Apparatus and a method for balancing and damping control in whole body coordination framework for a biped humanoid robot. The method comprises the steps of: (a) damping the structural vibration of the main body of the robot caused when the robot walks; (b) compensating for the trajectories of the zero moment position (ZMP) and the center of mass (COM) of the robot which changes in accordance with the damping of the structural vibration; and (c) compensating for the body orientation of the robot which changes in accordance with the damping of the structural vibration and the trajectory of the COM.
