The critical drive train components for a steering chassis. All that's needed now is a welded chassis frame to mount on.

Cool!
You'll be like the 3rd Nor-Cal team to do swerve.
Is it just me or are the vertical miter-gears plastic?

Looks great. Were the side plates CNC'd or waterjetted?

You think that it'd be a problem in the future?

Oh yes - the vertical gears are made of nylon. I don't think mating a steel to a nylon is too uncommon - it's a quieter solution than steel to steel (so I'm told) and doesn't require super-precise positioning. The nylons are also a lot less expensive than their steel counterparts ($4 instead of $30). Still, if the nylons do chew themselves apart, we have a spare set of steel gears.
The parts were CNC'd by Meadows Manufacturing, our local sponsor.
What other Nor-Cal teams are doing swerve?

In this situation, I think that having plastic gears is actually pretty acceptable due to the fact that this is not a game of extreme loads. The wheels would break friction and slip on the surface before any teeth would strip.

Our torque and acceleration control algorithms should prevent sudden direction changes at high-speed.
...should

Re: pic: 1351 Wheel Modules
even if you try and change directions at high speeds, i don't think the friction will allow you to do so, so even if your software fails, the laws of physics should hold

Otherwise, looks great.
