Design of walking mobile robot
Szabari, Mikuláš ; Knoflíček, Radek (referee) ; Kočiš, Petr (advisor)
The diploma thesis deals with the construction of a walking mobile robot, which is intended for passing through a rugged or forest terrain, whose task is to collect the sample. The first part is devoted to the review of walking robots. Follow-up an analysis of two-legged and four-leg walking robot technologies and a brief overview of drives. The second part is devoted to problem analysis and design variant. The work contains 4 design variants in the form of schemes. Using the multi-criteria analysis, the variants were evaluated and the optimal variant was chosen taking into account the representative parameters. The third part is devoted to the construction of the chosen variant, it is divided into body and leg construction. The overall design is processed in the form of a virtual 3D model. In the leg construction, the design itself, but also the calculations of drives, shafts, gears and belt transmissions are solved. The end of the thesis is devoted to drawing documentation based on 3D model and economic evaluation. Follow-up and discussion with possible continuation and use in practice.

Construction of conveyor superstructure of mobile robot MiR
Adámek, Tomáš ; Szabari, Mikuláš (referee) ; Knoflíček, Radek (advisor)
The subject of this diploma thesis is the design of a conveyor superstructure of a collaborative mobile robot MiR. The first part is a theoretical research basis focused on mobile collaborative technologies and information related to Mobile industrial Robots. The following is a practical part built on previous acquired knowledge. The key issue of the solution is the logistics transport of the PCB magazine in the field of SMT industry. There are created two structural design variants of the superstructure arrangement for the transport of two binders and the most suitable variant is selected on the basis of the multicriteria basic method. The selected alternative of the conveyor top module is then subjected to design calculations. In order to obtain a comprehensive overview of the prototype production, the following section contains drawing documentation, including relevant comments, an economic cost estimate and a risk analysis.

Design and control of the omnidirectional chassis
Rendek, Andrej ; Kočiš, Petr (referee) ; Szabari, Mikuláš (advisor)
The master's thesis deals with the design of a locomotion system of an omnidirectional robot designed for application in sandy environment. The introductory part of the thesis is an overview in the field of current solutions of omnidirectional chassis of mobile robots. The thesis continues with a choice of possible variants. The variant evaluated as the most suitable is then elaborated in detail. This includes an analysis of the resistances acting on the chassis under conditions and movements representing omnidirectional movement in the sand. Analysis is followed by a selection of drives and a design solution supplemented by stress analysis. The final part is focused on the chassis control algorithm.

Design of automated electro-polishing apparatus for electron microscopy specimens preparation
Čermák, Jan ; Szabari, Mikuláš (referee) ; Mikmeková, Šárka (advisor)
This diploma thesis deals with the automation of the electropolishing process, which is per-former as the last step in the preparation of metallographic samples intended for observation in an electron microscope. A complete hardware design of a single-purpose machine has been developed, which provides the automatic preperation of up to six samples per insertion. There was the design of a manipulator for sample handling together with chemically re-sistant sample holder suitable for automatic operation as a part of solution. The design of the whole machine was developed with regard to the safety of the operator. The thesis includes detailed 3D model of the device and the desing of an application for measurement in the LabVIEW. It describes the future working process of the machine, including a description of a software for controlling the machine and sending process data of each sample to the to the database in accordance with the principles of industry 4.0. In the conclusion, the achieved results and the proposal of further steps necessary for the realization of the machine are for-mulated.
