As laborers they could have parts of their designs that are adaptable to whichever job they undertake. Like, your guy could have extra memory space so when he contacts all the other races he isn't in danger of forgetting anything. This would make is so that he's a little less "Tough" I guess you could say since, if they wanna keep the same all around shape, the memory banks would take up space that would otherwise be used for "Muscle" or "Weapons" or stuff like that.

We could go this route: They can connect with one another over long distances since it made work easier, but once a droid "Dies" the only memories they can leave behind are ones recorded externally. This was to keep them in line. Each android can remember interaction with the dead droid, but any shared memories are erased. They kept the feature to help those left behind to move on and not dwell on the shared memories. What cha think?
