User blog comment:Madlooney6/Unknown and article needing robots/@comment-1718103-20120706131818

I think the only one of these that might be even worth speculating about. The Rampage robot seems logically connected to the Series 2 machine, obviously because of name and also because the two robots feature the same font on the wording. Perhaps an upgraded version? I don't think any other machines are worthy of articles, or even guessing at their origins
