A wheelchair is a wheeled mobility device in which the user sits. The device is propelled either manually (by turning the wheels by the hand) or via various automated systems. Wheelchairs are used by people who is having difficulty to walk due to illness (physiological or physical), injury, or disability. In this project, the wheelchair is equipped with voice control or recognition module. The user can instruct the wheelchair through the voice recognition module(VRM) to move forward, backward, left or right. Ultrasonic sensor also is added to sense any obstruction. The project scope will be used recognition module to move wheelchair to right, left, forward or backward direction, to use ultrasonic sensor to detect any obstacle, to design motor driving circuit, to design power supply for each module in the system and to troubleshoot the circuit should any problem arise. For this project, the voice controlled wheelchair is used voice recognition to control the wheelchair direction movement A sensor is used to detect any barrier to make the wheelchair safe and reliable. The expected outcome of this project is the wheelchair direction movement can be controlled by voices whether the wheelchair goes to the right, left, fmward or backward direction. An additional sensor is included to sense any incoming banier during the wheelchair movement.
