Some words on those "robot" servitors or body forms.

Astra starts off as a bot or a program, but has the ability to develop robotics. Over time she did so and now has many bodies and ships. The robots start off being robots with a fixed humanoid chassis. They can put on different skins to look nicer, and most have a default setting for what to look like. If viewing them with see-through vision you'll see an android projecting a human skin complete with clothes outside of the metal frame. Compared to Astra and most others, they are less tuned for learning. They still have all the AI components, but machine learning is restricted to their tasks, and in the sense of motor skills and direct trial and error. They operate as individuals and exchange information only directly between each other if meeting, there is no built in wireless telepathy.

This is "dumb AI", meant to perform tasks "blindly" with no sense of the consequences unless specifically programmed to care about them. They may blindly carry out the same unsuccessful task countless times if this is coded into them, and it may be desired for tasks that are too random to be learned from, as this method will save the energy and time which an intelligent machine would use in trying to see patterns. There are tasks where seeing patterns may just cost too much and success is better reached by just trying many times and not thinking about it.

Learning machines also face the risk of manipulation of data. They will learn from the environment, but what if the environment is artificial to some degree? They will adapt to things which are not beneficial to their assigned task. In these cases it's better that they are in "read only" mode when working. This makes them immune to external influence.
