Design of control unit for an autonomous vehicle
Vobruba, Martin ; Formánek, Martin (referee) ; Adámek, Roman (advisor)
The topic of this bachelor thesis is designing control unit for an autonomous vehicle. The new ECU replaces the old one which was without access to the source code, so its functionality couldn’t be modified. The purpose of the ECU is to receive a message from the control computer, process it, control the actuators according to the orders and inform the computer about their current state. The first part of the thesis is research of the vehicle kinematics and CAN bus. The practical part focuses on the analysis of the previous ECU which is crucial to its replacement. It is followed by the firmware and hardware design. The last practical part of the thesis is the testing of the new ECU’s functionality.

Electro mechanical actuator design
Hlavnička, Matyáš ; Koštial, Rostislav (referee) ; Juračka, Jaroslav (advisor)
This bachelor thesis focuses on the structural design of an electromechanical actuator with redundancy of motion screws based on the required parameters using available components on the market. The actuator components were selected to be able to transmit static loads of 2 kN and dynamic loads of up to 400 N. The sub-objectives were to describe the types of hydraulic and electric aircraft actuators in the context of more electric aircraft.

Test Equipment for Solder Joint Strength Measuring
Čechák, Ondřej ; Špinka, Jiří (referee) ; Starý, Jiří (advisor)
This master thesis introduces the problematics of the tensile strength of soldered joints and the correlative mathematical formulas and the use of mentioned problematics in the technology of die shear/pull machines designed for the solder joint tensile strength measurement. It explains the importance and reasons for the use of this technology. The emphasis is then laid on the design and construction innovations of the current laboratory manual shear/pull measuring machine, its semi-automation and the possibility of utilizing the innovated system in a laboratory class of a subject on FEEC BUT.

Modelling of linear power drive with DC motor for control purposes
Vrbka, Michal ; Březina, Lukáš (referee) ; Houška, Pavel (advisor)
In my diploma thesis, I developed the model of a linear actuator for the control purposes. The first part summarizes the literature research of currently available linear actuator systems. The work further describes some of the capabilities of the simulation environment Matlab which was used for the creation of the computer model of linear actuators. In the last part, this theoretical model is compared with already available physical model of the system.

Design of linear ball screw actuator for higher axial load
Turek, Lukáš ; Klapka, Milan (referee) ; Koutný, Daniel (advisor)
This bachelor thesis solves the construction of a servomotor with a moving screw for higher axial loads. The aim was to design a servo actuator for an axial load of 25 kN, which can be clamped from both sides. The partial goals were to develop an overview of electro-mechanical servo actuators, to analyze the force ratios, load capacity and service life of the current actuator solution. Further process the calculation and design of the actuator, including drawing documentation of selected components for higher axial loads.

AC electric linear drive for paralell kinematics structures of robots
Nejedlý, Petr ; Pavlík, Jan (referee) ; Knoflíček, Radek (advisor)
Design of linear actuator for parallel kinematic structure is described in this master´s thesis. The parallel kinematic structure is described in the first part. Open kinematics structure and close kinematics structure are compared. Their benefits and disadvantages are also mentioned. Construction of some parallel robots is illustrated. Linear actuators of different company are described. Mechanical parameters and construction of linear actuator are compared. Design of linear actuator is described in practical part of master´s thesis. A few variation of linear actuator are introduced. Individual variants are evaluated by Multicriteria Decisional Analysis and a final conception is selected. Final conception of linear actuator is elaborated. Reasons for selection of every part of linear actuator are given and basic mechanical calculation design part is made. FEA analysis of the structural part of linear actuator is made. Design of linear actuator is evaluated in the final part.
