Design of an application for educational model of a manipulator with three degrees of freedom
Youssef, Daniel ; Křivánek, Václav (referee) ; Klimeš, David (advisor)
Tato práce popisuje další vývoj výukového sériového manipulátoru se třemi stupni volnosti. Práce se zabývá jednoduchou mechanickou úpravou manipulátoru, ale především pak softwarovou částí. Výsledkem je pak hra piškvorky, kdy manipulátor umožňuje hru proti lidskému protějšku. První část práce je věnována zlepšení inicializačního procesu manipulátoru a následně pak i návrhem vhodné polohové regulace. V další části je manipulátor rozšířen o jeden stupeň volnosti. Součástí je i návrh koncového efektoru vhodného pro psaní. Z takto upraveného manipulátoru je sestaven kinematický model vhodný pro real-time řízení. Dalším krokem v práci je návrh samotné aplikace hry piškvorky. Je navržen vhodný hrací algoritmus, včetně detekce a rozpoznání znaků v hracím poli pomocí kamery. Následně je vše implementováno do real-time aplikace, kde komunikaci s uživatelem zajišťuje navržené uživatelské rozhraní.

3D scene reconstruction using Clifford algebras
Hrubý, Jan ; Návrat, Aleš (referee) ; Hrdina, Jaroslav (advisor)
Tato diplomová práce má za cíl seznámit čtenáře se stále ještě relativně novou a neznámou oblastí matematiky, s geometrickou algebrou. Nejdříve jsou uvedeny základní definice a poté jsou studovány vlastnosti obecné geometrické algebry. Další velká část textu se věnuje Konformní geometrické algebře, která je v současnosti jedna z nejvíce zkoumaných a aplikovaných geometrických algeber. Jsou popsány její algebraické a geometrické vlastnosti, konkrétně schopnost reprezentovat určité geometrické objekty jako vektory. Taktéž umožňuje počítat jejich průniky a konformní transformace. Další část textu je zaměřena na aplikace Konformní geometrické algebry, nejdříve k popisu kinematiky robotické ruky a poté v binokulárním viděni.

Robotic structure configuration using MOLECUBES
Vítek, Filip ; Kubela, Tomáš (referee) ; Simeonov, Simeon (advisor)
This master thesis is focused on Modular Self-Reconfigurable Robotic Systems. Their description is made at first and then possibilities of their use are listed. The next chapter concerns Molecubes modular system. The design of similar system where the construction of the individual modules is described follows. The transformations of coordinated systems in the individual modules are described and the calculation of forward kinematics and simulation of inverse kinematics is made at the end of the thesis.

Hexagonal Platform with Servo Control
Korgo, Tomáš ; Maršík, Lukáš (referee) ; Zemčík, Pavel (advisor)
Goal of the thesis is to show the possibilities of using ordinary hobbyist RC servos and means of their control by a computer. For demonstration of the capabilities of servos, we have created Stewart platform which is using hobbyist servos to position the platform. In the thesis there is explained principle of the inner working of a servo, their properties, abilities and also means of their control by a computer. In practical chapters of the thesis there is documented process of designing and implementing of functional Stewart platform along with specific properties of this platform which influence its design. This platform is also reviewed and based on the results we will show technical properties of the platform, advantages and disadvantages of using ordinary hobbyist servos to control the platform. Design of the platform and its documentation is created with respect to intent to make the ddesign, source codes, documentation available to public on wepages focused on aggregating of instructables and tutorials to make usage of outputs possible in practice.

Model and Controlling of Robotic Arm
Bílek, Jiří ; Orság, Filip (referee) ; Rozman, Jaroslav (advisor)
This bachelor's thesis deals with the controlling of Lynx 6 robotic arm using OpenRAVE. I deal with derivation of inverse kinematics of 4DOF robotic arm Lynx 6. The work contains a full description of creation of robotic arms in OpenRAVE XML format. The thesis includes solution of implementation of connecting OpenRAVE program and robotic arm using FITkit. Finally, the work includes consideration of the necessary arrangements for the connection of other robotic arms to the OpenRAVE.

Kinematics of a robotic arm by means of geometric algebras
Křápek, Michal ; Hrdina, Jaroslav (referee) ; Vašík, Petr (advisor)
In this thesis we are dealing with forward and inverse kinematics of a robotic arm using a model of two dimensional space in conformal geometric algebra. Goal of this thesis is a proposal of algorithms for dealing with inverse kinematics problem and their implementaion. Five algorithms were constructed and implemented in python language. One for computing a position of a robotic arm and four for calculating the trajectory of the gripper. In this thesis, the problem was solved using a theorem about orientation of the line segment normal and with the triangle signature. Because of that, the cumputing load was reduced in implementation of the most complex algorithm which is combining the motion of the gripper along a polygonal chain and motion of the gripper along circular trajectory. The benefit of this thesis is a new approach to solving inverse kinematics problem.

Animation of 3D Character in Computer Graphics
Pečenka, Michal ; Štancl, Vít (referee) ; Přibyl, Jaroslav (advisor)
The main goal of this project was to familiarize readers with the techniques used in real-time animation of 3D characters. This work is focused on two types of animation: keyframe animation and skeletal animation. There are described algorithms for software and hardware accelerated model deformations, keyframe interpolations, animation blending, inverse kinematics and ragdoll. The result of this project is a framework, which consists of an animation library, examples demonstrating library functions and tools for export animations from 3D Studio Max and MilkShape 3D.

Creating a 3D human model for teaching sign language
Lička, Tomáš ; Appel, Martin (referee) ; Krejsa, Jiří (advisor)
This thesis deals with developing of a mobile application for learning czech sign language. Individual signs will be shown by 3D model of human. Its movement will be based on videos where lector is demonstrating signs. By analyzing these videos, it will be achieved that the model will perform the same movement as the lector. Final mobile application will be compatible with mobile phones using Android operating system.
