Gamma Radiation Measurement
Lázna, Tomáš ; Jílek, Tomáš (referee) ; Žalud, Luděk (advisor)
This thesis is focused on detection of ionizing radiation, especially gamma radiation. In its theoretical part the issue is presented and the most common detector types (gas filled, scintillation and semiconductor detectors) are analysed. In its practical part the parameters of the chosen sensor HDS-100GN are verified with a focus on its capability of dynamical measurement. The robot Orpheus-X3 equipped with the precise RTK-GNSS receiver was used in the realization of the experiment. The analysis of the measurement results furthermore covers conversion of geographical coordinates to distance, determination of latency, conversion of measured value to dose rate and comparison with theoretical assumptions were solved. Formation of an area radiation map is also concerned. Direction-sensitive detection of gamma radiation is also studied in this thesis.

3D Mapping of Outdoor Environment
Janalík, Radim ; Orság, Filip (referee) ; Herman, David (advisor)
This thesis deals with 3D map building of outdoor environment using laser rangefinders. Sensor measurements are transformed to the points and are aggregated to an internal model with respect to the current robot's position. From these points, a triangular mesh is created using Delaunay triangulation algorithm. The memory requirements for storing the internal model are reduced by mesh decimation algorithm. The presented method builds the map incrementally in real time. Several experiments have been conducted to verify the presented approach.

Electric drivers for robotics area
Matušík, David ; Huzlík, Rostislav (referee) ; Knoflíček, Radek (advisor)
This bachelor thesis deals with the problematic of electric drives in a robotics area. The first part focuses on the history of industrial and mobile robots. In the second part is made an evaluation of the current state in the field of electric drive units which are used for stationary and for mobile robots. Following chapter contains a research of suitable power energy supplies for direct current drives of mobile robots. The conclusion of this bachelor thesis is devoted to a critical evaluation and recommendations for constructors.

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.

Control System for Outdoor Mobile Robot
Skočdopole, Tomáš ; Burian, František (referee) ; Žalud, Luděk (advisor)
The aim of this thesis is the design and practical realization of control system based on operating system GNU/Linux for mobile robots operating outdoors. The task of the robot is automatically driving through waypoints in a previously unknown environment. First part contains a description of the environment for the implementation of software, introduces individual parts of the software and then describes communication with the robot peripherals. The second section describes the solution of control and navigation algorithms. At first shows a way to enter the path for independently moving, next an introduction to image processing from the camera and at last determining the direction of movement based on data obtained from the sensory subsystem.

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.

Autonomous mobile robot motion planning strategy design
Doseděl, Miroslav ; Králík, Jan (referee) ; Věchet, Stanislav (advisor)
This work is concerned with planning the movement of the robot in space and near plants. The main goal is to realize the movement of a robot designed for operation in indoor areas of buildings for watering indoor plants. In the first part of the thesis, existing algorithms for motion planning and obstacle avoidance are presented. In the next part, a search dealing with Framework ROS is written. The individual movements performed by the robot are then described and testing on the real robot is carried out at the end.

Design of a small mobile robot for educational purposes
Železník, Gabriel ; Huzlík, Rostislav (referee) ; Zuth, Daniel (advisor)
The bachelor's thesis is focused on the design solution for a small educational mobile robot, with the possibility of producing most of the parts using 3D printing. The work is divided into research, design and implementation. The research part briefly describes a classification of the robot and the division of its individual subsystems. The research also describes three commercially available kits and the principle of 3D printing. The design part is reflected in the choice of electronics and gradually discusses the individual design solutions, including the design of API. The last part of the implementation presents three modifications based on the design, which are supplemented by notes for printing from various materials.
