It doesn’t use sticky pads, claws or magic but a technique called Electroadhesion (It’s basically a static charge, like you get from rubbing a balloon on your head) which allows it to climb pretty much any flat surface.

It looks quite cool and it would be awesome if it could suspend itself from a ceiling, but I doubt it could support much weight.

There’s a video over at bbc.co.uk and more information at SRI international
