Abstract
A workpiece aligner, comprising: a base, an actuation assembly for moving a workpiece support, and wherein the actuation assembly comprises first, second and third rotary actuators, each rotary actuator driving a respective cammed rotor which, when rotated, causes the support to move relative to the base, such that the actuation assembly is selectively operative to move the support to cause a translation of the support parallel to a plane, a rotation of the support about an axis orthogonal to that plane, or a combination of said translation and said rotation.
