Course abstract

The objective of the Course is to gain an understanding of the principles of mechatronics, a systemic approach to the design and maintenance of mechatronic systems. Students learn the structure, dynamical properties and transmission functions of mechatronic systems. Students learn the principles of sensor operation and their use for measuring various physical quantities and controlling industrial process automation. Students learn the basics of electronic devices and programmable logic controllers programming.

Learning outcomes and their assessment

Students understands the working principles of mechatronic systems. Gain in-depth knowledge of proportional hydraulic drive, electro-pneumatics and sensor applications, electronics, and PLC applications. The acquired knowledge serves as a basis for working with mechatronic systems. Knowledge is evaluated in tests and laboratory works.
Able to use the acquired knowledge creatively in designing and servicing mechatronic systems. Able to perform system diagnostics and troubleshooting. Assessment - Execution of laboratory work.
Able to use the acquired knowledge creatively in the evaluation and design of the operation of mechatronic systems. Students are able to justify their decisions and integrate the knowledge gained in this and other study courses with work with complex mechatronic systems. Competences is evaluated in tests and laboratory works.

Requirements for awarding credit points

The course ends with a Test. In order to pass the Test, the tests must be successfully written and laboratory works must be defended.

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.
