Add to ORKGThe bachelor's thesis is focused on the design solution for a small educational mobile robot, with the possibility of producing most of the parts using 3D printing. The work is divided into research, design and implementation. The research part briefly describes a classification of the robot and the division of its individual subsystems. The research also describes three commercially available kits and the principle of 3D printing. The design part is reflected in the choice of electronics and gradually discusses the individual design solutions, including the design of API. The last part of the implementation presents three modifications based on the design, which are supplemented by notes for printing from various materials
