Virtual commissioning of multi-axis manipulator
Slavík, Vojtěch ; Radil, Filip (referee) ; Štěpánek, Vojtěch (advisor)
This thesis deals with the design and virtual commissioning of multi-axes manipulator, that will be able to create figures using spherical segments according to a template. In the design, emphasis is placed on the visual appearance and simple operation of the manipulator. The thesis presents the design of the model, methods for inverse kinematics solving, communication of used software and the robot control.

Robotic Arm Exploiting RC Components and Servos
Bobčík, Petr ; Kapinus, Michal (referee) ; Zemčík, Pavel (advisor)
Cílem této práce bylo postavit vlastní robotické rameno, s využitím RC komponent, serv a dodat k němu i vlastní uživatelské rozhraní, které umožní jeho řízení. Součástí řešení bylo také opatřit robotické rameno potřebnou senzoriku, která by umožnila jistou míru autonomnosti. Pro mé řešení jsem se rozhodl upravil již existující design robotického ramene, s pěti stupni volnosti, založeném na krokových motorech. Přidal jsem senzory, jako je akcelerometr, enkodér, měřič proudu, laserové měření vzdálenosti a kameru. Na základě těchto senzorů je robotické rameno schopné detekovat náraz, pozici odpojených motorů, uchopení předmětu uchopovacím mechanizmem nebo měřit vzdálenost předmětu v prostoru za účelem inverzní kinematiky. Vytvořil jsem také jednoduché uživatelské rozhraní, které umožňuje tři typy ovládání, jako je ovládání jednotlivých kloubů samostatně, autonomně s využitím kamery nebo ručním napozicováním.

Inverzní kinematika robota sestrojeného na bázi stavebnice Merkur
ČADA, Jaromír
This Bachelor thesis deals with problematics of inverse kinematics and its application to a robotic arm built from building kit - Merkur Beta 6°. It contains implementation of equations into a program written in Matlab workspace and creation of functions for computing inverse cinematics by FABRIK method. Further it shows, how to set up connection with an Arduino programable platform and control the robotic arm with sent data. The results of this thesis are verified at the end by sample program, which simulates a manipulator.

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.

Robotic arm model design
Kvapil, Jakub ; Dobrovský, Ladislav (referee) ; Hůlka, Tomáš (advisor)
This diploma thesis deals with the design and construction of a robotic arm model. The robotic arm is driven by four stepper motors and two servomotors. Most of the supporting parts are made using 3D printing. The control of the arm is realized by a microcontroller of the Arduino type. The software and the construction are verified on a test task.

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.

System with Model Servos
Švec, Radek ; Materna, Zdeněk (referee) ; Zemčík, Pavel (advisor)
The aim of this thesis was to study the ways of controlling hobby servos, and then to design and create small machine with hobby servos. The created machine is a six-legged walking robot - hexapod with 18 servos for movement. This robot can be remotely controlled using a mobile application for Android. Main control unit of the robot is ESP32 development board. The resulting hexapod is able to walk in all directions and rotate on spot with different walking gaits. It can also change its ground clearance and walking speed. The result of this thesis is a compact walking robot with basic functions, which is suitable for extensions, eg. adding a camera or measuring sensors.
