Turtlebot4 Simulator is not working #20

Closed TechExplorer98 closed 6 months ago

TechExplorer98 commented 6 months ago

Robot Model

Turtlebot4 Standard

ROS distro

Humble

Networking Configuration

Simple Discovery

OS

Ubuntu 22.04

Built from source or installed?

Installed

Package version

sudo apt install ros-humble-turtlebot4-simulator

Expected behaviour

The expected behavior is for the Gazebo simulator to launch successfully, displaying the simulation environment with the Turtlebot 4 robot model loaded, without encountering any error messages related to invalid services or busy servers.

Actual behaviour

The actual behavior is encountering a black window in Gazebo, along with an error message indicating that the service [/gazebo/world] is not valid. After a few minutes, another message indicates that the server may be busy downloading resources, advising patience.

Error messages

When I run the simulator with the default setting "ros2 launch turtlebot4_ignition_bringup turtlebot4_ignition.launch.py", I encounter a black window in Gazebo and in the terminal I see the error message: 
Requesting list of world names. Service [/gazebo/world] is not valid."
After a few minutes, I receive the message: 
[ruby $(which ign) gazebo-1] [Dbg] [Gui.cc.333] GUI requesting list of world names. The server may be busy downloading resources. Please be patient.

To Reproduce

  1. Open a terminal window.
  2. Run the command: ros2 launch turtlebot4_ignition_bringup turtlebot4_ignition.launch.py.
  3. Observe the Gazebo simulator window.
  4. Check the terminal for any error messages.
