Re: 4WD Turning Difficulties

However, according to

the coefficents of friction in real life happen to be somewhat different from what FIRST tells us they are.

If you run the spreadsheet with the coefficents of friction being .12 in every direction, there is a good chance that your robot will be able to turn

Quite easily, in fact. Although, you should keep in mind that "turn" and "rotate" aren't entirely synonymous. If you attempt to turn with any sort of speed, you're probably going to instead rotate in place while continuing to slide sideways, so drivers of skid steer 'bots are going to have to practice their four wheel drifts to be able to maneuver effectively this year.
