Re: What does it take 6WD/8WD to be successful?

If only 3 wheels are touching the ground when there are supposed to be 4, then the bot will skew one way or the other when put on carpet.
Excellent point, I point you to one of IKE's threads for more information on frame flex and its effect. http://www.chiefdelphi.com/forums/sh...ad.php?t=68307
