How about a look at Starfleet robots? I realize that we never really saw such (mostly because of budgetary restrictions), but I find it inconceivable that with all of the technology they have in that time, there seem to be no robots performing dangerous or tedious tasks, or even simply filling roles that even the least-ambitious person might find either demeaning or just plain boring. Where are the mining 'bots, the waiter-bots (an android would be overkill for such a task, don't you think?), the space-borne construction 'bots, the surgical 'bots?
Just a thought
