Ovládání robotického manipulátoru mikrokontrolérem / Robotic Manipulator Controlling Using Microcontroller

Zemánek, Martin January 2007 (has links)
This master's thesis deals with control robotic manipulator ROB 1-3 using common joystick and microcontroller HC08 NITRON or HC08 LJ12. The goal of this work was creation of module for controlling axes position of servos included in robot by analog signal coming from connected joystick. There are formed possible suggestions about connecting individual parts together for both autonomous and version using development kit. Programming code suggestion is based on these connections during further development. The limitations of using it are described in analysis and final results are shown in statistics results.

Optimalizace hydraulického systému a jeho prvků pro malá dopravní letadla / Optimization of Hydraulic System and its Components for Commuter Category Airplanes

Kameník, Luboš January 2012 (has links)
The dissertation thesis deals with optimization of the selected areas of the hydraulic system for small and medium transport aircrafts. Newly developed small aircraft EV-55 is a representative in the category of the small aircrafts . The selected areas of the hydraulic systems , important and useful for domestic producers of the hydraulic devices and whole hydraulic systems for the airplane EV-55 , are subjected to optimization efforts in the dissertation thesis. Design parameters of the hydraulic system (type of hydraulic source, level of pressure, weight of connecting tube), hydraulic devices ( tribology, machining process), simulation of the servomechanism and areas of diagnostic of technical status of the hydraulic system are optimized in the dissertation thesis.

Robot pro stolní tenis / Table tennis robot

Nguyen, Thuc Tuyen January 2013 (has links)
This diploma thesis deals with designing and manipulating a robot for training table tennis. Robot's mechanical construction is based on aluminium profiles supported by various standardized assembly units, such as rotating bearings, plain bearings, threaded rods... The front-end part of the robot, which requires better deformation property and lighter weight, was made from ABS material using 3D rapid prototyping technology. The design of the robot allows its body to rotate around three axises. Thanks to the high dynamical ability, robot can be set to throw balls to various places on the playing table, with different types of ball spin. Balls will be shot out by two rubber wheels, which are attached to two electrical DC motors. By driving the speed of the two motors, we can control the speed of the ball, as well as speed of its spin. All robot's activities are driven by an embedded system designed using microcontroller ATMega128. A firmware for controlling robot's function was writen and flashed into the microcontroller. End-users might communicate with the robot via a system of buttons and a text LCD display. The built robot was tested and it has shown its ability to throw balls to 6 different places of the playing table, at different speeds, with different types of ball spin, and different spin speed, according to the parameters set by user.

Řízení polohového servomechanismu s nespojitou přestavnou rychlostí. / Position control of servo with discontinuouns rechangeable speed

Jindra, Pavel January 2012 (has links)
Diploma thesis work includes simulation of compensation of control for discrete. The aim of the work is a solution positioning control of servomotor drive piston, which is controlled by pass of the pressure oil with the help of several electromagnetically controlled switchboards with the orifice in the output channels. The verification activities of the regulated system is done using simulation in Matlab/Simulink and Matlab/Simulink, Matlab/Hydrosim. The requirement on the created model is to verify the behavior of the system to be modified to be used for the further development of the issue

Návrh a analýza vlastností hydraulického servomechanismu řízení malého a rychlého letounu / Design and analysis of the properties of the hydraulic servo control of a small and speedy aircraft

Cäsar, Tomáš January 2017 (has links)
Target of this thesis was to design servo-mechanism suitable for control system of small and speedy aircraft, such as business jets and light multi-purpose attack aircraft. Main task was to use suggested characteristics for computer analysis and determine impact of their changes on servo-mechanism properties. Further on, experimental way of determining these parameters.
