@josh_siegel @Aeden_6007 first off, mad respect your robots are insane. Second thank you so much for the c-channel thing, I actually just added a full c and you made me realize that I could take off the back c-channel without any significant difference. I am definitely going to take off the rubber band things lol, those are from when we were an only mogo bot. I am also going to switch to direct drive so that we loose all the friction in the gears and it spreads the load better. Would you agree with @Mystellianne to keep the chain for center of rotation, or take it off to loose friction and a bit more weight?
Thank you! :) I personally dislike chain on drives in vex due to friction. I would definitely not keep it if the only reason is for your turning center. The only reason I would use chain would be to ensure that the front or back motors are not over-strained due to weight distribution. However, this would only really be worth it if your weight distribution was really terrible (which it doesn't seem to be), or if you had 6+ motors on your drive (which you don't). Even if you do need something like chain, I would use gears, because they are a insane amount lower friction (like 1/10 by my estimate).
Tl;DR Don't use chain, but if you really want to, just use gears instead.
@Mystellianne If you’re invested in a consistent high programming skills, chain is almost completely necessary. I’m not saying you can’t do it without chain (my robot doesn’t have chain and I’ve gotten 84, but only after extensive — we’re talking like 24+ hours of total work), but it will be a massive pain to figure out how the absence of chain affects your center of rotation. When you pick up a mobile gosl, not having chain makes your center shift super far forward, and you need to figure out how that will affect our positioning after each turn. I will also say that if you’re rotating 180 degrees with a mobile goal, not having chained wheels will actually offset you in the x dimension, so you’re not even on the same line you were before. This made things excruciatingly difficult to determine, and left me wishing I had chained my drive just for this occasion.
I really haven't had that many issues with this, but I can see why you might. Out of curiosity, do you use an encoder wheel?
