Localization with Optical Markers in Mobile Robotics
Vítek, Filip ; Jílek, Tomáš (referee) ; Gábrlík, Petr (advisor)
The problems of mobile robotics includes, for example, method of navigation or positioning of mobile robot. This thesis deals with one of the many posibilities, which is the use of optical markers. The first part of this thesis is recherche about implementation of optical markers and the result is slection of the ArUco library. Under the open source license is available program library for the detection of these markers, which was used for measurement. The second part of thesis is concerning with making and adjusting program equipment and preparation or construction others necessary utilities. Then the mesurement was made, which was mainly focused on accuracy and success of detection. The results may be viewed in graphs and summarized in coclusion.

Detection and classification of objects of interest for watering mobile robot using image processing
Sladký, Jiří ; Šnajder, Jan (referee) ; Krejsa, Jiří (advisor)
This thesis deals with image processing on autonomous watering mobile robot using embedded computer NVIDIA Jetson Nano. A method for object detection, YOLOv5, was chosen, which served for detection of flowers and flower pots. Using a method for monocular depth estimation, MiDaS, relative depth map was predicted. An algorithm was created, which converted this map to metric depth map using data from LiDAR. Thanks to that, distance of the detected flowers could be estimated. The created tools were implemented in ROS framework and tested on real data form indoor environment.

ROS framework utilization for autonomous mobile robot control system
Vávra, Patrik ; Krejsa, Jiří (referee) ; Appel, Martin (advisor)
Tato práce se zabývá vytvořením lokalizačního a navigačního systému mobilního robota pro vnitřní prostředí pomocí frameworku ROS. Stručně je zde představen projekt, v rámci kterého diplomová práce vznikla, a jeho cíle. V rešeršní části je v krátkosti popsán ROS framework, simulační prostředí Gazebo a senzory, kterými robot disponuje. Následuje vytvoření modelu robota a simulačního prostředí, v němž jsou vyzkoušeny lokalizační, navigační a další rutiny. V experimentální části je provedeno testování senzorů a popsáno využití jejich výstupů. Následně jsou upraveny a otestovány algoritmy ze simulace na reálném robotovi. V závěru jsou popsány vytvořené vzdělávací minihry. Hlavním výstupem této práce je funkční stavový automat, který umožňuje manuální ovládání, zadávání cílů pro navigaci a v případě potřeby zajistí autonomní nabití robota.

Calibration of Robotic Workspace
Uhlíř, Jan ; Veľas, Martin (referee) ; Kapinus, Michal (advisor)
This work is concerned by the issue of calibrating a robotic workplace, including the localization of a calibration object for the purpose of calibrating a 2D or 3D camera, a robotic arm and a scene of robotic workplace. At first, the problems related to the calibration of the aforementioned elements were studied. Further, an analysis of suitable methods for performing these calibrations was performed. The result of this work is application of ROS robotic system providing methods for three different types of calibration programs, whose functionality is experimentally verified at the end of this work.

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.
