title	Material and Machine Computation of Designed Granular Matter: Rigid-Body Dynamics Simulations as a Design Tool for Robotically-Poured Aggregate Structures Consisting of Polygonal Concave Particles

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	Functionally Graded Aggregate Structures: Digital Additive Manufacturing With Designed Granulates
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. 295-304

summary	In recent years, loose granulates have come to be investigated as architectural systems in their own right. They are defined as large numbers of elements in loose contact, which continuously reconfigure into variant stable states. In nature they are observed in systems like sand or snow. In architecture, however, they were previously known only from rare vernacular examples and geoengineering projects, and are only now being researched for their innate material potentials. Their relevance for architecture lies in being entirely reconfigurable and in allowing for structures that are functionally graded on a macro level. Hence they are a very relevant yet unexplored field within architectural design. The research presented here is focused on the potential of working with designed granulates, which are aggregates where the individual particles are designed to accomplish a specific architectural effect. Combining these with the use of a computer-controlled emitter-head, the process of pouring these aggregate structures can function as an alternative form of 3D printing or digital additive manufacturing, which allows both for instant solidification, consequent reconfiguration, and graded material properties. In its first part, the paper introduces the field of research into aggregate architectures. In its second part, the focus is laid on designed aggregates, and an analytical design tool for the individual grains is discussed. The third part presents research conducted into the process of additive manufacturing with designed granulates. To conclude, further areas of investigation are outlined especially with regard to the development of the additive manufacturing of functionally graded architectural structures. 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	An Integral Approach to Structural Optimization and Fabrication

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.

title	In-Situ Robotic Construction: Extending the Digital Fabrication Chain in Architecture

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.

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.

title	Robotic Construction by Contour Crafting: The Case of Lunar Construction
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.

summary	The use of computer-aided design combined with robotics and evolutionary principles of optimization, during the architectural design process, is discussed in this paper. The research is based on the examples of four case studies out of six projects designed during the Experimental Design Studio: ROBO Studio and a parallel seminar on optimization techniques on Architecture for Society of Knowledge Master course at Warsaw University of Technology, Faculty of Architecture. The project’s main goal was to combine robotic prototypes construction with an optimization process executed in parallel within one design procedure. The results of the course and the discussion about the impact of both factors on the architectural design process are presented in this paper.

summary	The paper presents research into computational design processes that integrate not only criteria of physical producibility but also characteristics of design intelligence and performance. In the first part, the use of an industrial robot’s design space for developing differentiated finger joint connections for planar sheets of plywood is being introduced. Subsequently, biomimetics is proposed as a filter for the possible geometric differentiations with respect performative capacities. The second part focuses on the integration of fabricational and biomimetic principles with structural and architectural demands, as well as by the development of a custom digital data structure for the fabrication of finger joint plate structures resulting in the construction of a full scale prototype. The paper concludes with evaluating the tolerances inherent in construction through 3D laser scan validation of the physical model.

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.

summary	In this work we address the fast and economical realization of complex formwork for concrete with the advantage of industrial robot arm. Under economical realization we mean reduction of production time and material effi ciency. The complex form of individual formwork parts can be in our case double curved surface of complex mesh geometry. We propose the fabrication of the formwork by straight or shaped hot wire. We illustrate on several projects different approaches to mould production, where the proposed process demonstrates itself effective. In our approach we deal with the special kinds of modularity and specific symmetry of the formwork.

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.

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.

doi	https://doi.org/10.52842/conf.acadia.2012.315
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.

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

doi	https://doi.org/10.52842/conf.acadia.2012.177
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.

title	Glass Cast: A Reconfigurable Tooling System for Free-Form Glass Manufacturing
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. 287-294
doi	https://doi.org/10.52842/conf.acadia.2012.287
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.

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.

summary	An emerging need for interactive architecture is currently making buildings mutable, flexible in use, and adaptable to changes in climate by introducing robotic systems. However, the feasibility of the seamless integration of building construction details and kinetic robotics has become a critical issue for developing robotic architecture. The objective of this work is to develop a robotic architecture with an emphasis on the integration of cellular robotics with a distributed kinetic building surface. The kinetic building surface integrates an actuating system, a localization and remote control system, which become part of the kinetic building system. This paper presents a systematic framework by reviewing theories and related work of robotic architecture and automated control. An architectural design scheme is proposed to simulate a scenario of application in a physical space. The functionality of the electrical and control system and the integration of the effects of actual construction were examined by a prototype of a kinetic surface. Our prototype presents a feasible construction method, and a prominent energy-saving effect. The potential strength and restrictions of the cellular robotic approach to architectural applications are discussed. The applicability of the prototype system and issues about controlling the behavior of spatial robots are demonstrated in this paper.

summary	Designing the Negative was the title of a Master Studio that took place at the Institute of Architecture and Media of Graz University of Technology during the summer semester of 2012. Students designed and fabricated prototypes of customized concrete formwork as part of their studio assignment. The studio theme forced students to think about digital fabrication with parametric tools in a hands-on fashion. Using robotic technology and hot-wire cutting, students worked with the robot’s constraints (size of the robot’s arm, robot’s axis and tool’s restrictions) to design complex curved elements that could serve as formwork (the negative) for cast concrete elements (the positive). The students were asked to design a production strategy for their cast concrete elements as well as the application of said elements in an architectural scheme. The student projects confirmed the value of a pedagogy that takes on research-relevant questions in an interdisciplinary studio setting and engages students in a process that is best described as digital crafting: it simultaneously addressed the conceptual and technical as well as the material and tactile aspects of digital fabrication and design.
