Simulation of Autonomous Mobile Robots
Janoušek, Radim ; Burian, František (referee) ; Lázna, Tomáš (advisor)
The goal of this work is to implement robotic algorithms for autonomous tasks. The thesis starts with an introduction to the ROS 2 framework, where the basic features of this framework are introduced. This is followed by a comparison of the most popular robotic simulators, including a more detailed description of the Gazebo simulator and the lesser known Webots simulator. The next chapter focuses on the reasons for choosing the Webots simulator for creating the simulated world and describes the process of creating the interior based on the template. The penultimate chapter discusses the creation of robotic platforms in the Webots simulator and the sensors used, including the simulated lidar. In this simulation, the lidar is created with a mock-up of the real device. In the last chapter, the drivers for controlling the robotic platforms are implemented and a package for ROS 2 is created.

Virtual launch of the robotic welding and gluing line using Tecnomatix - Process Simulate
Tomeček, Radim ; Juříček, Martin (referee) ; Simeonov, Simeon (advisor)
This thesis deals with the design and creation of a virtual twin of a robotic cell intended to simulate and create a virtual launch of this cell. The goal was to design the layout of the robotic cell and subsequently create a full virtual run of an automated robotic workstation designed for spot welding, MIG welding and bonding processes. The initial research section deals with the individual technologies to be simulated. Subsequently, three designs for the layout of the robotic workstation are developed in this thesis. After evaluating and selecting the design, a virtual twin of the robotic cell is created using Process Simulate and then all the processes are simulated resulting in the virtual launch of the cell.

Virtual commissioning of a robotic welding workplace
Provazník, Adam ; Pavlík, Jan (referee) ; Vetiška, Jan (advisor)
This bachelor thesis is focused on the design of a robotic welding cell, a clamping fixture for a given component and subsequent virtual commissioning of the workplace. In the theoretical part is examined a current knowledge of industrial automation and robotics, as well as MIG welding method. An analysis of the clamping fixture and workplace, and a summary of the main aspects for their design are carried out furthermore. In the practical part are designed 3D models based on the previous analysis. A control program is created for these models and the workplace is virtually commissioned.

Badatelsky orientovaná výuka robotiky
KLOFÁČ, Patrik
Newly conceived informatics focused on the development of pupils' computational thinking is constantly looking for new topics and new modern teaching methods to support active pupils. In the school environment, robotics appears to be a suitable educational topic for developing IT skills, competences, and computational thinking. Working with robots will not be beneficial if the teaching methods are used with passive pupils, and are merely transmissive, and instructional. For these reasons, it is necessary to look for new methods, and one of the possibilities is inquiry-based learning. In general, the subject of inquiry-based learning in informatics and also in robotics is practically unexplored, and it is not yet clear what to imagine under the heading of such teaching. Therefore, the research is focused on teaching the basics of robotics with inquiry-based learning tasks. The goal of the research was to create inquiry-based learning tasks for robotics lessons, and to find out whether inquiry-based robotics learning contributes to the development of computational thinking of second stage primary school (or middle school) students in these three components of algorithmization, abstraction, and evaluation. The work is based on qualitative research, using the action research method. Data collection was ensured by interviews with teachers, observation, and filming of students at work, along with student questionnaires. The results of the research provided an interesting and important insight into the structure of the creation of robotics research tasks, as well as the starting points for how to improve such tasks, and even what aspects to pay attention to in teaching. The findings can contribute to the development of informatics teaching.

Open interactive robotics platform for home use
STROPEK, Martin
The thesis focuses on the design and implementation of a functional mobile robot, which can be controlled through an interactive web application. The robot is capable of transmitting video and two-way audio, enabling its use in areas where remote monitoring is necessary (e.g. monitoring pets at home). The project is designed as an open-source platform with an emphasis on low cost and easy expansion of additional functionalities.

The Use of Digital Technologies in Seniors' Leisure Time
ŠACHOVÁ, Viktorie
This bachelor thesis describes how digitization is reflected in seniors' leisure activities and how it has changed in connection with the Covid Sars 19 pandemic. It is a theoretical work dealing with aging and old age as well as the changes and needs associated with this natural process. It also describes free time and leisure activities of seniors, and in the last part it focuses on digital technologies in free time and during the pandemic, specifically robots as social companions, and the phenomenon of virtual reality.

Robotizace v zemědělství - vizualizace dojicích stání obsluhovaných robotickou rukou
OTARGAZIYEV, Al-Farabi
The diploma thesis deals with the visualization of milking parlors operated by a robotic arm. The work is divided into two imaginary parts. The first part is a literary search. The basic principles used in industrial robotics and twenty case studies will be presented, which show advanced applications of robotics in various areas of agriculture and forestry. The second part deals with the creation of the model in SolidWorks and Autodesk Inventor. From the creation of individual parts of milking parlors to the assembly of these parts into an assembly. The result of this work is the visualization of milking parlors operated by a robotic arm.

Selected algorithms for detecting objects in the image and their use in guilding the robotic arm
ŠTINDLOVÁ, Lucie
This research work is focused on the detection of searched places in the image using selected algorithms. The work shows how closely physics is connected with informatics. In addition to the connection of these two areas, the work deals with the explanation of issues related to the fields. First of all, the algorithm is defned as such, as it is one of the key concepts in this work. Furthermore, the work characterizes the image and working with it not only from a cybernetic point of view, but also from a physical point of view. In this case, physical areas examining and describing electromagnetic radiation are expanded to better understand the image. Given that one of the final algorithms is practiced on the image from the thermal camera, the principle of the thermal camera function is generally explained in the work. Attention is also paid to neural networks (artificial intelligence) and the robotic arm. Several areas are mentioned in which this physical-cybernetic system is used. The practical part deals with the Python programming language, in which the basic algorithms are used, which can be used to detect an object in the image. Based on these and similar algorithms, which I would like to elaborate in more depth in the diploma thesis, the robotic arm will be guided.
