Imagine robots that operate without electronic components. Well, this week scientists at a robotics lab in Japan revealed a creation that could bring the scenario a step closer to reality. The team has created what looks to be a Technicolor inchworm made of motile gel that not only crawls by itself, but changes color depending on the environment it's in. And its creators say that this creeping, self-propelled goop might one day find its way into robots.
