My robot isn't a turtlebot, but it's very close / uses many turtlebot parts.

I'm trying to run the turtlebot calibration routine. On the first step, it rotates 360 degrees. On the second, it only makes it half way, 180 degrees.

Alternativly, I can set odom_angular_scale_correction so that it goes 2 full circles the first step and the other speeds only go one.

Any idea what would cause the lower speed s the higher speeds to be completely off?

[edit] I replaced the create and the power/gyro board without and changes, so it's probably sotware [/edit]

Dropping the update_rate of turtlebot_node to 10 instead of 30 made it perform a lot better in the calibration, but the rotation still seems way off when I actually drive the robot around..
