Electronic Subsystem of a Small Mobile Robot
Podolan, Luděk ; Jílek, Tomáš (referee) ; Žalud, Luděk (advisor)
The topic of this bachelor thesis is design and construction of a mobile robot with wheeled differential platform. The main goal was to design, implement and test an electronic sub-system for a small mobile robot. Each chapter firstly deals with theoretical aspects of relevant topics and after that describe the process of construction. The thesis shows various ways of construction of the robot with the process of selection of the optimal one. The main controlling part of the robot is the AVR microcontroller placed on the EvB4.3 development board. A simple menu was created on an LCD display for communication between the user and the robot. Battery management is controlled by an analogue to digital converter. The last two chapters focus on encoders and communication between the robot and a proximity sensor. Pictures of the robot are enclosed at the end of the thesis.

Mobile robot path planning
Klobušníková, Zuzana ; Šoustek, Petr (referee) ; Dvořák, Jiří (advisor)
This master thesis deals with the planning of the robot's path using selected graph algorithms of artificial intelligence. The theoretical part describes the basic methods of planning a robot's path. It is related to the graph algorithm more closely. The practical part deals with implementation of selected graph algorithms, creation of simulation environment in Python, description and evaluation of experiments.

Usability of compass in indoor mobile robot navigation
Pilch, Petr ; Ripel, Tomáš (referee) ; Krejsa, Jiří (advisor)
This work is focused on usability of compass HMC6343 for controlling the mobile robot in an indoor environment. The first part shows the history of compass and describes the principle of operation of some types of compasses including anisotropic magnetoresistive sensor. HMC6343 compass used for the measurements in real environment is based on this principle. The measurement is evaluated and the usability of data gathered this way is discussed the second part of the thesis.

Control of multiple-steer vehicle
Krsek, Jiří ; Kopečný, Lukáš (referee) ; Šolc, František (advisor)
The subject matter of the bachelor thesis is a creation of functional model of mobile robot equipped with multiple-steer chassis. The robot will have its own control unit consisting of 32-bit processor and wireless communicatin unit, which enables the contact with superset system. The superset system serves as visualization interface robot - operator and enables to enter the data for requested movement of robot. The calculation of movement of each actuator is ensured by control unit of robot.

Design of single-wheel mobile robot
Lochman, Vít ; Knoflíček, Radek (referee) ; Kočiš, Petr (advisor)
The diploma thesis deals with the design of a single-wheel mobile robot, which is able to jump and collect samples weighing 2 Kg. The first part is devoted to the review of single-wheel robots. A brief analysis of single-wheel motion and a brief overview of jumping mechanism follow up. The second part describes problem analysis and five design variants. Using the multicriteria analysis, the variants were evaluated, and the optimal variant was chosen. The third partm is dedicated to the dynamic calculations and the mechanical design of the robot itself. The last part is devoted to economic evaluation and discussion with possible continuation in developing. The complete drawing documentation of the robot is included in this work.

Validation of human body biological parameters for robotic visual telepresence
Cheparukhina, Anna ; Kopečný, Lukáš (referee) ; Žalud, Luděk (advisor)
This work presents a research in the field of robotic visual telepresence. At the beginning explains the principle of teleprezence and it makes classification of robots according to their properties and concepts. Furthermore, there is a review of modern existing robots. The following chapter discusses the human visual system, the basic parameters and functions including parameters of head movements. Subsequently have been selected critical parameters for visual telepresence. At the conclusion of the theoretical part were designed some experiments to validation of human body biological parameters. In the practical part was conducted measuring the extent and speed of head movements, eye distinction depending on the lighting and measurement of visual field man. Also, a series of experiments was performed for practical technical embodiment of the telepresence system rescue robot for class Orpheus.

Mobile robot path planning by means of ant algorithms
Sedlák, Václav ; Šoustek, Petr (referee) ; Dvořák, Jiří (advisor)
This thesis deals with robot path planning by means of ant colony optimization algorithms. The theoretical part of this thesis introduces basics of path planning problematics. The theoretical part either deals with ant algorithms as optimization and path planning tools. The practical part deals with design and implementation of path planning by means of ant algorithms in Java language.
