Game Story

The ISS air leak that occurred in 2020
has been repaired by talented programmers in Asia.
Everyday back on the ISS ...

Because only an emergency measure was taken, the air leak recurred in 2021.

The location of the leak has already been identified.
Asian programmers,
do a complete repair and report completion of the mission to the astronauts!

※ This is a fictional story.

Game Rules

  • Move Astrobee and read the AR tags and the QR code
  • Analyze the position/orientation of the target from information obtained from the QR code.
  • Adjust Astrobee's position/orientation and illuminate the center of the target with Astrobee's laser.
  • Finally, report completion of the mission to a crew member. Your score is calculated from the accuracy of laser pointing and the elapsed time.
Game Flow
This is an overview of the rules. Please refer to the Rulebook for details.

Purpose of Kibo-RPC

The Kibo Robot Programming Challenge is an educational program in which students solve various problems by programming free-flying robots (Astrobee and Int-Ball) in the International Space Station (ISS).
The Kibo-RPC will inspire students to develop their educational and professional goals to a higher level.

Participants will have the opportunity to learn cutting-edge methodologies and hone their skills in science, technology, engineering, and mathematics through this program.

The Kibo-RPC will also expand international exchange by encouraging students to interact with other participants from around the world.

History of Kibo-RPC

1st Kibo-RPC

Held in 2020
A total of 1,168 students comprising 313 teams from seven countries/region
has participated in the Kibo-RPC.

Robot Introduction



Astrobee, NASA's new free-flying robotic system, will help astronauts reduce the time spent on routine duties, allowing them to focus more on things that only humans can do.



Int-Ball is a free-flying camera robot aiming to ultimately reduce crew time to zero for routine video-shooting tasks by crew in ISS/Kibo.
