Abstract
We present a fuzzy version of the crisp spatial logic developed by Randell et al., which takes the single relation connected-with as primitive. Membership functions are defined for each spatial relation defined in the crisp theory. Furthermore, principles are presented for defining linguistic variables whose linguistic values are spatial relations. The work reported here addresses spatial reasoning in situations where numerical or geometric precision is unlikely; it is particularly suited for dynamic situations. Keywords : Spatial Reasoning, Fuzzy Logic, Ontology, Mereology, Topology, Linguistic Variables, Lattices, Constraints, Qualitative Simulation 1. Introduction Spatial Reasoning is central to several important areas of engineering and computer science, including computer vision, assembly, and especially path planning for mobile robots. Because of the sort of mathematics forming the ubiquitous background of engineers, it is natural that engineers should attempt to represent spa...
