The '''Robot II''' was a mechanical [[135 film]] camera by [[Robot (camera)|Robot]]  introduced in 1938.
It was a slightly larger camera than the [[Robot I]], with some significant improvements but still using the basic mechanism. Among the standard objectives were 3&nbsp;cm Zeiss Tessar and a 3{{frac|3|4}}&nbsp;cm Zeiss Tessar in 1:2,8 and 1:3,5 variations, a 1:2,0/40&nbsp;mm Zeiss Biotar and 1:4/7,5&nbsp;cm Zeiss Sonnar.

The film cassette system was redesigned but it was only with the '''Robot IIa''' launched in 1951 that film could accept a standard 35&nbsp;mm cassette. The special Robot cassettes type-N continued their role for take up. A small [[bakelite]] box was sold to allow people to rewind colour film into the original cassettes as demanded by the film processing companies. The camera was synchronized for flash. The swinging [[viewfinder]] was retained but now operated by a lever rather than moving the entire housing. Both the deep purple filter and the yellow filter were eliminated in the redesign. Some versions were available with a double wind motor which could expose 50 frames. The [[Second World War]] stopped civilian production of the Robot but it was used as a [[gun camera]] by the [[Luftwaffe]].

The Robot II took square photographs in the 24×24mm format, which allowed 50 exposures to fit on a 36-exposure film. It featured an all-metal Rotor shutter (1/4 to 1/500), a direct vision finder, and a screw mount for interchangeable lenses by [[Schneider Kreuznach|Schneider]]. The standard lens is a Schneider Xenon 40&nbsp;mm f1.9.

Also available was the '''Robot Star II/50''', with a double spring motor for 50 exposures and a Xenar 38&nbsp;mm f2.8 lens.
