Events and notifications - NAO

Created by Herve Franco, Modified on Thu, 28 Oct 2021 at 11:57 AM by Herve Franco

You may receive notifications from NAO system or from an application.

In that case, a small sound is played and the status LEDs remain still white but blink once in a while with a colour indicating the severity of the notification.


Error and Warning notification messages are prefixed by their severity and their ID when they are said, so that you can give them to the customer support to describe more easily your problem.


  • examples:
    1. Warning 801, my battery will soon need charging.
    2. Error 803, my battery is totally empty. I’m shutting down.
    3. Error 722, I can’t move anymore. Some of my motors are too hot in my Right Arm. Please let me rest for a while.
