Erika the talking robot

Erica is a humanoid robot designed to look, sound and conduct conversations like a real person.

She was designed by Professor Hiroshi Ishiguro, director of the Intelligent Robotics Laboratory at Osaka University.

Professor Ishiguro's ambition for Erica is to make her as human-like as possible.

Erica is currently conversant in around 20 subjects, from her favourite hobby to what type of animals she likes.

The BBC's Rupert Wingfield-Hayes spoke to Erica about her favourite film.
