Opis: In today’s technology-driven era, the demand for engineers with strong programming skills continues to rise across diverse industries. LabVIEW software stands out as a key tool in engineering, supporting applications ranging from test and measurement systems to automation and control across different sectors, like manufacturing, aerospace, and automotive. Proficiency in LabVIEW therefore enables engineers to work on a wide range of projects and applications. This article presents two distinct pedagogical approaches to teaching LabVIEW programming at the university level. The introductory course is taught using traditional direct teaching methods, with an emphasis on face-to-face teaching and classroom lectures. In contrast, the advanced course uses a flipped classroom model, where students work independently on preparatory material before participating in laboratory exercises. The latter course concludes with a large project, which the student must complete within four hours. The article provides details on the teaching methods and content of the individual courses, as well as an explanation of the assessment process for the final project. The analysis of the final project results confirms that the students have acquired the knowledge necessary to create functional LabVIEW programs with the appropriate programming style.

Opis: V tem diplomskem delu je predstavljena zasnova programske opreme v okolju LabVIEW za merilno celico 9257A proizvajalca Kistler. Celica omogoča meritve sil v vseh treh oseh koordinatnega sistema (X, Y in Z). Zaradi visoke točnosti je najpogosteje uporabljena za meritve na CNC obdelovalnih strojih. Ker pa obstaja že veliko primerov implementacij v industriji, smo se odločili, da izkoristimo njeno visoko točnost za merjenje odrivne sile pri skoku in športnikom olajšamo analizo ter posledično izboljšamo rezultate.
Ključne besede: merilna celica, Kistler, LabVIEW, meritev, športnik, odriv, maksimalna sila.

Opis: Product assembly is often one of the last steps in the production process. Product assembly is often carried out by workers (assemblers) rather than robots, as it is generally challenging to adapt automation to any product. When assembling complex products, it can take a long time before the assembler masters all the steps and can assemble the product independently. Training time has no added value; therefore, it should be reduced as much as possible. This paper presents a custom-developed system that enables the guided assembly of complex and diverse products using modern technologies. The system is based on pick-to-light (PTL) modules, used primarily in logistics as an additional aid in the order picking process, and Computer Vision technology. The designed system includes a personal computer (PC), several custom-developed PTL modules and a USB camera. The PC with a touchscreen visualizes the assembly process and allows the assembler to interact with the system. The developed PC application guides the operator through the assembly process by showing all the necessary assembly steps and parts. Two-step verification is used to ensure that the correct part is picked out of the bin, first by checking that the correct pushbutton on the PTL module has been pressed and second by using a camera with a Computer Vision algorithm. The paper is supported by a use case demonstrating that the proposed system reduces the assembly time of the used product. The presented solution is scalable and flexible as it can be easily adapted to show the assembly steps of another product.

Opis: Magistrska naloga predstavlja uporabo strojnega vida v avtomatiziranih robotskih procesih. S pomočjo tega imajo roboti možnost vizualnega zaznavanja objektov, simbolov, karakterjev, barv in to delo lahko opravljajo hitro in neizčrpno. Tako lahko roboti samodejno in dinamično manipulirajo z objekti, s katerimi so predhodno manipulirali po točno določenem zaporedju in trajektorijah. Cilj naloge je izdelava preprostega in prilagodljivega sistema 2D stojnega vida, ki robotu s preprosto primi in spusti aplikacijo, pošilja informacije o zaznanem objektu, preko katerih nato robot prosto ležeč objekt v prostoru zgrabi in ga loči v predviden zalogovnik. Pri nalogi sta bila uporabljena kolaborativna robota podjetja Universal robot z oznako UR3 in UR5. Za namen zajema in obdelave slike ter komunikacije z robotskima sistemoma pa je bil uporabljen programski paket LabVIEW z Vision Assistant in Vision Acquisition dodatkom. Uporabljeni sta še industrijski kameri podjetja Basler različnih dimenzij. Od tega je bila večja kamera vpeta fiksno v prostoru, manjša pa na vrhu robotske roke. Za primerjavo se je uporabila tudi enostavna USB endoskopska kamera, ki je bila zaradi majhnih dimenzij prav tako pritrjena na vrhu robotske roke. V tem se boste seznanili z navodili za izdelavo robotske aplikacije s strojnim vidom v programskem paketu LabVIEW.
