CAD/Inventor Drawings for Drivetrains

[twolf]

Does anyone have copies of either Drawing files or Inventor files showing the basic designs for many of the various drivetrains that are used in the FR Competitions? Our team has used the standard kit components and motors as described at the kickoffs to power our robots but we have always been two wheel drive with casters on the front. It has served us well but we want to look for different types of drivetrain options.

We would like to study drawings of some different styles such as the track style among others so we could learn how they work without having to shell out the big bucks to try and design a working system since our budget is not great. We would be willing to pay if we had to. We just want to learn how they work and what components are needed. We can produce detail drawings for components if we had some assembly files such as Inventor drawings.
