Geometric approach in robotic snake motion control
Vechetová, Jana ; Hrdina, Jaroslav (oponent) ; Vašík, Petr (vedoucí práce)
This thesis deals with the description of controllability of a specific robotic snake named trident snake robot. This robot is classified as a nonholonomic system. The kinematics model is converted into the language of differential geometry and controlled by vector fields and their operation Lie bracket. Approximation of the controlling distribution is also considered. Next, vector field motions are described and also their combinations which provide basic planar surface motions (rotation and translation). Finally, these motions caused by vector fields are simulated in V-REP.

Foundations of geometric control theory
Čulák, Michal ; Hrdina, Jaroslav (oponent) ; Vašík, Petr (vedoucí práce)
This bachelor thesis deals with the description of algorithm for motion planning of trident snake robot. His model is created by means of differential geometry. The controllability of the robot is provided by Lie algebra, generated by elementary vector fields and their Lie bracket. The system is approximated by nilpotent approximation. In this thesis is proposed and described algorithm of motion planning with piecewise constant input. This algorithm is further derived for trident snake robot. Finally, selected motions of trident snake robot are simulated and portrayed in enviroment called MATLAB.

Geometrically controlled snake-like robot model
Shehadeh, Mhd Ali ; Návrat, Aleš (oponent) ; Vašík, Petr (vedoucí práce)
This master’s thesis describes equations of motion for dynamic model of nonholonomic constrained system, namely the trident robotic snakes. The model is studied in the form of Lagrange's equations and D’Alembert’s principle is applied. Actually this thesis is a continuation of the study going at VUT about the simulations of non-holonomic mechanisms, specifically robotic snakes. The kinematics model was well-examined in the work of of Byrtus, Roman and Vechetová, Jana. So here we provide equations of motion and address the motion planning problem regarding dynamics of the trident snake equipped with active joints through basic examples and propose a feedback linearization algorithm.

Geometrické optimální řízení robotického hada
Vechetová, Jana ; Hrdina, Jaroslav (oponent) ; Vašík, Petr (vedoucí práce)
Tato bakalářská práce se zabývá popisem robotického hada tzv. trident snake robota, který z hlediska teorie řízení patří mezi neholonomní systémy. Řiditelnost robotického hada je určena základními vektorovými poli avšak pro zajištění lokální řiditelnosti systému je nutné pomocí operace Lieova závorka vytvořit další řídící vektorová pole. Dále jsou navrženy základní algoritmy pohybu hada v prostoru. V závěru jsou pak některé z pohybů hada simulovány v prostředí V-rep.
