Construction and application of mobile robots suitable for non-industrial (non-production) use
Kocanda, Jakub ; Pavlík, Jan (referee) ; Knoflíček, Radek (advisor)
This bachelor thesis deals with mobile robots, their construction, applications in many non-manufacturing spheres. The literature search summarizes the principles of construction of these robots based on their possible application in a wide range of work environments. The research also includes an analysis of the key factors that affect their functionality and efficiency in assigned tasks and situations. In the next part are presented advances and potential directions for innovation in this area by using examples from practice. The summary of the work is to evaluate the key aspects and suggest further possible procedures in the development of these intelligent machines, in order to achieve a comprehensive understanding of this diverse subject.

Tichý, Dominik ; Sedlařík, Marek (referee) ; Vyroubal, Petr (advisor)
This work deals with the issue of IoT and the smart devices used in it. The work is further devoted to Robots, with a great emphasis on mobile robots. It discusses the types of chassis and the types of guidance in space using both classical and heuristic methods. The work also discusses the methodology of the design of electrical devices in practice. The design of the intelligent mower and its individual blocks is described in the next part. Following that, it moves on to the implementation itself, where the individual steps of implementation are described. The last part is dedicated to programming and testing individual mower functions.

Using hybrid maps in mobile robot localization and mapping
Fajgel, Oscar ; Králík, Jan (referee) ; Krejsa, Jiří (advisor)
This bachelor's thesis deals with analysis of current approaches to mapping used in mobile robotics and explores a hybrid mapping approach that could be used in mobile robot navigation and localization in multi-level indoor environments of buildings. Multiple methods are examined and a suitable approach is tested using ROS framework simulations. A real life test on a real robot is also concluded to test the usability of this approach.

Control System of Small Mobile Robot
Rysnar, Jiří ; Florián, Tomáš (referee) ; Žalud, Luděk (advisor)
This master’s thesis elaborates on the control of a wheeled mobile robot and its sensor system. The sensors provide information about distances of obstacles in its surroundings and orientation in area. The communication is realized by radiomodems, commands and data are sent by serial link between microncontroller and the PC.

Multispectral Map Building in Mobile Robotics
Burian, František ; Mazal,, Jan (referee) ; Zemčík, Pavel (referee) ; Žalud, Luděk (advisor)
The dissertation deals with utilisation of multispectral optical measurement for data fusion that may be used for visual telepresence and indoor/outdoor mapping by heterogeneous mobile robotic system. Optical proximity sensors, thermal imagers, and tricolour cameras are used for the fusion. The described algorithms are optimised to work in real-time and implemented on CASSANDRA robotic system made by our robotic research group.

Localisation of Mobile Robot in the Environment
Urban, Daniel ; Sochor, Jakub (referee) ; Veľas, Martin (advisor)
This diploma thesis deals with the problem of mobile robot localisation in the environment based on current 2D and 3D sensor data and previous records. Work is focused on detecting previously visited places by robot. The implemented system is suitable for loop detection, using the Gestalt 3D descriptors. The output of the system provides corresponding positions on which the robot was already located. The functionality of the system has been tested and evaluated on LiDAR data.

Advanced Navigation in Heterogeneous Multi-robot Systems in Outdoor Environment
Jílek, Tomáš ; Duchoň,, František (referee) ; Mazal, Jan (referee) ; Žalud, Luděk (advisor)
The doctoral thesis discusses current options for the navigation of unmanned ground vehicles with a focus on achieving high absolute compliance of the required motion trajectory and the obtained one. The current possibilities of key self-localization methods, such as global satellite navigation systems, inertial navigation systems, and odometry, are analyzed. The description of the navigation method, which allows achieving a centimeter-level accuracy of the required trajectory tracking with the above mentioned self-localization methods, forms the core of the thesis. The new navigation method was designed with regard to its very simple parameterization, respecting the limitations of the used robot drive configuration. Thus, after an appropriate parametrization of the navigation method, it can be applied to any drive configuration. The concept of the navigation method allows integrating and using more self-localization systems and external navigation methods simultaneously. This increases the overall robustness of the whole process of the mobile robot navigation. The thesis also deals with the solution of cooperative convoying heterogeneous mobile robots. The proposed algorithms were validated under real outdoor conditions in three different experiments.
