To Reproduce
Provide the steps to reproduce:

1. ros2 launch turtlebot4_ignition_bringup ignition.launch.py

@revan-mando You can use the teleop plugin in Ignition. Set the linear and angular velocities, select "Input from keyboard (WASD)", and make sure to click the play button in the bottom left of the simulator to start the simulation. Then you can drive the robot with the WASD keys.

Note for next time: please create a new issue instead of commenting on a separate issue.
