Abstract:
This project is aimed to provide mobility to such patients which suffers from different physical disabilities such as Amyotrophic Lateral Sclerosis (ALS) in which body is neck down fully paralyzed like in the case of ‘Stephen Hawking’, also for patients with different type of deformities in the body to control the electric wheelchair using mobile phone or hand gesture control in case they are not able to reach the joystick mounted on the wheelchair or command the wheelchair remotely from their beds or easy chairs to provide them complete freedom and independency from any other human/attendee, some sensors are interfaced with the wheelchair to provide safety to the wheelchair user by eliminating the wrong commands which may cause collision with any object/human in the dynamic environment. In recent development wheelchair is equipped with such sensors which not only localize the wheelchair in outdoor environment using GPS but also in indoor environments by using simultaneously localization and mapping algorithms and Laser sensors. Stereo vision camera is mounted at front of wheelchair to provide the depth information which is used to compute the odometry of the wheelchair which is further used by mapping algorithm to map the surrounding environment. Also, the camera feed can be enabled on mobile app to remotely drive the wheelchair from anywhere.
