A toaster cannot make a toast alone. It has to be inserted and removed and put on a plate. That's what I want a robot for (one day, after I am sure, it will not accidently toast me).
The question is, is this actually worth it over a toaster with climate-controlled toast-hopper that dispenses directly onto a clean plate from a plate dispenser.
And if that feels too expensive and space-intensive for mere toast, just think of how much worse a robot would be!
