  • Soft Office: a human–robot collaborative system for adaptive spatial
           configuration
    • Abstract: The Soft Office project was developed in response to the rapidly changing context of commercial architecture, where accommodating fluid programmatic requirements of occupants has become key to sustainable interior space. The project is placed within a broader context of relevant research in architectural robotics, in situ robotic fabrication, and adaptive and reconfigurable architecture. It establishes a methodology for spatial configuration through the implementation of a custom collaborative robotic interior reconfiguration system. Within this system, human users and task-specific robots perform complementary tasks toward a dynamic spatial goal that is defined by a set of evaluative criteria intended to predict successful interior space configurations (Bailey et al. in Humanizing digital reality: design modeling symposium Paris 2017, Springer Singapore, Singapore, pp 337–348, 2018). Venturing beyond robotics as merely a means of construction automation, the presented research deploys an approach that critically engages future models of interaction between humans and robotic architecture, mediated by in situ, architecturally embedded machines. In contrast to a conventional collaborative robotic manufacturing process, where a human worker is executing fabrication and manufacturing tasks according to a pre-designed blueprint, the proposed approach engages the human user as the designer, the worker, and the consumer of the architectural outcome. This gives the occupant the agency to rapidly reconfigure their environment in response to changing programmatic needs as well as the ability to respond ad hoc to outside forces, such as social distancing requirements for the post-quarantine re-occupation of buildings. Furthermore, task-specificity of the presented robotic system allows us to speculate on future roles of designers in the development of architectural fabrication technology beyond the appropriation of existing hardware and to look towards systems that are architecture specific.

  • Material characterization of workability and process imaging for robotic
           concrete finishing
    • Abstract: In this paper, we discuss a robotic-assisted concrete finishing method for fabricating architectural panels. Concrete finishing is an important process for producing architectural elements with acceptable surface quality. It is also a challenging process conventionally relying on skillful laborers. We describe a hybrid framework incorporating both human skill and robotics in the concrete finishing process and a multi-phase sensing strategy to assist in part touch-up and to validate final surface quality. The paper discusses a general approach to finishing from three perspectives: (1) Material characterization of concrete’s workability throughout its setting process, (2) A modular system-architecture for collaborative human-robot concrete finishing, and (3) Assessment feedback of surface quality using process images.

  • Cartesian coordinate control for teleoperated construction machines
    • Abstract: Despite the continuous development of the hardware, most construction machines are exclusively teleoperated limiting the control to a single paradigm. The operators usually have to move different joints of the machine in a coordinated way solely relied on their experiences leading to reduced local accuracy and work efficiency. Automation of construction machinery can open up new possibilities to improve efficiency and safety during the construction process. This work introduces a generic method that can adapt construction machines that have been already used in the field for decades, so that a more intuitive and versatile control paradigm can be allowed. We introduce the system architecture with the necessary hardware extension and the closed-loop inverse kinematic based motion controller implemented in a visual programming environment. In contrast to existing works, which are mostly based on developing entirely new systems, an autonomous machine suited for construction sites and other hazardous environments can be obtained at a reduced effort. Because of its low cost and generality, this approach can be widely utilized in construction industries opening possibilities for a combination of the advanced robotics technology with proven machines from construction sites. We present our first prototype system based on a BROKK 170 demolition machine and highlight its capabilities but also the inherent limitations of the proposed method.

  • The geometry of air: large-scale multi-colour robotic additive fabrication
           for air-diffusion systems
    • Abstract: This research investigates the integrated design, robotic fabrication and materialisation of novel air-diffusion systems for contemporary office environments. Specifically, the research focuses on the integration of computational design, multi-objective optimisation and the development of novel approaches and techniques for large-scale 3D-printed module systems for low-embodied energy air ducts in the context of a pilot study for an open office environment. By investigating the interrelationship of polymer extrusion, material behaviour, computational design, computational fluid dynamic (CFD) simulation and multi-objective optimisation, the research leverages the capacities of each of these methods to create highly detailed geometries that are optimised for air diffusion to create locally differentiated thermal comfort. The paper contributes to and further extends existing research in the domain of large-scale 3D printing by presenting a series of developed novel approaches and techniques combining the diverse methods above to address the plural performance demands of low-embodied energy air-diffusion systems. It presents empirical research towards air simulation, geometry optimisation and bespoke fabrication for a high-quality, customised and resilient air-diffusion system to support the flexibility of contemporary office environments and reduce the adverse per capita environmental impact of cities through increased resource-use efficiency and substantial waste and embodied energy reduction.

  • Fabrication grammars: bridging design and robotics to control emergent
           material expressions
    • Abstract: Designers physically engage with a material to experience how certain characteristics allow the fabrication of unique expressions. In digital fabrication, however, this improvisational negotiation is typically replaced by a virtual simulation that predicts how a material expression can be fabricated, limiting the resulting design language to algorithmic forms. In contrast, we believe that digital fabrication can also produce ‘emergent’ material expressions that are so confounded that they appear slightly differently even when being produced by identical operations. This paper argues that such expressions can be executed by a domain-driven feedback paradigm, which integrates a human-in-the-loop to encode the tacit fabrication knowledge that is generated by reviewing intermediate outcomes. We encode this tacit knowledge by fabrication grammars, rule-based descriptions that causally relate fabrication parameters to qualitative descriptions of material expressions. By documenting a set of Single Point Incremental Forming experiments, this paper demonstrates how emergent material expressions can be controlled by semantically meaningful fabrication grammars, which even can be combined towards purposeful design goals. We believe our findings might allow the digital fabrication of material expressions that appear to have been produced manually or naturally; and support the future sharing of tacit fabrication knowledge.

  • Oscillating wire cutting and robotic assembly of bespoke acoustic tile
           systems
    • Abstract: New methods of manufacturing and assembly, enabled through robotic fabrication, push the boundaries of the conventional in architecture and construction, when coupled with advanced digital design and simulation. This paper presents a novel method for digital production of bespoke ceramic assemblies for spatial acoustic modulation, demonstrating a hybrid robotic process combining robotic oscillating wire cutting (ROWC) of wet clay bricks and adaptive pick and place (APnP) production of bespoke brick panel assemblies. These processes are carried out within the framework of a deployable robot cell that can be shipped to a jobsite where complex fabrication and assembly can be performed in situ. The research bridges the gap between serialized and bespoke production of architectural elements, by minimally disrupting existing production chains as a viable way forward to integrate digital technologies into existing manufacturing and construction processes. The proposed methods are demonstrated through a collaboration with brick producer Strøjer Tegl leading to the manufacturing and assembly of a full-scale acoustic demonstrator of 9 × 4 m, comprises 2200 bricks with 14 shape variants.

  • Design, simulation and robotic assembly of reversible timber structures
    • Abstract: Wood is more and more seen as a sustainable solution to offset carbon emissions from constructions. In response and in parallel to this, the research in robotic timber construction is evolving rapidly, pushed by Industry 4.0 technologies and the integration of digital and physical robotic assets. This paper presents an approach for the design and assembly automation of layered timber structures, with the use of a flexible cell based on collaborative robots. Advanced assembly procedures and digital design of non-standard timber structures are here established and integrated. The automation process is here enhanced by the (1) use of feedback systems based on the location and force signals, (2) the introduction of a flexible robot setup with automatic screwing, and (3) human-collaboration to provide immediate assistance to the robot in the case the signals do not match the defined assembly conditions. The paper discusses the development and use of a Cyber-Physical System to govern the entire construction process, including reflections on the integrated approach to the design, modelling and simulation of the process.

  • Adaptive kinematic textile architecture
    • Abstract: The research presented in this paper explores how textiles can be formed into adaptive, kinematic spaces to be able to respond to its environment and users utilizing on-site, distributed, mobile robotic connectors. The project aimed at creating an adaptive system that consumes little energy while making use of textiles’ advantageous qualities—their lightweight, portability, and manipulability. This was achieved through the development of a bespoke on-material mobile machine able to locomote on suspended sheets of fabrics while shaping them. Together, the connector and the tectonic system compose a lightweight architectural robot controlled with a feedback loop that evaluates real-time environmental sensor data from the space against user-defined targets. This research demonstrates how the combination of mobile robotics and textile architecture opens up new design possibilities for adaptive spaces by proposing a system that is able to generate a significant architectural effect with minimal mechanical actuation.

  • Skeletal composites: robotic fabrication processes for lightweight
           multi-nodal structural components
    • Abstract: The research presented in this chapter describes the novel robotic fabrication strategies for multi-nodal structural components made from lightweight fiber composite materials. The paper contextualizes the research within a larger area of composite manufacturing in architecture and focuses on the developed methodologies for adaptive, material-efficient production. This research builds on coreless filament winding processes that eliminate the need for large surface molds and wasted materials for composite production. This process allows for large geometrically differentiated structural building components to be easily produced adaptively for architectural applications. The research tests the production of complex components for a vertical lattice structural system. The multi-nodal structural components enable continuous material and fiber orientations across the intersections of the lattice while simplifying connections. Key improvements presented in this paper included the robotic assembly process for the reconfigurable winding frames that reduce assembly times and increase accuracy, computational techniques for developing winding syntax, and physical simulation of material orientations for robotic path planning. This is followed by a conclusion and outlook to discuss the tested results on a full-scale demonstrator and the future design potentials.

  • The digitization of the automated steel construction through the
           application of microcontrollers and MQTT
    • Abstract: Data acquisition and transfer are crucial aspects of the digitization and automation of construction workflows. Through the integration of microcontrollers in machinery, a multitude of data can be acquired and analyzed to adapt fabrication processes and optimize performance. The goal of this research was to develop connected multi-functional robotic systems that can transfer data across a wireless network through MQTT, a robust and lightweight IoT communication protocol. This research demonstrates a use case for such interconnected robotic technology by establishing wireless communication through MQTT between a mobile robot and a plasma cutting station. A microcontroller was utilized in the digitization and automation of this steel construction process to obtain, process and transfer the data in a way that was monitorable and storable for managing and optimizing workflows.

  • Crafting plaster through continuous mobile robotic fabrication on-site
    • Abstract: Industrialization of architectural components and technological advances have had a significant impact on how we design and build. These developments, resulting in mass-produced and panelized architectural components, have rationalized building construction. However, they often do not reveal the true potential of the inherent qualities of malleable materials. This research investigates the bespoke design potentials of combining a cementitious plaster, with a robotic spraying and forming process, and proposes an adaptive thin-layer additive manufacturing method for plasterwork. Research goals address an on-site construction system that is capable of performing continuous robotic plaster spraying on building elements. To support the understanding of the complex-to-simulate material behavior in this process, systematic studies and physical testing are proposed to be conducted to collect empirical knowledge and data. The goal is to explore bespoke surface qualities, with minimal waste, moving away from the modular and standardized form of the material. The paper presents the preliminary results and findings of the method that aims addressing the challenge of an adaptive construction system capable of performing continuous fabrication, for which mobile robots are proposed to be deployed.

  • Robotic timber assembly
    • Abstract: This paper presents an efficient workflow for the established digital fabrication and robotic assembly of a discrete timber structure. Here, the complexity and aesthetic value of the structure are derived from the aggregation and assembly of similar parts. In limiting the architectural building blocks to a few similar pieces, specific assembly is freed, and infinite structures can be constructed through iteration with the same sequential logic. Fabrication of the individual pieces is simplified, reducing material and energy use through standardization of component parts. The research further examines the potential of how three-dimensional wooden joinery can be incorporated to work with the robotic assembly, not only by analyzing the use of industrial robotic arms with an intent to leverage their capabilities, but also by exploring their limitations. In establishing a workflow around a joint which requires no adhesives or fasteners, the ability to robotically disassemble and reassemble the structures infinitely in different ways maximizes structural potential and material reuse. The assembly and aggregation of these joineries demonstrate a prototype that can be adopted for future timber constructions.

  • Craft to site
    • Abstract: The paper presents a craft-oriented middleware for assisting in situ robotic fabrication. This middleware addresses the need for sensor-based feedback in robotic fabrication involving uncertain materials, non-structured environments, or post-production surfaces. The presented middleware addresses these fabrication challenges by allowing the robot to react to its environment without the need for a predetermined program. The middleware and its components are presented, followed by experiments demonstrating in situ capacities. The first experiment demonstrates autonomous carving—performing an iterative, non-prescribed robotic fabrication process. The second experiment presents integrated fabrication—a sequence of subtractive and additive techniques performed on a non-even substrate. Together, these experiments contribute to the implementation of sensible robotic middleware in architecture and assist in restoring the lost link between workmanship and construction sites.

  • Towards digital automation flexibility in large-scale timber construction:
           integrative robotic prefabrication and co-design of the BUGA Wood Pavilion
           
    • Abstract: This paper discusses the digital automation workflows and co-design methods that made possible the comprehensive robotic prefabrication of the BUGA Wood Pavilion—a large-scale production case study of robotic timber construction. Latest research in architectural robotics often focuses on the advancement of singular aspects of integrated digital fabrication and computational design techniques. Few researchers discuss how a multitude of different robotic processes can come together into seamless, collaborative robotic fabrication workflows and how a high level of interaction within larger teams of computational design and robotic fabrication experts can be achieved. It will be increasingly important to discuss suitable methods for the management of robotics and computational design in construction for the successful implementation of robotic fabrication systems in the context of the industry. We present here how a co-design approach enabled the organization of computational design decisions in reciprocal feedback with the fabrication planning, simulation and robotic code generation. We demonstrate how this approach can implement direct and curated reciprocal feedback between all planning domains—paving the way for fast-paced integrative project development. Furthermore, we discuss how the modularization of computational routines simplify the management and computational control of complex robotic construction efforts on a per-project basis and open the door for the flexible reutilization of developed digital technologies across projects and building systems.

  • Robotic vault: a cooperative robotic assembly method for brick vault
           construction
    • Abstract: Geometrically complex masonry structures built with traditional techniques typically require either temporary scaffolding or skilled masons. This paper presents a novel fabrication process for the assembly of full-scale masonry vaults without the use of falsework. The fabrication method is based on a cooperative assembly approach in which two robots alternate between placement and support to first build a stable central arch. Subsequently, the construction is continued individually by the robots - building out from the central arch based on an interlocking diagonal brick sequence. This proposed method is validated through its successful implementation in a full-scale vault structure consisting of 256 glass and concrete standardized bricks. The paper includes strategies for developing the design, sequencing, and robotic assembly methods used to build the vault.

  • Interactive design to fabrication, immersive visualization and automation
           in construction
    • Abstract: The presented research showcases a custom design-to-fabrication workflow leveraging virtual reality (VR), augmented reality (AR), and automated robotic fabrication. The process and custom platform demonstrate how these technologies can work together to create intuitive direct-to-fabrication workflows for the design and construction industry. The main focus of the research is developed in four different stages corresponding to the workflow. In stage one, a custom VR platform provides users an intuitive design space in full scale while accounting for fabrication constraints. Second, the modelled information is translated through a cloud -based service into 3d modeling software, in real time. In the third stage, within the 3d modeling software, a custom software solution calculates the required notching for the construction system while aligning assembly order to fabrication order. Through this platform, the programming data for robotic milling and pick-and-place operations is generated, and fabrication through industrial robotic arms is enabled. Fourth, using QR codes on fabricated components, an AR overlay aids in constructing the designed demonstrator, keeping track of pieces, and providing the right assembly order.

  • The smart robot crafting approach to computing materials
    • Abstract: This study presents a universal method that combines robotic/mechanical automation with image processing and artificial intelligence (AI) to generate material models without any pre-existing knowledge of the material itself. Inspired by the “hand-eye-mind” process, used typically in designing and crafting, this study proposed a digital version of the process that is capable of automatically conducting a large number of material experiments, observing them using image recognition, and subsequently training AI. The proposed method generates neural network models for common digital design environments that help to bridge a wide range of design intentions, fabrication controls, and dynamic material behaviors. In this study, two different experiments were conducted using the same method. The first one generated a material model for the bending behavior of non-linear synthetic rubber, and the other involved the dynamic control of the form-finding process of thermoplastics based on dynamic annealing, which contributed to a new 3D printing method. With current progress, we are able to prove that such a workflow is a widely adaptable method that encompasses a large variety of material properties and fabrication methods. It enables design and construction using complex material behaviors without the support of existing material/structure models.

  • Augmented bricklaying
    • Abstract: Augmented bricklaying explores the manual construction of intricate brickwork through visual augmentation, and applies and validates the concept in a real-scale building project—a fair-faced brickwork facade for a winery in Greece. As shown in previous research, robotic systems have proven to be very suitable to achieve various differentiated brickwork designs with high efficiency but show certain limitations, for example, in regard to spatial freedom or the usage of mortar on site. Hence, this research aims to show that through the use of a craft-specific augmented reality system, the same geometric complexity and precision seen in robotic fabrication can be achieved with an augmented manual process. Towards this aim, a custom-built augmented reality system for in situ construction was established. This process allows bricklayers to not depend on physical templates, and it enables enhanced spatial freedom, preserving and capitalizing on the bricklayer’s craft of mortar handling. In extension to conventional holographic representations seen in current augmented reality fabrication processes that have limited context-awareness and insufficient geometric feedback capabilities, this system is based on an object-based visual–inertial tracking method to achieve dynamic optical guidance for bricklayers with real-time tracking and highly precise 3D registration features in on-site conditions. By integrating findings from the field of human–computer interfaces and human–machine communication, this research establishes, explores, and validates a human–computer interactive fabrication system, in which explicit machine operations and implicit craftsmanship knowledge are combined. In addition to the overall concept, the method of implementation, and the description of the project application, this paper also quantifies process parameters of the applied augmented reality assembly method concerning building accuracy and assembly speed. In the outlook, this paper aims to outline future directions and potential application areas of object-aware augmented reality systems and their implications for architecture and digital fabrication.

  • Autonomous dry stone
    • Abstract: On-site robotic construction not only has the potential to enable architectural assemblies that exceed the size and complexity practical with laboratory-based prefabrication methods, but also offers the opportunity to leverage context-specific, locally sourced materials that are inexpensive, abundant, and low in embodied energy. We introduce a process for constructing dry stone walls in situ, facilitated by a customized autonomous hydraulic excavator. Cabin-mounted LiDAR sensors provide for terrain mapping, stone localization and digitization, and a planning algorithm determines the placement position of each stone. As the properties of the materials are unknown at the beginning of construction, and because error propagation can hinder the efficacy of pre-planned assemblies with non-uniform components, the structure is planned on-the-fly: the desired position of each stone is computed immediately before it is placed, and any settling or unexpected deviations are accounted for. We present the first result of this geometric- and motion-planning process: a 3-m-tall wall composed of 40 stones with an average weight of 760 kg.
