Odometry confusion

I'm currently working on a project that requires the use of odometry in order to allow a robot to move autonomously. I'm getting confused as to the best method of going from the raw data given by the wheel encoders to the odom frame in ROS. I've read though the documentation and looked online for any tutorials. However, it still doesn't seem clear.

What would be the step by step process of getting from the raw data to the odom frame?

Hopefully you can help.

I would love to know the answer to that as well.

I suggest starting to look at tf package tf, as well as the odometry part of the navigation stack tutorials odometry_tutorial. That's as much as I know, there are probably people who are far more experienced in this topic.

Have you tried encoders to arduino to robot?

That's not helpful for the majority of the purposes though
