i have been trying to extract rate random walk paramater from the data sheet but couldnt find any clue ... is there any way to do that or what ? how should it be calculated ? thanks !

Practical, answerable questions based on actual problems that you face are always welcome here though, so if you edit your question to fit our community guidelines we can reopen it for you.

  • $\begingroup$ I looked briefly online for "random walk" and for "bias drift" and didn't see anything immediately. I personally wouldn't use an IMU or gyro that doesn't publish that information. As stated in the comment above, I would highly recommend you contact the manufacturer and ask them directly. $\endgroup$

As far as I am aware, figures for random noise coefficients like the Rate Random Walk, or Drifting balance, are not usually included in accelerometer or gyro datasheets (not just the MPU-6050).

Values are normally obtained by creating an Allan Deviation plot as described in this Application Note from Freescale Semiconductor.

I did a brief online search, and I found a paper describing the process for calculating and plotting the Allan deviation function to obtain the Rate Random Walk for an IMU-based attitude sensor using the MPU-6050, which might contain the information you are looking for.
