In the Diploma thesis, we discuss the development of a laser profiler for the measurement of the welding gap in automated robotic welding. Presented is the development of a optomechanical system, which first includes the selection and description of the built-in optical components and an embedded computer. This is followed by the spatial placement of the components and designing of holders and fastening elements. Emphasis is on cooling of the system and protection against electrical disturbances. Prepared are two CAD models of the two-piece housing model for the 3D printing variant and CNC milling variant. Both variants are also manufactured. The profiler is assembled and built into the industrial welding robot. In the conclusion of the thesis we tested the performance of the entire system, provided an evaluation of the functioning of the profiler and suggestions for adaptations of the optomechanical system to improve the performance.
