Automatic Disability Chair for Lower Limb Disable People

The paper proposes an idea of an electric wheelchair which supports the body movement not only in locomotion but in standing position. Center of gravity is maintained by adjusting the whole body to the center of the base. Thus with the help of the Automatic Disability Chair (ADC) an individual can locomote by using joystick and stand by pressing buttons. A microcontroller (Arduino mega) is integrated with all inputs, motor drives & actuators, that controls all operations of ADC. The wheelchair is supported with an external iron rod and suspension struts to reduce any hustle, additionally rechargeable batteries are employed in ADC. All the quantification and measurements were done before, based on this calculation, a scaled 3D prototype was first developed on AutoCAD and then it was implemented practically.
