Problems with navigation stack ..

edit

Dear ROS developers,

I'm figuring many problems when running navigation stack in Hydro and Ubuntu 12.04. In fact, after fixing the current position and giving a goal to reach using RVIZ, I see in the map a red line showing the planned trajectory but the robot don't follows this line and starts rotating ...

I'm using Rosserial and arduino mega to communicate with motors ..

Any suggestion or help will be appreciated !

Thanks in adavance. Regards.
