title	Tactile narratives about an architecture’s ornaments
source	SIGraDi 2017 [Proceedings of the 21th Conference of the Iberoamerican Society of Digital Graphics - ISBN: 978-956-227-439-5] Chile, Concepción 22 - 24 November 2017, pp.479-485
summary	This study experiments a process of production of tactile representations of architectural elements of a nineteenth century mansion, house to a university museum: Museu do Doce, Pelotas, RS. The Museum uses the concept of Universal Design to guide its direct and/or mediated communication solutions. The house is distinguished by ceilings of ornamental stuccoes, evidently perceived only by the sense of sight. To describe them, a set of representations is being produced, using 3D scanning and digital fabrication technologies, using formal decomposition, and different scales, to construct a narrative to be understood by touching.

title	Analogue Automation - The Gateway Pavilion for Headland Sculpture on the Gulf

summary	The Waiheke Gateway Pavilion, designed by Stevens Lawson Architects originally for the 2010 New Zealand Venice Biennale Pavilion, was brought to fruition for the 2017 Headland Sculpture on the Gulf Sculpture trail by students from Unitec Institute of Technology. The cross disciplinary team comprised of students from architecture and construction disciplines working in conjunction with a team of industry professionals including architects, engineers, construction managers, project managers, and lecturers to bring the designed structure, an irregular spiral shape, to completion. The structure is made up of 261 unique glulam beams, to be digitally cut using computer numerical control (CNC) process. However, due to a malfunction with the institutions in-house CNC machine, an alternative hand-cut workflow approach had to be pursued requiring integration of both digital and analogue construction methods. The digitally encoded data was extracted and transferred into shop drawings and assembly diagrams for the fabrication and construction stages of design. Accessibility to the original 3D modelling software was always needed during the construction stages to provide clarity to the copious amounts of information that was transferred into print paper form. Although this design to fabrication project was challenging, the outcome was received as a triumph amongst the architecture community.

summary	Please write your aToday, in a moment when digital technologies are taking command of many architectural design and construction processes, it is important to examine the place and role of traditional ones. Designed by Álvaro Siza and Eduardo Souto de Moura in collaboration with Cecil Balmond, the Serpentine Gallery Pavilion 2005 reflects the potential of combining those two different approaches in the production of innovative buildings. For inquiring this argument, this paper investigates the development of this project from its conception to construction with a double goal: to uncover the relationship between analogical and digital processes, and to understand the architects' role in a geographically distributed workflow, which involved the use of computational design and robotic fabrication technologies. To support this examination, the authors designed and fabricated a 1:3 scale prototype of part of the Pavilion, which also served to check and reflect on the technological evolution since then, which is setting different conditions for design development and collaboration.bstract here by clicking this paragraph.

title	A Multisensory Computational Model for Human-Machine Making and Learning
doi	https://doi.org/10.52842/conf.acadia.2017.238
source	ACADIA 2017: DISCIPLINES & DISRUPTION [Proceedings of the 37th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-96506-1] Cambridge, MA 2-4 November, 2017), pp. 238-247
summary	Despite the advancement of digital design and fabrication technologies, design practices still follow Alberti’s hylomorphic model of separating the design phase from the construction phase. This separation hinders creativity and flexibility in reacting to surprises that may arise during the construction phase. These surprises often come as a result of a mismatch between the sophistication allowed by the digital technologies and the designer’s experience using them. These technologies and expertise depend on one human sense, vision, ignoring other senses that could be shaped and used in design and learning. Moreover, pedagogical approaches in the design studio have not yet fully integrated digital technologies as design companions; rather, they have been used primarily as tools for representation and materialization. This research introduces a multisensory computational model for human-machine making and learning. The model is based on a recursive process of embodied, situated, multisensory interaction between the learner, the machines and the thing-in-the-making. This approach depends heavily on computational making, abstracting, and describing the making process. To demonstrate its effectiveness, I present a case study from a course I taught at MIT in which students built full-scale, lightweight structures with embedded electronics. This model creates a loop between design and construction that develops students’ sensory experience and spatial reasoning skills while at the same time enabling them to use digital technologies as design companions. The paper shows that making can be used to teach design while enabling the students to make judgments on their own and to improvise.

title	Robot-Aided Fabrication of Interwoven Reinforced Concrete Structures
source	Gülen Çagdas, Mine Özkar, Leman F. Gül and Ethem Gürer (Eds.) Future Trajectories of Computation in Design [17th International Conference, CAAD Futures 2017, Proceedings / ISBN 978-975-561-482-3] Istanbul, Turkey, July 12-14, 2017, p. 457.
summary	This paper focuses on the realization of three-dimensionally interwoven concrete structures and their design process. The output is part of an ongoing research in developing an innovative strategy for the use of robotics in construction. The robotic fabrication techniques described in this paper are coupled with the computational methods dealing with geometry rationalization and material constraints among others. By revisiting the traditional bar bending techniques, this research aims to develop a novel approach by the reduction of mechanical parts for retaining control over the desired geometrical output. This is achieved by devising a robotic tool-path, developed in KUKA\|prc with Python scripting, where fundamental material properties, including tolerances and spring-back values, are integrated in the bending motion methods via a series of mathematical calculations in accord with physical tests. This research serves to demonstrate that robotic integration while efficient in manufacturing it also retains valid alignment with the architectural design sensibility.

summary	There has been significant research into large-scale 3D printing processes with industrial robots. These were initially used to extrude in a layered manner. In recent years, research has aimed to make use of six degrees of freedom instead of three. These so called "spatial extrusion" methods are based on a toolhead, mounted on a robot arm, that extrudes a material along a non horizontal spatial vector. This method is more time efficient but up to now has suffered from a number of limiting geometrical and structural constraints. This limited the formal possibilities to highly repetitive truss-like patterns. This paper presents a generalised approach to spatial extrusion based on the notion of discreteness. It explores how discrete computational design methods offer increased control over the organisation of toolpaths, without compromising design intent while maintaining structural integrity. The research argues that, compared to continuous methods, discrete methods are easier to prototype, compute and manufacture. A discrete approach to spatial printing uses a single toolpath fragment as basic unit for computation. This paper will describe a method based on a voxel space. The voxel contains geometrical information, toolpath fragments, that is subsequently assembled into a continuous, kilometers long path. The path can be designed in response to different criteria, such as structural performance, material behaviour or aesthetics. This approach is similar to the design of meta-materials - synthetic composite materials with a programmed performance that is not found in natural materials. Formal differentiation and structural performance is achieved, not through continuous variation, but through the recombination of discrete toolpath fragments. Combining voxel-based modelling with notions of meta-materials and discrete design opens this domain to large-scale 3D printing. Please write your abstract here by clicking this paragraph.

summary	Most recent developments in the design of free form shells pursue new approaches in digital fabrication based on material properties and construction-aware design. In this research we proposed an alternative approach based on implementation of expanded polystyrene (EPS), a non-standard material for shells, in the process of industrial robot fabrication that enables fast and precise cutting of building elements. Main motivation for using EPS as a building material was driven by numerous advantages when compared to commonly used materials such as: recycleability, cost-efficiency, high earthquake resistance, durability and short assembly time. We describe case specific fabrication approach based on numerous production constraints (size of the panels, limited robot workspace, in situ conditions) that directly design the process.

summary	In this research, we explore the implementation of panels with a single bending direction as cylindrical surfaces; in so doing, we present our ongoing research, focusing on finding ways to simply and affordably address the problem of constructability of double-curved structures. By encoding 3D freeform surface information into a 2D workflow, our in-house software (named UNFOLDING) breaks down complex mesh structures into a number of discrete and flat quadrilaterals that can be translated into a fabrication layout. UNFOLDING provides a practical way of linking the process of production and assembly to freeform architectural design. After introducing UNFOLDING in two design studios at Texas A&M University, freshman architecture students used laser-cut quadrilateral panels to design and construct several complex forms with positive or negative Gaussian curvatures.

title	Investigations in robotic-assisted design: Strategies for symbiotic agencies in material-directed generative design processes
source	International Journal of Architectural Computing vol. 15 - no. 1, 70-86
summary	The research described in this article utilises a phase-changing material, three-dimensional scanning technologies and a six-axis industrial robotic arms as vehicles to enable a novel framework where robotic technology is utilised as an ‘amplifier’ of the design process to realise geometries that derive from both constructive visions and architectural visions through iterative feedback loops between them. The robot in this scenario is not a fabrication tool but the enabler of an environment where the material, robotic and human agencies interact. This article describes the exploratory research for the development of a dialogic design process, sets the framework for its implementation, carries out an evaluation based on designer use and concludes with a set of observations. One of the main findings of this article is that a deeper collaboration that acknowledges the potential of these tools, in a learning-by-design method, can lead to new choreographies for architectural design and fabrication.

title	Ivy: Progress in Developing Practical Applications for a Weighted-Mesh Representation for Use in Generative Architectural Design
doi	https://doi.org/10.52842/conf.acadia.2017.446
source	ACADIA 2017: DISCIPLINES & DISRUPTION [Proceedings of the 37th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-96506-1] Cambridge, MA 2-4 November, 2017), pp. 446- 455
summary	This paper presents progress in the development of practical applications for graph representations of meshes for a variety of problems relevant to generative architectural design (GAD). In previous work (Nejur and Steinfeld 2016), the authors demonstrated that while approaches to marrying mesh and graph representations drawn from computer graphics (CG) can be effective within the domains of applications for which they have been developed, they have not adequately addressed wider classes of problems in GAD. There, the authors asserted that a generalized framework for working with graph representations of meshes can effectively bring recent advances in mesh segmentation to bear on GAD problems, a utility demonstrated through the development of a plug-in for the visual programming environment Grasshopper. Here, we describe a number of implemented solutions to mesh segmentation and transformation problems, articulated as a series of additional features developed as a part of this same software. Included are problems of mesh segmentation approached through the creation of acyclic connected graphs (trees); problems of mesh transformations, such as those that unfold a segmented mesh in anticipation of fabrication; and problems of geometry generation in relation to a segmented mesh, as demonstrated through a generalized approach to mesh weaving. We present these features in the context of their potential applications in GAD and provide a limited set of examples for their use.

title	A Robotic Fabrication Methodology for Dovetail and Finger Jointing: An Accessible & Bespoke Digital Fabrication Process for Robotically-Milled Dovetail & Finger Joints
doi	https://doi.org/10.52842/conf.acadia.2017.456
source	ACADIA 2017: DISCIPLINES & DISRUPTION [Proceedings of the 37th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-96506-1] Cambridge, MA 2-4 November, 2017), pp. 456- 463
summary	Since the advent of industrialized processes in modern construction industries, the development of and relationship between computer-aided tools of design and computer-controlled tools of fabrication has steadily yielded new and innovative construction methodologies. Whilst industry has adopted many of these innovations for use by highly efficient machines and flexible processes, their operation is often highly dependent on industrial scales of production, and thus often inaccessible for small-scale, bespoke and affordable application. The prototype integrated joint milling methodology, case study and open-source software plugin ‘Dove’ presented in this paper, explores the efficacy of algorithmic processes in dynamically generating complex tooling paths and machine code for fabrication of bespoke dovetail and finger joints on a 6-axis industrial robot. The versatility, speed and precision of 6-axis robotic milling, allows us to liberate the efficiency, integrity and aesthetic of the dovetail and finger joint types from traditional application, and apply them to new architectures involving mass-customisation, complex form, and diverse materialities. In the development of full-immersion milling toolpaths and back-face filleting techniques that drastically reduce cutting times, tool path complexity and material waste, this study seeks to build upon past and current research by proposing a comparatively simple, efficient and more intuitive approach to robotically-fabricated integrated jointing for application at a variety of scales.

summary	The paper explores the use of in-house developed self-reconfigurable modular robotic system in civil construction activities and investigates a concept where an arbitrary Civil Engineering structure or a daily use industrial product are self-assembled from a number of self-reconfigurable composite blocks. The system extends current range of modular robot systems (mDrs) where autonomous modules self-assemble into a wide variety of forms. However, contrary to conventional mDrs, MoleMOD has not mechatronic actuating parts permanently fixed to each individual module. The MoleMOD actuators are separable and operate inside the modules, tight them together or relocate them to required configuration. It significantly reduces number of expensive mechatronics parts and the environment the actuators operate. Although MoleMOD focuses on architecture, it can take over other mDrs tasks as research and rescue. This paper describes properties, advantages, foreseen applications, and basic design specifications of the second generation prototype.

summary	This paper proposes a design and fabrication approach based on the conceptualization of architectural formations as spatial assemblies of discrete building blocks to be aggregated through custom robotic procedures. Such strategy attempts to create synergies between different technological methods and to define a new and open design space where discrete design, serial prototyping and robotic assembly can be exploited to create complex reconfigurable structures. With the aim to allow users to explore the field of discrete geometries for architectural application without need for prior programming knowledge, we developed a software framework for representing and designing with discrete elements, different digital fabrication techniques integrated with conventional production processes for serial prototyping of repetitive units, and custom robotic fabrication routines, allowing a direct translation from aggregated geometry to assembly toolpath. Together these methods aim at creating a more direct connection between design and fabrication, relying on the idea of discrete elements assembly and on the parallel between modular design and modularized robot code generation.

Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 220-225.
summary	Previous research projects (Adel, Agustynowicz, and Wehrle 2021; Adel Ahmadian 2020; Craney and Adel 2020; Adel et al. 2018; Apolinarska et al. 2016; Helm et al. 2017; Willmann et al. 2015; Oesterle 2009) have explored the use of comprehensive digital design-to-fabrication workflows for the construction of nonstandard timber structures employing robotic assembly technologies. More recently, the Robotically Fabricated Structure (RFS), a bespoke outdoor timber pavilion, demonstrated the potential for highly articulated timber architecture using short timber elements and human-robot collaborative assembly (HRCA) (Adel 2022). In the developed HRCA process, a human operator and a human fabricator work alongside industrial robotic arms in a shared working environment, enabling collaborative fabrication approaches. Building upon this research, we present an exploration adapting HRCA to nail-laminated timber (NLT) fabrication, demonstrated through a case study exhibition (Figures 1 and 2).

title	Robotic Formwork in the MARS Pavilion: Towards The Creation Of Programmable Matter
doi	https://doi.org/10.52842/conf.acadia.2017.522

summary	The proliferation of parametric tools has allowed for the design of previously impossible geometry, but the construction industry has failed to keep pace. We demonstrate the use of industrial robots to disrupt the ancient process of casting concrete and create an adjustable formwork capable of generating various cast components based on digital input, crafting a new approach to “programmable matter.” The resulting research delineates a novel methodology to facilitate otherwise cost-prohibitive, even impossible design. The MARS Pavilion employs this methodology in a building-sized proof of concept where manipulating fabric with industrial robots achieves previously unattainable precision while casting numerous connective concrete components to form a demountable lattice structure. The pavilion is the result of parametric form finding, in which a catenary structure ensures that the loads are acting primarily in compression. Every concrete component is unique, yet can be assembled together with a 1/16-inch tolerance. Expanding Culver & Sarafian’s previous investigations, industrial robot arms are sent coordinates to position fabric sleeves into which concrete is poured, facilitating a rapid digital-to-physical casting process. With this fabrication method, parametric variation in design is cost-competitive relative to other iterative casting techniques. This digital breakthrough necessitated analogue material studies of rapid-setting, high-strength concrete and flexible, integral reinforcing systems. The uniquely shaped components are coupled with uniform connectors designed to attach three limbs of concrete, forming a highly stable, compressive hex-grid shell structure. A finite element analysis (FEA) was a critical step in the structural engineering process to simulate various load scenarios on the pavilion and drive the shape of the connective elements to their optimal form.

summary	In this research, we present a system to allow designers to adaptively control an industrial robot from within a 3D modeling environment, for the purpose of real time feedback with respect to visual imagery of the object as well as robot pose during the fabrication process. Our work uses the Kuka industrial robots due to their capability in fabrication and programmability, and the Rhino 3D modeling software with the Grasshopper plugin which allows for visual programming for designers. A Microsoft Kinect sensor is used to provide visual feedback of the part during the fabrication process. We present the methodology used to develop the system, explaining various design and architecture choices made to allow for easy use of our system, while ensuring our system is open to further extension. We also show qualitative results of the fabrication process performed using our system in order to validate that our proposed system improves the interaction and collaboration between designer and robot when performing the task, in contrast to the iterative process that is generally followed.

title	A Generalized Approach to Non-Layered Fused Filament Fabrication

summary	This research attempts to generalize an approach for large-scale, non-layered spatial extrusion. The methodology consists of splitting a volume, representing any arbitrary geometry, into discrete fragments with a finite number of possible arrangements. These fragments are combined in response to a series of design criteria. A novel application of graph theory algorithms is used to generate a continuous and non-overlapping path through the discrete segments. Physical and mechanical issues related to extrusion technology are explored. The computational model takes into consideration the grade and limitations of different kinds of equipment and material properties to counteract fabrication errors with the goal of speeding up the process and eliminating any need for human intervention. This approach is implemented as a cross-platform software product and programming library that can generate robot programs compatible with multiple industrial robot manufacturers. A physical prototype was fabricated using the seminal Panton Chair as a test model. We conclude that the computational approach is sound and most of the issues encountered were due to the equipment used. This will be addressed in future work.

summary	This study investigates design opportunities fostered by fabrication processes, ex-ploring manual and robotic forming. It links handcraft and digital fabrication techniques by implementing a motion capture system. It suggests physical prototyping as a novel form of design research, operating in the dynamic field between human capabilities, machine skills, and material behavior. This paper presents a series of experimental case studies created in a seminar taught by the author at Graz University of Technology. In this course, students con-duct tactile experiments, forming panels by hand and by robot, guided by the material behav-ior and reaction. Thereby, they explore the creation of architectural form in a dynamic inter-play between human, machine and material. Movement and speed of hand forming proce-dures are recorded into digital data, and then converted into machine code, driving a 6-axis industrial robotic arm. By using the same set-up for manual and robotic forming, both pro-cesses are relatable.

title	Open Source Factory: Democratizing Large-Scale Fabrication Systems

summary	Open source frameworks have enabled widespread access to desktop-scale additive manufacturing technology and software, but very few highly hackable large-scale or industrial open source equipment platforms exist. As research trajectories continue to move towards large-scale experimentation and full-scale building construction in robotic and digital fabrication, access to industrial fabrication equipment is critical. Large-scale digital fabrication equipment usually requires extensive start-up investments which becomes a prohibitive factor for open research. Expanding on the idea of the Fab Lab as well as the RepRap movement, the Open Source Factory takes advantage of disciplinary expertise and trans-disciplinary knowledge in construction machine design accumulated over the past decade. With the goal to democratize access to large-scale industrial fabrication equipment, this paper outlines the creation of two full-scale fabrication systems: a RepRap based large-scale 3-axis open source CNC gantry and a 6-axis industrial robot system based on a decommissioned KUKA KR200/2. Both machines offer radically different economic frameworks for implementing research in advanced full scale robotic fabrication into contexts of pedagogy, the research lab, practice, or small scale local building industry. This research demonstrates that such equipment can be implemented by building on the current knowledge base in the field. If industrial robots and other large-scale fabrication tools become accessible for all, the collective sharing of research and the development of new ideas in full-scale robotic building construction can be substantially accelerated.

title	High Resolution Representation and Simulation of Braiding Patterns
doi	https://doi.org/10.52842/conf.acadia.2017.670

summary	From the hand-crafted to the highly engineered, braided structures have demonstrated broad versatility across scales, materials, and performance types, leading to their use in a plethora of application domains. Despite this prevalence, braided structures have seen little exploration within a contemporary architectural context. Within the flora robotica project, complex braided structures are a core element of the architectural vision, driving a need for generalized braid design modeling tools that can support fabrication. Due to limited availability of existing suitable tools, this interest motivates the development of a digital toolset for design exploration. In this paper, we present our underlying methods of braid topology representation and physics-based simulation for hollow tubular braids. We contextualize our approach in the literature where existing methods for this class of problem are not directly suited to our application, but offer important foundations. Generally, the tile generation method we employ is an already known approach, but we meaningfully extend it to increase the flexibility and scope of topologies able to be modeled. Our methods support design workflows with both predetermined target geometries and generative, adaptive inputs. This provides a high degree of design agency by supporting real-time exploration and modification of topologies. We address some common physical simulation problems, mainly the overshooting problem and collision detection optimization, for which we develop dynamic simulation constraints. This enables unrolling into realistically straight strips, our key fabrication-oriented contribution. We conclude by outlining further work, specifically the design and realization of physical braids, fabricated robotically or by hand.
