Ok i managed to access the terminal via a remote connection.
And think i managed to do all the instructions except for the last one:
When i try to launch the very last command
“husarion@rosbot-78975:~$ roslaunch rosbot_webui demo.launch”
I get this error message:
[demo.launch] is neither a launch file in package [rosbot_webui] nor is [rosbot_webui] a launch file name
I noticed that demo.launch exists in rosbot.webui/launch
Sorry but my linux abilities are null.
