A parallel path planning algorithm for mobile robots

Abstract

This paper presents a path planning algorithm for mobile robots. We introduce a parallel search approach which is based on a regular grid representation of the map. The search is formulated as a cellular automaton by which local inter-cell communication rules are defined. The algorithm is made adaptive by utilising a multiresolution representation of the map. It is implemented on AMT DAP 510, which is a SIMD machine. I.
