V magistrskem delu je predstavljen razvoj robotske celice za kovanje vil, ki bo nadgradila obstoječi obdelovalni proces tako, da bo omogočal popolno avtomatizacijo kovanja vil. V prvem koraku smo predstavili obravnavani tehnološki proces kovanja vil. Proces smo v nadaljevanju razdelili na posamezne tehnološke operacije. Podrobno smo analizirali zahteve, ki nam jih je podal naročnik in smo na podlagi tega izvedli razvojni cikel snovanja robotske celice. Pri snovanju smo izdelali detajlne modele novih naprav, prijemala in celotne robotske celice. Za posamezne naprave smo izvedli analitično analizo njihovih sestavnih elementov in komponent. V nadaljevanju smo izdelali program gibanja robotske roke in izdelali simulacijo premikanja roke v prostoru. Na podlagi simulacije gibanja robotske roke smo določili delovni cikel posameznih operacij in celotni cikel kovanja vil. V zadnjem delu magistrske naloge pa smo izračunali predvideni obseg izdelanih kosov na novem obdelovalnem procesu kovanja vil in ga primerjali z obstoječim procesom ter tako izračunali procentualno povečanje obsega proizvodnje. The master's thesis presents the development of a robotic cell for forging forks, which will upgrade the existing machining process in order to enable the complete automation of forging forks. In the first step, we presented the considered technological process of forging forks. The process was further divided into individual technological operations. We analysed in detail the requirements given to us by the client, furthermore, based on this we carried out the development cycle of a robot cell design. During the design, we made detailed models of new devices, grippers and entire robotic cells. Also, analytical analysis of their constituent elements and components was performed for individual devices. Moreover, we have also created a program for the movement of the robotic arm and made a simulation of the movement of the arm in space. Based on the simulation of the movement of the robotic arm, we determined the working cycle of individual operations and the entire forging cycle of the forks. In the last part of the master's thesis, we calculated the estimated volume of manufactured pieces on the new machining process of forging forks and compared it with the existing process, thus calculating the percentage increase in the volume of production.

V diplomskem delu je predstavljen obstoječ postopek barvanja obdelovancev, katerega hrbtenico predstavlja viseč verižni transporter. V nadaljevanju so prikazani razlogi in zahteve glede razširitve sistema. Prikazano je snovanje razširjenega verižnega transporterja, izračun njegove nosilne konstrukcije ter njegovih pogonskih komponent. Tako je s programom SolidWorks izdelan prostorski model nosilne konstrukcije transporterja, ki je v nadaljevanju analizirana s programom Abaqus po metodi MKE. Za viseči verižni transporter smo določili silo v verigi, potrebno vlečno silo ter preverili, če obstoječi elektromotor ustreza novim obratovalnim zahtevam. In this bachelor thesis, the existing procedure for workpieces colouring based on overhead chain conveyor is described. The reasons and requirements for upgrading of the system are presented. Extension of overhead chain conveyor and calculation of its supporting structure and its drive components are preformed. Thus, a spatial model of conveyor supporting structure is designed using Solidworks software and further analysis with Abaqus software according to FEM method is conducted. Furthermore, the chain force and subsequent required pull force is determined and evaluation weather the existing electric motor meets the standards of the new operating requirements is made.

Diplomsko delo obravnava področje brezpilotnih letečih naprav, njihovo varno uporabo ter potrebne komponente za njihovo brezhibno delovanje. V uvodu diplomskega dela so opisane brezpilotne naprave, ki se uporabljajo v hobi, polprofesionalne ter profesionalne namene, predvsem za potrebe video-snemanja iz zraka. Tu imajo prednost novejše naprave, pogosto imenovane tudi droni, predvsem v obliki multikopterjev. Sledeč uvodu je opis komponent, ki sestavljajo brezpilotne naprave od nosilnih konstrukcij, pogonskih sklopov do snemalne tehnike, ki se pogosto uporablja v te namene. Opisana je funkcionalnost teh komponent in naloge, za katere se uporabljajo. V četrtem poglavju je opis izgradnje redundančnega napajalnega vezja za potrebe brezpilotnih naprav. Vezje je zamišljeno kot manjše, robustno in zgrajeno iz osnovnih elektronskih komponent. Omogoča napajanje video oddajnika, RC sprejemnika in krmilne elektronike brezpilotne naprave ter krmilnih servomotorjev (v primeru letal). Napajanje vezja je preko 3 baterij LiPo (2 x 7.4 V in 1x 14.8 V). Predvideni izhodi napajalnega vezja so 5 V 3 A za RC sprejemnik, 5 V 20 A za servomotorje in 11 V 3 A za video oddajnik. Oba 5 V izhoda imata redundančno napajanje preko 2 baterij, za neprekinjeno delovanje v primeru izpada ene od njih. Sledeč razlagi posameznih sestavih pod-enot napajalnega vezja so tudi meritve, ki so bile opravljene. Te kažejo skladnost s prvotnimi zahtevami ter kažejo druge parametre. V zaključku so splošne ugotovitve glede varnostnih zahtev brezpilotnih naprav, analiza rezultatov izdelanega vezja za napajanje brezpilotnih naprav ter splošne ugotovitve in predlogi na nadaljnje delo. The following thesis discusses the field of unmanned aerial vehicles (UAVs), their safe use and the components which comprise them to assure their flawless operation. The introduction of the thesis describes the various UAVs used for hobby, semi-professional and professional use. The UAVs discussed are mostly used for aerial video-photography. Priority is on newer UAVs, also popularly described as drones, in the form of multicopters. Following the introduction there is a description of components commonly used to construct this type of UAVs. The components described range from frame and propulsion components to video equipment that is commonly used. Described is the use of these components along with their features and limitations. The fourth chapter describes the design and construction of a redundant power supply to be used in the forehand mentioned UAVs. The power supply is designed to be small, robust and created from basic and common electronic components. The power supply is able to power video equipment, an RC receiver and UAV control electronics and servomotors used in the UAV (this is mostly applicable to airplane UAVs). The power supply circuit is powered from 3 LiPo batteries (2 x 7.4 V and 1 x 14.8 V). Outputs of the power supply are 5 V 3 A for the RC receiver, 5 V 20 A for the servomotors and 11 V 3 A for video equipment. Both 5 V outputs are redundantly powered by 2 LiPo batteries. In case that one fails the other takes over and the circuit continues providing power. After the description of each of the circuit blocks, the measurements results obtained on each output are presented. Measurements show the conformity of the power supply circuits to the demands they have to be met along with other noteworthy parameters. The conclusion of the thesis gives general findings about UAV safety, discusses the power supply circuit made and gives other findings and suggestions for further work.
