Steering with chain works great, but I wouldn't say it should be chained. I've seen teams cable. I believe Wilstang did in 2008, I didn't get to see their robot this year up close, but they may have used it again. My team used cog belt this year and it worked just as well as the chain we used the year before, the only thing about belt is that it needs more wrap around its pulleys/sprockets than chain does. I have also seen teams use a linkage, if you look at 141's robot this year it is a good example of this.

Well OK I see what you mean. I just meant to say they needed some sure way that they would stay in sync. Additionally, having said that, we didn't use a physical link to sync our drives. We used an absolute encoder on the steering motors on both sides to "sync" them together. I just didn't want to throw that in because I was asking about a comparison between chains and belts for the dive system and that was a steering system.
