Scientists say frogs jumping mechanism could be used in robots. Some types of frogs can leap very long distances in relation to their size. Now, researchers say they have some answers explaining such extraordinary abilities.

Researchers at Brown University in Rhode Island recorded frog leaps with highly sensitive x-ray video cameras. They say a split second before jumping; the frogs shortened the muscles in their legs. That stretches the tendon connecting the muscle to the bone.

Loaded with energy, the tendon then recoils like a spring, propelling the frog forward and upwards. Scientists say their findings could lead to the development of elastic propulsion systems in robots. Source
