Pupils in Japan have been given lessons by the world's first robot teacher.
The humanoid named Saya is multilingual, can do roll calls and set tasks from text books, according to The Sun.
'She' has a latex face, modelled on a university student, controlled by 18 motors to create expressions including happiness, surprise, fear, disgust, sadness and even anger.
Saya will start teaching full-time after passing a trial term at a Tokyo primary.
Her creator, science professor Hiroshi Kobayashi, had been working on the robot for 15 years.
The original, named Pikarin, had a metal head with exposed wires and levers.
