Parallel Evolutionary Algorithm EDA Based on Copulas
Hyrš, Martin ; Brandejský, Tomáš (referee) ; Matoušek, Radomil (referee) ; Schwarz, Josef (advisor)
In my thesis I~ deal with the design, implementation and testing of the advanced parallel Estimation of Distribution Algorithm (EDA) utilizing copula theory to create a~ probabilistic model. A~new population is created by the process of sampling the joint distribution function, which models the current distribution of the subpopulation of promising individuals . The usage of copulas increases the efficiency of the learning process and sampling the probabilistic model. It can be separated into mutually independent marginal distributions and the copula , which represents the correlations between the variables of the solved problem. This concept initiated the usage of the parallel island architecture , in which the migration of probabilistic models belonging to individual islands ' subpopulations was used instead of the migration of individuals . The statistical tests used in the comparison of the proposed algorithm ( mCEDA = migrating Copula - based Estimation of Distribution Algorithm ) and the algorithms of other authors confirmed the effectiveness of the proposed concept .
Optimization of EDM process control parameters
Prokeš, Tomáš ; Beneš, Libor (referee) ; Bednář, Josef (referee) ; Matoušek, Radomil (advisor)
The dissertation thesis is focused on the optimization of control parameters of an EDM machine; the subject of optimization is cutting speed and surface topography. The first part of the thesis contains a research study on the technology of electrical discharge machining with the attention paid to the optimization methods use for control parameters of this process. The second part of the thesis is focused on real application of knowledge gained from studied sources. Here, a design of experiment aim at optimizing the parameters of the EDM machine is designed and carried on to maximize the cutting speed with the highest possible surface quallity. The result of the work is to build adequate regression models and find the optimal setting of machine control parameters.
GREENHOUSE DESIGN USING SIEMENS LOGO!
Vymětalíková, Lucie ; Lang, Stanislav (referee) ; Matoušek, Radomil (advisor)
The aim of this bachelor thesis was to design and implement an automated greenhouse. The system is controlled by a simple programmable controller called Siemens LOGO! The regulated quantities are air temperature, humidity, soil moisture and light intensity. For the possibility of the greenhouse remote checking, a website was designed.
VISUAL INSPECTION OF WELDING OF PLASTIC SQUEEZE TUBES
Furik, Pavel ; Holoubek, Tomáš (referee) ; Matoušek, Radomil (advisor)
Bachelor’s thesis deals with machine vision systems in order to inspect plastic squeeze tube seals. Principle and options for choice of vision systems are summarized in theoretical part of the thesis. Based on this summary, a selection of vision system and inspection application design was to be created that would inspect selected parameters of plastic tube seals. This design was to be tested and evaluated by behavior of system with varying contrast.
FLUID HANDLING USING THE ABB YUMI PLATFORM – PIPETTING
Smolinský, Michal ; Parák, Roman (referee) ; Matoušek, Radomil (advisor)
The aim of this bachelor thesis is to create a control program for the collaborative robot IRB 14000, whose task is the accurate dosing of liquid using a pipette. The introduction introduces the collaborative robotics industry, followed by a description, development and ABB products. After the introduction of the model of the used robot, attention is paid to the issue of liquid handling, which includes the selection of a suitable pipette. The application performed by the robot and its creation forms the rest of the work, which includes, in addition to the original pipetting task, an extension in the form of a separate task. The aim of this task was to prepare a mixed drink for the purpose of presenting the used robot. The following last part describes the process of testing both tasks on a real prototype robot, the product of which is a video, which is part of the appendix.
FLUID HANDLING USING THE ABB YUMI PLATFORM
Červenka, Roman ; Parák, Roman (referee) ; Matoušek, Radomil (advisor)
The goal of this bachelor thesis is to design and create program for laboratory manipulation. The robot will handle beakers. For further presentation of possible usage of ABB YuMi, a program for drink preparation was made. For robot programming, RobotStudio was used, in which was used RAPID programming language. To understand the philosophy of using RobotStudio to program robots, was also one of the goals of this work. At the end the created programs were tested in robotics laboratory and the results of this work were evaluated.
Ninepin Bowling Automata – elevator and ball thrower
Robota, Jakub ; Holoubek, Tomáš (referee) ; Matoušek, Radomil (advisor)
The goal of this master’s thesis was to design and construct ninepin ball elevator for automated pin setter machine and ninepin ball launcher to simulate load and to verify correct function of the setter machine. Also, a ball track was designed as a means of transport for the ball from elevator to launcher. Theoretical part of thesis contains research into ninepin bowling, its rules and analysis of different applicable solutions found on the market that deal with automated pin setters and their ball elevators. Furthermore, a separate research into ball launchers was conducted. Practical part of thesis was comprised of own solution to design and construction of elevator, which extended already designed pin setter machine. After this, track for ball was designed and constructed together with ball launcher which imitates load that would the machine experience during usual game.

Nevoral, Tomáš ; Holoubek, Tomáš (referee) ; Matoušek, Radomil (advisor)
This thesis deals with the design of an automatic non-string pinsetter machine for nine-pin bowling. Firstly, a summary of rules and technical standards important for constructing an automatic pinsetter machine was created. The next part of the thesis contains market research and verification of patent safety. The final part of this thesis is focused on the conceptual design and construction of an automated pinsetter machine. Complete construction and technological design of the sweep wagon, horizontal and vertical elevator of skittles and their practical implementation. Design of (AC) drives for the motorized assembled parts.
DESIGN OF AUTOMATIC PIPETTING HEAD ON THE PRINCIPLE OF PERISTALTIC PUMP
Čížek, Petr ; Lang, Stanislav (referee) ; Matoušek, Radomil (advisor)
The aim of this diploma thesis is to design and create a prototype of automatic pipetting head that will be useful for pipetting in laboratories after attaching it to a robotic manipulator. In the beginning, a research about various types of automatic pipetting heads was made followed by a device design and component analysis. The prototype was made using 3D printing method and it utilises a peristaltic pump, Arduino microcontroller and Bluetooth interface. A measurement of repeatability and dispensing accuracy was made on the finished device. The results are evaluated in the conclusion.
Visual inspection of component dimensions
Kadaňka, Jan ; Holoubek, Tomáš (referee) ; Matoušek, Radomil (advisor)
This master thesis deals with the comparison of an industrial system for object recognition and measurement with an affordable camera on the Raspberry Pie platform. The theoretical part briefly describes several methods for measuring dimensions, which are commonly used in industry, along with a general description of technical equipment for image recording. The next section describes 3 industrial systems for image analysis. The practical part of the work deals with the design of the measuring stand, the description of the technical equipment, the implementation of measurements using both platforms and the subsequent evaluation.
