K. Vidyasagar, M. Sundarao, M. Sumalatha . MEMS based Wheel Chair for Physically Challenged Persons. Communications on Applied Electronics. 2, 4 ( July 2015), 19-23. DOI=10.5120/cae2015651732
With the advancement of science and Technology an innovative mechanism is adopted to provide the assistance for physically challenged personalities. Spinal card injury persons and physically challenged persons required human assistance to move from one point to another point. Electronics interfaced Wheel chair had designed to move without any assistance. Micro Elelctro Mechanical Systems (MEMS) based accelerometer sensor is used to direct the movement of the device. The wheel chair may move forward, backward, left and right directions based on the output signal of the MEMS device. Two ‘Jonson’ geared motors are attached to the geared sector assembly. PIC16F72 micro controller is used to release the appropriate signals to the motor driving circuit. The developed wheel chair is best suited to meet the challenges of the physically challenges personalities.
