I'm always curious why so many people cite the desire to have a robot that can continue driving through multiple chain/sprocket/etc failures. In the hundreds of matches my teams have competed through, as well as our collaborative partners, I have only ever witnessed two chains break-in both cases it was a sprocket failure.

If your drivetrain is well designed and the chains are properly tensioned, the odds of losing a chain, let alone more than one chain are nearly negligible.

"just say no" to chain tensioners.
i think maybe a 7wd base, lighter than 8wd and 1 wheel cooler than 6wd.
and the "coolness factor" is one of thee most important design features.
