Water level measurement
Seifert, Jiří ; Háze, Jiří (referee) ; Šteffan, Pavel (advisor)
This thesis is dealt with measurement of water level. Measurement is palced in the concrete container under the ground. It was choosen an ultrasonic sensor as an optimal result. The sensor is placed in the safety container IP 65 and it is placed outside into container. The part of water level measurement is the system of the autocalibration. The signal of the sensor is evaluated by ARM microcontroler ESP8266EX. Calculated water level is broadcasted by WiFi modul to server.

Outdoor Robot
Tomášek, Ondřej ; Burian, František (referee) ; Žalud, Luděk (advisor)
This work deals with navigation of the mobile outdoor robots. It is divided in two parts. In the first part, the mobile robots and their control problem is examined. The technical means for navigation and obstacles avoidance are described and the mathematical means for sensor data fusion and optimal position estimation of the robot are outlined. In the second part the hardware of the robot is described and furthermore it deals with description of the practically realized algorithms for obstacles avoidance and robot navigation.

Practical verification of EMAT transducer parameters
Zlámal, Michal ; Havránek, Zdeněk (referee) ; Beneš, Petr (advisor)
The challenge is familiar with EMAT transducers, their basic characteristics and principles of operation. Inclusion of the theoretical knowledge acquired in Semester work 1 is based on the practical measurement of the frequency characteristics of transmitting and receiving part of laboratory made EMAT transducers. Based on the measured results should be followed by an improved design of sensor to achieve higher sensitivity with the appropriate shape of frequency response. For generating of exciting signal is expected to use LabVIEW programme environment. For credible results of the measurements in a broad range is needed to make broadband power amplifier for the transmitting and low-noise broadband amplifier for receiving part of EMAT transducer.

Design and implementation of an ultrasonic sensor for the educational platform
Slabý, Vojtěch ; Bastl, Michal (referee) ; Spáčil, Tomáš (advisor)
Bachelor’s thesis is focused on a design, fabrication and implementation of an ultrasonic sensor module, which will serve for a distance measurement for an education developer shield based. This sensor should be used as an original module which fits in a requested size format. Now is used a sensor HC-SR04 which exceeds size and voltage needed for a module and uses an adapter, which is not rigid. Bachelor’s thesis is focused on a topic of a existing ultrasound principles and its function for ultrasound distance measurement and calculating necessary values. Thesis includes a list of existing solution for designing a monostatic or a bistatic transdcuers sensors. Our module is compared to those solutions and there is also an overview on a two most used methods for a circuit design which controls a transducer. You can find a designed circuits for creating a prototype PCBs, which heart is a microcontroler PIC16F1769. Programming is handled by a PicKit 3, MPLab X IDE in „C“ language. Communication with a Jobst shield is handled by SPI. Result of this thesis is a design, fabrication and use of two prototype PCBs. First PCB is not tied by a size request and serves for a basic circuit testing and basic distance measurement and the second PCB is in a desired size and serves for distance measurement testing and communication via SPI. These prototypes were fabricated and tested in a way to fulfill set task goals.

Linear drive control based on object motion detection
Novotná, Eliška ; Harabiš, Vratislav (referee) ; Sekora, Jiří (advisor)
The diploma thesis deals with motion detection and linear drive control. The diploma thesis is divided into a theoretical part, where the part of ultrasonic sensors and linear actuators, including the types of individual linear actuators, is mainly described and explained. The practical part presents the solution itself, both in terms of hardware and software. This part therefore contains the system design together with the flowcharts and the simplified 3D design of the structure. At the end of the work is given a sample of the final structure.

Altitude control of flying robot
Palacký, Tomáš ; Šembera, Jaroslav (referee) ; Baránek, Radek (advisor)
This bachelor’s thesis deals firstly with design and construction of a device for testing of altitude control algorithms of a flying robot. Secondly with creating and testing of an altitude control algorithm in order to apply findings while creating a copter control system. Provided is a selection and analysis of used hardware and software components – microcontroller AVR ATmega, ultrasonic sensor, motor controller and also communication interfaces IC, USART and SPI. Also design and realization of electrical wiring, circuit board and mechanical structure is being described here. The next section includes creation of software for microcontroller and PC application. The altitude control algorithm is developed using a simulation, furthermore tested and tuned for desired behavior.

Trilobot Upgrade
Polášek, Patrik ; Hrubý, Martin (referee) ; Rozman, Jaroslav (advisor)
The main aim of this work is to create a robot moving on wheels, create communication among all the sensors and microcomputers with the help of the Robot Operating System (ROS). Sensors are mounted on a plastic handle that is printed on 3D printer. The Arduino microcomputer manages low-level signals for reading sensor data and signals to control the engine, the another one and more powerful ODROID-XU4 microcomputer runs the core of ROS and a graphical application that allows controlling robot on the touchscreen.
