"Zero Robotics" is a robotics programming competition in which the robots are SPHERES satellites located inside the International Space Station (ISS).
The competition started online, where teams competed to solve an annual challenge guided by mentors. Participants created, edited, shared, saved, simulated and submitted code, all from a web browser.
After several phases of virtual competition, finalists were selected to compete in a live championship aboard the ISS. An astronaut will conduct the championship competition in microgravity, making Zero Robotics the world's first robotics competition held in space.
