Embedded System for Water Level Monitoring
Hanák, Jiří ; Kašpárek, Tomáš (referee) ; Šimek, Václav (advisor)
This work is dealing with the design and implementation of an embedded water level monitoring system. The purpose of the system is to control the filling of a tank based on the water level. First of all, the attention is given to the survey of existing measurement techniques and selection of the appropriate sensing elements for a given scenario. In fact, the embedded system is using TFmini and JSN-SR04T-2.0 contactless sensors. The system is controlled by STM32F0 microcontroller from STMicroelectronics programmed in C using HAL abstraction layer. The measured results are sent via Wi-Fi SoC ESP8266EX to the Python server that is used for processing and demonstratiton purposes.

Autonomous mobile robot
Pijáček, Ondřej ; Kopečný, Lukáš (referee) ; Jílek, Tomáš (advisor)
This thesis describes the design and implementation of chassis for autonomous wheeled mobile robot along with a proposal for a suitable control system. To move the robot was necessary to create individual modules for measuring environmental data, its subsequent processing and power management. For the entire robot system capable of rapid interaction, certain tasks are separated and controlled by its own microcontroller. For communication between the modules were chosen and designed SPI bus communication protocol. Thus assembled chassis then communicates over a serial line with higher system from which acquires data indicative of a subsequent procedure. The result is a controlling system communicating between its parts. Part of the design is also defined communications protocol that transmits data on the one hand and also used for fault diagnosis when sending information. Furthermore, there are patterns and specific methods for controlling the individual modules. In conclusion, the thesis described the proposed testing the robot in real conditions, along with the measurement results obtained in the task of autonomous driving.

Measuring and Visualizing Distance Sensor Data in Real-Time via Arduino and Xbee wireless communication to Matlab
Zapletal, Marek ; Liška, Radovan (referee) ; Karakhalil, Mourad (advisor)
Work describes making of measuring system consisting of ultrasonic sensor, programmable board Arduino, where the wireless communication is provided by Xbee modules. Theoretical part depicts the single components including the programmes for making the code necessary for proper function of the system. On the other hand, realization and creation of programmes is the centre of practical part of the work. System was physically made and the obtained data from distance sensor were in real-time transferred and depicted in MATLAB programme, where the data are filtered and the graphs of elapsed time- distance are drawn. This work is one of the first possible steps in making intelligent devices or robots from the general aspect of mapping, navigating and orienting in a surrounding area.

Use of Single-Chip Microprocessors AVR ATMEL for Measurement of Distance
JŮZA, Zdeněk
The bachelor's thesis deals with the construction of a measuring tool that will probably enable substitution of the vernier scale in manually controlled machine tools. It also treats a possible use of the AVR ATMEL circuit for these applications. The sensor used for measuring the distance is the magnetic linear encoder AS5311. The thesis also presents the analysis of a prototype design using an AT MEGA 32 microcontroller and a AS5311 sensor . The output of the measuring device is displayed on a LCD display.
