Voice Operated Wheelchair For Disable Person
Project Abstract / Summary : The project aims at controlling a wheelchair by means of human voice. It enables a disabled person to move around independently, using a voice recognition application which is interfaced with motors. The prototype of the wheelchair is built using a micro-controller, chosen for its low cost, in addition to its versatility and performance in mathematical operations and communication with other electronic devices. The system has been designed and implemented in a cost effective way so that if our project is commercialized the needy users in developing countries will benefit from it.
Why did you choose to work on this project topic : The number of people who need to move around with the help of some artificial means, whether through an illness or an accident is continually increasing. With the help of advantages of technological evolution, we have obtained a wheelchair which can be driven with using voice commands.Most of the conventional electric powered wheelchairs are using joystick as a used input mode of control to maneuver the powered wheelchairs.
The drawback of joystick control is that it is not suitable for physical disabled person who cannot control their movements especially the hands. The proposed voice-activated powered wheelchair supplementary with joystick control allows physically disabled person to maneuver the wheelchair easily without the need to use hands. The propelling of the powered wheelchair depends on the motor control and drive system and Infineon DC chopper power module .Once the voice recognition system recognizes the voice commands in comparison to the pre-stored memory, the respective coded digital signals would be sent to the microcontroller which then controls the wheelchair accordingly
We have also use ultrasonic module if any object arrive in front of wheelchair it will automatically stop so there are many feature of this wheelchair and we will add some new feature in future development.
