Design and Development of Stair Climbing Robotic Wheelchair

Abstract

This paper presents the design and implementation of a robotic wheelchair capable of navigating both flat surfaces and staircases. The robot uses a single front- mounted Infrared sensor for detection and navigation. It allows for manual control and can switch to automated stair-climbing mode with a user controlled button. The algorithm positions the robot at the base of the stairs, raises its front section when the sensor no longer detects an obstacle, and then advances a set distance while continuously monitoring for additional steps. This design emphasizes simplicity and efficiency, offering a practical solution for stair navigation with minimal hardware. This chair increases the lifeline of special ability person who don’t climb the stair. In social area special ability person easily access their daily routine by our stair climbing chair.
