Wah Tint · 2021
The paper presents the implementation of Arduino-controlled Smart Wheelchair design based on theoretical and experimental approaches.Different types of smart wheelchairs have been developed in the last few years.Inventors and researchers have been an effort to upgrade the standard of human life.Now, new generations of wheelchairs are being developed.This paper describes the implementation of an android controlled smart wheelchair using the user's command.The wheelchair can be operated with five functions which are driving forward, turning left and right, including moving backward and stop, and at the command of the user on an android phone and tablet.This research is connected with a Bluetooth module as a UART port to automatically drive the system.This proposed system is based on Raspberry Pi 3 and a high current motor driver with the gearbox.The proposed system in this paper is intended to help persons who disabilities in the lower body and old age people by implementing a touchscreen-based system for a smart wheelchair.The temperature sensor and heartbeat sensor are used for the patient's health care in this system.The battery is used as the power supply for this system.This system is designed to reduce the user's human effort and force to drive the wheel for the wheelchair.The experimental results had been confirmed the system robustness with theoretical studies in control system design and applications.
