Japanese Scientists Create Computer Out of Soldier Crabs

Japanese Scientists Create Computer Out of Soldier Crabs

A team of Japanese scientists at Kobe University, lead by Yukio-Pegio Gunji, have built a computer out of live crabs. Before you imagine a bunch of crabs shoved into a laptop casing, the reality is that the researchers were able to utilize the predictable nature of soldier crab swarms to build logic gates, the basic AND/OR problems that are the building blocks of computing. The team published a paper on their findings in the journal Complex Systems (PDF). As reported by Gizmag , the behavior that the scientists were exploiting was what happens when two swarms of soldier crabs coming from different directions meet up: they meld into one another and operate as one, heading in the same direction that's at the combined angle of where they came from. The scientists used this behavior to design two different logic gates. The first, shown below, is a basic OR gate that consists o...
