Actor robots have made their debut on the Japanese stage.
A play has had its premiere at Osaka University where two robots star alongside the humans.
The robots were programmed to speak lines with human actors and move around the stage with them.
The play is called "Hataraku Watashi" ("I, Worker") and is set in the near future.
The story is based on a young couple who own two housekeeping robots. But one of them loses its motivation to work and complains it has been forced into boring and demeaning jobs.
It then enters into a discussion with the humans about its role in "life".
