The only robot minion I might find usefull would be one who is generating montary riches and leaves me admiring caterpillars in the garden or whatever else I like to do.
Who knows what kind of caterpillar this big beauty is? What will it become?
You can see a big caterpillar and a little one. Both have a kind off sting and big looklike eyes spots.
After all I am a lot more interested in living objects. Maybe a robot that could build cute yellow minions like in the despicable me movies could tempt me though.
