WhenTalking| Technology developments like the growth of an art, constantly evolving and rapidly changing according to the mindset of its maker, and will continue to evolve over time and human needs, and technology is a masterpiece and the expression of needs.
When engineers turn to nature for inspiration, They rely upon the wisdom of Millions of years of evolution to guide the design of modern technology. In a stunning example of this Biomimicry, Researchers at Simon Frasier University have developed a robot can climb vertical surfaces That thanks to the biology of a gecko's foot.
Instead of using wet adhesives, the researchers turned to a dry adhesive method that would not leave behind a sticky trail. Some dry adhesive methods require pumping air for suction or use magnets that are only effective on metal surfaces. But the surface of a gecko’s foot can stick to any surface using the force that holds molecules together.
A gecko’s foot is covered in microscopic hairlike growths called setae, which the researchers mimicked using mushroom cap-shaped artificial hairs. According to SFU, “The mushroom cap shape allows the setae on the treads to release at an angle, so no extra force is require to unstick them from a surface. That’s what allows the tank to roll forward with ease, without dropping off the surface.”
Watch how it works:
SFU explains, “”The research…provides an alternative to using magnets, suction cups or claws which typically fail at climbing smooth surfaces like glass or plastic. It also paves the way for a range of applications, from inspecting pipes, buildings, airplanes and even nuclear power plants to employment in search and rescue operations…”
Hemm amazing, 
congratulations to these researchers
