Processing of localization data and its accuracy
Návara, Marek ; Baránek, Radek (referee) ; Jílek, Tomáš (advisor)
This work is focused on correction of localization data, relative to them location of the sensor on robot. Also solves the conversion between coordinate systems WGS-84, ETRS-89 and local coordinate system. For localization data are designed error characteristics and their transformation.These points have been implemented in C#. Classes were firstly developer for single-axis sensors and they are base for multi-axis sensors. The implementation has been tested on simulated data and verified in the experiment with the robot envMap. Experiment results show that the correction is implemented properly and can be further used. Error characteristics listed in the work characterize the measurement uncertainty of location data and can be used in further processing.
3D LED cube
Rak, Jan ; Jílek, Tomáš (referee) ; Florián, Tomáš (advisor)
The goal of this project is to design and construct a LED cube for visualization and imaging attract attention. With respect to the assignment was determined resolution 8x8x8. For the overall management and communication with the PC was chosen development board STM32F4 Discovery, which, thanks to it parameters, is sufficient for this application. Cube consisting of diodes and power wires will sit on the governing board, which will include all parts of management and communication, including the controller power supply. The board will be covered by colored fabric for a better look.
Processing of localization data and its accuracy
Návara, Marek ; Chromý, Adam (referee) ; Jílek, Tomáš (advisor)
This work is focused on correction of localization data, relative to them location of the sensor on robot. Also solves the conversion between coordinate systems WGS-84, ETRS-89 and local coordinate system. For localization data are designed error characteristics and thier transformation.These points have been implemented in C# as individual classes for position sensors and sensors orientation. Classes were firstly developer for single-axis sensors and they are base for multi-axis sensors. The implementation has been verified in the experiment with the robot envMap. Experiment results show that the correction is implemented properly and can be further used. Error characteristics listed in the work characterize the measurement uncertainty of location data and can be used in further processing.
Odometer module for mobile robot
Davídek, Daniel ; Burian, František (referee) ; Jílek, Tomáš (advisor)
The main objective of this work was the development and realization of odometric module for mobile robot envMap. The module processes signals from the incremental encoder and then calculates the position and direction of the robot together with the probability of its occurrence. The calculated data with a time stamp obtained from the GPS, are then sent to the above-system via the serial interface. For the realization the development board STM32F407G was chosen. f this board can be configured to function as an encoder input. This minimizes the possibility of encoder data loss when external interrupts are handled. The STM32F4 will not be any pull-back in the later development as there are plenty of peripherals on STM32F4. They were designed with two printed circuit boards: the reduction for the GPS module and shield-board for STM32F4. The equations for calculating odometric information and the probability of occurrence are included in this work. To calculate the movement of the robot, the equation considering only the movement on the plane surface is chosen. Later in this thesis there is also description of the source code for the STM32 and its functionality. In the results there is a complete connecting diagram along with the description of the utility program ODOMAT and communication messages. Finally, measurements correcting systematic error in parameters of the robot are described and there is the final odometry measurements compared with GPS localization as ground truth.
Electronic Subsystem of a Small Mobile Robot
Podolan, Luděk ; Jílek, Tomáš (referee) ; Žalud, Luděk (advisor)
The topic of this bachelor thesis is design and construction of a mobile robot with wheeled differential platform. The main goal was to design, implement and test an electronic sub-system for a small mobile robot. Each chapter firstly deals with theoretical aspects of relevant topics and after that describe the process of construction. The thesis shows various ways of construction of the robot with the process of selection of the optimal one. The main controlling part of the robot is the AVR microcontroller placed on the EvB4.3 development board. A simple menu was created on an LCD display for communication between the user and the robot. Battery management is controlled by an analogue to digital converter. The last two chapters focus on encoders and communication between the robot and a proximity sensor. Pictures of the robot are enclosed at the end of the thesis.
Control of EUROBOT Mobile Robot
Plucnar, Libor ; Jílek, Tomáš (referee) ; Žalud, Luděk (advisor)
The thesis is focused on the theoretical development of a control algorithm for mobile robot based on Eurobot and its subsequent practical implementation according to a specific assignment. There are two main methods designed to control the robot according to the input signal, whereby the robot orientats. The first control method is using the camera. This section describes general procedure how to create the image classifier, under which it is possible to search objects. The second part describes the trajectory planning of the robot depends on its position to achieve a specific point on a predetermined map. During the proceedings are taken into account static and dynamic barriers that can occur in an environment in which the robot moves in. In the study was also designed graphical user interface.
Windows 10 IoT on Raspberry Pi 2 computer
Prachař, Vojtěch ; Jílek, Tomáš (referee) ; Jelínek, Aleš (advisor)
The purpose of this thesis is to learn about the Raspberry Pi 2, Windows 10 IoT and development tools for this platform. In this work is presented hardware and software, and stated in detail the launching of development tools. In next part some sample applications and communication protocols are tested. In last part tested important ports for robotics. At the end, this platform is evaluated for the possibility of usage in home automation and robotics.
ARM Remote debugging over industrial bus.
Skalický, Jakub ; Jílek, Tomáš (referee) ; Burian, František (advisor)
This semestral thesis is concerned on facilities of using DebugMonitor exception for debugging software which run on ARM Cortex-M4. The comunnication between debugged software and debugging master is implemented via CAN bus. The result is support for debugging without special debugging equipment. For support of this type of debug this thesis implemented code library called SDebug. It's managing parts of Cortex-M4 core, which are userd for debug.
Evolutionary Design of Artificial Neural Network
Jílek, Tomáš ; Šperka, Svatopluk (referee) ; Pospíchal, Petr (advisor)
Focus of this bachelor thesis is on Neural networks, Genetic algorithms and Evolutionary Design. First part of thesis describes Neural networks, their history, training and ways of use and Genetic algorithms, their components, operators and practical application. Next part is devoted to prediction of time series, specifically prediction with use of Neural networks. This is followed by practical part of work, implementation of experiments with Evolutionary design of Neural networks for prediction in which currency exchange rates of several countries are used as a predicted time series. Results and discussion about further development of thesis are described in last chapter.
Electronic Navigation System
Jílek, Tomáš ; Straka, Martin (referee) ; Šimek, Václav (advisor)
The aim of this thesis is the design and realization of Electronic navigation system. It comprises magnetic senzors and GPS receiver which enables to get information about movement and its direction.
