costmap not appearing for actual robot, but appears for gazebo simulations for turtlebot3 navigation [closed]

edit

Currently, I am working through the turltebot tutorial and I am trying to adapt it for autonomous navigation. Currently, while testing the tutorial packages, the simulations work fine, but when I run the bringup and try on the actual robot, the code doesn't want to work as intended. In rviz I get: No transform from [object] to [map] sometimes. I was wondering, is there anything I need to change between the simulations and the actual code as it doesn't seem to work. Also, I am aiming for this to work with a dynamic map such as the robot can navigate to the goal without a saved map, creating the map as it navigates using SLAM. Any advice?

Thanks
