The course instruction says to select odom for the fixed frame in Rviz. However, there is no odom option in the fixed frame drop down menu. Can you please fix this?

Hi Janak,

I can see the `odom` in the Fixed Frame drop down. Could you please check again, **making sure the simulation is loaded before that?**
