Infant Movement Monitor
Zahradníčková, Ludmila ; Chmelař, Milan (referee) ; Sekora, Jiří (advisor)
Movement monitor is a detection device for monitoring the frequency of breathing of newborns and infants. It is usually indicated to children under the one year as a support to reduce the risk associated with sleep apnoea and Sudden Death Syndrome. The theoretical part of this bachelor thesis discusses the physiology of respiration, respiratory disorders, methods of monitoring and treatment. The aim of the technical part is to design own monitoring device for detecting and evaluating the frequency of breathing. It includes a block diagram and a wiring scheme of device and a flow chart of program, which is implemented by a microcontroller.

Two legged walking robot
Kraus, Václav ; Háze, Jiří (referee) ; Šteffan, Pavel (advisor)
The aim of this work is to present the topic of walking robots, the design and construction of a two-legged wirelessly controled robot. The work is divided into two parts. The first one is theoretical. It addresses the possibilities of sensorics and wireless communication technologies, which are used in robotics. The second part includes the robot's design of construction, walking and electronics. The output of this work is the robot construction, which is controled using a computer application via wireless technology WiFi.

Draft sources 1000A AC current sensors for calibration
Klimeš, Jan ; Vetiška, Vojtěch (referee) ; Dohnal, Petr (advisor)
This bachelor thesis deals with design and construction of device for precise measurement of 1000 A alternate current. This thesis theoretically discusses the possibilities of conventional solutions, such as current transformers, as well as modern methods in the form of current sensors. The output of this thesis is a solution of problems with accuracy and discussion of other possible ways to reduce systematic error. The thesis discusses structure of the current transformer, the digitalizing of the signal and its usage as an input for engineering units. The device is then tested for final accuracy.

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..

2D ultrasonic positioning
Junek, Jiří ; Šťastný, Ladislav (referee) ; Hynčica, Ondřej (advisor)
This thesis deals with the implementation and evaluation of measuring directional and omni-directional ultrasonic senzors. Control of ultrasonic senzors and computation of a distance is realized by using a microrontroller Arduino Duemilanove. The first part deals with the measurement of directional sensors, their wiring and subsequent processing of the measurement is performed in Matlab. The second part deals with solving of measuring and visualization 2D position omni-directional ultrasonic senzors, implementation trilateration algorithm for calculating x and y coordinates and comparison the used filters. At the end of this thesis also includes a comparison of directional and omni-directional ultrasound and evaluate their applicability for measuring 2D position.
