Design and Implementation of Smart Wheelchair with Advanced Control Interfaces

Abstract

As wheelchair users demand support and assistance from others in order to travel, the study intends to assist physically impaired persons with their mobility, particularly those who have lost their capacity to use their legs due to paralysis, an accident, or old age, as well as those who have feeling issues. The proposed project would provide wheelchair users with location-based services using one-finger control, voice control, and GPS tracking. In comparison to the expensive imported wheelchairs now on the market, the technology will be more affordable and user-friendly. With the support of a user command, the intelligent wheelchair gadgets will be able to maneuver themselves. Users will exert less effort because to the effortless mobility. The project will primarily use an E-bike motor and motor driver, an Arduino, a GPS module, and a solar panel. The voice control signal and manual control utilizing a joystick are used by the motor driver to operate. The Arduino includes a voice-activated device for physically challenged persons who are unable to control their hand motions. Family members will be able to trace the precise position in the case of emergencies due to the usage of GPS. The system will use a solar panel in addition to it to charge the battery. As an additional security measure, an emergency power OFF (EPO) switch is included. This switch is intended to turn the system off in an emergency or when it cannot be switched off normally. Using Porteous, the project simulation is carried out.
