title	Biomimetic Robotic Construction Process - An approach for adapting mass irregular-shaped natural materials

summary	Beaver dams are formed by two main processes. One is that beavers select proper woods for constructing. The other one is that streams aggregate those woods to be assembled. Using this approach to construction structure is suitable for natural environment. In this paper, we attempt to develop a construction process which is suitable for all-terrain construction robot in the future. This construction process is inspired by beavers' construction behavior in nature. Beavers select proper sticks to make the structure stable. We predict that particular properties of sticks contribute gravity-driven assembly of wood structure. Thus, we implement the system with machine learning to find proper properties of sticks to improve selection mechanism of construction process. During this construction process, 3D scanner on robotic arm scans and recognizes sticks on terrain, and then robot will select proper sticks and place them. After placement, the system will scan and record the results for learning mechanism.

title	Material computation—4D timber construction: Towards building-scale hygroscopic actuated, self-constructing timber surfaces
source	International Journal of Architectural Computing vol. 14 - no. 1, 49-62
summary	The implementation of active and responsive materials in architecture and construction allows for the replacement of digitally controlled mechanisms with material-based systems that can be designed and programmed with the capacity to compute and execute a behavioral response. The programming of such systems with increasingly specific response requires a material-driven computational design and fabrication strategy. This research presents techniques and technologies for significantly upscaling hygroscopically actuated timber-based systems for use as self-constructing building surfaces. The timber’s integrated hygroscopic characteristics combined with computational design techniques and existing digital fabrication methods allow for a designed processing and reassembly of discrete wood elements into large-scale multi element bilayer surfaces. This material assembly methodology enables the design and control of the encoded direction and magnitude of humidity-actuated responsive curvature at an expanded scale. Design, simulation, and material assembly tests are presented together with formal and functional configurations that incorporate self-constructing and self-rigidizing surface strategies. The presented research and prototypes initiate a shift toward a large-scale, self-construction methodology.

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	Robotic Forming: Rapidly Generating 3D Forms and Structures through Incremental Forming

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. 539-548
summary	The past years have seen significant developments in the area of robotic design interfaces. Building upon visual programming environments, these interfaces now allow the creative industry to de- fine even complex fabrication processes in an easy, accessible way, while providing instant, production-immanent feedback. However, while these software tools greatly speed up the programming of robot- ic arms, many processes are still inherently slow: Subtractive process- es need to remove a large amount of material with comparably small tools, while additive processes are limited by the speed of the extruder and the properties of the extruded material. In this research we present a new method for incrementally shaping transparent polymer materi- als with a robotic arm, without requiring heat or dies for deep- drawing, thus allowing us to rapidly fabricate individual panels within a minimum of time.

title	Building Traditions with Digital Research - Reviewing the Brick Architecture of Raúl Hestnes Ferreira through Robotic Fabrication
doi	https://doi.org/10.52842/conf.ecaade.2016.1.123

summary	Brick construction has a strong tectonic tradition in architecture, being used both as a structural and as an expressive material. Despite several technological innovations at the composition and production level, its application still relies on talented craftsmanship, which has some natural human limitations and has becoming harder to find in the present days. To overcome this problem, robotic assembly technologies have been introduced in the field, opening new design and construction possibilities. In this context, this paper intends to examine their application but from a different perspective, by examining how they can be used to connect with the traditions in brick construction. To do so, it presents and analyses the work of Portuguese architect Raúl Hestnes Ferreira, and develops a computational design and robotic fabrication research on the topics of corner, column and dome bricks. The production of a column design at the 1:1 scale using an automated process serves to reflect on the relevance of new technologies to innovate in accordance to tradition.

title	Discrete Assembly and Digital Materials in Architecture
doi	https://doi.org/10.52842/conf.ecaade.2016.1.143
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. 143-151
summary	The paper will discuss two projects which explore the territory of discrete or digital material organisations in an architectural context. Taking inspiration from the field of Digital Materials, this paper presents an approach to architectural design which is fundamentally "digital" - not just in the process but also in its physical organisation. The use of discrete and digital materials in architecture is argued for from both an architectonic point of view, as well as from efficiencies related to automation of construction. Experiments with robotic assembly are caught between on the one hand the desire to increase speed, and on the other hand increased complexity. This paper argues that robotic assembly on the scale of architecture is only feasible and scalable in the context of digital materials and discrete computation, which has a limited set of connectivity problems. The two projects are a first attempt to translate the concept of Digital Materials to the domain of architecture. The result is an architecture which is digital in its physical organisation. It demonstrates how differentiated, complex and heterogeneous spaces can be achieved with just serialised, discrete elements.

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
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. 224-233
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	Due to climate change and the problematic amount of waste and CO2 emissions in the construction industry, non-human organisms and sustainable solutions are key motivators of the study. This paper focuses on developing a bioreceptive (Guillitte, 1995) composite suitable for additive manufacturing, composed to support growth of various organisms. It investigates key properties which have shown to be beneficial for promoting biological growth, such as water absorption, water permeability, humidity, and surface texture. The study evaluates the effect of two groups of clay-based waste additives, wooden sawdust (Arslan, et al., 2021) and sediment material sourced from local tunnel excavation in Prague. Simultaneously the need for intelligent reintegration and waste use is prevalent. Additive fabrication offers the ability to test a variety of composites and (re-)integrate them into the manufacturing processes. Current approach explores how to design artificial environments/skins for greenery and small life with the potential to improve both diversity and survivability while maintaining a better climate in its immediate surroundings. Bioreceptive design has the potential to improve the quality of the urban environment and bring new aesthetic influences into it (Cruz and Beckett 2016, p. 51-64).

title	rolyPOLY - A Hybrid Prototype for Digital Techniques and Analog Craft in Architecture
doi	https://doi.org/10.52842/conf.ecaade.2016.1.631

summary	The rapid emergence of computational design tools, advanced material systems and robotic fabrication within the disciplines of architecture and construction has granted designers immense freedom in form and assembly, while retaining pronounced control over output quality throughout the entirety of the design and fabrication process. Simultaneously, the complexity inherent within these tools and processes can lead to a loss of craft though the production of methodologies, forms and artifacts left with extremely recognizable residues from tooling processes utilized during their production. This paper investigates the fecund intersection of digital technologies and handcraft through core-less carbon fiber reinforced polymer (CFRP) winding as a means of creating a new typology of digital craft blurring the line between human and machine. Through the lens of an innovative wound CFRP shelter rolyPOLY completed during the winter of 2015, this paper will show the exigencies and affordances between the realms of digital and analog methodologies of CFRP winding on large-scale structures.

title	Growth Based Fabrication Techniques for Bacterial Cellulose: Three-Dimensional Grown Membranes and Scaffolding Design for Biological Polymers
doi	https://doi.org/10.52842/conf.acadia.2016.488
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. 488-495
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 attempts to demonstrate a seamless transformable material system through an interdependent designed assembly of two materials with different material properties (anisotropic knit textile and isotropic silicone) but similar behaviors (stretch). The transformable system is achieved by balancing the volumetric expansion through a silicone tube, under inflation, with the controlled resistance to stretch by a custom knit fabric. The use of a CNC knitting machine allows not only an opportunity to program the stretch behavior of a knit fabric, by controlling the amount of yarn material to be deposited, but also an ability to knit multiple layers of fabric simultaneously, in order to create a space capable of accommodating an external element seamlessly. The paper will showcase a series of experiments ranging from the initial search for compatible material combinations to the varied structures of the tube sleeve and its relationship with surrounding region. The final prototype attempts to utilize the various behavioral properties of the material system learned from the experiments to create a transformable three-dimensional structure.

title	Teaching Parametric Design in Architecture - A Case Study

summary	The increasing technological advancements nowadays make the integration of digital tools and techniques in architecture pedagogy a must. A course in the department of architecture at Birzeit University in Palestine was proposed as a summer course in order to introduce students to the possibilities of using digital parametric tools and techniques in architecture design and manufacturing. In reflection of the experiment of the course, in which students were asked to design and construct a temporary pavilion, the paper will examine the potentials and challenges of using parametric digital tools in architecture design, and the way students imagine and conceive the performance of their design ideas virtually and practically. Furthermore, the project proposes that form is not constrained to the form-making process, but form must be a response to a material system and its properties, and thus material should be engaged in the design process. Initial design ideas are explored by building a parametric 3D digital model using a visual scripting platform. This virtual model allows for the evaluation of the performance of the design and the assembly method before realization and, moreover, experiments with design alternatives and forms. The final full-detailed digital model will be used in the fabrication phase to construct a one-to-one scale physical model in the real world, which gives students the chance to get sense and interact with the implemented environment and to experience their designs in real world.

title	An environmental perspective on digital fabrication in architecture and construction
doi	https://doi.org/10.52842/conf.caadria.2016.797
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. 797-806
summary	Digital fabrication processes and technologies are becom- ing an essential part of the modern product manufacturing. As the use of 3D printing grows, potential applications into large scale processes are emerging. The combined methods of computational design and robotic fabrication have demonstrated potential to expand architectur- al design. However, factors such as material use, energy demands, du- rability, GHG emissions and waste production must be recognized as the priorities over the entire life of any architectural project. Given the recent developments at architecture scale, this study aims to investi- gate the environmental consequences and opportunities of digital fab- rication in construction. This paper presents two case studies of classic building elements digitally fabricated. In each case study, the projects were assessed according to the Life Cycle Assessment (LCA) frame- work and compared with conventional construction with similar func- tion. The analysis highlighted the importance of material-efficient de- sign to achieve high environmental benefits in digitally fabricated architecture. The knowledge established in this research should be di- rected to the development of guidelines that help designers to make more sustainable choices in the implementation of digital fabrication in architecture and construction.

title	Reality is interface: Two motion capture case studies of human–machine collaboration in high-skill domains
source	International Journal of Architectural Computing vol. 14 - no. 4, 398-408
summary	This article explores hybrid digital/physical workflows in the building trades, a high-skill domain where human dexterity and craft can be augmented by the precision and repeatability of digital design and fabrication tools. In particular, the article highlights two projects where historic construction techniques were extended through live motion capture of human gesture, information-rich visualization projected in the space of fabrication and custom robotic tooling to generate free-form running moulds. The first case study explores decorative plastering techniques and an augmented workflow where designers and craftspeople can quickly explore patterns through freehand sketch, test ideas with shaded previews and seamlessly produce physical parts using robotic collaborators. The second case study reimagines a roman vaulting technique that used terracotta bottles as part of an interlocking masonry system. Motion capture is used to place building elements precisely in material arrays with real-time visual feedback guiding the hand-held placement of each bottle. These case studies serve to underscore the emerging importance of reality capture in the design and construction of the built environment. Increasingly, the algorithmic power of computational tools and the nuances of human skill can be combined in hybrid design and fabrication workflows.

summary	This paper investigates the potential of behavioral construction strategies for architectural production through the design and robotic fabrication of three-dimensional woven structures inspired by the behavioral fabrication logic used by the weaverbird during the construction of its nest. Initial research development led to the design of an adaptive robotic fabrication framework composed of an online agent-based system, a custom weaving end-effector and a coordinated sensing strategy utilizing 3D scanning.The outcome of the behavioral weaving process could not be predetermined a priori in a digital model, but rather emerged out of the negotiation among design intentions, fabrication constraints, performance criteria, material behaviors and specific site conditions. The key components of the system and their role in the fabrication process are presented both theoretically and technically, while the project serves as a case study of a robotic production method envisioned as a soft system: a flexible and adaptable framework in which the moment of design unfolds simultaneously with fabrication, informed by a constant flow of sensory information.

summary	Each year, the United States discards 375 million tons of concrete construction debris to landfills (U.S. EPA 2016), but this is a new paradigm. Past civilizations cannibalized their constructions to produce new architectures (Hopkins 2005). This paper interrogates one cannibalistic methodology from the past known as cyclopean masonry in order to translate this valuable method into a contemporary digital procedure. The work contextualizes the techniques of this method and situates them into procedural recipes which can be applied in contemporary construction. A full-scale prototype is produced utilizing the described method; demolition debris is gathered, scanned, and processed through an algorithmic workflow. Each rubble unit is then minimally carved by a robotic arm and set to compose a new architecture from discarded rubble debris. The prototype merges ancient construction thinking with digital design and fabrication methodologies. It poses material cannibalism as a means of combating excessive construction waste generation.

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.

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

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.
