Video: A robot that uses whiskers to get around

This is really interesting. Robots that copy the movements of dogs for mobility and now robots with whiskers. Animals like dogs, cats, and rodents have been using whiskers forever. They manage to find there way along without any light at all. Now we have the mechanical equivalent. Objects that give off light also give away their position and can be blown up or otherwise destroyed. Marvelous for stealth along with GPS and other stuff to gather positional information, terrain, barriers, etc. Pretty cool.
