The amount of space for equipment vs. classroom probably depends on how much equipment you can afford, and what kind of technologies you will be working with. If you are concentrating on design for CNC machines, then you'll need plenty of room for the machines and computers. If you are concentrating more on design that uses manual machining operations, then you might get by with 20 x 30 for the shop area, roughly 1/2 to 2/3 for machines and 1/3 to 1/2 for workbench/storage. A shop gets small in a hurry when you start filling it up with machines! A rollup garage type door would be really nice, both for getting machines in and crates out.

Put lots of electrical outlets in the shop, there never seem to be enough. Be sure to run 220 or possibly 3 phase to the equipment area.

Compressed air may or may not be a good idea. Think about what your machines need, if you will not be using equipment that needs it, then it might be a safer shop without compressed air.

I also like the safety/non-safety glasses area, being able to take a break in the classroom every now and then is nice.

I don't think you'll have enough room for a dedicated mock pit area, or robot corral, but you could design the classroom area as a multi-purpose room, perhaps get tables and chairs that fold up compactly, and some type of moveable divider system to give you temporary corral.
