SternisheFan writes "A robot that can change colour to either blend in with or stand out from its surroundings has been created by Harvard scientists. The team thinks the devices could have a variety of different uses. Lead author Stephen Morin said the soft machines had similarities with organs or tissues and could have medical applications. He explained: "The idea is that if you have a system that can simulate muscle motion very well and a system that can transport fluid, by combining those you can fabricate that device to fit a specific surgical problem. "
The team also said the machines could have a future in search and rescue. Prof Whitesides said: "For that kind of application, having it be able to advertise itself, for example, in a way that stood out against the dark would be a good thing.""
