This paper describes the realization of embedded fuzzy control systems for planning the motion of autonomous mobile robots. The development of the controllers is carried out by means of a reconfigurable platform based on FPGAs. This platform combines a general-purpose processor with specific hardware to implement fuzzy inference modules, thus allowing the comparison between a fully software solution and others based on hybrid hardware/software techniques. Both the processing system and the inference modules are configurable using available CAD tools, which make the development of the controllers easier.
