Japanese astronaut bids farewell to robot companion

Japanese astronaut Koichi Wakata is wrapping up his mission aboard the International Space Station.

He is leaving behind a mechanical friend, a humanoid robot named Kirobo, who has been his companion for the past six months.

The robot's makers claim it can process questions and construct answers without resorting to pre-programmed responses.
