SCUTTLE Robot – How the Magnetometer Sensor (compass) works

Explanation of the theory behind the magnetometer sensor, and how it must be calibrated. SCUTTLE Project Info: mxet.github.io/SCUTTLE Most magnetometer sensors work the same (including “IMU”s which are just magnetometers coupled to accelerometers and gyros). This example is MPU9250 on the Beaglebone Blue.
