Motorized Wheelchair with Bluetooth Control and Automatic Obstacle Avoidance

Abstract

The new innovation in technology has led to a lot of improvement in an electric wheelchair assisted by Glove. The work presented here is a model of a motorized wheelchair system that is controlled wirelessly using a glove. Alongside manual control, the wheelchair system is also enabled with automatic obstacle avoidance. Bluetooth Low Energy protocol is used for wireless control. Dual ultrasonic sensors on either side of the caster wheels on the wheelchair are used for obstacle avoidance. The glove, which is the main method of control will have a simple switch design implemented with the help of conductive ink as a means to control the direction of the movement of the wheelchair. The microcontroller onboard the wheelchair will process the input received wirelessly from the glove and data from the ultrasonic sensors to determine the direction the wheelchair should move in. The goal of this wheelchair system is to try and provide the best possible control method for motorized wheelchairs to simplify the lives of people who are dependent on such wheelchairs due to disabilities or accidents.

Design of personal mobility system for assisted agricultural work with self-adjusting center of gravity

“…The manual manipulation of an intelligent controller can drive a personal mobility system to complete a variety of functions such as moving forward and backward, steering, standing, and lying down. Such high-tech products involve modern precision machinery, intelligent numerical control, engineering mechanics, and other fields [6][7][8][9][10][11].…”
