It seems that linear acceleration units are mm/s. So ~400 and ~500 would represent noise I have compared opencr IMU and Myahrs IMU, results are below. So, I suppose that x and y linear acceleration are fine except on z axis. It is a calibration problem ? ![Screenshot from 2018-01-09 13-00-15|690x241](upload://4H9zS0OMUMGGLMzIBOhrWoK5y57.png) --- [Visit Topic](https://discourse.ros.org/t/tb3-curious-imu-values/3631/2) or reply to this email to respond.
