Caption: The image of a rat sniffing around for food with its little whiskers moving back and forth to help satisfy its appetite is enough to make most people lose theirs! But those whiskers play a valuable role in helping rats determine what is in the environment around them. Now Mitra Hartmann and colleagues at Northwestern University in Chicago are constructing whiskered robots that can detect and then project 3-D virtual images of objects on to a computer screen. Scientists here don't think it's so far fetched that one day robotic rovers, much like the ones on Mars now, might contain a set of whiskers to help them navigate the terrain around them.
