Abstract
Controlling an Indoor Autonomous Mobile Robot (IAMR) requires an information system that describes its spatial environment. In order to model geometric and topological information, we propose an object-oriented representation model, linked to a structural model composed of hypergraphs that describe the spatial structure of each composite object.
To avoid inconsistencies when updating the model we use a constraint-satisfaction control mechanism. The integration of the ATMS (Assumption-Based Truth Maintenance System) reasoning mechanism allows us to identify the causes of violated or unsatisfied constraints.
