how do I add turtlebot3 to an existing gazebo world?
I'm quite new to using Gazebo and turtlebot. So I have created a new world from scratch inside Gazebo, and would like to launch it with the turtlebot model inside this world. I already have the turtlebot3 packages installed.
How should I go about creating the launch file for me to roslaunch the world with turtlebot inside?
