Design of an experimental stand for three-dimensional image acquisition
Mužný, Lukáš ; Pochylý, Aleš (referee) ; Kubela, Tomáš (advisor)
This thesis deals with the possibilities of 3D vision. The theoretical part describes the principles of machine vision, constitutes the basic elements, description and the methods of measurement and 3D. The practical part is focused on the design of experimental workplace, which is consists of conveyor, experimental stand, industrial robot and PLC control. The system used to recognize and grasp objects undirected. Construction chapter focuses on the treatment needs of the conveyor for sensing applications and design of experimental stand with linear axis, which is equipped with camera and lasers. Furthermore solved by a communication network between the elements of work includes the design of their communications with the description of the control of its individual elements.

Design of linear axis for heavy machine tool
Dostál, Martin ; Marek, Jiří (referee) ; Hermanský, Dominik (advisor)
This diploma thesis is concerned with providing a construction proposal of a linear axis X for multifunctional machining center. Moreover, this work presents characterisations of machining centers, overview of manufacturers, list of main construction components used in the linear axis, their evaluation, assessment of various options for construction, which are then explained further. These detailed construction methods include calculations with the subsequent choice of feed system component. Ultimately, final evaluation of chosen option is provided as well. Another section of this thesis is also an economical assessment and 3D model alongside with mechanical drawing.

Analysis of kinematics of a ball screw mechanism
Sladký, Adam ; Marek, Jiří (referee) ; Hermanský, Dominik (advisor)
This thesis describes the process of creating a mathematical model of the kinematics of a ball screw, based upon which a computational model was made, along with an intractive Matlab user interface that serves to provide fast analysis of some of the most important parameters of the mechanism. Functionality of the presented model was verified using specific ball screw parameters. The output of this analysis was presented, analysed, and results describing the influence of operating conditions on the mechanism were derived from it. These results are one of the outputs of this thesis. Both the mathematical and computational models can serve as a tool for ball screw designers and manufacturers, and not only in their current state. They can also provide a starting point for anyone that requires a kinematic analysis for a specific configuration or problem.

Energetic model of linear axis with ball screw and servodrive
Sládek, Vojtěch ; Tůma, Jiří (referee) ; Huzlík, Rostislav (advisor)
The aim of the thesis was to study the Energy Models of Linear Axes with Ball Screws and Servo Drives, to analyze the individual parts of the axis with respect to losses, the methodology of calculating the losses on the electrical part and the mechanical part of the drive and creating a complex algorithm that calculates the energy consumed for the specified motion. The thesis is divided into a theoretical and practical part, where the theoretical part is divided into the treatise on the electrical part of the axis and its losses and the part that deals with the mechanical part and its losses. The calculation is divided into the basic verification algorithm and the calculation on the given example. Each calculation is calculated for both linear acceleration and S-curve acceleration. For both types of acceleration, the result of energy and its course over time is also the waveforms of position, velocity, acceleration, angular acceleration, moments, powers, power, speed and currents over time.
