Thanks, guys.

We have it set up where we can't run two separate chains off the same axle because our robot is almost too wide with no good ways to save any more room, so they have to be in a line. We are using overlapping 6-inch wheels.

We designed it with idler gears so that all the sprockets should have half or more of their teeth on the chain if we use one long chain. But one question is how often do chains break? Ours in on the inside and protected from hits, and the axels are supported on both ends so we hope nothing will bend.

Or if we drive two wheels with one motor and one wheel with the other motor, will that cause problems driving and turning? One end of the robot is heavier than the other by design so we thought putting the one wheel drive on that end. It drove fine with the 2-motor-3-wheel tank gear train and no drop center.

We can test these thing later this week, ourselves, but want to make sure we aren't doing anything too silly.
