West Coast Drive, WCD

[pwnageNick]

I think everyone has said it right. ALthough two things, the middle wheel doesn't have to be directly driven, and there can be framing on the outside if desired. Our team uses belts and is not directly driving the middle wheel, and we have a sheet metal plate on the inside and outside of the wheel. This is still west coast I believe right? Unless our drive train isn't considered west coast...

For it to be a "True" West Coast Drive, one of the wheels should be direct driven, and the wheels should be cantilevered.

If your drive isn't cantilevered - if it has supports on the outside basically - then it's probably not a WCD. (Unless the support is superficial or for bumper mounting)

Not every single six wheel drop center drivetrain is "West Coast".

However, not every non - "West Coast" drive is bad, by any means. If I used sheetmetal instead of welded tube to build robots, I probably wouldn't cantilever the wheels, because it doesn't really save much material weight.

As others have stated, West Coast Drive System was created by Glen on Team 60 and has been popularized by FRC 254/968/973/1538 etc...

But the best pics of the system:

254 does a great job showcasing the WCD.

Maybe that's why my mentor had me write "Midwest Drive" on our post this year http://www.chiefdelphi.com/forums/sh...ghlight=pwnage

And we made the decision to have sheetmetal plates on the inside and outside for strength, because last year our wheels got bent, and then we made plates for IRI last year with great results. http://pwnage.foxvalleyrobotics.com/..._newrobot.html

Nick, from what I can see, that looks like a standard drive train to me.
