SternisheFan tips news of a robot designed by Harvard University researchers that can change colors to blend into its surroundings (abstract). The robot also has a soft, flexible body, and is driven by air pumped into cavities in its legs. "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.'"
