2014-01-12 14:20:56 -0500 commented question What causes intermittent gmapping tf cache errors? *update*

Those errors are usually due, if you have not set a right transform_tolerance in your parameter configuration files. and your transform publisher should publish at the rate of 30hz on average for the best result. run rosrun tf tf_monitor to see how often your tf are published specially odom -> base_link

Hello usually computing an odemetry is dependent on the type steering on the robot there are different type of methods for computing velocities from encoder counts first thing I would advice you to do is to read this article and you will then have better starting point. http://rossum.sourceforge.net/papers/DiffSteer/ I hope it was helpful. thanks
