Like the Ansco in the previous post this camera also has a wind up motor to advance the film. Designed sometime in the fifties it takes square format images on regular 35mm film similar to the Zeiss Taxona. The Robot is all metal, heavy, and beautifully made. It has interchangeable lenses - mine is the Shneider-Kreuznach Xenar 38mm, f2.8. I also have it's big brother or sister, the Robot Royal but there's been no film through it yet.
