Abstract: A positioning device and method for moving a positioning stage is provided. The device includes a movable stage, at least one actuator, and the same number of sensors as there are actuators. Each actuator is placed such that it applies a force along a line parallel to the line of movement of the positioning stage. Each actuator can be operated to generate an input force for moving the movable stage. A sensor is placed along the force line of each included actuator. Each sensor detects movement of the positioning stage. A first force is applied to a first location on the positioning stage. A second force is applied to a second location on the positioning stage. Application of the first and the second forces moves the positioning stage. The first location and the second location are symmetrically located about an axis of the positioning stage.

Abstract: A positioning device and method for positioning objects is provided. The device includes a movable stage and a pair of levers. The pair of levers is symmetric about a first axis of the movable stage. Additionally, the pair of levers is parallel to a second axis of the movable stage. This second axis is perpendicular to the first axis. Each of the pair of levers applies a force to the movable stage. Each of the pair of levers moves in an arc. The two levers move in opposite directions along their respective arc. The two arcs are symmetrical about an axis of the movable stage.
