Go to Post If you are playing foozball and your ball bounces back out of the goal, do you expect the table's manufacturer to fix it? No - you groan and keep playing! Nothing's different here. Like Dave said, it's part of the challenge of playing the game. - petek [more]

Yes but factually the other guys are often doing no less. They are sometimes using different terms to do it. Course this means you may have to double check.

FRC11 has been using the Grayhill potentiometer style encoders recently. Too many issues with the end of shaft style. Using the terms used as criteria for this topic we get 128 cycles per revolution.

Depends where in the gearbox/ system. You don't want to flood the Roborio with data.
