Gecko feet robot.

Looks like robots are finally catching up with gravity defying lizards...

Researchers have created a robot that can run up a wall as smooth as glass
and onto the ceiling at a rate of six centimeters a second. The robot currently
uses a dry elastomer adhesive, but the research group is testing a new
geckolike, ultrasticky fiber on its feet that should make it up to five times
stickier.

Although if stickiness of the feet translate to speed then 5*6cm/s = 30cm/s, and I can tell you the geckos at my house can easily do 2m/s when a cat is chasing them.

I suggest they stick one of these in the room and see how fast it goes !
