Hello everybody,
I have been searching and didn´t find an answer yet. I hope you can realy healp me.
If I try to run the code
"from poppy.creatures import PoppyHumanoid
poppy = PoppyHumanoid()"

It just says :

"WindowsError                              Traceback (most recent call last)

      1 from poppy.creatures import PoppyHumanoid

WindowsError: [Error 2] The System can´t find the data"

If I try to run the simulation with the “v-rep” simulation everything works great.

It seems to be related with our method to find available serial port in Windows.

Which windows version are you using?

Thanks for your fast reply.
I am using windows 10 since a few month.

Unfortunately I don’t have a windows 10 setup to test and check exactly how to solve the problem.

Yet, there is a “simple” way to solve the problem. You can directly specify the serial COM port you are using in the robot configuration file (poppy_humanoid.json) instead of the ‘auto’ value.

I’ll try to come with a proper fix in the next release.

When I got you right, I think this Solution works on communicationg over the USB port ?
I tried to connect poppy with my Leptop via ethernet because when I connected Poppy via USB it happens nothing. So my Leptop doesn´t even recognize that there is something connected via USB. Using the ethernet cable i at least can connect to Poppy (simply using “Ping poppy.local”). I think i schould have mentiont this at the top :D.

Thanks :slight_smile:
