Octopuses show scientists how to hide machines in plain sight

Scientists have engineered a material that can transform from a 2D sheet to a 3D shape, adjusting its texture to blend in with its surroundings, per a new study published today in Science. They mimicked the abilities of an octopus, which can change both shape and color to camouflage.

Why it matters: This is a first step toward developing soft robots that can hide in plain sight, robotics expert Cecilia Laschi writes of the research. Robots that can camouflage may one day be used in natural environments to study animals more closely than ever before or in military operations to avoid detection, she writes.
