Joy stick operation speed of intelligent robotic wheelchair

People bound to wheelchairs require assistance maneuvering over steps encountered when moving about roadways and walkways. We propose an intelligent robotic wheelchair which enables a wheelchair bound person to climb steps without third-party assistance. By using this proposed mechanism, a user may maintain inverse pendulum control while raising the front wheels of the wheelchair, then moving forward to the step maintaining the inverse pendulum control, and finally, climbing over the step using a DC motor force from the rear wheel shafts. We propose a joystick controller in this document to investigate improved wheelchair maneuverability and facilitated human interface. This paper presents the experimental results of the joystick operation speed dependant on LED panel instructions.
