Korean Scientists Build Chameleon Robot



Chameleons are known for the unusual ability to change the color of their skin. They do this to blend in with their surroundings and hide from predators or preys.

Now, a team of researchers at Seoul National University (SNU) has built a robot inspired by the famous reptile. Like the chameleon, this robot is able to adjust the color of its body to match the background.

The robot is covered in a special ¡°smart skin¡± made of liquid crystal ink. This ink can change into any color by the manipulation of its temperature, which the robot does through strips of heaters underneath the skin.

The robot is shaped like a chameleon and moves like a small reptile. On its underbelly, there are sensors that can detect colors. So, as it moves, the robot can identify the colors and simple patterns on the floor. Then, it turns on its heaters to match these colors and blend in with its surroundings.

Amazingly, the color changes that happen on the chameleon robot are nearly instantaneous. In one video released by SNU, the robot is seen maneuvering over a floor divided into various colors. Within half a second of crossing into a different area, a new color spreads throughout its body.

During the demonstration, the chameleon robot showed that it could effectively hide against a backdrop of plants and flowers. Indeed, the researchers say that in the future, this technology could be used by the military to camouflage soldiers and equipment.

Also, the researchers say they now plan to build other robots based on color-changing animals. Their next project will be based on the octopus, whose movements will be much more challenging to emulate.

Questions:
1. What makes chameleons unusual?
2. What gives the robot the ability to blend in with its surroundings?
3. Reveal the researchers' next project based on color-hanging animals.
4. What other ways can this technology be used in the future?

5. If you were to create a piece of technology to improve your life, what would this be and why?
