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.

Datalogger with parallel data logging
Havlena, Marek ; Minář, Petr (referee) ; Zuth, Daniel (advisor)
This Bachelor's thesis is dedicated to the design and implementation of the Datalogger module, which stores data in two different memory storages. First memory storage is solved by using an SD card and the second is the internal EEPROM memory of the microcontroller. It also deals with data synchronization between these memory storages. Communication between the cards is through the SPI bus and communication with the module is provided by a serial interface designed by USB transmitter (UART).

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.
