Hello, I have been trying to set up a physical turtlebot3 following this: https://emanual.robotis.com/docs/en/p.... I've done all the setup, and doen up until 4.SLAM. I noticed that they have a camera there even though it's not being used in SLAM. When I try running the turtlebot3 bringup launch I get no camera topic. When I try launching the turtlebot3_rpicamera node I get errors. Using TB3 Waffle Pi with a Raspberry Pi 3B+ and RPi camera.

The error is: ERROR: cannot launch node of type [raspicam_node/raspicam_node]: cannot locate node of type [raspicam_node] in package [raspicam_node]. Make sure file exists in package path and permission is set to excecutable (chmod +x)

What is the frame supposed to represent? And what is the placement of it in a camera? If you have a big camera (relative to the raspberry camera) like a Logitech C920, where would this frame be defined? I tried defining it as the lens, but this doesn't add up with my measurements. Is the camera_rgb_optical frame behind the lens? I'd imagine it is the image sensor but would like it confirmed because I could not find info about it.
