MIT’s Color-changing Robot ‘skin’ Was Inspired by the Golden Tortoise Beetle

Researchers at the Massachusetts Institute of Technology have created a 3D-printed robot “skin” capable of changing color according to the physical stimuli that it receives. The work was inspired by the so-called “goldbug,” a golden tortoise beetle, which changes color in the wild.

“I was googling online about two and a half years ago, looking for creatures that change their color, and found out about this beetle,” project leader, Subramanian Sundaram, an MIT graduate student in electrical engineering and computer science, told Digital Trends. “The golden tortoise beetle is incredibly interesting. One of the things it does is that, when it’s disturbed or scared, it drains out the fluid in its shell which is normally golden in color, but becomes a reddish-brown. I was interested by the idea that this beetle was able to respond to mechanical disturbances by changing the color and transparency of its outer shell. I thought we might be able to replicate that.”

Modern-Day Witchcraft: This Hair Dye Changes Color

Last year, Lauren Bowker was halfway through a nostalgic re-watching of the cult ’90s teen film The Craft when the idea struck. More specifically, it was during the “glamor spells” scene, when Robin Tunney’s character goes from brunette to platinum blond just by combing her fingers through her hair. “It was in that moment that the penny kind of dropped,” says Bowker, “I was like, ‘We could do that.'”

That wasn’t posturing: As a chemist, fashion designer, and the founder of the London-based material design studio, The Unseen, Bowker is something of a high-fashion alchemist. Her color-changing leather purses and otherworldly wearable Air sculptures are a measured mix of stunning aesthetics and seriously complex science.

Color-changing fabric

We haven’t quite figured out how to make a real invisibility cloak yet, we are coming up with better ways to camouflage ourselves. And what better way to do that than taking a cue from nature? Wouldn’t it be cool if we could change the color of our clothes like the chameleon changes the color of its skin? Textile designer Judit Eszter Karpati may have found a way to do that, thanks to the use of an experimental fabric she created that changes color on the fly. (Video)

The creature was discovered in a flower bed and now draws hundreds of followers to the home where it is kept in Thiruvananthapuram, Kerala.

Now one of India’s top zoologists has decided he will study the unusual creature – provided it can be kept alive.

Reji Kumar, 35, a lift worker, said he is doing its best but the frog has lost its appetite…
