The suspension is also a good solution but far more complex to build.

I'm working on fixing the complexity part

I don't know if anybody else asked this but, what is the likelihood of it tearing up the carpet? I know that the drivetrain isn't like ours from this year in the sense that we used tank treads instead of a wheel-based drive, but our drivetrain had a lot of traction, and when combined with the high torque that we had, our treads tore up the carpet a few times, resulting in a few deactivations. We later combatted this by reducing the top speed of the robot so our deceleration wouldn't be as fast, and reducing the amount of torque. I don't know if you've already considered that, but I really like your design and I don't want it to run into trouble should you wind up using it!

I don't think this would neccessarily be an issue for this drivetrain. It isn't using roughtop/grooved/patterned wheels and the contact area on the carpet is much less than a treaded drivetrain (especially treaded drivetrains that have layouts identical to or similar to yours).

Okay cool. I didn't think it would, but any question is worth asking. Especially with a train like this, it seems like a really well thought out idea, and I'd hate to see an unforeseen problem arise from this! Especially after this year, our team had a lot more unforeseen problems than in the past. We've solved these problems on the robot and in our building process, but it's still a really sad thing to see when you think you're gonna do good and something nobody expects shuts you down.

Yeah I know the feeling
