Distance of travel while using mecanum wheels

If the rollers are set at 45 degrees then in the best case, the robot will strafe at the same rate it moves forward or backwards. Of course there will be some scrubbing losses, so it won't be optimal, but that is true or forward and reverse as well.

^ I can confirm this post. We did our testing in early 2010.

Team 93 is using a small omni drag wheel with encoder that is pressed to the ground with surgical tubing to determine exact distance travelled in autonomous. The gyro is also used to ensure that the robot stays properly aligned with the scoring rack.
