SENSOR BASED AUTONOMOUS WHEELCHAIR

Abstract

In the fast emerging world, people leading their
life in faster way. But it is highly difficult for the People
With Disabilities (PWD), stroke affected people, paralysis
affected people. They suffer a lot to move from one place
to another and hence the wheelchair was introduced. In
hospital environment the wheelchair based disable people
need a helper. The embedded device acts as a boon for
wheelchair users in hospitals. The places are assigned in
button and based on the people with disabilities
requirement the wheelchair moves to the assigned place
with the help of Brushless DC Motor (BLDC). The PIC
Microcontroller operates the overall design. The Li -
battery package is implemented in wheelchair to give
power. Based on IR sensor the path is identified by the
wheelchair. Also a pulse detection sensor is placed in the
disable body and if they suffer from any health problem an
automatic call to the doctor and nurse takes place. With
the help of GSM modem the operation happens and hence
the doctor can give immediate treatment to the patient.
Also an Electro larynx is placed in the patient's throat,
where the vibration is converted into clear speech. By
connecting the electro larynx with controller, Radio
Frequency (RF) transceiver and speaker the helper at
home satisfies the patient needs.
