In case you can't read my handwriting it says: My limbs are mechanical and work in the same manner as prosthetics. They are detachable, but when attached they can't be moved more than a door and a half or so from my torso due to a sort of magnetic field built into my synthetic body. The exception would be if they are turned off or out of power.
As previously states, they are controlled similarly to prosthetics. As an android, I have a synthetic humanoid internal system, including an artificial brain, heart, and organs. All I have to do is think about preforming an action, and my brain sends signals to the limbs allowing this action to be preformed. That's the simplified explanation, anyhow.
So in the case that one of my limbs were to be taken from my body, I couldn't make it return, but given in was still in range I would be an,e to control it until I could retrieve it.
Obviously I would use this ability to beat the ever loving shit out of the theif with my missing arm. >:3
