Abstract
There are provided kinematic arithmetic method and apparatus for evaluating positions and orientations of links of a link mechanism in which a plurality of links are coupled through joints. An angular acceleration of a joint is evaluated by substituating on a numerical basis an angle, an angular velocity, and a torque, of the joint into a relation. A numerical integration of the angular acceleration of the joint thus determined is preformed to evaluate the angle of the joint. A kinematics operation is performed to evaluate positions and orientations of the links on the basis of the angle of the joint determined through the numerical integration. A resultant of the kinematics operation is displayed.
