Honestly the ship robots have no purpose. Annoying dialog, no affection gain, no crafting bonus, horrible healing ability, and no dps other than running up and punching things... which usually gets them killed. They need work on them. Give them affection, give them crafting bonuses, give them the ability to use blasters or have a blaster part. O and increase their ability to heal. That would at least put them on par with the other companions.
