World's first robot citizen 'Sophia' gets her own legs

Just months after she made history by becoming the first robot to be granted legal citizenship, Sophia has been given legs. The humanoid robot, which is capable of holding a conversation with humans, can now move forward in a series of clunky steps. Sophia represents a remarkable'rise of the machines' that promises – or threatens – to revolutionise man's relationship with technology. The talking humanoid robot, which is modelled after Audrey Hepburn, was designed by Hong Kong firm Hanson Robotics, which claims Sophia can hold a conversation with humans. Sophia first emerged two years ago as a super-intelligent human-like head with a realistic face that was able to blink, look from side to side and talk.
