(57) Abstract :
Most of the conventional wheelchairs use the joystick as the user input mode. The drawback of joystick control is that it is not suitable
for physically disabled person who cannot control the movement especially with hands. We presented an voice command activated
power wheelchair whose motion can be controlled by the users voice. It can recognize the users voice and can move according to the
end destination made by the user. To those people who are challenged physically they need to take the entire command either through
manually or joystick of the wheelchair till it reaches the destination. This project is indeed to help the person with disability to move
without external guidance with more automation to the wheelchair. We contributed in enhancing the automation to the system that can
learn all about the locations in a given building, and then take its occupant to a given place in response to a verbal command. Just by
saying go to my room, the wheelchair user would be able to avoid the need for controlling every twist and turn of the route and could
simply sit back and relax as the chair moves from one place to another based on a map stored in its memory. The modules used are
microcontroller hardware (p89v664), IR transmitter and receiver, servo motor interface, ultrasonic obstacle detector, voice recognition
kit. Thus the wheelchair is user-friendly and cost effective.
