Robotic snake locomotion
Tran, Duc Viet ; Dosoudilová, Monika (referee) ; Hůlka, Tomáš (advisor)
The thesis is focused on creation of a simulation model of a snake-like robot, which is then tested on a demonstration task. First part of the thesis is dedicated to a brief analysis of basic snake locomotion and aplication of acquired knowledge in bionics. After that follows practical part, in which a snake-like robot koncept is developed and the models are then subjected to simple tests in simulation software. Final part of the thesis deals with processing of knowledge and acquired values, from which conclusions are then made.

Geometric approach in robotic snake motion control
Vechetová, Jana ; Hrdina, Jaroslav (referee) ; Vašík, Petr (advisor)
Tato diplomová práce se zabývá popisem řiditelnosti specifického robotického hada, který se nazývá trident snake robot. Tento robot je řazen mezi neholonomní systémy. Model je převeden do jazyka diferenciální geometrie a řízen pomocí vektorových polí a operace na nich zavedené (Lieova závorka). Je také uvažována aproximace řídicí distribuce. Dále jsou formulovány pohyby hada ve směru vektorových polí a jejich kombinace, které zajišťují základní pohyby v prostoru (rotace a translace). Tyto pohyby jsou na závěr simulovány v prostředí V-REP.

Geometric control of a snake-like robot
Jašek, Dominik ; Hrdina, Jaroslav (referee) ; Návrat, Aleš (advisor)
This thesis deals with the nonholonomic mechanics, description of nonholonomic constraints and the control algorithms. In particular it focuses on snake with 4 links. From kinematic equations we derive elementary vector fields, later four more are added thanks to Lie bracket. Using these vector fields we are able to devise an algorithm for controling the snake. Furthermore, the thesis also includes a serpenoid input applicated in the simulation enviroment V-REP.

Snake-like Robots Review and Simulation (Robotičtí hadi: recenze a simulace)
Stolnikova, Anna ; Hůlka, Tomáš (referee) ; Matoušek, Radomil (advisor)
This project has reviewed the snake locomotion and is to design a simulation of a snake-like robot motion as the real biological snake. One of the targets has been to create a simulation of a 6-chained robot, so the device will move flexible. The construction has multiple joints which enable it to have multiple degrees of freedom, giving it the ability to flex. So, the application is very useful in closed space and environment. Based on reviewed kinematic model of a snake motion, the code has been created to present the motion in simulation environment.

Geometric optimal control of a snake robot
Vechetová, Jana ; Hrdina, Jaroslav (referee) ; Vašík, Petr (advisor)
This thesis deals with the description of robotic snake the trident snake robot. From a viewpoint of control theory the robot is classified as a nonholonomic system whose controllability is determined by vector fields. We use the operation Lie bracket to create other necessary control vector fields to ensure local controllability of this system. Then we propose the motion planning algorithm. Finally some of the motions caused by the control vector fields are verified in a simulation environment called V-rep.

Link robots
Vidlák, Marek ; Kubela, Tomáš (referee) ; Simeonov, Simeon (advisor)
Master’s thesis deals with design the link robot and motion simulation. It is divided into four parts. In first part are briefly explained basic information of industrial robots and manipulators, their design and structure. Further it is listed some examples of design industrial robots and manipulators and principle of computation of kinematic chain. On beginning of the second part is performed analysis of configuration link robots, description of their designs and structures, examples of design link robots and their applications. In third part is selected option of design, created mathematical and kinematic model. Then it is designed and described construction of robot. The last section is devoted to simulation of robot’s kinematics, description of simulation softwares and their use for required results.

Software for the simulation of autonomous robot
Šťastný, Martin ; Lang, Stanislav (referee) ; Zuth, Daniel (advisor)
Objective of this bachelor work is to make research of SW, which are used for simulation of autonomous robots. At the beginning I explain general concepts of robotic simulation. And I also explain advantages of usage of robotic simulators. In the first part of my research are described some chosen robotic simulators. The second part of my research compares robotic simulators, which is more suitable for simulations of robotic operations. In the end of my research the most suitable simulator is taken and used for simple robotic demonstration.
