Robot astronaut Kirobo takes part in conversation experiment aboard International Space Station

Dentsu Inc. (Dentsu), the University of Tokyo's Research Center for Advanced Science and Technology (RCAST), Robo Garage Co., Ltd. (Robo Garage) and Toyota Motor Corporation (TMC) announce today that on December 6, 2013, Japan Aerospace Exploration Agency (JAXA) astronaut Koichi Wakata and robot astronaut Kirobo held a conversation experiment on board the International Space Station (ISS).

The conversation, the first of its kind between a human and a robot in outer space, represents the latest development in the Kibo Robot Project, a joint research project carried out by Dentsu, RCAST, Robo Garage and TMC. JAXA is also providing extensive assistance.

Experiment content:

1. Autonomous conversation using voice recognition technology

2. Communication with people on Earth

Extract from the conversation experiment (translation)

Wakata: How did you get out here into space, Kirobo?

Kirobo: On the Kounotori* from Tanegashima Space Center.

Wakata: Right. So you came here on the Kounotori?

Kirobo: Not the bird, of course! A rocket.

Wakata: It's incredible that you came here all by yourself.

Kirobo: Well, I'm a robot!

*Name of the H-II Transfer Vehicle used with the H-IIB Launch VehicleFurther conversations will be held, and conversation logs and other data will be utilized by the project participants. The key aims of the project are to facilitate the coexistence of humans and robots, and to explore possible future deployment of communication robots in outer space.
