Abstract:

Many people with disabilities can benefit from traditional, manual wheelchairs. A lot of research has been done on computer-controlled chairs with sensors and intelligent control. To decrease the amount of human interaction, algorithms were used. We show the design of a smart, motorised, voice-controlled wheelchair for physically challenged people using an embedded system. The proposed design features a manual voice activation mechanism for physically challenged users. Arduino and a voice recognition processor power the wheelchair. The wheelchair will travel in the direction specified by the microcontroller controls. This can also be controlled with voice commands. To assist persons with both upper and lower limb constraints, a voice-controlled wheelchair prototype was built utilising a commercially available manual wheelchair. The spoken instruction from the speech recognition module is processed by an Arduino microcontroller, which controls the wheelchair's motor movement. A Bluetooth module was also employed to avoid needless wire, and the prototype design included an optional joystick command. The wheelchair recognised spoken directions in English, Chinese, and Malay with high accuracy
