CHILDREN do it with ease, but walking on two feet is challenging for robots. And while animated characters stroll along quite happily, they rarely look human when they do. That's because the many joints of a human body can move in multiple directions, creating a bewildering array of potential poses. Marshalling them to make a humanoid walk is no simple matter. "It's like driving a car with 50 steering wheels," says Michiel van de Panne, a computer animation researcher at the University of British Columbia in Vancouver, Canada, who is one of many trying a new approach to giving robots and video game characters more realistic gaits.
