Robot for Robotour 2010
Kubát, David ; Zbořil, František (referee) ; Rozman, Jaroslav (advisor)
The objective of this master's thesis was to get acquainted with an autonomous outdoor robot competition - The Robotour and further to study the capabilities and information about a robot designed on the DITS FIT Brno VUT. Next part of the project was to study various planning and localization algorithms and to make a proposal of a functional solution, allowing the robot to participate in the competition. To be specific, the goal of this work was to use the acquired knowledge for implementation of an antonomous software so the robot can start in the year 2010 race. The solution also included several related mechanical modifications. The final solution fulfills all the competiton rules and is capable of taking part in this year's plant.

Large-scale mapping of the St. Kilian Island near Davle with emphasis on comparison with existing data
Kradijan Seider, Filip ; Lysák, Jakub (advisor) ; Šedová, Adéla (referee)
The bachelor thesis aims to topographically map the island of St. Kilian near Davle, with emphasis on usage of own data. Modern methods of spatial data collection (drone photogrammetry) and processing were used. The site is mapped mainly due to the former presence of important monastery and the significant changes of local landscape in the last century. The historical state of the island has already been modelled, but today's models only include the terrain of the island. The emphasis of the thesis is on mapping the remains of the Ostrovský klášter Monastery, creation of digital models of the terrain of the island and the adjacent Vltava river bottom and subsequent large-scale cartography. The work describes the history and current state of the site and existing older data. The methods used to acquire spatial data and the cartographic aspects essential for the site map are outlined. The practical part presents the data and their processing, completion utilizing a field survey, comparison with historical data and map production, using the ArcGIS platform. Limited use is made of scripting using the ArcPy library. Keywords: Ostrov sv. Kiliána (Davle), the Ostrovský klášter monastery, drone photogrammetry, sonar, spatial data comparison

Microwave radar sensor data processing focused on detecting the trajectory of people
Uher, Adam ; Slováček, Miroslav (referee) ; Valach, Soběslav (advisor)
This bachelor ‘s thesis deals with a topic of people detection and tracking their movement in regions of interest. The individual methods that can achieve people detection are analyzed. To implement people detection and tracking their movement microwave radar sensor IWR6843AoPEVM from Texas Instruments is chosen for this task. This hardware and its software are described in detail. Then simulation is conducted to track people in a queue and its results are evaluated. Different advantages and disadvantages of individual methods are compared with each other. Finally, there’s a summary of possible implementations for this device and target platform is chosen to verify its functionality.

Sonar design in Old World bats: patterns of specialisation
Staňková, Markéta ; Horáček, Ivan (advisor) ; Lučan, Radek (referee)
Echolocation ranks among key components of adaptive setting of bats. It enabled them to evolve a plethora of diverse foraging strategies and exploit an enormous spectrum of food resources for which they represent one of the most diversified groups of terrestrial mammals with a cosmopolitan distribution. Evolution of echolocation proceeded via responses to diverse constraints and factors, both intrinsic and extrinsic, that effect particular variables of echolocation biology. The present bachelor surveys, based on literary records, briefly some of these effects and their role upon structure of bat communities. I summarize basic characteristics of echolocation types, influence of Doppler shift, strategy and use of echolocation in different environments and adaptation against defensive abilities of a prey. Among other I provide an account of history and evolution of bat detectors, the instruments essentially improving current study of that topics. Keywords: Bats, echolocation, sonar, diversity, adaptation, Old World

Overview of resources for non-destructive research underwater
Bohadlo, Antonin ; Vondrášek, David (advisor) ; Dvorský, Jaroslav (referee)
Title: Overview of resources for non-destructive research underwater. Objectives: The aim of the bachelor thesis is to define and compare the use of individual devices used for searching objects under the water based on the study of professional literature. Methods: The thesis is realized as an overview study analyzing available literature dealing with underwater research. Both literary and internet sources were used to obtain relevant resources. Results: The result is an evaluation of devices for searching underwater objects for their intended use and the object they are looking for. Keywords: Diving, metal detector, magnetometer, sonar, sediment sonar

Use of a research sonar to determine sediment thickness
Borovec, Jakub ; Vrzák, J. ; Knotek, J.
The study summarizes research results aimed at the identification and quantification of sediments in freshwater reservoirs. An algorithm for the interpretation of sonar data, and the calculation of sediment thickness as well as for the estimation of basic sediment characteristics was developed. A device for the collection of sediment cores, which are used for the calibration of sonar output data was introduced.

Safe Flight-Control of Drone Based on Sonar Measurements
Benkő, Krisztián ; Maršík, Lukáš (referee) ; Beran, Vítězslav (advisor)
Bachaleor's thesis describes design, implementation and testing of anti-crash system for safe flight-control of quadcopter. The system is implemented using ROS framework, where input data from sonars and keyboard are processed, calculation is then performed, output of which is controlling motors. Quadcopter is able to move safely in indoor environment. The emphasis was on speed of calculation and system testing. The quadcopter can be controlled by keyboard.

Quadrotor altitude stabilization
Ligocki, Adam ; Kříž, Vlastimil (referee) ; Gábrlík, Petr (advisor)
The aim of this thesis is to design and implement a vertical stabilization for drone developed at the Department of Control and Instrumentation of the Faculty of Electrical Engineering and Communication. Work gradually deals with summary of already existing solutions of already existing projects, analysis of individual sensors possible to be applied in this project and evaluate their pros and cons for measuring the flight altitude. It also deals with the mathematical apparatus suitable for processing altitude data and the design and implementation of the controller for the movement of the drone in the vertical axis. The conclusion summarizes the results achieved on real hardware.
