Difference between mechanical engineer and mechanic?

From my experience, robotics engineering usually falls under a specialization in either mechanical or electrical engineering depending on what portion you want to focus more on. Robotics from the electrical side focus more heavily on the computer coding and electrical systems where as robotics from the mechanical side might be called Mechatronics at some schools. The main difference is that a robotics engineer is going to focus much more on instrumentation, electronics, and coding of mechanical parts while mechanical engineering gives you an overview of circuits but does not force someone to take that path as part of their education.

I guess in short, mechanical engineering is a more broad major than robotic engineering.
