Smart wheelchair using fuzzy inference system

In this paper “Smart Wheelchair using Fuzzy Inference System” has been presented, which has a user friendly guidance system and has ability to avoid obstacles. For guiding the wheelchair Finger Tip Control is used and for obstacle avoidance Ultrasonic Sensors have been used. The fuzzy If-Then rules have been defined which govern the functioning of the wheelchair in different conditions. The system is simulated on fuzzy tool box and results have been generated. The use of fuzzy control allows the use of inexpensive and imprecise sensors, which will keep the overall system cost and complexity low. Using fuzzy logic control makes the implementation of the system much more practical which is the number one goal.
