ROSbot 2 Pro: Unable to run Gazebo simulation

Hi,

I have ROS2 Foxy and installed Gazebo 11, Navigator2 (and Cartographer) on Dell Alienware laptop with Ubuntu 20.04.
I follow the steps as per the git hub GitHub - husarion/rosbot_description at foxy

I run: ros2 launch rosbot_description navigation_demo_pro.launch.py

The simulator does not run. I see timeout errors in the terminal. The output is pasted below, I hope you can provide guidance for how fix. Thank you, and kind regards,
Jon.

Hi Jon,

To run simulation you should use navigation_demo_sim.launch.py launch file:
ros2 launch rosbot_description navigation_demo_sim.launch.py
If Gazebo doesn’t start in few seconds try exporting gazebo resource path and relaunch the simulation in the same terminal:
export GAZEBO_RESOURCE_PATH=/usr/share/gazebo-11

Regards,
Dawid

Hi Dawid,

Thank you, yes my error, I run the wrong launch file. Now gazebo starts okay, but in Rviz the robot is not shown and no lidar data. I will try to find error in the output and paste it here.

Best regards,
Jon.

Hi,

I could not find any error in the terminal output when running the simulator. We still do not see the robot in Rviz, is there a way to fix it? Thank you.

Best regards,
Jon.

Hi,

Rviz config was missing path to robot model. It is fixed now, you can pull changes from git. You should be able to see ROSbot model in rviz.

Regards,
Dawid

Dawid,
You are brilliant, thank you! I will try it now.
Regards,
Jon.
