Looks nice! Is it based on the
118 swerve modules (or 221's "
Revolution Modules")?
If you're going to run a swerve with belts, you should look into 1717's 2010 machine:
They might be able to give you some advice on it.
You said this is for an off-season project? Can't wait to see the final version(s)! Remember to post pictures, and good luck with it.
Edit: One more thing. For an off-season project, this probably won't matter, but for a competition robot, if you have the machining capabilities, time, and budget, you should probably replace those shaft collars with snaprings. Those setscrews have a nasty habit of coming loose at the worst possible times, and snaprings take up a heck of a lot less space and weight, too.
