The ATRV 2
The x and y are measured in meters. Theta is measured
in radians. With the robot facing the positive x direction theta
is 0. With the robot facing the positive y direction theta is PI/2.
The x/y position is for a point at the center of the robot. You can see that the robot often turns in place causing theta changes but no x y changes.
The time stamps have been converted to seconds.
Thats about it except to say that the theta changes provided are nearly useless except for when the robot is not turning.
I have been able to fuse this data with the gyro data to get good dead-reckoning estimates.
I gave this sensor type number 10. I hope that doesn't end up
with some conflict.
