IoT based automated Wheel Chair for Physically Challenged

Abstract

The purpose of an automatic wheelchair (AWC) is to assist and support paraplegics. The proposed chair is particularly suited for people with a higher level of impairment, such as quadriplegics who are unable to move any of their body parts except their head due to their advanced age or infirmity. We created a microcontroller-based wheelchair that moves with the patient's head motion. Electronic and mechanical components make up the system. An accelerometer monitors the patient's head nodes in all four dimensions for head motion recognition. The paper goes over the Bluetooth technology on the wheelchair, as well as the accelerometer that powers the motors and controls the chair's motions inside the house. Our wheelchair is designed with the patient's health in mind as well as the device's maneuverability. The pulse rate and blood oxygen levels are monitored by sensors using an Internet of Things approach. The ultrasonic sensors aid with obstacle recognition, making it easier to move the chair in a certain direction. By observing the directions of head movement along the x and y axes, the implanted accelerometer aids the chair in determining which movement the patient wishes to make. The signal is then sent to the microcontroller. The wheelchair is controlled by a microprocessor-based on the direction of acceleration, and it moves in LEFT, RIGHT, FORWARD, and BACKWARD with the help of viper motors.
