Hello, I am new to ROS, and I wanted to run a SLAM simulation of Turtlebot 3 in ROS Noetic. I was following along this link: but when I ran this command:

export TURTLEBOT3_MODEL=burger
$ roslaunch turtlebot3_gazebo turtlebot3_empty_world.launch

I got this error:

RLException: [turtlebot3_empty_world.launch] is neither a launch file in package [turtlebot3_gazebo] nor is [turtlebot3_gazebo] a launch file name The traceback for the exception was written to the log file

Can anyone help? Thank you

By installing turtlebot3 from source as suggested by the emanual, you will need also to source the package as well after building with catkin_make.

You have two options:

Option 1:

Source after completing catkin_make

echo "source ~/catkin_ws/devel/setup.bash'>>~/.bashrc
source ~/.bashrc


Option 2

Install turtlebot3 from apt. It works smoothly - recommended.

sudo apt install ros-noetic-turtlebot3*
