An intelligent wheelchair is designed to help physically disabled patients by using speech recognition system to control the movement of wheelchair in different directions. Automatic obstacle detection is done using an ultrasonic sonar system which helps the patient to apply a momentary brake in case any obstacle suddenly comes in the way of the wheelchair and also vocally inform patient about obstacle distance from wheelchair. The intelligent wheelchair is designed in such a way that it can be controlled easily with minimum effort from the patient and also provides protection from obstacle collision if any voice mistake happens. The extra features like voice search and news listening mode is also available. The leading improvement is the low cost design and more features which allows more number of patients to use this wheelchair.
