Mobile robot navigation by means of fuzzy logic
Janovec, Aleš ; Jančík, Stanislav (referee) ; Dvořák, Jiří (advisor)
In the introductory part of this thesis there is an analysis of methods, which are used for navigation of mobile robots. The main part of the thesis contains a proposal of control system of mobile robot. Robot control system is based on fuzzy modeling. To test the control, a system simulation environment is created in C #, in which experiments were performed.

Vehicle Navigation Systems
Mišinger, Lukáš ; Janda, Marcel (referee) ; Hájek, Vítězslav (advisor)
This bachelor thesis consider contemporary navigation systems or systems that will be at work very soon. This work includes main parting of satellite navigation systems and their functions and charakteristics, board units of navigation systems and their usage in vehicles. Next part is about another usage in transportation jointed sevices. Last part is about suggestion for laboratory practise with specialization on navigation systems for lessons of subject BAEB (Vehicle elektrotechnics).

Taxi-Dispatch Optimization Due to Effective Usage of Geolocation Services
Sekerka, Jan ; Martinovičová,, Dana (referee) ; Kříž, Jiří (advisor)
This diploma thesis deals with the operation of taxi-dispatch system and possibilities of its optimization by using geolocation services. The introductory part of diploma thesis contains theoretical basis used for an analysis of the current state and for design of an appropriate solution. The analysis of the current state deals with description of dispatch system functions within the selected company, finding weaknesses of the current system and also includes an analysis of market with systems designed for dispatch operation. Based on the analysis has been proceeded to design a custom solution consisting of a mobile application and a server part, which was then put into practice in the chosen company. Diploma thesis is finished by an evaluation of the proposal, which is based on the comparison of the situation before and after the introduction of the proposed solution.

Indoor Robot - Local Navigation
Matějka, Lukáš ; Šolc, František (referee) ; Žalud, Luděk (advisor)
This thesis deals with the problematic of design and realization of autonomous mobile robot, specifically with the subsystem for local navigation for a robot controlled by global navigation based on self-organizing neuron map, possible chassis design and control of these designs. Obstacle detection system is designed as well as optimum direction finding algorithm. Final section of this thesis concerns the possibilities of future improvements and development.

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.

Mobile robot design
Uherek, Vítězslav ; Neužil, Tomáš (referee) ; Krištůfková Dvorská, Jolana (advisor)
This work deals with issues of construction and sensors used in mobile robots. At the start of this work are examples of mobile robots for all environments are introduced. The primary aim is to design autonomous mobile robot that is able to navigate from a starting point to a goal point, both given by data from GPS coordinates and data from sensors. Part of this work is a design, realization and optimal layout of sensors on RC model E-maxx.

Guiding of Mobile Robot
Podivín, Ladislav ; Hrabec, Jakub (referee) ; Lebeda, Ondřej (advisor)
This bachelor’s thesis deals with design and implementation of control algorithms for GPS guided mobile robot Ryder. Especially two main abstract layers of mobile robot control are discussed - planning algorithm and algorithm providing steering control. The Ryder robot is equipped with several types of range sensors and based on Ackerman's steering. Its purpose is autonomous movement from start point to goal point without any collision with obstacles.

GPS Navigation for Outdoor Robot
Maceček, Ivo ; Kopečný, Lukáš (referee) ; Žalud, Luděk (advisor)
Differential GPS (DGPS) is system for getting position of an object. Describe principles DGPS, which is one of options for improvement GPS. It`s mentioning theory about several system design methods and detailed description of chosen solution. There are proposed some types of getting object bearing. These related topics are used in navigation software for outdoor robot.
