The presented system is designed as a robust and cheap solution, using only the equipment needed for the production tasks in the robot cell. The main goal of the presented system is to use vision measurement system for measuring and calibration procedures and laser welding equipment to weld two protector assembly parts together where positioning tolerances are very narrow. These narrow tolerances forced us to implement auto-checking and auto-calibration procedures for all necessary mathematical aspects in the robot cell, based on the robust visual touch-up method. To demonstrate adequate solution in the measurement, calibration and also the production sequences, the graphs show production statistical results over a one year production period"},{"@xml:lang":"sl","#text":"Namen članka je opis uporabe poenostavljene video-dotične metode za namene kalibracije oziroma definiranja metematičnih transformacij uporabljenih v industrijski robotski celici za varjenje in merjenje dimenzij izdelka imenovanega protektor. Naloga, ki smo jo morali rešiti pri tem industrijskem projektu je zajemala merjenje dveh dimenzij v protektorju in definiranje točke varjenja dveh sestavnih delov protektorja, vijaka in bimetala. Predstavljen sistem je zasnovan robustno in s cenovno sprejemljivo opremo, minimizirana le na nujno potrebno, kajti omejitev delovnega prostora je bila zelo velika. Naloga je bila izpeljana z uporabo poenostavljene video-dotične metode in enostavne, vendar zelo efektivne kalibracijske metode, ki zagotavlja delovanje sistema znotraj predpisanih merilnih in varilnih toleranc. Pristop je omogočil izvajanje meritev in določanje točke laserskega varjenja z mejo pogreška +/-0,1 mm"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:doc-VYXNXA9X","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-VYXNXA9X"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-VYXNXA9X/be99f777-e5e9-41d2-b4b3-c7dcd1bf3c46/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza v Ljubljani, Fakulteta za strojništvo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:doc-VYXNXA9X/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-VYXNXA9X"}}}}
