Abstract:
1. An ultra-precision positioning system, comprising: a base; a motion stage movably provided above a top of the base; a first feeding means including a first actuator and first and second hinge elements with a circular hinge, the first feeding means performing an x-axis translational motion of the motion stage with respect to the base; a second feeding means including a second actuator and first and second hinge elements with a circular hinge, the second feeding means performing a y-axis translational motion and a z-axis rotational motion of the motion stage with respect to the base; a third feeding means including a third actuator and first and second hinge elements with a circular hinge, the third feeding means performing the y-axis translational motion and the z-axis rotational motion of the motion stage with respect to the base in cooperation with the second feeding means; a fourth feeding means including a fourth actuator, first and second hinge members with a circular hinge, a first lever member cooperating with the second hinge member, and a third hinge member cooperating with the first hinge member, the fourth feeding means performing an x-axis rotational motion of the motion stage with respect to the base; and a control means for controlling the first to fourth actuators of the first to fourth feeding means.
