This paper describes the implementation of a discrete in situ construction process using a location-aware mobile robot. An undulating dry brick wall is semi-autonomously fabricated in a laboratory environment set up to mimic a construction site. On the basis of this experiment, the following generic functionalities of the mobile robot and its devel...
Conference Paper
Full-text available
Digital fabrication with concrete has become a highly interesting topic due to the potential for freeform architecture and efficient material placement, with major strides in its development taking place in the past few years. However, reinforcement remains problematic, as current technologies rely mostly on post-hoc placement and infill. In this p...
Conference Paper
Full-text available
Despite the recent advances in, and the adoption of robotic technologies in the construction industry, the architectural processes which demand a high degree of geometric freedom still remain largely labour intensive and manual. This is due to the inherent difficulties in robotizing the current implementation of such processes coupled with the lack...

This paper presents the concept of an In situ Fabricator, a mobile robot intended for on-site manufacturing, assembly and digital fabrication. We present an overview of a prototype system, its capabilities, and highlight the importance of high-performance control, estimation and planning algorithms for achieving desired construction goals. Next, we...
Article
Full-text available
This research investigates the potential of additive manufacturing and digital planning tools for the creation of location-specific façade redesigns that can host cavity-dependent animal species and develops methods for their realization. The proposed approach is explored based on a case study of a student dormitory in need of renovation in the urb...

Die globalen Herausforderungen unserer Zeit sind der Klimawandel, das Bevölkerungswachstum und die Reduzierung des Ressourcenverbrauchs. Für das Bauwesen bedeutet dies, in den kommenden Jahrzehnten mehr zu bauen und gleichzeitig den Ressourcenverbrauch zu verringern und weniger Emissionen auszustoßen. Die handwerklich organisierte Bauindustrie ist...
Chapter
Research on mobile Augmented Reality (AR) technologies has proven many potentials and benefits for assisting craftspeople in various building applications within the AEC domain. However, little research has been done on the use of multi-user mobile AR systems coordinating several people at the same time. This paper examines the potentials of a coll...
Article
In situ Additive Manufacturing (AM) has developed into an active research and industry-transfer area, mainly due to the increasing need for productive and sustainable methods in the concrete construction industry in combination with novel technological enablers. While current systems for in situ AM are often single large-scale stationary facilities...
Chapter
The in situ production of concrete building components with Additive Manufacturing (AM) provides new possibilities in design and function. Current deployable solutions are often stationary gantry systems, which need to increase in size with the constructed object. This research aims to address this issue by using mobile robotic systems for in situ...
Article
Full-text available
In contrast to stationary systems, mobile robots have an arbitrarily expandable workspace. As a result, the spatial dimensioning of the task to be mastered plays only a subordinate role and can be scaled as desired. For the construction industry in particular, which requires the handling and production of substantial components, mobile robots mean...
Article
Full-text available
In the context of dense urban environments and climate change, pedestrians’ thermal experience plays an increasingly significant role in people’s health and well-being. In this research, the authors combine the fields of architecture, climate-responsive design, and robotic fabrication with the goal of investigating strategies to improve outdoor the...
Conference Paper
Full-text available
As a next step in development of Additive Manufacturing (AM) processes, mobile systems can be introduced for construction on site. Mobile AM systems provide the potential for parallelization of tasks and cooperative processes, where multiple systems work together on single tasks. These mobile systems are complex developments that require expertise...
Article
The building industry is one of the least digitalised sectors of the global economy to date. Unlike other industrial sectors, the manufacturing of buildings is characterised by traditional handicraft techniques and individualised construction processes. Digital production technologies from other industrial sectors have not become established in the...
Conference Paper
Full-text available
Building envelopes incorporate a multitude of functions, such as structure, room enclosure, insulation, and aesthetic appeal, typically resulting in multi-material layered constructions. With the technology of additive manufacturing, geometrical freedom can instead be utilised to integrate functional requirements into mono-material building compone...
Preprint
Full-text available
In digital design-to-fabrication workflows in architecture, in which digitally controlled machines perform complex fabrication tasks, all design decisions are typically made before production. In such processes, the formal definition of the final shape is explicitly inscribed into the design model by means of corresponding step-by-step machine inst...

de Die Bauwirtschaft stellt eine der bislang am wenigsten digitalisierten Branche dar. Im Unterschied zu anderen Produktionsbereichen ist die Herstellung von Gebäuden durch individualisierte Bauprozesse gekennzeichnet. Digitale Fertigungstechniken anderer Wirtschaftszweige haben sich im Bauwesen nicht durchgesetzt, da sie nicht die notwendige Indiv...

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 brick...

This paper describes the making of DFAB HOUSE, a multi-technology demonstrator of digital fabrication in architecture, engineering and construction (AEC). While most individual digital fabrication technologies used to build DFAB HOUSE have been presented independently at conferences and in journal articles, this paper describes how, in concert, the...

full-text view-only version: https://rdcu.be/bQKlB The development of novel robotic fabrication technologies in architecture concentrates largely on integrating stationary industrial-type robots into off-site prefabrication processes. By contrast, few enabling robotic technologies exist today that allow robotic fabrication processes to be mobile...
Conference Paper
Full-text available
This research paper presents a novel method for robotic spraying of glass-fibre reinforced concrete (GFRC) on a permeable reinforcement mesh. In this process, the mesh acts as a functional formwork during the concrete spraying process and as reinforcement once the concrete is cured, with the goal of producing slender reinforced concrete elements ef...
Article
While a consensus exists that advanced digital and mechatronic technology is on the cusp of profoundly impacting virtually every manufacturing and industry sector, there are some industries that seem to have profited far less from this ongoing ‘revolution’. One prominent example of this is the construction sector and, in particular, building constr...

In this paper interactive manipulation procedures with CNC machines based on algorithmic design methods are discussed and illustrated by means of a practical example. In conventional CNC aided workflows that lead from virtual models to physical ones, all design decisions must be made beforehand. The production processes are linear and inflexible, t...
