Well everybody, I finally found a good quality upload for the Cubix Series from 2001:

My disappointment with Netflix's "The Electric State" gave me an overpowering desire to return to the turn of the century an revisit the colorful world of "Cubix", where robots are everywhere, sharing a world with humans. Cubix is just a Saturday morning cartoon from 2001 but it brings a joy to me that movies seem unable to duplicate.
