1. An apparatus for positioning an object during an assembly operation comprising:

  • a base plate;

    a locator plate for mounting an object;

    a plurality of linear actuators each having a lower end pivotally attached to said base plate in a first predetermined pattern and an upper end pivotally attached to said locator plate in a second predetermined pattern, said lower and upper ends of each said linear actuator being movable relative to one another along a predetermined linear path to move said locator plate relative to said base plate with six degrees of freedom; and

    a control means connected to said linear actuators for selectively actuating said linear actuators to move said locator plate to a predetermined position relative to said base plate for contacting a component to be assembled with an object mounted on said locator plate, said control means being responsive to a force applied to said locator plate during contact between the object and the component for actuating said linear actuators to change the applied force.
