Autonomous stair detection and climbing systems for a tracked robot

Currently autonomous mobile robots offer a diversity of types and functions. This paper mainly emphasizes on a functionality and practicality of self-made tracked robot, which can move autonomously on a bumpy road, such as stairs and slopes. With information on distance obtained by Kinect sensor, the tracked robot is able to identify different types of roads. In addition, we design four modes, including exploration mode, alignment mode, calculating tilt angle mode and climbing mode, to achieve the tasks of identifying and climbing stairs and slopes.
