Wow... VERY cool...

OOC, a couple of questions:
1) Are these the 8" Andymark trick wheels, or the 6"?
2) Whose gearboxes are those? That's a sweet package! How are they
switched, and what gear ratios do they provide in high and low?
3) What sprocket pair ratio are you using between the gearbox and wheel?
We been looking at some AM trick wheels ourselves (and ordered a
few for tests... No ship yet, so we're looking at other wheels too).
We were hoping to get away with only a single speed transmission
this year. Four AM or COTS 2-speed transmissions would be very
expensive (worse, EIGHT so we'd have a practice bot too).
But my REAL fear has been that omnis simply wouldn't get us up the
ramp at ALL with a one-speed transmission, without a gear ratio set
that would "crawl" on the ground game.
Now, from what I'm reading, I'm even *more* concerned that
people are saying that they may have to be "tweaked" with some
machining, just to keep them from binding.
How long did it take you to "fix" the wheels?
Based on your experience, any comment on what ratio we'd have
to have to get 8" AM omniwheels to climb it with a full weight
bot, using one regular CIM per wheel? FYI: We ordered the white
rollers (0.9 COF) for our "testing bot", because they wouldn't
mark up the school's and sponsor's floors as much as the black
rubber ones would for demos...
I dunno... Though VERY cool, from what I'm hearing mixing this year's
ramp and AM trickwheels doesn't sound like a promising solution.
Even if they DO arrive, we may want to stick with our "other plan".
Is there someone here with more experience with them know of
a decent gear ratio to make them work with this year's ramp?
