title	An integrated robotically-driven workflow for the development of elastic tensile structures in various scales
source	Odysseas Kontovourkis (ed.), Sustainable Computational Workflows [6th eCAADe Regional International Workshop Proceedings / ISBN 9789491207143], Department of Architecture, University of Cyprus, Nicosia, Cyprus, 24-25 May 2018, pp. 111-120
keywords	This paper presents an ongoing work towards the development of an integrated robotically-driven workflow that can be used for the design, development and subsequent fabrication of small-to large-scale elastic tensile mesh structures. This approach involves digital form-finding and optimization, driven by robotic manufacturing principles and it aims to overcome the limitations of currently available tools, to work either in the design or the fabrication phase of the process. At the same time, it involves the fabrication of systems in several scales followed by respective analyses of results according to the specific type and diameter of the material used. Specifically, form-finding and optimization are responsible for controlling the pretension of the elastic threads, aiming to determine the final tensile mesh and to generate the additive robotic tool-path. In parallel, the type and diameter of the material involved, define the necessary changes of the end-effector tool, which is responsible to implement the process. Despite that design results can be in any scale, for study purposes an experimentation into a small-scale is conducted, to evaluate the suggested automated construction process in general and the end-effector mechanism in particular.

title	Onsite Robotic Fabrication for Flexible Workspaces - Towards Design and Robotic Fabrication of an Integrated Responsive Ceiling System for A Workspace Environment
source	T. Fukuda, W. Huang, P. Janssen, K. Crolla, S. Alhadidi (eds.), Learning, Adapting and Prototyping - Proceedings of the 23rd CAADRIA Conference - Volume 1, Tsinghua University, Beijing, China, 17-19 May 2018, pp. 59-68
doi	https://doi.org/10.52842/conf.caadria.2018.1.059
summary	Open, flexible workspaces were introduced decades ago, but architectural design approaches to ceiling systems have not changed substantially. This paper discusses the development of strategies and prototypes for a lightweight, integrated ceiling structure that is robotically woven. Through geometrically complex, fibre-reinforced building elements that are produced onsite, a new distribution system for data and light can be provided and support individual and multi-group collaborations in an contemporary open-plan office for maximum flexibility. The paper introduces applied design research with case studies that test robotic weaving on an architectural ceiling. The second part contextualises the presented work by linking it to workspace scenarios and an on-site robotic process with a resulting data distribution that is designed to produce degrees of freedom for high flexibility in use, allowing occupants to organise the workspace layout autonomously so that workflow constellations in different teams can be adequately expressed through space. The paper concludes with a discussion of a framework for robotic methods developed for the carbon-fibre overhead weaving processes, followed by conclusions and outlook towards future potentials.

title	Buoyant Ecologies Float Lab. Optimized upside-down benthos for sea level rise adaptation
source	ACADIA // 2018: Recalibration. On imprecisionand infidelity. [Proceedings of the 38th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-17729-7] Mexico City, Mexico 18-20 October, 2018, pp. 414-423
doi	https://doi.org/10.52842/conf.acadia.2018.414
summary	This paper describes the Buoyant Ecologies project, an ongoing research collaboration between architects, marine ecologists, and manufacturers focused on developing integrated architectural, ecological, and material responses to climate change and sea level rise. The research employs techniques of design computation and robotic fabrication to develop an approach to coastal resilience that is rooted in material performance as it relates to marine habitats. The project explores the design and production of highly performative fiber-reinforced polymer substrates that interact productively with the underwater ecosystem to promote multi-scalar habitats for invertebrate animals, encouraging ecological diversity and serving as wave-attenuating structures that mitigate coastal erosion. In this regard, the research leverages computational workflows of modeling, simulation, and fabrication to interface between human and nonhuman species in a way that benefits the broader ecosystem. The paper discusses an iterative prototyping process that has led to the design and construction of the Float Lab, a larger-scale prototype of a floating breakwater.

doi	https://doi.org/10.52842/conf.ecaade.2018.1.841
summary	This research investigates the design and prototyping of fabrication machines that utilize multi-dimensional printing techniques to sculpt an invisible medium- airflow, inspired by its unique materiality, philosophical value, sensorial aspects, and increasing considerations of atmosphere and climate in architectural research and design. A series of robotic thermal devices were developed to modulate animated geometry sequences through scripted movements, designated coordinates, and temperature fluctuations. This paper elaborates in depth multi-stage developments and experiments that integrate various systems, fabrication processes, optical experiments and computational analysis. It situates the experimental process of the medium-driven fabrication with possible applications in architectural design as envisioning alternative environmental systems utilizing thermal byproducts under aesthetic and experiential considerations.

title	Robosense 2.0. Robotic sensing and architectural ceramic fabrication
source	ACADIA // 2018: Recalibration. On imprecisionand infidelity. [Proceedings of the 38th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-17729-7] Mexico City, Mexico 18-20 October, 2018, pp. 276-285
doi	https://doi.org/10.52842/conf.acadia.2018.276
summary	Robosense 2.0: Robotic Sensing and Architectural Ceramic Fabrication demonstrates a generative design process based on collaboration between designers, robotic tools, advanced software, and nuanced material behavior. The project employs fabrication tools which are typically used in highly precise and predetermined applications, but uniquely thematizes the unpredictable aspects of these processes as applied to architectural component design. By integrating responsive sensing systems, this paper demonstrates real-time feedback loops which consider the spontaneous agency and intuition of the architect (or craftsperson) rather than the execution of static or predetermined designs. This paper includes new developments in robotics software for architectural design applications, ceramic-deposition 3D printing, sensing systems, materially-driven pattern design, and techniques with roots in the arts and crafts. Considering the increasing accessibility and advancement of 3D printing and robotic technologies, this project seeks to challenge the erasure of materiality: when mistakes or accidents caused by inconsistencies in natural material are avoided or intentionally hidden. Instead, the incorporation of material and user-input data yields designs which are imbued with more nuanced traces of making. This paper suggests the potential for architects and craftspeople to maintain a more direct and active relationship with the production of their designs.

title	Ceramic Morphologies. Precision and control in paste-based additive manufacturing
source	ACADIA // 2018: Recalibration. On imprecisionand infidelity. [Proceedings of the 38th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-17729-7] Mexico City, Mexico 18-20 October, 2018, pp. 350-357
doi	https://doi.org/10.52842/conf.acadia.2018.350
summary	Additive manufacturing techniques (AMT), commonly referred to as 3D printing, are emerging as a new area of study for the production of ceramic elements at the architectural scale. AMT may allow architectural designers to break from the established means of designing with ceramic elements – a process where designs are typically confined to a limited selection of building components produced by machine, die or fixture. In this paper, we report a method for the design and additive manufacture of customizable ceramic masonry elements via paste-based extrusion. A novel digital workflow allowed for precise control of part design, and generated manufacturing parameters such as toolpath geometry and machine code. 3D scans of a selection of elements provide an initial analysis of print fidelity. We discuss the current constraints of this process and identify several on-going research trajectories generated because of this research.

title	Integrated Solid Timber. A multi-requisite system for the computational design,fabrication, and construction of versatile building envelopes
source	ACADIA // 2018: Recalibration. On imprecisionand infidelity. [Proceedings of the 38th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-17729-7] Mexico City, Mexico 18-20 October, 2018, pp. 424-433
doi	https://doi.org/10.52842/conf.acadia.2018.424
summary	The paper presents the development of a building system made from solid timber that fulfils the requirements of modern building skins while expanding the design possibilities through innovation in computational design and digital fabrication. Multiple strategies are employed to develop a versatile construction system that generates structure, enclosure and insulation while enabling a broad design space for contemporary architectural expression. The basic construction unit augments the comparatively high insulation values of solid timber by cutting longitudinal slits into beams, generating air chambers that further inhibit thermal conductivity. These units are further enhanced through a joinery system that uses advanced parametric modeling and computerized control to augment traditional joinery techniques. Prototypes of the system are tested at a building component level with digital models and physical laboratory tests. It is further evaluated in a demonstrator building to test development and further refine design, fabrication and assembly methods. Results are integrated into proposals for new methods of implementation. The results of the research thus far demonstrate the validity of the strategy, and continuing research will improve its viability as a building system.

title	Lucid Foam - Multi-Axis Robotic Hot-Wire Cutting for Translucency
source	Odysseas Kontovourkis (ed.), Sustainable Computational Workflows [6th eCAADe Regional International Workshop Proceedings / ISBN 9789491207143], Department of Architecture, University of Cyprus, Nicosia, Cyprus, 24-25 May 2018, pp. 123-130
keywords	Hotwire cutting of Styrofoam or Polystyrene has been a popular tool for developing fast prototypes by the architectural community. The introduction of multi-axis industrial robots in the architectural curriculum, and the enhancement of the design to fabrication process by software bridging the gap, provided an alternative meaning to the traditional mostly representational process of hotwire cutting.This paper sets out to document and assess the procedural methodology and the results of a series of integrated design to fabrication experiments that took place in the Institut für Experimentelle Architektur-Hochbau. By channelling design intention towards a component assembly for a translucent effect, students were asked to utilise industrial robots to fabricate and prototype via hotwire cutting, designs that refer to architectural elements. These elements, mainly due to their scale and the commercial availability of bulk Styrofoam panels, can lead to functional or ornamental representations of discrete elements, which can be assembled together as part of a greater design.

title	Full Integration: Closing the Gap on Technology Readiness
source	ACADIA // 2018: Recalibration. On imprecisionand infidelity. [Proceedings of the 38th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-17729-7] Mexico City, Mexico 18-20 October, 2018, pp. 98-107
doi	https://doi.org/10.52842/conf.acadia.2018.098
summary	This paper discusses the authors’ experiences and lessons learned through designing and constructing small- and large-scale robotic prototypes and the fully integrated use of VR and AR for design. Also of focus here are the methodological tools utilized to implement this student-led research in an interdisciplinary educational environment, as well as the design explorations of Mars habitation systems. Through the systems engineering approach, students will generate ideas that may or may not make it to the final design development stage, but may potentially be valuable to future real exploration habitats and mission architectures. The final prototype allows an assessment of the focus parameters, which are the vessels’ transformation capacities and layout adaption. The design objective of this project is to examine strategies for commonality between an interplanetary vehicle (IPV) and a Mars surface habitat. The presented design proposals address this challenge to create a common habitation system in both habitats so that crew members will be familiar with the layout, function, and location throughout the expedition. The design tools operate at the intersection of architectural layout design, mechanics, and structural design, and use origami folding techniques and structural form-finding concepts to generate shell action rigidity. In addition, the project develops a strategy for mobility and transformation of the surface habitat prior to its transformed configuration. The value here lies in understanding lessons from this strategy for both the design process as well as efficiency and optimization in design as a model for terrestrial design.

title	Designing with Biomaterials for Responsive Architecture - A soft responsive "bio-structural" hydrogel skin
source	Kepczynska-Walczak, A, Bialkowski, S (eds.), Computing for a better tomorrow - Proceedings of the 36th eCAADe Conference - Volume 2, Lodz University of Technology, Lodz, Poland, 19-21 September 2018, pp. 285-292
doi	https://doi.org/10.52842/conf.ecaade.2018.2.285
summary	Synthetic biomaterials are not only widely explored in tissue engineering, but also present important opportunities in responsive architecture, especially soft structures and skins. In this paper we present how water-containing hydrogels can be adapted to digital fabrication techniques to design a soft responsive skin with integrated skeleton and surface. This research project details preliminary investigation into how tough hydrogels with different material properties can be designed and incorporated into laser-cutting and 3D printing methods typically used in architectural design. The outcome of this research produces an early prototype of thermally sensitive, tough hydrogel skin that responds to environmental stimuli such as temperature and moisture. Our work provides initial insights into how a soft responsive "bio-structural" architectural skin can be designed by integrating actuation, structure, and skins.

title	Smart Slab. Computational design and digital fabrication of a lightweight concrete slab
source	ACADIA // 2018: Recalibration. On imprecisionand infidelity. [Proceedings of the 38th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-17729-7] Mexico City, Mexico 18-20 October, 2018, pp. 434-443
doi	https://doi.org/10.52842/conf.acadia.2018.434
summary	This paper presents a computational design approach and novel digital fabrication method for an optimized lightweight concrete slab using a 3D-printed formwork. Smart Slab is the first concrete slab fabricated with a 3D-printed formwork. It is a lightweight concrete slab, displaying three-dimensional geometric differentiation on multiple scales. The optimization of slab systems can have a large impact on buildings: more compact slabs allow for more usable space within the same building volume, refined structural concepts allow for material reduction, and integrated prefabrication can reduce complexity on the construction site. Among the main challenges is that optimized slab geometries are difficult to fabricate in a conventional way because non-standard formworks are very costly. Novel digital fabrication methods such as additive manufacturing of concrete can provide a solution, but until now the material properties and the surface quality only allow for limited applications. The fabrication approach presented here therefore combines the geometric freedom of 3D binderjet printing of formworks with the structural performance of fiber reinforced concrete. Using 3D printing to fabricate sand formwork for concrete, enables the prefabrication of custom concrete slab elements with complex geometric features with great precision. In addition, space for building systems such as sprinklers and Lighting could be integrated in a compact way. The design of the slab is based on a holistic computational model which allows fast design optimization and adaptation, the integration of the planning of the building systems, and the coordination of the multiple fabrication processes involved with an export of all fabrication data. This paper describes the context, design drivers, and digital design process behind the Smart Slab, and then discusses the digital fabrication system used to produce it, focusing on the 3D-printed formwork. It shows that 3D printing is already an attractive alternative for custom formwork solutions, especially when strategically combined with other CNC fabrication methods. Note that smart slab is under construction and images of finished elements can be integrated within couple of weeks.

doi	https://doi.org/10.52842/conf.acadia.2018.444
summary	This paper documents the computational design methods, digital fabrication strategies, and generative design process for Lumen, winner of MoMA & MoMA PS1’s 2017 Young Architects Program. The project was installed in the courtyard at MoMA PS1 in Long Island City, New York, during the summer of 2017. Two lightweight 3D digitally knitted fabric canopy structures composed of responsive tubular and cellular components employ recycled textiles, photo-luminescent and solar active yarns that absorb and store UV energy, change color, and emit light. This environment offers spaces of respite, exchange, and engagement as a 150 x 75-foot misting system responds to visitors’ proximity, activating fabric stalactites that produce a refreshing micro-climate. Families of robotically prototyped and woven recycled spool chairs provide seating throughout the courtyard. The canopies are digitally fabricated with over 1,000,000 yards of high tech responsive yarn and are supported by three 40+ foot tensegrity towers and the surrounding matrix of courtyard walls. Material responses to sunlight as well as physical participation are integral parts of our exploratory approach to the 2017 YAP brief. The project is mathematically generated through form-finding simulations informed by the sun, site, materials, program, and the material morphology of knitted cellular components. Resisting a biomimetic approach, Lumen employs an analogic design process where complex material behavior and processes are integrated with personal engagement and diverse programs. The comprehensive installation was designed by Jenny Sabin Studio and fabricated by Shima Seiki WHOLEGARMENT, Jacobsson Carruthers, and Dazian with structural engineering by Arup and lighting by Focus Lighting.

Online and Global. 24-30 October 2020. edited by B. Slocum, V. Ago, S. Doyle, A. Marcus, M. Yablonina, and M. del Campo. 340-349.
doi	https://doi.org/10.52842/conf.acadia.2020.1.340
summary	This paper presents the design, control system, and elastic behavior of ELAbot: a robotic bending active textile hybrid (BATH) structure that can self-form and transform. In BATH structures, equilibrium emerges from interaction between tensile (form active) and elastically bent (bending active) elements (Ahlquist and Menges 2013; Lienhard et al. 2012). The integration of a BATH structure with a robotic actuation system that controls global deformations enables the structure to self-deploy and achieve multiple three-dimensional states. Continuous elastic material actuation is embedded within an adaptive cyber-physical network, creating a novel robotic architectural system capable of behaving autonomously. State-of-the-art BATH research demonstrates their structural efficiency, aesthetic qualities, and potential for use in innovative architectural structures (Suzuki and Knippers 2018). Due to the lack of appropriate motor-control strategies that exert dynamic loading deformations safely over time, research in this field has focused predominantly on static structures. Given the complexity of controlling the material behavior of nonlinear kinetic elastic systems at an architectural scale, this research focuses on the development of a cyber-physical design framework where physical elastic behavior is integrated into a computational design process, allowing the control of large deformations. This enables the system to respond to conditions that could be difficult to predict in advance and to adapt to multiple circumstances. Within this framework, control values are computed through continuous negotiation between exteroceptive and interoceptive information, and user/designer interaction.

title	Machine learning for architectural design: Practices and infrastructure
source	International Journal of Architectural Computing vol. 16 - no. 2, 123-143
summary	In this article, we propose that new architectural design practices might be based on machine learning approaches to better leverage data-rich environments and workflows. Through reference to recent architectural research, we describe how the application of machine learning can occur throughout the design and fabrication process, to develop varied relations between design, performance and learning. The impact of machine learning on architectural practices with performance-based design and fabrication is assessed in two cases by the authors. We then summarise what we perceive as current limits to a more widespread application and conclude by providing an outlook and direction for future research for machine learning in architectural design practice.

summary	Strained gridshells has been one of the most efficient structure system to cover large spans by lightweight construction. Nevertheless, gridshells structure has been seldom used due to the difficulties in gridshells form-finding and erection, as well as its limitation of morphological possibilities. In this regard, this paper aims to provide an integrated design and fabrication approach for extending the application of strained gridshells into the field of complex geometries. First, a form-finding method for complex gridshells design was put forward and tested taking Enneper surface as examples; secondly, the form-finding result was further developed into a gridshells system consisting of continuous laths, rotatable joints and rigid edge beams, which were optimized afterwards based on the structural simulation result with Finite Element Analysis. Third, the construction difficulties of this system were fully addressed in the robotic fabrication and erection process of a full scale prototype. This research tries to fully combine the structural characteristics of the strained gridshell with digital fabrication technologies to extend the application of strained gridshells into structures with more complex geometries.

title	Design-static analysis and environmental assessment investigation based on a kinetic formwork-driven by digital fabrication principles

keywords	This research focuses on design-static analysis and environmental assessment procedures that are based on the idea of a flexible kinetic formwork used as the automated mechanism for the production of bricks for porous wall structures. A key aspect of this investigation is the Life Cycle Assessment (LCA) analysis study that is applied in order to achieve, in parallel with the automated procedure, the sustainable potential of the products. For this purpose, the design and construction flexibility of the product is taken into account from the early design decision making stage by examining different sizes of bricks under fabrication including massive or porous ones in order to test their design and static performance, aiming to adapt their shape in multiple functional and environmental scenarios. In parallel, the LCA impact of the given design scenarios are taken into consideration, again from the early design phase, and include, among other objectives, material minimization, less environmental impact of building materials and less energy consumption based on the proposed digital fabrication technology. This is examined by comparing digital design and robotic automated results using three types of ecological materials.

summary	There are severe environmental and ecological issues once we evaluate the architecture industry with LCA (Life Cycle Assessment), such as emission of CO2 caused by necessary high temperature for producing cement and significant amounts of Construction Demolition Waste (CDW) in deteriorated and obsolete buildings. One of the ways to solve these problems is Bio-Material. CELLULOSE and CHITON is the 1st and 2nd abundant substance in nature (Duro-Royo, J.: Aguahoja_ProgrammableWater-based Biocomposites for Digital Design and Fabrication across Scales. MIT, pp. 1–3 (2019)), which means significantly potential for architectural dimension production. Meanwhile, renewability and biodegradability make it more conducive to the current problem of construction pollution. The purpose of this study is to explore Cellulose Based Biomaterial and bring it into architectural scale additive manufacture that engages with performance in the material development, with respect to time of solidification and control of shrinkage, as well as offering mechanical strength. At present, the experiments have proved the possibility of developing a cellulose-chitosan- based composite into 3D-Printing Construction Material (Sanandiya, N.D., Vijay, Y., Dimopoulou, M., Dritsas, S., Fernandez, J.G.: Large-scale additive manufacturing with bioinspired cellulosic materials. Sci. Rep. 8(1), 1–5 (2018)). Moreover, The research shows that the characteristics (Such as waterproof, bending, compression, tensile, transparency) of the composite can be enhanced by different additives (such as xanthan gum, paper fiber, flour), which means it can be customized into various architectural components based on Performance Directional Optimization. This solution has a positive effect on environmental impact reduction and is of great significance in putting the architectural construction industry into a more environment-friendly and smart state.
