Abstract: A mechanism for determining the position of a point relative to a coordinate system defined by coordinate scales aligned along coordinate axes includes a coordinate reference plane and a coordinate read plane and a read mechanism associated with each coordinate scale. Each read mechanism is engaged with the coordinate read plane and the coordinate reference plane to be responsive to relative motion between the coordinate read plane and the coordinate reference plane to indicate a position of the point on the along the corresponding coordinate scale, and is coupled to the coordinate read plane and to the coordinate reference plane to allow relative transverse motion between the coordinate read plane and the corresponding coordinate axis. Each read mechanism includes a guide mechanism for retaining the read mechanism at a predetermined position along an axis transverse to the corresponding coordinate axis with transverse motion between the coordinate read plane and the coordinate reference plane.

Abstract: A microgripper for gripping and releasing an object, particularly very small objects. The microgripper includes a support and two cantilevered flexible arms, each of which is mounted on one end to the support. The other ends of the flexible arms are capable of being flexed toward and away from each other. A servomotor, is affixed to the support. There is a slide arrangement driven by the servomotor and which is adapted to move the unmounted ends of the flexible arms toward or away from each other, thereby providing, respectively, a gripping or releasing movement. An apparatus which includes a micromanipulator, the microgripper which is operationally, detachably affixed to the micromanipulator, and a control system which is electrically connected to the motor means whereby the movement of the slide arrangement is controlled.
