Affordable Motion Tracking System for Intuitive Programming of Industrial Robots

The paper deals with a lead-through method of programming for industrial robots. The goal is to automatically reproduce 6DoF trajectories of a tool wielded by a human operator demonstrating a motion task. We present a novel motion-tracking system built around the HTC Vive pose estimation system. Our solution allows complete automation of the robot teaching process. Specific algorithmic issues of system calibration and motion data post-processing are also discussed, constituting the paper's theoretical contribution. The motion tracking system is successfully deployed in a pilot application of robot-assisted spray painting

Cílem této bakalářské práce je přiblížení činnosti a fungování Europolu. Autor se zabývá základními pojmy týkajících se Europolu. Také se nám pokusil ukázat celou cestu, která předcházela vzniku této agentury. Dále nám přiblížil orgány Europolu, mezi které patří bezpochyby ředitel a Správní rada. Nejvíce času věnoval problematice spolupráce Europolu s jinými organizacemi, která je dle autorova názoru v dnešní době nejdůležitější. Rozebere spolupráci jak v rámci Evropské unie, tak i v rámci celého světa. Důležitá byla taktéž kapitola, která se týkala přínosů pro občana České republiky, kde autor taktéž zmínil náklady pro občana. Závěrem této práce nás seznámil s konkrétně úspěšnými akcemi, na kterých se Europol podílel.ObhájenoThe aim of this bachelor thesis is to approach the activities and functioning of Europol.

Robustní řízení pohybu pružných elektromechanických soustav

Disertační práce se zabývá problematikou řízení pohybu elektromechanických systémů s kmitavou dynamikou způsobenou poddajností poháněné soustavy. Cílem je vyvinout efektivní a spolehlivé algoritmy pro automatickou identifikaci systému a návrh robustního regulátoru použitelné pro široké spektrum průmyslových aplikací sysémů řízení pohybu. Dosažené teoretické výsledky jsou popsány ve třech sekcích věnovaných automatické identifikaci, pasivnímu tlumení vibrací s použitím metody tvarování vstupní veličiny a aktivního zpětnovazebního tlumení. Použití navržených metod je demonstrováno řadou numerických simulací a experimentálních výsledků.ObhájenoThe main topic of the thesis is a problem of motion control of electromechanical systems with oscillatory dynamics caused by a mechanical compliance of the driven load. The goal is to develop effective and reliable algorithms for automatic system identification and robust controller synthesis applicable to a wide range of industrial motion control systems. Achieved theoretical results are described in three distinct sections devoted to automatic identification, passive vibration damping using input shaping method and active feedback vibration control. Numerical simulations and experimental results demonstrate successful employment of the developed methods

Vibration damping in gantry crane systems: Finite horizon optimal control approach

The paper deals with the problem of anti-sway control in human-operated gantry cranes. The goal is to design a suitable algorithm aiming at minimization of unwanted transient and residual oscillations of the manipulated load. A finite horizon optimization is adopted for the derivation of an optimal open-loop control strategy. The novelty of the proposed approach comes from the combination of model-based predictive control and zero-vibration input shaping methods. This allows utilizing some key advantages from both fields in terms of performance, robustness, constraints definition and simplicity of implementation. Experimental case study demonstrates the proposed approach and compares it to conventional input-shaping method

PI Plus Repetitive Control Design: H-infinity Regions Approach

The paper deals with a class of plug-in type repetitive controllers intended for servo systems which follow periodic reference signals or compensate periodic exogenous disturbances. Proportional-integral (PI) feedback controller is complemented by an internal model of a generic periodic signal aiming at perfect asymptotic tracking or disturbance rejection. A novel design method is proposed allowing a simultaneous tuning of the PI controller and the repetitive control part. The design requirements can be formulated in the frequency domain as proper loopshaping inequalities defining constraints on important closed-loop sensitivity functions. These constraints are translated directly into the parametric plane of the controller allowing to derive a complete set of admissible controllers. The proposed method is demonstrated in a case study of a flexible motion system
