Abstract
An apparatus is provided for determining the angular deviation of a randomly angular oriented article from a desired angular orientation in preparation for its engagement by a robotic part handling device. The apparatus projects a rotating image of the article onto a mask which is representative of the article in a desired orientation and provides an angular deviation signal indicative of the cummulative angular displacement of the image from an initial reference position at which the image matches the mask.
