Razor IMU 9DOF: angular change when translating #37

Open chapdelv opened 9 years ago

chapdelv commented 9 years ago

Hi everyone, I'm using RoS Indigo with the 9DoF Razor IMU (SEN-10736).

With DEBUG__NO_DRIFT_CORRECTION set to 'false', the Yaw-Pitch-Roll output does not drift at all. Great!

However, I fixed the IMU on a horizontal translation stage and I was expecting no angular change, but yaw changed by about 15 degrees for a translation of only 20cm.

Is this normal? Is this a calibration issue? I calibrated the gyroscope, the accelerometer and the magnetometer the best I could...but I'm not sure where to go from here.

Best regards, -Vincent
