Abstract: Methods for moving and controlling the position of an article are described. In one embodiment, the method employs a conveyor including a substantially planar surface and a support member situated opposite the substantially planar surface. An article is placed between and in contact with both the substantially planar surface and the support member. And at least one of the conveyor and the support member are moved wherein the article is both rotated and translated so that the rotation amount substantially matches the translation amount.
