V prvem delu magistrske naloge je predstavljena optimizacija obstoječega stroja, ki je namenjen za odlaganje zalitih statorjev na paleto na tekočem traku, po katerem se ti odpeljejo na strojno pregledovanje. Statorji so zloženi na pladnjih, ki jih naložene na vozičke zapeljemo v stroj. Servomotorji zalogovnikov s pomočjo prijemal dvignejo pladenj na prenos, ki ga premika dodaten servomotor. Robot pobira vsak stator posebej, ga odnese na mesto odčitavanja QR kode, nato na preverjanje odtenka njegove barve ter na koncu na paleto, ki se nahaja na tekočem traku. Najprej je predstavljenih nekaj mehanskih predelav, ki so bile potrebne za zanesljivejše delovanje stroja. Opisan je program, ki vključuje: izdelavo programskega bloka za premikanje servomotorjev, izdelavo celotnega avtomatskega cikla zalogovnikov in prenosa, optimizacijo ročnega režima stroja, kodo za izvedbo zajemanja meritev pri analizi merilnega sistema senzorja barve ter optimizacijo zaslonov na kontrolnem panelu. Programiranje je potekalo na Siemensovem krmilniku in panelu s pomočjo njihovega programskega okolja TIA Portal. Stroj zajema meritve barvnih odtenkov statorjev, s pomočjo katerih je izvedeno preverjanje njihove toplotne obdelave. Zato je v drugem delu magistrske naloge predstavljena analiza merilnih sistemov, ki jo moramo izvesti na našem senzorju. Merilni sistemi morajo zagotavljati, da pri opravljanju meritev na pride do prevelikih odstopanj od realne vrednosti. Analiza zato merilnemu sistemu preverja stabilnost, ki predstavlja spreminjanje pristranskosti skozi daljše časovno obdobje, pristranskost, ki predstavlja razliko med referenčno vrednostjo in povprečjem nekega števila meritev, linearnost, ki prikazuje razliko pristranskost skozi celotno merilno območje sistema, ponovljivost, ki nam predstavlja razliko med zaporednimi meritvami enega merilca in obnovljivost, ki nam predstavlja razliko med povprečnimi meritvami posameznih merilcev. Merilni sistem našim zahtevam ustreza takrat, ko so vse naštete lastnosti znotraj mejnih vrednosti. The first part of the master's thesis presents the optimization of the existing machine, which is intended for depositing cast stators on a pallet laying on a conveyor belt, after which they are taken for machine inspection. The stators are stacked on trays, which are loaded onto carts, and then together loaded into machine. The storage servomotors lift the tray to the transmission by means of grippers, which is moved by an additional servomotor. The robot picks up each stator separately, takes it to the location of the QR code reading, then to check the hue of its color, and finally to the palette located on the conveyor belt. First, some mechanical modifications that were necessary for more reliable operation of the machine are presented. The program is described with the following: production of a program block for moving servomotors, production of a fully automatic cycle of storage and transmission, optimization of manual machine mode, code for performing measurement capture in color sensor measurement system analysis and screen control panel optimization. Programming took place on a Siemens system using their TIA Portal programming environment. The machine also includes measurements of the color shades of the stators, with the help of which the verification of their heat treatment is performed. Therefore, in the second part of the master's thesis, the analysis of measuring systems is presented, which we must perform on our sensor. Measuring systems must ensure that excessive deviations from the real value do not occur when performing measurements. The analysis of the measuring system checks the stability, which represents the change of bias over time, bias, which represents the difference between the reference value and the average of some measurements, linearity, which shows the bias difference throughout the measuring range of the system, repeatability, which represents the difference between successive measurements of one appraiser and reproducibility, which represents the difference between the average measurements of individual appraisers. Repeatability and reproducibility can be considered together to obtain a variance equal to the sum of the variations within the measurement system. The measuring system meets our requirements when all the listed properties are within the limit values.

V prvem delu diplomske naloge je opisanih več načinov merilnih metod merjenja notranje luknje rotorskega paketa. Deljene so na brezkontakntne in kontaktne metode. Pri brezkontaktnih metodah je naštetih nekaj glavnih lastnosti merilnika Micro – Epsilon boreCONTROL in MBvision Rotor optical system vision ter njuno delovanje v avtomatiziranem sistemu. Pri kontaktnih metodah merjenja so opisana delovanja merilnikov DIATEST BMD, Mitutoyo SERIES 568 in TESA-Hite 400. Naštete so njihove pomembnejše lastnosti ter njihovo delovanje v avtomatiziranem sistemu, če je ta mogoč. V drugem delu diplomske naloge je podrobno opisano delovanje sistema s presvetlitveno kamero Keyence TM-040 in njen krmilnik TM-3001P. Najprej je predstavljena kamera, katera nam s presvetlitvijo vrne dvodimenzionalno sliko predmeta. Nato so našteti vsi vhodi in izhodi krmilnika ter na kratko opisane njihove namembnosti. Natančno je opisano, kako se nastavi program TM-Navigator in predstavljene so vse meritve, katere lahko uporabljamo. Naštete so osnovne lastnosti krmilnika Siemens 1212C in podano je, na katere načine lahko komunicira s krmilnikom Keyence TM-3001P.

V zadnjih nekaj letih se je pouk v osnovnih in srednjih šolah pri nas in po svetu močno spremenil, k čemur je pripomogel tudi razvoj informacijsko-komunikacijske tehnologije (v nadaljevanju IKT). Dandanes si pouka brez uporabe IKT pri vseh učnih predmetih skoraj ne moremo več predstavljati. V šole so tako prišle elektronske table, interaktivne table, tablice, glasovalne naprave in ostale elektronske naprave, ki lahko ob ustrezni uporabi pripomorejo k večji aktivnosti učencev med poukom in izboljšajo kakovost pouka, saj le-ta postaja vedno bolj dinamičen. Pri tem se uporabljajo različna e-gradiva. Pri razvoju e-gradiv imata v Sloveniji zelo pomembni vlogi Ministrstvo za izobraževanje, znanost in šport ter Zavod Republike Slovenije za šolstvo, ki z medsebojnim sodelovanjem in sofinanciranjem različnih projektov skrbita za razvoj e-gradiv. V okviru diplomskega dela sem izvedel empirično raziskavo, v kateri sem ugotovil, da učitelji poznajo kar nekaj kriterijev za ocenjevanje kakovosti e-gradiv, na katere so pozorni ocenjevalci e-gradiv. Poznajo nekaj javno dostopnih portalov z e-gradivi, ki jih uporabljajo pri pouku računalništva kot dopolnilo za preverjanje učenčevega znanja, kot pripomoček za prikaz delovanja nekega programa in kot pripomoček za učenje katerega izmed programskih jezikov. In the last few years the teaching in primary and secondary schools all around the world changed severely. One of the reasons for the change was the development of the information and communications technology (ICT). Nowadays we can hardly imagine teaching without the use of the ICT. Schools are equipped with electronic boards, interactive boards, tablets, voting systems and other electronic devices. The right use of these devices and electronic materials (e-materials) developed for them can significantly improve the quality of the teaching and contribute to higher activity of pupils during classes, making teaching more dynamic also with using the different e-learning materials in class. In Slovenia both the Ministry of education, science and sport and the Institute of education of the Republic of Slovenia play a very important role as they mutually cooperate and co-finance different projects, which also enable the development of appropriate e-materials. For the purposes of my thesis I conducted an empirical survey in which it was determined that the participating teachers know numerous criteria for quality of e-materials, which the evaluators take into consideration. Teachers are aware of different publicly available e-materials (examples: vidra.si, bober1.acm.si, nauk.si, safe.si, materials COLOS FRI), which they use for teaching computer science. These materials serve them as an additional resource while examining student's knowledge, as a tool to demonstrate the functioning of a certain program, and as a tool to teach a programming language.
