Along with what everyone else said, I suggest taking a look at this Design and CAD guide made by another student on 610. This was written by someone who had no idea how to CAD at the beginning of Grade 9, so it might be quite accessible to newer users.

Designing mechanisms for robots is part of the curriculum of every Grade 9 in the school, so virtually everyone on the team knows how to design a part in SolidWorks and then make it in real life. Due to this, I can confidently say that almost every single student on the team now is better at designing in SolidWorks than our head of Manufacturing/Mechanical than when I was in Grade 9 and it was separate from the CAD division.
Basically, I suggest that the people who build the robot and the people who design it using CAD software learn the other skill eventually, as it makes everything so much easier.
We also have more basic CAD tutorials for the Grade 9 technology course at my school. I'll see if we can post them online.
