So I am about to finish my Mechanical Engineering degree at Cal State Long Beach. i have found that I really enjoy robotics after making the $50 robot and want to make it a career. However, I am a complete noob. I wanted to apply to Carneggie Melon's Robotics graduate program, although Cal Tech is closest to me because it seems like a more developed program. Assuming I have only taken one basic electronics class and only know MATLAB code, what should be my next step before I even thinking of travelling to Pennsylvania and attempting to get into that program? Obviously I cannot go in as a novice. There are many prereqs I have to take I am sure in order to make efficient use of my time there and not begin in the undergraduate classes. What should I learn on my own? are there lectures online that can get me up to speed?
