We propose an approach to the design hierarchical behaviors for mobile robot navigation in which robot perceives information about the environment from sensor then computes fuzzy output for individual behavior. Each behavior involves a fuzzy controller with the same output. The behavior hierarchy combines commands from fuzzy behavior output and defuzzifies it to archive crisp values for controlling the direction in which robot moves. Simulation results and statistics demonstrate the feasibility of our proposal.
