Soft robot chameleon changes color in real-time to match background

A team of researchers working at Seoul National University has developed a soft robot chameleon that can change its colors in real time to match its background. In their paper published in the journal Nature Communications, the group describes their multi-layer skin design and possible uses for it. In the animal kingdom, many species change their appearance to prevent predators from seeing them--the chameleon is perhaps the most famous example. The famous lizard is able to change the colors of its skin to blend in with its surroundings. In this new effort, the researchers have attempted to match that ability with a robot chameleon.
