The study, which used treadmills, shows that people walking on two legs use 25% of the energy

But there is one thing that is beyond even our closest relatives, chimpanzees. And that is the ability to be spiteful. Keith Jensen and his team at the Max Planck Institute for Evolutionary Anthropology at Leipzig, Germany, conducted experiments in w
Roboticists are using the lessons of a 1930s human physiologist to build the world's fastest walking robot. RunBot is a self-learning, dynamic robot, which has been built around the theories of Nikolai Bernstein. "Getting a robot to walk like a human requires a dynamic machine," said Professor Florentin Woergoetter. RunBot is a small, biped robot which can move at speeds of more than three leg len
