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.

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.
