Concept design of a multi-environment mobile robot
 Zezula, Benjamin ; Burian, František (referee) ; Kopečný, Lukáš (advisor)
This thesis presents the design of a multi-enviroment mobile robot that combines the simple principle of movement both in water and on land. In particular, the design of a~four-wheeled vehicle is presented, whose innovation lies in the use of blades on the rear wheels. A suitable type of propulsion system is chosen based on a~study of~different types of~robots. During the research of already functional solutions, great emphasis is put on the advantages and disadvantages of~the different actuators as well as their mathematical and physical analysis. The proposed solution includes the proven design of four differentially controlled wheels for movement on land and the use of~blades on the rear wheels for movement in water. This concept is described in detail using a~mathematical-physical model, on the basis of~which a~working prototype has been developed. The thesis concludes with an experimental verification of~the agreement between the mathematical model and the real prototype. This verification focuses on the motion dynamics and the behaviour of the robot in different environments. The differences observed are attributed to external influences such as the resistance of the gears or the manufacturing tolerances of the individual components.
