So, I know that robots are thought to be kind of at the bottom of the to-do list at the current moment, but I would like to suggest this to resolve a major issue, and that is that there is no way to actually be able to tell different felibots apart without the rigger going out of their way to appear unique. And even then it is only going to be combinations of Green, Grey, or Brown (for the most part).
Would it be possible to add a robot part that just displays what the robot is christened somewhere on their look description? I'd just suggest neck for a collar for companion models and just a name badge on the chest area. It might add some intrigue for when you see a cat on Green or Blue without a collar.
This should probably go a great way towards clearing up any confusion about what exactly we can know about a robot when it does suspicious things and how exactly to tell them apart.
