I can find you hours upon hours upon hours of traction wheels playing effective defense or offense around mecanum drives. There's video of some smart defense and plays by mecanum drives too, but certainly not entirely because of their wheels. If you're asking me to find a video of a bad frame being smashed to pieces by a traction drive, what does that have to do with anything? The strength of your frame isn't determined by your wheels.

traction: they have used it for so long and thats what they are used to and have plenty of spare parts for
I'm sure that's why some teams use traction drives, but really? Are you really trying to say that legions of good teams in FRC just make drivetrain decisions because they've never done anything differently? That's pretty awful engineering.

octanum sounds like a good offseason project but a waste of weight and expenses... the key to mecanum is speed... gear it high (stock toughbox nano will do) and go... you can have a scale-down button if it is too quick by itself.
If you gear it high, how are you fundamentally different from a traction drive? High gearing implies traversing long distances. When you're doing that, a traction drive would certainly be able to go slightly diagonally to counteract losing strafing ability.

Now look, this was supposed to be a lighthearted thread where both sides would laugh about a prank everybody enjoyed...
