Received data from IMU is strange

Postby Will_Drake » Thu Nov 15, 2018 10:40 am

Hello,

I would like to ask you about getting the IMU data from a hedge beacon. I need the IMU fusion data to generate an odometry message in ROS. I have used the ROS package provided by Marvelmind but, when my node gets the data and visualizes the quaternion, it seems quite strange.
Sometimes, the direction is not right, sometimes, the device is moving round itself which is currently still on a table. The behavior is completely random.
I also have calibrated several times the hedge by following the operating manual. Unfortunately, it is not possible to visualize the IMU fusion data on the Marvelmind SDK v5.77 so I am not sure if this a calibration/SW problem or the IMU does not work properly. On the other hand, I have checked the gyro/compass/acceleration data on the SDK and it seems there is no problem with the sensors.

How could I solve this problem? Thanks in advance!
Regards
