Local planners are notsufficient and, since tasks often involve changing theenvironment, global planners are limited by time constraints.This paper adopts the notion that pre-processingof the known environment, in order to generate aroadmap, can significantly improve on-line path planningtasks. We present results obtained from an instanceof the Ariadne's clew algorithm for path planningproblems within the steam ...
