Duplicate robot (turtlebot3) in gazebo
Hello, I want to copy/paste a robot (turtlebot 3) in gazebo. I launch the command: roslaunch turtlebot3_gazebo turtlebot3_autorace.launch
I'm able to have a second robot but impossible to change in gazebo the topic.
So when I send commands to the robot to move, the 2 robots are moving.
Anyone knows how to change topic directly in gazebo ?
Thanks a lot.
