Course detail

Aventics Pneumobil Racing

FSI-0ZPAcad. year: 2020/2021

The course provides a detailed introduction into basic pneumatic systems and their elements. Students will gain practical experience in control design using the Arduino development board and they will enhance their CAD modelling skills, while implementing the pneumatic system in the vehicle construction. Attention is paid mainly to understanding the function of the pneumatic system and the ability to use the acquired knowledge in designing a new construction. The course integrates the knowledge acquired from the theoretical subjects of the bachelor's study of mechanical engineering.

Aims

Students will gain experience with the development process using an example of a student racing vehicle with a pneumatic drive. They will be able to design a simple pneumatic circuit, including its control using Arduino, and master implementation of the circuit into the vehicle construction.

Specification of controlled education, way of implementation and compensation for absences

Attendance at practicals is required. Absence at two seminars is allowed. Longer absence may be compensated for by special tasks according to instructions of the tutor.
