Paper Abstract
In this paper, we have primarily discussed technical challenges and navigational skill requirements of mobile robots for
traversability path planning in natural terrain environments similar to Mars surface terrains. We have described different
methods for detection of salient terrain features based on imaging texture analysis techniques. We have also presented
three competing techniques for terrain traversability assessment of mobile robots navigating in unstructured natural terrain
environments. These three techniques include: a rule-based terrain classifier, a neural network-based terrain classifier, and
a fuzzy-logic terrain classifier. Each proposed terrain classifier divides a region of natural terrain into finite sub-terrain
regions and classifies terrain condition exclusively within each sub-terrain region based on terrain visual clues. The
Kalman Filtering technique is applied for aggregative fusion of sub-terrain assessment results. The last two terrain
classifiers are shown to have remarkable capability for terrain traversability assessment of natural terrains. We have
conducted a comparative performance evaluation of all three terrain classifiers and presented the results in this paper.
