GPS data usability in mobile robot navigation problem
Novák, Pavel ; Věchet, Stanislav (referee) ; Krejsa, Jiří (advisor)
This work is focused on problems of the GPS/DGPS receiver precision used by mobile robot for navigation in outdoor environment. The first part deals with theoretical analysis of GPS, description of it´s functions, errors and their influence on measurements accuracy. Second part deals with practical measurements performed at two locations with different types of obstacles restricting the view to the sky and using the refining methods of measuring the DGPS or so-called differential GPS. The last part of study presents the measured results and its analysis.

Indoor Robot - Mechanical Construction and Power Electronics
Maťas, Marek ; Veselý, Miloš (referee) ; Žalud, Luděk (advisor)
The thesis is divided into several logical units. In the first part is described the topic of mobile robotics, construction, propulsion and control of mobile robots. Other parts are devoted to the design of robot’s mechanical structure, calculating the requirements for the proposed type of engines and drives. Finally, the control electronics for these engines is proposed, along with a program for microcomputer.

Sensor Calibration for Multispectral Data Fusion in Mobile Robotics
Kalvodová, Petra ; Hanzl, Vlastimil (referee) ; Mazal,, Jan (referee) ; Pospíšil,, Jiří (referee) ; Weigel, Josef (advisor)
Thesis deals with data fusion and calibration of sensory system of Orpheus-X3 robot and EnvMap mapping robot. These robots are parts of Cassandra robotic system that is used for exploration of hazardous or inaccessible areas. Corrections of measured distances are determined for used laser scanners Velodyne HDL-64, Velodyne HDL-32 and range camera SwissRanger SR4000. Software MultiSensCalib has been created and is described. This software is used for determination of intrinsic parameters of heterogeneous cameras of the sensory head and for determination of mutual position and orientation of these sensors. Algorithm for data fusion of CCD camera stereo pair, thermal imager stereo pair and range camera is proposed. Achieved calibration and data-fusion parameters are evaluated by several experiments.

Robot navigation by means of graph-based algorithms
Čížek, Lubomír ; Krček, Petr (referee) ; Dvořák, Jiří (advisor)
This thesis deals with robot path planning by means of graph-based algorithms. The theoretical part contains basic approaches to robot path planning, and pay closer look at various methods of graph-based algorithms. In the second part of this thesis a simulation environment for robot navigation was created in C#. And in this environment chosen methods of graph-based algorithms have been implemented. This thesis was written within the research project MSM 0021630529: Intelligent systems in automation.

Differential chassis mobile robot trajectory planning
Chochel, Michael ; Věchet, Stanislav (referee) ; Krejsa, Jiří (advisor)
This work speaks about a suggestion of trajectory of mobile robot with nonholonomic movement limits and differential chassis while passing through a “T“ shaped crossroad. In the theoretical part some methods generally used to solve this task of planning a trajectory of the robot will be explained. In the practical part this task will be solved by an algorithm for searching the optimal trajectory to pass through the crossroad.

Control of mobile robot
Vožda, Ondřej ; Skula, David (referee) ; Šembera, Jaroslav (advisor)
This thesis describes questions of developing the system for remote and presence control of a mobile robot (wheelchair). It is concerned with choice of a proper protocol for communications via wireless network, transmission of images from webcam and data from joystick. Next objective of the thesis is recognizing surrounding obstacles using ultrasonic range finders. Thesis describes observation arisen from using this type of sensors. One of the most important points of the thesis is to discuss the safety of usage of the developed system. In conclusion, possibilities for future development are stated.
