Renovation of historical tram
Rozsypal, Josef ; Černý, Jiří (referee) ; Škopán, Miroslav (advisor)
The aim of this bachelor thesis is to create a methodology of basic works for the renovation of the historic tram and subsequently apply this methodology to the renovation of the historic tram 4MT. The work begins with a general historical overview. Following is a section on pre-renovation and related tasks. The next chapter is about the renovation of vehicles in general. This issue is discussed in more detail in the next chapter, which also describes the process of renovation of individual parts. The last but one chapter deals with the finishing work that follows the renovation. The last part describes the approval process for the vehicle operation with passengers.

Robotic workstation for silicon filling of part of “Valve cartridge”
Černý, Jiří ; Tůma, Zdeněk (referee) ; Knoflíček, Radek (advisor)
This diploma thesis is focused on robotized technological workstation (RTW) for production of “Valve cartridge” product. The production workstation, studied in the diploma thesis, is located at IMI Precision Engineering company and is focused on silicon filling. In the introduction a present workstation is evaluated and a present status of industrial robots and robotized workstation is analyzed. In main part of the thesis two solutions for robotic automation are designed, with respect of assigned parameters. The final solution is chosen by method of multicriteria decisional analysis. Project documentation is created for chosen variant including manipulation work cycle and block diagram of RTW control. The thesis includes calculation of capital return. At the final part of the thesis ergonomics and safety of workstation is analyzed; the risks of robotized technological workstation components are also evaluated. Technologists and quality engineer requirements are taken into account during working on the thesis.

Car Front Axle Driveline Gearbox
Černuško, Lukáš ; Černý, Jiří (referee) ; Kaplan, Zdeněk (advisor)
Goal of the Master Thesis was to design conception of electric vehicle driveline, which is able of torque vectoring between each wheel independently and to design front axle gearbox. The aim was to use up the car on race track and to test dynamic properties of electric vehicle for follow-up development. Due to determined requirements and possible solutions the conception of driveline was designed and basic parameters were defined. The main part of the thesis contains a design of gearbox including strength calculation of gearing, the control of shafts to fatigue and elasticity limiting states, life of selected bearings. Gearbox case was subjected to FEM analysis. The last chapter uses simulation to gain vehicle acceleration. Designed electric driveline is applicable to other sport vehicles after some modifications.

Electric Car Rear Axle Mechanic Driveline Design
Baroš, Eduard ; Černý, Jiří (referee) ; Ramík, Pavel (advisor)
The aim of the diploma thesis is the design of mechanical parts of the rear axle driveline suitable for rebuilding of a given sports car into an electric car. The introductory part briefly explains the physical principles of the drive and contains a brief summary of the current concepts of electric vehicle propulsion. Afterwards, there is a comparison and selection of a suitable concept for a given electric vehicle, determination of the basic vehicle parameters based on the calculation of the longitudinal vehicle dynamics and the gearbox calculation on the basis of which the design is solved. The next part is dedicated to the computational inspection of parts using the finite element method. The final part deals with the placement of the assembly inside the vehicle and the evaluation of the drive mechanism.

Changes of Motivation and Mindset of Generation Y's Employees
Černý, Jiří ; Lideschová,, Dana (referee) ; Kruntorádová, Markéta (advisor)
The diploma thesis examines motivations and attitude of employees in terms of generation mixture. It focuses specifically on Generation Y, which is gradually becoming the main representation element of the generation mix in the workplace. The method com- bines the exploration of qualitative research (in-depth interview applying the techniques of neuro-linguistic programming) with quantitative (questionnaire construction). Based on the findings, with help of metaprogramming (MindSonar) framework, are identified elements of mindsets and values (metaprofiles) of employees of selected company. Then, there are described potentials of development of the company, that can lead to higher company performance.

Manipulation operations with industrial robots
Černý, Jiří ; Kubela, Tomáš (referee) ; Pochylý, Aleš (advisor)
This bachelor’s thesis inquires into problems and current state of robot grippers. Industrial robots used for manipulation, robot grippers, special unit connected to gripping end-effectors and possibilities of its control are mentioned step by step. The accent is primarily put on electric and pneumatic driven grippers. Sample of gripping task with industrial robot and vacuum gripper is solved in the last part of this thesis. The program for control of KUKA robot is output from this gripping task.
