title	Printing Compound-Curved Sandwich Structures with Robotic Multi-Bias Additive Manufacturing
source	Proceedings of the 2023 DigitalFUTURES The 5st International Conference on Computational Design and Robotic Fabrication (CDRF 2023)
doi	https://doi.org/https://doi.org/10.1007/978-981-99-8405-3_44
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.

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.

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

summary	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.

title	Time in Adaptable Architecture - Deployable emergency intelligent membrane
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. 249-258
summary	The term "Parametricism" widespread mainly by Patrick Schumacher (Schumacher, 2008) is worthy of study. Developing the concept of Human Oriented Parametric Architecture, the need of implementing time as the lost parameter in current adaptive design techniques will be discussed. Morphogenetic processes ideas will be discussed through the principle of an adaptable membrane as a case study. A model implementing a unique Arduino[i] on the façade will control its patterns performance through an Artificial Neural Network that will understand the kind of scenario the building is in, activating a Genetic Algorithm that will optimize the insulation performance of the ETFE pillows. The system will work with a global behavior for façade pattern performance and with a local one for each pillow, giving the option of individual sun-shading control. Machine learning implementation will give the façade the possibility to learn from the efficacy of its decisions through time, eliminating the need of a general on-off behavior.

title	Geospatial Tool Evaluating Job Location Mismatch, Based on Available Workforce and Transit Options - Evaluating property location in a city using large-scale datasets
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. 557-566
summary	The paper addresses the issue of spatial mismatch of jobs and the accessibility to job locations based on different age, income and industry group. Taking Atlanta as a case study, we developed a geospatial analysis tool enabling developers, the city planning bureau and the residents to identify potential sites of redevelopment with better economic development opportunities. It also aids to find potential location to live with respect to user’s choices for transit options, walkability, job location and proximity to chosen land use. We built our model on a block level in the city, imparting them a score, visualizing the data as a heat map. The metrics to compute the score included proximity to job, proximity to worker’s residence, transit availability, walkability and number of landmark elements near the site. We worked with Longitudinal Employer-Household Dynamics (LEHD) Data along with residence area characteristics (RAC) and work place area characteristic (WAC) data sets, where the total number of data-points was over 3 million. It was challenging for us to optimize computation such that the prototype performs statistical analysis and updates visualization in real time. The research further is prototyped as a web application leveraging Leaflet’s Open Street Maps API and D3 visualization plugin. The research showed that there is a high degree of spatial mismatch between home and job locations with very few jobs with driving distance within 5 -10 miles with limited transit options in Atlanta. Further, it showed that low-earning workers need to travel significantly larger distance for work compared to higher class.

title	Use of a Low-Cost Humanoid for Tiling as a Study in On-Site Fabrication: Techniques and Methods
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
doi	https://doi.org/10.52842/conf.acadia.2016.214
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	Development of Kinetic Facade Units with BIM-Based Active Control System for the Adaptive Building Energy Performance Service
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. 517-526
doi	https://doi.org/10.52842/conf.caadria.2016.517
summary	This paper proposes a novel concept and practice to engage the BIM model as a control system of building energy performance service. This issue can be divided into two sub-issues including the development of more eco-friendly fac?ade which can interact with its local environment, and the related active control system which can process the environmental parameters for eco-friendly actions. This research designs the Parametric Adaptive Skin System (PASS) to en- gage the adaption of natural sunlight use for higher building perfor- mance. PASS consists of kinetic fac?ade components dominated by the BIM-based parametric engine called Dynamo. The PASS prototype demonstrates that the workflows is successful in using a real light sen- sor plus simulated solar terms to drive the interaction of virtual Revit model and physical PASS model.

title	Parametricism vs Materialism - Evolution of digital technologies for development
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, 597 p.
summary	We build on previous technological developments in CAAD by looking into parametric design exploration and the development of the concept of parametricism. We use the phenomenological backdrop to account for our physical experiences and encounters as well as our mental ones; both evident in the link between parametric design as a process and an outcome. In specific, we previously examined two particular metaphors. The first metaphor addressed aspects of virtual environments that resemble our physical world; In other words, computer model as physical model and digital world as material world. In this volume, we extend the exploration into aspects of virtual environments and their resemblance to physical environments by looking at ‘performance’ aspects: the way in which environments are sensed, measured, tracked and visualised. Moreover, we reflect on matters and materiality in both virtual and physical space philosophically, theoretically, practically and reflectively. The second metaphor looked into the modes and means of interaction between our bodies and such virtual environment. Here we extend the investigation to look at the ways in which measures of environmental performance influence human interaction in real environments. The exploration takes us further to look into the area of design fabrication of the built environment, and methods in which developed processes meet environmental performance requirements, and the innovative outcomes that lead to disruptive technologies getting introduced into design and we revisit parametric design under this focus area.

title	Multiflight - Creating Interactive Stairs through Positive Technology
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. 295-308
summary	This paper details a pedagogical project which calls for an improved design performance of the existing built environment through the use of smart technology and data-driven design. The project is an investigation into ways in which to improve the performance of a ‘pre-selected university building’ through the use of a media facade that allows for interactive experiences. Existing problems of the selected building have been identified through observation and research using a rich picture and agile approach. An underutilised staircase was selected as the focus site for a series of computational design and interactive design studies. The brief of this mini-research project aims to encourage more people to use the stairs and create a memorable experience with a technological approach through the application of a site specific interactive media installation. The project is an interactive staircase which utilises LED strips and generative sound. The project features a series of light boxes which are connected to the existing staircase balustrade. Arduino, passive infra-red sensors, and other motion detection sensors were used to allow for light and generative sound interaction with users using visual scripting tools and a generative design platform. Sensing technology was used as a real-time data-gathering device during the site analysis phase as well as an input device for the designed prototype to allow the testing of the data-driven design. This paper details the study and resultant interactive prototypes. It also discusses the exploration of performance based design ideas into design workflows and the integration of sensing tools into the design process. It concludes by identifying possible implications on using the Internet of Things concepts to facilitate the design of interactive architecture.

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

title	Hybrid Sentient Canopy: An implementation and visualization of proprioreceptive curiosity-based machine learning
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. 362-371
doi	https://doi.org/10.52842/conf.acadia.2016.362
summary	This paper describes the development of a sentient canopy that interacts with human visitors by using its own internal motivation. Modular curiosity-based machine learning behaviour is supported by a highly distributed system of microprocessor hardware integrated within interlinked cellular arrays of sound, light, kinetic actuators and proprioreceptive sensors in a resilient physical scaffolding system. The curiosity-based system involves exploration by employing an expert system composed of archives of information from preceding behaviours, calculating potential behaviours together with locations and applications, executing behaviour and comparing result to prediction. Prototype architectural structures entitled Sentient Canopy and Sentient Chamber developed during 2015 and 2016 were developed to support this interactive behaviour, integrating new communications protocols and firmware, and a hybrid proprioreceptive system that configured new electronics with sound, light, and motion sensing capable of internal machine sensing and externally- oriented sensing for human interaction. Proprioreception was implemented by producing custom electronics serving photoresistors, pitch-sensing microphones, and accelerometers for motion and position, coupled to sound, light and motion-based actuators and additional infrared sensors designed for sensing of human gestures. This configuration provided the machine system with the ability to calculate and detect real-time behaviour and to compare this to models of behaviour predicted within scripted routines. Testbeds located at the Living Architecture Systems Group/Philip Beesley Architect Inc. (LASG/PBAI, Waterloo/Toronto), Centre for Information Technology (CITA, Copenhagen) National Academy of Sciences (NAS) in Washington DC are illustrated.

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	Design with bamboo bend: Bridging natural material and computational design
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. 125-133

summary	Bamboo is a high potential alternative solution for substi- tuting industrial material with its natural characteristics, economical and environmental aspects. However, one of the biggest challenges for natural materials to be used in computational designed is the control- lability due to its unevenness nature. The other gap is the lack of ma- terial parameters that might be bridged by analysing data acquired from conventional tests. This research studied the raw bamboo strip and its natural forming from bending, by using sampling points and curvature reconstruction. The parametric models of bamboo strips were then constructed to represent its material behaviours for form prediction, material selection, and simulation in parametric design. It also serves as an assistive method for material selection when crafting with bamboo bend.

title	Protocol of Error: The design and construction of a bending-active gridshell from natural bamboo
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. 415-424
doi	https://doi.org/10.52842/conf.caadria.2016.415
summary	This paper advocates alternative methods to overcome the impossibility of realising ‘perfect’ digital designs. It discusses Hong Kong’s 2015 ‘ZCB Bamboo Pavilion’ as a methodological case study for the design and construction of architecture from unprocessed natu- ral bamboo. The paper critically evaluates protocols set up to deal with errors resulting from precise digital design systems merging with inconsistent natural resources and onsite craftsmanship. The paper starts with the geometric and tectonic description of the project, illus- trating a complex and restrictive construction context. Bamboo’s unique growth pattern, structural build-up and suitability as a bending- active material are discussed and Cantonese bamboo scaffolding craftsmanship is addressed as a starting point for the project. The pa- per covers protocols, construction drawings and assembly methods developed to allow for the incorporation and of large building toler- ances and dimensional variation of bamboo. The final as-built 3d scanned structure is compared with the original digital model. The pa- per concludes by discussing the necessity of computational architec- tural design to proactively operate within a field of real-world inde- terminacy, to focus on the development of protocols that deal with imperfections, and to redirect design from the virtual world towards the latent opportunities of the physical.

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

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	Formeta:3D is a project that engages the posthuman through the development of a machine that translates inputs from its surroundings into physical form in real-time. By responding to interaction with the inhabitants of its environs and incorporating the detected activity in the inflections of the produced form, it has an impact on the activity in the space, resulting in a recursive feedback loop that incorporates the digital, the physical, and the experiential. This paper presents the development of this project in detail, providing a methodology and toolchain for implementing real-time interaction with additive physical form derived from digital inputs and examining the results of an interactive installation set up to test the implementation.
