Návrh zkušebního zařízení nové generace pro dlouhodobé zkoušky univerzálního aktuátoru

STREJC, Jakub January 2017 (has links)
Actuators are a fundamental part of many modern devices and machines nowadays. Typically, they are responsible for operation of various machine parts, for instance correct performance of flaps and valves. Since actuators are an important device, it is crucial and beneficial to pursue development and testing of this component. This Master's thesis focusses on the selection and construction of a test bench used for long-term tests of a universal actuator (General Purpose Actuator), widely used in automobile industry. The main reason for assigning this practical task is the unsatisfactory current type of the test bench, which does not comply with the modern testing demands of the requesting company.

Řízení pohonů průmyslového robotu pomocí systémů KEBA / Control of industrial robot drives by KEBA systems

Heinrich, Martin January 2017 (has links)
This diploma thesis deals with the implementation of the KeMotion control system of KEBA company for industrial robot KUKA KR 15/2. It gets to work original robot's drives KUKA with this new system. There was a communication network built up to operate the system itself. It was created between driving system component. Next step was a creation of the connection between control case and a new control system especially robot link up feedback. Later on there was a control programme for PLC created and adjusted including configuration of drives and converter. There was a need to find out the resolver parametr to this settings That one is used to the indirect measurement.

Časovač pro RC modely / Timer For RC Models

Fišer, Ondřej January 2018 (has links)
This paper describes complete design of timer for RC models. Described timer has three PWM outputs. With these outputs it is possible to connect two independent servo-motors and engine controller. 1 signal. The whole is controlled by 8-bit microprocessor. The time records are stored in external EEPROM, that can be programmed using I2C. Paper further discuss design of programming, which can be easily programmed the memory of EEPROM by the PC or smartphone. The goal of this paper is to design and build high quality RC timer with accessories.

Användarreplikerande robotarm med 11 frihetsgrader / User replicating robotic arm with 11 degrees of freedom

Franzén, Mattias, Nordh, Petter January 2021 (has links)
Målet med uppsatsen är att skapa en användarstyrd robotarm med många frihetsgrader. Ämnen som studeras är elektronik, reglerteknik, datateknik, samt 3D modellering. I rapporten tas det upp allt från teoretiska delar, till montering, samt testning. Den färdiga robotarmen har elva frihetsgrader och kan greppa och hantera lättareobjekt, med viss stabilitet.

Řízení 6-ti osého robota v RTOS / 6 axis robot control in RTOS

Václavek, Miroslav January 2009 (has links)
The thesis deals with the analysis, software design and the study of 3D kinematic model of robotic manipulator ROB 2-6. It creates the control software for this manipulator, containing user interface based on MFC applications. Moreover, the thesis is concentrated on the solution of various problems, e.g. non-linearity of servomotor or the limitation of manipulator´s attainability. Finally, it poses a documentation of the single project and offers new possibilities of further development in the control of this manipulator.

Řídicí a senzorický systém malého průzkumného mobilního robotu / Control System of Small Mobile Robot

Rysnar, Jiří January 2011 (has links)
This master’s thesis elaborates on the control of a wheeled mobile robot and its sensor system. The sensors provide information about distances of obstacles in its surroundings and orientation in area. The communication is realized by radiomodems, commands and data are sent by serial link between microncontroller and the PC.

Revolverová hlava pro dlouhotočný automat s elektricky ovládaným indexováním / Turret Head for CNC Sliding Headstock Machine with Electrical Control Indexing

Úšela, Tomáš January 2008 (has links)
Imposition of my diploma thesis is replace current fluid motor that the derive benefit from to indexing turret head behind electrically driven motor in the sliding headstock machine with indication KMX 326 C. Suggested system must be the most toughest and have to correspond with all the dated up parameters for cutting. Integral part of structural design is also becomingly select accurate blocking a turret head. Fluid motor substitutes behind electrical drive from next reasons: - high transmission loss on energy - sensitivity to cleanness liquid - characteristics mechanism depend upon features liquid ( thermal expansivity, fadeaway)

Pohon regulačního kruhu PVE Merkersbach / Drive of control ring PVE Merkersbach

Skoupý, Jiří January 2008 (has links)
This thesis is focused on determination of forces acting to regulation ring of water power plant Markersbach (Germany). Solution of the problem is realized for two variants of servomotors – with and without servomotors acting surfaces balancing. Next topics of this thesis are strenght calculation of piston rod and bottom of the servomotors. Minimalization of the size of servomotors plungers by change of regulation kinematics has been done and minimal pressure in the pressure tank is determined. At the conclusion of this thesis received results are mentioned and its interpretation has been done. This thesis is provided for company Litostroj Power, ČKD Blansko Engineering, a.s.

Projekt Regnbåge

Andersson, Henrik, Olsson, Carl-Philip January 2012 (has links)
Det här examensarbetet bygger vidare på en tidigare konstruerad prototyp, ett interaktivt konstprojekt där två plattor, placerade på en båge, med vattenmunstycken i mitten styrs med en joystick. Plattorna följer joystickens rörelse med hjälp av servomotorer.Målet i detta examensarbete var att koppla åskådarens smarta mobiltelefon till konstprojektet. Åskådaren ska kunna styra konstprojektet genom att vinkla sin mobiltelefon. Även vattenflödet ska kunna kontrolleras och all interaktion ska ske via trådlös kommunikation.Målet har uppnåtts genom att användaren installerar en applikation som skapats för operativsystemet Android. Applikationen skickar information om mobiltelefonens aktuella vinkelposition till en server via ett trådlöst nätverk. Servern skickar i sin tur vidare denna information till en Wifi-modul kopplad på ett arduinokort som ställer in plattornas servomotorer i rätt läge. Rapporten beskriver hur tekniken för att nå målet fungerar och illustrerar även hur prototypens design och funktionalitet har förändrats för att få ett mer effektfullt intryck. / In this thesis we further develop an existing prototype. The prototype is an interactive art project where two plates with water nozzles in the middle are placed at each end of an arc. These two plates can be controlled directly with a joystick. The plates are following the motion of the joystick using servo motors. Our main goal is to allow spectators of the art project to remotely control the plates and the water flow by using their own mobile phone.Our goal has been achieved by creating an Android application that the user can download and install directly on their mobile phone. The application automatically sends information about the angular position of the phone to a server. Then the server forwards this information to a Wifi-module connected to an Arduino board which is moving the servo motors, attached to the plates, in the correct position.This thesis describes the technique used within the project and also illustrates how the design and functionality of the prototype has been changed to make a more striking impression on the audience.
