Control System of Small Mobile Robot
Rysnar, Jiří ; Florián, Tomáš (referee) ; Žalud, Luděk (advisor)
This master’s thesis elaborates on the control of a wheeled mobile robot and its sensor system. The sensors provide information about distances of obstacles in its surroundings and orientation in area. The communication is realized by radiomodems, commands and data are sent by serial link between microncontroller and the PC.

Measuring station firmware for wireless data collection via LoRaWAN
Jánoš, Vít ; Možný, Radek (referee) ; Juráň, Radovan (advisor)
This thesis deals with software development for STM32WL55-JC1 MCU. Development kit was chosen primarily bacause of its LPWAN possibilities. Final prototype communicates on LoRaWAN network. Data are sent through public network from The Things Network, these data are concentrations of carbon dioxide, temperatures and carbon dioxide flux. Data are also backed up locally on SD card along with timestamp. The software was designed with the use of the chamber measurement method in mind, which is also described in the text.

Control Unit for Autonomous Vacuum Cleaner
Matějů, Jan ; Kopečný, Lukáš (referee) ; Žalud, Luděk (advisor)
This paper is in introduction focused on review of robotic vacuum cleaning and evaluation of available products qualities. However the main focus of this paper is system design of all subsystems, control systems and PCD design of robot electronics. In this paper is also described a method for evaluating approximate distance of robot from the obstacle. There are also described problems of system design of IR proximity sensors. The last part of this work is development of control software for robot and its testing.

Robotic Manipulator Controlling Using Microcontroller
Zemánek, Martin ; Škarvada, Jaroslav (referee) ; Růžička, Richard (advisor)
This master's thesis deals with control robotic manipulator ROB 1-3 using common joystick and microcontroller HC08 NITRON or HC08 LJ12. The goal of this work was creation of module for controlling axes position of servos included in robot by analog signal coming from connected joystick. There are formed possible suggestions about connecting individual parts together for both autonomous and version using development kit. Programming code suggestion is based on these connections during further development. The limitations of using it are described in analysis and final results are shown in statistics results.

Electronic control of servomechanism for drive-simulator
Valouch, Martin ; Šebesta, Jiří (referee) ; Fedra, Zbyněk (advisor)
The aim of this bachelor´s thesis was construct electronic driving unit of positioning servomechanism in driving simulator. As controlling unit was chosen 8-bit microcontroller ATmega16 produced by ATMEL® and for scan actual angle of displacement the seat magnetic rotation encoder AS5040 produced by Austriamicrosystems®. For construction of bridge circuit were chosen MOS transistors. This transistors are excited by two Power MOSFET Drivers. Their job is convert output signal TTL logic from microcontroller to voltage in needed norm for transistors circuit closing. Data from PC in drive simulator can be transfer by serial interface RS485 or RS232.

Hardware Accelerating of Encryption Algorithm
Hradil, David ; Martínek, Tomáš (referee) ; Kořenek, Jan (advisor)
The goal of this thesis is to design a hardware realization of circuit which will implement the AES algorithm. A motivation was to make an acceleration against the classic software encryption. The acceleration is achieved by special designed parts of the circuit, which correspond to particular operations of the AES algorithm. First, there was necessary to design the circuit. In the next step there was a need to describe the designed circuit by the VHDL language. Then the circuit was simulated and synthesized. Due to comparing the circuit with software processing a software implementation was created. Both implementations were created for the FITKit platform. The hardware implementation is made by the FPGA technology and the software implementation is realized in a microcontroller. The result of the thesis is almost one thousandfold acceleration against the classic software encryption.

Control system for equipment using renewable energy sources
Novotný, Jan ; Bradáč, Zdeněk (referee) ; Benešl, Tomáš (advisor)
The work deals with design of power and control electronics for water micro source in island network. In the general part the readers are acquaints with the issue of renewable energy sources and describes commercially produced micro sources. The practical part deals with the design of its own control system and power electronics using its own control system or PLC for water micro source. The microcontrollers were used for the implementation of the control system, for which the program part was created.

Wireless security facility
Gargulák, Lukáš ; Morský, Ondřej (referee) ; Zeman, Václav (advisor)
The content of this thesis is the design, construction and programming of wireless security device. This wireless security system consists of two units. Personal unit and sensor unit. This thesis compares two ISM bands 433 MHz and 868 MHz. The thesis presents a selection of parts for construction wireless security device. The work also deals with the structure of transmitted frames on the link layer. Marginally are discussed ways to reduce consuption AtmelAVR microcontrollers and also two ways of charging Li-Ion battery. It also outlined the firmware of both units. Its complete source code is included on the DVD.

Stepper motor driver equipped with industrial communication
Nepivoda, Tomáš ; Baštán, Ondřej (referee) ; Arm, Jakub (advisor)
The main goal of this bachelor thesis is to design and realize driver for stepper motor, which could be controlled by supervising system using modern industrial communication network. The basis od this thesis is theoretical study on the subject of stepper motor drivers and industrial communication in the field of embedded systems. This theoretical study is then used for selecting the proper communication network and creating concept od the stepper motor. Thesis further describes design procedure and realization of hardware components and subsequent implementation of frimware. Last part of the thesis is dedicated to the creation of simple master device, which would be used for driver testing.
