Chinese researchers develop robot chameleon
Chinese researchers have developed a robot that can change color based on his background. The camouflage technique want to take to the researchers show how future vehicles and armor in the background.
plasmonic chameleon The robot chameleon is made with a 3D printer, after which the robot is covered with plasmonic screens. The aim of the research is to create a method for active camouflage to adapt quickly to his background. In order to achieve this goal, researchers have opted for plasmonic modulation. Plasmonic nanostructures of metal can in fact be used to tune both optical reflection and absorption. As a result, can change the displays of color if use is made of the interaction between electric fields and nanostructures.
The researchers have made the displays by making use of a glass plate with a pattern of holes, each at 50 nanometer distance. gold was placed in these holes. Thereafter, the glass plate was placed in a housing of electrolytic gel with silver ions. By changes in the local electric field sticking the silver ions to the gold surface, which changes the color screens.
When light falls on the gold nanostructures, this produces plasmons that determine the reflection and absorption characteristics. When this happens, the screen appears red. If then be added with an electric field of silver ions, which alters the properties and is produced a different color.
The robot can detect the color of its surroundings. On this basis, the electric field can be adjusted in order to get the desired color. At this time, the chameleon robot is only able to produce the colors red, green and blue. The next step is to make available all the colors. “This robot chameleon can blend into its environment,” said researcher Wang Guoping.Viewing:-157
