This paper discussed an automatic measurement system used for checking the accuracy of tunnel profile. Such checks, in all work phases from construction to maintenance after completion, requires measurements as well as analysis and assessment of data obtained. This sophisticated system has been developed through high-level automatization of all these tasks (partially robotized). The system has two functions which support the measurement, i) positioning and ii) detection. The capability i) teaches the installation position of the measurement device. This position in a coordinate system is detected by the function ii). These function detailed here are elements essential for future construction robots.
