Hey guys so I'm enrolled in a Mechatronics/Robotics course next semester and it's notorious for being one of the hardest classes that I can take. I'm a little worried about the difficulty of the class, but I think I can get through it haha. Anyway, I was wondering if there were any online lectures or notes or anything that I could take a look at to help me have a little advantage going into the course? Even if I don't really understand much before the class starts, it's always helpful to at least have seen the material. In the last couple weeks of my System Dynamics course last semester, we had some introduction to control systems, block diagrams, and PID stuff (very very basic knowledge). So I guess that's where I stand now. Any suggestions would be great!
