I have a first year team. Their thoughts are a 6 wheel drive, omni on each end, the center is a sprocket covered with chain and then the high traction rubber over it. They like the slight offset of the center wheel. And that’s not the issue. Issue is how to drive it. Their current thinking is d…

I don’t have much experience with driving multiple wheels with chain, but last year I experimented with powering multiple rollers on my robot with one motor (only difference is that this was vertical, yours I presume is horizontal). I found that the middle roller being powered often skipped and woul…

you can power a 6 wheel drive using only one chain per side (by adding chain tensioners). The chain tensioners allow more chain to be in contact with the link. You can check out 240P’s TP robot reveal which did this: [VEX Turning Point | Team 240P Early Season Reveal: "Low Quality"] Be…

I agree with the application of gears, its the best way to do it (also you have my name)

This thread may also give some info on chain wrap and tensioners. [image] Chain Drive Triangle VEX IQ General Discussion Hi. I’m trying to upgrade our robot to “all-wheel” drive. We already had a chain drive with a 24 tooth middle sized gear on the motor to the smallest …

I like the chain tensioner, I’ll see how I can get that into the conversation. Thanks!

And seeing @Noah10851B post here reminds me that I can prototype in VIQ quicker. I’ve got a two week old team with a mid Nov event, so not a lot of time for them to experiment, but I also don’t want them building a mentor bot.

[image] Noah10851B: What setup of gears would you guys recommend? I would do 84-36-84-36-84, with the 4" wheels on the 84 tooth gears, and 600 rpm motors on the 36 tooth gears, for a speed of 257 rpm on 4" wheels. This is a very nice drive, and is about as compact as you can get from a 3 whee…
