Hi!

I am totally newbie to the ROS world. I am working on my final year project that involves indoor mapping via quadcopter. I had a very hard time starting with ROS.

Now that I have installed ROS Noetic successfully, I am facing an issue while launching a gazebo file. I am following the instructions in this repo on GitHub: https://github.com/lemontyc/my_robot

I have cloned the repo inside the src folder, and have installed the packages, but when I run this command: roslaunch my_robot world. launch

It says: RLException: [myrobot] is neither a launch file in package [gazeboros] nor is [gazebo_ros] a launch file name The traceback for the exception was written to the log file

There might be a simple fix, but since I am new I know nothing. Please help!
