Larasen gave Kam a bit of a wishy-washy head bobble as he considered his answer.  "Well, the 'maintenance droid' I built isn't really a droid in the sense that it doesn't have any autonomy.  It's hooked in to the ship's systems and basically keeps track of any issues going on, and I can give it commands on what to do, but it won't fix anything on its own since it lacks the heuristic processor.  It's not ideal, but I haven't ever worked with freighters and didn't have any maintenance droids on me at the time when I joined the crew.  I could build a proper astromech droid for you, but it would be kind of expensive, also might result in me losing a job."
