Fuzzy Logic Control for an Autonomous Underwater Crawler Available to Purchase

Current underwater crawling vehicles could benefit by using rotating head sonar data to avoid collisions with obstacles. We have developed and optimized a fuzzy logic controller using software for simulation of an underwater environment. The optimization results show near an order of magnitude increase in performance over both straight line and lawnmower search patterns with relatively small changes in the system parameters. The fuzzy logic controller has the capability of navigating a crawler safely and quickly between mission specific points.
