Tutorials: Which do I need?

Be sure to know the basics of sketching, how to properly constraint sketches so that they aren't overconstrainted and they will adapt properly when/if dimensions are changed. In addition learn how to properly use constraints in assemblies so that pieces don't suddenly do odd things or/ create a model that doesn't allow you to accurately represent your robot. Depending on your manufacturing facilities and what your team uses, the sheetmetal tool is very useful if you use sheetmetal in your robot designs. Also, look at design accelerators if you want to accurately create gears/chain drives that will stand up to any stresses they encounters. Also know how to make correct drawings or the people making the parts may not be too happy. I have some first hand experince with that last point. If you have any specific questions let me know.
