Minidarpa robot - software design
Kopecký, Martin ; Žalud, Luděk (referee) ; Kopečný, Lukáš (advisor)
This master‘s thesis deals with theme of autonomous mobile robots. In sequence of the bachelor’s thesis its goal is to design a control system of the outdoor mobile robot for Minidarpa type competition. It could be practically used for an autonomous transportation of material. In design of the control system the attention is aimed at planning algorithms which are divided into the local and the global parts. Most of the work is paid to a global planning algorithm, which plans, in help with graph algorithms, points needed to travel to achieve the goal. The global map is defined in RNDF file which must be preprocessed for needs of planning. There are designed classes in C++ language for communication with subsystems too. The control system further contains graphical interface for operation of the robot and a remote control through a wireless gamepad.

Minidarpa robot - senzoric subsystem
Sedlák, Luboš ; Žalud, Luděk (referee) ; Kopečný, Lukáš (advisor)
This master’s thesis describes a sensorial subsystem of a mobile robot. The thesis mentions the structure and a basis of the satellite navigation. There are also described each systems and visualization techniques as e. g. WGS 84, including also other systems for specification of more accurate position on the Earth (EGNOS, WAAS and others). This thesis describes closely also a differential GPS and the corrections. For the purposes of the thesis there has been assembled GPS software for a fundamental and a remote station. There have been chosen and used modules for receiving a GPS signal and wireless modules for their communication. There are also used outcomes from the project of the Open Street Map in the thesis. Results of this project are described in details, decoded, adjusted and converted into RNDF file. At the end of this thesis there has been composed a function of the program for portable camera which works on principle time of flight. This portable camera is dedicated to look for immediate barrier and also for 3D space view in front of the robot. This thesis also including the process how the power source has been built up for this portable scanner.

Minidarpa robot - electronic layout design
Groulík, Tomáš ; Burian, František (referee) ; Kopečný, Lukáš (advisor)
Bachelor`s thesis is bent on problems mobile robotics. In forepart is genarally circumscribed architecture AVR and individual used microprocessors. Next part is intend for distance evaluation by the help of ultrasonic sensores and concrete description of used modulus. Last part is specialized in motor control and regulation of DC motor. There are described possibilities of motor control by the help of PWM and used draft of motor control and projecting of regulator.

Modelling and control of wheeled mobile robots
Jonszta, David ; Šembera, Jaroslav (referee) ; Šolc, František (advisor)
The thesis deals with modelling and control of wheeled mobile robots. The thesis introduces the mathematical models of diferentially driven mobile robot, robot with Ackerman steering and a skid steered robot. The thesis describes open-loop and feedback control. Feedback control is divided into point-to-point control, path following and trajectory tracking.

Control Theory of robotic snakes with more than three links
Tejkal, Martin ; Návrat, Aleš (referee) ; Hrdina, Jaroslav (advisor)
The subject of this Bachelor's thesis is control theory of mechanism that simulates snake's movement. From a viewpoint of control theory the robot is classified as nonholonomic system, controllability of which is determined by vector fields. Based on nonholomic constrain a set of input vector fields is obtained from a system of nonholonomic equations. The other vector fields that are necessary for controllability of the system are derived from the set of input vector fields by application of Lie bracket operation on two input fields. This set of vector fields is further analysed in particular points of the configuration space. Finally we discuss changes that need to be done in order to describe a mechanism created by adding one, or more new links.

Construction of a mobile robot for monitoring ambient temperatures
Ferenčák, Libor ; Jančík, Stanislav (referee) ; Zuth, Daniel (advisor)
The aim of this bachelor´s thesis is to design and to construct a mobile robot that is able to monitor ambient temperature and to watch if there is no danger caused by high temperature. The work also deals with the theoretical description of elements that could be used. The whole system is based on ATmega microcontroller 128, which is described here, including the support plate. The individual components that are used in a robot are also described here, and programs controlling the individual components are attached. An algorithm is designed and described to a detail which could control the robot and monitor the temperature.
