title	Design Considerations Due to Scale Effects in 3D Concrete Printing
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. 115-124
summary	The effect of scale on different parameters of the 3D printing of concrete is explored through the design and fabrication of a 3D concrete printed pavilion. This study shows a significant gap exists between what can be generated through computer aided design (CAD) and subsequent computer aided manufacturing (generally based on CNC technology). In reality, the 3D concrete printing on the one hand poses manufacturing constraints (e.g. minimum curvature radii) due to material behaviour that is not included in current CAD/CAM software. On the other hand, the process also takes advantage of material behaviour and thus allows the creation of shapes and geometries that, too, can’t be modelled and predicted by CAD/CAM software. Particularly in the 3D printing of concrete, there is not a 1:1 relation between toolpath and printed product, as is the case with CNC milling. Material deposition is dependent on system pressure, robot speed, nozzle section, layer stacking, curvature and more – all of which are scale dependent. This paper will discuss the design and manufacturing decisions based on the effects of scale on the structural design, printed and layered geometry, robot kinematics, material behaviour, assembly joints and logistical problems. Finally, by analysing a case study pavilion, it will be explore how 3D concrete printing structures can be extended and multiplied across scales and functional domains ranging from structural to architectural elements, so that we can understand how to address questions of scale in their design.

title	Emergent Structures Assembled by Large Swarms of Simple Robots
doi	https://doi.org/10.52842/conf.acadia.2016.054

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.

title	Towards New Robotic Design Tools: Using Collaborative Robots within the Creative Industry
doi	https://doi.org/10.52842/conf.acadia.2016.164
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. 164-173
summary	This research documents our initial experiences of using a new type of collaborative, industrial robot in the area of architecture, design, and construction. The KUKA LBR-iiwa differs from common robotic configurations in that it uses seven axes with integrated force-torque sensors and can be programmed in the Java programming language. Its force-sensitivity makes it safe to interact with, but also enables entirely new applications that use hand-guiding and utilize the force-sensors to compensate for high tolerances on building sites, similar to how we manually approach assembly tasks. Especially for the creative industry, the Java programming opens up completely new applications that would have previously required complex bus systems or industrial data interfaces. We will present a series of realized projects that showcase some of the potential of this new type of collaborative, safe robot, and discuss the advantages and limitations of the robotic system.

title	Printing Compound-Curved Sandwich Structures with Robotic Multi-Bias Additive Manufacturing
doi	https://doi.org/https://doi.org/10.1007/978-981-99-8405-3_44
source	Proceedings of the 2023 DigitalFUTURES The 5st International Conference on Computational Design and Robotic Fabrication (CDRF 2023)
summary	A research team at Florida International University Robotics and Digital Fabrication Lab has developed a novel method for 3d-printing curved open grid core sandwich structures using a thermoplastic extruder mounted on a robotic arm. This print-on-print additive manufacturing (AM) method relies on the 3d modeling software Rhinoceros and its parametric software plugin Grasshopper with Kuka-Parametric Robotic Control (Kuka-PRC) to convert NURBS surfaces into multi-bias additive manufacturing (MBAM) toolpaths. While several high-profile projects including the University of Stuttgart ICD/ITKE Research Pavilions 2014–15 and 2016–17, ETH-Digital Building Technologies project Levis Ergon Chair 2018, and 3D printed chair using Robotic Hybrid Manufacturing at Institute of Advanced Architecture of Catalonia (IAAC) 2019, have previously demonstrated the feasibility of 3d printing with either MBAM or sandwich structures, this method for printing Compound-Curved Sandwich Structures with Robotic MBAM combines these methods offering the possibility to significantly reduce the weight of spanning or cantilevered surfaces by incorporating the structural logic of open grid-core sandwiches with MBAM toolpath printing. Often built with fiber reinforced plastics (FRP), sandwich structures are a common solution for thin wall construction of compound curved surfaces that require a high strength-to-weight ratio with applications including aerospace, wind energy, marine, automotive, transportation infrastructure, architecture, furniture, and sports equipment manufacturing. Typical practices for producing sandwich structures are labor intensive, involving a multi-stage process including (1) the design and fabrication of a mould, (2) the application of a surface substrate such as FRP, (3) the manual application of a light-weight grid-core material, and (4) application of a second surface substrate to complete the sandwich. There are several shortcomings to this moulded manufacturing method that affect both the formal outcome and the manufacturing process: moulds are often costly and labor intensive to build, formal geometric freedom is limited by the minimum draft angles required for successful removal from the mould, and customization and refinement of product lines can be limited by the need for moulds. While the most common material for this construction method is FRP, our proof-of-concept experiments relied on low-cost thermoplastic using a specially configured pellet extruder. While the method proved feasible for small representative examples there remain significant challenges to the successful deployment of this manufacturing method at larger scales that can only be addressed with additional research. The digital workflow includes the following steps: (1) Create a 3D digital model of the base surface in Rhino, (2) Generate toolpaths for laminar printing in Grasshopper by converting surfaces into lists of oriented points, (3) Generate the structural grid-core using the same process, (4) Orient the robot to align in the direction of the substructure geometric planes, (5) Print the grid core using MBAM toolpaths, (6) Repeat step 1 and 2 for printing the outer surface with appropriate adjustments to the extruder orientation. During the design and printing process, we encountered several challenges including selecting geometry suitable for testing, extruder orientation, calibration of the hot end and extrusion/movement speeds, and deviation between the computer model and the physical object on the build platen. Physical models varied from their digital counterparts by several millimeters due to material deformation in the extrusion and cooling process. Real-time deviation verification studies will likely improve the workflow in future studies.

title	Using the Phase Space to Design Complexity - Design Methodology for Distributed Control of Architectural Robotic Elements
doi	https://doi.org/10.52842/conf.ecaade.2016.1.413
source	Herneoja, Aulikki; Toni Österlund and Piia Markkanen (eds.), Complexity & Simplicity - Proceedings of the 34th eCAADe Conference - Volume 1, University of Oulu, Oulu, Finland, 22-26 August 2016, pp. 413-422
summary	Architecture that is responsive, adaptive, or interactive can contain active architectural elements or robotic sensor-actuator systems. The consideration of architectural robotic elements that utilize distributed control and distributed communication allows for self-organization, emergence, and evolution on site in real-time. The potential complexity of behaviors in such architectural robotic systems requires design methodology able to encompass a range of possible outcomes, rather than a single solution. We present an approach of adopting an aspect of complexity science and applying it to the realm of computational design in architecture, specifically by considering the phase space and related concepts. We consider the scale and predictability of certain design characteristics, and originate the concept of a formation space extension to the phase space, for design to deal directly with materializations left by robot swarms or elements, rather than robots' internal states. We detail a case study examination of design methodology using the formation space concept for assessment and decision-making in the design of active architectural artifacts.

title	For Time-Continuous Optimisation: Replacing Automation with Interactive Visualisation in Multi-Objective Behavioural Design
doi	https://doi.org/10.52842/conf.caadria.2016.373
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. 373-382
summary	Strategies for optimisation in design normatively assume an artefact end-point, disallowing continuous architecture that engages living systems, dynamic behaviour, and complex systems. In our Flora Robotica investigations of symbiotic plant-robot bio-hybrids, we re- quire computational tools and strategies that help us evaluate designed behaviours, rather than discrete ‘things’. In this paper, we present our strategy of using embodied interaction to facilitate engagement with a scenario’s full scope of possible states and their continuous changes over time. We detail the ways in which this approach to time- continuous optimisation can be broadly impactful for decision- making, especially in architectural systems that aspire to effective dealings with control flows and lifecycle management.

summary	The design studio 'Flying Bricks' was held during the summer semester 2015. Its main objective was to redesign an existing building with the use of facing bricks algorithmically, utilizing algorithmic thinking and programming as a means for form generation. The purpose of having students express their designs in terms of code was to emphasize problem thinking over solution generation, which has several advantages but also disadvantages which we would like to share in this paper. Furthermore, we would like to show how our implementation process worked, so that others can leverage that for their own algorithmic design courses.

title	Crowdthinking
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
summary	The topic "Crowdthinking" reveals the inquiries of researchers about collaborative work, distributed intelligence and collective research. The call focuses on transdisciplinary thinking as a construct based on multiplicity and diversity. All these topics are essential not only in the field of design and architecture, but also in emerging areas of human sciences and arts . Currently, the collaborative design is considered one of the key bases for change in the city and society. In its genesis, it manifests the notion that the world around us is inadequate for many of the needs of the society and from that design can be collectively improved. Such collective research, by combining distributed intelligence, sustainable social development, design cutting edge research, theories and computational strategies, generates a research partnership based on participation and distributed cognition of complex problems. This call proposes an approach in which the results of the experiences can build a model, define or apply axioms and lead to applications. It also looks for emerging conjectures about the process, the creation of computer models and the behaviour of the resulting designs. On the other hand, the need to find solutions that improve the quality of life for the community and sustainable development includes concerns about the integration of the physical and cultural context of cities, mass education and the inclusion of parametric design, digital manufacturing and digital prototyping, and BIM as a system that organizes and ensures the correspondence between the physical urban design and sustainable archetypes. These are some of the concerns in which technology has been contributing to improve the design process by integrating information. This integration optimizes resources and enables the various project professionals to work on the same model, run simulations, improve materializations and evaluate massive amount of data. Projects with greater social and environmental responsibility can be achieved adopting into the teaching and practice this new way of design that anticipates an extensive exchange that wilt foster self-evaluation and reformulation of educational paradigms.

title	20,000 Blocks: Can gameplay be used to guide non-expert groups in creating architecture?
doi	https://doi.org/10.52842/conf.acadia.2016.024
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. 24-33
summary	The paper follows research in engaging groups of non-trained individuals in the creation of architectural designs using games and crowdsourcing for human-directed problem-solving. With the proposed method, architectural experts can encode their design knowledge into custom-developed multiplayer gameplay in Minecraft. Non-expert players then are constrained by this gameplay which guides them to create unique architectural results. We describe a method with three components: guiding rules, verification routines and fast feedback. The method employs a real-time link between the game and structural analysis in Grasshopper to verify the designs. To prove the viability of these results, we use robotic fabrication, where the digital results are brought to reality at scale. A major finding of the work is the suite of tools for calibrating the balance of influence on the resulting designs between the Experts and the Players. We believe that this process can create designs which are not limited to parametrically optimal solutions but could also solve real-world problems in new and unexpected ways.

title	Use of a Low-Cost Humanoid for Tiling as a Study in On-Site Fabrication: Techniques and Methods
doi	https://doi.org/10.52842/conf.acadia.2016.214
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. 214-223
summary	Since the time architecture and construction began embracing robotics, the pre-fab movement has grown rapidly. As the possibilities for new design and fabrication emerge from creativity and need, the application and use of new robotic technologies becomes vital. This movement has been largely focused on the deployment of industrial-type robots used in the (automobile) manufacturing industry for decades, as well as trying to apply these technologies into off-site building construction. Beyond the pre-fab (off-site) conditions, on-site fabrication offers a valuable next step to implement new construction methods and reduce human work-related injuries. The main challenge in introducing on-site robotic fabrication/construction is the difficulty in calibrating robot navigation (localization) in an unstructured and constantly changing environment. Additionally, advances in robotic technology, similar to the revolution of at-home 3D printing, shift the ownership of modes of production from large industrial entities to individuals, allowing for greater levels of design and construction customization. This paper demonstrates a low-cost humanoid robot as highly customizable technology for floor tiling. A novel end-effector design to pick up tiles was developed, along with a localization system that can be applied to a wide variety of robots.

title	Collaborative Construction: Human and Robotic Collaboration Enabling the Fabrication and Assembly of a Filament-Wound Structure

summary	In this paper, we describe an interdisciplinary project and live-exhibit that investigated whether untrained humans and robots could work together collaboratively towards the common goal of building a large-scale structure composed out of robotically fabricated modules using a filament winding process. We describe the fabrication system and exhibition setup, including a custom end effector and tension control mechanism, as well as a collaborative fabrication process in which instructions delivered via wearable devices enable the trade-off of production and assembly tasks between human and robot. We describe the necessary robotic developments that facilitated a live fabrication process, including a generic robot inverse kinematic solver engine for non-spherical wrist robots, and wireless network communication connecting hardware and software. In addition, we discuss computational strategies for the fiber syntax generation and robotic motion planning which mitigated constraints such as reachability, axis limitations, and collisions, and ensured predictable and therefore safe motion in a live exhibition setting. We discuss the larger implications of this project as a case study for handling deviations due to non-standardized materials or human error, as well as a means to reconsider the fundamental separation of human and robotic tasks in a production workflow. Most significantly, the project exemplifies a hybrid domain of human and robot collaboration in which coordination and communication between robots, people, and devices can enhance the integration of robotic processes and computational control into the characteristic processes of construction.

title	From Moving Cube to Urban Interactive Structures - A case study

summary	When thinking about the future vision of a city, having in mind recent development in digital technologies and digital design tools we are inclined to expect new building structures which incorporate this technology to better help us manage the complexity of life, and to simplify our daily lives and tasks. The idea behind this research paper lies in design of such structures, which could be put inside an urban context and engage in creating a built environment that can add more to the quality of life. For us Interactive architecture is architecture that is responsive, flexible, changing, always moving and adapting to the needs of today. The world is becoming more dynamic, society is constantly changing and the new needs it develops need to be accommodated. As a result architecture has to follow. Spaces have to become more adaptive, responsive and nature concerned, while having the ability for metamorphosis, flexibility and interactivity. Taken as a starting point of this idea is a specific module from graduation project in 2014 "The Unexpected city", where it was possible to test out first ideas about interactive and flexible objects in an urban environment.

title	Data Transmission Opportunities for Collaborative Cloud-Based Building Information Modeling
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.907-913
summary	Collaboration within Building Information Modeling process is mainly based on file transfer while BIM data being exchanged in either vendor specific file formats or neutral format using Industry Foundation Classes (IFC). However, since the Web enables Cloud-based BIM services, it provides an opportunity to exchange data via Web transfer services. Therefore, the main objective of this paper is to investigate what features of Cloud interoperability can assist a network-based BIM data transmission for a collaborative work flow in the Architecture, Construction, and Engineering (AEC) industry. This study indicates that Cloud-BIM interoperability needs to deploy major components such as APIs, data transfer protocols, data formats, and standardization to redefine BIM data flow in the Cloud and to reshape the collaboration process.

title	Sensory material architectures: Concepts and methodologies for spatial tectonics and tactile responsivity in knitted textile hybrid structures
source	International Journal of Architectural Computing vol. 14 - no. 1, 63-82
summary	As the knowledge of material computation advances, continuing the seamless integration of design and fabrication, questions beyond materialization can be addressed with a focus on sensing, feedback, and engagement as critical factors of design exploration. This article will discuss a series of prototypes, design methodologies, and technologies that articulate a textile’s micro-architecture, at the scale of fibers and stitches, to instrumentalize simultaneous structural, spatial, and sensory-responsive qualities. The progression of research displays an ever-deepening instrumentalization of fiber structure and its implications to form definition and responsivity, in creating form- and bending-active structures. The research results in a more refined definition of material behavior as the innate phenomena which emerge at the moment of textile fabrication. Ultimately, the architecture, in its materiality and physical, visual, and auditory responsivity, is designed to address specific challenges for children in filtering multiple sensory inputs, an underlying factor of autism spectrum disorder.

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.

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.

summary	Building Performance simulation is escalating towards design optimization worldwide utilizing computational and advanced tools. Egypt has its plan and agenda to adopt new technologies to mitigate energy consumption through various sectors. Energy consumption includes electricity, crude oil, it encompasses renewable and non-renewable energy consumption. Egypt Electricity (EE) consumption by sector percentages is residential (47%), industrial (25%) and commercial (12%), with the remainder used by government, agriculture, public lighting and public utilities (4%). Electricity building consumption has many divisions includes HVAC systems, lighting, Computers and Electronics and others. Lighting share of electricity consumption can vary from 11 to 15 percent in mixed buildings as in our case study which definitely less that the amount used for HVAC loads. This research aims at utilizing shape morphogenesis on facades using geometric shape grammar to enhance daylighting while blocking longwave radiations causing heat stress. Mixed-use building operates in daytime more than night which emphasizes the objective of this study. Results evaluation is referenced to LEED v4.1 and ASHRAE 90.1-2016 window-to-wall ratio calibration and massive wall description. Geometric morphogenesis relies on three main parameters; Pattern (Geometry Shape Grammar: R1, R2, and R3), a reference surface to map from, and a target surface to map to which is the south-western façade of the case study. Enhancing Geo-morph rule is to guarantee flexibility due to the rotation of sun path annually with different azimuth and altitude angles and follow LEED V4.1 enhancements of opaque wall percent for building envelope.

title	A teoria da ludificação e os ambientes responsivos [The theory of ludification and responsive environments]
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.838-843
summary	This paper reports the responsive environments and the Theory of Ludification towards the interaction design using the structure of games on feedback process. It presents an interaction classification that can be reactive, responsive and dialogical based on authors related to cybernetics studies. It exposes the need for rationality in environments as an intrinsic and necessary condition for achieving the interaction. It also uses dialogue and game Vilém Flusser’s concepts to support this argument. Thus, it broadens the contemporary architectural discussion that encompassing communication processes that do not recognize the physical boundaries of the buildings.

title	Narrative Architectural Fiction in Mentally Built Environments

summary	A thin line lies between reality and fiction; what is mentally imagined and what is visualized. It all depends on how ideas and images are perceived or what neurological activity is triggered in the user’s brain. Architects and designers spare no effort or tools in presenting buildings, architecture or designs in all forms or ways that would augment users’ experience whether on the perceptual or the cognitive level and in both the digital or the physical environments. In a progressive tendency they, the designers, tend to rely more and more on digitizing their vision and mission, which subsequently give them, impressive and expressive superiority, that would influence the users conscious on the one hand and manipulate their subconscious on the other. Within that process designers work hard to break any mental firewall that would prevent their ideas from pervading the space of any mental environment the user, build or visualize. In that context, to what extent such ways of mental entertainments used by architects, legitimize deception in design? What distinguishes employing the rhythmic simulation of the narrative fictional inceptions (virtual reality) from deploying the adaptive stimulation of the experience modeling conceptions. The difference between planting an idea and constructing an idea. It is not the intention of the paper to prove the failure of the computer aided design neither to stand against the digital architectural design media and applications development. It is rather to present a different way of understanding of how architectural design whether virtual, digital, or real can stimulates and induces codes and messages that is correlated to the brainwave cognitive attributes and can generate a narrative brain environment where the brain can construct and simulate its own fictional design. Doing so, the paper will review certain experimental architectural events and activities which integrate sound and sight elements and effects within some electronic, technical and digital environments.

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.
