This paper investigates the exponential stabilization problem for a kind of nonholonomic robots with uncalibrated visual parameters based on the uncertain nonholonomic chained model. Two kinds of controllers are designed for exponential stabilization of the nonholonimic system by using the auxiliary variable method and the input control method. This two kinds of controllers not only overcome the limit of the initial status of the system but also have high unification. Simulation results show the effectiveness of the proposed methods.
