The stabilizing problem of stochastic nonholonomic mobile robotswith uncertain parameters is addressed in this paper. Thenonholonomic mobile robots with kinematic unknown parameters areextended to the stochastic case. Based on backstepping technique,adaptive state-feedback stabilizing controllers are designed for nonholonomic mobile robots with kinematic unknown parameters whose linear velocity and angular velocity are subject to some stochastic disturbances simultaneously. A switching control strategy for the original system ispresented. The proposed controllers that guarantee the states ofclosed-loop system are asymptotically stabilized at the zeroequilibrium point in probability
