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.

Mobile robot control system
Bugár, Loránt ; Jílek, Tomáš (referee) ; Hynčica, Ondřej (advisor)
Bachelors project is fixated for creating a mobile robot with a real time operating system. The robot control system is based on a microcontroller Arduino with ARM Cortex-m3 processor. The practical part is dealing with resolving the client-server communication with the UDP protocol, also with the identification of the engine from measured data’s by the Simulink and subsequently designing the PI regulator from the identificated data’s. In he last part of the work the focus is giving to solving the communication with I2C bus and using sensors like : accelerometer, ultrasonic sensor, infra sensor, light sensor, hall sensor and usage of a robotic arm. An application is created for controlling the robot and for visualisation of sensor readings..

Modular Power Supply for Formula Student
Ščípa, Samuel ; Bohrn, Marek (referee) ; Pavlík, Michal (advisor)
This bachelor thesis is focused on the theoretical analysis and design of switching power supply with galvanic isolation. The implementation of the design is in the form of the power and control part of the modular power supply. The device parameters are suited for the needs and requirements of the development department of the electric student formula. Design configuration achieves a maximum output voltage of 1000 V and a current of 100 mA, which are user-adjustable.

Automation of RC Models Control
Vávra, Jan ; Musil, Petr (referee) ; Zemčík, Pavel (advisor)
This thesis is about controlling RC model with microcontroller ESP-32 through WiFi enabled mobile device with OS Android. Goal of this thesis is to make controlling RC model easier and more fun. Parts of this thesis are dealing with using pulse width modulation to control servos, creating a user interface and making a protocol for comunication between RC model and mobile device. Result of this work is application on OS Android, which sends instructions on microcomputer, that controls steering servo and elecromotor. System has predefined stunts on microcomputer and operator has a choice of defining custom stunt in application, which is send to microcomputer in series of individual instructions.

Universal control unit of technological processes
Gogola, Marek ; Vlach, Radek (referee) ; Krejčí, Petr (advisor)
This diploma thesis is about design and realization of universal control unit of technologic processes in food-processing industry. The main goal of this work is to create a device, which will be able with respect to desired values and using measured data autunomusly regulate output. In this work was done the realization of the control unit both from hardware and software aspect. Designed control unit is able to change the output power according to measured temperature. Furthermore is able to control of 2 relays. To set up the desired values and control of relays is used PC software.

Supporting algorithms for electrical motor control
Řezáč, Martin ; Buchta, Luděk (referee) ; Blaha, Petr (advisor)
This thesis is focused on a creating supporting drivers and algorithms for electrical motor control using CPU TriCore TC275 CA. The first part is devoted to processor description and selected peripherals, which are A/D converter, a timer for creating the PWM signals and the second timer for processing singnals from encoder. All drivers are tested on an aplication kit, which is equipped with TC275 CA processor. The second part analyzes the measurement quality of GMR sensor TLE5009. Special testbench was prepared for sin cos data capturing and for their comparison with precise encoder position measurement. It was composed from DC motor having both sensor types on commons shaft. Data are acquired using LabView. Subsequently, it analyzes the sensor data, their compensation and subsequent comparison with measured data from the encoder.
