Researchers at Harvard University have created a robot that can change color in seconds, allowing it to blend seamlessly into a background like a chameleon, or stand out so that it is easy to see.
It can even glow in the dark, and change its temperature.
These are just the latest additions to a family of rubbery, bendable robots first described in a 2011 paper published in the Proceedings of the National Academy of Sciences by the Whiteside Group, a Harvard-based research group.
The group was interested in creating a robot that was soft, rather than hard and breakable like most of the robots we know. And so they looked to the sea. This robot's design was inspired by invertebrates like squid and starfish and other animals with no hard skeletons.
The squishy robot moves by having air pumped through small cylinders in its body, and is flexible enough to squeeze through a glass plate elevated just 2 centimeters above the ground in under a minute, according to a report in the BBC.
