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).

with two of these in the robot

What are the other two wheels?


6.46 reduction from the CIM to the gear ... 18 tooth to 36 tooth belt system ... 6 inch wheel

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?
