Localization system for mobile robot B2
Korytár, Lukáš ; Věchet, Stanislav (referee) ; Krejsa, Jiří (advisor)
The master’s thesis implements localization and navigation routines for mobile robot B2 in order to operate autonomously in an environment described by a road map only. The ROS framework was used for developing new software. The research part describes possible approaches to localization problem and summarizes ROS packages with localization and navigation software. The following part includes communication with the robot’s sensor modules and data processing from LIDAR, IMU and camera. The localization package robot_localization based on Kalman filter is implemented and setting of the navigation stack navigation is proposed, aiming to robot’s autonomous outdoor navigation. Implemented functions were tested in park environment and they are evaluated in this master's thesis too.

Tabletop Object Detection
Timko, Martin ; Veľas, Martin (referee) ; Kapinus, Michal (advisor)
The aim of this thesis is to design and create a module for robotic platform PR2. This module has to detect objects in front of the robot on a table and enable various operations with these objects. This thesis describes methods of object detection which were used in the implementation of the module. The thesis also describes the methods used for design and implementation of this module. The module testing and evaluation of results are mentioned at the end of the thesis.

Docking Station for Automatic Charging of Batteries of Robot
Beran, Jan ; Janoušek, Vladimír (referee) ; Rozman, Jaroslav (advisor)
The aim of this thesis is to create a functional docking and charging system for the Trilobot robot, which is improved and modified for use in future projects as a part of this thesis. The theoretical part discusses the path planning methods, battery types and charging methods, types of docking stations and the charging method itself. Also, a robot refurbishment design is presented, which is then implemented, along with the docking station. The refurbished robot has functional control software in the ROS framework, which allows it to perform not only the task of autonomous battery charging. In this thesis, a test of the whole system is also performed and the results are evaluated.

Augmented Reality for Desk Games and Educational Applications
Záleský, Jiří ; Kapinus, Michal (referee) ; Beran, Vítězslav (advisor)
This bachelor thesis deals with the topic of augmented reality and its use for board games and educational applications on the interactive table. The goal was to create a stand-alone system for an easy interactive game table creation, by designing a system that allows communication with the interactive table and the creation of a demo-application that presents the functionality of the system. In the system design section, the technologies and tools used, such as C ++, Qt, or Catkin, were introduced and the first design of the game - demo-application was created. The implementation section explains how to transform the design into a functioning application, and includes a description of the internal structure of the application. The last part of the work focused on testing brings, in addition to revealing the application errors, other suggestions for its expansion in the future. The result of the work is a functioning system for augmented reality and demo-application for it, which in the future will help to create other programs for an interactive table. The system is designed for use on the interactive ARTable3 table.

User Interface for Ground Vehicle Control in Outdoor Environment
Pavlenko, Peter ; Materna, Zdeněk (referee) ; Beran, Vítězslav (advisor)
This bachelor thesis includes design and technical aspects of GUI specific focused on remote control of ground robot in outside enviroment. The theoretical part deals with creating applications for the android platform and it takes a closer look at method of controlling the robot using the Robot Operating System. Main part of this thesis is the design and the implementation of application capable of navigation and control the robot. In conclusion you can find the testing done to verify validity of this graphic user interface.

Robot Localization Using Camera
Heřman, Petr ; Španěl, Michal (referee) ; Beran, Vítězslav (advisor)
The objective of this work is to design a simple localization method and its implementation in robot operating system ROS. This method uses a monocular camera as the only sensor and estimates the position in a known map. In experiments with prototypes are tested key points of type SURF, SIFT and ORB.

Control of Robot Manipulator Using Augmented Reality and Tablet
Pristaš, Martin ; Musil, Petr (referee) ; Beran, Vítězslav (advisor)
The aim of this thesis is to create an experimental application for manipulating virtual objects in the augmented reality using an tablet for controlling the robotic arm. There is created various ways of manipulating virtual objects for their translation, rotation, and scale change. These methods are tested on several users and compared within their usability. The application allows you to send the position of virtual object changes to the PR2 robot arm and simulate manipulation of virtual objects with augmented reality.

Robot Control with Voice Commands
Hájek, Pavel ; Kapinus, Michal (referee) ; Španěl, Michal (advisor)
This bachelor's thesis describes design and development of a robot voice control application aiming at platform PR2. It explains the procecess of voice recognition and describes the robot operating system as a target platform. The application uses library Sphinx-4 to translate speech to text, which is than published in ROS. In the end, the set of tests is described. Tests discovered, that the best way to control robot with a few simple commands is developing own grammar.

Path Planning using Voronoi Graphs
Živčák, Adam ; Uhlíř, Václav (referee) ; Rozman, Jaroslav (advisor)
The main purpose of this bachelor thesis is to design and implement plugin for robot operating system, which will be used for path planning using Voronoi graphs. Path planning is executed in well known world, about which robot knows where obstacles are placed. Thesis contains overview of main concepts of robot operating system, description of Voronoi graphs and algorithms to construct them. In conclusion is placed comparison of implemented plugin for path planning with ROS integrated planners.
