Analysis and modeling of sensors and actuators of LEGO Mindstorm
Hanuš, Pavel ; Sova, Václav (referee) ; Grepl, Robert (advisor)
The focus of this thesis is a detailed analysis and modeling of selected sensors and actuators of programmable robotic kit LEGO Mindstorms NXT 2.0. Actuators are represented by servomotors and the selected sensors include a color and an ultrasonic sensor, both available in the basic version of the kit, and a gyro sensor made by HiTechnic. The thesis describes the realization and evaluation of experiments performed for each element resulting in graphical representations of the sensors’ properties, models in Simulink environment representing the respective elements, and datasheets – overviews of parameters and characteristics of the individual sensors and actuators. The detailed analysis of the sensors and servomotors of the kit provides an overview of the possibilities, but also the limitations of the particular elements. This knowledge can be subsequently used for a wide range of possible applications of the kit.

RTEMS Support for Lego NXT
Kačmarik, František ; Bureš, Tomáš (advisor) ; Děcký, Martin (referee)
RTEMS is an open source real-time operating system used in embedded devices across a wide range of processor architectures. Lego Mindstorms NXT is a programmable robotics kit from Lego, which may be used as an educational tool to build a model of an~embedded system with computer-controlled electromechanical parts. The goal of the thesis is to allow development of RTEMS-based applications for Lego Mindstorms NXT platform with the aim of employing the results of the thesis as a runtime platform used in the Embedded and Real-Time Systems Course. The thesis thus identifies a suitable way of porting RTEMS to Lego NXT, provides the corresponding runtime environment and discusses basic means for deployment and debugging of RTEMS application on Lego Mindstorms NXT.

LEGO Mindstorms: Didactic utilization in mathematics with a focus on fractals
Čadek, Jan ; Jančařík, Antonín (advisor) ; Pilous, Derek (referee)
TITLE: LEGO Mindstorms: Didactic utilization in mathematics with a focus on fractals ABSTRACT: The objective of this thesis is to determine whether the teaching of fractal geometry supported by computer and robotic LEGO Mindstorms NXT has its place in the education of primary and secondary schools pupils in the Czech Republic. The theoretical part focuses on key topics and personalities closely connected to fractal geometry problematics. It provides a brief historical overview of the fractal geometry development, its potential use in teaching mathematics (with reference to Turkish curriculum documents), and a description of LEGO Mindstorms NXT which can well serve as a manual for teachers and pupils. The practical part contains instructions for building a robotic turtle as well as a proposal of teaching block aimed to support pupils' algorithmic and geometric thinking including key competencies. Quantitative comparison of the results taken from Turkish studies and evaluation of the project by the author and pupils are a part of the experiment as well. KEYWORDS: LEGO Mindstorms NXT, fractal, programming, Logo, learning by doing, turtle, Papert, L-system, microworlds
