Path Planning for Robot Formations
Hornáček, Zdenko ; Uhlíř, Václav (referee) ; Rozman, Jaroslav (advisor)
Robotics has been experiencing great development in recent years. This development is due to constant technical progress and the effort to develop increasingly robust robots and to further develop co-operating groups of robots. These co-operating groups (robot formations) have many areas of use ranging from environmental mapping to search and rescue missions. This bachelor thesis deals with the design of the path planning algorithm for robot formations. It uses the already existing planning algorithm for single robot - the Dijkstra algorithm. Based on the path computed by this algorithm, the proposed algorithm will calculate the path for each robot so as to maintain the shape of the formation during its move to the goal.

Strategic Game on Interactive Table
Jiruška, Adam ; Najman, Pavel (referee) ; Kapinus, Michal (advisor)
The aim of this work is to implement strategic board game on an interactive table. This table is ARTable, a platform which is developed at the Faculty of Information Technology, BUT. Here the principle of combination of the projected user interface and the touch layer on the table is used. The created app allows to play slightly modified version of the wellknown game Settlers of Catan for up to four players, including the ability to edit and create new maps.

Robotic Vehicle Using RC Components
Deingruber, Ondřej ; Beran, Vítězslav (referee) ; Zemčík, Pavel (advisor)
This thesis covers the topic of controlling RC servos and constructions of robotic vehicles. The goal is to propose a model of robotic vehicle with RC components and other off the shelf components, 3D printing and demonstrate its capabilities. In the thesis, a mobile robot platform was proposed. It uses a single-board computer together with readily available parts and does not require complicated assembly. An optimization algorithm was used for the design of rack and pinion steering. The result of the thesis is the implementation of a robotic vehicle.

Sensor system design for mobile robot based on ROS framework
Tomáš, Petr ; Mašek, Petr (referee) ; Věchet, Stanislav (advisor)
The essence of this master thesis is design and implementation of sensor system based on robotic framework which is called ROS (Robot Operating System). The main task is to perform detailed analysis and test of capabilities of the framework with final implementation on specific robot application (sensor system) with following evaluation of applicability of the system in mobile robotics. As parallel aim is to create detailed general and practical guide for beginners with ROS which they are also beginners in Linux based operating systems.

Tabletop Object Detection
Varga, Tomáš ; Zemčík, Pavel (referee) ; Španěl, Michal (advisor)
This work describes the issue of tabletop object detection in point cloud. Point cloud is recorded with Kinect sensor. Designed solution uses algorithm RANSAC for plane detection, algorithm Euclidean clustering for segmentation and ICP algorithm for object detection. Algorithm ICP is modified and mainly it can detect rotational symetric objects and objects without any transformation against it's models. The final package is build on platform ROS. The achieved results with own dataset are good despite of the limited functionality of the detector.

Web Tool for Playing and Anotation of BAG Files
Omacht, Martin ; Bambušek, Daniel (referee) ; Kapinus, Michal (advisor)
This work deals with the design and implementation of a web application for playback and annotation of multimedia data from files in BAG format. The created annotations are intended for training artificial intelligence in robotic systems. The resulting application is implemented with the help of React library for creating the user interface and framework Django for the server-side REST API. The entire application is containerized using Docker. This work describes the BAG format, analyzes modern libraries for creating web applications and introduces existing solutions for data annotation or playback of BAG files. Furthermore, the design of the application is presented and its implementation is described. A separate library rosbag_pyreader, which is used to read BAG files with random access, was created as part of this work. The resulting application allows user to display and annotate 2D and 3D data from multiple robotic sensors at the same time and then export the annotations in JSON format.

Dynamic Scene Model for Mobile Robot
Görig, Jan ; Štancl, Vít (referee) ; Španěl, Michal (advisor)
This master's thesis focuses on representation of geometric information about the surrounding environment for robotic systems. Instead of a common point-cloud based representation, an environment model that stores information about objects described by bounding boxes and planes is proposed. These objects can be obtained from trained object detectors, planar surface detectors, etc. processing data from sensors (e.g. RGB-D camera). The information about the objects (position, etc.) stored in the model is constantly changing according to data obtained from detectors. The environment model is implemented as a module for Robot Operating System. To illustrate and visualize features of the model, a demonstration application was also prepared.

QR code detection under ROS implemented on the GPU
Hurban, Milan ; Věchet, Stanislav (referee) ; Krejsa, Jiří (advisor)
Tato diplomová práce se zabývá vývojem a implementací algoritmu pro detekci QR kódů s integrací do platformy ROS a výpočty běžícími na grafické kartě. Z rešerše současně dostupných nástrojů a technik je vybrán vhodný postup a algoritmus je napsán jako modul v programovacím jazyce Python, který je snadno integrovatelný do ROS. Ke zprostředkování výpočtů na vícejádrovém hardware, jako jsou grafické karty či vícejádrové procesory, je využita knihovna OpenCL.
