Re-design of steering servo-actuators for Car4 experimental robot
Vespalec, Tomáš ; Hadaš, Zdeněk (referee) ; Vejlupek, Josef (advisor)
This thesis deals with the development and design of the wheels mechanism in an experimental vehicle Car4. During this work, we introduce the vehicle axle load calculation, with components and systems, allowing linear and rotational motion, and different design proposals for the application of these systems in the vehicle. The result of this work will be a new mechanism for the wheels of the experimental vehicle Car4.

Strip rolling
Kornherr, Milan ; Suchánek, Miroslav (referee) ; Petruška, Jindřich (advisor)
This bachelor thesis focuses on theoretical analysis of the role of plastic deformation in the process of rolling strips. The work explains progress of stress waveform during straining and lightening. This work also focuses on computing of spring loading and bending moment due to specific curvature of strips. Report at the end of this work includes an illustrative example with executional program.

Mechanical design of locking device of swimming-pool roofing
Machýček, David ; Čudek, Vladimír (referee) ; Paloušek, David (advisor)
This bachelor thesis deals in its background research part with the possibilities of covering or roofing the level of water of a swimming pool. After stating the options for roofing the swimming pool, the efficiency of this roofing is analysed and main advantages of the roofing are found. The constructional items of the swimming pool roofing are also described in the research. At the same time, the most widespread system of the blocking of the swimming pool is analysed and explained. In a part of the thesis, which deals with new solution for covering the swimming pool, individual solutions are proposed first. There are two solutions in this proposal. The first one comes from the idea of a trackage guidance of all the segments, which basically is one of the most widely used systems on today’s market. The second proposal is proposed for a partly trackage guidance of the segments. A suggestion of the partly trackage guidance was chosen for the constructional solutions, for which a 3D digital model has been created and from this model sketches of sets in open and closed state have been generated and adjusted.
