summary	The research presented in this paper focusses on the prefabrication of wood building systems using human craft and robotic machines as equal actors in collaborative fabrication processes. It uses self-developed components such as a data managing framework system to generate and exchange fabrication data between the design elements and the fabrication environment. Human robot collaboration via augmented reality (AR) technology is facilitated through a software framework and applied in the prefabrication of timber structures. Based on previous research, this iteration uses the concept of multi-actor fabrication and extends the number of human actors in the fabrication process. A case study was conducted for the collaborative fabrication of a timber structure. Five actors (four humans and one 7-axis robotic system) received instructions based on their individual skill set and collectively manufactured a timber structure in an organized workflow.

summary	This paper presents a case study of collaborative human-robot construction, in the form of a 10-day workshop in robotically assisted construction of curved timber surfaces. The construction process developed for the workshop shows that employing computational design in combination with industrial robots can result in a demand for various kinds of labor, with a range of skill levels: in addition to tasks requiring specialized computational design skills, the proposed construction process also leads to simplification of construction tasks, by eliminating the need to measure on-site.

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	Augmented Reality Assisted Robotic: Tube Bending

summary	The intent of this research is to study potential improvements and optimizations in the context of robotic fabrication paired with Augmented Reality (AR), leveraging the technology in the fabrication of the individual part, as well as guiding the larger assembly process. AR applications within the Architecture, Engineering, and Construction (AEC) industry have seen constant research and development as designers, fabricators, and contractors seek methods to reduce errors, minimize waste, and optimize efficiency to lower costs (Chi, Kang, and Wang 2013). Recent advancements have made the technology very accessible and feasible for use in the field, as demonstrated by seminal projects such as the Steampunk Pavilion in Tallinn, Estonia (Jahn, Newnham, and Berg 2022). These types of projects typically improve manual craft processes. They often provide projective guidelines, and make possible complex geometries that would otherwise be painstakingly slow to complete and require decades of artisanal experience (Jahn et al. 2019). Building upon a previously developed robotic tube bending workflow, our research implements a custom AR interface to streamline the bending process for multiple, large, complex parts with many bends, providing a pre-visualization of the expected fabrication process for safety and part-verification purposes. We demonstrate the utility of this AR overlay in the part fabrication setting and in an inadvertent, human-robot, collaborative process when parts push the fabrication method past its limits. The AR technology is also used to facilitate the assembly process of a spatial installation exploring a unique aesthetic with subtle bends, loops, knots, bundles, and weaves utilizing a rigid tube material.

summary	Within the literature, there has been growing number of studies on robotic 3D printing of clay-based materials. Building upon this foundation and with the aim of improving environmental and structural performance of 3D printed blocks, this paper proposes a material mixture for robotic clay printing, particularly for remote settlements. Exploring three different mixtures of clay and algae for the base material, the paper particularly investigates the relations between the percentage of algae in the mixture and the resulted structural integrity of printed blocks by the UR10 robot. The printed blocks with different algae percentages are compared for their shrinkage rate, fissure sizes and deformation by evidence collected through photography and 3D scanning. The paper presents the initial outcomes of an ongoing research, highlights the positive effects of algae in the mixture for structural performance of the blocks. The proposed algae-based high-performance clay-based materials are designed to generate lower CO2 emissions as well. Adapting higher and collaborative construction technologies, the proposed material mixture and the outcome of the research would inform upgrading clay-based constructions in indigenous communities and moves towards a novel digital culture in remote societies.

title	Mixed Reality Interactive Representations for the Assembly of a Custom Timber Tower
source	Dokonal, W, Hirschberg, U and Wurzer, G (eds.), Digital Design Reconsidered - Proceedings of the 41st Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2023) - Volume 2, Graz, 20-22 September 2023, pp. 751–760

summary	In recent years, many projects have emerged testing the use of augmented reality (AR) and mixed reality (MR) systems in the custom design and fabrication of architectural projects at a variety of scales using digital and analog tools. This paper presents a series of MR systems for key modes of interactive representations in the assembly process of a custom timber tower, intending to expand an area of research on the use of MR as a critical medium for architectural representation in design customization. The series of MR systems were developed to assist and expedite the physical assembly of customized timber parts and connections for the large-scale tower with a small team of students and carpenters. The MR systems are built as interactive representations of the 3D digital design model, allowing the user to see connections in real-time on physical materials in order to perform collaborative preparation and assembly tasks with analog tools. Each MR system relied on a single user, wearing a HoloLens 2, to use hand gestures to place and interact with 3D Rhino model representations of the tower and individual parts overlaid in the physical context at 1:1 scale. The MR systems deployed as interactive 3D representations were evaluated at three key stages in the material preparation and assembly processes. The project tested the use of MR systems created for a series of tasks that enabled the fast assembly of the tower, which is almost 10 meters high. The outlook explores the perspective of how MR systems augment modes of architectural representation through human interaction, collaboration, and accessibility (also for non-expert users), using digital and analog tools, and how these systems provide greater agency for customization and variety in design and building.

title	Cobotic Matters – Collaborative Robots and Discrete Assembly Design: From Stacking to Self-Interlocking of Reciprocal Components
source	Immanuel Koh, Dagmar Reinhardt, Mohammed Makki, Mona Khakhar, Nic Bao (eds.), HUMAN-CENTRIC - Proceedings of the 28th CAADRIA Conference, Ahmedabad, 18-24 March 2023, pp. 241–250
doi	https://doi.org/10.52842/conf.caadria.2023.2.241
summary	This paper presents a set of design-to-robotic assembly workflows developed based on the potential of working with collaborative robots. The research presents three assembly systems benefiting from several features of a seven-axis cobotic arm. The proposed methods are advanced as an integral part of an interdisciplinary project-based course entitled Cobotic Matters. The interdepartmental research builds upon the premise that human-robot collaboration, programable fabrication, and assembly technologies will fundamentally change how we design and build. Each case study explores different strategies for designing the assembly sequence of discrete elements and the growth direction of the structure. The presented methods cover a range of assembly approaches, including vertical stacking of cuboid wooden pieces, interlocking of unique prefabricated elements, and oblique growth of bespoke reciprocal components in multiple directions. In each case study, a specific assembly method is developed, and all three projects address the role of implementing cobotic systems in integrated computational design to robotic assembly workflows.

title	Annotation on Interactive Design Data in Design Analytics Tools

summary	Evaluating and deciding on design alternatives is a collaborative activity involving design teams and other design stakeholders in the Architecture Engineering and Construction (AEC) industry. Current tools for design offer limited support for data-informed collaborative decision-making and fall short of encouraging discussions. In a user study with eight domain experts, we investigated how a meaningful data-informed collaboration can be enabled in design through interactive visualizations of design alternatives. We argue that receiving feedback from the design stakeholders as annotations directly on data representations can improve design decision-making. The initial results from our study reveal extensive needs for multi-target coordinated annotations, sorting, and organizing annotations, and agility in creating and accessing annotations. We propose a set of high-level interactions and requirements for coordinated annotation for engaging in collaborative decision-making.

title	Imprinting Concrete Graded Transparency in 3D Concrete Printing Walls
source	Immanuel Koh, Dagmar Reinhardt, Mohammed Makki, Mona Khakhar, Nic Bao (eds.), HUMAN-CENTRIC - Proceedings of the 28th CAADRIA Conference, Ahmedabad, 18-24 March 2023, pp. 169–178
doi	https://doi.org/10.52842/conf.caadria.2023.2.169
summary	Robotic fabrication technologies enable customisation and automation for the construction industry. Specifically, 3D Concrete Printing (3DCP) has advanced rapidly in recent years with innovations in robotics, material science, and large-scale application. While 3D printed walls take up most of the applications of the technology at an architectural scale, the design and fabrication methods based on multi-materiality are limited. This paper presents a method for the creation of walls with graded transparency by embedding glass rods in between the printed concrete layers. To achieve this, a computational design tool was developed to explore the distribution of transparent rods within the opaque mass of concrete. Furthermore, the designs are tested with two fabrication methods based on human-robot collaboration and multi-robot fabrication processes by simultaneously 3D printing concrete and placing the rods. The presented results and identified challenges outline the potential of multi-material additive manufacturing methods for architectural applications materialised either through human-robot collaboration or as a multi-robotic fabrication process.

title	Layer-by-Layer Pick and Place Collaboration Between Human and Robot Using Optimization
source	Dokonal, W, Hirschberg, U and Wurzer, G (eds.), Digital Design Reconsidered - Proceedings of the 41st Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2023) - Volume 1, Graz, 20-22 September 2023, pp. 769–778
doi	https://doi.org/10.52842/conf.ecaade.2023.2.769
summary	Robotic pick-and-place (P&P) has been widely utilized in manufacturing and architectural construction since the 1980s. However, the lack of inherent sensing capabilities in robots has limited their ability to adapt and respond to changes in design or environment. To address some of these shortcomings, this paper proposes an interactive robotic brick-laying workflow using a vision-based sensing framework to inform and optimize brick placements in consecutive layers. The proposed implementation is comprised of three major computational frameworks: (1) digitally reconstructing and analyzing the current state of the assembly, (2) optimizing placement targets based on the digital representation of the environment and desired multi-objective optimization goals, and (3) planning robot motion for the next layer of brick-laying. Within this workflow, the vision-based feedback pipeline simultaneously reconstructs and localizes the already-built assembly. This geometric information constitutes the basis for the multi-objective optimization stage. The placement targets are adaptively calculated to build the next layer upon the existing assembly while optimizing for structural stability, accounting for unforeseen deviations between layers, and allowing for human intervention and modification throughout the process. By proposing an interactive robotic brick-laying workflow, the paper explores the prospects for leveraging the capabilities of robotic pick-and-place technology and integrating it with vision-based sensing frameworks to achieve optimal results in construction. Furthermore, by examining the effectiveness of a multi-objective optimization method as an adaptive design driver, this paper contributes to the development of novel computational strategies that can enhance the flexibility and adaptability of robotic construction systems.

doi	https://doi.org/10.52842/conf.caadria.2023.2.119
summary	The paper presents a novel process of fabricating concrete columns using 3-dimensional (3D) knitted fabric in conjunction with an industrial robotic arm acting as scaffolding. The research explores the feasibility of using wool as a biomaterial for fabricating formwork, thereby reducing construction waste and weight compared to traditional steel, fibreglass, or timber techniques. By examining the knit architecture in conjunction with experiments in slump admixture and tensile testing of the fabric formwork, the research developed several full-scale prototypes. The outcomes were scanned and analysed to understand the geometric deviation as a result of repeat usage of the fabric as formwork. The research demonstrates the resilience of the knitted wool fabric as formwork for concrete casting.

Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 318-328.
summary	The architecture and construction industries have been developing methods to integrate Augmented Reality (AR) and Mixed Reality (MR) workflows into the building industry for 1-to-1 scale design, visualization, and paperless fabrication. While these AR workflows have been primarily focused on mono-material assemblies, this paper investigates the potential of AR and MR for multi-material fabrication, combining various materials and structural components throughout each phase of the construction of the Unlog Tower. The installation uses infested and dying ash trees to construct a 36-foot-tall triangular, lightweight timber structure. The Unlog Tower leverages bending active elastic kinematics to stretch robotically kerfed logs braced by threaded rods and tube steel. Three extended reality (XR) workflows were explored for the construction of this bespoke timber struc- ture: (1) fiducial marker coordinated AR instruction, (2) multiple QR code AR instruction, and (3) gesture-based MR instruction. These XR workflows incorporate feedback-based construction notation and animation for the assembly of non-standard natural materials and standardized parts through three construction phases: materials to parts, parts to prefab modules, and onsite assembly. The research highlights the potential of AR and MR workflows for human-machine interaction in robotic fabrication, analog means of making, prefabrication, onsite construction, and coordination. The result of this investigation has demonstrated many advantages and disadvantages of varying AR/MR workflows in facili- tating the construction of multi-material and multi-phase structural assemblies.

title	Intelligent Packing and Unpacking Navigation of Prefabricated Metal Joint Timber Frame
source	Immanuel Koh, Dagmar Reinhardt, Mohammed Makki, Mona Khakhar, Nic Bao (eds.), HUMAN-CENTRIC - Proceedings of the 28th CAADRIA Conference, Ahmedabad, 18-24 March 2023, pp. 343–352
doi	https://doi.org/10.52842/conf.caadria.2023.1.343
summary	The packing and transportation of building materials is an important process in building construction. There are many small construction sites in Japan, where it is impossible to take all building materials out of the vehicles and store them on the site at one time. At the same time, many customized structural parts are often involved in building construction now. Their size and shape do not have fixed specifications like standardized building materials. In this article, automatic packing and analysis evaluation algorithms were written in Rhinoceros and Grasshopper environments to help users calculate and generate multiple results after loading the same wood in different order, and evaluate each result in multiple aspects. It is convenient for users to compare the advantages and disadvantages of different loading methods and finally choose the appropriate scheme. Finally, a packing case is analyzed by this algorithm, and the analysis results were obtained in a short time. Experimental results show that the algorithm can solve the problem effectively and successfully, and it has high practical value.

doi	https://doi.org/10.52842/conf.caadria.2023.2.159
summary	This research aims to develop a craft system that integrates design, construction, and tool-making for handcraft to become simpler and more accessible for non-professionals, even if it is a complex structure. Kigumi, a traditional Japanese wooden technique, inspires this research. In the experiment, a modified circular saw was developed to handcraft the "Kigumi shelf." Constraints in the craft process are closely connected to design, construction technique, and the use of tools in handcraft. The relationship between these constraints was managed and explored throughout the project, from developing systems to assembly. The developed system presents a comprehensive workflow, from reading QR codes on timber pieces to processing data and cutting. This study showed how we should treat technology to make it easier for non-professionals to engage with handcraft. Also, digital-aided technology is an effective way to enhance participation in handcraft.

doi	https://doi.org/10.52842/conf.caadria.2023.2.281
summary	As mass timber construction has become increasingly ubiquitous, doubly curved glued laminated timber (glulam) grid shell structures have challenged standard methods of glulam manufacturing which rely on a wasteful process of planing dimensional lumber into thin lamellas for lamination. The resulting glulam blanks are either milled or cut into doubly curved glulam blanks thereby discarding even more material. Instead of using dimensional lumber to manufacture doubly curved glulam and cross-laminated timber (CLT) blanks, Twistedlam is a robotic fabrication method that intervenes in the glulam and CLT manufacturing process at the sawmill stage, to cut sets of doubly curved boards from a log with a 6-axis robotic arm and bandsaw end effector. The boards were laminated into two hyperbolic paraboloid prototypes: a doubly curved glulam column and a doubly curved CLT blank. Through the construction of these two prototypes, the method not only reduces the amount of discarded material but also simplifies the lamination of the process by eliminating the spring-back produced from twisting flat boards into doubly curved boards for lamination of doubly curved glulam and CLT blanks.

doi	https://doi.org/https://doi.org/10.1007/978-981-15-6568-7_9
summary	Robotic Timber Construction has been widely researched in the last decade with remarkable advancements. While existing robotic timber construction technologies were mostly developed for specific tasks, integrated platforms aiming for industrialization has become a new trend. Through the integration of timber machining center and advanced robotics, this research tries to develop an advanced timber construction platform with multi-robot system. The Timber Construction Platform is designed as a combination of three parts: multi-robot system, sensing system, and control system. While equipped with basic functions of machining centers that allows multi-scale multifunctional timber components’ prefabrication, the platform also served as an experimental facility for innovative robotic timber construction techniques, and a service platform that integrates timber structure design and construction through real-time information collection and feedback. Thereby, this platform has the potential to be directly integrated into the timber construction industry, and contributes to a mass-customized mode of timber structures design and construction.

summary	The field of architecture is experiencing transformative changes with the rise of Artificial Intelligence (AI). This study investigates the use of generative models like Large Language Models (LLM) and Generative Diffusion Models (GDM) in architectural design, focusing on sustainability. Utilizing the concept of “active human agency”, the research evaluates tools like DALL-E 2 (Bing) and ChatGPT (GPT-4) for creating environmentally responsive references in the early phases of the design process. Employing an explorative and qualitative methodology, the investigation includes architectural characteristics of climatic archetypes and concepts related to architecture-biology, applied to different environmental contexts. Initial findings reveal the AI potential in creating environmentally responsive references, with certain limitations in specific interactions and interpretations. The conclusion emphasizes these tools as collaborative aids in early design stages, and underscores the importance of "active human agency" for meaningful, responsible results, contributing to sustainability in early architectural design processes.

summary	In Hong Kong, the Hakka settlements are the home of indigenous people who have been involved in agriculture and fishing for over 200 years, which has a special place in Hong Kong’s history. However, these settlements are gradually being abandoned as ghost towns due to rapid urbanisation, where the city is progressively constructing high-density habitats to accommodate the exponentially increased population since the 1950s. This challenges designers to rethink means of preserving urban cultural heritage, while engaging in continuous urban regeneration processes. This study investigates workflows to detect historical building styles in one of the most densely-populated cities in the world - Hong Kong - that further deployed in human-computer interfaces in the virtual reality (VR) environment as a collaborative and suggestive design -107958641080

summary	Painterly Expansion: Fields & Flows is a series of intricate topological sculptures crafted through a collaborative design process between an artist and algorithms. With the rise of Artificial Intelligence and multi-agent algorithms utilized in digital design optimization and automation, this research investigates the role of the artist in generative form-making. Painterly Expansion explores the emergent beauty that occurs from the tension between the handcraft of sculpture and algorithmic design processes. This series of work builds upon coded representations of natural systems that form the intricacies of our coral reefs. The algorithm is designed to capture flow and directionality present in aquatic flora and geological formations as seen in Figure 1. The design process operates in real-time where the artist guides, reshapes, and details the sculptures as they take shape. By demonstrating the symbiosis between the artificial and the artist, the sculptures encourage audiences to embrace new ways of thinking and envision a future where technology and human creativity work together.

title	Autonomous Collaborative: Robotic Reconfiguration with Deep Multi-Agent Reinforcement Learning (ACRR+DMARL)

summary	To address the unprecedented challenges of the global climate and housing crises, requires a radical change in the way we conceive, plan, and construct buildings, from static continuous objects to adaptive eco-systems of reconfigurable parts. Living systems in nature demonstrate extraordinary scalable efficiencies in adaptive construction with simple flexible parts made from sustainable materials. The interdisciplinary field of collec- tive robotic construction (CRC) inspired by natural builders has begun to demonstrate potential for scalable, adaptive, resilient, and low-cost solutions for building construc- tion with simple robots. Yet, to explore the opportunities inspired by natural systems, CRC systems must be developed utilizing artificial intelligence for collaborative and adaptive construction, which has yet to be explored. Autonomous Collaborative Robotic Reconfiguration (ACRR) is a robotic material system with an adaptive lifecycle trained with deep, multi-agent reinforcement learning (DMARL) for collaborative reconfigura- tion. Autonomous Collaborative Robotic Reconfiguration is implemented through three interrelated components codesigned in relation to each other: 1) a reconfigurable robotic material system; 2) a cyber-physical simulation, sensing, and control system; and 3) a framework for collaborative robotic intelligence with DMARL. The integration of the CRC system with bidirectional cyber-physical control and collaborative intelligence enables ACRR to operate as a scalable and adaptive architectural eco-system. It has the potential not only to transform how we design and build architecture, but to fundamentally change our relationship to the built environment moving from automated toward autonomous construction.
