Měření pozice pohybujících se objektů pomocí robotické totální stanice / Position measurement of moving objects using a robotic total station

Horeličan, Tomáš January 2021 (has links)
Práca sa zaoberá objavujúcim sa nekonvenčným využitím moderných teodolitov, tiež známych ako Robotické Totálne Stanice (RTS), ako sledovací a navádzací systém, určením presnej pozície dynamicky sa pohybujúceho objektu. To sa týka najmä situácií, kde nie je možné využiť konvenčné polohovacie systémy akým je napríklad GNSS. Kinematicky určená poloha objektu kontinuálne sledujúcou RTS môže byť následne v reálnom čase využitá pre autonómnu navigáciu malých bezpilotných leteckých prostriedkov (UAV) poskytnutím referenčného súradnicového systému a okamžitej polohy v ňom. Podstatná časť práce je venovaná návrhu a realizácii vhodných experimentov, ktoré overia spoľahlivosť určovania presnej polohy objektu v presnom časovom okamžiku. Boli preverené stanice série S7 a S9 od spoločnosti Trimble a stanica S9 HP, ktorá disponuje frekvenciou kontinuálneho merania až do 10 Hz bola napokon využitá pre experimenty. Lokálny čas ovládacieho panelu TSC7, ktorý zabezpečuje komunikáciu so stanicou bol pomocou protokolu PTP synchronizovaný s lokálnym časom mini-počítača Raspberry Pi, ktorý následne poskytoval referenčné meranie skutočnej polohy objektu v čase. V závere sú zhrnuté výsledky experimentov.

Virtuální zprovoznění robotizovaného pracoviště pro obloukové svařování / Virtual commissioning of the robotized workplace for arc welding

Adolt, Lukáš January 2021 (has links)
This diploma thesis is focused on the design of a robotic workplace for arc welding and its subsequent virtual commissioning. The summary deals with knowledge from industrial robotics and arc welding, the system analysis is focused on the composition of the workplace and the principle of arc welding, including acting influences. In the practical part, several variants of the solution are proposed, the most suitable variant is processed in the form of a 3D model. This model is then simulated, including all processes, a control program is created, and virtual commissioning of the workplace is demonstrated.

Digitální zprovoznění robotizovaného pracoviště pro studený nástřik rotačních dílů / Digital commissioning of robotized workplace for cold spraying of rotating parts

Šimůnek, Petr January 2021 (has links)
This work deals with the virtual and later real commissioning of the workplace for cold spraying of rotating parts, which is located in the laboratories of the Institute of Materials Science and Engineering, Faculty of Mechanical Engineering, Brno University of Technology. The workplace put into operation in this way serves the employees of the mentioned institute for experimental activities in the field of cold spraying. The theoretical part of the thesis describes all the essentials associated with virtual commissioning and the theory of cold spray. The practical part then deals with the creation of a robotic program, including the user interface, which is used to control the workplace. Part of this diploma thesis is also the realization of the connection between the external motor driver and the robot controller via the PROFINET communication bus.

Fuzzy modely map pro pohyb mobilních robotů. / Fuzzy map models for mobile robots

Machek, Ondřej January 2011 (has links)
This master thesis present a method for building topological maps for mobile robot navigation using neural network and neural fuzzy network. The master thesis concentrates on classification method. Neural fuzzy network is compared with two neural networks. It was also designed control algorithm exploration environment for autonomous mobile robot. This will rereduce the time to build the map. I developed simulation program in Matlab, which simulate move mobile robot in unknown environment.
