title	A Method for Generating Regular Grid Configurations on Free-From Surfaces for Structurally Sound Geodesic Gridshells

summary	Gridshells are highly efficient, lightweight structures which can span long distances with minimal use of material (Vassallo & Malek 2017). One of the most promising and novel categories of gridshells are bending-active (elastic) systems (Lienhard & Gengnagel 2018), which are composed of flexible members (Kuijenhoven & Hoogenboom 2012). Timber elastic gridshells can be site-sprung or sequentially erected (geodesic). While a lot of research focus is on the site-sprung ones, the methods for design of sequentially-erected geodesic gridshells remained underdeveloped (Cichocka 2020). The main objective of the paper is to introduce a method of generating regular geodesic grid patterns on free-form surfaces and to examine its applicability to design structurally feasible geodesic gridshells. We adopted differential geometry methods of generating regular bidirectional geodesic grids on free-form surfaces. Then, we compared the structural performance of the regular and the irregular grids of the same density on three free-form surfaces. The proposed method successfully produces the regular geodesic grid patterns on the free-form surfaces with varying curvature-richness. Our analysis shows that gridshells with regular grid configurations perform structurally better than those with irregular patterns. We conclude that the presented method can be readily used and can expand possibilities of application of geodesic gridshells.

summary	As part of an ongoing research project, this Paper is intended to present some of the main questions emerged when preparing a series of experiments for the generation and arrangement of facade elements in mass customized dwellings. In general, two differing approaches have been tried in panelization of regular and irregular facades in buildings. The first one is based on dimensional coordination strategies and is regarded as being the most efficient in terms of material usage and production rationalization. The other is derived from the more open strategy of deriving individual panel dimensions from a UV grid and its transformations.

summary	The Emergent Reefs project thrives on the potential that emerge from a coherent utilization of the environment’s inherent ecological structure for its own transformation and evolution, using an approach based on digitally simulated ecosystems and sparkled by the possibilities and potential of large-scale 3D printing technology. Considering tourism as an inevitable vector of environmental change, the project aims to direct its potential and economic resources towards a positive transformation, providing a material substrate for the human-marine ecosystem integration with the realization of spaces for an underwater sculpture exhibition. Such structures will also provide a pattern of cavities which, expanding the gradient of microenvironmental conditions, break the existing homogeneity in favor of systemic heterogeneity, providing the spatial and material preconditions for the repopulation of marine biodiversity. Starting from a digital simulation of a synthetic local ecosystem, a generative technique based on multi-agent systems and continuous cellular automata (put into practice from the theoretical premises in Alan Turing’s paper “The Chemical basis of Morphogenesis” through reaction-diffusion simulation) is implemented in a voxel field at several scales giving the project a twofold quality: the implementation of reaction diffusion generative strategy within a non-isotropic 3-dimensional field and integration with the large-scale 3D printing fabrication system patented by D-Shape®. Out of these assumptions and in the intent of exploiting the expressive and tectonic potential of such technology, the project has been tackled exploring voxel-based generative strategies. Working with a discrete lattice eases the simulation of complex systems and processes across multiple scales (including non-linear simulations such as Computational Fluid-Dynamics) starting from local interactions using, for instance, algorithms based on cellular automata, which then can be translated directly to the physical production system. The purpose of Emergent-Reefs is to establish, through strategies based on computational design tools and machine-based fabrication, seamless relationships between three different aspects of the architectural process: generation, simulation and construction, which in the case of the used technology can be specified as guided growth.

summary	The emergence of quasi-periodic tiling theories in mathematics and material science is revealing a new class of symmetry, which had never been accessible before. Because of their astounding visual and structural properties, quasi-periodic symmetries can be ideally suited for many applications in art and architecture; providing a rich source of ideas for articulating form, pattern, surface and structure. However, since their discovery, the unique long-range order of quasi-periodic symmetries, is still posing a perplexing puzzle. As rule-based systems, the ability to algorithmically generate these complicated symmetries can be instrumental in understanding and manipulating their geometry. Recently, the discovery of quasi-periodic patterns in ancient Islamic architecture is providing a unique example of how ancient mathematics can inform our understanding of some basic theories in modern science. The recent investigation into these complex and chaotic formations is providing evidence to show that ancient designers, by using the most primitive tools (a compass and a straightedge) were able to resolve the complicated long-range principles of ten-fold quasi-periodic formations. Derived from these ancient principles, this paper presents a computational model for describing the long-range order of octagon-based quasi-periodic formations. The objective of the study is to design an algorithm for constructing large patches of octagon-based quasi-crystalline formations. The proposed algorithm is proven to be successful in producing an infinite and defect-free covering of the two-dimensional plane.

title	Envelope tesselation with stochastic rotation of 4-fold penttiles

summary	The challenge of developing adaptive, responsive low-energy architecture requires new knowledge about the complex and dynamic interaction between envelope architecture and optimisation between competing environmental performance metrics. Advances in modelling the geometry of building envelopes and control technologies for adaptive buildings now permit the sophisticated evaluation of alternative envelope configurations for a set of performance criteria. This paper reports on a study of the parametric control of a building envelope based on moveable façade components, acting as a shading device to reduce thermal gain within the building. This is investigated using a novel pentagonal tiling strategy considering the component design, tessellation and control methods.

title	Rationalisation of freeform façades: A technique for uniform hexagonal panelling
doi	https://doi.org/10.52842/conf.caadria.2012.243
source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 243–252
summary	This paper is an account of the façade rationalisation strategy developed at Gehry Technologies for mitigating the tradeoffs between project constructability and the aesthetic implications of arranging flat panels over a complex surface. The strategy outlined was developed as the result of the digital building delivery of the Museo Soumaya façade in Mexico City designed by Fernando Romero LAR. This report documents the development process of a method for obtaining relevant construction information flows enabling the assembly of the façade system by a third-party sub-contractor in support of the façade system coordination. This report concludes on a method using bespoke software for extending the parametric modelling system Digital Project™ in the design support role of obtaining an aesthetically pleasing arrangement of flat hexagonal panels over a freeform surface.

summary	For most architects, it is not easy to transform their freeform designs into buildable constructions without precise knowledge on a specifi c material and its construction process.A workfl ow is introduced in this paperand it could be adopted by architects concerning the works of predicting the tiling results in the earliest design stage.The workfl ow involves pre-processing which could help architects design rational surfaces, thus saving a lot of work in the paneling process later on. The physically based modeling engine will simulate the constraints of a pre-selected material and therefore ensures a feasible result. The post-process involves visual feedback of the result as well as data formatting which help to establish a seamless connection between construction processes.

summary	Low Fidelity engages in the translational discrepancies that occur through mediums of architectural representation, not as instances of dilemma but as opportunities to subdue tautology and augment the seductive latency of representation(1). Where some might contend the discrepant as unlawful, the methodology that this thesis argues for engages the digital and machinic, and explores the translational discrepancies that challenge and interrupt our interface with matters of materialization and excite material propensities. The discrepant becomes a dynamic catalyst through the engagement of tools and techniques that subvert the homogeneity of digital design. Low Fidelity engages the sphere of translation by reevaluating the role of architectural representation as generator and generated its originations and its limitations. In an attempt to negotiate the digital and physical, this thesis situates itself within the feedback loop between the mediums of translation through ideas their formal logics, material propensities and back again.

title	Digital and Physical Tools for Industrial Robots in Architecture: Robotic Interaction and Interfaces
source	International Journal of Architectural Computing vol. 10 - no. 4, 541-554
summary	The development of digital and physical tools is highly dependent on interfaces, which define the terms of interaction both between humans and machines, as well as between machines and other machines.This research explores how new, advanced human machine interfaces, that are built upon concepts established by entertainment electronics can enhance the interaction between users and complex, kinematic machines. Similarly, physical computing greatly innovates machine-machine interaction, as it allows designers to easily customize microcontroller boards and to embed them into complex systems, where they drive actuators and interact with other machines such as industrial robots.These approaches are especially relevant in the creative industry, where customized soft- and hardware is now enabling innovative and highly effective fabrication strategies that have the potential to compete with high-tech industry applications.

summary	Loose granulates are a relevant yet rarely deployed architectural material system. Their significance lies in their capacity to combine fluid-like amorphousness with solid-like rigidity, resulting in potential architectural structures capable of continuous reconfi guration. In addition aggregates allow for functional grading. Especially if custom designed concave particles are used, full-scale architectural structures can be poured using a six-axis industrial robot, combining the precise travel of the emitter-head with the self-organizational capacity of granular substances. In this context, the paper proposes Rigid-Body Dynamics (RBD) simulations as a design-tool for the robotic pouring of loose granular structures. The notions of material and machine computation are introduced and RBD is explained in greater detail. A set of small tests is conducted to investigate the advantages and disadvantages of a specifi c RBD software. Conclusively, further areas of research are outlined.

title	An Integral Approach to Structural Optimization and Fabrication
doi	https://doi.org/10.52842/conf.acadia.2012.491
source	ACADIA 12: Synthetic Digital Ecologies [Proceedings of the 32nd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-62407-267-3] San Francisco 18-21 October, 2012), pp. 491-497
summary	Abstract Integral structural optimization and fabrication seeks the synthesis of two original approaches; that of topological optimization (TO) and robotic hotwire cutting (HWC). TO allows for the reduction of up to 70% of the volume of concrete to support a given structure. A strength of the method is that it allows to come up with structural designs that lie beyond the grasp of traditional means of design. A design space is a discretized volume, delimiting where the optimization will take place. The number of cells used to discretize the design space thus sets the resolution of the TO. While the approach of the application of TO as a constitutive design tool centers on structural aspects in the design phase, the outcome of this process are structures that cannot be realized within a conventional budget. As such the ensuing design is optimal in a narrow sense; whilst optimal structurally though, construction can be prove to be prohibitively expensive. This paper reports ongoing research efforts on the development of a cost effective methodology for the realization of TO concrete structures using HWC.

summary	Integral structural optimization and fabrication seeks the synthesis of two original approaches; that of topological optimization (TO) and robotic hotwire cutting (HWC) (Mcgee 2011). TO allows for the reduction of up to 70% of the volume of concrete to support a given structure (Sondergaard & Dombernowsky 2011). A strength of the method is that it allows to come up with structural designs that lie beyond the grasp of traditional means of design. A design space is a discretized volume, delimiting where the optimization will take place. The number of cells used to discretize the design space thus sets the resolution of the TO. While the approach of the application of TO as a constitutive design tool centers on structural aspects in the design phase (Xie 2010), the outcome of this process are structures that cannot be realized within a conventional budget. As such the ensuing design is optimal in a narrow sense; whilst optimal structurally though, construction can be prove to be prohibitively expensive.

summary	In this paper, viable applications of mobile robotic units on construction sites are explored. While expanding on potential objectives for in-situ fabrication in the construction sector, the intention is also to build upon innovative man-machine interaction paradigms to deal with the imprecision and tolerances often faced on construction sites. By combining the precision of the machine with the cognitive environmental human skills, a simple but effective mobile fabrication system is experimented for the building of algorithmically designed additive assemblies that would not be possible through conventional manual methods if the large amount of individual building blocks and the size of the structure to be built are taken into account. It is believed that this new approach to man-machine collaboration, aimed at a deeper integration of human ability with the strengths of digitally controlled machines, will result in advances in the construction sector, thus opening up new design and application fields for architects and planners.

title	Robotic Plaster Carving: Formalizing subtractive detailing of plaster surfaces for construction and crafts

summary	Plaster has been a fundamental material in numerous interior and exterior applications in architectural construction due to its fire-resistant properties and capabilities for intricate detailing. Moreover, prior to the widespread adoption of computer-aided design tools, plaster played a crucial role in historic preservation and architectural education (Mankouche & Schulte, 2012). While the use of decorative plaster elements in architectural construction has waned in popularity, the renewed interest in plaster within the context of advanced robotic fabrication offers a compelling basis for research. This paper presents an investigation into robotic plaster carving for adding detail and texture to plaster surfaces. Within the scope of this study, we identify and systematically examine various fabrication and material parameters for emergent geometries and fabrication defects, subsequently formalizing this robotic workflow for diverse applications in construction and crafts. Among these parameters, we primarily concentrate on toolpath geometry, tool orientation, carving speed, carving profile, and aggregation of carving strokes. Through this bottom-up approach, our objective is to enhance the understanding of tool-material interaction during the fabrication process and achieve improved control over the resulting artifact. Building on these insights, we demonstrate how the proposed robotic plaster carving workflow can be employed for subtractive surface detailing in architectural construction and digital crafts.

summary	From the beginning of digital revolution, structural surfaces drew significant attention as a realm that interweaves formal explorations, form-finding and structural optimization. However, after successful experimentation in the virtual domain, it became evident that some of the main challenges lay on how to translate these structural forms into architectural assemblies at the scale of buildings. The development of digital fabrication is crucial in this task, as means to overcome traditional constraints such as need for modular pieces, scaffolding and optimal assembly sequences.This research focuses on digital workflows that combine form finding with robotic fabrication, surface tessellation and panelization. In the past years, the use of digital tools to assemble identical modules into complex formations has achieved significant results for loadbearing walls. Expanding this line of research, the proposed fabrication system carries these experiments on additive fabrication into the production of structural surfaces. The assembly sequence involves a two-step fabrication: off-site panel manufacturing and on-site assembly. The main components of the system consist of two triangular ceramic pieces that provide structural resistance, refined surface finish, and formwork for thin reinforced-concrete layer. Panelization strategies reduce the requirements on-site work and formwork.The paper describes background research, concept, construction process, methodology, results and conclusions.

summary	The paper presents the current development of an ongoing research project about the integration of robotic fabrication strategies in computational design through morphological and functional principles derived from natural systems. Initially, a developed plate structure material system based on robotically fabricated fi nger joints is being informed by biomimetic principles from the sea urchin Clypeasteroida in order to be able to adapt effi ciently to its building environment. Consequently, the paper’s main focus lies on translating the biomimetic design principles into a computational design tool, also integrating fabrication parameters as well as structural and architectural demands. The design tool’s capability to integrate these parameters is shown by the design, development and realization of a full-scale research pavilion. The paper concludes with discussing the performative capacity of the developed material system and the introduced methodology.

source	International Journal of Architectural Computing vol. 10 - no. 3, 423-438
summary	Contour Crafting is a digitally controlled construction process invented by Professor Behrokh Khoshnevis that fabricates components directly from computer models, using layered fabrication technology. By obviating the need for formwork used in traditional concrete construction, CC can reduce costs and construction times significantly. The technique has great potential as a robotic form of construction reliant on relatively minimal human labor as a form of construction in relatively hazardous environments, such as the Moon with its radiation levels that can prove highly damaging. Current research funded by NASA has been exploring the potential for using CC on the Moon to build structures making use of readily available regolith that is found in great abundance on the surface of the Moon. This article offers an overview of this research and evaluates the merits of using CC on the Moon.

title	Morphfaux: Probing the Proto-Synthetic Nature of Plaster Through Robotic Tooling

summary	Morphfaux is an applied research project that revisits the virtually lost craft of plaster to explore its potential for producing thickened architectural environments through the use of contemporary digital technology. The research challenges the flatness of modern, standardized dry wall construction and explores plaster’s malleability as a material that can be applied thick and thin, finished to appear smooth or textured, and tooled while liquid or cured. If the invention of industrialized modern building products such as drywall led to the demise of the plasterer as a tradesperson, our research seeks alliances between the abilities of the human hand and those of automation. By transforming historic methods using new robotic tools, Morphfaux has broadened the possibilities of architectural plaster. While our research has produced forms not possible by human skill alone, it also clearly illustrates a symbiotic relationship between the human body and robotic machines where human dexterity and robotic precision are choreographed in the production of innovative plastering techniques.

summary	Despite glass’s ubiquity in the modern built environment it is rarely applied in applications requiring complex curvature. The high temperatures and complexity of techniques utilized in forming curved glass panels are typically very expensive to employ, requiring dedicated hard-tooling which ultimately limits the formal variation that can be achieved. This combination of economic and manufacturing barriers limits both the formal possibilities and potentially the overall envelope-performance characteristics of the glazing system. This research investigates a methodology for utilizing reconfigurable tooling to form glass into doubly curved geometries, offering the potential for improved structural and environmental performance in a material that has remained largely unchanged since the advent of its industrial manufacturing. A custom built forming kiln has been developed and tested, integrated through a parametric modeling workflow to provide manufacturing constraint feedback directly into the design process. The research also investigates the post-form trimming of glass utilizing robotic abrasive waterjet cutting, allowing for the output of machine control data directly from the digital model. The potentials of the methodologies developed in this process are shown through the fabrication of a full-scale installation. By integrating material, fabrication, and design constraints into a streamlined computational methodology, the process also serves as a model for a more intuitive production workflow, expanding the understanding of glass as a material with wide-ranging possibilities for a more performative architecture.

title	Robotic reticulations: A method for the integration of multi-axis fabrication processes with algorithmic form-finding techniques

summary	This paper addresses the design and fabrication of non-uniform structural shell systems. Structural shells, particularly gridshells, have a long history but due to their complexity and the accompanying high cost of construction, their application has been limited. The research proposes a method for integrating the design and fabrication processes such that complex double curved reticulated frames can be constructed efficiently, from prefabricated components, requiring significantly less formwork than is typical. A significant aspect of the method has been the development of software tools that allow for both algorithmic form-finding and the direct control of robotic fabrication equipment from within the same modelling package. A recent case-study is examined where the methodology has been applied to construct a reticulated shell structure in the form of a partial vault. Components were prefabricated using 6-axis robotic fabrication equipment. Individual parts are designed such that the assembly of components guides the form of the vault, requiring no centring to create the desired shape. Algorithmically generated machine instructions controlled a sequence of three tool changes for each part, using a single modular fixture, greatly increasing accuracy. The complete integration of computational design techniques and fabrication methodologies now enables the economical deployment of non-uniform structurally optimised reticulated frames.
