Climbs Walls And Stick
Researchers at Carnegie Mellon University (CMU) have developed a gecko-like robot with uber-sticky fibres on its feet - only this robot's feet are twice as sticky as those of a real life gecko. This enables the robot to climb walls.
Having said that, we saw another version of robot Geckos in 2006... Which robot do you like best?
Implications - Personally, I find it hard to vote for anything but this one. The video is so ridiculous as to almost not be real. For any true fans of science fiction films, this Carnegie Mellon creation will help you get closer to your favorite other worldly movie.
