  • Robotino3 frimware update

    I updated my Robotino3 with the latest Robotino4 firmware image.
    Since then, the controller shuts off in about 30 seconds after I disconnect the VGA display from the VGA connector on the Robotino.
    Is it a known issue?
    What can I do?
    Can I and should I revert to the Robotino3 frimware image?

    Sorry for the slip ("frimware")... maybe it's just how I feel about Robotino! ("frime" in french means "show off")...

    I reverted my Robotino to version "robotino3-3.1.5".
    I can now unplug the VGA display without the Robotino shutting itself off, but I don't have the REST-API any more.

    I got the software from this page:

    By looking closer to the file names, I noticed that all Robotino3 images over 3.1.6 are named "robotino4-something"...
    Does this mean that all images over 4.0 are in fact Robotino4 images?

    Here's what I did next:

    1. download 4.0.0 image (robotino4-4.0.0.fsa)
    2. install 4.0.0 image on the Robotino

    Noticed no change in regard to version 3.1.5.
    Ubuntu version is still 16.04 (and not 18.04 as indicated on the wiki page).
    However, though I can connect to the Robotino web interface at, the request to '' (as for many other requests to the rest-api) returns nothing at all (not even "404 not found")...
    This is as if version 4.0.0 has an incomplete rest-api...
    When I unplug the display from the VGA connector, the Robotino don't shut off by itself.

    Then, when I tried to download the 4.0.1 image from the wiki page, I got this:
    "Not Found
    The requested URL was not found on this server."

    Next I dowloaded the 4.0.2 image and installed it on the Robotino.
    It seems to have a more complete rest-api but when I disconnect the VGA display, the Robotino shuts off after approximately 30 seconds.

    OK. Now I am convinced that the Robotino shutting off when the VGA is disconnected is a software issue and I guess you too are!

    My questions now :
    1. is it an Ubuntu issue (Ubuntu 18 vs Ubuntu 16) or a Robotino software issue?
    ​​​​​​​2. anybody has any idea on how to fix this?

      This is the "Lid closed bug". Disconnecting the VGA is interpreted as notebook closed.

      Please install the latest image from

      The latest ist currently 5.0.3-smartsoft-3.1.1

            1. go to '/etc/systemd/' and open logind.conf with gedit (sudo gedit logind.conf);
            2. replace the line "#HandleLidSwitch = suspend" with "HandleLidSwitch = ignore"; this will uncomment the line and changes the "Lid closed" action to do nothing (I guess);
            3. save the file.

            After restarting the Robotino, the problem seems to be fixed.
