Automated compass calibration

asked 2015-06-18 11:50:39 -0600

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?

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.
