High Voltage Pulse Generator for Electroporation of Cells
Puczok, Václav ; Martiš, Jan (referee) ; Červinka, Dalibor (advisor)
The main goal of this thesis is to design control board for the experimental electroporation device and to develop control firmware. The first chapter of this work focuses on the electroporation phenomenon itself. Behaviour of the cell model in external electrical field is described there as well as simulation and overview of how electroporation affects living tissue. It also explains the main requirements for parameters of the electroporation pulses as well as need for ECG synchronization. Furthermore, some remarks are given about novel high frequency electroporation method, which involves use of nanosecond bipolar high voltage pulse bursts. The second chapter briefly introduces commercial electroporation device called Nanoknife, including control part, power part, and it's limits. The third chapter consists of introduction of the novel experimental electroporation device developed at BUT. Power part of this device is discussed as well. Next chapter focuses on design of the control board for this device and also on description of the particular schematic parts. There is a control algorithm explanation in the fifth chapter of this thesis followed by the brief manual to machine operation.

Implementation of methods for measurement of rotational speed using cRIO platform
Fábry, Tomáš ; Uher, Miroslav (referee) ; Havlíková, Marie (advisor)
This diploma thesis implements methods for a measurement of rotational speed. It is implemented on the Compact RIO platform from National Instruments. Corresponding SW is implemented using the graphical programming language G in LabView environment. Developed system uses two different sensors – incremental encoder and tacho sensor for measurements of rotational speed. Thesis further analysis and implements a method for an encoder nonlinearity determination and for its on-line correction. For used methods, effects adding errors into the measurements are evaluated and quantified.

Robot Controlled by PIC Microprocessor Unit
Heřman, Petr ; Luža, Radim (referee) ; Rozman, Jaroslav (advisor)
This thesis describes design of a cheap robot. It includes implementation of firmware of low level control unit based on microcontroller PIC. The firmware drives motors, gains sensors data and communicates with the high level control unit. Furthermore the thesis presents realisation of connection to the robotic operation system ROS and its standard structures allowing usage of existing packages for the robot teleoperation and displaying sensor data on the remote computer. The thesis finally reports experiments with the robot. The constructed prototype is the model of the robotic lawn mower, however the whole solution has universal usage.

Energy Self-sufficient Wireless Module for Sensoric Applications
Jacko, Róbert ; Botta, Miroslav (referee) ; Šimek, Milan (advisor)
Masters thesis deals with design and practical implementation of wireless sensor module. The primary requirement for this module is its energy self-sufficiency. In this context, the work gets to the subject of "energy harvesting". Then, in terms of energy requirements, several wireless communication platforms which are favorable for the selected application, are compared. From mentioned technologies was chosen communication platform IQRF. The next parts deals with initial prototype of sensor module, which will be demonstrated as the application of measuring wind direction. This paper describes the hardware and software solution. Followed by a detailed analysis of its properties in terms of energy requirements. Based on the obtained measurements resource parameters are set.

Auxiliary sensorics for unstable balancing vehicle
Solnický, Vojtěch ; Krejčí, Petr (referee) ; Grepl, Robert (advisor)
This thesis continues on successful project of unstable balancing vehicle, which was completed in mechatronics laboratory in last year. The main goal is to supplement vehicle with display device displaying driving conditions. These conditions have to be acquired first from several sensors. Other issues, which are dealt in this thesis, is problem with damage of electronics due to induced voltage in DC motors with permanent magnets, built-in sensor for obtaining information about driver’s presence and logging driving conditions on SD card. In the end there is described implementation of sensors’ output signals verification.

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.
