The goal of the research project “In situ Fabricator” is to bring robotic fabrication out of the laboratory environment directly onto construction sites. We believe that the high-accuracy fabrication of large-scale building structures through controlled manipulation beyond structured factory settings, using context aware mobile robots, could significantly expand the application space of automated building construction in architecture.
This video 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 lab environment set up to mimic a construction site. With this experiment the following generic functionalities of the mobile robot and its developed software for mobile in situ robotic construction are demonstrated: 1) its localization capabilities using solely on-board sensor equipment and computing, 2) its capability to assemble building components accurately in space ? including the ability to align the structure with existing components on site, and 3) the adaptability of computational models to dimensional tolerances as well as to process-related uncertainties during construction.
