ECG data recorder
Hruškovský, Antonín ; Krajsa, Ondřej (referee) ; Burda, Karel (advisor)
The master thesis deals with the issue of long-term ECG recording, used in medicine for monitoring of cardiac anomalies. Author focuses on explaning the general concepts in the first part. Author describes measuring methods and issues associated with measuring. Comparison of existing devices and design of solution with own features are in next chapter. Next is comparison and selecting of formats for recording measured data and description of device connectivity. In next chapter author focuses on hardware design and implementation of device. After that author describes software solution design for microcontroller, Bluetooth module and smartphone. Author introduces possible improvements for future generation of the device and then describes results of testing at the end of this work.

Hybrid Control System for Quadrocopter
Sojka, Stanislav ; Mlích, Jozef (referee) ; Dittrich, Petr (advisor)
This thesis deals with the design and theoretical description of the hybrid control system for quadrocopter. First, a mathematical model is presented, sensors needed for development and their principles. This work shows the system architecture design and scheme of communication channels between the blocks. Implementation section discusses specific uses of computing nodes/sensors and their settings. In this thesis there are illustrated messages sent between computing nodes and the control loop machine. It also describes how to test the sensors, measurement results and techniques for improvement.

3D controller
Hrubý, Lukáš ; Fujcik, Lukáš (referee) ; Bohrn, Marek (advisor)
The following work deals with problems of scanning of device position in space, processing of collected data about its position and sending these data to end device. In scope of this work will be created special controller which will use accelerometer, gyroscope and magnetometer to scan its actual position in respect to Earth and it will wirelesly send its position to controlled device. Individual components for proposal will be chosen based on previous experience and available documentation.

Robot Controlled by PIC Microprocessor Unit
Heřman, Petr ; Luža, Radim (referee) ; Rozman, Jaroslav (advisor)
This thesis describes design of a cheap robot. It includes implementation of firmware of low level control unit based on microcontroller PIC. The firmware drives motors, gains sensors data and communicates with the high level control unit. Furthermore the thesis presents realisation of connection to the robotic operation system ROS and its standard structures allowing usage of existing packages for the robot teleoperation and displaying sensor data on the remote computer. The thesis finally reports experiments with the robot. The constructed prototype is the model of the robotic lawn mower, however the whole solution has universal usage.

Řezníček, Pavel ; Dlugoš, Jozef (referee) ; Zháňal, Lubor (advisor)
This diploma thesis deals with possibility of using a mobile phone to measure vehicle dynamics and determine the accuracy of this measurement. In the research part, it is first mentioned what methods are used to produce sensors for mobile phones. Next, a description of individual sensors that can be used for vehicle dynamics measurement, the principle by which the sensors record measured values and their inaccuracies. The practical part shows with which professional device the accuracy of the mobile phone is compared, how data can be collected from both devices and how the comparison measurement was performed. This section also describes the ways in which the measured data of the mobile phone can be improve for better accuracy, and finally the comparison of the measured values from both devices from different points of view.

New features for real-time positioning system locator
Studený, Jakub ; Sekora, Jiří (referee) ; Kolářová, Jana (advisor)
The diploma thesis deals with the detection of falls and impacts, based on data obtained from inertial sensors, and by measuring the distance using a laser. The aim of this thesis is to extend the functionality of locators from Sewio. The thesis describes the procedure for designing algorithms for detection of falls and impacts. Then there is a procedure for development of hardware and software solution, for laser distance measurement by locator, together with presentation of achieved measurement results realized by locator after implementation of proposed solution. The work also emphasizes the minimization of energy consumption of individual solutions. In conclusion, there is a discussion of achieved results with evaluation of efficiency and usability of proposed solutions.
