Design of docking station for mobile robot
Obšil, Tomáš ; Houfek, Martin (referee) ; Krejsa, Jiří (advisor)
The aim of this diploma thesis is design of docking station for an autonomous mobile robot Breach. The task of docking station is to connect this robotic device to power supply without human intervention in order to charge its batteries. The theoretical part of diploma thesis contains research study about autonomous charging of robots. After that it is assessed suitability of using different types of docking stations and it was chosen optimal solution. The practice part of diploma thesis contains design of docking mechanism, which takes account of inaccurate navigation of robot with deviation of several centimeters. One part of this design deals with connector system, which is dimensioned for long-term transmission of electric current with minimal value of 20 A. At the end of diploma thesis there was created 3D model of the complete docking station including connectors for charging in program called SolidWorks.

The Trilobot Model
Štěpán, Miroslav ; Janoušek, Vladimír (referee) ; Hrubý, Martin (advisor)
This MSc Thesis describes creation of motion model of mobile robot called Trilobot. This model is implemented into simple simulation tool. Some laboratory experiments with the robot are described in this paper. There is also some information about SmallDEVS tool and Squeak Smalltalk environment in which the model was implemented. Motivation of this work is effort to simplify the design and testing of navigation algorithms for Trilobot, which is available for students of FIT BUT in the robotics lab of department of intelligent systems. This simple simulation tool could partially reduce dependence on physical availability of this robot.

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.

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.

Design of watering module for mobile robot
Vizváry, Peter ; Králík, Jan (referee) ; Krejsa, Jiří (advisor)
The diploma thesis is focused on the design of a watering module for a mobile robot. The main goals of this work are to design various concepts of the watering module and their subsequent comparison, ending with the selection of the final concept, which results in its implementation in the form of a prototype with subsequent testing of its properties. The first part of this work is focused on the analysis of the issue and the definition of the assigned task together with the main parameters and requirements. The second part contains an overview of known solutions to the issue and designs for own concepts of the watering module and its individual components. The designs are compared and evaluated in terms of their performance, complexity and price. In the third part, based on the evaluation of the most promising variants, there is a selection of the final concept and after that designing and selection of the final constructional solution. The fourth part is focused on the design and implementation of the prototype, contains the selection and design of the necessary components, module assembly and the creation of the control algorithm of the watering module. The final fifth part contains testing of the functional properties of the prototype, their evaluation and subsequent suggestions for its improvement.
