Researchers at Harvard have created the first self-camouflaging soft robot. The robot is mobile and has the ability to recognize the color of its environment and mimic the surrounding colors.  Using pumped microfluids, the robot is able to quickly hide itself within its environment.

The robot must be tethered to a central control system which pumps the liquids into its transparent body.  It is able to alter its colors with great specificity in approximately 30 seconds.

As the robot only costs $100 per unit to produce, it is a very cheap method for military operations requiring mobile stealth.

Of course, it will go to the military first.  I wonder when we will be able to implement this fluid adaptability in our cars.
