This is the most basic furry meme format, yes it does refernce pornography, that's because the fandom was made for pornography; this can be seen in internet archive pre internet furry convention vids featuring 90% naked or in intercourse 'furries'.
From urbandictionary.com:
"Protogen
A species resembling cyborgs; they are 60% biological and 40% robotic. They have visors capable of displaying countless emotions. [...] Their limbs can be changed out because they're entirely modular. [...]"
40% robotic does kind of sound like a robot.
If you'd like to disagree, why not post a detailed description of its anatomy or something?
