I am able to do everything correctly on my turtlebot except that I can not send it to a certain location. I am able to create a map, save it, load it back up, and localize my robot. When launching the RVIZ, I get this error. I have made sure that DWAPlannerROS is installed by doing this command "sudo apt-get install ros-melodic-teb-local-planner" but my problem still persists.

[FATAL] [1644336371.394594454]: Failed to create the dwa_local_planner/DWAPlannerROS planner, are you sure it is properly registered and that the containing library is built?

"E: Unable to locate package ros-melodic-dwa-local-planner" is the response I get from the terminal. When I do "sudo apt-get install ros-melodic-teb-local-planner" I get that the package is installed and at the newest version. I build the workspace and the problem still persists.

Thank you for trying. It seems strange that ros-melodic-dwa-local-planner is not found. Is it important to eliminate the error and can I use a planner other than DWAPlannerROS? If so, configuring it to use TebLocalPlannerROS as shown below will solve the problem.

<node pkg="move_base" type="move_base" name="move_base">
    ...
    <param name="base_local_planner" value="teb_local_planner/TebLocalPlannerROS" />
    ...
</node>
