Post good resources for learning how to design mechanical systems, and/or what your degree covered for anyone who studied mechanical engineering.

I've already been through a CS degree so I know how to self learn STEM shit. I have a decent grasp on multilinear algebra and calc. I haven't done much physics, but I'm only concerned with the physics used in MechE which I presume doesn't go much further than newtonian mechanics and elementary thermo. Anyways, I'm really looking to learn how to design mechanical systems primarily for robotics. I already have a decent understanding of mechatronics so I'm really just looking for the last piece of the puzzle here.
