Measurement of GNSS receiver accuracy
Čepl, Miroslav ; Gábrlík, Petr (referee) ; Jílek, Tomáš (advisor)
In this thesis a new method of determining an accuracy of a GNSS receiver is presented. First, a research of basic GNSS systems and a description of receiver accuracy is performed. Subsequently, the method of measuring the accuracy with the focus on RTK mode is proposed. A measuring jig is designed and manufactured. After verifcation of jig accuracy, a measurement of three dierent antennas is performed for subsequent comparison of basic characteristics. The work also contains instructions for operating the measuring jig.

Development of mobile robot autonomous docking
Čepl, Miroslav ; Věchet, Stanislav (referee) ; Krejsa, Jiří (advisor)
This thesis implements solution for automatic docking for a mobile robot using visual markers. After initial survey of already implemented works, new docking solution is proposed. Feasibility of the solution is verified with tests of marker detection precision. The implementation is tested in a simulation and with a real robot. The functionality of the proposed solution is verified by long-term tests. The result of this work is robot’s ability to navigate known environment to find and dock a charging station. After charging the robot is able to safely disconnect from the station.

Design and implementation of the LCD display drivers for Raspberry Pi
Cepl, Miroslav ; Lattenberg, Ivo (referee) ; Krajsa, Ondřej (advisor)
The aim of the course work is to design and implement a driver for touchscreen LCD display. The premise of the connection the display to the microcontroller using the I2C bus and use MCP23017 circuits. Raspberry Pi B + will be used for communication with circuits MCP23017 via I2C bus. Display TFT_320QVT will be connected to the outputs of extension circuits MCP23017. Part of the display complete is also a touchscreen with XPT2046 controller. Raspberry Pi runs on Raspbian system based on the Debian Linux distribution. The driver will serve to communicate and display information on the screen. The complete will be useable for applications such as selecting settings and show main information on the display.

Design of mobile robot simulation model suitable for ROS framework
Čepl, Miroslav ; Vojáček, Zdeněk (referee) ; Věchet, Stanislav (advisor)
This thesis focuses on motion models of autonomous robots. In the first section the framework ROS is introduced and creation of models for this framework is mentioned. The second section focuses on various types of robots and discusses their suitability for the framework ROS. Basic kinematic models for the most common robots are shown. In the third section a particular chassis is chosen, a motion model is experimentally determined and the results are tested on a control set of data.
