Comparation of the 2D LIDAR SLAM methods in the simulation and in the real world
Cihlář, Miloš ; Jelínek, Aleš (referee) ; Ligocki, Adam (advisor)
This thesis deals with the design of a mobile robotic platform with the ability to build a map with an already existing 2D SLAM algorithm and a comparison of this algorithm in simulation and the real world. It uses three known algorithms i.e. Hector slam, Gmapping, and Karto slam. The part of this work deals with the creation of two wheels differential drive robot models in the Gazebo simulator and with an implementation proposal that is realized with the ROS framework. In thesis is implemented basic localization technique for mobile robots. Planning algorithms and a path controller are mentioned. In thesis is proposed own access to an autonomous exploration of building to build a map of the building. For evaluation of the SLAM algorithm is suggested slam quality criterion.
Vectorized Point Clouds for Mobile Robotics
Jelínek, Aleš ; Mazal, Jan (referee) ; Duchoň,, František (referee) ; Žalud, Luděk (advisor)
Disertační práce se zabývá zpracováním mračenen bodů z laserových skenerů pomocí vektorizace a následnému vyhledávání korespondencí mezi takto získanými aproximacemi pro potřeby současné sebelokalizace a mapování v mobilní robotice. První nová metoda je určena pro segmentaci a filtraci surových dat a realizuje obě operace najednou v jednom algoritmu. Pro vektorizaci je představen optimalizovaný algoritmus založený na úplné metodě nejmenších čtverců, který je v současnosti patrně nejrychlejší ve své třídě a blíží se tak eliminačním metodám, které ovšem produkují výrazně horší aproxi- mace. Inovativní analytické metody jsou představeny i pro účely vyjádření podobnosti mezi dvěma vektorizovanými skeny, pro jejich optimální sesazení a pro vyhledávání korespondencí mezi nimi. Všechny představené algoritmy jsou intezivně testovány a jejich vlastnosti ověřeny množstvím experimentů.
Terrain passability analysis using machine understanding of maps
Pařík, David ; Jelínek, Aleš (referee) ; Chromý, Adam (advisor)
The diploma thesis deals with creation of computer aplication that can be used for conversion of raster maps for orienteering into model. Aplication will use this model to calculate optimal track between two selected locations. The thesis describes the development of a module for speed analysis in different types of terrain and another module for detection of roads and impassable objects. Thesis builds on work of Ing. Pavol Kršák and describes new features that were implemented to simplify user's control.
Anti-collision safety system for mobile robots
Křivský, Josef ; Burian, František (referee) ; Jelínek, Aleš (advisor)
The bachelor thesis deals with the design of contactless anti-collision system for mobile robots. The design is concentrated on efficient obstacle detection, with the highest possible safety of operation, most effective sensor layout, but also sufficient modularity and scalability for use on different robot models.
Structured-light 3D scanner
Hadzima, Jaroslav ; Chromý, Adam (referee) ; Jelínek, Aleš (advisor)
3D scanner is a device capable of creating a model using analysis, most commonly from image data. 3D scanners could be divided into two major groups, contact and noncontact scanners. Aim of this study is to interpret problematics of 3D scanning with structured light. Specifically usage of Gray code patterns. There is step by step evaluation of individual hardware and software obstacles and possible errors, from calibration to final point cloud. In next section, there are included tests determining quality, precision and accuracy of scanning with given method. System is applicable to mobile robots and yet fully remotely controlled. The majority of enumerations is taking place in Raspberry Pi 3 model B, just visualization alone is done from computer.

Methods for Simultaneous Self-localization and Mapping for Depht Cameras
Ligocki, Adam ; Jelínek, Aleš (referee) ; Žalud, Luděk (advisor)
Tato diplomová práce se zabývá tvorbou fúze pozičních dat z existující realtimové im- plementace vizuálního SLAMu a kolové odometrie. Výsledkem spojení dat je potlačení nežádoucích chyb u každé ze zmíněných metod měření, díky čemuž je možné vytvořit přesnější 3D model zkoumaného prostředí. Práce nejprve uvádí teorií potřebnou pro zvládnutí problematiky 3D SLAMu. Dále popisuje vlastnosti použitého open source SLAM projektu a jeho jednotlivé softwarové úpravy. Následně popisuje principy spo- jení pozičních informací získaných vizuálními a odometrickými snímači, dále uvádí popis diferenciálního podvozku, který byl použit pro tvorbu kolové odometrie. Na závěr práce shrnuje výsledky dosažené datovou fúzí a srovnává je s původní přesností vizuálního SLAMu.
Algorithms for browsing 2D maze
Chvíla, Lukáš ; Jelínek, Aleš (referee) ; Žalud, Luděk (advisor)
This thesis describes an automatic path finding method in a 2D maze defined by bitmap evidence grids. The problem was solved in the programming language C# with the help of the straight line decomposition algorithm used for creating a network of potential routes. The algorithm assumes approximation of obstacles by vector polygons. The resulting path was found by the means of algorithm A*. The result is a path described by line segments. After some modifications, the path could be used for robot navigation.
