Universal drive unit
Sehnálek, Lubomír ; Frýza, Tomáš (referee) ; Fedra, Zbyněk (advisor)
This document deal with design of universal driving unit. For the final solution is required driving unit which will be controled with help of sensory unit placed on the chassis of driving unit. In theoretical part of this labour are examined possibilities of a power, electric motor operation by PWM, kind of chassis and odometry which could be taken into account. From this section is finally chosen concrete configuration which is then described in chapter concerned oneself with driving unit design. Construction of equipment is shown in next chapter where final configuration of equipment is described.

Probabilistic Localization of Mobile Robot
Kopečný, Tomáš ; Luža, Radim (referee) ; Rozman, Jaroslav (advisor)
Motion control, navigation and sense of orientation of a mobile robot are tied to development of every mobile robot. This work concerns mainly about robot localization in the sense of orientation in space. Nevertheless, nor other aspects of mobile robotics are being omitted. Therefore, the goal of this work is to get familiar with Monte Carlo localization algorithm and apply this algorithm on a real robot.

Robot for Robotour 2010
Kubát, David ; Zbořil, František (referee) ; Rozman, Jaroslav (advisor)
The objective of this master's thesis was to get acquainted with an autonomous outdoor robot competition - The Robotour and further to study the capabilities and information about a robot designed on the DITS FIT Brno VUT. Next part of the project was to study various planning and localization algorithms and to make a proposal of a functional solution, allowing the robot to participate in the competition. To be specific, the goal of this work was to use the acquired knowledge for implementation of an antonomous software so the robot can start in the year 2010 race. The solution also included several related mechanical modifications. The final solution fulfills all the competiton rules and is capable of taking part in this year's plant.

Mobile Robot Navigation
Goldmann, Tomáš ; Luža, Radim (referee) ; Orság, Filip (advisor)
When we look at the eld of robotics we nd that exist a lot of types of robots. Some of tham use location navigation and global navigation for their work. This work aims to map options of location navigation and description of basic technique which used. Especially, we will deal with algorithms which work with optical sensors, for example camera, stereocamera or laser which scan medium. Practise section this work is focused on the proposal and implementacion algorithm which working with local navigation for robot's return to the starting position. All this work is connecting with tracked robot which formed in the framework one of project realization at Faculty of information technology.

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.

Wheelchair
Kutnar, Pavel ; Burian, František (referee) ; Šembera, Jaroslav (advisor)
Thesis describes the design, development and testing of new control unit of the wheelchair. Odometry, complete control of the wheelchair and a simple communication protocol provides to superior sytem an opportunity of autonomous control. The document contains a description of the wheelchair modifications, odometry theory including its application and a description of the unit itself. The basis of the electronic part is an ATmega16 microcontroller. Tests reveal problems of odometry and suggest possible improvements.

Application of SLAM algorithms for 4WS vehicle
Najman, Jan ; Krejsa, Jiří (referee) ; Grepl, Robert (advisor)
This paper deals with the application of SLAM algorithms on experimental four wheel vehicle Car4. The first part shows the basic functioning of SLAM including a description of the extended Kalman filter, which is one of its main components. Then there is a brief list of software tools available to solve this problem in the environment of MATLAB and an overview of sensors used in this work. The second part presents methodology and results of the testing of individual sensors and their combinations to calculate odometry and scan the surrounding space. It also shows the process of applying SLAM algorithms on Car4 vehicle using the selected sensors and the results of testing of the entire system in practice.
