M.Sc Electronics

I can't help with course names since I am not at your college or university. Here my advice:
As a graduate in EE, you are already into the robotics at least the theory and practice. What you need is to focus on what I call the mechanics of it: This means circuit design, mechanical considerations, logic circuits, processors, hardware, embedded and loadable software, and so on. There is a specialisation track in robotics according to the National Society of Professional Engineers. So, your thinking of something that is a growing part of engineering thought. Here what you need to do: Find your academic counselor or faculty advisory. Take a list of the curriculum leading to the Masters degree. Ask what you can fit in that will focus your study on robotics and anything related. Your professor will certainly help in helping you understand the work needed to pursue your passion. The academic counselor or advisory will help you map out your course work and give you a game plan. And whatever you do, don't lose sight of your objective. I think this is a critical, growing field to get into. There is some amazing opportunity over the next 5, 10, and 20 years.
