Gordite is the seventh Rogue to be built, and its body will have a slightly larger diametre, which is now feasible as we can 3D-print the vertebrae rings instead of relying on fixed diametre ready-made wooden rings. It will be equipped with the phoretic hub to accompany the other two phoretic rogues.

I'm contemplating whether two Rogues could communicate via a liquid in a tube. One Rogue could send data to the other, by encoding it at least with one bit / two states / two liquids. I can think of is an interleaving of two distinct liquids, e.g. a transparent and a dark one (here I try with distilled water and espresso). This is the first attempt, so many things are not well done yet. For instance, there seems to be a lot of air in the tubes, and having a distance between the valves and the pump means that when changing the valve, a lot of stuff from the just closed valve is still sucked in by the pump... Also lots of bubbling. A sensor, for instance LDR, to detect the different liquids on the receiving end, is still missing. Also, how to convey a “clock signal”? The motor is probably too fast and too loud, I might try with a smaller tube diameter.

Another possibility is to “sink” the liquid, for example into a cloth or absorbant material. The receiving Rogue would sense the communication through an increase in humidity.
