A team of scientists at Kobe University in Japan has designed a computer based on the activities of a large group of soldier crabs. The logic gates of the computer exploit the swarming behavior of the crustaceans to compute and accomplish tasks more efficiently. The concept is a form of biomimicry, where systems and elements in nature help solve and improve human problems.
By unleashing 40 real crabs into a specially created channel, the scientist observed their behavior and designed logic gates that mimicked the pattern of the crabs. The findings can possibly help create an unconventional computing model.
