macro-scale and 3D-scanning to establish data-sets; b) parametric design and scale adaptations;†and c) 3D printing and robotic milling for touch access.

title	Hexagonal Responsive Facade Prototype in Responding Sunlight
doi	https://doi.org/https://doi.org/10.1007/978-981-19-8637-6_36
source	Proceedings of the 2022 DigitalFUTURES The 4st International Conference on Computational Design and Robotic Fabrication (CDRF 2022)
summary	This paper discusses an architectural responsive façade system using hexagonal parametric forms and kinetic mechanism which responds sunlight. Its purposes are to buffer excessive sun exposure that goes through interior space and maximize the covering area with an incremental rotational joint system. The study aims to explore responsive façade system as second skin for architectural building, focusing on design, mechanism, and fabrication processes. The prototype consists of three parts: the hexagonal modules where the membranes and its frames are compacted; a series of levers to synchronize the movement of opening the membranes from each module; and a structural framework to hold each module as united kinetic façade system. As a preliminary prototype, the system can potentially be applied to several types of existing buildings and easily installed in various sizes and configuration. This kinetic mechanism can decrease sun radiation up to 50% than unprotected window façade.
