ABSTRACT:
Technology is provided that can compute a center of gravity pathway for a robot in which the ZMP matches the target ZMP, even if the robot is caused to perform a crouching movement during a single leg ground phase. The robot of the present invention is a legged robot that moves the center of gravity in the vertical direction when one leg link is grounded by changing joint angles, and comprises means for generating the vertical pathway of the center of gravity, means for computing the horizontal pathway of the center of gravity, based upon the generated vertical pathway of the center of gravity, a tridiagonal equation which is a discretization of a ZMP equation, a target ZMP, and horizontal speeds of the center of gravity at the beginning and the completion of the vertical pathway, means for computing chronological data of target values of the joint angles, based upon the generated vertical pathway and the computed horizontal pathway of the center of gravity, and means for rotating the joints based upon the computed chronological data of the target values of the joint angles.
