Barcode scanner connected to a server database
Hrůzek, Jan ; Bastl, Michal (referee) ; Najman, Jan (advisor)
This thesis deals with barcode scanning on Raspberry Pi and subsequent work with server database system. There is a detailed analysis of principles of working of scanners and database systems and their selection for the purpose of this thesis. The settings and behavior under different conditions of the chosen scanner are analyzed and proper settings for different situations is suggested. Python is used as a programming tool, and a simple application for scanning and working with the database with a simple graphical interface, which was created as part of the work, is described along.

Klasifikace dat v obraze pomocí nástrojů pro strojové učení v jazyce Python
Voronin, Artyom ; Appel, Martin (referee) ; Bastl, Michal (advisor)
This thesis introduces the issue of data classification in the image using tools for machine learning in Python. The aim is to verify the possibilities of overtraining existing models on their own data and evaluating the efficiency and complexity of the entire process. Subsequently, the processing of the achieved results in the form of a demonstration task, image capturing by a web camera and classification of the object in the field of view.

Design and implementation of an ultrasonic sensor for the educational platform
Slabý, Vojtěch ; Bastl, Michal (referee) ; Spáčil, Tomáš (advisor)
Bachelor’s thesis is focused on a design, fabrication and implementation of an ultrasonic sensor module, which will serve for a distance measurement for an education developer shield based. This sensor should be used as an original module which fits in a requested size format. Now is used a sensor HC-SR04 which exceeds size and voltage needed for a module and uses an adapter, which is not rigid. Bachelor’s thesis is focused on a topic of a existing ultrasound principles and its function for ultrasound distance measurement and calculating necessary values. Thesis includes a list of existing solution for designing a monostatic or a bistatic transdcuers sensors. Our module is compared to those solutions and there is also an overview on a two most used methods for a circuit design which controls a transducer. You can find a designed circuits for creating a prototype PCBs, which heart is a microcontroler PIC16F1769. Programming is handled by a PicKit 3, MPLab X IDE in „C“ language. Communication with a Jobst shield is handled by SPI. Result of this thesis is a design, fabrication and use of two prototype PCBs. First PCB is not tied by a size request and serves for a basic circuit testing and basic distance measurement and the second PCB is in a desired size and serves for distance measurement testing and communication via SPI. These prototypes were fabricated and tested in a way to fulfill set task goals.

Development of database of mechatronic models in Simscape
Al-Dailami, Zaid Abdulqudos Abbas ; Najman, Jan (referee) ; Bastl, Michal (advisor)
Tato práce se zabývá především vývojem databáze modelů mechatronik v nástroji Simscape. Je rozdělena do tří hlavních částí a to následně: První část popisuje nástroj Simscape a jeho možnosti . Práce poskytuje návrh, jak nastroj použít při vývoji modelů a jak se liší od jiných způsobů modelování. Druhá část obsahuje některé mechatronické modely založené na Simscape. Některé z modelů jsou také vytvořené pomocí standardního modelování Simulinku, a ty lze porovnat s dříve uvedenými modely. Třetí část je zaměřena na jeden z dříve navržených modelů se stejnosměrným motorem. Tento model se používá k vyhodnocení, odhadu a optimalizaci skutečných parametrů stejnosměrného motoru, obsahuje také popis, jak vygenerovat c kód z modelů Simscape, abychom jej použili v HIL.

Design and implementation of demonstration model "double inverted pendulum"
Slabý, Vít ; Brablc, Martin (referee) ; Bastl, Michal (advisor)
This thesis describes the process of rebuilding an experimental model of a single pendulum on a cart into the double pendulum on a cart. The control algorithm in MATLAB/Simulink environment for stabilization of the pendulum in the inverse position is designed. For this purpose, LQR state feedback control was implemented. Also method for swinging the pendulum into inverse position from stable state (swing-up) was designed. Feedforward method was utilised for swing-up control. In the thesis, functionality of these algorithms is shown.

Design of device for voltage monitoring in the electrical network
Ženčár, Pavol ; Chalupa, Jan (referee) ; Bastl, Michal (advisor)
This thesis is about development of a device for monitoring and logging RMS value of voltage in main electrical network. Thesis consists of choosing the right electrical components, prototype testing , designing a printed cirquit board (PCB) and making a program code. We can divide the assigment to 3 major tasks , which are measured values data logging on SD card, printing of measured values on web server and transfering measured values through USB port.

Design of control unit for two-wheeled self-balancing vehicle
Bastl, Michal ; Klimeš, David (referee) ; Chalupa, Jan (advisor)
This diploma thesis is a part of a project of two students. The aim of the project is to design safer electronics for the unstable balancing vehicle HUMMER and implementation of advanced diagnostics and fault detection. In the first part of the project we analysed the original vehicle using the FMEA analyse and created a new concept of the vehicle. The second part of the project describes a new hardware. I designed and tested the power electronics, control unit and supplies. The outputs of the work are prototypes which allow testing a new concept.

Semi-solid alloys testing device
Valíček, Václav ; Bastl, Michal (referee) ; Chalupa, Jan (advisor)
This thesis deals with design of semi-sollid alloy testing device. In the beginning, there are briefly introduced possibilities of semi-solid alloy exporation followed by analysis of temperature measurement options, torque measurement options and control of the thermal system. There was build development version of construction and electronics based on results of analysis. The outcomes of this thesis are: design of printed circuit board based on electronics prototype connection, production of mechanical parts for device and realization of user interface in form of touch screen.

Assembling and creating tasks for an interactive robotic head
Szabó, Michal ; Formánek, Martin (referee) ; Bastl, Michal (advisor)
This bachelor’s thesis deals with the creation of the model of an interactive robotic head. The work itself is divided into two parts, theoretical and practical. The theoretical part is devoted to an overview of the types of robotic heads, a brief description of the available tools for recognizing objects in the image and tools for recognizing spoken speech in real time. The practical part is focused on the tools used in programming of this model, the electronics used and the resulting model of the robotic head. Finally, there are described programmed functions enabling various ways of the interaction with humans. The work includes function scripts programmed in Python.
