The Berning Robot Royal 36s is a 35mm viewfinder camera produced by the German maker Otto Berning & Co., part of the Robot series known for spring-motor film advance. It uses standard 35mm film and was positioned as a precision rangefinder-style instrument rather than a mass-market consumer camera.

Auction data for the Robot Royal 36s is thin: a single recent UK saleroom result hammered at £190 in January 2025, which gives only a rough indication of value in today's market. Because hammer prices reflect wholesale auction levels rather than dealer retail, a clean working example offered through a specialist shop typically sells for more, and condition, completeness and mechanical function strongly influence what one is worth.
