MIT scientists have developed an amazing 3D-printed robot ‘skin’ that changes color in response to physical stimuli.
What!

That sounds like a cameleon skin, changes the color as according to environment

This is interesting news. I am now imagining owning a robot fitted with such skin. It would take away the boredom of staring at a fixed-color robot.

Hmmm. What stimuli are we talking about?

Anyway, this invention is a truly amazing one.
I wonder whether the MIT scientists were propelled by a specific practical concern.
