Automation involves many disciplines, whether it is mechanical or electrical, automation involves motors, mechanisms, analog electrical, digital, single-chip, programming, algorithms, control theory, finite element analysis, etc., from traditional industrial control to PLC, from ordinary servo The application to CNC machine tools, from robots to artificial intelligence, from embedded operating systems to dedicated systems, involves too many fields, and in this large field, no matter what direction we develop in, it is not a deviation. This is the advantage of automation. So, as long as you want to work hard, you can become a bull in any direction!
