A bending angle of each joint (3, 4, 5) of a multiple-jointed object (1) is represented with a function (functions (1) to (4)) independent of a length between joints of the object. Based on the function, contour data is produced for a motion of each joint, which is then displayed on a screen (17). This unnecessitates the operation which has been conventionally achieved to generate functions each time the object is changed in its size. Namely, the functions are independent of the size of the object. Since parameters (Dm, Amn, psi mn, m, n, phi m) of the functions are altered to additionally assign characteristics to changes in the bending angles of the respective joints, the object can be actuated in an action having an emotional expression. <IMAGE> |
