This paper describes theoretical and experimental results using the SmartNav rule-free fuzzy rover navigation system. SmartNav divides the terrain perceived by the rover into a number of circular sectors, and evaluates each sector using goal and safe

Two safety measures for terrain classification are described: safety score and safety grade. The terrain safety score s is a multi-valued quantitative measure in the form of a crisp numeric value in the continuous unit interval [0.0, 1.0], that is, $

The concepts of Local, Regional, and Global Traversability Indices have been introduced recently (Seraji, 1999, 2000, 2001). These indices represent the suitability of a terrain for traversal by a mobile robot at different scales of resolution. This

This paper presents new measures of terrain traversability at short range and long range of a mobile robot; namely, local and global traversability indices. The sensor-based local traversability index is related by a set of linguistic rules to large
