High-latency messaging via lego robot courier

Wireless doesn’t necessarily have to mean radio waves. If you’re worried about people listening in on your conversations, why not use a courier instead? This is a solution I developed as part of my degree programme at the University of Aberdeen. At each end are two VT100 terminals, these connect to the robot through tin foil contacts at each end of the board. A switch on the robot lets it know that it’s hit the wall and (hopefully) docked with the contacts.
