Re: Fabrication
There is really no reason not to CAD. I was our single CADder for our team this year, and I was able to CAD the whole robot before we started building. Again, we had an amazing machine shop, not ridiculous turnarounds, but quicker than we could have done it in. If I had to do it again though, I would recommend CADding a full drive system before the season, preferably 6 wheel, as it is simple, yet robust and maneuverable. We took 2.5 weeks to get a drive CAD out, which was ridiculous. Part of it was that we had a hard time choosing between 6 and 8 wheel, but also, I was just inexperienced(my first year CADding). If they practice, getting a drivetrain CAD done in 2 days can be easily done, and then they will have extra time for manipulators. Furthermore, you will save time by doing this because you don't have to remachine parts.

Programming isn't that hard once you get the hang of it. It has a steep learning curve like math. One day your trying to figure out 1 1, then the next day they throw x and y at you. Once you understand what x and y represent and learn to think in terms of functions, it's as easy as pi. - sciguy125 [more]
