summary	Advances in computational algorithmic design, material science, and fabrication technology have exposed architects to new opportunities in design and enabled them to address contemporary needs of cities and citizens. The far-reaching applications of this technology have provided students with a bewildering array of new tools for their design exploration. Among many of the socio-economic and political challenges facing today's world, homelessness and refugee crisis are the most critical. "Shape Your Shelter" design-build studio aimed to create a portable and transformable shelter using emergent technologies. This paper reviews some of the central concepts of such an endeavor and the role of computational design, digital fabrication, and material behavior as a medium of architectural design education and social services. It describes how these concepts can be used in a pedagogical framework to encourage student Innovation and increase students' engagement in new technological resources as they address critical contemporary and future social issues.

title	Designing for Digital Assembly with a Construction Team of Mobile Robots

summary	Advances in construction automation have primarily focused on creating heavy machines to accomplish repetitive tasks. While this approach is valuable in an assembly-line context, it does not always translate well for the diverse terrain and dynamic nature of construction sites. As a result, the use of automation in the architectural assembly has lagged far behind other industries. To address the challenges of construction-site assembly, this project suggests an alternative technique that uses a fl eet of smaller robots working in parallel. The proposed method, which is inspired by the construction techniques of insect colonies, has several advantages over the use of larger machines. It allows for much greater on-site fl exibility and portability. It is also easy to scale the operation, by adding or removing additional units as needed. The use of multiple small robots provides operational redundancy that can adapt to the loss of any particular machine. These advantages make the technology particularly suitable for construction in hazardous or inaccessible areas. The use of assembly robots also opens new horizons for design creativity, allowing architects to explore new ideas that would be unwieldy and expensive to construct using traditional techniques. In our tests, we used a team of small mobile robots to fold 2D laser-cut stock into 3D curved structures, and then assemble these units into larger interlocked forms.

title	Designing with Biomaterials for Responsive Architecture - A soft responsive "bio-structural" hydrogel skin
doi	https://doi.org/10.52842/conf.ecaade.2018.2.285
source	Kepczynska-Walczak, A, Bialkowski, S (eds.), Computing for a better tomorrow - Proceedings of the 36th eCAADe Conference - Volume 2, Lodz University of Technology, Lodz, Poland, 19-21 September 2018, pp. 285-292
summary	Synthetic biomaterials are not only widely explored in tissue engineering, but also present important opportunities in responsive architecture, especially soft structures and skins. In this paper we present how water-containing hydrogels can be adapted to digital fabrication techniques to design a soft responsive skin with integrated skeleton and surface. This research project details preliminary investigation into how tough hydrogels with different material properties can be designed and incorporated into laser-cutting and 3D printing methods typically used in architectural design. The outcome of this research produces an early prototype of thermally sensitive, tough hydrogel skin that responds to environmental stimuli such as temperature and moisture. Our work provides initial insights into how a soft responsive "bio-structural" architectural skin can be designed by integrating actuation, structure, and skins.

summary	Due to the highly interrelation between architecture and engineering involved in the early design stage of 3D printing, form-finding is the critical step in the large-scale 3D printing projects. This paper focused on the research of form-finding applied in large-scale 3D printed structures, specifically, in the design of two pedestrian bridges. A three-step form finding approach was introduced in this paper. Multiple numerical methods were involved in the approach to find an optimal solution for both aesthetics and structural design for two 3D printed pedestrian bridges. The application of the three steps of form-finding, which take consideration of material properties, site limitations, applied loads etc., to the design of the large-scale 3D printed bridges were discussed in details in this paper. The approach of form-finding in an early designing stage disused in this paper helps to understand the combination of architecture and structure engineering.

title	Pneumatically Actuated Material. Exploration of the mophospace of an adaptable system of soft actuators
doi	https://doi.org/10.52842/conf.acadia.2018.294
source	ACADIA // 2018: Recalibration. On imprecisionand infidelity. [Proceedings of the 38th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-17729-7] Mexico City, Mexico 18-20 October, 2018, pp. 294-301
summary	This research in progress investigates a design and fabrication method of an adaptable and programmable composite material in an embodied computation system. It develops a workflow for a behavior-based model, the exploration of the morpho-space associated with the combinatorial assembly and the actuation of soft elements. The aggregation of individually actuatable and soft units in a system creates a large potential regarding adaptability, flexibility and reconfigurability, through a non-rigid and non-mechanical system. The cells are developed through a process of prototyping on origami and auxetic pattern inspired soft robotic elements. Every soft cell is pneumatically actuated through a negative pressure environment. The computational simulation is informed by the prototyping process and its findings. The simulation-based design of such an assembled system allows prediction of the aggregated shape and outputs a sequencing table, describing the actuation status of every cell and can create a tool to communicate between material and computational system

title	The fabrication and application of parametric inflatable structure
source	SIGraDi 2018 [Proceedings of the 22nd Conference of the Iberoamerican Society of Digital Graphics - ISSN: 2318-6968] Brazil, São Carlos 7 - 9 November 2018, pp. 684-689
summary	This study uses parametric design to optimize the process and application of the inflatable method. Inflatable design has advantages of light weight, integral forming, volume change, etc., but the manufacturing process often requires the development of molds, a large number of manual heat seals, etc. Inspired by the structure principle of amputated wing tube structure, coupled with the advantages of parameterization and digital tool heat sealing, The same material can be made at different tightness, because the tight design with different angles has more structural characteristics and bending properties, thereby generating more complex spatial structures. Different materials also have corresponding manufacturing methods, which also increase the opportunities for application in architectural design.

title	Design of Robotically Fabricated Timber Frame Structures
doi	https://doi.org/10.52842/conf.acadia.2018.394
source	ACADIA // 2018: Recalibration. On imprecisionand infidelity. [Proceedings of the 38th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-17729-7] Mexico City, Mexico 18-20 October, 2018, pp. 394-403
summary	This paper presents methods for designing nonstandard timber frame structures, which are enabled by cooperative multi-robotic fabrication at building-scale. In comparison to the current use of automated systems in the timber industry for the fabrication of plate-like timber frame components, this research relies on the ability of robotic arms to spatially assemble timber beams into bespoke timber frame modules. This paper investigates the following topics: 1) A suitable constructive system facilitating a just-in-time robotic fabrication process. 2) A set of assembly techniques enabling cooperative multi-robotic spatial assembly of bespoke timber frame modules, which rely on a man-machine collaborative scenario. 3) A computational design process, which integrates architectural requirements, fabrication constraints, and assembly logic. 4) Implementation of the research in the design and construction of a multi-story building, which validates the developed methods and highlights the architectural implications of this approach.

title	Multiscale modeling frameworks for architecture: Designing the unseen and invisible with phase change materials
source	International Journal of Architectural Computing vol. 16 - no. 2, 104-122
summary	Multiscale design and analysis models promise a robust, multimethod, multidisciplinary approach, but at present have limited application during the architectural design process. To explore the use of multiscale models in architecture, we develop a calibrated modeling and simulation platform for the design and analysis of a prototypical envelope made of phase change materials. The model is mechanistic in nature, incorporates material-scale and precinct scale-attributes, and supports the design of two- and three-dimensional phase change material geometries informed by heat transfer phenomena. Phase change material behavior, in solid and liquid states, dominates the visual and numerical evaluation of the multiscale model. Model calibration is demonstrated using real-time data gathered from the prototype. Model extensibility is demonstrated when it is used by designers to predict the behavior of alternate envelope options. Given the challenges of modeling phase change material behavior in this multiscale model, an additional multiple linear regression model is applied to data collected from the physical prototype in order to demonstrate an alternate method for predicting the melting and solidification of phase change materials.

title	Full Integration: Closing the Gap on Technology Readiness
doi	https://doi.org/10.52842/conf.acadia.2018.098
source	ACADIA // 2018: Recalibration. On imprecisionand infidelity. [Proceedings of the 38th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-17729-7] Mexico City, Mexico 18-20 October, 2018, pp. 98-107
summary	This paper discusses the authors’ experiences and lessons learned through designing and constructing small- and large-scale robotic prototypes and the fully integrated use of VR and AR for design. Also of focus here are the methodological tools utilized to implement this student-led research in an interdisciplinary educational environment, as well as the design explorations of Mars habitation systems. Through the systems engineering approach, students will generate ideas that may or may not make it to the final design development stage, but may potentially be valuable to future real exploration habitats and mission architectures. The final prototype allows an assessment of the focus parameters, which are the vessels’ transformation capacities and layout adaption. The design objective of this project is to examine strategies for commonality between an interplanetary vehicle (IPV) and a Mars surface habitat. The presented design proposals address this challenge to create a common habitation system in both habitats so that crew members will be familiar with the layout, function, and location throughout the expedition. The design tools operate at the intersection of architectural layout design, mechanics, and structural design, and use origami folding techniques and structural form-finding concepts to generate shell action rigidity. In addition, the project develops a strategy for mobility and transformation of the surface habitat prior to its transformed configuration. The value here lies in understanding lessons from this strategy for both the design process as well as efficiency and optimization in design as a model for terrestrial design.

summary	This paper will discuss data visualisation in structural engineering for comparing design alternatives. By having the structural information of all different design proposals at hand, the designer is able to make informed design decisions. The authors developed a tool for creating interactive graphs while designing structures in a parametric design environment. In this work a case study of different structural design alternatives of a stadium roof is presented. Based on this design case, some graphs and the new informed design approach will be explained. Also the implementation of the tool within a parametric design environment with its advantages and issues is discussed.

title	Toward Adaptive Architectural Skins - Designing Temperature-Responsive Curvilinear Surfaces

summary	This research investigated the possibility of creating adaptable and precise curvilinear surfaces through the deformation of flat wooden surfaces. A prototype design system was developed to accomplish this task. The goal was to take a commonly-used architectural material, which is valued for its environmental sustainability and its aesthetic qualities, and to re-conceptualize it for use in cutting-edge adaptive digital designs. We therefore sought to develop a way to create wooden surfaces that could predictably transform in response to environmental stimuli. We successfully developed and tested the reversible deformation of a wooden surface by laminating a shape-memory polymer onto a kerfed wooden plane. The composite obtains its responsiveness from the shape-memory polymer, and its curvature direction and structural stability from the kerfed wood. The composite is able to deform to a defined curvilinear surface when heated to 40-60 degrees Celsius, and then self-transform back to the original flat surface when cooled. In addition to demonstrating kinetic behavior for a wood-based composite, the prototype offers a practical technique that can be used by designers to create flexible, inexpensive fabrication and packaging strategies.

title	Adaptive THERM-SKIN - Tunable Cellular Materials for Adaptive Thermal Control
doi	https://doi.org/10.52842/conf.caadria.2018.2.309

summary	This research investigates a tunable cellular material system that can alternate between a thermal insulator and a heat exchanger. The capability to morph between these two distinctive thermal functions provide opportunities to create novel material systems that can dynamically adapt to its environment. The operating principle is to strategically deform the cellular material so that the shape and size of the cavities are optimized for the intended thermal function. In the compressed state, the cavity spaces are narrow enough to suppress convection heat transfer and utilize the low thermal conductivity property of still air. The expanded state has the optimum cavity dimensions for air to move through the system and exchange heat with the material system. The first stage of the research utilizes the existing thermal optimization studies for establishing the analytical model for predicting the performance of each state as a function of the geometric features. The second stage constructs a parametric model using the predictions, and two separate material architectures were designed and fabricated based on it. The calibrated analytical model can be utilized in designing various dynamic thermal interaction systems at a wide range of conditions and parameters (e.g., climate, temperature, scale, and material).

title	Spaceship Tectonics - Design Computation Pedagogy for Generative Sci-Fi Building Skins

source	Kepczynska-Walczak, A, Bialkowski, S (eds.), Computing for a better tomorrow - Proceedings of the 36th eCAADe Conference - Volume 2, Lodz University of Technology, Lodz, Poland, 19-21 September 2018, pp. 357-366
summary	Sci-Fi architecture, both as digital or physical representations, despite their inherent intricacy, lack the spatial depth of a structured interior, material definition or program information. This discrepancy, combined with the plethora of available sci-fi motifs, inspired the development of an integrated teaching approach with the academic objective to utilize computational methods for analysis, reproduction and composition of generative building skins, and consequently architecture, which aims to be 'outside of this world' as a sci-fi design quality-enriched result of our reality. The proposed methodology is implemented at the Spaceship Architecture Design Studio at the University of Innsbruck. Its capacity to achieve a successful assimilation of design computation in the curriculum is subsequently assessed by the documentation and quantitative/qualitative evaluation of the designs developed during two academic years, in line with a generative facade articulation schema, without however undermining the rest of the virtues of tectonic spaces. The introduction of a theme like sci-fi where the design objective is not clearly defined, is examined in comparison to similar approaches, towards the corroboration of the pedagogical method proposed.

summary	The analysis of make-belief drawings and models of Sci-Fi spaceships and architecture, leaves architects usually in absence of interior, material or program information. The spatial depth of sci-fi digital or physical models is virtually non-existent and unresolved. This discrepancy within sci-fi scenarios inspired the development of an integrated teaching methodology within design studios, with the academic objective to utilize computational methods for analysis, reproduction and eventually composition, while assessing its capacity to achieve a successful assimilation of design computation in the curriculum. The Spaceship Architecture Design Studio at University of Innsbruck's Institute for Experimental Architecture.hochbau follows a procedural approach in which the design objective is not predefined. Yet, it aims to be 'outside of this world' as a sci-fi architectural quality-enriched result of our reality, via a design oriented course with immersive computational strategies.

title	New Concepts for Application of Topological Interlocking In Architecture
doi	https://doi.org/10.52842/conf.ecaade.2018.2.467
source	Kepczynska-Walczak, A, Bialkowski, S (eds.), Computing for a better tomorrow - Proceedings of the 36th eCAADe Conference - Volume 2, Lodz University of Technology, Lodz, Poland, 19-21 September 2018, pp. 467-476
summary	The paper concerns the issue of constructing flat vaults from elements topologically interlocking inspired by the Abeille blocks. One of the new ideas that are presented is constructing the vaults in an order opposite to the one considered untill now. The problem of static response on the thrust force, significant for flat vaults, is usually solved by the use of the perimeter frame, added only after arranging all the elements of the vault. The paper presents how to arrange the vault inside a previously made frame thanks to application of special components divided into parts, which are inserted at the end and play the same role as a keystone in a stone arch. The other new concept is shaping vaults based on equilateral triangles and regular hexagons, from hexagonal, romboidal and triangular elements shaped and arranged in a manner similar to the one used for shaping square vaults. The last innovative concept presented in a paper concerns shaping the perimeter frame from the components providing stiffness of the frame only due to topological interlocking. All presented ideas have been analised purely at a geometric level.

summary	Knowledge of geometric properties of surfaces is crucial for resolution of many manufacturing problems. Developability is an important feature of a surface that allows its manufacture from a flat "strip" of a "flexible" and "non-deformable" material. Digital fabrication technologies and parametric design tools, based on knowledge of geometry, are changing designer way to think. Our research in the field of non-developable surfaces fabrication move from paneling to "kerfing". This technique allows to transform a rigid material in a flexible one. The main problem to solve is how to cut the flat shape to obtain the design surface.

summary	While textile composites offer a wide range of formal flexibilities, a primary concern is the cost and time of creating custom mold surfaces which are typically produced through subtractive digital fabrication techniques. Alternative methods such as adjustable molds are used in high-end sail-making, and architectural researchers have examined reconfigurable molds, fiber sandwich fabrication methods, and mold-free fiber reinforced polymer (FRP) fabrication processes. In this paper, we discuss the development of a digitally controlled mold system for complex-shaped textile composite panels, aiming to reduce the need for custom milled molds. Experimental research started with producing composite samples from computer-numerically-controlled (CNC) milled foam molds. Subsequently, a digitally controlled deformable mold prototype was developed which incorporates a digital interface through which the architect's surface geometry is entered, analyzed, and transferred. The digital geometry directly controls the position of vertical actuators which adjusts the mold surface. Results of this ongoing project outline a digital process for fabricating textile composite panels, and help to define key parameters of the adjustable mold system including material properties, mechanical controls of the mold surface, paneling considerations, and digital interface.

summary	The presented paper discusses the combination of cutting edge technology (i.e. 3D-pinting) and raw natural grown resources (i.e. bamboo) to develop resource efficient load carrying truss structures in architectural scale. Via visual sensing the individual material properties of various bamboo poles are analyzed and directly used to inform the digital model. Comparing load carrying capacity of the bamboo pole and structural requirements of the design, the poles are placed and the connections designed. Conventional 3D-pinters produce the nodes and connectors and enable to merge natural and "digital" materiality.

summary	InterLoop employs previously developed workflows that enable multi-planar robotic bending of metal tubes with high accuracy and repeatability (Huang and Spaw 2022). The scale and complexity is managed by employing augmented reality (AR) technology in two capacities, fabrication and assembly (Jahn et al. 2018; Jahn, Newnham, and Berg 2022). The AR display overlays part numbers, bending sequences, expected geometry, and robot movements in real time as the robot fabrication is occurring. For assembly purposes, part numbers, centerlines, and their expected positional relationships are projected via quick response (QR) codes spatially tracked by the Microsoft Hololens 2 (Microsoft 2019). This is crucial due to the length and self-similarity of complex multi-planar parts that make them difficult to distinguish and orient correctly. Leveraging augmented reality technology and robotic fabrication uncovers a novel material expression in tubular structures with bundles, knots, and interweaving (Figure 1).
