Optimizing the selection of actuators for reconnaissance flying robot
Vítek, Milan ; Gábrlík, Petr (referee) ; Kříž, Vlastimil (advisor)
Purpose of this semestral thesis is to create a set of recommendations for choosing optimal motors, propellers and batteries for multi rotor flying vehicles with respect to flight time and flight dynamics. In this thesis you can find analysis of motor, propeller and battery properties and characteristics and their dependencies. Based on these findings there is a set of rules to choose optimal components and set optimal working point. This thesis also describes the design and implementation of a device used to measure the main characteristics of motors and propellers.

Equipment for long-term test of BLDC controller
Řihák, Roman ; Háze, Jiří (referee) ; Šteffan, Pavel (advisor)
This diploma thesis deals with the design and realization of equipment for long-term testing of the controller of brushless DC motors. In the theoretical part are mentioned principles and explanation of the function of various types of electric motors. The diploma thesis also deals with brushless motors, how they are controlled, types, constructed, etc. At the end of the first chapter there is a mention of thermoelectric phenomena. The second chapter describes the appropriate design of equipment for long-term testing from the block diagram to the construction itself. The third chapter deals with the implementation and function of the entire test system.

Experimental Vehicle for Education
Černík, Adam ; Blaťák, Ondřej (referee) ; Hejtmánek, Petr (advisor)
This master thesis deals with the structural design of an experimental vehicle for educational purposes. Electric motors and their characteristics are described in the introduction of the thesis. Furthermore, the key parameters of the vehicle that influence its dynamics are listed. Based on the specified conditions of the vehicle operation, the main dimension of the vehicle and its conceptual distribution of components were chosen. Subsequently, static and dynamic forces acting on said vehicle were calculated. These forces served as inputs to the FEM (Finite Element Method) strength analysis in Ansys. Last but not least, the results of maximum stresses and safety with respect to fatigue were evaluated. Then the ranges of variable parameters in which they can be set were listed. Finally, the estimated price of the experimental vehicle was calculated.
