Home security system
Martínek, Marek ; Dosoudilová, Monika (referee) ; Zuth, Daniel (advisor)
The introductory chapters of this work are dedicated to types of object protection, describe the elements of the security systems and the types of sensors that are present in the security systems. The next chapters deal with detectors of other hazards rather than crime and deal with the problem of signal transmission. At the end of the thesis, security system for house or apartment is solved, based on open-source solution in development environment ARMmbed.

Examples in environment ARMmbed
Maraczek, Patrik ; Marada, Tomáš (referee) ; Zuth, Daniel (advisor)
The bachelor’s thesis contains basic information for working with microcontroller properly in ARMmbed integrated development environment. Thesis describe microcontroller, microchips, chip’s periphery, ARMmbed environment. Also manual is written for this environment. Four examples are solved at the end of thesis to explain how extended devices and sensors are working. Devices like 4-bit seven-segmented display, LED diodes, ultrasound sensor SRF02.

Inverted pendulum realization based on Cubli
Ježek, Michal ; Zuth, Daniel (referee) ; Marada, Tomáš (advisor)
This master thesis deals with the development and construction of the inverted pendulum, inspired by the Cubli project. The objective is to develop and design an inverted pendulum, in the shape of one side of the cube balancing at one of its corner and for balancing is used the flywheel. For its design 3D printing is used to the maximum extent and as the electronic parts commonly available components at an affordable price are used. The design of the construction and the components allow the construction of a complete cube, without the need of further development or fundamental changes in the design of the model. For the calculations and the design of the controller the Matlab / Simulink software was used. As the controller algorithm the LQR algorithm is used with added integral feedback, to minimize control error. The 3D models of the single parts are created with FreeCAD software and printed on a 3D Prusa i3 MK2S printer.

Real-time Control of Ball on Wheel Model
Krejčí, Roman ; Otava, Lukáš (referee) ; Hynčica, Ondřej (advisor)
This diploma thesis deals with control the Ball on the wheel system in real time. In the first part there is made mathematical model of system, which is described by state equations. Then the laboratory model of Ball on the wheel system and its parts are described. The laboratory model consists servo drive, servo amplifier, microcontroller with real-time operating system and distance sensors. In the practical part of the thesis there is designed control of system by linear quadratic regulator and its implementation with control peripherals into microcontroller with real-time operating system. Ball on the wheel system is controlled by microcontroller, which sends a commands to servo amplifier by CAN bus.

Wireless sensor for indoor monitoring
Partika, Marek ; Jirgl, Miroslav (referee) ; Hynčica, Ondřej (advisor)
The work deal with programming interface for sensors and wireless transmission of the data. Communication with the sensor is solved by SPI and I2C protocol. For programming interface is used object-oriented programming techniques language C++. The wireless transmission of data is used XBee RF module. Here is proposed solution the correct format of data ready for send and method itself sending data. Data are received and displayed in the final application in the PC that is also able to send the selected data to the web, where data are displayed online.

Electronics circuit board and control software design for autonomous mobile robot
Meindl, Jan ; Krejsa, Jiří (referee) ; Věchet, Stanislav (advisor)
The master's thesis deals with the design and realization of embedded control system and software of the autonomous mobile robot DACEP. The research section focuses on the selection of sensory equipment. Moreover, the design of the embedded control system and the communication interface between this system and the master PC is described in detail, followed by the design of localization and navigation software that uses ROS framework. The section is written as instructive as possible for the development of robots of similar construction. Finally the development of a graphical interface for robot diagnostics and remote control is depicted.
