Autonomous staircase climbing robot for rescue application

摘要

Abstract This paper discusses the construction and application of an autonomous staircase climbing robot. Such a robot has several applications in real life. It can be used in dangerous regions for surveillance, rescue, and exploration with the help of a camera placed on it or by carrying resources. After going through various research papers a concept of such a robot was visioned. Following which design was formulated and simulations were carried out. A prototype was fabricated with mechanical and electrical parts. It is a simple climbing robot with two rods as support at the front. A simple rack and pinion gear are used to lift the robot while climbing. An ultrasonic sensor is placed at the front to sense the width and height of the stairs. Various testing and analysis have been done on the prototype to eliminate all drawbacks. The robot has shown to successfully climb the stairs.
