Spatial Reasoning about Relative Orientation and Distance for Robot Explorationr data is typically imprecise. We propose an approach that propagates orientation and distance intervals to produce global knowledge and compare it with qualitative reasoning calculi in the context of indoor mobile robot exploration. We combine this propagation method with a path-based and predomina

Linearized Terrain: Languages for Silhouette Representationss a profile of a landform seen from a particular observer’s perspective. We develop a terrain language as a formal framework to capture terrain features. The horizon of a terrain silhouette is represented as a string. The alphabet of the terrain language comprises straight-line segments. These line

Maintaining Spatial Relations in an Incremental Diagrammatic Reasonerhitecture represents jointly exhaustive and pairwise disjoint (JEPD) spatial relation sets as nodes in a dependency network. These spatial relation sets include interval relations, relative orientation relations, and connectivity relations, but in theory could include any JEPD spatial relation sets.

“Simplest” Paths: Automated Route Selection for Navigationngth of route. Most automated navigation systems rely on computing the solution to the shortest path problem, and not the problem of finding the “simplest” path. This paper addresses the issue of finding the “simplest” paths through a network, in terms of the instruction complexity. We propose a “si
