Course abstract

The objective of Course is to give students knowledge in basics of mechatronics. Students learn mechatronic system design, dynamic properties and transmission functions, electrical measuring methods, sensors operating principles and application, acquainted with pneumatic, hydraulic and electric actuators and their application, automatic electric drive fundamentals, electrical machinery types and function, control apparatus and circuits, connection to the electric power grid, programmable logic controller PLC applications and programming.

Learning outcomes and their assessment

• Knowledge - students acquire deep theoretical and practical knowledge in basics of mechatronics. Students obtain theoretical principles of proportional hydraulic, electropneumatic, automatic electric drive systems.
• Skills - ability to creatively use their knowledge in synergistic system analyses and systems thinking and the design of mechatronic products and processes.
• Competence - students are capable of independent critical analysis of use various sensors for control of complex electromechanical systems and ensure the operation of programmable hydraulic or pneumatic systems without any rejections; independently solve technical issues in operation of complex systems.

Requirements for awarding credit points

The course ends with an exam. In order to pass the exam, laboratory work must be defended and tests must be successfully written.

Description of the organization and tasks of students’ independent work

During the independent work the students acquire in depth the topics discussed in the lectures, carry out the necessary calculations for practical tasks and laboratory work.

Criteria for Evaluating Learning Outcomes

The student successfully defends the laboratory works, if he has made the necessary calculations and is able to answer any control question for the job.
