Are you using amcl or gmmaping?? To see something chose, base_footprint on fixed frame of global options, to see the robot. If you using amcl or gmmaping you must had map on fixed frame.

what robot are you using? try to do the tutorials of turtlebot (but in gazebo, that is a simulator), I learn a lot about navigation (moving robot, planning a path) doing that tutorials.

The mobile base of turtlebot is the kobuki base. Study how turtlebot and kobuki work, and you learn a lot.

in your urdf file the first link in the tree should be named as base link

for example:

<link name="base_link"> <visual> <geometry> <cylinder length="0.01" radius="0.2"/> </geometry> <origin rpy="0 0 0" xyz="0 0 0"/> <material name="yellow"> <color rgba="1 1 1 1"/> </material> </visual> </link>
