Hi again,
Over the past few weeks we have refined the original design tutorial document, making a few small changes and one very big one, the addition of a new 50-page sub-section titled "Designing a Drive System", which will walk you through designing a similar drive to our 2013 robot. The new content starts on page 43 and goes to 93. We have made no modifications to the part library, so if you want to follow along as opposed to just reading, please use the link in the first post. As always, questions are welcome.
New and improved design tutorials.
