This paper presents a type-2 fuzzy logic system that can be applied to a mobile robot which is a project associated with using infrared sensors as distance sensors, DC motor control system, knowledge of multiplex, RS-232 interface line, knowledge of microcontroller and knowledge of intelligent system. Infrared sensors are used to measure distance between a robot and obstacle. The type-2 fuzzy logic controller processes the data output to control the direction of the mobile robot movement. The behavior-based control for mobile robot was designed, which consists of two tasks, obstacle avoidance and corridor following. The results obtained demonstrate the efficiency of type-2 fuzzy logic control system and the ability to solve the problems. The experimental results show better performances than those using on-off and type-1 fuzzy logic controls.
