Beat_Slayer has built a dual Arduino for his robot. He was talking about adding an nrf radio to communicate with it. That led me to wonder if there would be any use for having systems that have pairs, or, more of uC that only communicate via radio.
The thought that came to me was "left brain" "right brain" and the cross polination from more than one "whole brain". I am sure someone will help me flesh out or utterly kill the idea. :D
Any suggestions to help this make more sense to more people are readily accepted.
