Here is another cool robot inspired by nature. Researchers have built these Click beetle-inspired robots that move using elastic energy. These insect-sized jumping robots can perform tasks in small spaces. The finding were published in the Proceedings of the National Academy of Sciences. The below video shows how they work:
As Sameh Tawfick and his team explain:
The jumping mechanism uses dynamic buckling cascading and allows for a single stroke from a coiled artificial muscle to actuate an automatic sequence of shape transformations in a buckling beam
