Researchers in Japan just created a tiny, amoeba-inspired robot

A robot is movement, controlled. This is as true for plane-sized flying machines as it is for micrometer-sized contraptions, like the amoeba-inspired robot recently created by researchers at Japan's Tohoku University. It isn't the smallest robot ever made, as there are a few robots at the nanometer scale, but it's one of the smallest robots whose movement can actually be controlled.
