title	Bio-Inspired Kinetic Curved-Line Folding for Architectural Applications
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.270-279

summary	This paper discusses the development of a bio-inspired compliant mechanism for architectural applications and explains the methodology of investigating movements found in nature. This includes the investigation of biological compliant mechanisms, abstraction, and technical applications using computational tools such as finite element analysis (FEA). To demonstrate the possibilities for building envelopes of complex geometries, procedures are presented to translate and alter the disclosed principles to be applicable to complex architectural geometries. The development of the kinetic façade shading device flectofold, based on the biological role-model Aldrovanda vesiculosa, is used to demonstrate the process. The following paper shows results of FEA simulations of kinetic curved-line folding mechanisms with pneumatic actuation and provides information about the relationship between varying geometric properties (e.g. curved-line fold radii) and multiple performance metrics, such as required actuation force and structural stability.

title	Adaptive Pneumatic Shell Structures - Feedback-driven robotic stiffening of inflated extensible membranes and further rigidification for architectural applications

summary	The paper presents the development of a design framework that aims to reduce the complexity of designing and fabricating free-form inflatables structures, which often results in the generation of very complex geometries. In previous research the form-finding potential of actuated and constrained inflatable membranes has already been investigated however without a focus on fabrication (Otto 1979). Consequently, in established design-to-fabrication approaches, complex geometry is typically post-rationalized into smaller parts and are finally fabricated through methods, which need to take into account cutting pattern strategies and material constraints. The design framework developed and presented in this paper aims to transform a complex design process (that always requires further post-rationalization) into a more integrated one that simultaneously unfolds in a physical and digital environment - hence the term cyber-physical (Menges 2015). At a full scale, a flexible material (extensible membrane, e.g. latex) is actuated through inflation and modulated through additive stiffening processes, before being completely rigidified with glass fibers and working as a thin-shell under compression.

title	Spatial Wire Cutting: Cooperative robotic cutting of non-ruled surface geometries for bespoke building components
source	Living Systems and Micro-Utopias: Towards Continuous Designing, Proceedings of the 21st International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2016) / Melbourne 30 March–2 April 2016, pp. 529-538

summary	The research project Spatial Wire Cutting (SWC) investi- gates a multi-robotic cutting technique that allows for an efficient production of geometrically complex architectural components. Being pursued by the group of Gramazio Kohler Research at ETH Zurich, this approach involves a spatially coordinated movement of two six- axis robotic arms that control the curvature of a hot-wire, which adopts itself against the resistance of the processed material (e.g. pol- ystyrene). In contrast to standard CNC hot-wire cutting processes, in which the cutting medium remains linear, it allows the automated fab- rication of non-ruled, doubly curved surfaces. This pursuit includes the development of a custom digital design and robotic control framework that combines computational simulation and manufactur- ing feedback information. Ultimately, SWC enables a considerably expanded design and fabrication space for complex architectural ge- ometries and their construction through automated robotic technology. This paper addresses the applied workflow and technology 1) such as computational design and simulation, robotic control and adaptive fabrication, 2) results of application within a two-week design and building workshop, and 3) will conclude with further steps of future research.

summary	This paper explains a method will be used during a workshop for constructing complex-curved geometry with quad edge panels. In this workshop, we demonstrate that quad-edge mesh data structure can efficiently be used to construct complex large shapes. With hands-on experiments, we will show a vast variety of shapes can be constructed using square, rectangular, parallelogram and extruded-line shaped panels. In addition, using a system we have recently developed to unfold polygonal mesh, we will demonstrate how desired shapes can be constructed by using laser-cut quadrilateral panels. This approach is particularly suitable to construct complicated sculptural and architectural shapes from anisotropic materials that can only be bended in one direction.

The existing attempts of complex engineering algorithms implementation, as a form finding approach will be discussed. The review of architectural approaches utilising engineering methods will be supplemented by the author's own solution for that particular problem. By intersecting architectural form evaluation with engineering analysis complemented by optimisation algorithms, the new quality of contemporary architecture design process may appears.

title	Parametrically Fabricated Joints: Creating a Digital Workflow
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.412-417
summary	Timber joinery for furniture and architectural purpose has always been identified as a skill or craft. The craft is the demonstration of hand machined skill and precision which is passed down or developed through the iteration of creation and refined reflection. Using digital fabrication techniques provides new, typically unexplored ways of creating and designing joints. It is as if these limitations which bind the ratio of complexity and use are stretched. This means that these joints, from a technical standpoint, can be more advanced than historically hand-made joints as digital machines are not bound by the limitations of the human. The research investigated in this paper explores the ability to create sets of joints in a parametric environment that will be produced with CNC machines, thus redefining the idea of the joint through contemporary tools of creation and fabrication. The research also aims to provide a seamless, digital workflow from the flexible, parametric creation of the joint to the final physical fabrication of it. Traditional joints, more simple in shape and assembly, were first digitally created to ease the educational challenges of learning a computational workflow that entailed the creation and fabrication of geometrically programmed joints. Following the programming and manufacturing of these traditional joints, more advanced and complex joints were created as the understanding of the capabilities of the software and CNC machines developed. The more complex and varied joints were taken from a CAD virtual environment and tested on a 3-axis CNC machine and 3D printer. The transformation from the virtual environment to the physical highlighted areas that required further research and testing. The programmed joint was then refined using the feedback from the digital to physical process creating a more robust joint that was informed by reality.

title	Robotic Fabrication of Non-Standard Material

doi	https://doi.org/10.52842/conf.acadia.2016.x.g4f
summary	This paper illustrates a fabrication methodology through which the inherent form of large non-linear timber components was exploited in the Wood Chip Barn project by the students of Design + Make at the Architectural Association’s Hooke Park campus. Twenty distinct Y-shaped forks are employed with minimal machining in the construction of a structural truss for the building. Through this workflow, low-value branched sections of trees are transformed into complex and valuable building components using non-standard technologies. Computational techniques, including parametric algorithms and robotic fabrication methods, were used for execution of the project. The paper addresses the various challenges encountered while processing irregular material, as well as limitations of the robotic tools. Custom algorithms, codes, and post-processors were developed and integrated with existing software packages to compensate for drawbacks of industrial and parametric platforms. The project demonstrates and proves a new methodology for working with complex, large geometries which still results in a low cost, time- and quality-efficient process.

summary	The paper addresses a specific method for the production of custom-made, differentiated moulds for the realization of a complex, doubly-curved wall element during an international three-week architectural programme, Architectural Association (AA) Summer DLAB. The research objectives focus on linking geometry, structure, and robotic fabrication within the material agency of concrete. Computational workflow comprises the integration of structural analysis tools and real-time form-finding methods in order to inform global geometry and structural performance simultaneously. The ability to exchange information between various simulation, modelling, analysis, and fabrication software in a seamless fashion is one of the key areas where the creation of complex form meets with the simplicity of exchanging information throughout various platforms. The paper links the notions of complexity and simplicity throughout the design and fabrication processes. The aim to create a complex geometrical configuration within the simplicity of a single material system, concrete, presents itself as an opportunity for further discussion and development.

summary	Lighting analysis tools have proven their ability in helping designers provide functional lighting, increase comfort levels and reduce energy consumption in buildings. Consequently, the number of lighting analysis software is increasing and all are competing to provide credible and rigorous analysis. The rapid adoption of parametric design in architecture, however, has resulted in complex forms that make the evaluation of the accuracy of digital analysis more challenging. This study aims to evaluate and compare the performance of daylighting analysis in two industry standard software (Autodesk Revit and 3ds Max) when analysing the daylighting of complex parametric façade patterns. The study has shown that, generally, both Revit and 3ds Max underestimate illuminance values when compared to physical scaled models. 3ds Max was found to outperform Revit when simulating complex parametric patterns, while Revit was found to outperform 3ds Max when simulating simple fenestration geometries. As a general conclusion, the rapid progress of parametric modelling, integrated with fabrication technologies, has made daylighting analysis of complex geometries more challenging. There is a need for more sophisticated algorithms that can handle the increased level of complexity as well as further verification studies to evaluate the accuracy claims made by software vendors.

summary	In this paper, we introduce the Nip and Tuck Method, which provides a general approach to construct complicated shapes without using high-level software and/or without solving complex mathematical problems. Our framework is based on discrete version of Gauss-Bonnet theorem, which states that the sum of vertex angle defect in a given piecewise planar manifold or manifold with boundary mesh surface is independent of the number of vertices, faces and edges. Based on this property, architects and designers can simply introduce negative and positive curvatures in the places they want to obtain desired shapes. We presented Nip and Tuck Architecture to freshman students in beginning level design studios to design arches with modular elements along with other methods. Several groups of students, that chose to use Nip and Tuck approach to obtain individual modules, were able to design and construct unusual small-scale arches.

summary	How might 21st-century computational technologies enhance lighting functionality in architecture? The Groove Light provokes relationships between light and shadow, adding a new dimension to future lighting. A series of distinctive and complex 3D-printed lanterns, which cast identical patterns of geometric shadows, creates the optical illusion that they are floating above a continuous, geometric carpet of shadows. The authors tested this concept in three steps: 1. 3D printability, 2. a lighting test and 3. interactivity. The paper also reports the effectiveness of a selective and custom support strategy for printing overhanging geometries with fused deposition modelling (FDM) 3D printers and further highlights differences between the computational models and physical prototypes in the quest for 'point' light sources.

title	Algorithmic Thinking in Design and Construction - Working with parametric models
source	Parametricism Vs. Materialism: Evolution of Digital Technologies for Development [8th ASCAAD Conference Proceedings ISBN 978-0-9955691-0-2] London (United Kingdom) 7-8 November 2016, pp. 19-28
summary	This paper examines the parametric model in algorithmic design processes, using the outcome of an educational digital design and fabrication course as a case study. In its long history, algorithmic design as a form-finding method, allowed designers to manage complex non-standard associative geometries, suggesting a shift from the digital representation of form, to its systematic representation into a parametric model through code. Rather than a style or a tool, the parametric model is best defined in mathematical terms; in practice it incorporates the organizational logic of the form and the topological associations of its parts, so that a change in its constitutive parameters will invoke a concerted update of the entire model, and, iteratively, formal and structural variations. In a series of design experiments that took place at the School of Architecture of the Technical University of Crete in the spring of 2015, we used parametric models represented into visual code, from the initial conceptual stage to fabrication. From the experience and outcome of this course, we deduced that, compared to other digital formation methods, parametric models allow the designer to constantly interact with the model through the code, producing discreet variations without losing control of the design intentions, by “searching” into a wide range (albeit finite) of virtual results. This suggested a shift in culturally embedded patterns of modernist design thinking.

summary	The present article presents an academic experiment that was designed to promote a productive dialogue between Architecture and Mechatronics. Structured as a joint initiative the project involves fist year students from Architecture and Urban Planning and from Automation and Control Engineering. The process was directed and supervised by professors of both disciplines at the University of Fortaleza, Brazil. The teams of students were invited to explore and mastering basic knowledge in electronics, physical computing and modeling strategies for complex geometries considering real life problems involving both areas. Here we present an open critique to the didactic experiment from the perspective of a group of students.

title	Robotic Sewing: A Textile Approach Towards the Computational Design and Fabrication of Lightweight Timber Shells

doi	https://doi.org/10.52842/conf.acadia.2016.224
summary	Unlike any other building material, timber has seen numerous innovations in design, manufacturing, and assembly processes in recent years. Currently available technology not only allows architects to freely shape building elements but also to define their micro- or macroscopic material make-up and therefore the material itself. At the same time, timber shells have become a focus of research in wood architecture by rethinking both construction typologies and material application. Their main advantage, however, also poses a challenge to its construction: As the shell is both the load-bearing structure as well as enclosure, its segmentation and the individual segment’s connections become increasingly important. Their complex and often differentiated geometries do not allow for standardized timber joints, and with decreasing material thickness, conventional connection techniques become less feasible. The research presented in this paper investigates textile strategies for the fabrication of ultra-lightweight timber shells in architecture. Specifically, a robotic sewing method is developed in conjunction with a computational design method for the development of a new construction system that was evaluated through a large-scale prototype building.

summary	Inspired by the study on traditional weaving handicrafts, this paper focuses on a new weaving structure system that could be used in construction of different organic geometries. A new and viable remeshing algorithm is proposed that a free-form surface could be converted into a certain mesh grid, in which the edges represent the weaving elements, and the vertices represent their joints. The research essentially seeks to integrate the intangible cultural heritage into the construction technique, as well as to narrow the gap between the com- plex geometry with digital fabrication.

summary	This paper discusses the development of an interactive and a responsive Tangible User-Interface (TUI) for parametric and Building Information Modeling (BIM) applications. The prototypes presented in this paper utilizes physical computing systems to establish a flexible and intuitive method to engage digital design processes.The prototypes are hybrid UIs that consist of a digital modeling tool and an artifact. The artifact consists of a control system (sensors, actuators, and microcontrollers) and physical objects (architectural elements). The link between both environments associates physical objects with their digital design information to assist users in the digital design process. The integration of physical computing systems will enable the objects to physically respond to analog input and provide real-time feedback to users. The research aims to foster tangible computing methods to extend the capabilities of digital design tools. The prototypes demonstrate a method that allows architects to simultaneously interact with complex architectural systems digitally and physically.

summary	This paper reports an investigation into the degree of con- sistency between three different methods of sound performance evalu- ation through studying the performance of a built project as a case study. The non-controlled office environment with natural human speech as a source was selected for the subjective experiment and ODEON room acoustics modelling software was applied for digital simulation. The results indicate that although each participant may in- terpret and perceive sound in a particular way, the simulation can pre- dict this complexity to some extent to help architects in designing acoustically better spaces. Also the results imply that architects can make valid comparative evaluations of their designs in an architectur- ally intuitive way, using architectural language. The research acknowledges that complicated engineering approaches to subjective analysis and to controlling the test environment and participants is dif- ficult for architects to comprehend and implement.

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	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.

summary	The increasing population size of cities makes the urban fabric ever more complex and more disintegrated into smaller areas, called neighbourhoods. This project applies methods from geoscience and software engineering to the process of identification of those neighbourhoods. Neighbourhoods, by nature, are defined by connec- tivity, centrality and similarity. Transport and geospatial datasets are used to detect the characteristics of places. An unsupervised learning algorithm is then applied to sort places according to their characteris- tics and detect areas with similar make up: the neighbourhood. The at- tributes can be static like land use or space syntax attributes as well as dynamic like transportation patterns over the course of a day. An un- supervised learning algorithm called Self Organizing Map is applied to project this high dimensional space constituting of places and their attributes to a two dimensional space where proximity is similarity and patterns can be detected – the neighbourhoods. To summarize, the proposed approach yields interesting insights into the structure of the urban fabric generated by human movement, interactions and the built environment. The approach represents a quantitative approach to ur- ban analysis. It reveals that the city is not a polychotomy of neigh- bourhoods but that neighbourhoods overlap and don’t have a sharp edge.
