Most home or entertainment robots I see are either manual human remote control or have the processor on-board and are completely self contained. Contrast to this robots which are neither, but are controlled wirelessly by a cpu elsewhere not in the body. Another cpu in the body is there merely to relay commands and readings back wirelessly to and from the main cpu. A hypothetical example of this are the battle droids from Star Wars, which were controlled by a "droid control ship", without which they were helpless. So this is the type of robotics architecture I am referring to. I have built such a robot already, so this is really a robotics question, not a science fiction question. I just wanted to convey the architecture I am referring to with a well known example.
What is the term for the physical shell?
What is the term for the main external cpu that houses the actual algorithm?
If the term "robot" applies, Which entity is the term "robot" more appropriately applied to? Or are there other actual industry terms which specifically classify the components in this architecture? I'm after the most widely accepted terms that still are precise.
