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.

Programming tools for robotic workstations for cold metal deposition
Odehnal, Martin ; Šubrt, Kamil (referee) ; Vetiška, Jan (advisor)
The thesis focuses on the development of software for a robotic workstation designed for the rapid preparation of coating the surface of rotating parts using cold spray metal deposition technology. The cold spray workstation is located in the laboratories of the Institute of Materials Science and Engineering at the Faculty of Mechanical Engineering, Brno University of Technology. The developed application provides support for the institute's staff in experimental activities in this area. The theoretical part of the thesis aims to provide information to the processes associated with virtual commissioning, programming industrial robots, and the basics of cold spray technology. The practical part addresses the specific implementation of the software application and the integration of an external motor to the robotic controller via the PROFINET communication bus.

Virtual commissioning of a robotic welding workplace
Bielik, Ondrej ; Tůma, Zdeněk (referee) ; Vetiška, Jan (advisor)
This bachelor’s thesis deals with the virtual commissioning of a robotic workplace for arc welding. The resource part was devoted to the issue of virtual operation, management of the robotic workplace and the possibilities of programming industrial robots. The following part is focused on the arc welding technology and knowledge from the field of robotic welding. In the practical part, the welding fixture was conceptually designed, and the configuration of robotic cell was created. For the creation of the welding paths of the robot was used the ABB Robot Studio Program. The results of a comparison of technologies of the robotic and the manual welding show that robotic welding of small series production reduces the time required for product production. In the last part, the production of the welding product as a whole and the possibilities of increasing productivity of robotic workplace were discussed.

End effector for manipulation of shape-complex components
Kiselev, Danila ; Pavlík, Jan (referee) ; Vetiška, Jan (advisor)
This bachelor thesis focuses on the conceptual design of a universal end effector for handling shape complex components. The first part of this thesis focuses on a detailed research in the field of end-effectors especially manipulation end-effectors with a detailed description of their subsets. The next section is a system analysis that defines the problem situation and searches for an optimal solution. This is followed by an end effector design section that describes the individual components and the resulting assembly. The component descriptions include technical parameters. To verify functionality, a check calculation of the required gripping force was performed. Based on the results, a working head was selected. The critical moments are checked and compared to the manufacturer's maximum values, confirming the functionality of the proposed concept. At the end of the paper, in the evaluation and discussion chapter, other design options and their advantages and disadvantages in relation to the conceptual option are discussed. 3D models and manufacturing documentation of the individual components and assemblies have been developed.
