Freedrive_mode() argument 'a' and 'v' must be positive

Steps to reproduce:
call the script function freedrive_mode(), without any inputs, multiple times in a row without caliing end_freedrive_mode()

Expected Behavior:
would expect the the robot to go into freedrive and stay in freedrive

Actual Behavior:
Crashes with a Error popup saying freedrive_mode: argument ‘a’ and ‘v’ must be positive

Workaround Suggestion:
downgrade to 5.11 or remember to end freedive mode before starting it again.

Robot Serial Number:
in house robot: 20225201500
and two more with unknown serial number out in the field

Affected Version(s):
both version 5.12.1.xxxx and 5.12.2.xxxx seems to have the issue


Hi, I’m seeing the exact same problem, were you able to work around it?


I was able to figure out what the issue is.

This error happens if you continuously send a freedrive _mode() command. The fix for me was to send the command and then basically go into a loop with a wait inside until I want to exit the command or stop the program.



Hello @cg1,


This is an example how it would work. You just start the Freedrive mode and then make a query for the User which says “Freedrive is now active!” or something like this. When the User now presses the “Yes”-button the if-query ends the freedrive mode with “end_freedrive_mode()”

The freedrive is active till you press the button, the programs basiclly waits for your input.

Best regards

Hi Jorge and Matthias
Thanks for the response, nice to know that the error can be mediated.
I will make the changes suggested, but would still consider it a bug because of the change in behavior between versions, it would at least be nice with a better error popup…

and Again Thanks
