Do you want to teach yourself? Mechatronics includes related knowledge in three fields: machinery, electronics and computer! To learn machinery well, we must first learn mechanical drawing, mechanical material foundation, mechanical design foundation, mechanical manufacturing foundation and numerical control technology. To learn electronics well, we must first learn the basics of electrical and electronic engineering, mechanical control, PLC and programming technology, and motor drive. To learn computer well, we must learn computer foundation, microcomputer principle, single chip microcomputer and C language. These are just the basic courses of mechatronics. If you want to learn comprehensively, you need to learn more relevant knowledge. There are also "hydraulic and pneumatic transmission" and "electromechanical integration system design". If you want to learn all kinds of drawing and simulation operation software by yourself, you can only choose a certain direction to learn. If you want to learn all the knowledge of mechatronics. Then I think your own brain cells are having a hard time! Therefore, my suggestion is that the landlord should determine his own employment direction and study with choice and purpose.
