Hi , i know that is an already posted problem, but was not able to fix it with ny of the suggestions.

Im using Iheart robot Parts.

1 - Every time I run a Calibration process, I get the information that I have to lower the GYRO_CALIBRATION at about %85 . 2 - I change the file turtlebot.launch . then stop and restart turtlebot service, run AGAIN, and get similar calibration changes need it.

I edited the file gyro.py ( ../src/turtlebotnode/gyro.py To change the DEFAULT 150.00 . I read in other post that depends of the IMU sensor board, that i have to use 150, 250, 300, 500 . IM NOT SURE which one i have to use.
on TURTLEBOTDASHBOARD SENSORS GYRO SENSOR i see the VALUE 500 on Raw Gyro Rate.

so, i modified the file gyro.py with the values 150 to 500 . ? and run the calibration again , with similar results .

any suggestions ?

Im using, Ubuntu Oneiric 11.10 . with ROS ELECTRIC .
