I second that - not all settings have the same attitude towards robotics: Firefly has almost none, Babylon 5 has very few (and mostly all spaceborne), while Andromeda is full of robots of all shapes and sizes. In most Traveller settings, I use (relatively) dumb robots in the background, doing menial jobs where a machine has a clear advantage over man; guard-bots are also common as they never tire (and only have to be maintained weekly or so; refueling is daily but quite short) unlike their human counterparts - the same robot does all three shifts with full alertness, saving money on the long run and being more secure (though you'll probably add some Human guards as most guard-bots are less smart than Human guards). War-bots I usually use as heavy weapon platforms, especially in cultures that haven't developed the Battledress yet (and even later, a basic warbot is cheaper than a battledress).It depends on the era one is playing...
Golan2072:
Ofcourse, in TNE most people would distrust robotics, so most robotics would be limited to "background" manufacturing/lifting jobs and be quite dumb and thus hard to infect.
not very common IMTU
why let robots do all the dangerous stuff when there are plenty of willing stooges.
The worlds of traveller average a million or so souls each (not sure if this was modified after CT) - that's not exactly 'teeming', especially when every world is striving to upgrade its TL as quickly as possible. I can see a considerable market in scrap or 'damaged repairable' robots on most worlds. And they don't cost 10,000, 8,000 or even 1,000Cr each to import. They have considerably lower running costs than humans too, especially in hostile environments. I imagine the manufacturing costs will be a small concern in the long run.
