So I am trying to work out how to wire up my custom robots wheels?

I fired up my turtlebot and via rosrun tf view_frames ( I have to be running roslaunch turtlebot_teleop keyboard_teleop.launch)

Frame wheel_left_link exists with parent base_link.
Frame wheel_right_link exists with parent base_link.

However my custom robot has no such frames and I am trying to work out what creates these frames. My Custom frame is running Hector_slam and a Navigation stack

Exception thrown:"odom" passed to lookupTransform argument source_frame does not exist. 
The current list of frames is:
Frame base_frame exists with parent map.
Frame scanmatcher_frame exists with parent map.
Frame laser exists with parent base_frame.

I am just trying to work out whats going on

I have asked this question a few away, the bit i needed to add was. I think I also need the differential package to

<node pkg="robot_state_publisher" type="robot_state_publisher" name="robot_state_publisher"> </node>

This seems to advertises the parts of the robot URDF(joints etc) to RVIZ. The errors went away
