Hi All, I build environment in gazbo, and run make turtlebot move in it and draw map in rviz.

What I want to do know, is to give turtlebot move commands so it move in real environment and move in gazebo and draw map in Rviz all at the same time ..

What i found is that command go to gazebo or real robot but not the two

here is all [Topics] run (/upfiles/13653369789478456.png)

Thanks

You can run both robots (simulation and real) in their own name spaces.. The robot in gazebo and the real robot can subscribe to the same Twist topic (e.g. /cmd_vel).

If you do this, then both robots will move. You will need to pick one of them to generate the map depending on what it is that you're actually trying to accomplish.

There are no guarantees that the robots will be in the same place when the sequence of Twist messages have been executed due to things like friction and simulation approximations.
