I have tested my kobuki's odom using " rosmsg show nav_msgs/Odometry" AND spin my kobuki 10 times,keeping it's oriention coincident with the begining to my best .

I found that the msg.pose.orientation changed from 0 to 20 degree(i used math tools to compute it). I don't know this result is reasonable or not. I am afraid that it will give a bad impact to gmapping.
