title	On-site Robotic Assembly of Double-curved Self-supporting Structures
source	SIGRADI 2015 [Proceedings of the 19th Conference of the Iberoamerican Society of Digital Graphics - vol. 2 - ISBN: 978-85-8039-133-6] Florianópolis, SC, Brasil 23-27 November 2015, pp. 746-753.
summary	Robotic assembly of architectural structures has been an area of research for a few decades. Yet, current methods impose a large number of constraints on the geometry of those structures. In this paper we introduce a method for robotic assembly that enables the construction of double curved self-supporting structures. Latest research challenges have focused on the assembly of sophisticated brick structures and on sensor feedback systems for handling accuracy. We propose an alternative strategy to tackle tolerance handling in complex structures that rely on geometry. The intelligence of the system lies in two main aspects: a subdivision technique that incorporates the robot’s constraints as well as the structural equilibrium of the structure during each step of assembly, in order to omit the use of scaffolding; and a match between geometric information and the robot’s movements in a robot programming environment. As a proof of concept, we fabricated a portion of a full-scale double-curved structure. The structure was assembled without scaffolding by a portable KUKA KR10 on a randomly picked site. This project aims to demonstrate an easy and simple method for robotic assembly that enables the realization of digitally generated complex geometries as concrete complex structures.

summary	This paper presents an ongoing research, aiming to introduce a fabrication procedure for the development of tensile mesh systems. The purpose of this methodology is to be implemented in real time, based on a feedback loop logic cyclically iterated between robotic machine control and elastic material behaviour. Our purpose is to extend the capacity of robotically driven mechanisms to the fabrication of complex tensile structures and at the same time, reduce the defects that might occur due to the deformation of the elastic material. In this paper, emphasis is given to the development of a custom-made end effector tool, which is responsible to add elastic threads and create connections in the form of nodes. Based on additive fabrication logic, this process suggests the real time development of physical prototypes through the increasing smoothness of mesh structures.

summary	There has been a recent increase in the exploration of mereological systems, speculating on how digital design, assembly and reconfiguration of digital materials (Gershenfeld, 2015) enables digitally informed physical worlds that change over time. Besides opportunities for construction and design automation, there is a potential to reimagine how multiple stakeholders can participate in the computational decision-making process, using the benefits of the mass customization of logistics (Retsin, 2019). This paper presents a research-by-design project that applies a digital and discrete material system to high-rise housing in Hong Kong. The project has developed an integrated approach to design, construction, and inhabitation, using a system of discrete parts which can be assembled in various apartment configurations, to incorporate varying occupants requirements and facilitate negotiations and changes over time.

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).

summary	Brick construction has a long and rich structural and aesthetic traditions in architecture, which can be traced back to the origins of our civilization. However, despite the remarkable works of Frank Lloyd Wright, Louis Kahn, Eladio Dieste or Alvar Aalto in the 20th century, the application of this construction process to address more irregular geometries is very difficult to be achieved by conventional manual means. In this context, the last decade assisted to emergence of robotic applications in architecture. While Gramazio & Kohler looked for solving non-standard brick structures, others, like the S.A.M. robot initiative, are interested in improving the productivity in the fabrication of regular brick structures. By surveying the recent advances on bricklaying automation, this paper is interested in reflecting on the actual role of manual brickwork. In doing so, the authors present the Brick Tower experiment developed at the DFL/CEAU/FAUP, where two different fabrications processes are critically compared: a robotic and a manual one, which is aided by a video projection technique. By describing and illustrating this experiment, the authors argue that it is possible to expand the traditional craft of bricklaying by devising simple strategies to increase the human capacity to understand and materialize more elaborated geometries. This research avenue can be relevant if one considers that manual work should remain the most common form of brickwork practice in the next decades.

title	Robotic Design-Fabrication - Exploring Robotic Fabrication as a Dynamic Design Process

summary	This research explores the relationship between digital design and digital fabrication, investigating robotic fabrication as a dynamic design process. It examines the potential of utilizing production tools as the key part of the design process, where the final geometry is neither simulated nor pre-defined in the digital realm before materialization. This “design-fabrication” or “design-by-fabrication” workflow fosters a new way of thinking about architectural design and practice, as well as unlocking creativity and discovering new geometries and aesthetics. To illustrate this, the paper presents a series of directed design experiments developed by students in two seminars at Graz University of Technology. A unique fabrication technique is investigated, combining laser cutting and robotic thermoforming, which was developed by the author in the course of her PhD-research. Utilizing this robotically aided design process, sheets of acrylic glass are laser cut and thermoformed by a robot into 3- dimensional spatial objects, each element with individual geometries, textures, transparencies and apertures.

summary	Print-Cast Concrete investigates concrete 3D printing utilizing robotically fabricated recyclable green sand molds for the fabrication of thin shell architecture. The presented process expedites the production of doubly curved concrete geometries by replacing traditional formwork casting or horizontal corbeling with spatial concrete arching by developing a three-dimensional extrusion path for deposition. Creating robust non-zero Gaussian curvature in concrete, this method increases fabrication speed for mass customized elements eliminating two-part mold casting by combining robotic 3D printing and extrusion casting. Through the casting component of this method, concrete 3D prints have greater resolution along the edge condition resulting in tighter assembly tolerances between multiple aggregated components. Print-Cast Concrete was developed to produce a full-scale architectural installation commissioned for Exhibit Columbus 2019. The concrete 3D printed compression shell spanned 12 meters in length, 5 meters in width, and 3 meters in height and consisted of 110 bespoke panels ranging in weight of 45 kg to 160 kg per panel. Geometrical constraints were determined by the bounding box of compressed sand mold blanks and tooling parameters of both CNC milling and concrete extrusion. Using this construction method, the project was able to be assembled and disassembled within the timeframe of the temporary outdoor exhibit, produce <1% of waste mortar material in fabrication, and utilize 60% less material to construct than cast-in-place construction. Using the sand mold to contain geometric edge conditions, the Print-Cast technique allows for precise aggregation tolerances. To increase the pavilions resistance to shear forces, interlocking nesting geometries are integrated into each edge condition of the panels with .785 radians of the undercut. Over extruding strategically during the printing process casts the undulating surface with accuracy. When nested together, the edge condition informs both the construction logic of the panel’s placement and orientation for the concrete panelized shell.

title	In-Situ Robotic Fabrication of Spatial Glulam Structures
source	Jeroen van Ameijde, Nicole Gardner, Kyung Hoon Hyun, Dan Luo, Urvi Sheth (eds.), POST-CARBON - Proceedings of the 27th CAADRIA Conference, Sydney, 9-15 April 2022, pp. 41-50
doi	https://doi.org/10.52842/conf.caadria.2022.2.041
summary	While current approaches in timber construction stress the advantages of off-site prefabrication, glued laminated timber(glulam) structures is limited to the constraints of standardized, prefabricated mostly linear elements, which also lends itself only to building typologies that offer an increased level of standardization and regularity. The design freedom of timber structures is incomparable to that of reinforced concrete structures, which mostly gains from the in-situ fabrication process. An in-situ robotic timber fabrication platform allows the on-site construction of glulam structures with highly differentiated networks of beams composed of robotically assembled discrete linear elements. Based on the possibilities of such mobile robotic fabrication process, this paper explores novel architectural typologies of spatial glulam structures. The research is conducted from several aspects including joint tectonics, design method, and robotic fabrication process. A large-scale pavilion is designed and fabricated to verify the feasibility of the proposed system. This research could provide a novel mode of in-situ robotic timber fabrication and corresponding glulam structure system for timber construction.

University of Pennsylvania Stuart Weitzman School of Design. 27-29 October 2022. edited by M. Akbarzadeh, D. Aviv, H. Jamelle, and R. Stuart-Smith. 4-23.
summary	This paper presents a computational design method that integrates capabilities to manage material and fabrication tolerances occurring during the robotic assembly of spatial timber structures with tight-fit connections. This is achieved by building a data-base of tolerances measured during the robotic assembly process, which then allow for tolerance simulation as part of an assembly sequence planning method based on the Kruskal algorithm. Through a combination of optimization and linear regression techniques, the developed method enables designers to minimize deviations of their designs and diminish the risks of misfits during fabrication. In consequence, it allows for tolerance-aware designs.

doi	https://doi.org/10.52842/conf.caadria.2022.2.111
summary	This paper presents a novel approach to computationally designed and robotically assembled modular timber-only structures with traditional wood joinery methods. We geometrically adapt and parametrize five traditional joint typologies to compensate for robotic placement inaccuracies and comply with modern structural requirements. The force-locking capacity of the connections is utilised to support the robotic assembly of five unique timber frame modules of 5.5 by 2.2 by 2.5 metres, each with a unique timber lattice pattern. For each major joint typology we conduct a series of structural load-tests to evaluate the structural performance. We develop a custom software to enable architects and engineers to interactively design with those principles, taking into account both structural and production feasibility constraints. As a demonstration of our design approach, the five modules were robotically assembled using the described methods.

summary	This paper attempts to reconsider the role of advanced tools and their effective implementation in the field of Architecture, Engineering and Construction (AEC) through the concept of sustainable construction. In parallel, the paper aims to discuss and find common ground for communication between industrial and experimental processes guided by sustainable criteria, an area of investigation that is currently in the forefront of the research work conducted in our robotic construction laboratory. Within this frame, an ongoing work into the design, analysis and automated construction of a timber structure in actual scale is exemplified and used as a pilot study for further discussion. Specifically, the structure consists of superimposed layers of timber elements that are robotically cut and assembled together, formulating the overall structural system. In order to achieve a robust, reliable and economically feasible solution and to control the automated construction process, a multi-objective design optimization process using evolutionary principles is applied. Our purpose is to investigate possibilities for sustainable construction considering minimization of cost and material waste, and in parallel, discussing issues related to the environmental impact and the feasibility of solutions to be realized in actual scale.

doi	https://doi.org/10.52842/conf.acadia.2018.358
summary	This paper presents the development of an integrative and adaptive robotic fabrication process for the production of wooden-based segmented shells of variable thickness. A material and construction process is presented whereby an industrial robot with a two-degree of freedom end-effector acts as active form-work, positioning flexible strips of plywood so they can be assembled into a structurally performative configuration and then filled with a polyurethane expandable foam. The resulting material system is a structurally performative and doubly curved sandwich composite which performs well in bending. This paper discusses the construction process and the material system, methods for structural analysis, an adaptive robotic fabrication process, as well as a computational design tool which integrates material constraints, robotic constraints, and structural performance. The resulting construction system expands the design possibilities for robotic fabrication in wood, particularly as a viable material system for implementation directly in an on-site condition.

summary	This paper presents a novel robotic assembly method for timber structures with integral timber joints, specifically, crossed-half-lap joints. The proposed method uses a set of custom-built, remote-controlled, high-force robotic clamps to operate in collaboration with an industrial robotic arm to overcome challenges of robotic timber joint assembly, such as providing large assembly forces and correcting misalignments. This method enables automatic assembly of non-repetitive and spatially connected timber structures. We developed custom software for modelling, visualization and feasibility-checking for structures compatible with the proposed assembly method. As a proof of concept, we designed and robotically assembled a spatial frame structure (4.8 x 3.0m footprint, 3.4m tall) comprising 40 pieces of 100x100mm profile timber elements.

summary	The recent convergence of computational design and digital fabrication has made new forms of architectural materialization possible. A workshop conducted at the Royal Melbourne Institute of Technology investigated how differentiated lightweight metal structures may be designed and fabricated under these new conditions. The workshop aim was to complete three such structures; each one is aggregated from aluminum profiles that are robotically assembled according to computationally driven geometric logics. The key challenge was to enable participants, assumed to lack programming and robotic fabrication experience, to design and construct their structures within imposed time constraints. This paper describes the subsequent development of accessible computational design tools and a robust robotic fabrication method for the workshop, and highlights the key decisions taken with their implementation. The workshop results are discussed and the design tools evaluated with respect to them. The paper concludes by recommending an approach to developing computational design tools which emphasizes the importance of usability and integration with the fabrication process.

summary	Ashen Cabin, designed by HANNAH, is a small building 3D-printed from concrete and clothed in a robotically fabricated envelope made of irregular ash wood logs. From the ground up, digital design and fabrication technologies are intrinsic to the making of this architectural prototype, facilitating fundamentally new material methods, tectonic articulations, forms of construction, and architectural design languages. Ashen Cabin challenges preconceived notions about material standards in wood. The cabin utilizes wood infested by the Emerald Ash Borer (EAB) for its envelope, which, unfortunately, is widely considered as ‘waste’. At present, the invasive EAB threatens to eradicate most of the 8.7 billion ash trees in North America (USDA, 2019). Due to their challenging geometries, most infested ash trees cannot be processed by regular sawmills and are therefore regarded as unsuitable for construction. Infested and dying ash trees form an enormous and untapped material resource for sustainable wood construction. By implementing high precision 3D scanning and robotic fabrication, the project upcycles Emerald-Ash-Borer-infested ‘waste wood’ into an abundantly available, affordable, and morbidly sustainable building material for the Anthropocene. Using a KUKA KR200/2 with a custom 5hp band saw end effector at the Cornell Robotic Construction Laboratory (RCL), the research team can saw irregular tree logs into naturally curved boards of various and varying thicknesses. The boards are arrayed into interlocking SIP façade panels, and by adjusting the thickness of the bandsaw cut, the robotically carved timber boards can be assembled as complex single curvature surfaces or double-curvature surfaces. The undulating wooden surfaces accentuate the building’s program and yet remain reminiscent of the natural log geometry which they are derived from. The curvature of the wood is strategically deployed to highlight moments of architectural importance such as windows, entrances, roofs, canopies, or provide additional programmatic opportunities such as integrated shelving, desk space, or storage.

summary	Throughout this paper, we introduce a novel design-driven method for the robotic assembly of unit-based structures. The goal of this research is to establish a method to robotically fabricate discrete structures, using pick-and-place robotic manipulation and customized 3D-printed geometric units. Thus, the methodology allows for the bespoke discretization of architectural solid models into interlocking architectural units. Investigating how design can reduce error in the robotic fabrication process, a significant feature of this research is the application of mechanical coupling for the creation of self-interlocking geometry. This method is able to correct errors in robotic manipulation for the precise robotic fabrication of architectural structures. Reducing errors in the assembly process through the design of geometric units expands the field of architectural robotics to designers. Through a series of assembled architectures, fabricated through both additive and subtractive manufacturing techniques, the research explores the idea of an automated system producing unit-based structures using pick-in-place robotics and digitally fabricated units.

summary	The Dougong (brackets set) is a traditional Chinese capital used to transfer the load of the roof to a column. It is known for its anti-seismic properties, sustainability, and cultural significance. This paper introduces a framework for parametric design and robotic fabrication of the Dougong, thus it can be utilised in contemporary architecture. The framework incorporates topology optimisation, voxelisation, multi-objective optimisation and robotic assembly and is verified by designing and assembling a timber frame column out of Dougong units. Our findings highlight the potential of utilising the Dougong in contemporary design as well as a strategy to reduce the tolerances of robotically assembled tenon-mortise elements.

summary	Responsive architecture is one of the growing areas of computational design that is not getting adequate attention in CAAD curricula. A pedagogical approach to designing responsive systems requires more than the typical knowledge, tools or skill sets in architectural design studios. This paper presents a framework for integrating responsive and kinetic systems in the architectural design studio. The framework builds on findings of two design studios conducted at The American University in Cairo, Egypt. In both studios, students were asked to design elements of responsive architecture that work towards the development of their projects. The paper demonstrates the process and outcomes of both studios. It then demonstrates how concepts of integrated project delivery are incorporated to propose a framework that engages students in designing, fabricating and operating responsive systems in different phases of the design process. A discussion follows regarding dynamics of design studio in light of the proposed framework.
