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	Adaptive [skins]: Responsive building skin systems based on tensegrity principles
source	FUTURE TRADITIONS [1st eCAADe Regional International Workshop Proceedings / ISBN 978-989-8527-03-5], University of Porto, Faculty of Architecture (Portugal), 4-5 April 2013, pp. 155-170
summary	The project investigates responsive building skin systems that adapt to the dynamic environmental conditions to regulate the internal conditions in a habitable space over different periods of time by exhibiting a state of motion and dynamism. Heat and Light are the primary parameters for regulation, leading to energy efficiency and dynamic spatial effects. Passive and active skins using shape memory alloys and pneumatic actuators are developed through investigations of smart systems that integrate smart materials and smart geometries. The precedents in this domain have rarely dealt with individually controlled multiple parameters of heat and light in a single system, which is attempted in this project. Owing to the complexity of the multi-parametric system, genetic algorithms are developed for system optimization and calibrated with physical prototypes at varied scales. The developed systems are tested against two distinct climatic models- New Delhi and Barcelona, and evaluated for performance, based on heat and light, which are quantified as solar gain and illuminance as principles, and daylight factor for evaluation purpose. The use of genetic algorithms makes the problem solving faster and accurate. New tool-sets are developed in the process by combining various digital tools, to create a real-time feedback and memory loop system.

title	Responsive Materiality for Morphing Architectural Skins
doi	https://doi.org/10.52842/conf.acadia.2013.243
source	ACADIA 13: Adaptive Architecture [Proceedings of the 33rd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-926724-22-5] Cambridge 24-26 October, 2013), pp. 243-252
summary	This paper presents the design of a novel material system with sensing, form-changing and luminous capacities for responsive and kinetic architecture. This aim is explored and evaluated through an experimental design investigation in the form of an architectural skin. Through experimentation with alternative materials and a rigorous process of designing the responsive material systems,a new architectural skin, namely Blanket, emerged from this research. The newly developed responsive material system is an amalgamation of silicone rubbers and glowing pigments, molded and fabricated in a prescribed way—embedded with shape memory alloys on a tensegrity skeletal structure to achieve the desired morphing properties and absorb solar energy to glow in the dark.Thus, the design investigation explores the potential of the use of form-changing materials with capacitance sensing, energy absorbing and illumination capabilities for a morphing architectural skin that is capable of responding to proximity and lighting stimuli. This lightweight, flexible and elastic architectural morphing skin is designed to minimize the use of discrete mechanical components. It moves towards an integrated “synthetic” morphing architecture that can sense and respond to environmental and occupancy conditions.

title	Design Constraint Systems - A Generative Approach to Architecture
source	International Journal of Architectural Computing vol. 11 - no. 1, 37-63
summary	Generative Architectural Design permits the automatic (or semiautomatic) generation of architectural objects for a wide range of applications, from archaeological research and reconstruction to digital sketching. In this paper the authors introduce design constraint systems (DCS), their approach to the generation of architectural design with the help of a simple example: The development of the necessary formalisms to generate a family of architectural designs, i.e. simple houses and pagodas. After explaining the formal system the authors introduce an approach for the generation of complex form based on the application of transformations and distortions.Architecture is bound by the constraints of physical reality: Gravitation and the properties of the used materials define the limits in which architectural design is possible. With the recent development of new materials and construction methods however, the ways in which form and physics go together get more complicated. As a result, the shapes of architecture gain more liberty, and more and more complex shapes and structures become possible.While these advances allow for new ways of architectural expression, they also make the design process much more challenging. For this reason new tools are necessary for making this complexity manageable for the architect and enable her to play and experiment with the new possibilities of complex shapes and structures. Design constraint systems can be used as tool for experimentation with complex form. Therefore, the authors dedicate the final part of this paper to a concise delineation of an approach for the generation of complex and irregular shapes and structures. While the examples used are simple, they give an idea of the generality of design constraint systems: By using a two-component approach to the generation of designs (the first component describes the abstract structure of the modelled objects while the second component interprets the structure and generates the actual geometric forms) and allowing the user to adjust both components freely, it can be adapted to all kind of different architectural styles, from historical to contemporary architecture.

title	Shipping Complexity: Parametric Design for Remote Communities
source	Global Design and Local Materialization[Proceedings of the 15th International Conference on Computer Aided Architectural Design Futures / ISBN 978-3-642-38973-3] Shanghai, China, July 3-5, 2013, pp. 167-175.
summary	This paper presents a system for design and construction of a parametrically designed, structural shell for remote communities. It explains how, through the use of various digital software platforms, a single-layer, structural shell is designed and optimized and subsequently how a series of customized joints can be output for direct digital fabrication. As the customization is focused primary in the joints of the structure, standard dimension, locally sourced structural members can be used. By embedding assembly information onto the physical joints, the system has the capacity to simplify the construction of complex shell structures by workers with basic construction skills. Flat-packed joints can be shipped to remote sites without heavy structural members thereby reducing transportation costs and the overall embodied energy. By lowering cost and simplifying construction of large span structures, the project is intended to extend the benefits of digitally driven design to rural, remote or under-privileged communities.

summary	The development of new shapes in architecture has deeply influenced the current perception of the built environment. The analysis of the processes behind this evolution is, therefore, of great interest. At least two well known factors, influencing this development, may be pointed out: the great improvement of digital tools and the tendency toward building distinctiveness.In particular, the innovation of digital tools such as parametric modeling is resulting in an overall diffusion of complex shapes, and the phenomenon is also evident in a clear expressionistic search for architectural singularity, that some might consider as a negative effect of globalization trends.Though, if we can consider as a positive result the fact that parameterization allows a deeper control over design factors in terms of reference to cultural, historical and physical context, at the same time such control possibilities are sometimes so stark to be even auto-referential, stepping over site-specific parameterization, to create unusual shapes just for the sake of complexity.The ever-growing diffusion of generative design processes is in fact going to transform niche procedures, frequently limited to temporary decontextualized structures, into an architectural complexification as an end in itself.The hypothesis of this paper is to demonstrate that site-specific parametrization can be considered as a tool able to translate intentions into shape; it is necessary, for this aim, the widening of the meaning of the word singularity.

summary	This is the first volume of the conference proceedings of the 31st eCAADe conference, held from 18-20 September 2013 at the Faculty of Architecture of Delft University of Technology in Delft, the Netherlands. Both volumes together contain 150 papers that were submitted and accepted to this conference.The theme of the 31st eCAADe conference is the role of computation in the consideration of performance in planning and design. Since long, a building no longer simply serves to shelter human activity from the natural environment. It must not just defy natural forces, carry its own weight, its occupants and their possessions, it should also functionally facilitate its occupants’ activities, be aesthetically pleasing, be economical in building and maintenance costs, provide temperature, humidity, lighting and acoustical comfort, be sustainable with respect to material, energy and other resources, and so forth. Considering all these performance aspects in building design is far from straightforward and their integration into the design process further increases complexity, interdisciplinarity and the need for computational support.One of the roles of computation in planning and design is the measurement and prediction of the performances of buildings and cities, where performance denotes the ability of buildings and cities to meet various technical and non-technical requirements (physical as well as psychological) placed upon them by owners, users and society at large.This first volume contains 75 papers grouped under eleven subthemes that vary from Design Decision-Making over Spatial Performance and Space Syntax to Digital Fabrication.

title	Breaking the Mold: Variable Vacuum Forming
doi	https://doi.org/10.52842/conf.acadia.2013.269
source	ACADIA 13: Adaptive Architecture [Proceedings of the 33rd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-926724-22-5] Cambridge 24-26 October, 2013), pp. 269-278
summary	Our research explores the growth of surface complexity through careful attention to program and performance criteria. As this complexity emerges, however, we are repeatedly confronted with the realization that its cost compromises any of its performance gains. While the aggregation of repeatable units with variation from one unit to the next is achievable at a low cost through subtractive fabrication technologies (CNC milling, laser cutting, waterjet cutting), it is more difficult to achieve through casting or forming technologies (concrete casting, injection molding, vacuum forming). This is because formwork is not adaptable. Once you produce a mold, typically at a high cost, that mold makes one component only. If you want variation, a new mold must be produced for each new component. With the projects Hexwall and VarVac Wall we put forward a simple question: can an intelligent, adaptable vacuum-forming mold be developed that allows for difference from one component to another without the necessity for multiple molds? The research positions our design efforts strategically at the front end of the fabrication process. Our goal is to develop a malleable tool that allows for endless variation in a fabrication process where variation is typically impractical.

title	Alloplastic Architecture: The Design of an Interactive Tensegrity Structure
doi	https://doi.org/10.52842/conf.acadia.2013.129

summary	This paper attempts to document the crucial questions addressed and analyze the decisions made in the design of an interactive structure. One of the main contributions of this paper is to explore how a physical environment can change its shape to accommodate various spatial performances based on the movement of the user’s body. The central focus is on the relationship between materials, form and interactive systems of control.Alloplastic Architecture is a project involving an adaptive tensegrity structure that responds to human movement. The intention is to establish a scenario whereby a dancer can dance with the structure such that it reacts to her presence without any physical contact. Thus, three issues within the design process need to be addressed: what kind of structure might be most appropriate for form transformation (structure), how best to make it adaptive (adaptation) and how to control the movement of the structure (control). Lessons learnt from this project, in terms of its structural adaptability, language of soft form transformation and the technique of controlling the interaction will provide new possibilities for enriching human-environment interactions.

summary	Media façades grant infinitely many faces to a building and can change the architectural meaning of what a façade is. They can also help to transform the face of the building into an over-size communication device for public (Borras, 2010). Contemporary media façades mostly rely on the content of their screens, and only a small number of them physicality of the screen itself. Precedent building façades that incorporate moving componentsareunable to function as displays. In this paper we present a media façade design, titled“Tran[s]quillity”, in which we fuse reconfigurable building com-ponents with display technologies to achieve a unique design. As well as fulfilling the function of a regular media wall -as a crisp screen- we imagine Tran[s]quillity as a transformable kinetic sculpture that can act as a screen of physical depth to introduce greater functionality and interactivity.

summary	The term “robot” was born from a play written almost a century ago. Today robotic fabrication has become an emerging topic in architectural research. As architects work with these technologies, they are challenged with writing a different kind of play: here robots are the actors and the physical materialization of a design is their performance. However current Computer Aided Design (CAD) packages do not provide native robot programming functionalities which architects require to plan and orchestrate these fabrication process. To address this limitation, a Python library for robot programming is written. It is referenced by a toolkit of custom components developed to extend a graphical programming environment commonly used for architectural design. The empirical development of these software tools takes place in the context of a design studio investigating the subject of the high rise. The tools are tested in a workflow that involves the digital design and scaled robotic fabrication of high-rise housing. This paper discusses the considerations underlying the toolkit’s design, the outcomes of its use in the studio, and its impact on the creative design process.

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	Pedagogic Approach in the Age of Parametric Architecture: Experimental method for teaching architectural design studio to 3rd year level students
source	Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 211-226
summary	In this era, Architectural Design Practice is faced with a paradigm shift in its conventional approaches towards computational methods. In this regard, it is considered a pedagogic challenge to boost up knowledge and skills of architectural students’ towards an advanced approach of architectural design that emphasizes the potentials and complexity of computational environments and parametric tools for design problem solving. For introducing the concept of Parametric Oriented Design Methods to 3rd year level architectural students, an experimental pedagogic course was designed in the scholastic year of 2012-2013 at German Jordanian University GJU (School of Architecture and Built Environment SABE) to approach this concept. In the preparation phase, the experimental course was designed to incorporate structured instructing and training method to be consecutively performed within experimental lab environment to target predetermined learning outcomes and goals. The involved students were intentionally classified into three levels of previous involvement associated with the related software operating skills and computational design exposure. In the implementation phase, the predetermined instructing and training procedures were performed in the controlled environment according to the planned tasks and time intervals. Preceded tactics were prepared to be executed to resolve various anticipated complication. In this phase also, students’ performance and comprehension capacity were observed and recorded. In data analysis phase, the observed results were verified and correlations were recognized. In the final phase, conclusions were established and recommendations for further related pedagogic experiments were introduced.

summary	This paper investigates the use of explicit structures of information in architectural design. Particularly, it approaches the use of diagrams related to cybernetics and information theory in experimental practices in the 1960’s and 1970’s. It analyses the diagram of cybernetic control proposed by the cybernetician Gordon Pask for the Fun Palace, the diagrams produced by the utopian architect Yona Friedman in the conceptual description of the Flatwriter program and Christopher Alexander’s diagrams and his theories of Synthesis of Form and Pattern Language. Finally it establishes a brief parallel between current domestication and use of dataflow programming with the cybernetic diagrams, highlighting differences in their complexity approach.

summary	Agent-based systems have been widely investigated in simulation and modeling. In this paper, it is proposed that agent-based systems can also be developed as generative systems, in which different aspects of performative design can be defined as separate drivers in a proper computational framework. In this manner constrained generating procedures (CGP’s) are studied to integrate the discrete design processes into one system. Subsequently, this generative agent-based design tool is accompanied with generating and constraining mechanism which are informed by material characteristics and fabrication constraints, bringing to the forefront emergent complexity.

summary	Mass customization is pointed as a means of improving a company’s competitiveness, which is an essential trait in Europe’s economic situation of today. This paper reports a mockup implementation of the mass customization paradigm to ceramic tableware design, through the use of shape grammars, parametric modelling and rapid prototyping. Focus is emphasized on the initial development of a parametric shape grammar as a design system, operating on curved surfaces and solids. Mapping operations are suggested for dealing with the formal complexity of these shapes. This initial academic experiment poses as a first step into the development of a mass customization system that is expected to meet industry standards.

summary	The principle of Augmented Iterations is to create shapes of progressively higher complexity, thanks to a fast neuronal selection of shapes among several possible evolving designs. Such a process is made possible by the use of a brain signal known as P300, which appears when a user perceives a rare and relevant stimulus and can be used for intricate pattern recognition and human computation systems. We aim at using this P300 signal to identify the (re)cognition of shapes or designs that a user finds almost instantaneously relevant and noticeable, when exposed to a rapid visual flow of variations of such shapes or designs. Using evolutionary algorithms, the shapes identified as those triggering a P300 in the user’s EEG signals is selected and combined to give rise to geometrical aggregations of a higher complexity. These new shapes replace the previous ones in the rapid flow of variations presented to the user, hence iterating the evolutionary design.

summary	For the built environment's transformation we are confronted with complex dynamics connected to economic, ecologic and demographic change (Czerkauer-Yamu et al., 2013; Yamu, 2014). In general, cities are complex systems being a "heterogeneous mosaic" of a variety of cultures and functions, characterised by diverging perceptions and interests (ibid). The juxtaposed perceptions and interests in relation to ongoing spatial processes of change create a particularly complex situation. Thus, for planning processes we are in need of approaches that are able to cope not only with the urban complexity but also allow for participatory processes to empower citizens. This paper presents the approach of using Digital Twins in virtual reality (VR) for civic engagement in urban planning, enriched with quantitative and qualitative empirical data as one promising approach to tackle not only the complexity of cities but also involve citizens in the planning process.
