Energy analysis of motor pump units
Čenč, Samuel ; Štigler, Jaroslav (referee) ; Klas, Roman (advisor)
The bachelor thesis includes description and classification of hydraulic pump units. Individual types of hydraulic pumps, their area of use, advantages and disadvantages, and the method of regulating the output hydraulic parameters are described here. The thesis also includes a brief description of electric drives, whcich are used as a source of mechanical energy to drive hydraulic pumps. The purpose of the first part is to point out that there are two main ways of regulating the output hydraulic parameters. This is the regulation by changing the geometric volume of the hydraulic pump and the regulation by changing the speed of the electric motor. In the main part of the bachelor thesis attention is paid to individual conceptual solutions of hydraulic pump units. The essence of the regulation of hydraulic variables, the principle of operation of regulation in selected representatives regarding their dynamics is explained here. This is followed by experimental verification on real representatives of hydraulic pump units, which enables a deeper insight into the issue of hydraulic power units regulation and the course of electrical and hydraulic variables during the transient state.

Smart materials application in hydraulic systems
Montag, Jakub ; Klapka, Milan (referee) ; Kubík, Michal (advisor)
This thesis deals with the application of smart materials in hydraulic systems. In the first part, the hydraulic systems themselves and smart materials are described. This is followed by specific smart materials, where the principle of function, in which fields they can be found, applications in hydraulic systems and their advantages and disadvantages are described. Finally, the materials are summarised and compared with each other.

Robotic hand
Pizúr, Lukáš ; Levek, Vladimír (referee) ; Šteffan, Pavel (advisor)
The aim of this work is to design a robotic hand, which will be controlled by wireless Wi-Fi, will be equipped with a camera and for easier operation will be designed control glove. The first part of the thesis is a theoretical analysis, various variants of sensors are described, which can be used for motion detection, each drive units and their control. Next chapters are focused on used electronic modules and microcontrollers. The second part is practical and is focused on the mechanical design of a five-finger robotic hand and fixing to a robotic arm. Also described is the control electronics of the entire robotic hand and the programmed firmware. Next, the design and implementation of the control glove is described. The last chapter describes the programmed application for the Android operating system.
