London: Japan's space agency is considering putting a talking humanoid robot on the International Space Station to watch the mission while astronauts are asleep.
It would also monitor their health and stress levels and communicate to Earth through the microblogging site Twitter.
The mission under consideration would be in 2013, reports the Daily Express.
Japan does not have a manned space programme of its own but its astronauts have been part of the space station crew.
Japan also maintains a laboratory, called Kibo, or Hope, on the space outpost.
