Abstract
The degradation of mobility is an important concern that affects the independent living ability of physically Challenged people. Therefore, mobility assistive devices require improvements to uplift the living standards of the people. This paper sets out a design of a smart wheelchair using an embedded system. This paper sets out a design and development of a smart wheelchair using an embedded system. The proposed design of the wheelchair can be controlled through bluetooth which enables the user to control the wheelchair with less effort. Touch commands are deployed to the system in addition to the virtual joystick-controlling interface to enhance the interaction with the user. This aids the disabled in carrying out daily activities independently within indoor environments. Experiments are conducted to verify the functionality of the developed smart wheelchair.
Highlights
This paper focuses on the problems faced by speciallyabled people who wish to commute on their own, but they cannot drive because of natural causes
The Raspberry PI 3 program checks the code received by the Bluetooth module and if it is a matching character with a given program, with each respective character the Raspberry PI 3 sends a signal to the motor driver
We developed a wheelchair that includes ultrasonic sensors to smart track the paths and can detect the objects in the middle of the path along with an ability of maintaining good care to refrain from tragedy, good results are obtained
Summary
This paper focuses on the problems faced by speciallyabled people who wish to commute on their own, but they cannot drive because of natural causes In this proposed project, the emphasis is on Bluetooth control of the wheelchair with automatic movement in the directions like forward, backward, left, right and diagonal directions through Bluetooth command. If a person who’s minor part of the body is working he or she can use it with the least efforts and maximum precision and speed control This device is loaded with many additional features which make it smart. This wheelchair is developed to overcome the above problems allowing the end-user to just perform safe movements and accomplish some daily life important tasks. Taking all this in consideration we have decided to work on a bluetooth operated wheelchair
