Using "Ozobot" in the kindergarten
Bochňák, Jan ; Černochová, Miroslava (advisor) ; Tocháček, Daniel (referee)
The diploma thesis examines options of using the ozobot robotic toy for education in kindergarten. The theoretical part is based on introduction of key concepts and review of existing knowledge about digital education with aims on early childhood education and care. In addition to the legislative framework and expert findings on digital technologies in preschool age, the risks associated with their use are also taken into account. Furthermore, the theoretical part includes findings about educational robotics and a description of the basic parameters of the ozobot toy, which is the focus of the research. The possibilities of using an ozobot in kindergarten are examined in the form of a case study that focuses on two levels of this issue, firstly on the features and functions of the ozobot, and secondly on how children perceive the ozobot and how they approach it with the aim of identifying possible obstacles, that may arise in kindergartens when working with the ozobot, offer the created thematic blocks for use and provide useful methodological guidelines and recommendations for them. The case study was carried out in one Prague kindergarten in two time-separated cycles, each time with a different group of six children aged 5-6 years from a different class. Ten thematic blocks with an ozobot were...

Using minirobot Ozobot with tablet for computational thinking development
ŠAFÁŘOVÁ, Denisa
This thesis is devoted to teaching algorithmization at primary school with the help of Minirobot Ozobot. The thesis deals with the creating a set of excercises for Ozobot on a tablet with focus on the development of algorithmization. The excercises are intended for a tablet or a computer with a tilting monitor. Some of the excercises can also be used on paper. The introductory part deals with the goals and methods of work including difficulties and problems in creating excercises. The theoretical part deals with robotics in computer science lessons, including programming, algorithms and computational thinking. This section contains a description of the Ozobot. It also contains the advantages and disadvantages of excercises for Ozobot on a tablet and research of available applications for the creation of excercises pads for Ozobot. Last but not least, there is a brief guide to the ArtFlow application. The practical part consists of a set of excercises which are divided into five chapters. They are divided according to what they deal with. Each excercise contains an assignment, preview, goal and methodological notes. The diploma thesis contains an appendix with worksheets which contain moreover the solution and topic.

Visual tracking of multiple robots
Lechovský, Adam ; Barták, Roman (advisor) ; Obdržálek, David (referee)
The aim of this thesis is to create a program which detects a grid on a paper in a fixed webcam image, converts the grid into a graph and then tracks a group of Ozobots as they traverse the grid. Earlier works with Ozobots used them to investigate Multi-Agent Pathfinding. This work is the first in exploring their detection in image data. To achieve that, I am using the OpenCV library and the Java programming language. By training my own cascade for use in a Cascade Classifier from the objdetect OpenCV module, I was able to achieve a good rate of Ozobot detection in real time. The grid detection works by detecting lines on the color transitions in the image and their subsequent grouping into lines in the grid.

Engagement of Ozobots in teaching algorithmization and computer science thinking
Yaghobová, Anna ; Forstová, Lenka (advisor) ; Töpfer, Pavel (referee)
Presently, there is a significant tendency of using educational robotics in Computer Science classes. The main purpose of my thesis is a.n introduction of Ozobot as a. tool for education. Va.rious excercises and methodical materials are also included. \Ve are not dealing with a full collection of excercises rather with samples concerning individual problems connected with algorithm educat.ion. Overally, t.here is twelve examples. Six oť them are ťocnsed on programming Ozobot with use oť colorťul OzoCodes on paper. The remaining six examples are ťocused on programming Chobot using special code editor OzoDlockly. l'vientioned excercises are int.eded for upper grades of Element.ary school and :diddlc school respectivcly.
