In the animal world, many species change theirappearance so that predators do not see them. The chameleon is perhaps the most famous example. The famous lizard can change its skin color to blend in with its environment. In a new paper, the researchers tried to match this ability with a chameleon robot.

To create a robot, scientists started with a layer of skin,made from liquid ink. Its color changes when a small amount of heat is applied. This caused the ink particles to form into spiral structures that reflected light at specific wavelengths. Different amounts of heat created structures of different sizes, which made it possible to display almost any desired color. The team then created a second layer of skin made up of a network of heating strips. The researchers then applied the skin to a chameleon model they had created.
They later added special color sensors tobelly and diagrams on the inside of the robot. The information received by the device was transmitted to the skin heating system so that the color changes depending on the environment.
Researchers have demonstrated the robot's ability to change color on demand by posting a video in which it crawls across a panel of colored areas.
