Re: Robot doesn't turn in high gear
Having seen 1647's drivetrain this weekend, I feel obligated to reply.
Their machine has a 6WD configuration with four custom 8x3" wheels with roughtop tread in the middle and rear, and unpowered omniwheels in the front for support.
I can't comment on the ratios they are using, but I WILL say that I noticed a few things when they were running. One, their right gearbox had a big bend in one of the plates (from what I can't guess). I pointed this out to a team member but I don't think they did anything to fix it.
Two, their machine makes a terrible noise when turning. I think that this is a byproduct of the aforementioned dent and possibly grease/chain tension issues.
But all in all, their middle and rear wheels are VERY close together and I really don't see why they would have issues turning. I don't think that changing the motors will make a huge difference - I'm willing to bet that the problem is in the gearbox, greasing, and chain tension.
That said, I loved 1647's machine, and they were a fierce competitor in the playoffs!
