How do I unlock all the special Kairobots?

Question

In Kairobotica, you can research various items, and you get either a special Kairobot, another item, something you can sell in your gift shops, or useless junk.

I find that the special Kairobots are super useful, and I love knowing what they are and what they do.

What items do I need to research to unlock each one?
