Hello, i have a problem. For ROS Homework at university I have to start from a prodefined package and i have to get the robot to drive predefined points. However when I cant launch to the move_base, nothing happens and 2D Nav Goal also doesnt get the robot to move, how ever when using ros echo on mo…

Hi @woeberinroslol , I just had a fast read of that pdf file. Seems very interesting to be honest! [I also wish that even my university taught me ROS courses.] Anyways, to have move_base node working, you must have a map server and localization (amcl) running. So, if you can tell me what you have…

Hello @girishkumar.kannan , first of all, thank you for the continuous help, it is very helpful and nice of you :slight_smile: So, in the launch file there is already the amcl node, the map server and the move_base node <include file="$(find mir_navigation)/launch/amcl.launch"><arg name="initia…

Hi @woeberinroslol , [image] woeberinroslol: but it doesnt work here on Constructsim, at least as far as i tried Yes, that is true. That is because, I think, this website does not work with MIR robot. I have not seen it in courses I have taken so far. So the best way to get it working would…

Ok, well i do have ROS installed, but it is extremly slow on my laptop and trying to run Gazebo… well it takes a really long time. I will try it with 2D Pose Estimate one more time. Maybe it helps. I already tried publishing to the move_base topic in the webshell, the robot still didn’t move… so …

@girishkumar.kannan Is it easy to just switch the robot? To maybe the turtlebot? Cause that one does exist in the Constructsim.

Hi @woeberinroslol , [image] woeberinroslol: I already tried publishing to the move_base topic in the webshell, the robot still didn’t move I think you might have missed to fill something important. I am guessing that you would have added the pose position and orientation, but you might have…

I used this line of code. It worked in other simulations and it also worked when my collegue ran it

Well, maybe i can make it work, thanks for the help
