Rule–based reasoning and neural network perception for safe off–road robot mobility

Abstract: Operational safety and health monitoring are critical matters for autonomous field mobile robots such as planetary rovers operating on challenging terrain. This paper describes relevant rover safety and health issues and presents an approach to maintaining vehicle safety in a mobility and navigation context. The proposed rover safety module is composed of two distinct components: safe attitude (pitch and roll) management and safe traction management. Fuzzy logic approaches to reasoning about safe attitude and … Show more

“…The Traversability Index is used for classifying planetary surfaces and provides a simple means for incorporating the terrain quality data. Moreover, there are also other methods, such as the neural network based architecture [6] and a probabilistic modeling technique for high-speed rough-terrain analysis of outdoor mobile robots [7]. Except for only several methods, like the GESTALT, which has been validated on real planetary environment, many other methods still suffer degradation due to the complex, unstructured terrain and unavoidable uncertainty in measurement, although they are mostly experimentally shown accurate in well-known terrain.…”
