In this project we are aimed at making an automatic stair climbing wheelchair with bed. A concept for a stair climbing wheelchair capable of moving in structured and unstructured environments, climbing over obstacles and going up and down stairs and also converted into bed. The mechanisms involved in this system are rack and pinion mechanism and the worm and gear mechanism. All these mechanisms are operated by using the dc motors, controlled by the wireless remote controller and the micro controller.In this design of the wheelchair consisting of a frame and a seat. When the wheelchair faces an obstacle such as a step or a stair, it can be operated to overcome that.
