摘要： First of all, in a first step S1, each actuator command value for position command value and posture command value of an end-effector is determined. Next, in a second step S2, rotational resistance values of a first and a second universal joints are obtained, and in a third step S3, the force and the moment exerted to each of the second universal joints are computed using this, and in a fourth step S4, the resultant force and the resultant moment exerted to the end-effector are determined from these. Then, in the fifth step, the elastic deformation amount of a mechanism is computed using these, and a compensation amount of the actuator command value is computed using these values. And then, in the sixth step, the actuator command values determined in the first step are updated with the compensation amount determined in the fifth step taken into account.

摘要： Kinematic parameters of a parallel kinematic machine can be estimated with high precision considering thermal displacement and error of a measuring device, in addition to deformation error caused by self-weight of each component. A DBB device is used when end effectors of a parallel kinematic mechanism machine are positioned at plural positions and in plural postures. In the DBB device, a plurality of support bars are provided with rigid balls on the both ends. One of the balls is fixed on a table and the other ball is provided with an end effector. The position, posture, and distance from a fixed position are measured and based on the measured value kinematic parameters are estimated. In estimating the kinematic parameters, any of deformation error caused by self-weight of each component, thermal displacement of each component, error of a measuring device are added for computation by linear approximation.

摘要： A supporting apparatus for optical unit having an optical unit to expose an original set on a contact glass, a reciprocatingly movable supporting frame body equipped with the optical unit, a sliding member provided on both ends of the supporting frame body, and an eccentric cam mechanism provided on one end of the supporting frame body to vertically adjust one of the sliding member. By operating the eccentric cam mechanism, one end of the supporting frame body can be adjusted to a desired height so as to enable to adjust horizontality of the optical unit mounted on the supporting frame body. Furthermore, because a large gap is provided between a pair of sliding members provided on one end of each supporting frame body and the ends of the two supporting frame bodies where the sliding members are mounted are mutually disposed at reverse side, both supporting frame bodies can be caused to come as close at their home positions as possible.
