Record-Breaker Kirobo Returns From Space

31 March 2015

Robot-astronaut rewarded with two Guinness World Records for its work on board the International Space Station

Robots in space were once the stuff of sci-fi adventure, often equipped with death rays or displaying a dangerous streak of rebellion towards their humanoid masters. Today’s real-life astronaut-robot has proved itself a more trustworthy machine: Kirobo, created by Toyota in a joint research project, has returned to earth from a working trip on board the International Space Station to be rewarded with two Guinness World Records certificates.

Kirobo, devised and produced by Toyota with manufacturing, technology and academic partners in Japan*, spent 18 months on the ISS, during which time it conducted the first conversation experiment between a robot and a human – astronaut Koichi Wakata – in space. This helped advance research into how humans and robots might co-exist in the future.

Kirobo returned to earth on board a cargo supply craft, splashing down in the Pacific Ocean off California. Its first words once back home in Japan last week were: “From up above, the Earth glowed like a blue LED.”

At a debriefing session at Tokyo’s National Museum of Emerging Science and Innovation, project members gave a summary report and screened a film of the highlights of Kirobo’s activities during its time on the ISS.

Erika Ogawa, Guinness World Records’ Japan Vice President, then presented Kirobo with two certificates. The citations read: “The first companion robot in space is Kirobo (Japan), which arrived at the International Space Station on 9 August 2013” and “The highest altitude for a robot to have a conversation is 414.2 km above mean sea level and was achieved by Kirobo (Japan) on the International Space Station on 7 December 2013.”
