Robot Control with Voice Commands
Hájek, Pavel ; Kapinus, Michal (referee) ; Španěl, Michal (advisor)
This bachelor's thesis describes design and development of a robot voice control application aiming at platform PR2. It explains the procecess of voice recognition and describes the robot operating system as a target platform. The application uses library Sphinx-4 to translate speech to text, which is than published in ROS. In the end, the set of tests is described. Tests discovered, that the best way to control robot with a few simple commands is developing own grammar.

Anti-crash System for Quadcopter with set of sonars
Hrazdil, Radim ; Musil, Petr (referee) ; Beran, Vítězslav (advisor)
This bachelor’s thesis is focused on installing ultrasonic sonars on a quadcopter, connecting them to the Arduino Micro microcontroller and implementing a program for controlling connected sonars. A demonstrational application using ROS framework was designed and implemented. Based on data received from sonars this application detects nearby obstacles and is able to maintain safe distance as well as slow down when getting too close to an obstacle. The design of the collision avoidance system is focused on high frequency of measurements and maximal space coverage.

Road Detection in the Camera Image
Šedo, Jan ; Luža, Radim (referee) ; Rozman, Jaroslav (advisor)
Bachelor's thesis deals with road detection in camera image. It contains overview of used methods in this area and their most frequented usage, brief introduction to image processing and to ROS framework. Then it gives proposal and details of implementation of application, which analyzes the image and performs segmentation in order to separate the road and it's surroundings by global thresholding method with use of ROS and OpenCV libraries. Application is tested on the data gathered for purposes of Robotour 2013 contest and on series of own recorded data. Finally it contains evaluation of results and discussion about future work on this project.

Robot Navigation with Differential GPS
Doležal, Jan ; Rozman, Jaroslav (referee) ; Luža, Radim (advisor)
This bachelor's thesis describes the realisation of method for improving the accuracy of GPS navigation, so-called differential GPS, and its implementation in the form of a package for Robot operating system (ROS). A programming library RTKLIB, which deals with methods of increasing the accuracy of GPS navigation, is used in the package. Created solution was subjected to measurement of precision and accuracy of calculated position. This proved that the differential GPS method provides more accurate position coordinates and makes more sense for use on robots than conventional GPS.

Robotic Mirror
Vopálenský, Radek ; Materna, Zdeněk (referee) ; Kapinus, Michal (advisor)
The aim of this work is to design and implement a module through which robotic platform PR2 repeated movements of a man standing before her. User's movement is sensed using Kinect and detected by monitoring skeletal model. The embedded module can control robotic head, robotic arms and move the base in all directions. The work describes all the technologies used, description and design solutions and test results.

User Interface for Robot Control in Object Grasping Task
Manďák, Roman ; Materna, Zdeněk (referee) ; Beran, Vítězslav (advisor)
This bachelor work is focused on design and implementation of the user interface (UI) for the control of a robot during grasping objects. Common devices as well as the less ordinary ones were used and compared for capturing user gestures of various types. The work includes an in-depth analysis of the devices which are used in robotics, a description of existing solutions which serves as a ground for application design, and rules for creating the UI. Further are described design, implementation, the experiments with the application which were conducted, and in the end the result of the comparison of control devices.

Robot Controlled by PIC Microprocessor Unit
Heřman, Petr ; Luža, Radim (referee) ; Rozman, Jaroslav (advisor)
This thesis describes design of a cheap robot. It includes implementation of firmware of low level control unit based on microcontroller PIC. The firmware drives motors, gains sensors data and communicates with the high level control unit. Furthermore the thesis presents realisation of connection to the robotic operation system ROS and its standard structures allowing usage of existing packages for the robot teleoperation and displaying sensor data on the remote computer. The thesis finally reports experiments with the robot. The constructed prototype is the model of the robotic lawn mower, however the whole solution has universal usage.

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.

Tabletop Object Detection
Varga, Tomáš ; Zemčík, Pavel (referee) ; Španěl, Michal (advisor)
This work describes the issue of tabletop object detection in point cloud. Point cloud is recorded with Kinect sensor. Designed solution uses algorithm RANSAC for plane detection, algorithm Euclidean clustering for segmentation and ICP algorithm for object detection. Algorithm ICP is modified and mainly it can detect rotational symetric objects and objects without any transformation against it's models. The final package is build on platform ROS. The achieved results with own dataset are good despite of the limited functionality of the detector.

Modelling and simulation of robotic applications
Šťastný, Martin ; Heriban, Pavel (referee) ; Šťastný, Jiří (advisor)
The aim of this master thesis is to make research of Open Source software, which are used for simulation autonomous robots. At the begining is performed research of selected robotic simulators. In the first part of this work is to get familiar with robotic simulator Gazebo and robotic framework ROS. The second part of this work deals with simulating and subsequent implementation of choosen robotic tasks through the simulator Gazebo and the ROS framework.
