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.

Navigation of B2 mobile robot in outdoor environment
Hoffmann, David ; Věchet, Stanislav (referee) ; Krejsa, Jiří (advisor)
This master’s thesis deals with the navigation of a mobile robot that uses the ROS framework. The aim is to improve the ability of the existing B2 robot to move autonomously outdoors. The theoretical part contains a description of the navigation core, which consists of the move_base library and the packages used for planning. The practical part describe the aws of the existing solution, the design and implementation of changes and the results of subsequent testing in the urban park environment.

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.

Simulation of Autonomous Mobile Robots
Janoušek, Radim ; Burian, František (referee) ; Lázna, Tomáš (advisor)
The goal of this work is to implement robotic algorithms for autonomous tasks. The thesis starts with an introduction to the ROS 2 framework, where the basic features of this framework are introduced. This is followed by a comparison of the most popular robotic simulators, including a more detailed description of the Gazebo simulator and the lesser known Webots simulator. The next chapter focuses on the reasons for choosing the Webots simulator for creating the simulated world and describes the process of creating the interior based on the template. The penultimate chapter discusses the creation of robotic platforms in the Webots simulator and the sensors used, including the simulated lidar. In this simulation, the lidar is created with a mock-up of the real device. In the last chapter, the drivers for controlling the robotic platforms are implemented and a package for ROS 2 is created.

Design of autonomous robot for cleaning solar panels
Kuchárik, Martin ; John, David (referee) ; Křenek, Ladislav (advisor)
The main objective of the diploma thesis is the design of the concept of an autonomous robot intended for the cleaning of photovoltaic panels in solar parks. The proposal aims to respond to current market events, which demonstrate that the global shift to renewable sources of energy goes in line with the exponential growth of photovoltaic construction. Solar panels require regular maintenance, and that is what cleaning robots are used for, yet they currently have a variable form. The diploma thesis focuses on creating a concept of an innovative versatile self-driving cleaning vehicle powered by sustainable energy sources. The proposal introduced within this diploma thesis takes ecological aspects into consideration with the emphasis on aesthetics, purposefulness and intuitive usage.

Design of Model of a Walking Autonomous Mechanism and its Simulation of Movements in Difficult Terrain
Szabari, Mikuláš ; Jánoš,, Rudolf (referee) ; Bobovský,, Zdenko (referee) ; Knoflíček, Radek (advisor)
The first part of the work is devoted to the current state, which discusses the design and step cycles of legged mechanisms and also the resistant terrain. The following second part critically evaluates the current state and defines the solved problem. The third part sets specific goals and creates a work procedure. The solution of the work follows by fourth part, which realizes the morphological analysis of the structure of the legged mechanism and the analysis of the resistant terrain in which the mechanism moves. The fifth part is devoted to the creation of models of legged mechanisms, its initial test and the choice of a specific construction of a legged mechanism for resistant terrain. The following sixth part simulates the movement of the legged mechanism and deals with its optimization. The simulation is confirmed by the experiment performed in the seventh part. The end of the work is devoted to contributions, discussion of results and conclusion.

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.

Comparation of the 2D LIDAR SLAM methods in the simulation and in the real world
Cihlář, Miloš ; Jelínek, Aleš (referee) ; Ligocki, Adam (advisor)
This thesis deals with the design of a mobile robotic platform with the ability to build a map with an already existing 2D SLAM algorithm and a comparison of this algorithm in simulation and the real world. It uses three known algorithms i.e. Hector slam, Gmapping, and Karto slam. The part of this work deals with the creation of two wheels differential drive robot models in the Gazebo simulator and with an implementation proposal that is realized with the ROS framework. In thesis is implemented basic localization technique for mobile robots. Planning algorithms and a path controller are mentioned. In thesis is proposed own access to an autonomous exploration of building to build a map of the building. For evaluation of the SLAM algorithm is suggested slam quality criterion.
