"Zero Robotics" is a robotics programming competition where the robots are SPHERES satellites inside the International Space Station. The competition starts online, on this website, where teams compete to solve an annual challenge guided by mentors. Participants can create, edit, share, save, simulate and submit code, all from a web browser. After several phases of virtual competition, finalists are selected to compete in a live championship aboard the ISS. An astronaut will conduct the championship competition in microgravity with a live broadcast!
