Multifunction data acquisition, measurement and control device
Trávníček, Ivo ; Vlachý, David (referee) ; Grepl, Robert (advisor)
The thesis deals with and tests the Multifunction data acquisition, measurement and control device. The unit is based on the microcontroller ATmega, which was programmed in the language C. The unit contains functions for the measurement of physical quantify, filtering record, regulation of the dynamic systems and communication with PC. Configuration of the unit is real-time in special software created in the language Matlab or by a terminal. The purpose of the unit is controlling a DC motor by the PID regulator, long-term measurement of temperature or measurement of acceleration by an accelerometer.

Electronic Subsystem of a Small Mobile Robot
Podolan, Luděk ; Jílek, Tomáš (referee) ; Žalud, Luděk (advisor)
The topic of this bachelor thesis is design and construction of a mobile robot with wheeled differential platform. The main goal was to design, implement and test an electronic sub-system for a small mobile robot. Each chapter firstly deals with theoretical aspects of relevant topics and after that describe the process of construction. The thesis shows various ways of construction of the robot with the process of selection of the optimal one. The main controlling part of the robot is the AVR microcontroller placed on the EvB4.3 development board. A simple menu was created on an LCD display for communication between the user and the robot. Battery management is controlled by an analogue to digital converter. The last two chapters focus on encoders and communication between the robot and a proximity sensor. Pictures of the robot are enclosed at the end of the thesis.

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.

Design and Implementation of Small-lot Production Line
Šíl, Petr ; Vdoleček, František (referee) ; Zuth, Daniel (advisor)
This Master's Thesis is focused on the design and control of a small-series production line, for the production of segmetal arches and plastic reductions. It is about the conversion from a semi-automatic line to a fully automatic line. The production line consists of an extruder, a cutting unit, a exhaust unit, three pressing machines and a manipulator. Every single machine has a custom control for which was selected a baseplate with microcontroler ATmega 128 and designed powerful part of inputs and outputs. There is a simple communication between the machines. Appropriate elements were used for conversion of every individual part of the production line. The whole system is programmed with software called AVR Studio4.

Design of construction, control and electronics for unstable balancing vehicle
Zouhar, František ; Krejčí, Petr (referee) ; Grepl, Robert (advisor)
Thesis deals with design of construction, control and electronics for unstable balancing vehicle. The rst part is focused on the determination of requirements for the function and then design and manufacture of structure in line with set requirements, including 3D models and drawings. The second part is devoted to the creation of simulation models of vehicles using the Lagrange equations of the second kind and using SimMechanics. Also PID and LQR regulators are designed, including the advantages and disadvantages of each regulator for this application. The last part is focused on electronics necessary to vehicle operating. They are mainly power electronics (H-bridge, battery charger, switching supply of voltage board). There are also necessary calculations, complete PCB design and a description of the rmware for the this specifc device.

Manipulator control via microcontroller
Šíl, Petr ; Liška, Radovan (referee) ; Zuth, Daniel (advisor)
This bachelor thesis is dedicated to the control of the manipulator by microcontroller. It is a scale model of the manipulator, which will demonstrate the functions of a similar manipulator in the real time practice. The design of the manipulator consists of two parts, the mechanical part and driving part. In each section were chosen suitable parts to fulfil requirements of desired functions. The functionality, simplicity of manufacturing of all sections, the price and simplicity of control were the main criteria during the design of the manipulator. The system utilised ATmega 128 and development environment AVR Studio 4 to control and test microcontroller ATmega128.
