The Robot Junior is a scaled-down, budget version of the Robot Star camera. It was produced by the Berning Robot Co. in Germany starting in 1954.
Like almost all Robot cameras, the Robot Junior is a spring-wound, mechanical clockwork camera. The knob on the top of the camera is wound up, tension-ing a main spring which then drives the shutter and film advance. The Robot Junior makes square 24x24mm exposures on 35mm film. Like the Robot II and Star, the Junior can use standard 135 film cassettes on the loading side, but still makes use of a proprietary Robot cartridge for film take up. This cartridge is necessary for the Junior as it does not have a rewind knob.
The camera has interchangeable lenses, using a screw-mount 26mm style found on several other Robot cameras. The shutter is a rotary design and is capable of speeds up to 1/500th. The standard lens is a 38mm f/3.5 but - as noted - one may mount a variety of lenses onto this camera.

Robot Junior
How do you beat the heat of summer and which cameras do you do it with? One of our staff opted for the underground approach, spelunking his way through a nearby lava tube. He took this Robot Junior along with him. You don't often expect to run into Robots in the deep, dark, depths of a cave, but there are exceptions to every rule.
