Pros: - Good use of "pros" and "cons"
- Good description of 2, 4, & 6 wheel drive systems
- Good overview of "crab drive" systems
- All aspects are good for new FIRST teams and new members on old FIRST teams to know.
- Pictures are clear and show what is being described well.
Cons: - Tank tread designs were not mentioned. Many FIRST teams still use treads and belts to drive their robots.
- Omni-directional & holonomic designs are not mentioned (as Roger said previously).
- The designer or the FIRST teams who provided the CAD crab module and the CAD gearboxes MUST be recognized. It is inproper to use these pictures without crediting their designers or the team who provided this design.
- In my opinion, it is good form to give credit to the FIRST teams who introduced a certain technology into FIRST. Team 47 introduced us all to "crab drive" and (I believe) 6-wheel drive designs were introduced and made popular by team 25.
- More detail could be given with regard to competitive speeds, torques, and motor power needed to be successful with these drive trains.
Anytime someone puts their effort out for other teams to see and use, it is great to see. You have done a good job here, Chris, and this can be a great document.

I thought about adding that in but is just seemed to clutter the document. I might dedicate a document to the motor selection and the applications of each motor, in a format similar to this document.
and I apologize if you were offended when I did not give credit to the original inventors of the 6 wheel and crab drives. There should be a new site where teams can post their robots and give descriptions, so when FIRST comes around, teams can search a database and find what other teams have done.
