MIDI to DMX signal converter for synchronizing stage lighting with live music
Hajdúch, Patrik ; Záviška, Pavel (referee) ; Sikora, Marek (advisor)
This bachelor thesis focuses on designing a device for converting MIDI signals to DMX signals. The converter runs on the ATmega328P microprocessor with the Arduino bootloader and is capable of converting Note On, Note Off, and Control Change messages into changes in the DMX output signal. For the conversion, a map consisting of three profiles is used, which is editable using a desktop app and saved on an external EEPROM. This allows the converter to be used universally with many different DMX systems. The device is housed in an enclosure with dimensions that allow it to be stored within a single rack unit. The converter allows for fully automatic control of stage lighting and other stage equipment in synchronization with music and creating complex scenes using the widely used MIDI protocol.

Controlling LEGO Powered-up Hub from EV3
Potoček, Jakub ; Polčák, Libor (referee) ; Hranický, Radek (advisor)
This work deals with the communication between two incompatible programmable LEGO bricks, the LEGO Mindstorms EV3 and the LEGO Control+ Technic Hub. The task of this work was to create a communication interface enabling the transfer of data between these two bricks and thus enable the EV3 brick to send and possibly also receive data from the Technic hub brick. During the creation of this work, I designed and constructed two prototypes using an optical interface for data transmission. The second prototype enables two-way communication. This enables data from sensors and function return values to be transferred to EV3. Despite the fact that the resulting solution does not allow fast enough data transfer due to the technical limitations of the Technic hub brick, this solution is suitable for use by owners of these LEGO building blocks looking for ways to use both bricks when creating models.

Controlling LEGO Technic Active Elements from EV3
Blaško, Daniel ; Polčák, Libor (referee) ; Hranický, Radek (advisor)
LEGO Mindstorms je populárna rada programovateľných kociek s rozsiahlou sadou funkcií, ktorá už 25 rokov pomáha učiť deti základy robotiky a počítačových vied, a ktorá sa teší širokej komunitnej podpore. Cieľom tejto bakalárskej práce je vytvoriť hardvérové a softvérové riešenia, ktoré zlepšia kompatibilitu medzi kockou Mindstorms EV3 a ostatnými motorizovanými LEGO súčiastkami, s primárnym zameraním sa na produktovú radu Power Functions. V rámci tejto práce boli v rôznych iteráciách vytvorené radiče, ktoré rozširujú možnosti kocky EV3 ovládať motory, s použitím vlastných návrhov dizajnov plošných spojov a 3D tlačených puzdier. Okrem nich boli vyvinuté softvérové kódovacie bloky, ktoré umožňujú kocke komunikovať s týmito radičmi a ďalšími UART zariadeniami.

Embedded Control of Non-Contacting Waveguide Sliding Short
Horvát, Martin ; Pánek, Richard (referee) ; Strnadel, Josef (advisor)
Táto práca sa zaoberá návrhom a implementáciou softwarového riadiacého systému pre bezkontaktný nastaviteľný vlnovodový skrat použitím krokového motoru. Predstavuje návrh systému ktorý podporuje implementáciu ľubovolného komunikačného protokolu, a ktorý môže byť použitý s ľubovoľným krokovým motorom. Predstavený návrh bol implementovaný na mikrokontroléry Texas Instrument AM243x Sitara, využitím operačného systému reálneho času FreeRTOS. Systém podporuje komunikáciu cez automatizačný protokol EtherNet/IP, a cez prispôsobený seriový textový protokol využívajúci UART. Systém bol testovaný a vyhodnotený pomocou testou presnosti pozície, reprodukovatelnosti pozície a testom fázového posunu odrazenej vlny.

Návrh algoritmu jízdní stability pro laboratorní model vozidla
Šulc, Michael ; Vejlupek, Josef (referee) ; Grepl, Robert (advisor)
This Master's thesis deals with a research study in the area of modelling the dynamics of a four-wheel drive (4WD) and four-wheel steer (4WS) vehicle, including a tyre model together with the design of vehicle stability control algorithms. The work also includes making the necessary modifications to the experimental vehicle, including the design of new control electronics. Based on the proposed dynamic model, the estimation of the necessary vehicle parameters is carried out. On the simulation model, ABS/ASR driving stability algorithms are designed, which are than implemented on the experimental vehicle.

DMX 512 protocol analyzer for personal computer
Vahalík, Jiří ; Sysel, Petr (referee) ; Krajsa, Ondřej (advisor)
The bachelor thesis deals with the design of a DMX converter for a personal computer. The theoretical part summarizes the DMX, RDM and Art-Net protocols and other commonly used communication protocols used by microcontrollers. In the practical part, a device circuit is fabricated, which is subsequently processed as a printed circuit board. In the last part of the thesis, programs are designed to ensure the functionality of the whole converter.

Design and realization of a developement board for BeagleBoard
Ťapucha, Andrej ; Hanák, Pavel (referee) ; Krajsa, Ondřej (advisor)
Contents of the thesis is to design and create an expansion board for the BeagleBoard computer one plate . The first and very important part was to find out all the possibilities for an extension of the computer itself . Choose the right expansion port . To study the possibility distribution of individual pins . Followed by the appropriate extension election districts that demonstrate the function of each enlargement . Test was designed PCB that contains circuits that change the voltage level of the BeagleBoard to protect a mini computer to the testing of each gusset periphery prevent damage to itself or part of the BeagleBoard . The peripherals themselves bind different parts of theoretical introduction. More specifically the extension of the LCD display is selected segment and includes two lines of 16 characters . When the possibility to add additional components were necessary to deal with the shortcomings of the output pins , this problem was solved by using an expander . He extends itself BeagleBoard by another 16 pins . On these pins are connected together on the LCD matrix keyboard . The creation of the board are two circuit temperature sensors , but have a different type of communication using I2C and one second using 1 -Wire bus . The board also contains various other bus outputs , for example, UART bus. It also contains an output pin which can be controlled PWM modulation . The remaining pins are versatile GPIO pins which can be programmed to define a function using the Linux operating system . The result is a final board of the package control programs which make it possible to verify the individual peripherals.
