Wheelchairs for Disabled Control by Microcontroller System

Abstract

This research aimed to design and construction a wheelchair for disabled people with microcontroller system, and to test the efficiency from the tools created. The instrument used in the research consisted of joystick accessories set, in the control the driven system the direction of the motor is driven by the front-back, turn left, turn right and stop. And the microcontroller system is the controller that drives the motor in the signal transmission value of the pulse width modulation (PWM).

          The study tested the effectiveness of horizontal movement speed, found that in the distance of 50 meters at the weight of 90 kg, take time was 1.26 minutes. And the test result of the wheelchair movement speed of wheelchair for disabled people rising on a 10-degree slope, found that the distance of 50 meters at a weight of 90 kg, take time was 2.07 minutes. And the satisfaction survey results of wheelchair users for the disabled data from 20 samples were analyzed, found that the average satisfaction of users is 4.28, which has a high level of average.
