        "transcript": "<p>Researchers at Harvard University have made a soft, flexible robot that can actually change colors, enabling its use in places where machines shouldn't be noticed.</p><p>Here, a robot is walked onto a layer of rocks, and a dye is activated to change its color, so that it blends in to its surroundings.</p><p>The robot is made of silicon rubber. Plastic tubing connects it to a control system, and the dye is transferred through the tubes.</p><p>The robot moves as air is forced through a network of tiny channels inside the robot.</p><p>Here, the robot walks onto colored leaves.  And in this case, a fluorescent dye is pumped through the robot to make it stand out, and it's easier to find.</p><p>A chemo-luminescent dye can be used to make the robot glow in the dark, similar to animals like fireflies.</p><p>The temperatures of the dyes can be changed, too, so the robot can change color in the infrared spectrum.</p><p>Some snakes, for example, can sense infrared light using specialized organs.</p><p>The robot can be adapted for use in animal-behavior research or public display situations when invisibility helps lead to the best results.</p><p>This development appears in the August 17th issue of Science magazine.</p>",
