Automated compass calibration

asked 2015-06-18 11:50:39 -0500

Is there anything out there done for automated compass calibration for ground moving robots?

For not picking up your robot and rotating it in air for doing it?

Regards

Christian

I have a small script which drives my robot in a circle and calibrates the compass based on the min and max magnetometer readings. It's quite specific to my robot and my custom compass.

I do the drive in a circle open-loop, based entirely on a timer and the assumption that the area around the robot is free.

Do you have multiple axis on the magnetometer or just a single one?

I'm treating my magnetometer as a 2-axis magnetometer.
