Mechatronic systems merge elements from various technological fields, such as electronics, mechanical, and telecommunication, to create a unique system that performs work more efficiently and precisely. You have probably come across many of those elements. To set your path to being an expert in mechatronics systems, it is vital that you catch a glimpse of the fundamentals of the mechatronics systems. This course will show you the key elements and principles of the major electronics components used in mechatronics. First off, the various definitions of mechatronics and a real-life application of mechatronics are shared. You will learn about the classification of mechatronics products and the historical development of mechatronic systems. In addition, you will be introduced to the major components of a mechatronics system. You will learn about some examples of mechatronic systems such as photocopy machines and their working principles.

Mechatronics also deal with electronics. It is essential to learn about key electronics components that are used in mechatronics. This course will show you the major electronics components and how they operate. Certain laws guide the operation of electrical circuits, and it is essential you know those laws to guide your understanding of mechatronics systems. You will examine the key circuit laws such as Kirchhoff's, Thevenin's, and Norton's laws, which would help you design mechatronics systems. You will also need to understand the characteristics of semiconductor devices as they are critical elements of mechatronics. The course will teach you the rudiments of semiconductor devices. Did you know that the concept of a PN junction is the building block of most semiconductor devices? You will learn the characteristics of a PN junction and how it applies to the operation of diodes and transistors. The course discusses the operational principle of various types of diodes and how to implement diodes in rectifiers. You will be shown the various types of transistors, their characteristics, and working principles. Lastly, the course explains how a bipolar junction transistor can act as a switch in a system and the application of LED-photo transistor in the design of an autonomous robot.

To grasp what mechatronics engineering is all about, you need to start from the basics. Understanding the basics of mechatronics and following the key principles behind its operation will propel you to becoming a specialist in the field of mechatronics engineering. This introductory course will offer you the constituents of mechatronic systems and demonstrate how several systems have been helping us in our daily lives.
