Authors: Veerubhotla, A; Kumar, S; Bachhal, S; Kumar, A
Abstract: Immobility often causes psychological and
social effects on the person. Since immobility cannot be cured even by using
drugs in most cases, it is essential that such people be given a means of
mobility which does not let their immobility hinder their day to day life. This
paper describes a very feasible mobility solution for the physically impaired
people especially those who are suffering from spinal cord injury in the higher
levels of C1-C7. Independent Electromyogram( EMG) signals obtained from the
neck muscles of the patient using active EMG electrodes have been used to
control the direction of movement of the wheelchair . The direction and degree
of movement of the neck governs the speed and motion of the motor powered
wheelchair. Ultrasonic sensors placed on the wheelchair have been used for
obstacle avoidance. Experimental results have shown that the designed solution
is very feasible, cost effective and requires very less training of the user.
