Is this normal?

My bridge is running; however, I can not see the topic.
My Robot is spinning slowly without any command.
I can receive TF tree.


Hello @bluebird ,

What command are you using to start the bridge? Also, has the bridge never worked, or has it stopped working suddenly? It might happen that the bridge dies when there are errors in the navigation nodes. In this case, it should be enough with restarting the bridge.

The bridge is broken!

Even the bridge seems work, it cannot pass the message to Gazebo. I cannot command with ’ teleop_keyboard.’

How can I reboot my Virtual Machine?
