Development of Test Batteries for Diagnostics of Motor Laterality Manifestation - Link between Cerebellar Dominance and Hand Performance
Musálek, Martin ; Chytráčková, Jitka (advisor) ; Tichý, Jiří (referee) ; Bryden, Pamela (referee)
The aim of this study is to contribute to the standardization of the new diagnostic tools assessing the motor manifestations of laterality in adults and children aged 8 to 10 years, both in terms of determining the theoretical concept and the selection of appropriate items, and the verification of structural hypotheses concerning the design of acceptable models, including the diagnostic quality of individual parts of the test battery. Moreover in this study we try to suggest new approach in assessing of motor laterality manifestation by means of relationship between cerebellar dominance and hand performance. The first part of this thesis deals with the concept of laterality, its manifestations and meaning in non-living systems and living organisms. As a human characteristic, laterality is manifested in a variety of functional and structural asymmetries. This part also discusses ways of diagnosing motor manifestations of laterality and the issue of cerebellar dominance, including its reflection in the form of asymmetry of the extinction physiological syndrome of upper limbs. The second part focuses on the process of the standardization study, the statistical method of structural equation modelling, and the actual design of test battery construction. The last part of this thesis presents the results...

Creating and verifying the targeted compensation program based on the method FMS? (Functional Movement Systems) for clients of Local Gym in České Budějovice
POPELKOVÁ, Eliška
Functional movement screen (FMS) is a tool for rating of selective basic movement patterns and determines pontential risk of injury. The aim was to desing and verify corrective exercises based on the results of FMS for new clients of the Local Gym in České Budějovice. 17 participants attended the screen (12 women and 5 men) in age of 26 to 61 years. All of them underwent the FMS, evaluatuon was conducted according to standardized criteria of FMS. We subsequently designed the corrective excercises, and after three months we retested the clients who regulary exercise twice a week during the lessons in the Local Gym. After comparing the results of the entrance test and retest we can say the most of clients have improved.

Onboard computer for electric scooter
Stříteský, Vladimír ; Burian, František (referee) ; Kříž, Vlastimil (advisor)
The aim of this thesis is clarify construction of onboard computer for electric scooter. There is description of components, from which the electric scooter is built. Within this thesis a computer simulation of accelerating scooter is created. Based on the simulation three possible ways of controlling the electric drive were proposed. Then thesis describe parts from witch control system is composed. Onboard computer and support circuits are described in more detail and explained their functions. Description of the created software is in the final part.

Sensorless velocity control and positions of d.c. low-power brush motor
Svoboda, Jan ; Hanák, Pavel (referee) ; Prajzner, Václav (advisor)
This bachelor's thesis focuses on sensorless control of low load brushed DC motor that is used in the actuators made by the Honeywell company. The first part provides an introduction into motor control and common used methods of speed and position sensing of brushed DC motor. Sensorless method of sensing described in this work is the detection of commutation pulses from the signal of motor current. These pulses are caused by brushes leaping over the commutator bars. Correct evaluation of commutation pulses can provide the information about velocity and position of the motor. This relatively new method of detection of commutation pulses is investigated and arising problems are demonstrated on measured samples of signal. Suitable methods of signal processing are then proposed. Infallibility of these signal processing methods is then proved on the set of signals measured under circumstances of supply voltage and abrasion. Then it is decided which signal processing method that sensorless control system can use is the best.

Positional Motion Control by means of 8bit uP
Janda, Petr ; Holý, Miroslav (referee) ; Matoušek, Radomil (advisor)
This thesis deals with positional control of DC motor Icla D065 of company SIG Positec Automation GmbH with aid of CAN-Bus and CANopen protocol. Individual parts describe general principle and standards of CAN-Bus and international normalized higher-level protocol CANopen for systems control. For control this motor was used microcontroller PIC18F4685 from company Microchip and developmental environment MPLAB® IDE. With used C language was made program for MCU control communication with a motor by support of CANopen protocol and its motion control. The result of this thesis will be used in solution of research project Intelligent Systems in Automation.

Autonomous Control System for Mobile Platform
Kříž, Vlastimil ; Burian, František (referee) ; Žalud, Luděk (advisor)
This work undertake the design of autonomous control system for mobile platform – slot car – for the Freescale Race Challenge 2009. The aim is to draw and implement control system, which will be able to drive the car trough the previously unknow path in the shortest time. In work is described factors that affect runing the car and draw optimal driving style. Then sensors for the car, type of motor control and control unit are chosen. The algorithms for maping the profile and for lap recognition are developed. Next the realization of the systém are descripted.

A traction drive for an electric bike with motor "Heinzmann"
Němec, Petr ; Huták, Petr (referee) ; Vorel, Pavel (advisor)
This work deals with a proposal and construction of a DC/DC converter for a control of a DC motor Heinzmann. The DC/DC converter will be used in an electric drive for a bicycle. The proposal of the DC/DC converter is designed for such engine power to avoid fully any human force to drive - pedaling. The work includes informations about the used motor, progress of proposal and dimensioning of the converter - power circuit and control electronics.
