Localization system for mobile robot B2
Korytár, Lukáš ; Věchet, Stanislav (referee) ; Krejsa, Jiří (advisor)
The master’s thesis implements localization and navigation routines for mobile robot B2 in order to operate autonomously in an environment described by a road map only. The ROS framework was used for developing new software. The research part describes possible approaches to localization problem and summarizes ROS packages with localization and navigation software. The following part includes communication with the robot’s sensor modules and data processing from LIDAR, IMU and camera. The localization package robot_localization based on Kalman filter is implemented and setting of the navigation stack navigation is proposed, aiming to robot’s autonomous outdoor navigation. Implemented functions were tested in park environment and they are evaluated in this master's thesis too.

Mobile robot in smart house
Kuparowitz, Tomáš ; Richter, Miloslav (referee) ; Petyovský, Petr (advisor)
Aim of this thesis is to search the market for suitable autonomous robot to be used by smart house. The research in this work is partly done on the range of abilities of smart houses in matter of sensor systems, ability of data processing and their use by mobile robots. The output of this thesis is robotics application written using Microsoft Robotics Developer Studio (C#) and simulated using Visual Simulation Environment. Main feature of this robotic application is the interface between robot and smart house, and robot and user. This interface enables employer to directly control robot's movement or to use automated pathfinding. The robot is able to navigate in dynamic environment and to register, interact and eventually forget temporary obstacles.

Autonomous Robot Control System
Pilát, Ondřej ; Obdržálek, David (advisor) ; Bureš, Tomáš (referee)
This master thesis describes the design and implementation of control sys- tem for autonomous robot which is able to run through user defined points in unknown environment without colliding with obstacles. The work contains analysis of the available hardware and software solutions, modular design with control system implementation divided into separate subsystems (control, lo- calization, route planning, driving the robot using Hermit curves and low-level hardware control). The work also contains explanation of rework of the school robotic platform. The implementation was tested on a created robotic platform. Driving the robot along the Hermit curve allows smooth and in some cases quicker passage through defined points, than passage consisting of rotations on the spot and direct movements. 1

Exploiting GPS in Monte Carlo Localization
Marek, Jakub ; Obdržálek, David (advisor) ; Koubková, Alena (referee)
This work presents two approaches for integrating data from a low cost GPS receiver in a Monte Carlo localization algorithm. Firstly, an easily applicable method based on data in the standard NMEA protocol is shown. Secondly, an original algorithm utilizing lower level pseudorange measurements accessed in binary receiver-specific format is presented. In addition, a set of tools for analysis of GPS measurement errors on receivers with SiRF III chipset was implemented

Prostředí pro vývoj modulárních řídících systémů v robotice
Petrůšek, Tomáš ; Obdržálek, David (advisor) ; Plch, Tomáš (referee)
The subject of the thesis is the design and implementation of a modular control system environment, which could be used in robotics. Both autonomous and guided robots are supported. The higher-level software com- ponents like localization, steering, decision making, etc. are effectively sepa- rated from the underlying hardware devices and their communication protocols in the environment. Based on the layered design, hardware-independent algo- rithms can be implemented. These can run on different hardware platforms just by exchanging specific device drivers. Written in C++ using standard libraries, the final software is highly portable and extensible. Support for new platforms and hardware modules can be implemented easily. The whole sys- tem was tested on two robots and the particular instances of the systems built using this development environment are included in the solution and partially described in the thesis.

Autonomous mobile robot
Pijáček, Ondřej ; Kopečný, Lukáš (referee) ; Jílek, Tomáš (advisor)
This thesis describes the design and implementation of chassis for autonomous wheeled mobile robot along with a proposal for a suitable control system. To move the robot was necessary to create individual modules for measuring environmental data, its subsequent processing and power management. For the entire robot system capable of rapid interaction, certain tasks are separated and controlled by its own microcontroller. For communication between the modules were chosen and designed SPI bus communication protocol. Thus assembled chassis then communicates over a serial line with higher system from which acquires data indicative of a subsequent procedure. The result is a controlling system communicating between its parts. Part of the design is also defined communications protocol that transmits data on the one hand and also used for fault diagnosis when sending information. Furthermore, there are patterns and specific methods for controlling the individual modules. In conclusion, the thesis described the proposed testing the robot in real conditions, along with the measurement results obtained in the task of autonomous driving.

A proposal for two wheeled autonomous robot
Hess, Lukáš ; Marada, Tomáš (referee) ; Zuth, Daniel (advisor)
The goal of this diploma thesis is a proposal of autonomous two wheeled balancing robot, differentially driven. This kind of robot is especially suitable in confined space, where it can utilize its maneuver skills. Many criteria as operational conditions, materials, size and weight of the robot, suitable hardware and sensors must to be considered, when designing the robot. Development and implementation of autonomous balancing control system is also part of the thesis.

Design of autonomous mobile robot.
Vodrážka, Jakub ; Marada, Tomáš (referee) ; Věchet, Stanislav (advisor)
The thesis deals with design of the device for testing the localization techniques for indoor navigation. Autonomous robot was designed as the most appropriate platform for testing. The thesis is divided into three parts. The first one describes various kinds of robots, their possible use and sensors, which could be of use for solving the problem. The second part deals with the design and construction of the robot. The robot is built on the chassis of the differential type with support spur. Two electric motors with a gearbox and output shaft speed sensor represent the drive unit. Coat of the robot was designed for good functionality and attractive overall look. The robot is also used for the presentation of robotics. Thesis provides complete design of chassis and body construction, along with control section and sensorics. The last part describes a statistical model of the robot movement, which was based on several performed experiments. The experiments were realized to find any possible deviations of sensor measurement comparing to the real situation.

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.
