Engineering: Gecko Grippers

Over millions of eons, evolution has tailored adaptations to environments everywhere on Earth. Engineers are now adapting some of the most successful evolutionary designs using bio-mimicry as a guide. Designers at the Jet Propulsion Laboratory in Pasadena, CA are looking closely at the feet of geckos, lizards that can climb upside down, to tailor their new Gecko Gripper robots to crawl over difficult surfaces on Mars or anywhere else needed.
It is called Crazy Engineering at CalTech laboratory but it is very intelligent engineering as well.
