Building and Navigation Strategies for On-Site Robotics

Research Project 17-1 (RP 17-1)

IntCDC Research Project 17-1 – Building and Navigation Strategies for On-Site Robotics
BUILDING AND NAVIGATION STRATEGIES FOR ON-SITE ROBOTIC CONSTRUCTION

Building construction typically relies on a centralised design, where information is used to generate the most appropriate sequence of assembly actions, which is assumed to be the unambiguous blueprint for building execution. However, uncertainties in the actions leading to tolerance violations, the true dimensions of the fabricated modules, and changes in the environment can require frequent replanning. The resulting costs can be prohibitive for construction projects that have reached a level of complexity that is increasingly difficult to plan. For similar reasons, on-site assembly is often reduced to purely reactive and manual operating sequences.

The central aim of this research project is to master the increasing complexity of the on-site construction of high-performance building systems through decentralised planning strategies that compute smart assembly sequences based on AI reasoning, thus enabling new processes in the research area of large-scale on-site robotic construction. This research project contributes significantly to the Research Network 2-1 as it is the only project within the Cluster that focuses on high-level planning for building execution.
