Looks pretty good, although personally I just like using 1/4" or 3/16" thick for gearboxes and such (more thickness for press fits and counterbores).
Are you planning on tensioning the belt, or are you just going C-C? If you did a slight redesign, you could tension the belt like 192 did for their 2014 gearbox (look it up, pictures on CD).

How did you compute 14 fps using these numbers?

[Team3266Spencer]

I'm getting more like 10.8+/-1.1 FPS (using the no load speed for the CIM, 5310+/-10% RPM).

[wyrzykowskij1]

Oh yes, I apologize. The 14 fps was another calculation that I made. Also, yes, I'm just planning on doing the computed distance from the West Coast Products distance calculator.

Those cut outs in the front and back are SICK.

This is what happens when I miss 1 meeting.

Haha, yeah, I thought so.

These modules are to be mounted in the front of our chassis, giving us 2 total driven wheels on the robot and a total 2 CIM drivetrain.

What ether is asking, is this segway? 😀

Any provision for encoders on this, or just letting programming team guess...

Even for this game, you might want to up to 4. With unlimited non-cim motors, you don't lose anything by moving to 4 cims. Plus, did you compute accleration for that drive? It's going to be pretty bad.

Why did you decide to use belts?
