Quick question about 6wd!

I can pretty much push you where ever I want and you can't do much to stop me.

This works on 'normal' six wheel drive bots that have a dropped center as well. The way I look at it is this: If you build your robot so it's easy for you to turn, then it will be easy for others to turn you, too!

In 2007 our robot was the standard 6wd, dropped 1/8" center, 6" wheel drive train. When people played defense on us, they could turn us no problem.

In 2006, the best defensive bot I've ever seen (1662!) had four 8"x2" wheels, all at the corners. Their robot had quite a bit of trouble turning, but when they wanted to stay in place, they stayed in place.


It's just another one of those tradeoffs...

That is true but i have found that the little bit of resistance that you have on the corners can go a long way. We had 8"x2" wheels on our bot in '07 and defenders had a hard time pushing us, but when it came time to turn it was nearly impossible, especially in high gear. I guess there is just a fine line between good turning and strength against defence. Granted alot has to do with the game as to how much defence will be played and how maneuverable you want to be.
