The aim of the course in mechatronics systems is to provide a focused interdisciplinary theoretical knowledge and practical experience for undergraduate students that encompass fundamental elements from traditional courses in mechanical engineering, production engineering, electronics and computer control engineering. These elements include sensors and measurement theory, digital systems and computation, semiconductor electronics, servoactuators and motion control, machine tools and robotics, altogether focused in deeper understanding of mechatronics aspects of modern manufacturing systems design, i.e., design of CNC machine tools, industrial robots and flexible production lines, based on contemporary numerical and computer control technology.
Theoretical and practical knowledge how to design and select analog and digital circuits, microprocessor-based components, mechanical devices, sensors and actuators, and controls so that the manufacturing equipment, i.e., machine tools, manipulating robots and manufacturing lines achieve desired function. Deep understanding of basic principles of computer based numerical control systems and their application in machine tools, manipulating robots and industrial automation systems design. Microcontroller programming and hardware design skills.
THEORETICAL TEACHING (Syllabus):
Theoretical teaching is organized in four teaching units: 1) Importance and role of mechatronics in modern manufacturing systems design, 2) Digital systems, microprocessors and microcontrollers – basic digital modules, arithmetic logic unit, microprocessor, machine and assembly language, microcontroller architecture and programming, 3) Sensory systems, signal conditioning, measurements and signal processing – working principles and design of sensors for force, displacement and speed measurement, signal conditioning based on semiconductor electronics, fundamentals of digital signal processing, vision sensors and systems, and 4)Electrical servo drives and motion control – stepper and dc motor fundamentals, servo drivers and numerically controlled servo axis, motion control and interpolation, CNC system architecture .
PRACTICAL TEACHING (Syllabus):
Practical training is organized through laboratory exercises and project of mechatronics system design in the field of manufacturing technoloogy.
