Mechamasher automation in brewery on Braumat control system
No full textZadatak diplomskog rada je automatizirati stroj za ukomljavanje u pivovari. Potrebno je izraditi
SCADA sučelje na kojemu operater u pogonu radi, osmisliti program koji ispunjava zadaće
naručitelja te uspostaviti komunikaciju između sustava u pivovari na temelju dijagrama cjevovoda
i instrumentacije (P&ID) te funkcionalnog opisa (FDS) rada stroja za ukomljavanje. Koriste se i
MS Excel tablice koje služe za konfiguraciju i parametrizaciju programa, Corel alat za crtanje

create a SCADA interface through which the operator works in the plant, design a program that
performs the tasks of the customers and establishes communication between the systems in the
brewery based on the piping and instrumentation diagram (P& ID) and the functional description
(FDS) of the operation of the Mechamasher. MS Excel tables are used for the configuration and
parameterization of the program, the Corel tool for drawing vector graphics and creating SCADA
and HMI interfaces, the BRAUMAT software that allows the creation of process diagrams, control
of recipes and many other possibilities. After programming in the Simatic Step 7 application, the
written software is tested in BRAUMAT and errors in writing the code are corrected. When the
errors are corrected and the software works correctly, it can be used in a real environment in a

Opening Drawers by a Robot Arm Using Computer Vision and Force Control
No full textU ovom diplomskom radu predstavljena je metoda za otvaranje i zatvaranje ladica robotskom
rukom koja se temelji na raˇcunanju globalne trajektorije pomo´cu raˇcunalnog vida te upravljanju silom i pozicijom tijekom robotske manipulacije. Metode su implementirane i ispitane na
ˇsesto-osnom robotskom manipulatoru UR5 s robotskom hvataljkom Robotiq 3-Finger Gripper.
Za detekciju modela ladice koriste se metode raˇcunalnog vida iz programske biblioteke RVL koje
procesiraju slike dobivene Intel RealSense LiDAR L515 kamerom priˇcvrˇs´cenom pri vrhu alata
robotskog manipulatora. Na temelju modela ladice i medusobnog poloˇzaja dijelova robotskog
manipulatora i ladice, raˇcuna se trajektorija otvaranja i zatvaranja ladice. Upravljanje silom
i pozicijom ostvareno je ˇcitanjem vrijednosti s ugradenog senzora sile i momenta FT 300-S.
Kako bi se osiguralo robusno manipuliranje ladicom, iznos sile se minimizira u lateralnim smjerovima, dok se upravljanje pozicijom odvija u smjeru otvaranja i zatvaranja ladica. Na ovaj
naˇcin, osigurane su adaptivne korekcije lokalne trajektorije otvaranja i zatvaranja. Predloˇzeno
rjeˇsenje sastoji se od tri faze: 1. detekcija modela ladice temeljem snimljene sekvence RGB
i dubinskih slika ljudske demonstracije otvaranja ladice, 2. raˇcunanje poloˇzaja za hvatanje i
hvatanje ruˇcke robotskom hvataljkom te 3. robotska akcija otvaranja i zatvaranja ladice upravljana po sili i poziciji po izraˇcunatoj trajektoriji. Eksperimentalnom evaluacijom utvrdenja
je uspjeˇsnost izvodenja akcije otvaranja i zatvaranja ladice od 62.5%. Ustanovljeno je da detekcija modela ovisi o poloˇzaju kamere u trenutku snimanja slike ladice na kojoj se provodi
detekcija, a najˇceˇs´ce greˇske dogadale su se uslijed krive detekcije modela, odnosno pogreˇske u
dijelu programa temeljenom na raˇcunalnom vidu. Sustav je implementiran i ispitan u Ubuntu
operacijskom sustavu, ROS Noetic distribuciji i unutar Docker kontejnera.This thesis presents a method for opening and closing drawers with a robotic arm based on
the calculation of global trajectory using computer vision and the force and position control
during robot manipulation. The methods were implemented and tested on a 6DoF UR5 robotic
manipulator with a Robotiq 3-finger gripper. Computer vision methods from the RVL program
library are used to detect the drawer model, processing images obtained from an Intel RealSense
LiDAR L515 camera attached to the robot manipulator end effector. Based on the model of
the drawer and the mutual position of the parts of the robot manipulator and the drawer,
the trajectory for opening and closing the drawer is calculated. Force and position control is
performed by reading the values of the built-in force and torque sensor FT 300-S. To ensure
robust manipulation of the drawer, the force is minimized in the lateral directions, while position
control is performed in the direction of opening and closing the drawer. In this way, adaptive
corrections of the local opening and closing trajectory are ensured. The proposed solution
consists of three phases: 1. recognition of the drawer model based on the recorded RGB-D
image sequence of a human demonstration of opening the drawer, 2. calculation of the position
for grasping the handle with a robot gripper, and 3. force and position controlled robot action
of opening and closing the drawer, according to the calculated trajectory. The experimental
evaluation showed that the success of the action of opening and closing the drawer was 62.5%.
It was found that the recognition of the model depends on the position of the camera at the
time of capturing the image of the drawer on which the recognition is performed, and that the
most frequent errors occurred due to incorrect recognition of the model, i.e. due to an error in
the part of the program based on computer vision. The system was implemented and tested in
the Ubuntu operating system, the ROS Noetic distribution and within the Docker container

pospješuje brže razmišljanje i zabavu. Objašnjava kako igrati igru te omogućuje predlaganje novih
riječi koje još nisu u rječniku aplikacije. Također, daje korisniku priliku okušati se u raznim
težinama igre.The aim of this project was to develop a cross-platform application for simulating the popular
game of Kaladont. The application was developed using Android Studio and the Flutter
framework, utilizing the Dart programming language, and Firebase database for suggesting new
words in the game. As a result, the application intelligently and quickly suggests new words,
preventing the input of non-existent or nonsensical words, thus preventing cheating in the game.
It facilitates learning new words, enhances quick thinking, and provides entertainment. It explains
how to play the game and allows users to suggest new words that are not yet in the application's
dictionary. Additionally, it offers the user the opportunity to challenge themselves with various
difficulty levels of the game

Industrial Facility Designing Using Modern Software Tools
No full textCilj ovog diplomskog rada bilo je istraživanje prednosti i mana DDSCAD programa u
odnosu na tradicionalne metode prilikom projektiranja industrijskog postrojenja. Automatiziranim
proračunima struja, napona i opterećenja smanjuje mogućnost ljudske pogreške prilikom
projektiranja i osigurava poštivanje propisa i normi. Obuhvatom svih kategorija električnih
instalacija kao što su sustav za zaštitu od udara munje, elektronička komunikacijska instalacija i
instalacija utičnica i rasvjete nudi cjelokupnu sliku projekta. Unatoč manama prilikom 3D prikaza
električnih instalacija svejedno olakšava projektiranje većih i složenijih građevina dok se
projektiranje manjih građevina, barem za sada, financijski i vremenski ne isplati raditi u DDSCAD
programu.The goal of this master's thesis was to explore the advantages and disadvantages of the
DDSCAD program compared to traditional methods in the design of industrial facilities. By
automating the calculations of currents, voltages, and loads, it reduces the possibility of human
error during the design process and ensures compliance with regulations and standards. By
encompassing all categories of electrical installations, such as lightning protection systems,
electronic communication installations, and socket and lighting installations, it provides a
complete picture of the project. Despite the drawbacks in 3D representation of electrical
installations, it still facilitates the design of larger and more complex structures, while designing
smaller structures, at least for now, is not financially and temporally viable in the DDSCAD
program
