In a science lab in Seoul, a strangely awkward animal waddles across a striped platform. Its skin changes color to match each band it reaches: red to green to blue. This “chameleon” is a mechanical robot that works with technology designed to mimic the ability of God’s celebrated color-changing lizard.
Ko Seung-hwan is a mechanical engineering professor at Seoul National University in South Korea. His team researches color-changing robotics. Like many scientists before him (see Algae for Blindness), Ko took inspiration from creation—specifically color changes in chameleons. His team of researchers has created a camouflaging “skin.”
A special ink on the bot’s skin changes color in response to temperature. How? Tiny sensors relay information about surrounding colors to a computer. The computer knows the temperature required for each color. It commands tiny heaters to produce the proper temperatures to copy them.
“It’s walking around and also changing color at the same time,” Ko says of the robo-lizard. “So it’s kind of like a full, working chameleon.”
The flexible, multi-layered artificial skin is less than a hundred micrometers thick. That’s thinner than a human hair! By adding layers with simple shapes such as dots, lines, or squares, the skin can create complex patterns.
Not surprisingly, chemist Steven Morin says making a color-shifting robot was complicated. Problems included reaction time (how quickly the robot adapts to a new color) and unpredictable patterns—spots? stripes? both? The challenges make the fact that God made not only the chameleon but also every animal and insect on Earth with just His word (Hebrews 11:3) even more amazing!
Ko says creating a wearable device that can actively change its color and patterns in real time was one goal of the study. He envisions his research as working for military uniforms to help soldiers blend into their surroundings. But he also imagines uses in the fashion, automotive, architecture, and computer (display) industries.
Researchers still have work to do in the field of artificial color-changing robots. Someday, researchers hope to use the lessons of the chameleon bot to wrestle with the challenges of another color-changing creature: the octopus. This time, the engineering tasks will include the octopus’ unique movement style.
In a recent Smithsonian article, engineer Chengyi Xu expressed wonder at the design of self-camouflaging creatures. “Everything is just so sophisticated,” he says. It seems despite what science develops, God’s originals still work best.
Why? Science illustrates and often takes inspiration from creation, which recognizes God’s power and creativity, shared with His image-bearers who act as sub-creators in His world.
Pray: For eyes to see the wonder of God’s infinite creativity and glory; for researchers who work hard to build technology to better our lives.

My Ferrari got me in 2nd! VRRRMMMM!!!!!
why would they invent this? sometimes I wonder why they would take the time to invent these things, for what reason does this exist
Jonathan what is with the
Jonathan what is with the "ferrari" thing?
U stated that this was not a race track. but it is!!
WHY do you do this
this is cool.
I was trying to explane this to my mom!!! then I realized it was sorta like a mood ring. ever heard of one of those.
That must have been rather difficult :).
This is London
Yah it is like a mood ring except those things obviously don’t work XD
This is much more complex. pretty cool
That's a shame....I always loved those things :).
me have lambo i took it racing once and i won we should race ur ferrari against my lambo
say what ??!!
say what ??!!
It could be cool. If they
It could be cool. If they keep working on that kind of technology then we might get cool things like invisibility cloaks or something.
Creepy yet cool
If they can make this, think of what else they can make......
This is really cool!
Can I get a suit of this material?
They should use this
They should use this technology to create camouflage suits to use as an advantage for war.
What a good idea!
That is so cool! Someday, it could camouflage soldiers!
Also, I love mood rings and the invisibility cloak thing reminds me of Harry potter :)
Dana na nana
Harry goes to howarts he
Harry goes to howarts he meets Ron and Hermione, McGonagal requires he play for griffendor, Draco is a daddy's boy, Quirll becomes unemployed, the sorcerer's stone is destroyed by Dumbledore. . HPBook1
This is JENNA
Since I have nothing to add to this Harry potter/car race thing, I shall start my own thing. Though nobodys gonna see this, the fact that they are trying to replicate the chameleon is because everybody has been on this camouflage spree. I mean @Asher R asked why someone would spend time on making a robot chameleon. The answer is probably because they are going to build a bigger version of sorts. One that is usable to a human. (⊙_⊙;)
I think they would invent this to maybe study how they can take God's creation and potentially use it for human benefit. Although, sometimes inventions like this can seem kinda pointless.
oops forgot to add
oops forgot to add that the comment above was from Lucy C.
Sorry Xander K but It’s
Sorry Xander K but It’s totally a racetrack. Hahaha
