Srovnání lokalizačních technik / Comparison of Localization Techniques

Skalka, Marek January 2011 (has links)
This work compares localization techniques used in mobile robotics. Localization - how to determine one's own position within a space - is one of the fundamental challenges of robotics. The introduction is devoted to a detailed description of localization and to the categorization of localization techniques. In subsequent chapters, category by category, various localization techniques and their variants are described and their strengths and weaknesses are compared. The work successively addresses: probabilistic localization techniques used for inaccurate sensor measurements processing and for providing reliable position estimate; relative localization techniques used for evaluation of relative changes in the robot position; and absolute localization techniques for finding and estimating the absolute position of the robot in the environment.

Integrace plánování a rozvrhování / Integrating Planning and Scheduling

Dvořák, Filip January 2014 (has links)
The main topic of the work is the design and development of a plan-space planning system FAPE that integrates explicit time reasoning, resource reasoning with discrete resources and reservoirs and hierarchical decompositions. FAPE is the first planning system that accepts the language ANML, supporting most of its major features. We investigate different aspects of the integration, also proposing a new problem reformulation technique for the state-variable representation and discovering a transition of performance between sparse and minimal temporal networks. We further extend FAPE with acting capabilities and evaluate the runtime properties and benefits of its expressiveness. Finally, we present FAPE as a planning and acting system in real world experiments, where FAPE operates a PR2 robot. Powered by TCPDF (www.tcpdf.org)

Modelování a řízení mobilních kolových robotů / Modelling and control of wheeled mobile robots

Sypták, Michal January 2009 (has links)
Control of wheeled chassis does not constitute a problem in the area of mobile robotic solely. Rather, it can be encountered in transportation, both at close range and long range. In this thesis, mobile chassis are characterized as kinematic models. These models prove to be erroneous at high speed, whereas they sufficiently accurately represent the real robotic system in situations when slow, autonomous motion of the robot is desired. In comparison with dynamic models, both their project and implementation are simpler, too. The first part of this thesis is focused on a basic description of the motion of a robot in-plane. In the next part, five, most frequently used wheels in robotics are described and characterized - standard fixed wheels, standard steering wheels, castor wheels, multidirectional wheels and omnidirectional wheels. The motion conditions are deduced from each type of wheel. There are two methods of projecting the mobile robot model – full modelling and generic modelling. Based on these two methods, six models of mobile robots with different motion properties are proposed and described. The last and most extensive part of this thesis deals with simulator of robot motion created in Matlab/Simulink. It includes users guide which allows the configuration of random chassis and various trajectories of motion. In this way, it is possible to visually evaluace and classify the the different types of robots. The core of this thesis is largely connected with the field of odometry – i.e. transformation output from speed sensor and turning of wheels sensor into the robot position in the system of coordinates that defines its working space. Simulator as complex only model motion of mobile robots in plain. Its inside structure included algoritms, that have been used in praxis for control real mobile robots. In this way created Simulator models the motion of mobile robots in-plain only. However, its inside structure is based on algorithms, that could be used for control of real mobile robots in real-life working.

Rojová inteligence v MRDS / Swarm Intelligence in MRDS

Kučera, Lukáš January 2012 (has links)
The background research in this Master’s thesis is focused on swarm intelligence. Further, there are two experiments described. They are based on released publications and they study behaviour of a group of robots during a puck gathering and during a target search. The actual thesis follows a repetition of these experiments in Microsoft Robotics Developer Studio (RDS), a free robotics simulation environment. The realization of both experiments in RDS is documented in detail and the achieved results are evaluated and compared with the results described in the publications. In conclusion, the thesis summarizes basic features, advantages and disadvantages of developing in RDS, based on a personal experience.

Model dynamické scény pro robota / Dynamic Scene Model for Mobile Robot

Görig, Jan January 2012 (has links)
This master's thesis focuses on representation of geometric information about the surrounding environment for robotic systems. Instead of a common point-cloud based representation, an environment model that stores information about objects described by bounding boxes and planes is proposed. These objects can be obtained from trained object detectors, planar surface detectors, etc. processing data from sensors (e.g. RGB-D camera). The information about the objects (position, etc.) stored in the model is constantly changing according to data obtained from detectors. The environment model is implemented as a module for Robot Operating System. To illustrate and visualize features of the model, a demonstration application was also prepared.
