Be afraid... Be VERY Afraid

is it a swerve module with some sort of shifting wheel assembly? are you going for smaller wheels for when you want more torque and less speed and then bigger wheels for more speed or something like that?

great job on the cad!
can't wait to see what it actually is
does look very menacing!

Correct me if I'm wrong, but smaller wheels don't give you more torque. They do reduce the distance traveled per rotation but there should be same amount of rotational force on the shaft, regardless of wheel size. While they are probably geared differently, there's no advantage that I can see of having different sized wheels for different speeds or more torque. A shifter would accomplish that without the need for an extra wheel.

Actually, new question (I'm sure you can answer this without giving away what this magnificent machine is) - Is the smaller wheel powered?

Yes, both wheels are simultaneously powered

Oh good, now I don't feel so bad at looking at the CAD model (Which looks beautiful, by the way) and being absolutely dumbfounded about what it actually is. While the guess that it is a shifting wheel, as it stands right now it doesn't appear that either of the wheels are actuated (Might just be the angle).

I'm intrigued as to how this would be a revolutionary design both in and outside of FIRST. Perhaps once light is shed on its design I will be able to figure out how revolutionary it is.

Thank you for the CAD compliment! And yes, it's just the angle. Both wheels are actuated as a matter of fact.

Could we get a top down view?

Wait, the slot near the big wheel looks the same size as the other side. Can this thing flip 180 degrees?

Smaller wheels will give you more torque. Think of a wheel like a pinion on a rack, except there is no teeth. IF you reduce the pinion size you get more torque but less speed.

Is this the completed assembly? Another guess of mine is that in addition to having different speeds, based on which wheel is touching the ground, you could have different wheel bases. So basically, in one orientation(likely the one with the higher speed) you have a smaller wheel base, therfore you can turn easily. On the other hand, when the other wheel is touching the ground(likely the lower speed), you will have a larger wheel base and therefor it will be harder for you opponents to turn you.

This is how I usually think of it.

Anyways, is there a reason you are using belts and not gears for this? Is it for a more quiet operation?

Are the wheels of different material? Is one grippy for more traction but one slippery for ease of turning? Maybe this isn't a swerve, but a fixed unit and you have the slippery wheels to ease turning a 4-wheel long bot. But I doubt its as simple as this
