Abstract:
Normally physically disabled people and those who have lost their legs by any accidents or due to malnutrition have a special innovation, wheel chair to give them the pleasure of moving with ease.
The idea of wheel chairs that the innovators have come up with mostly involves the handling of
the equipment physically with their hands. But this is difficult or impossible for the patients who
have lost their hands or aged. With the aim of providing these people an enhanced pleasure of
handling the equipment with comfort, the idea of voice controlled wheel chair has been chosen
and studied upon. This model uses Arduino and voice recognition module which recognizes the
word from the user and matches with the predefined instruction in the system and the sensor
attached to the design checks for any obstacles including pits and then directs the wheel chair to
act accordingly.
A voice controlled wheelchair can provide easy access for physical disabled person who cannot
control their movements especially the hands.
Once the voice recognition system recognizes the voice commands in comparison to the prestored memory, the respective coded digital signals would be sent to Processor which then controls the wheelchair accordingly.
The system is divided into two main components: speech recognition module with voice
Recognition module sensor and wheelchair control unit. Handicapped people do not have soft
motion of hands and legs, it is therefore not easy to control different turns of the wheelchair
manually. To remove this problem moment of wheelchair is controlled by voice. So by giving
simple voice command turns wheelchair to different directions depending on the voice command
given to it.
