3 inches chameleon-inspired robot changes colour in real time

A soft robot that can change colour in real-time to match its background like a chameleon could pave the way to new forms of military camouflage.

The 'artificial chameleon skin' that covers the segmented back of the walking plastic-bodied robot was developed by a team led from the Seoul National University.

Built to resemble the animal, the little walking robot is 1 foot and 3 inches (38 cm) long, some six inches (15 cm) wide and weighs in at 2 lbs (0.9 kg).
