Enable the Sonars

Hello :smiley:

So, i´m trying to enable the sonars (https://learn.ubiquityrobotics.com/sensors) but i can´t edit the file robot.yaml
I tryed to edit by using the “nano” command, but doesn´t let me save.
Can someone help me?

Thank you very much.

You need to use sudo nano to edit the file. sudo is a linux command that lets you run as the root user, which is required to make most system-level changes like changes in /etc. It is a bit like Run as Administrator on Windows.

It worked.
Thank you very much :smiley:

How do i know that the sonars are working?
