Design of automatic tool change for robotic machining
Dvořák, Vít ; Vetiška, Jan (referee) ; Bradáč, František (advisor)
This master's thesis deals with the design of a station for automatic tool change for robotic machining at the UVSSR CELL robotic workplace. This workplace is located in the laboratories of the Institute of Production Machines, Systems and Robotics FSI BUT. In the introductory theoretical part, robotic machining technology is briefly described, which is followed by research in the area of systems for automatic tool change. Next, individual parts of the machining cell are described. This is followed by a system analysis, in which the solved problem is analysed in detail. In the next chapter, 3 designs of the automatic exchange station are created, and the most suitable design is selected using multi-criteria analysis. The chosen design is then processed in detail in terms of construction, including the choice of tires and sensors. After that, the concept of the automatic replacement peripheral is designed and processed. which in this case is the cleaning station. After processing the structure, it is proposed to connect the electronics of both stations, including modifications in the main switchboard of the machining cell. Detailed drawing documentation of both stations and electronic wiring diagrams are part of the appendix. In the next chapter, functional blocks are designed for controlling the cycle of automatic tool change by the robot and manual tool change in the station. The proposal also includes a description of the management of selected devices. The following is a design of the HMI for handling error conditions and managing the exchange cycle. Finally, a safety assessment of manual tool change in the station is processed.

The motor drive control of the gas insulated disconnector of ABB switchgear
Kyseľ, Martin ; Ficek, Jan (referee) ; Orságová, Jaroslava (advisor)
This bachelor's thesis focuses on addressing the issue of controlling three-position disconnectors in gas-insulated switchgear by ABB. The aim of the thesis was to create drawings for three-position control methods and analyze their properties. The introduction provides a detailed analysis of the structure and components of gas-insulated switchgear. It further examines the issue of three-position disconnectors and their various control methods. The practical part of the thesis deals with the design of standardized control circuits for disconnector motor drives, which efficiently utilize space and optimize costs. The individual circuits were compared to select the most suitable replacement for the original control system. A model was created to verify the functionality of the proposed solutions, serving to demonstrate their operation.

Design of an industrial robot with six degrees of freedom
Štefek, Ondřej ; Štěpánek, Vojtěch (referee) ; Knoflíček, Radek (advisor)
The diploma thesis deals with the design, production and construction of robots with six degrees of freedom and a serial kinematic structure. In the beginning of the thesis, the individual types of robots, used gearboxes, energy media are described, and the principle of direct and inverse robot kinematics is outlined here. In the next chapters, the system approach of the robot, the selection of the optimal variant of creation, and then the kinematics and dynamics of the robot, which further follows on from the principle of the creation of castings, the design nodes of the robot and its electrical engineering and the programming of the control system, are analyzed. For the pinions and the shaft of the fifth axis, a safety analysis is carried out with respect to the limit state of elasticity. This robot design is then financially compared with a commercially available industrial robot. For the robot, among other appendices, drawing documentation, an electrical wiring diagram and a safety analysis of the robotic workplace have been prepared. The robot and the related robotic workplace are physically built in the workshops of the Institute of Production Machines, Systems and Robotics in Brno.

Semiautomatic crimping machine
Nosek, Jakub ; Stibor, Karel (referee) ; Štohl, Radek (advisor)
This thesis deals with the design, creation and testing of a new automated machine for the production of ureteral catheters for a company producing medical equipment. The work is a continuation of the diploma thesis of a student of the College of Polytechnics Jihlava, whose work only concerned the design of the mechanical part of the machine and the analysis of the actual manual production process.

Automatic generation of typical schematics in CAD/CAE system
Fiala, Jan ; Kolář, Milan (referee) ; Bátora, Branislav (advisor)
This thesis is devoted to the design of a functional solution for automated generation of type schemes based on defined input parameters of the considered structures. The first part of the thesis includes an introduction to design and basic design documentation standards, control systems with field instrumentation. Then it focuses on the selection of suitable CAD/CAE software with a more detailed description of the chosen software and some of its features. The practical part first introduces the generated parts and the modifications to the initial schematics and documentation required to support automated generation. The process is presented with the generation procedure using concrete examples of documentation. The output of the thesis is represented on two sample projects that includes generated schemas using the proposed methodology.

Possibilities of usage of computational systems for switchgear assembly design
Stejskal, Lukáš ; Ing. Jan Krejčí (ext.) (referee) ; Valenta, Jiří (advisor)
The main goal of my bachelor's thesis is to descriebe the CAD systems that are used by engineers to design the electric switchboard and the electric network. In my thesis I descriebed the main options of these systems. The other thing is which data formats are supported for data export and import. In the second part of my thesis I'm dealing with designing the electric switchboard and his type-testing. I'm only interested in the thermal and short circuit endurance during the designing part and during the switchboards testing part as well.

Design of presentation electric switchboard for LV
Hlaváč, Jan ; Štefanov, Marek (referee) ; Bátora, Branislav (advisor)
This master’s thesis deals with the design of electric switchgear for low voltage, which will serve for presentation purposes. The switchgear is analogy of the modular system MNS 3.0, which includes the latest equipment of ABB Ltd. that is currently available on the market. Switchgears of this type are widely used in industry primarily for controlling motor units. For this reason, in the switchgear there are located motor starters in various performances, as well as distribution modules. In addition, the switchgear has an automatic transfer switch function in case of failure of one of the power supplies. The complete documentation of the switchgear is processed in the professional software EPLAN Electric P8 with use of the 3D software EPLAN Pro Panel for modelling device compartments. The final part of the thesis is the calculation of the maximum cable lengths that a potential customer can connect to the switchgear. In addition, an analysis of the power and control circuits was carried out for voltage drop calculations, as well as the effect of these voltage drops and capacitance of long control cables on the actuation of contactors.
