Parking Assistant
Mareček, David ; Dluhoš, Ondřej (referee) ; Kubát, David (advisor)
This thesis deals with design and implementation of parking assistant. It introduces the types of sensors for distance measurement and possibilities of using camera system. In implementation there are used ultrasonic sensors, namely rangefinder SRF08 and web cameras. User interface that combines data from individual sensors was designed and implemented. Parking assistant provides function for edge detection, sound and graphics signalization together with automatic night mode.

Mobile robot sensor system
Juhás, Miloš ; Frýza, Tomáš (referee) ; Fedra, Zbyněk (advisor)
In this Bachelors thesis is processed the basic theoretical knowledge needed to design sensory system for a small mobile robot and the sensory system itself is designed. Thesis describes the working principle of tactile, optoelectonic and ultrasound sensors, their basic features, advantages and disadvantages. Next there are processed known prospects of sensors electrical schemes for line following and obstacle detection sensors and commercialy available solutions are briefly described. In the second part there is, based on introduced principles, experimental schemes and measurements, the sensory system itself designed, which is capable of advanced detection abilities and microprocessor conducted data processing. The design is focused on power usage optimisation, control software efficiency and extended universality of designed system. Part of the thesis are libraries of functions required for simple control and sensory system application. In the epilogue there are listed and evaluated the testing results and measured parameters of designed system.

Laboratory Model of the Vortex Speed Indicator
Kazda, Ondřej ; Kolka, Zdeněk (referee) ; Biolková, Viera (advisor)
This work is concerned with posibility of measuring a wind flow by Von Karman vortex sheed structure. The bluff body is situated in the way of air flow propagation and consequentally vortexes will be appeared. Important part of speedmeter design is measurment chamber must allow to vortex sheed propagation. The transient and the reciever are situated vertically to propagation of flow.The Ultrasonic carrier is transmitted and modulated by freqency of vortex sheeding in measurment chamber.Demodulator uses PLL to “focusing“ detection of the ultrasonic beam. This can be indicated like lock and unlock phase loop. From known value of sheed frequency can be directly calculated speed of flow.

Bioloid Comprehensive Kit
Hujík, Miloš ; Veselý, Miloš (referee) ; Žalud, Luděk (advisor)
The goal of this paper is to suggest suitable senzoric subsystem of mobile robot. There are being analyzed robotic kits of different manufacturers. Their advantages and disadvantages in the theoretical way are being explained in this part and also their opportunities of use in the practical way. In the following parts the work is focused on senzoric subsystems of other manufacturers and again are desribed their advantages and disadvantages. On the last part there is shown own concept of senzoric subsystem. HW and SW implementation is described and there are shown testing data of the conception.

Wireless water level sensors
Pospíšil, Jakub ; Číž, Radim (referee) ; Morský, Ondřej (advisor)
The thesis deals with both scheme and its implementation of water-level metering apparatus. This data are send wireless into 500 m distant station. Potential ways of solution are gradually studied and final design suggested. Detailed implementation methods are described in the following section. Ultrasonic sensors are employed for level measurement and controlling element is processor ATmega162, data are transmitted by transceiver RC1280HP. Apparatus is suggested with a view to the lowest power consumption considering it will be supplied only with a accumulator. Solving of accepting station is not a part of the thesis. Functional tested sample is understated in the execution section.

Sensor fusion for detecting and locating people in a room
Vondráček, Jakub ; Dobossy, Barnabás (referee) ; Najman, Jan (advisor)
This diploma thesis deals with the problem of fusion of several sensors for the purpose of detecting and locating people in a room. It is primarily about using measured sensors and implementing them in such a way that their connection creates a system that has obvious advantages compared to more expensive single sensor solutions. In the first part of the work, research is carried out, which presents the basic issues of detection, localization and counting of people in rooms. To be used in the practical part of the work, it is also indicated here which specific sensors can be used to achieve these functions and which control units are suitable for such a system. Finally, it summarizes specific components and software tools, which are further supplemented in the practical part of the work. The rationale for this selection is also included. The second part of the thesis describes the specific design of the resulting system, which can perform the functions of detection, localization and counting of people in the room. This practical proposal is described including all starting points, connections and especially the algorithm that was used for sensor fusion. The entire system is subsequently tested, based on which its functioning is evaluated. In the last section of the thesis, the created system is supplemented with a model of a cover and wall mount.
