Hi. I actual wrote (and I am still writing) all of the Andrayada background. As posted above, the Andrayada have two processing units, a central one in their head and one at the base of their spine. This allows them to remove their lower half and legs, and plug directly into a new piece of equipment. Essentially, the main brain sends 'move forwards' messages to the auxiliary brain, which then moves using the hardware 'legs'. There are several reasons for this development. Firstly, the Andrayada are initially Pax constructs, and so they were designed for a specific purpose and given a humanoid form to utilise Pax vehicles and equipment. Secondly, the old idea of a 'brain in a box' AI neglects the importance of sensors and emodiment, and the important link between an agents physical form and capacity to learn.
Let me put it this way, could you learn a language just by reading a book? It would be very difficult without being able to physically point to objects, to pick things up, to gesture, etc.
The 'crew-bot' still recieves sensory information via the vehicle that they are crewing directly, but transplanting the brain into the vehicle would actually be a shock, even for a robot.
... And the vehicles look cooler and wer sculpted with windows!
Anyhow, this also works for the space craft, where Andrayada run on rails around the vessel.
Sorry to go on.... I actually have a background in robotics.
