Data glove: VRML visualization and design of electronic circuits
Štěpánek, Jan ; Bezdíček, Milan (referee) ; Grepl, Robert (advisor)
This work deals with designing and assembly of electronics of a data glove and creation of a hand visualization which projects a real-time state of user’s hand. Realization was a team effort of two students. The division of tasks is described in the chapter called Stanovení cílů práce. The beginning of the work is dedicated to a background research in the field of data gloves. Next chapters describe creation of the model of virtual hand. This model‘s task is to project real-time state of user’s hand based on data received from the flexure sensors and MEMS accelerometer. Communication with PC is realized through BlueTooth serial port virtualization. Mathematical model created in Matlab processes data received from the glove and calculates the values of the positions of the individual parts of hand. Matlab also served for development of a graphical user interface which enables the user to utilize the glove.

Design and implementation of complementary sensory system for experimental car
Šimurda, Matěj ; Krejčí, Petr (referee) ; Grepl, Robert (advisor)
This thesis deals with design and implementation of complementary sensory system for experimental car. It deals with temperature sensors, sensors of dumper position and collision avoidance sensors. The first part is focused on background research of temperature sensors and distance sensors. The individual parts of sensory system are described in the following chapters. All chapters contain theoretical design of system as well as final implementation and summary. The description of model for simulating heat transmission in electromotor is described in the chapter of temperature sensory system as well as preliminary measurement of heating-up the winding and shield for establishing the unknown constants in model. The making of functional code to reach the successful communication between the sensor and dsPIC microcontroller via I2C interface is also described. This interface was used for all sensors of the system. The flex sensors are used in the chapter of dumper position sensors. Variable voltage on it is converted by ADC into discrete signal and sent to the control unit. The cheap IR distance sensors are used in the chapter of collision avoidance sensors. Output voltage is also converted by ADC.
