A GECKO-like robot with sticky feet could soon be scampering up a wall near you. See a video of the robot in action here (24MB mov file).

Geckos can climb up walls and across ceilings thanks to the millions of tiny hairs, or setae, on the surface of their feet. Each of these hairs is attracted to the wall by an intermolecular force called the van der Waals force, and this allows the gecko's feet to adhere.
