Wall following control of a mobile robot without orientation sensor

The paper presents a novel wall following control of a mobile robot without orientation sensors. The problem is formulated as a path following problem of a mobile robot. The control law derived using the proposed method assure the asymptotic stabilization of the origin by using the Lyapunov method. The effectiveness of the proposed method is shown by experimental results using a P3DX mobile robot utilizing sonar sensors to detect only the distance to the wall without orientation sensor.
