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.

Modeling and identification of medieval catapult
Štupák, Jakub ; Křivánek, Václav (referee) ; Grepl, Robert (advisor)
This thesis is about modelling and optimalization of medieval trebuchet and few of his simplified variants. First part contains information about similar siege engines, description of working principles of medieval trebuchets and his parameters used in history. In practical part have been created four modes of trebuchet with different level of simplification. Subsequently have been calculated range and efficiency of this system in dependence on his parameters. These parameters have been optimized to obtain maximum range, and obtained results have been compared between models. Lastly real, scaled model of trebuchet have been made, and his motion have been compared with motion of computer-based model. With this computer-based model have been also obtained optimal parameters of scaled trebuchet.

Modelování chodicích robotů s pasivní dynamikou
Cvik, Dominik ; Hrabec, Jakub (referee) ; Grepl, Robert (advisor)
The presented bachelor's thesis deals with the creation of a model for a passive dynamic walking robot. The research part of the thesis describes the classification of two-dimensional robot designs with passive dynamics, along with a description of selected existing physical implementations of such designs. Equations of motion for the synthetic wheel design are derived analytically in the next chapter. These derived equations of motion are used to obtain initial values of variables, which will later be substituted in the simulation of the same model in Simscape Multibody. These obtained initial values are also substituted into the solution of the equations of motion. A comparison of the state variable time progressions obtained from the simulation and the analytical calculation shows a high agreement between these approaches, with only minor deviations, which are explained by the simplifying assumptions used in the analytical calculation.

Modelování a simulace jednonohého acrobatického robotu
Tomášek, Jiří ; Rajchl, Matej (referee) ; Grepl, Robert (advisor)
The thesis focuses on the development of a dynamic model of a single-legged robot with a specific emphasis on jumping. The model is created using MATLAB/SimScape Mul- tibody environment. It covers the process from robot design selection to the design of the jumping algorithm and its optimization. The thesis also includes an evaluation of the model outputs, such as torque and angular velocity profiles in the actuators, as well as the jump height.
