In-situ robotic construction: Extending the digital fabrication chain in architecture

Abstract

In this paper, viable applications are explored for mobile robotic units on construction sites. While elucidating potential aims and requirements for in situ fabrication in the construction sector, the aim of this work is to build upon innovative paradigms of human-machine interaction in order to be able to handle the imprecision and large tolerances commonly faced on construction sites. By combining the precision of machines with human cognitive skills, a simple yet effective mobile fabrication system is experimentally developed for the construction of algorithmically designed additive assemblies that would otherwise be impossible to build using conventional manual methods, because of the sheer number of individual building blocks and the scale of the structure. This new approach for the collaboration of humans and machines—aiming at a fuller integration of human abilities and the advantages and capabilities of digitally controlled machines—will result in advances in the construction industry, opening up new fields of application for architects and designers in the design and realization of buildings.
