Abstract
Physically disabled persons find their movements very tough with the existing assistive devices. Though there are many robotics available in recent times to enable their motility they require fine and accurate control which is most of the times not possible in cases of higher disability. These robots are very efficient and enable the user to move around with ease. This paper reports the preliminary work in developing a robotic wheelchair system that involves the movement of the shoulder in directing the wheel chair. The system enables the patient to have command over the robot, its direction of movement and will also sense and alarm the user about the obstacles in the path to avoid collision. This wheelchair helps the patient to move in environments with ramps and doorways of little space. This work is based on previous research in robot path planning and mobile robotics, generally a robot should be interactive, and robotic wheelchairs must be highly interactive to enable the system to work most efficiently.
