Abstract:

This paper presents the current findings of the project JuBot that focuses on integrating assistive humanoid robots in residential environments for seniors. This paper builds on an earlier eCAADe publication and examines how Building Information Models (BIM) can be utilised and enhanced to create a 3D framework that facilitates the simulation and guidance of humanoid robots within buildings. In close collaboration with robotics partners, key requirements and concepts for an IFC-based data structure and schema were identified. While specific details may demand a high level of precision, the aim is to maintain a lean, efficient model that serves as a reference framework for locating objects and information complementing real-time data gathered by the robot on-site. Existing gaps in the current IFC 4.3 schema are revealed, and suggestions for model enhancements are made and demonstrated exemplarily for the object class of door panel, lining and handles. Additionally, new property sets for housing equipment, including a mobility index for furniture items, are introduced. Examining these use cases reveals various potentials that will be evaluated further in subsequent stages of the project. The proposed schema extensions aim to demonstrate that navigation-specific BIM data holds value for the everyday use in assistive systems.
