ABSTRACT OF THE DISCLOSURE A simplified object or piece-part positioning system for use with automated product assembly equipment for positioning piece-parts in a predetermined orienta- tion for product assembly purposes. The system includes a support surface coupled to a drive source that is capable of moving the support surface in any direction along a given plane and/or about an axis perpendicular to the given plane in response to drive source positioning signals. The system also includes a part-position sensing module comprising a generally planar array of photosensitive elements electrically divided into a plurality of groups and positioned to sense light from a light source that backlights the piece-part to be posi- tioned located on the movable table, for the purpose of determining any deviation of the photosensitive array sensed shadow of the piece-part from a slightly enlarged piece-part image in order to generate electrical signals representative of such deviation and subsequently employ these signals to cause the drive source to position or overlay the piece-part shadow and indirectly the piece- part within the outline of the enlarged piece-part image in response to piece-part deviation signals generated by the photosensitive element array.
