“…Candidate questions might reach from sustainability, alternative energy, and adaptation of technology to local environment to moonshot projects, such as devices intended to be used in space exploration missions, in which people participate out of curiosity. A first project on crowd-sourced fabrication [Lafreniere et al, 2016] targeting the collaborative assembly of large structures provides initial insights into the potential of this research area.…”

While fabrication technologies have been in use in industry for several decades, expiring patents have recently allowed the technology to spill over to technology-enthusiastic "makers". The big question now is whether the technology will further progress towards consumers, which would allow the technology to scale from hundreds of thousands of users to hundreds of millions of users. Such a transition would enable consumers to use computing not just to process data, but for physical matter. This holds the promise of democratizing a whole range of fields preoccupied with physical objects, from product design to interior design, to carpentry, and to some areas of mechanical and structural engineering. It would bring massive, disruptive change to these industries and their users. We analyze similar trends in the history of computing that made the transition from industry to consumers, such as desktop publishing and home video editing, and come to the conclusion that such a transition is likely. Our analysis, however, also reveals that any transition to consumers first requires a hardware + software system that embodies the skills and expert knowledge that consumers lack: (1) hardware and materials that allow fabricating the intended objects, (2) software that embodies domain knowledge, (3) software that embodies the know-how required to operate the machinery, and (4) software that provides immediate feedback and supports interactive exploration. At the same time, sustained success will only be possible if we also consider future implications, in particular (5) sustainability and (6) intellectual property. We argue that researchers in HCI and computer graphics are well equipped for tackling these six challenges. We survey the already existing work and derive an actionable research agenda.

“…Most importantly, this lack includes limited context-awareness with no feedback, insufficient localization accuracy to guide construction tasks, as well as the inability to register and measure the as-built structure with sub-centimeter accuracy. Additionally, a custom craft-specific user interface for fabrication is rarely developed even though most off-the-shelve augmented systems include the possibilities for such functionalities in their application programming interfaces (API) (Lafreniere et al 2016). track and estimate the location of the objects (for technical details and implementation, refer to Sandy and Buchli 2018).…”

“…However, the challenge of digital fabrication on a building scale is not merely the full automation of single tasks. Recently, a stream of research has emerged in architecture, recognizing the high diversity of tasks associated with the domain of architecture and construction (Vasey et al 2016). This stream foresees a digital building construction methodology, where skilled workers and machines will share diverse tasks in the same work environment and collaborate towards common goals, combining the best of both their strengths and still fully exploiting a digital design-to-production-workflow (Stock et al 2018).…”

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.

“…It has already been demonstrated in previous work that well designed human-machine interfaces (HMIs) and background computational coordination have potential for coordinating multiple users in complex building processes; within HMI research just-in-time instructions provided through wearable devices could provide the necessary instructions for non-expert users to engage successfully with robots towards the production and assembly of architecture-scale structures [13].…”

In this paper, we present a set of enabling technologies developed for the KUKA Innovation Award to facilitate Human Robot collaboration targeted for the architecture, engineering and construction (AEC) sector. Critically, little progress has been made in the usability of user interfaces for industrial robots [1]. We targeted our investigation explicitly towards human-robot collaboration (HRC) in wood based prefabrication production. Although wood is a sustainable material with abundant processing possibilities, it is also a material system where process knowledge remains critically important, making highly automated workflows unfeasible and inefficient. We propose an interactive fabrication process where a user such as a construction worker could wear an augmented reality head mounted display (ARHMD) as an interface to plan robotic trajectories, influence production sequencing, and view superimposed diagnostic feedback. We describe necessary system components including a robotic workcell consisting of a KUKA LBR iiwa, flexFELLOW mobile platform, a Robotiq 2-finger gripper and a custom platform and material feeding station. In addition, we describe a communication framework and set of protocols connecting a CAD digital design environment, a user interface (UI) for Microsoft HoloLens, a ROS server for backend path planning and coordination, and a 3D graphical web interface for downstream visualization of construction status. We conclude with an outlook on enabling technologies for human-robot collaboration in construction, and the importance of increasing digital integration and accessibility in characteristic production workflows through accessible and intuitive digital interfaces.
