Gecko-Bots wear Gecko Boots! Imagine a robot scampering up a smooth wall or upside down across a ceiling. Canadian scientists have exploited the molecular secrets of lizard’s feet which cling to surfaces using very weak molecular interactions known as van der Waals forces (unlike strong covalent or ionic bonds). Multiplied by thousands, these weak attractions can support not only the gecko but an impressive 133 kg weight! Now, a tank-like robot uses a synthetic material, polydimethylsiloxane, to mimic van der Waal attractions. This breakthrough is better than older methods using sticky glues, energy expensive suction or vacuums, magnets, spines or claws..which all have their limitations. I only wish the bots were as colorful as the geckos!

madame scientist's not-so-mad musings 
In fact, the force is so strong that some species of gecko could theoretically support the weight of an entire human.
I already had a lot of respect for the geckos, due to their mosquito eating skills, but now my admiration grew exponentially…
Also, when I first read the heading of your post I misunderstood it for “Gecko boots”! Not that gecko bots aren’t amazing, but imagine gecko boots!
João Figueiredo , I have edited my lede accordingly! 🙂
Aw, that’s a leopard gecko in the top right pic! I used to keep those. They’re great pets. They don’t actually have the sticky gecko feet, though — they just have regular, non-sticky lizard feet with little claws. But they’re still considered geckos for whatever reason.
Liz Krane , I love Latin names..so just for fun, here goes. Leopard geckos are Eublepharis macularius / Eu= good or real, blepharis =eyelid, macula = spots. Because they have eyelids and spots. 🙂
how magic??
