Robot That Changes Colors And 'Camouflages'

Scientists, are still trying to figure out the question of HOW real chameleons change color and researchers at the Wuhan University in China. The engineers have designed and built a lizard-shaped robot that can camouflage and change colors, to flawlessly and accurately match its surroundings. This robot was made by a 3D robot model that included plasmonic displays (Click here to see what plasmic displays are). According to the article, "The displays are made by drilling 50 nanometer holes into glass sheets, and then putting gold on the glass so it creates tiny domes within each hole. The glass is finally encased in an electrolyte gel full of silver ions."  When some sort of light hits the displays, it forms plasmons ("ripples of electrons", according to the article) that then make the display's reflection from light absorb the property. Also, the robot has a powerful and strong light sensor that can detect the background color that it needs to match perfectly. Unfortunately, this robot can ONLY match and produce the colors red, blue, and green. It seems like this robot can do pretty much two things or actions at once. It can detect color with the light sensors, and replicate the exact same color on the display area. How this robot works, is similar to how a chameleon would camouflage and adapt to colors to its surroundings.  This robot can display the reflected color from the light/color sensors it has. In order for this robot to completely work, it has to have working light sensors, and the plasmonic displays. The light sensor work comes before the display because the sensors are Part A, and have to detect the color from the reflected-light, so then in Part B, the plasmonic display can showcase it (this would make it 'camouflage').

​Thoughts, Ideas and Opinions

After reading this article, I noticed that this robot uses a lot of multitasking. By multitasking, I mean that this robot can do several things at once like: it has working color and light sensors to detect the background color,  and shows this exact same color on the platonic displays. This, is also another form of great technology  that can be beneficial in the future of robotics. This process of color detecting from reflected light is something that can still be worked on by the engineers at the Wuhan University because for now, the 'chameleon' robot can only display and exactly replicate the colors red, green, and blue. I think that if more colors can be successfully detected, and then replicated, they'd be a wide range of color that the robot has the ability to show.  (I wonder what other purposes color detecting can be used for?) I also think that it is amazing how this robot can accurately detect and show a color in a quick and efficient matter, but yet still be correct. Also, I think that this also gave possible ideas to scientists on HOW chameleons can be able to adapt and to change color based on their surroundings. This is also a good way to be using the helpful color/light sensors, so things that the robot performs is precisely accurate. Even though this is still the beginning stages of the work from engineers at Wuhan University, there's still room for revision, and to add final touches to their 'camouflaging chameleon robot.'
