Verastile Sensor-based Experimental Platform
Tydor, Maximilián ; Ing. Vladimír Hubík, Ph.D. (Saab Czech s.r.o.) (referee) ; Šebesta, Jiří (advisor)
This document deals with issues of testing semiconductor inertial sensors like gyroscopes and accelerometers, but also other sensors like magnetometers, inclinometers and others for aviation navigation purposes where strict requirements cover every system. The goal of this thesis is to create modular test platform for testing wide variety of sensors in different combinations under variable circumstances. The development covers mechanical design, electrical design – hardware and also control algorithm – software.

An Extended Model of a MEMS Gyroscope: Design and Identification
Vágner, Martin ; Sopata,, Milan (referee) ; Tůma, Jiří (referee) ; Beneš, Petr (advisor)
The thesis is aimed on measurement and modeling of MEMS gyroscopes based on input-output characteristics. The first part briefs the state of the art. The second part is dedicated to measurement methodology. Critical points and sources of uncertainty are discussed and evaluated using measurements or simulations. The last part shows key characteristics of MEMS gyroscopes based on the survey of a group of different sensor types. The results have revealed significant influence of supply voltage that causes bias drift of the gyroscope and bias drift of the internal temperature sensor. The error can be comparable to temperature drift; however, this effect is not addressed in the literature. The second observed effect is temperature dependency of angle random walk. In the last part, a general model of a MEMS gyroscope is rewritten to reflect observed effects. Moreover, the structure is selected to be easily extendable and the coefficients are expressed to allow a comparison of nominal parameters of different sensors.

Small Rotarz Turntable's Design
Škubal, Karel ; Cejpek, Zdeněk (referee) ; Matoušek, Radomil (advisor)
The aim of this bachelor's thesis is the design, its implementation, and subsequent commissioning of a rotary table. The main goal is to produce a small rotary table that can be used in the robotics laboratory for pick and place applications and possibly for other tasks, for example 3D scanning. The first part of the thesis is focused on description of different types of rotary tables, and individual selected components. Based on this, a table model is then designed and constructed.
