Course detail
Pneumobil Racing
FSI-0ZR Acad. year: 2023/2024 Winter semester
The course provides a detailed introduction into pneumatic systems and their elements. Students will gain practical experience in vehicle design and they will enhance their CAD modelling skills, while working on complex mechanical systems. Attention is paid mainly to understanding the function of the pneumatic system and the ability to use the acquired knowledge in designing a new pneumobil construction. The course guides students through an experience of collaboration on a team project that requires solving several interconnected problems simultaneously. The course integrates the knowledge acquired from the theoretical subjects of the bachelor's and master's study of mechanical engineering.

Entry knowledge
Course prerequisites are:
• familiarity with basic solutions to machine design problems
• familiarity with technical drawing and drafting
• familiarity with CAD modelling
Rules for evaluation and completion of the course
Course credits will be granted to students who will actively participate and submit their partial assignments related to development of the racing vehicle in a form of technical drawings and 3D data during the winter term.
Students are recommended to participate at the lectures. Work on assignments will be monitored and reviewed by leaders of the Pneumobil Racing Teamu Brno during the whole term. Course credits will be granted after submitting the assignments. Submission deadlines will depend on internal schedule of the engineering works and on competition rules of the Aventics Pneumobil Competition.
Aims
Students will gain experience with development process using an example of a student racing vehicle with a pneumatic drive. They will be able to design a vehicle, including a complex pneumatic circuit and its controls. The course will also help to integrate students into the racing team.
• Ability to use and apply the knowledge acquired during the bachelor's and master's study of mechanical engineering.
• Ability to work in a team.
• Knowledge of pneumatic circuits and their components.
• Basic knowledge of system control using Arduino.
• Ability to draft technical drawing documentation considering functionality, usability, manufacturability as well as production costs and deadlines.
