The Kibo Robot Programming Challenge (Kibo-RPC) is an educational program that invites students around the world to solve various problems by programming free-flying robots (Astrobee and Int-Ball) in the International Space Station (ISS). The program is a collaboration between the Japan Aerospace Exploration Agency (JAXA) and the National Aeronautics and Space Administration (NASA), and it is designed to inspire students to pursue careers in science, technology, engineering, and mathematics (STEM).
