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.

Teleoperation Interface for a Semi-Autonomous Vehicle Using Virtual Reality
Revický, Peter ; Kapinus, Michal (referee) ; Rozman, Jaroslav (advisor)
The goal of this work is to come up with user interface in virtual reality for vehicle robot teleoperation that is equipped with cameras, Velodyne laser distance meter and localization system. The user interface is designed with generally accepted methods for creation of user interfaces in virtual reality. This work also deals with the problem of sickness from VR. The user interface is implemented in Unity3D game engine. The HTC Vive Pro virtual reality kit was used during implementation and testing.

Operational safety of mobile robots in indoor environment
Vojta, Jakub ; Věchet, Stanislav (referee) ; Krejsa, Jiří (advisor)
During cooperation with the Bender Robotics company a need for operational safety assessment of an autonomous mobile robot (AMR) emerged. Operational safety evaluation is a step towards mass production of the studied robot. Market entry of a product requires a string of various actions and safety assessment is one of them. For risk identification and severity rating were used legal requirements, best practice given by standards, FMEA method, experiment and RIPRAN method. Threats, possible scenarios and risks analysis is systematically discussed through all areas of operation of the robot, from design and construction to control software. All the steps are described in logical order. Starting with information research, going on with series of analysis and ending with suggestions for increased operational safety of autonomous mobile robots.

Graphical Environment for Robot Simulation
Malina, Michal ; Kočí, Radek (referee) ; Zbořil, František (advisor)
This thesis deals with robot modelling and simulation of the robot behavior. At first we discuss a benefit of this kind of simulation. Next we describe the general scheme of robot. After that we select the environment where robot will be simulated in. There is a conception of this robot and explanation of the implementation in chosen environment. We continue with design and realization of the communication interface of this robot. The result of this procedure is robot with independent movement able to response to the obstructions and avoid them. Robot is able to create a map of the environment and use this map to find out the optimal way to the scheduled goal using the A* algorithm and achieve this goal. There is a possibility to use more robots in the scene. These communicate and the nearest one is able to get the goal.

Indoor Robot - Control Neural Network
Křepelka, Pavel ; Kopečný, Lukáš (referee) ; Žalud, Luděk (advisor)
In this document, I describe possibilities of mobile robot navigation. This problems are solving many different ways, but there isn’t satisfactorily result to this day. You find there describe of deterministic algorithms, this algorithms can be used for simply actions like obstacle avoiding or travel in corridor. For global navigation this algorithms fails. In next part of document is theory of artificial neural nets (perceptron, multi layer neural nets, self organization map) and using them in mobile robots. Own navigation algorithms was tested on constructed mobile robot or simulated in SW described in chapter 6. Design own control algorithms is based on neural net (Kohonen net). Designed algorithms can be used for one-point navigation or complex global navigation. In document, there is comparing of various ways to navigation, their advantages and disadvantages. Goal of this document is find effective algorithm for navigation and artificial intelligence appears to be the right solution.

Navigation of mobile robots
Rozman, Jaroslav ; Matoušek,, Václav (referee) ; Šolc, František (referee) ; Zbořil, František (advisor)
Mobile robotics has been very discussed and wide spread topic recently. This due to the development in the computer technology that allows us to create better and more sophisticated robots. The goal of this effort is to create robots that will be able to autonomously move in the chosen environment. To achieve this goal, it is necessary for the robot to create the map of its environment, where the motion planning will occur. Nowadays, the probabilistic algorithms based on the SLAM algorithm are considered standard in the mapping in these times. This Phd. thesis deals with the proposal of the motion planning of the robot with stereocamera placed on the pan-and-tilt unit. The motion planning is designed with regard to the use of algorithms, which will look for the significant features in the pair of the images. With the use of the triangulation the map, or a model will be created. The benefits of this work can be divided into three parts. In the first one the way of marking the free area, where the robot will plan its motion, is described. The second part describes the motion planning of the robot in this free area. It takes into account the properties of the SLAM algorithm and it tries to plan the exploration in order to create the most precise map. The motion of the pan-and-tilt unit is described in the third part. It takes advantage of the fact that the robot can observe places that are in the different directions than the robot moves. This allows us to observe much bigger space without losing the information about the precision of the movements.

Design of a Mobile Robotic Platform
Kolář, Vít ; Drahanský, Martin (referee) ; Orság, Filip (advisor)
This thesis focuses on a design of a mobile robotic platform for an autonomous grass-reaping machine controlled by wireless connected computer. There is some information about the creation and objects of this project in the beginning and than the reader is made familiar with two autonoumous grass-reaping machines that are already on the market. The main chapter describes all the robots subsystems such as senzory, motoric and control subsystem. The issue of power supply and navigation is also mentioned. All these parts are beeing described both theoretically and from the point of autonomous grass-reaping machine as well.

Visualisation of Path-Finding for Robot
Kvasnica, Miroslav ; Orság, Filip (referee) ; Rozman, Jaroslav (advisor)
This thesis deals with sampling-based algorithms for robot path planning. Theoretical principles of probabilistic path finding and its implementation details are discussed here. The second part focuses on individual algorithms - PRM, EST, RRT and SRT and its modifications. Java applets for visualisation of algorithms and web pages related with sampling-based algorithms are included on the CD.
