Trouble running Turtlebot3 simulation on ROS Noetic
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: https://emanual.robotis.com/docs/en/p... 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
