Navigation of B2 mobile robot in outdoor environment
Hoffmann, David ; Věchet, Stanislav (referee) ; Krejsa, Jiří (advisor)
This master’s thesis deals with the navigation of a mobile robot that uses the ROS framework. The aim is to improve the ability of the existing B2 robot to move autonomously outdoors. The theoretical part contains a description of the navigation core, which consists of the move_base library and the packages used for planning. The practical part describe the aws of the existing solution, the design and implementation of changes and the results of subsequent testing in the urban park environment.

Visual Car-Detection on the Parking Lots Using Deep Neural Networks
Stránský, Václav ; Veľas, Martin (referee) ; Rozman, Jaroslav (advisor)
The concept of smart cities is inherently connected with efficient parking solutions based on the knowledge of individual parking space occupancy. The subject of this paper is the design and implementation of a robust system for analyzing parking space occupancy from a multi-camera system with the possibility of visual overlap between cameras. The system is designed and implemented in Robot Operating System (ROS) and its core consists of two separate classifiers. The more successful, however, a slower option is detection by a deep neural network. A quick interaction is provided by a less accurate classifier of movement with a background model. The system is capable of working in real time on a graphic card as well as on a processor. The success rate of the system on a testing data set from real operation exceeds 95 %.

Interactive Interface for Robot Remote Control
Lokaj, Tomáš ; Beran, Vítězslav (referee) ; Španěl, Michal (advisor)
This work deals with the interactive interface for remote controlled robots and examines some of the existing visualization and simulation tools and robotic platforms. It also designs and implements interactive elements suitable for representation of detected objects, such as bounding box or billboard, and proposes interactive elements to eliminate some of the problems associated with remote control of the robot, such as bad perception of distances and the orientation in the environment. The interactive interface is implemented in the Robot Operating System using offered means for visualization, communication and operations management. Graphics primitives are represented by Interactive Markers that, in addition to the visualization, offers also possibilities of interaction. With these markers, a simple tool for controlling the movement of the robot is designed.

Mapping a confined area using a mobile robot
Dolák, Šimon ; Nevoral, Tomáš (referee) ; Holoubek, Tomáš (advisor)
This thesis focuses on the setup of the TurtleBot3 Burger robot in the ROS (Robot Operating System) environment and the development of assigned laboratory tasks. One of the tasks involves navigating the robot in a closed unknown environment, utilizing sensors and algorithms for mapping and localization. The second task involves reading QR codes. Both programs are developed in the simulation environment Gazebo and applicable to a real robot. The thesis also includes a brief review of mobile robots and the Robot Operating System.

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.

Anomalies detection in time-series data for the internal diagnostics of autonomous mobile robot
Věchet, Stanislav ; Krejsa, Jiří ; Chen, K.S.
Autonomous mobile robots are complex mechatronic machines which consists of numerous hardware and software modules working asynchronously to achieve desired behaviour. As there are many frameworks which helps to overcome the flat learning curve the problem of internal diagnostics arises. While users and developers are able to focus only on solving the high level problem algorithm or methods the internal states of the system is hidden. This helps to separate the users from solving hardware issues, which is helping until everything works properly. We present an algorithm which is able to detect anomalies in time based behaviour of the robot to improve the users confidence that the internal robot framework works correctly and as desired. The algorithm is based on probabilistic patterns detection based on Bayesian probabilistic theory.

Turtlebot in ROS framework
Bartoš, Pavel ; Šoustek, Petr (referee) ; Hůlka, Tomáš (advisor)
The aim of this work is to create a model of Turtlebot and to test it in the Gazebo environment. The paper presents a series of algorithms that simulate the movement of the robot and its ways of orientation in a selected space. The created solution provides the robot with the ability to create a collision-free course based on the sensor data. The benefit of this work is to introduce the ROS framework and bring an undestandment of its features.
