Using methods of optimal control, parameterized optimal trajectory generation model for wheeled mobile robot in arbitrary performance index was constructed in multi-obstacle environment. By means of numerical method, solving method for model of the nonlinear trajectory generation was introduced in detail. At last, the simulation results verify that model of parameterized trajectory planning for wheeled mobile robot in multi-obstacle and its solving method are valid.
