Construction of an Experimental Vehicle Chassis Using the Lego System
Kratochvíl, Jan ; Porteš, Petr (referee) ; Svída, David (advisor)
This bachelor's thesis deals with the development of an experimental vehicle chassis using LEGO system parts with the aim of creating a platform for development of autonomous driving. To achieve this goal, the experimental vehicle chassis must meet the parameters and characteristics of real automobiles. Therefore, research was conducted to investigate the parameters and examine requirements for steering geometry, wheel bearings, arm structures, hub structures, and other key components of the chassis, as well as the approaches used to address these parameters in official LEGO models. Based on these findings, an initial model was assembled using only LEGO system parts, on which these parameters were evaluated. Limitations of the LEGO system were identified in wheel bearings, arms, and hubs. Subsequently, design modifications were made to these parts, including the use of rolling ball bearings and the production of arms and hubs using 3D printing technology. The second model, constructed using these modified parts, already met the mentioned requirements and approached the chassis of real automobiles.
