Robot cameras start in 1934 with a 24x24mm negative on 35mm film loaded in a special cassette. This format is found in later cameras even after the Royal Recorder 36 of 1955 used a 24x36mm frame. Robot have also made half frame cameras as well as 12x24 and 6x24 recorder cameras. The Robot SC used a 16x16 frame on standard 35mm film in special cassettes and is perhaps the only model that is a subminiature, at least in have a true subminiature negative size.
The most definitive work on documenting the Robot range of cameras can be found on the German web site http://www.robot-camera.de/ROBOT_Kameras/robot_kameras.html. The technical specifications are easy enough to follow and the photographs graphically show every aspect of the models.
