This was accomplished with 3 follow wheels and a gyro. Two of the follow wheels were used to track the robot moving forward/backward, and one was placed directly under the center of rotation and used to track the robot strafing.

OK that's pretty clear, thanks.
Were the forward/backward follower wheels mounted like
this? And, I assume they were omni, correct?
Did you ever consider, or try, using the data from the follower wheels to compute rotation rate?
