Fiducial Marker-Based Localization System
Hála, David ; Horeličan, Tomáš (referee) ; Gábrlík, Petr (advisor)
This work deals with localization of the robot in space using optical markers. In the first part of the thesis, the reader is introduced to the problems and pitfalls of this project and all the important connections, both mathematical and physical, are explained. The second part then focuses on the description of the procedure that was chosen to design the program and the ideas that led to its completion.

Visual-inertial odometry for UAV stabilization
Pintér, Marco ; Janoušek, Jiří (referee) ; Marcoň, Petr (advisor)
This master's thesis deals with the development of a system for estimating the position of an unmanned aerial vehicle in space without using GNSS (Global navigation satellite system). Visual and inertial data are employed for the position estimation of the unmanned aerial vehicle in space. The thesis describes various methods of determining the position using visual and inertial odometry. In the subsequent part of the thesis, the selection of a suitable camera sensor and onboard computer is discussed. The choice of an appropriate operating system, ROS (Robot Operating System) distribution, and a suitable algorithm for processing visual and inertial data is also described. To acquire telemetry data and basic control of an unmanned vehicle in space, a ROS node was implemented, which was tested in the Gazebo simulation environment with PX4-SITL. With the designed system experiments of comparing the accuracy of position determination against GNSS was done in real enviroment. From the achieved results, it can be concluded that visual odometry achieves very good results compared to GNSS.

Object Detection on Robotic Workplace Using Two Kinects
Dragúň, Peter ; Beran, Jan (referee) ; Rozman, Jaroslav (advisor)
This thesis deals with the use of a multi-depth camera Microsoft Kinect V2 for object pose estimation. The main emphasis is on calibration, including mutual and also calibration of a single camera. Which is critical for correct transformation. The theoretical part thesis describes methods for object detection and their pose estimation in space using the robotic operating system. The practical part thesis describes resolving issues with USB saturation by adding a single board computer based on ARM architecture for secondary Kinect.

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.

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.
