• Resumen

  • In 1938, the American inventor John Wilson filed a patent for a toy that, when placed on a gentle slope, would walk on two pivoted legs with a comical waddling motion that served to lift the swinging foot clear of the ground. Wilson's "Walkie" waddled its way to success, and its descendants can be found in toyshops to this day. It took a while to discover the secret, but two-legged robots can at last get around as gracefully as humans. Ball elaborates its transitions.
