title	Emergent Structures Assembled by Large Swarms of Simple Robots

summary	Traditional architecture relies on construction processes that require careful planning and strictly defined outcomes at every stage; yet in nature, millions of relatively simple social insects collectively build large complex nests without any global coordination or blueprint. Here, we present a testbed designed to explore how emergent structures can be assembled using swarms of active robots manipulating passive building blocks in two dimensions. The robot swarm is based on the toy “bristlebot”; a simple vibrating motor mounted on top of bristles to propel the body forward. Since shape largely determines the details of physical interactions, the robot behavior is altered by carefully designing its geometry instead of uploading a digital program. Through this mechanical programming, we plan to investigate how to tune emergent structural properties such as the size and temporal stability of assemblies. Alongside a physical testbed with 200 robots, this work involves comprehensive simulation and analysis tools. This simple, reliable platform will help provide better insight on how to coordinate large swarms of robots to construct functional structures.

summary	Textiles are widely used in architecture for tensile structures, as they are lightweight and can easily span large distances. These structures typically require an external framework for a support. Inflatable structures are self-supporting but are limited to relatively simple forms or require complex and predetermined cut patterns. The development of an adaptive and programmable textile system with an integrative method for pneumatic activation would create a novel self-supporting structure with high degree of design and architectural potential. This creates a highly integrative hybrid system where the generic pneumatic membranes are constrained by the differentiated knitted textile skin that is stretched in several directions under air pressure. This allows for an innovative, lightweight, easily transportable design, where the preprogrammed knitting pattern defines the structure, geometry and formation, activated under pneumatic pressure.

title	Discrete Computational Methods for Robotic Additive Manufacturing: Combinatorial Toolpaths

summary	The research presented in this paper is part of a larger, emerging body of research into large-scale 3D printing. The research attempts to develop a computational design method specifically for large-scale 3D printing of architecture. Influenced by the concept of Digital Materials, this research is situated within a critical discussion of what fundamentally constitutes a digital object and process. This requires a holistic understanding, taking into account both computational design and fabrication. The intrinsic constraints of the fabrication process are used as opportunities and generative drivers in the design process. The paper argues that a design method specifically for 3D printing should revolve around the question of how to organize toolpaths for the continuous addition or layering of material. Two case-study projects advance discrete methods as efficient ways to compute a continuous printing process. In contrast to continuous models, discrete models allow users to serialize problems and errors in toolpaths. This allows a local optimization of the structure, avoiding the use of global, computationally expensive, problem-solving algorithms. Both projects make use of a voxel-based approach, where a design is generated directly from the combination of thousands of serialized toolpath fragments. The understanding that serially repeated elements can be assembled into highly complex and heterogeneous structures has implications stretching beyond 3D printing. This combinatorial approach for example also becomes highly valuable for construction systems based on modularity and prefabrication.

title	Accepting the robotic other: Why real dolls and spambots suggest a near-future shift in architecture’s architecture
source	International Journal of Architectural Computing vol. 14 - no. 1, 6-15
summary	With weak Artificial Intelligence in the pockets of the majority of American adults, a societal introduction of a strong Artificial Intelligence or sentience seems close. Although the “intelligence” of our phones’ intelligence can be laughably brittle, the learning capacity demonstrated by the Internet of Things suggests more robust intelligence is on the way, and some would say it has already arrived. Several private technology firms have asserted that a robust Artificial Intelligence already exists and thought leaders within computation are lining up to ensure that it is not evil. Regardless of the morality of Artificial Intelligence, if our charge as architects is to design occupiable space, then we need to consider post-anthropocentric ecologies as well as how to adapt our design strategies to reflect inclusion of other species. This article describes two linked lines of thought, a meditation on the pending societal inclusion of the robotic other and why that robotic sentience may arrive from an unexpected origin and can reshape how we conceive of architecture itself.

title	Exploring Weaire-Phelan through Cellular Automata: A proposal for a structural variance-producing engine
source	SIGraDi 2016 [Proceedings of the 20th Conference of the Iberoamerican Society of Digital Graphics - ISBN: 978-956-7051-86-1] Argentina, Buenos Aires 9 - 11 November 2016, pp.710-714
summary	Complex forms and structures have always been highly valued in architecture, even much before the development of computers. Many architects and engineers have strived to develop structures that look very complex but at the same time are relatively simple to understand, calculate and build. A good example of this approach is the Beijing National Aquatics Centre design for the 2008 Olympic Games, also known as the Water Cube. This paper presents a proposal for a structural variance-producing engine using cellular automata (CA) techniques to produce complex structures based on Weaire-Phelan geometry. In other words, this research evaluates how generative and parametric design can be integrated with structural performance in order to enhance design flexibility and control in different stages of the design process. The method we propose was built in three groups of procedures: 1) we developed a method to generate several fits for the two Weaire-Phelan polyhedrons using CA computation techniques; 2) through the finite elements method, we codify the structural analysis outcomes to use them as inputs for the CA algorithm; 3) evaluation: we propose a framework to compare how the final outcomes deviate for the good solutions in terms of structural performance and rationalization of components. We are interested in knowing how the combination of the procedures could contribute to produce complex structures that are at the same time certain rational. The system developed allows the structural analysis of structured automatically generated by a generative system. However, some efficient solutions from the structural performance point of view do not necessarily represent a rational solution from the feasibility aspects.

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	Growth Based Fabrication Techniques for Bacterial Cellulose: Three-Dimensional Grown Membranes and Scaffolding Design for Biological Polymers
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. 488-495

summary	Self-assembling manufacturing for natural polymers is still in its infancy, despite the urgent need for alternatives to fuel-based products. Non-fuel based products, specifically bio-polymers, possess exceptional mechanical properties and biodegradability. Bacterial cellulose has proven to be a remarkably versatile bio-polymer, gaining attention in a wide variety of applied scientific applications such as electronics, biomedical devices, and tissue-engineering. In order to introduce bacterial cellulose as a building material, it is important to develop bio-fabrication methodologies linked to material-informed computational modeling and material science. This paper emphasizes the development of three-dimensionally grown bacterial cellulose (BC) membranes for large-scale applications, and introduces new manufacturing technologies that combine the fields of bio-materials science, digital fabrication, and material-informed computational modeling. This paper demonstrates a novel method for bacterial cellulose bio-synthesis as well as in-situ self-assembly fabrication and scaffolding techniques that are able to control three-dimensional shapes and material behavior of BC. Furthermore, it clarifies the factors affecting the bio-synthetic pathway of bacterial cellulose—such as bacteria, environmental conditions, nutrients, and growth medium—by altering the mechanical properties, tensile strength, and thickness of bacterial cellulose. The transformation of the bio-synthesis of bacterial cellulose into BC-based bio-composite leads to the creation of new materials with additional functionality and properties. Potential applications range from small architectural components to large structures, thus linking formation and materialization, and achieving a material with specified ranges and gradient conditions, such as hydrophobic or hydrophilic capacity, graded mechanical properties over time, material responsiveness, and biodegradability.

title	Implementing the General Theory for Finding the Lightest Manmade Structures Using Voronoi and Delaunay

summary	In previous efforts, the foundation of a general theory that searches for finding lightest manmade structures using the Delaunay diagram or its dual the Voronoi diagram was set (Ezzat, 2016). That foundation rests on using a simple and computationally cheap Centroid method. The simple Centroid method is expected to play a crucial role in the more sophisticated general theory. The Centroid method was simply about classifying a cloud of points that represents specific load case/s stresses on any object. That classification keeps changing using mathematical functions until optimal structures are found. The point cloud then is classified into different smaller points' groups; each of these groups was represented by a single positional point that is related to the points' group mean. Those representational points were used to generate the Delaunay or Voronoi diagrams, which are tested structurally to prove or disprove the optimality of the classification. There was not a single optimized classification out of that process but rather a family of them. The point cloud was the input to the centroid structural optimization, and the family of the optimized centroid method is the input to our proposed implementation of the general theory (see Figure 1). The centroid method produced promising optimized structures that performed from five to ten times better than the other tested variations. The centroid method was implemented using the two structural plugins of Millipede and Karmaba, which run under the environment of the Grasshopper plugin. The optimization itself is done using the grasshopper's component of Galapagos.

summary	Contemporary advanced simulation software allow for a higher accuracy in the understanding of material behaviour. The increase in computational power is enabling designers to get much closer to real time physical simulations, which facilitates the inheritance of those tools in their design workflows.However, the use of those tools is normally limited to a series of specific steps within the entire workflow, rather than a feature integrated in the design process itself.Softmodelling is an open source Java application which aims to bridge this gap by seamlessly integrating physical simulations in every step of the design process, giving designers the ability to not only test structural behaviours of a given output, but also allow them to design while taking both structural stability and material behaviour into account at every stage.This paper will discuss the design and evolution of the software, as well as showcase physical prototypes which explore the possibilities of such design methods. These projects are fundamental in materialising the evolution of Softmodelling, towards becoming an application that does not only enable the design of flexible elements, but also facilitates their manufacturing and assembly into large scale structures.

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

title	What Bricks Want: Machine Learning and Iterative Ruin

summary	Ruin has a bad name. Despite the obvious complications, failure provides a rich opportunity—how better to understand a building’s physicality than to watch it collapse? This paper offers a novel method to exploit failure through physical simulation and iterative machine learning. Using technology traditionally relegated to special effects, we can now understand collapse on a granular level: since modern-day physics engines track object-object collisions, they enable a close reading of the spatial preferences that underpin ruin. In the case of bricks, that preference is relatively simple—to fall. By idealizing bricks as rigid bodies, one can understand the effects of gravitational force on each individual brick in a masonry structure. These structures are sometimes able to ‘settle,’ resulting in a stable equilibrium state; in many cases, it means that they will simply collapse. Analyzing ruin in this way is informative, to be sure, but it proves most useful when applied in series. The evolutionary solver described in this paper closely monitors the performance of constituent bricks and ensures that the most successful structures are emulated by later generations. The tool consists of two parts: a user interface for design and the solver itself. Once the architect produces a potential design, the solver performs an evolutionary optimization; after a few hundred iterations, the end result is a structurally sound version of the unstable original. It is hoped that this hybrid of top-down and bottom-up design strategies offers an architecture that is ultimately strengthened by its contingencies.

summary	The integration of industrial robots in the creative art industry has increased in recent years. Implementing both brick stacking robotic fabrication, following a curved wall, and generating an image viewed from a single point, by rotating the bricks around their centres, has yet to be studied. The goal of this research is to develop a functional, parametric working model and a workflow that ensure easy manipulation and control of the desired outcome via parameters. This paper shows a workflow for the automatic generation of anamorphic structures on a curved wall by utilizing modular brick-like elements. As a result, a code for the robot controller and the position of the structure during fabrication are provided.

summary	Brick has been used in construction since ancient times and has been respected among other tectonic materials through out the history. Novel technologies recently have opened new horizons in using brick in architectural design. This paper investigates innovative implementation of bricks in kinetic architecture. Kinetic structures usually employ complex and high-cost mechanisms to come into force and their movements might be limited to some conditions. By the use of magnet in digital design, this research examines new methods for performing simple and affordable kinetic structures so as to create interactive relations between architecture and human being. Magnetic energy is applied in two ways to move a roof made of brick which is considered a heavy and masonry material. Consequently, it represents the hidden potentials of magnet as a renewable source of energy.

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	Bending-Active Plates: Form-Finding and Form-Conversion

summary	With this paper, the authors aim to contribute to the discourse on bending-active structures by highlighting two different design methods, form-finding and form-conversion. The authors compare the two methods through close analysis of bending-active plate structures, discussing their advantages and disadvantages based on three built case studies. This paper introduces the core ideas behind bending-active structures, a rather new structural system that makes targeted use of large elastic deformations to generate and stabilize complex geometrical forms based on initially planar elements. Previous research has focused mainly on form-finding. As a bottom-up approach, it begins with flat plates and recreates the bending and coupling process digitally to gradually determine the final shape. Form-conversion, conversely, begins with a predefined shape that is then discretized by strategic surface tiling and informed mesh subdivision, and which in turn considers the geometrical and structural constraints given by the plates. The three built case studies exemplify how these methods integrate into the design process. The first case study applies physical and digital form-finding techniques to build a chaise lounge. The latter two convert a desired shape into wide-spanning constructions that either weave multiple strips together or connect distant layers with each other, providing additional rigidity. The presented case studies successfully prove the effectiveness of form-finding and form-conversion methods and render a newly emerging design space for the planning, fabrication, and construction of bending-active structures.

summary	The objective of this paper is to clarify how value creation can be a part of architectural design and end-products when using the new emerging technology of additive manufacturing. Different kinds of values that have emerged from the research material have been analysed and summarised using selected case studies of recent building-scale projects. In applying this technique to architecture, the result can be visually and functionally novel, smarter and more sustainable buildings or products. A new individually manufactured or customised architecture can be created to serve different cultural and well-being needs cost effectively and without any waste. This new production method can lead to unique joint structures with the use of traditionally produced new or old building parts to enhance architecture, prevent climate change or aid environmental issues. However, most research projects and applications done by commercial companies are at the early stages.

title	Composite Systems for Lightweight Architectures: Case studies in large-scale CFRP winding

summary	The introduction of lightweight Carbon Fiber Reinforced Polymer (CFRP) based systems into the discipline of architecture and design has created new opportunities for form, fabrication methodologies and material efficiencies that were previously difficult if not impossible to achieve through the utilization of traditional standardized building materials. No longer constrained by predefined material shapes, nominal dimensions, and conventional construction techniques, individual building components or entire structures can now be fabricated from a single continuous material through a means that best accomplishes the desired formal and structural objectives while creating minimal amounts of construction waste and disposable formwork. This paper investigates the design, fabrication and structural potentials of wound, pre-impregnated CFRP composites in architectural-scale applications through the lens of numeric and craft based composite winding implemented in two unique research projects (rolyPOLY + Cloud Magnet). Fitting into the larger research agenda for the CFRP-based robotic housing prototype currently underway in the “One Day House” initiative, these two projects also function as a proof of concept for CFRP monocoque and gridshell based structural systems. Through a rigorous investigation of these case studies, this paper strives to answer several questions about the integration of pre-impregnated CFRP in future full-scale interventions: What form-finding methodologies lend themselves to working with CFRP? What are the advantages and disadvantages of working with pre-impregnated CFRP tow in large-scale applications? What are efficient methods for the placement of CFRP fiber on-site? As well as how scalable is CFRP?

title	Robotic Fabrication of Structural Performance-based Timber Gridshell in Large-Scale Building Scenario
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 196-205
doi	https://doi.org/10.52842/conf.acadia.2016.196
summary	This paper investigates the potential of a digital geometry system to integrate structural performance-based design and robotic fabrication in the scenario of building a large-scale non-uniform timber shell. It argues that a synthesis of multi-objective optimization, design and construction phases is required in the realization of timber shell construction in architecture practice in order to fulfill the demands of building regulation. Confronting the structural challenge of the non-uniform shell, a digital geometry system correlates all the three phases by translating geometrical information between them. First, a series of structural simulations and experimentations with different objectives are executed to inform the particular shape and tectonic details of each shell component based on its local condition in the geometrical system. Then, controlled by the geometrical system, a hybrid process of different digital fabrication technologies, including a customized robotic timber mill, is established to enable the manufacture of the heterogeneous shell components. Ultimately, the Timber Structure Enterprise Pavilion as the demonstration and evaluation of this method is fabricated and assembled on site through a notational system to indicate the applicability of this research in practical scenarios.

title	3D Digital Reconstructions of Lost Buildings - A first critical framing

summary	This paper presents a first critical framing of 3D digital reconstructions of lost buildings, hence focusing on reconstructions using 3D models. This critical framing is constituted by reflections on definitions, concepts, methodologies and digital technologies. Much experimentation in the digital reconstruction of lost buildings has produced valuable results during the last twenty years, but the variety of methods, software types, and purposes should be reorganized into clear operational protocols to allow sharing of information and collaboration across disciplines. We have therefore investigated the diverse approaches towards digital reconstructions of lost buildings and found that digital reconstructions are not typically aimed at simple visualizations: they are often further developed in virtual environments, information systems and tools for simulations and analysis. In this sense they are not products but instruments for further research and/or heritage conservation. Counter the large number of theoretical positions, methods and tools specific to different disciplines, such as architecture and archaeology, we can find the almost total absence of a comprehensive critical assessment. This paper, which is part of a larger project, intends to open and articulate a debate on how to define, analyze and critically systematize the methodologies for the digital reconstruction of lost buildings.
