Re: Contact Area and its Relation to Friction?

Quote:
If the acceleration of the wheels is greater than the acceleration of the robot, wouldn't it determine that they are spinning out?
This is valid if you're moving in a single direction. However, consider from a standstill when you're trying to turn. You'd have to use a gyro to make that determination.

Thursday night another 1885 mentor was under the impression that traction control isn't needed at all. I see the greatest advantage during climbing ramps; he says our "drive straight" code takes care of that since it uses the gyro & encoders to keep us going in a straight line. Not sure how to argue it with him that it's hard to not over-compensate with the gyro technique, but perhaps he's correct and it's enough for the time being. No student is advanced enough in programming yet to be able to take interest in it, but maybe we can throw it in there late in the season.

Low-gear + high-torque situations are the next advantageous place to use it.
