Error IMU Compass Data

Post by attrailer2019 »

Hey, I have 2 IMU Beacon. But there is problem on one beacon.
It showed only positive value for X compass data, and negative value for Y compass data.
I have done normalizing the compass output data (using reference in this forum).
But it showed the angle is about 356 deg to 3 deg (only about 6 degree! :( )

Thank you for your support!

Hello,

It looks like external magnetic field - high current electrical cirquits or large metal thing near beacon.
Try to check same far from any metal and electric.
Such troubles with compass are very frequent, so we don't recommend to use it in robots.
