First we use motion capture data to set initial state, second use inverse pendulum method to find next position for character`s swing leg in order to maintain balance, third use hermite curve to generate character`s foot trajectory and use inverse kinematics to compute desired angle for swing leg, last we compute desired joint angle for all character`s joint and use PD controller to compute torque for them. In addition to basic walking, this paper presents some methods for character`s balance recover when character get external force, and some details when we simulate biped walking animation. This method can enhance robustness for our system.
