A robot that acts as a friend for lonely astronauts in space has today been honoured with two Guinness World Records titles.
Kirobo, a small android able to have conversations in Japanese, has set records for first companion robot in space and highest altitude for a robot to have a conversation following an 18-month stay onboard the International Space Station.

Able to stabilise itself in zero-gravity conditions, its onboard voice synthesis coupled with a library of pre-set gestures and an advanced language processing system allows it to speak in an uncannily natural manner.

One of the project’s main aims was to test if a robot could provide psychological support to a human subject experiencing severe loneliness - such as an astronaut during an extended stay in space - by acting as their conversational partner.
Kirobo left earth via a HIIB rocket on 4 August 2013, with the mission to serve as a companion robot to the astronaut, Koichi Wakata.
After arriving at the ISS on the 10th, Kirobo gave its first speech eleven days later, declaring:“On August 21, 2013, a robot took one small step toward a brighter future for all.”
The humanoid went on to achieve the highest altitude for a robot to have a conversation record on 7 December 2013 at an altitude of 414.2 kilometers above sea level after succeeding in having multiple meaningful conversations with Wakata.
On February 10, Kirobo came safely back to Earth aboard SpaceX’s CRS-5 Dragon cargo supply spacecraft which splashed down in the Pacific Ocean off California, arriving back in Japan on March 12.
Kirobo’s first words after returning home were: “From up above, the Earth glowed like a blue LED.”
