Robotic mechanisms control
Mareček, Tomáš ; Hrdina, Jaroslav (referee) ; Vašík, Petr (advisor)
The aim of this thesis is to discuss kinematic models, their properties and control. For this task, we chose a geometric control theory approach. For a predescribed trajectory of the gripper, a straight path in particular, motion planning algorithm for the UR5e robotic arm from Universal Robots is implemented. For the description of motion, the concept of conformal geometric algebra is used. Properties of the algebra objects were thoroughly described and consequently used to propose a model of forward and reverse kinematics of UR5e. Gains and losses of this approach were discussed. The algorithms are implemented in CLUViz 7.0.

Procedural Animation of Human Walk
Mohelník, Petr ; Maršík, Lukáš (referee) ; Polok, Lukáš (advisor)
Animation of human walk is employed in many interactive applications, mostly in computer games. There are many ways to create such animation which differ in compromise among naturalness, control over animation and computing time. This work implements procedural animation which is applicable for walking on uneven terrain. Skeletal animation is used for manipulation with model of human body. Furthermore, inverse kinematics is described and implemented. That allows for adaptation to uneven terrain. It also describes phases of human walk, so we can accurately aproximate them. Proposed solution enables specification of walk using number of parameters and is able to adapt to surrounding terrain. The result should be usable in creation of computer games and should allow for creation of specific animation of human walk without need to create such animation manually.

Modelling, identification and control of robotic manipulator
Šuranský, Michal ; Krejčí, Petr (referee) ; Grepl, Robert (advisor)
Main aim of this master’s thesis is to identify, model and control robotic manipulator with three degrees of freedom. The thesis is a part of major project [17], the aim of which is to create an educational platform. In the thesis the simple PID control and the PID with feedforward compensation control is tested on the model of simple pendulum. In the next part models of DC motors, which are used for construction of the manipulator, are developed and the inverse dynamics model of manipulator is developed. This model is used for feedforward control of the manipulator. In the final part the application was developed, which allows the manipulator to be taught some movements, which can be later on, executed. For the simple control of the application the graphical user interface was programmed.

Robotic Arm with Model Servos
Bobčík, Petr ; Nosko, Svetozár (referee) ; Zemčík, Pavel (advisor)
The main goal of this thesis was to create my own robotic manipulator, which is controlled by its own user interface. I made a robotic arm based on computer Raspberry Pi 3B+ with 5 digital servos and a gripping mechanism in the form of a claw, to which I also attached a laser pointer. The user interface problematics was solved by creating a simple web page (combination of HTML, PHP and JS), which i placed into the Apache 2 web server (installed in Raspberry Pi). I successfully incorporated a way to control the servo one by one and how to control the whole arm with inverse kinematics into the user interface.

Control system design for robotic manipulator
Křivánek, Štěpán ; Andrš, Ondřej (referee) ; Houška, Pavel (advisor)
Main goal of this thesis is to design and realize software for controlling planar robotic manipulator “Mini-swing”. At the beginning, thesis describes general issues of this problem. Research part deals with dividing manipulators in groups by their kinematic configuration. Next part merely outlines usage of National Instruments module “Robotics”. “Mini-swing” manipulator and its kinematic are described in the following part. Design and realization of software for controlling Mini-swing’s ending effector are parsed in next part and at the very end of thesis you can find summarization of accomplished results.

Modelování chůze čtyřnohého robotu
Číž, Adam ; Křivánek, Václav (referee) ; Grepl, Robert (advisor)
This thesis deals with creation of a dynamic model of a walking quadruped robot in MATLAB/Simscape Multibody environment. It describes the process of creation from modelling of the geometry all the way to the gait algorithm assembly. Inverse kinematics was used to create the gait algorithm. The thesis also includes evaluation of the outputs of the model in form of angular velocity and torque time course in the joints of the robot while walking.

6 Axis Manipulator Control
Semrád, Michal ; Chromý, Adam (referee) ; Hynčica, Ondřej (advisor)
This master thesis discusses about designing and realization of a control system for a 6-axis robotic arm. The controlling system consist in a microcontroller LPC1756 with its firmware implemented under the Real-time operating system FreeRTOS and GUI application, running on a PC. The Microcontroller communicates with the PC through a serial line via SLIP protocol. Theoretically, it will deal with an explanation of the important terms, and describes the used robotic arm and its controlling unit. The practical part describes kinematics problems solving, firmware’s realization and GUI application.

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.

Interactive Animation Viewer and Editor
Ducháč, Michal ; Seeman, Michal (referee) ; Pečiva, Jan (advisor)
Since the introduction of high end graphical workstations, computer animation has quickly replaced the traditional means of animation. Nowadays computer animation has many applications e.g. video games, motion picture industry, media, weather forecasting and many others. This master thesis discusses various techniques used to created animations using computers. Keyframing, is the most common approach in computer animation. Borrowing its name from the concept of traditional hand animation, the workflow process remained the same. Basic principles of animation using key-frames are explained and an Interactive Animation Editor solution based on keyframing is proposed and the implementation of this editor is described. Editor uses the Kochanek-Bartels interpolation of values between each key-frame.
