This paper deals with an automatic technical system for determining the optimal parameters of the visual inspection of the sheet metal. Since quality control is necessary to find errors at an early stage of production and to reduce future losses, it is necessary to find the optimal recording parameters to make the errors as noticeable as possible. The required errors are surface damage in the form of dots or lines, and sheet metal recesses. Since all the faults are not equally visible at all light angles and camera, their optimal range is required. Finding this range in manual mode is a hard-labouring job due to the fact that it is it is necessary to ensure the parallelism of the camera, the light, and the file with the angle change, therefore it is necessary to automate this process. The aim of this work was to create a technical system that would integrate two robots, a carrying strap, a computer, a camera and an encoder. Automation of the process involves automatical modification of various technical parameters, recording and evaluation. Two modes of operation were created, the first to automatically search the area where the errors are most visible and the other one that serves the most accurate parameter setting. In the first part of the final paper are presented the elements of this technical system and its scheme. The second part refers to communication between individual elements and some problem solutions. The final part will show the robot programs and the results of the recordings.
