The Robot was deigned by Heinz Kilfitt and produced by a division of Berning. The camera appeared in 1934, later designated the model I it was replaced in 1939 by the model II. The model I is recognisable by the separately mounted view-finder which swivels for viewing at right-angles, on the model II the finder is integral to the top housing. There are several differences in the model I, on the earliest the motor winding knob has a domed top and the camera back is secured by a screw.

To reduce friction and ease film movement the pressure plate is pushed back clear of the film as the film is advanced. The film is moved from cassette to cassette, these open when the camera back is closed. The cassettes used in the Robot I are different to later models.

The shutter is simple but quite ingenious. The basis is a rotating disc with a fixed sector cut-out for making the exposure. A coiled spring stretches from the speed setting dial to the shutter disc, turning the speed dial alters the tension in the spring and so adjusts the speed. For slow speeds the disc is halted during the exposure. Around the speed dial is a cam, one end of an angled lever rests against the cam the other end of the lever has an escape wheel and pallet (delay mechanism). Attached to this end of the lever is a fork able to intercept a pin on the rotating disc. The cam moves the lever towards or away from the edge of the disc and hence the pin, in this way the fork engages the pin to a different depth and so remains stationary for a different time. For higher speeds the lever is moved completely clear of the disc by the cam. When the yellow/green filter is deployed the shutter speed is reduced to compensate.

The Minitography & Cinetography catalogue for 1938 lists the model I with an f2.8 lens at £24.10.0 and the telephoto lens at £10, other accessories listed are a lens hood, filters and close-up lenses.

The model II appeared in 1939. This example is a later post-war model. The lens is fixed focus.

The spring powered motor can expose 12 frames in one winding, a double spring version was also available for the Model II. Accessories were available for remote release and unattended operation.
