PWM Based Android Controlled Wheel Chair
International Journal of Computer Science and Information Technology, 2018 Most of the physically disable individual satisfies their movement through motorized wheelchair. The scenario is unusual for the disables of developing countries because of their economic conditions. Moreover traditional powered wheelchair is not comfortable to all segments of the disable society because of their complexity.
