robot positioning

If I have MPU-9250 and us accelerometer inside it to count the step move and magnometer to calculate turn of it. Will it estimate the location? Is there any recommend code to do that? I'm not good at this. Thank you!

Not likely. You will need a quite jerky motor action to identify steps. Read the data sheets for the MPU-9250, how fast it can update and deliver new data.
Magnetometer? Links to it.

How accurate does your estimate need to be? And does it need to be repeatable - i.e. several successive moves?

For accurate positioning you really need an external reference system - think about how ships used to use lighthouses before GPS came along.

Why not talk to whoever is providing the steps?

Hi,
Is this a school/college/university project?

You have so many threads going, are they all about robot position location?

It is my university project.
Yes, I try to locate the robot with those 2 method.

No, as you have been told in your other threads, that is impossible with the MPU-9250.

It is time for you to do some actual research and some actual thinking for your university project.

I'm not good at this.

Your university is there to help!

Keep on trying "the impossible" works for squirrels........

Squirrels have a lot more time on their "hands" than humans.

At least helpers. Members have "all the time in the world" unless "urgent"....
