I think, THINK, because I haven't played roboticist, they're the only ones without outpost access in the science division?
I have basically two different suggestions here.
The first is giving all of science basic access to the outpost, simply to use the dorms. All the other big departments have some kind of private area nearby and science doesn't really. The break room definitely doesn't count. I did a scene in there because I thought it was relatively unused and I was surprised how many people popped in. One of them even got slightly mad. It's a decent walk to anywhere private, otherwise, for a xenobio/xenobot There's two private dorms on the outpost, however.
In some aspects access to the outpost for the xeno part of science makes some sense. As an example, the flora and fauna reconstitution consoles are supposed to be used with fossils found on the asteroid. I have yet to find or be given anything that works, but, that's supposedly what they're for. I can't think of a reason robotics would need to access the outpost, though, aside from lewds in outpost dorms.
Other suggestion is a dorm/shower area like engineering and security have, for general science access.
