turtlebot3 does not have camera?
Hello Helpers, when i run roslaunch turtlebot3gazebo turtlebot3world.launch its working fine but it does not publishing anything related to camera like /camera/depth/camera_info or /camera/depth/image_raw (when i see in rostopic list).
So question is, what is wrong with me. can i add camera in my turtlebot3 if yes so please share the process, it will be highly appreciated.
Thank you

Maybe it's late to answer, but i couldn't find camera node too. But then i found camera as a topic with this command:
rostopic list
So i start to find which node publishes this camera topic. And logically it must be gazebo cause gazebo is producing the environment for us.
rosnode info /gazebo
As output you will see publications, subscriptions, services etc. as a publication there is a camera topic.
So if you want to find and use camera i think you should use it from gazebo node

The normal urdf file in turtlebot3_world.launch
is oen without a camera.
Have a look at turtlebot3_autorace.launch
or simply change the model argument in turtlebot3_world.launch
eg:
roslaunch turtlebot3_gazebo turtlebot3_world.launch model:=burger_for_autorace
