IMU noise direct correlation with physics steps/sec

I have found that the IMU noise is directly correlated with the number of physics steps per second. At around 400 steps/sec the IMU is literally unusable. Are there any other settings to reduce this IMU noise?


For reproducing the effect -

  • Load Carter_v1 robot

  • Add IMU sensor

  • Attach a differential controller (set to zero velocities)

  • Print the IMU sensor values through Action graph.
    Now change the physics time steps per second to higher number , say 400 and check the difference in gravity acceleration value.

Please help me, if its a issue with the differential controller or some physics setting needs to be done.
