Re: Chain drive vs. cogged belt drive(timing belts)
Were you a high traction pushing robot? If so then you might want to go with #35 chain.
Our team has used #25 chain every year except 2004 and haven't had problems breaking them that I've ever known of (I know we haven't the past 2 years; don't know about before). We've never been a robot with high traction wheels that does a bunch of pushing either though, so I doubt we put as much stress on them as other teams do.
