Researchers questioned if coordinated group movements by animals moving through a fluid could reduce the energy cost of locomotion. By combining biomechanics and bioenergetics the researchers found ...

A four-legged robot trained with machine learning has learned to avoid falls by spontaneously switching between walking, trotting, and pronking -- a milestone for roboticists as well as biologists ...

Walking on two legs is a rare and fascinating ability in the animal kingdom, observed across birds, mammals, and even small rodents. From waddling penguins to hopping kangaroos, these creatures have ...
