What does platonic twin mean here?
I scooped up one of the detached nanoprobes. In reality, the drones mimicked my intentions with their own manipulators, picking up the nanoprobe's platonic twin...Then I jammed it recklessly into Janos's head, into his occipital lobe.
This paragraph is quoted from a short Sci-fi story Dilation Sleep by Alastair Reynolds. In the context, the protagonist was doing a surgery for Janos with the help of the drones and nanoprobe. Because the author didn't mention platonic twin before, I researched the meaning of platonic: (of love or friendship) intimate and affectionate but not sexual. Also I found twin flame: the other half of your soul. Combining these two words together might have something to do with the relationship. I'm guessing this is a coined term to describe a device which supplements the nanoprobe, but I'm not sure.
