Terminal and Simulation not working any more

I am following the course ROS in 5 days using but I am not able anymore to insert commands via the terminal. There is no reaction and the robot is frozen.

I have followed those steps before and it used to work today it is no working any more.

Please help


Normally this is due toa loss in connection or some process you launched that might have freezer the system.

Can you try and refresh the page? or change to another course an then back again to this one and see if that solves the issue? If not please contact us again
