Hexapod Robot Movement Control
Žák, Marek ; Luža, Radim (referee) ; Rozman, Jaroslav (advisor)
This thesis discusses walking robots issues, their classification, management and construction. There are listed the most famous motion algorithms and their graphical representation. Examples of existing walking robots are also mentioned in this thesis. There are also described modifications of hexapod robot, its hardware and software. The robot is controlled through graphical user interface, which displays data from all sensors, visualises positions of all legs and allows the creation of user defined gaits and its simulations.

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.

Remote controled robot unit
Kratochvíl, Robert ; Kosina, Petr (referee) ; Pavlík, Michal (advisor)
Labor is handling of the programming movement functions and construction of the simple robot, a design of double-layer printed circuit boards for its implementation and realizes remote control. Motional functions were tested using the test, hand-soldered, double-layer board implemented on soldery bay of joints and demonstrated on prototype. The movements themselves have been simulated using LEDs, the remaining parts were up to the type of casing the same with a planned final design of the board. Using the prototype we demonstrated complete exact movements. For the control microcontroller was chosen for the board of the robot and controller ATMEGA16, communication takes place through USART bus of this microcontrollers. Programming was carried out in CodeVision and AVR Studio, design of printed circuit boards in the EAGLE.

Hexapod robot
Pizúr, Lukáš ; Háze, Jiří (referee) ; Šteffan, Pavel (advisor)
The aim of this work is the design of a six-foot walking robot, which is controlled by wireless WiFi technology and equipped with a camera that allows to monitor the movement of the robot. The first part describes the possible algorithms for the movement of the six-legged robot, the drive unit and the principle of the servomotor and its control. Different sensor variants that can be used for robot design. Further, possible ways of manufacturing the mechanical structure and materials for its production are outlined. The second part is devoted to the practical realization of the robot. Design of mechanical construction and its production. Design of electronics, robot firmware and control software to control it.

Industrial robots paralell kinematics structures
Pavlica, Jiří ; Zbožínek, Adam (referee) ; Knoflíček, Radek (advisor)
The bachelor thesis deals with the issue and the current state of industrial robots with the parallel cinematics. The first chapter is devoted to an introduction to the issue of parallel kinematic structures and the subchapters deal with definitions of the terms and describe the development of parallel mechanisms. The second chapter is focused on the comparison of serial and parallel kinematics structures. The third chapter deals with the analysis of the construction of parallel kinematics. In the last chapter are described examples of constructions and application of robots with parallel kinematic structure. At the end of the thesis is set down an expected future development of parallel kinematic structures.

Industrial robots with paralell kinematics structures
Šabart, Adam ; Kočiš, Petr (referee) ; Knoflíček, Radek (advisor)
The Bachelor’s thesis is focusing on the problems and the state of the current knowledge in robots having parallel kinematic structure. For better understanding, first of all, the words used are defined, and this definition is followed by the description of the historical developments of parallel kinematics. The subsequent chapter comprises the analysis of structures and the division of parallel mechanisms. This is followed by the basic division of kinematic structures of robots and their comparison. In conclusion attention is paid to the parallel robots utilized in practice and their expected development.

Hydraulic linear drive for paralell kinematics structures of robots
Petruška, Bohumil ; Kubela, Tomáš (referee) ; Knoflíček, Radek (advisor)
This thesis deals with new construction of hydraulic linear drive for paralell kinematics structures of robots. In the first section provides a historical development of robots with this structures. There are also described differences between each machine with this structures and compares them with machines with linear structures. In the second section is made a proposal of hydraulic actuator. Designed actuators are arranged into hexapod. There is also included a proposal of possible solutions to fixing hydraulic actuator to platform and base. This thesis include drawings of selected parts and drawing of a whole set of new designed hydraulic actuator. It is included a block diagram of the hydraulic circuit.

Design of platform simulator
Hlaváček, Pavel ; Macka, Jiří (referee) ; Škopán, Miroslav (advisor)
The diploma thesis deals with an analysis and the strength check of selected componenets of a parallel mechanism containing six degrees of freedom. The device uses crank mechanisms as chain guides. The strength calculation takes advantage of the finite element method. The paper also suggests a design of selected components contributing to a reduction of the maximum stress von misses (according to the HMH condition) causes by the load.
