Design and Fabrication of Automated Wheelchair

Abstract

Wheelchairs are used by people to whom walking is difficult or impossible due to illness, injury or disability. Driving a manual wheelchair or crutches is a difficult task and past invented automatic wheelchair are not available in present market that can be bought and used for physically disable persons. The purpose of this research work is to propose of an automated wheelchair system which facilitates the users. The proposed wheelchair has been implemented with design, simulation and construction of the whole body. Automated Wheel Chair assists disabled people to become more mobile and independent. The main objective of this project is to design and fabricate a cheap, intuitive and practical automated wheelchair. Many of the disabled persons uses hand powered wheelchair who do not have the physical strength or coordination to propel themselves on the tricycle with their arms and hands. This automated wheelchair has the potential to deliver increased freedom to a considerable consumer base. The proposed system presents a user friendly tricycle which can be easily assembled to the wheelchair at any time. It has front wheel propelled mechanism with hub motor installed inside the wheel. The controller is the brain of the automated wheelchair, controlling the motor speed, start, stop. As it is connected to all other electronic parts such as battery, motor, and the throttle, display (battery indicator). The disabled people who use a normal wheelchair for mobility and navigation requires an another person for support and to move around. Mobility of disabled people is concerned social issue nowadays. Here comes the need of an automated wheelchair, which adds on power to the manual wheelchair with its user friendly tricycle.
