Hi everyone, i'm almost new in Ros world. (I'm using noetic version) I'm using the launch file 'turtlebot3world' in the package 'turtlebot3simulations' and i'm using the Waffle Robot as robot type. This robot has a depth camera and i have some computational issue about using pointcloud2, so i'd like to set a lower resolution of the depth-camera. I've opened all the file in the package and i can't find a parameter where i can set the resolution of the depth camera. You have any suggestions? Thank you.
