[Resolved] Crazyflie 2 IMU issues.
Posted: Thu Feb 26, 2015 8:31 pm
Hi everyone.
Was very excited to receive the Crazyflie 2 again before chinese new year.
Fortunately the board passes POST.
However, settled on a surgically leveled surface, my post POST IMU read outs are pitch -44, roll +150.
Both of these numbers drift gently (<0.1 deg/s) with zero motion or vibration.
Manually rotated, pitch and roll response is 'doughy', settling after motion has ended for perhaps four seconds (>1 deg/s) on top of aforementioned drift.
Pitch and roll response both seem off by a factor of 30-40. This is hard to determine due to the two above effects. For example complete inversion of the board causes a 6-7 degree pitch change.
Yaw drifts downwards slowly but I expect that's a gyroscopic feature. Yaw responds quickly and at expected rate.
I expect that as my board was altered ("repaired") it didn't necessarily receive standard QC. Nevertheless its new and exciting behavior is distinctly unimpressive.
Any advice appreciated.
