Hi everyone,

We're a 2nd-year team, and up until now we have been using wheels driven by a single gear (last year) or a chain of gears on one side (two motors powering three wheels). We're having a hard time getting the gears to mesh without causing them to strip each other out with lots of metal shavings, or to be too loose if we add some spacers.

We want to switch to a chain-driven system. We have three wheels on each side of the robot and two motors to power them. Should these all be powered by one long chain? Or should one motor run one of the wheels and the other motor run two? What are the pros and cons of each?

Thank you!
